The individual brush bodies and the associated movement mechanisms, interacting with the head part, are however also to be considered as independent disclosures, in particular if the pairings of the brush bodies have no coupled movements. Represented restoring members and damping elements are to be considered as independent disclosures to the same extent.

(102) The toothbrush 1, as is represented with regard to its basic construction in FIGS. 16g and 16h in the context of an embodiment variant of the brush head, comprises a main body 2 with a grip part 3 for holding the toothbrush 1 by hand. The main body 2 moreover comprises a head part 6.1-6.21 (corresponds to: 6.1, 6.2, 6.3, 6.4, 6.5, 6.6, 6.7, 6.8, 6.9, 6.10, 6.11, 6.12, 6.13, 6.14, 6.15, 6.16, 6.17, 6.18, 6.19, 6.20, 6.21) as well as a neck part 4 connecting the head part 6.1-6.21 to the grip part 3.

(103) The head part 6.1-6.21 can be designed corresponding to one of the embodiment examples according to FIG. 1 to 21. The head part 6.1-6.21 together with subsequently described brush body or brush bodies 10a-410a; 10b-410b (corresponds to: 10a, 10b; 20a, 20b; 30a, 30b; 40a, 40b; 50a, 50b; 60a, 60b; 70a, 70b; 80a, 80b; 90a, 90b; 100a, 100b; 11a, 110b; 120a, 120b; 150a, 150b; 160a, 160b; 170a; 180a; 210a, 210b; 310a, 310b; 410a, 410b) forms the brush head 5.1-5.21 (corresponds to: 5.1, 5.2, 5.3, 5.4, 5.5, 5.6, 5.7, 5.8, 5.9, 5.10, 5.11, 5.12, 5.15, 5.16, 5.17, 5.18, 5.19, 5.20, 5.21) or a part of this. The head part 6.1-6.21 serves as a carrier for the brush body or brush bodies 10a-410a; 10b-410b which is/are arranged on this.

(104) The embodiments of brush heads 5.1-5.21 according to FIGS. 1 to 21, as mentioned each comprise a head part 6.1-6.21. A first brush body 10a-410a as well as a second brush body 10b-410b is arranged on the head part 6.1-6.21 in each case. The two brush bodies 10a-410a; 10b-410b are arranged successively along the longitudinal axis L of the toothbrush 1. The first brush body 10a-410a is arranged in each case at the front on the free end-section of the head part 6.1-6.21. The second brush body 10b-410b is arranged in each case on the head part 6.1-6.21, at the rear towards the grip part 3.

(105) The first brush body 10a-410a comprises a first bristle carrier 11a-411a. The first brush body 10a-210a moreover comprises first cleaning bristles 12a-212a (not shown in FIGS. 20 and 21) which are arranged on the first bristle carrier 11a-411a. The cleaning bristles 12a-212a form a first bristle field.

(106) The second brush body 10b-410b comprises a second bristle carrier 11b-411b. The second brush body 10b-410b moreover comprises second cleaning bristles 12b-212b (not shown in FIGS. 20 and 21) which are arranged on the second bristle carrier 11b.411b. The second cleaning bristles 12b-212b form a second bristle field.

(107) According to the first and second embodiment variant according to FIG. 1a-1d as well as 2a-2d, the first brush body 10a, 20a in a plan view is designed in a round, in particular circularly round manner. The first brush body 10a, as a pivot element comprises a pivot pin 13a, 23a which is arranged on the first bristle carrier 11a, 21a, at the side which lies opposite the first bristle field.

(108) The pivot pin 13a, 23a and via this, the first brush body 10a, 20a are rotatably mounted on the head part 6.1, 6.2, in a pivot receiver or pivot opening or, as mentioned here, in a receiving opening 14a, 24a. The receiving opening 14a, 24a is designed as a continuous round opening in the head part 6.1, 6.2. The round opening does not however need to be continuous, but can also be designed merely as a deepening (recess). The pivot pin 13a, 23a as part of the first brush body 10a, 20a is connected to the head part 6.1, 6.2 via a snap-click connection and is axially secured by way of this. The pivot pin 13a, 23a and thus the geometric rotation axis R are arranged centrically.

(109) The free end of the pivot pin 13a, 23a which lies opposite the first bristle field extends beyond the head part 6.1, 6.2, at the other side of the continuous receiving opening 14a, 24a. First functional elements 15a, 25a such as nubs or lamellae which serve as a tongue cleaner are arranged on this free end. The tongue cleaner is accordingly movable relative to the head part 6.1, 6.2.

(110) The second brush body 10b, 20b is designed in an elongate manner. According to the first embodiment variant according to FIG. 1a-1d, the second brush body 10b comprises two guide elements, here guide pins 13b, which are arranged on the second bristle carrier 11b, distanced to one another along the longitudinal axis L.

(111) According to the second embodiment variant according to FIG. 2a-2d, the second brush body 20b only comprises one guide pin 23b arranged on the second bristle carrier 21b, analogously to the previously described guide elements.

(112) The guide pin or guide pins 13b, 23b are arranged on the second bristle carrier 11b, 21b, at the side which lies opposite the second bristle field.

(113) The guide pin or the guide pins 13b, 23b and, via these, the second brush body 10b, 20b are displaceably mounted on the head part 6.1, 6.2 in a translatory manner along the longitudinal axis L, in a guide opening, here a longitudinal opening 14b, 24b. The longitudinal opening 14b, 24b and the second brush body 10b, 20b with the guide pin or pins 13b, 23b therefore form a slide guide (carriage guide), i.e. a sliding guide, wherein the second brush body 10b, 20b corresponds to the slide.

(114) The longitudinal opening 14b, 24b is designed as a continuous opening in the head part 6.1, 6.2. The opening however does not need to be continuous, but can also be designed merely as a longitudinal groove. The guide pin or guide pins 13b, 23b as part of the second brush body 10b, 20b are connected to the head part 6.1, 6.2 via a snap-click connection and are secured against sliding out of the longitudinal opening 14b, 24b on account of this.

(115) The free end of the guide pin or pins 13b, 23b which lies opposite the second bristle field, in each case extends beyond the head part 6.1, 62, at the other side of the continuous longitudinal opening 14b, 24b. Second functional elements 15b, 25b such as nubs or lamellae which serve as a tongue cleaner are arranged at these free ends.

(116) The first brush body 10a, 20a is then brought into a rotational movement about a rotation axis R by way of the cleaning movement carried out manually with the toothbrush due to a to and fro movement, and by way of exerting a pressing pressure of the brush head 5.1, 5.2 onto the teeth.

(117) The second brush body 10b, 20b is moreover brought into a translatory to and fro movement along the longitudinal opening 14b, 24b, by way of the cleaning movement carried out manually with the toothbrush due to a to and fro movement, and by way of exerting a pressing pressure of the brush head 5.1, 5.2 onto the teeth. With this to and fro movement of the second brush body 10b, 20b, this is moved to the first brush body 10a, 20a and away from this again.

(118) The second bristle carrier 11b, 21b in a plan view moreover forms a concave recess towards the first bristle carrier 11a, 21a, and this recess is designed to receive a part-contour of the first brush body 10a, 20a. By way of this, it is ensured that the brush head 5.1, 5.2 forms an as continuous as possible bristle field, which is to say that the arising gap in the bristle field is kept as small as possible, during the cleaning movement and in every position of the second brush body 10b, 20b along its translatory movement path.

(119) The second embodiment variant according to FIG. 2a-2d moreover differs from the first embodiment variant, essentially in that the head part 6.2 on its rear side comprises third functional elements 26, such as nubs or lamellae, which serve e.g. as a tongue cleaner.

(120) According to a third and fourth embodiment variant according to FIG. 3a-3f as well as 4a-4f, the first brush body 30a, 40b is likewise round, in particular circularly round, in a plan view. The first brush body 30a, 40a comprises a joint head 33a, 43a which is arranged on the first bristle carrier 31a, 41a, at the side which lies opposite the first bristle field.

(121) The first brush body 30a, 40a is articulately mounted on the head part 6.3, 6.4, in a joint opening 34a, 44a via the joint head 33a, 43a. The joint opening 34a, 44a is designed as a continuous round opening in the head part 6.3, 6.4. The round opening however does not need to be continuous, but can also be designed merely as a deepening, e.g. as a type of joint socket. The joint head 22a, 43a as part of the first brush body 30a, 40a is stuck into the joint opening 34a, 44a via a snap-click connection, and is connected to the head part 6.3, 6.4 and is thus secured against jumping out of the joint opening 34a, 44a.

(122) The joint connection permits a deflection of the first brush body 30a, 40a in three directions. The deflection however is only possible over a part-periphery of the pivot circle.

(123) The second brush body 30b, 40b is designed in an elongate manner. According to the third embodiment variant according to FIG. 3a-3f, two encompassing elements 33 which are directed towards one another are formed on the second bristle carrier 31b. According to the fourth embodiment variant according to FIG. 4a-4f, in each case three finger-like encompassing elements 43b are formed on the second bristle carrier 41b per side. The encompassing elements 43b are directed towards one another at both sides.

(124) The encompassing elements 33b, 43b are directed towards the rear side of the head part 6.3, 6.4. The encompassing elements 33b, 43b encompass a longitudinal guide body 34b, 44b at the outer side, wherein this longitudinal guide body is shaped out of the head part 6.3, 6.4. The longitudinal guide body 34b, 44b has the function of a guide rail and, considered in cross section, is designed in a T-shaped manner. A different cross-sectional geometry however is also possible. The T-shaped longitudinal guide body 34b, 44b comprises a middle rib which is led through the encompassing elements 33b, 43b which are directed towards one another. The encompassing elements 33b, 43b with the second bristle carrier 31b, 41b form a slot-like receiving space receiving the flanks of the T-shaped longitudinal guide body 34b, 44b.

(125) The encompassing elements 33b, 43b and the longitudinal guide body 34b, 44b thus together form a sliding guide, which permits the second brush body 30b, 40b to be translatorily displaced on the head part 6.3, 6.4 along the longitudinal axis L. The sliding guide is a slide guide (carriage guide), wherein the second brush body 30b, 40b corresponds to the slide (carriage).

(126) The encompassing elements 33b, 43b ensure that the brush body 30b, 40b cannot detach from the head part 6.3, 6.4 transversely to the movement direction. The second brush body 30b, 40 can be pushed over the longitudinal guide body 34b, 44b, e.g. via a snap-click connection. The encompassing elements 33b, 43b have elastic characteristics for this.

(127) The first brush body 30a, 40a is now deflected out about the rotation point of the joint head 33a, 43a by way of the cleaning movement which is carried out manually with the toothbrush due to a to and fro movement, and by way of exerting a pressing pressure of the brush head 5.3, 5.4 onto the teeth.

(128) Moreover, the second brush body 30b, 40b is brought into a translatory to and fro movement along the longitudinal guide body 34b, 44b by way of the cleaning movement which is carried out manually with the toothbrush due to a to and fro movement, and by way of exerting a pressing pressure of the brush head 5.3, 5.4 onto the teeth. With this movement of the second brush body 30b, 40b, it moves to the first brush body 30a, 40a and away from this again.

(129) The second bristle carrier 31b, 41b moreover in a plan view forms a recess towards the first bristle carrier 31a, 41a, and this recess is designed to receive a part-contour of the brush body 30a, 40a. By way of this, it is ensured that the brush head 5.3, 5.24 forms an as continuous as possible bristle field, which is to say that the arising gap in the bristle field is kept as small as possible, during the cleaning movement and in every position of the second brush body 10b, 20b along its translatory movement path.

(130) According to the fifth embodiment variant according to FIG. 5a-5h, the first brush body 50a is round, in particular circularly round, in a plan view. The first brush body 50a comprises a pivot pin 53a as a pivot element, which is arranged on the first bristle carrier 51, at the side which lies opposite the first bristle field.

(131) The pivot pin 53a and, via this, the first brush body 50a are rotatably mounted on the head part 6.5, in a pivot opening, the receiving opening 54a. The receiving opening 54a is designed as a continuous round opening in the head part 6.5. The round opening however does not need to be continuous, but can also be designed merely as a recess. The pivot pin 53a as part of the first brush body 50a is connected to the head part 6.5 via a snap-click connection and is axially secured by way of this. The pivot pin 53a and thus the geometric rotation axis R are centrically arranged.

(132) The second brush body 50b is designed in an elongate manner and comprises a guide pin 53b as a guide element, which is arranged on the second bristle carrier 51b. The guide pin 53b is arranged on the second bristle carrier 51b, at the side lying opposite to the second bristle field. The guide pin 53b and, via this, the second brush body 50b are displaceably mounted on the head part 6.5, in a guide opening, the longitudinal opening 54b.

(133) The longitudinal opening 54b and the second brush body 50b with the guide pin or guide pins 53b thus form a slide guide, i.e. a sliding guide, wherein the second brush body 50b corresponds to the slide.

(134) The longitudinal opening 54b is formed as a guide groove in the head part 6.5. The opening however can also be designed in a continuous manner. The guide pin 53b as part of the second bristle carrier 51b is connected to the head part 6.5 via a snap-click connection and is prevented from sliding out of the longitudinal opening 54b by way of this.

(135) The longitudinal opening 54b runs obliquely to the longitudinal axis L, in contrast to the first and second embodiment according to FIGS. 1a-1d and 2a-2d, so that the second brush body 50b has a movement component along the longitudinal axis L as well as transversely to the longitudinal axis L. Moreover, the second brush body 50b considered transversely to the longitudinal axis L is guided over an arching. The lower side of the second bristle carrier 51b which lies opposite the second bristle field is concavely recessed in an equal and opposite manner. The movement transverse to the longitudinal axis L becomes a pivoting movement on account of this, with which pivoting movement the second bristle field, which is to say the bristle field of the second brush body 50b, is pivoted to the side about a geometric rotation axis.

(136) The first brush body 50a is now brought into a rotational movement about a rotation axis R by way of the manual cleaning movement which is carried out by the toothbrush due to a to and fro movement, and by way of exerting a pressing pressure of the brush head 5.5 onto the teeth.

(137) The second brush body 50b is moreover pushed to and fro along the longitudinal opening 54b by way of the cleaning movement which is carried out manually with the toothbrush due to a to and fro movement, and by way of applying a pressing pressure of the brush body 5.5 onto the teeth. Thereby, the second brush body 50b executes a combined movement which has a movement component along the longitudinal axis L towards the first brush body 50a and away from this again, as well as a lateral pivoting out (see FIGS. 5f, 5g, 5h).

(138) A position is shown in each case in the FIGS. 5f, 5g and 5h. Thereby, FIG. 5f shows the middle position when the second brush body 50b is located directly in the axis with the head part 6.5. FIG. 5g shows the position of the second brush body 50b with a maximal deflection to the left. FIG. 5h shows the position of the second brush body 50b with a maximal deflection to the right.

(139) According to the sixth embodiment variant according to FIG. 6a-6d, the first brush body 60a is designed in a round, in particular circularly round manner, in a plan view, and is fastened to the head part 6.1 in a stationary or rotatable manner.

(140) The second brush body 60b is designed in an elongate manner and is translatorily displaceable along the longitudinal axis L, towards the first brush body 60a and away from this again, via a sliding guide which is not explained in more detail here.

(141) A rubber-elastic restoring member 63 is arranged between the first and the second brush body 60a, 60b, at the side of the bristle field. The restoring member 63 in particular is designed from a soft component and as an arching element.

(142) The restoring member 63 is fastened with a first end to the head part 6.6 and with another end to the second brush body 60b. The design and fastening of the restoring member 63 are such that this arches given a displacement of the second brush body 60b from an initial position towards the first brush body 60a, by way of the reduction of the intermediate space between the first and the second brush body 60a, 60b, and in this manner is put under stress. The restoring member is designed as a flat element in the present example. The restoring member in a further development of the invention can also be designed as a ring-like element (not shown).

(143) The second brush body 60b is brought into a translatory to and fro movement by way of the cleaning movement carried out manually with the toothbrush due to a to and fro movement, and by way of exerting a pressing pressure of the brush head 5.6 onto the teeth. With this movement, the second brush body 60b moves to the first brush body 60a and away from this again.

(144) With the return movement, the second brush body 60b, given a reduction of the displacement force, is pushed back into its initial position again by way of the restoring force of the restoring member 63 which is under stress.

(145) Moreover, functional elements 64 in the form of cleaning bristles or lamellae are arranged on the restoring member 63. The functional elements 64 are arranged on the arching section of the restoring member 64, such that these move up and down given a to and fro movement of the second brush body 60b.

(146) The various extreme positions are recognisable by way of comparing between the two FIGS. 6c and 6d. FIG. 6c shows the initial position with a functional element 64 which is set more deeply and with an almost flat, rubber-elastic restoring member 63. The distance between the first brush body 60a and the second brush body 60b is maximal. FIG. 6d shows the position of the functional element 64 and of the rubber-elastic restoring member 63, in which the distance between the first brush body 60a and the second brush body 60b is at its smallest.

(147) According to the seventh embodiment variant according to FIG. 7a-7d, the first brush body 70a in a plan view does not have a completely round shape. The first brush body 70a as a pivot element comprises a pivot pin 73a which is arranged on the first bristle carrier 71a, at the side which lies opposite the first bristle field, and permits a rotation.

(148) The pivot pin 73a and, via this, the first brush body 70a are rotatably mounted on the head part 6.7, in a pivot receiver, the receiving opening 74a. The receiving opening 74a is designed as a continuous round opening in the head part 6.7. The round opening however does not need to be continuous, but can also be designed merely as a recess. The pivot pin 73a as part of the first brush body 70a is connected to the head part 6.7 via a snap-click connection, and is axially secured by way of this. The pivot pin 73a and thus the geometric rotation axis R are thus centrically arranged.

(149) The second brush body 70b is designed in an elongate manner and comprises a guide pin 73b as guide element, which is arranged on the second bristle carrier 71b. The guide pin 73b is arranged on the second bristle carrier 71b, at the side which lies opposite the second bristle field.

(150) The guide pin 73b and, via this, the second brush body 70b are mounted on the head part 6.7 in a translatorily displaceable manner along the longitudinal axis L, in a guide opening, the longitudinal opening 74b. The longitudinal opening 74b and the second brush body 70b, with the guide pin 73b thus form a slide guide, i.e. a sliding guide, wherein the second brush body 70b corresponds to the slide.

(151) The longitudinal opening 74b is designed as a continuous opening in the head part 6.7. The opening however does not need to be continuous, but can also be designed merely as a longitudinal groove.

(152) The guide pin 73 as part of the second brush body 70b is connected to the head part 6.7 via a snap-click connection and by way of this is secured against sliding out of the longitudinal opening 74b.

(153) The second bristle carrier 71b comprises laterally arranged indentations 76. Moreover, restoring elements 75 of a soft component are arranged in the region of the slide guide in a manner projecting laterally from the head part 6.7. The restoring elements 75 in the initial position of the second brush body 70b are positioned in the indentations 76 of the second brush body 70b. The restoring elements 75 in each case comprise at least one cleaning bristle 77 which merges into the bristle field of the brush head 5.7.

(154) The second brush body 70b is brought into a translatory to and fro movement along the longitudinal opening 74b by way of the cleaning movement carried out manually by the toothbrush due to a to and fro movement, and by way of exerting a pressing pressure of the brush head 5.7 onto the teeth. The second brush body 70b thereby moves to the first brush body 70a and away from this again.

(155) With this movement procedure, the restoring elements 75 in the indentions 76 come to laterally abut with the brush body 70b or the bristle carrier in an alternating manner in each case. The elastic restoring members 75 are deformed and/or laterally deflected by way of the displacement force, due to the fact that they cannot slide out of the indentation 76. In this manner, on the one hand a damping effect is applied onto the moving second brush body 70b, and on the other hand the individual restoring element 75 also exerts a restoring force upon the moving second brush body 70b, bringing this back into its initial position. The restoring elements 75 thus form a restoring member.

(156) The first brush body 70a is moreover brought into a rotational movement about a rotation axis R by way of the cleaning movement carried out manually with the toothbrush due to a to and fro movement, and by way of exerting a pressing pressure of the brush head 5.7 onto the teeth.

(157) The first brush body 70a likewise comprises a restoring element 78. This restoring element is elastically deformed by way of the deflection as is the case with the elements on the second brush body 70b, and thus leads to a restoring of the first brush body 70a into the initial position. The restoring element 78 is fastened directly to the head part 6.7. The restoring element 78 is additionally also designed as a cleaning element/functional element.

(158) According to the eighth embodiment variant according to FIG. 8a-8d, the first brush body 80a is designed in a round, in particular circularly round manner in a plan view. The first brush body 80a comprises a pivot pin 83a as a pivot element, which is arranged on the first bristle carrier 81a, at the side which lies opposite the first bristle field.

(159) The pivot pin 83a and, via this, the first brush body 80a are rotatably mounted on the head part 6.8, in a pivot receiver, the receiving opening 84a. The receiving opening 84a is designed as a continuous round opening in the head part 6.8. The round opening however does not need to be continuous, but can also be designed merely as a deepening. The pivot pin 83a as part of the first bristle carrier 81a is connected to the head part 6.8 via a snap-click connection and is axially secured by way of this. The pivot pin 83a and thus the geometric rotation axis R are centrically arranged.

(160) The second brush body 80b is designed in an elongate manner. Two encompassing elements 83b which are directed towards one another are formed on the second bristle carrier 81b. The encompassing elements 83b are directed to the rear side of the head part 6.8. The encompassing elements 83b encompass or engage around a longitudinal guide body 84b formed on the head part 6.8, at the outer side. The longitudinal guide body 84b has the function of a type of guide rail and is designed in a T-shaped manner considered in cross section. A different cross-sectional geometry however is also possible. The T-shaped longitudinal guide body 84b comprises a middle rib which leads through between the encompassing elements 83b which are directed towards one another. The encompassing elements 83b with the bristle carrier 81b form a slot-like receiving space receiving the flanks of the T-shaped longitudinal guide body 84b.

(161) The encompassing elements 83 and thus the second bristle carrier 81b and the longitudinal guide body 84 together form a slide guide i.e. a sliding guide. This permits the second brush body 80b to be translatorily displaced on the head part 6.8 along the longitudinal axis L. The second brush body 80b thereby corresponds to the slide.

(162) The encompassing elements 83b ensure that the brush body 80b cannot detach from the head part 6.8 transversely to the movement direction. The second brush body 80b can be transversely pushed over the longitudinal guide body 84b via a snap-click connection. The encompassing elements 83b have elastic characteristics for this.

(163) The second bristle carrier 81b comprises carrier sections 86 of a soft component which are arranged at both sides on the base of the encompassing element 83b. A cleaning element 87, such as a cleaning bristle or lamella, e.g. of a soft component is arranged on the carrier sections 86 in each case.

(164) A damping element 85 of a soft component is moreover fixedly arranged on the head part 6.8, between the first and the second bristle carrier 81a, 81b. The damping element 85 has elastic characteristics and executes a damping or buffer function with respect to the second brush body 80b. The damping element 85 is moreover a carrier of cleaning elements 88, such as cleaning bristles or lamellae, e.g. of a soft component.

(165) The cleaning elements 87, 88 mentioned above blend into the existing bristle field.

(166) The second brush body 80b is brought into a translatory to and fro movement along the longitudinal guide body 84b by way of the cleaning movement carried out manually with the toothbrush due to a to and fro movement, and by way of exerting a pressing pressure of the brush head 5.8 onto the teeth. The second brush body 80b thereby moves towards the first brush body 80a and away from this again.

(167) With this movement procedure, the second bristle carrier 81b towards the first brush body 80a comes to abut on the damping element 85 in each case. The abutting or striking of the second brush body 80a on the damping element 85 is damped on account of the elastic characteristics of the damping element 85. The damping element 85 can even exert a restoring force upon the second brush body 80b on account of an elastic deformation, with this procedure.

(168) Moreover, the first brush body 80a is brought into a rotational movement about a rotation axis R by way of the cleaning movement carried out manually with the toothbrush due to a to and fro movement, and by way of exerting a pressing pressure of the brush head 5.8 onto the teeth.

(169) FIGS. 9 and 10 show a first and a second type of slide guide for the second brush body, in combination with restoring members. The slide guide amongst others is described in detail in the embodiment variants according to FIGS. 2a-2d and 7a-7d. The restoring members have elastic characteristics, in particular on account of their shaping.

(170) FIG. 9 shows a longitudinal opening 134b in the head part 6.13. The guide pin 133b of the second brush body, as a guide element, is guided along the longitudinal opening 134b in a sliding manner, in the guide opening, thus this longitudinal opening 134b. A restoring member 135 of a soft or hard component is arranged in the longitudinal opening 134b, in each case on both sides of the guide pin 133b. The two restoring members 135 each comprise a fold structure with a zigzag pattern. The two restoring members 135 are connected in each case with a first end section to the guide pin 133b and with a second end section in the longitudinal opening 134b to the head part 6.13.

(171) The restoring members 135 are in a neutral position, i.e. they are relaxed, when the guide pin 133b is located in the middle of the longitudinal opening 134b. The fold structure of the restoring members 135 at the one side are pulled apart and at the other side are pressed together, by way of displacing the guide pin 133b along the longitudinal opening 134b. The pressed-together restoring member 135 then exerts a restoring force from a compressive stress, upon the guide pin 133b in the direction of the neutral position in the middle of the longitudinal opening 134b. The pulled-apart restoring member 135 likewise exerts a restoring force from a tensile stress, onto the guide pin 133b in the direction of the neutral position. The guide pin 133b and, with this, the second brush body, subsequently to a deflection is led back into the middle of the longitudinal opening 134b by way of the restoring forces of the restoring members 135 in this manner.

(172) FIG. 10 as a guide opening shows a longitudinal opening 144b in a head part 6.14. The guide pin 143b of the second brush body, as a guide element, is slidingly guided along the longitudinal opening 144b in this longitudinal opening 144b. A restoring member 145 of a soft or hard component is arranged in each case on both sides of guide pin 143b, in the longitudinal opening 144b. The two restoring members 145 have an arched structure. The two restoring members 145 with a first end section in each case form a contact section to the guide pin 143b. The two restoring members 145 are moreover connected in each case and with a second section in the longitudinal opening 144b, to the head part 6.14.

(173) If the guide pin 143b is located in the middle of the longitudinal opening 144b, then the restoring members 145 are located in a neutral position, i.e. they are relaxed. The arched structure of the restoring member 145 is pressed together at the one side due to the displacement of the guide pin 143b along the longitudinal opening 144b. The pressed-together restoring member 145 now exerts a restoring force from a compressive stress, onto the guide pin 143b in the direction of the neutral position in the middle of the longitudinal opening 144b. The guide pin 143b, and with this, the second brush body, subsequently to a deflection are led back into the middle of the longitudinal opening 144b by way of the restoring force of the restoring member 145 in this manner.

(174) The restoring members can also have a different shaping. A restoring member can also be arranged in the longitudinal opening at only one side of the guide pin, in the case that the restoring member in the longitudinal opening is connected on the one hand to the head part and on the other hand to the guide pin.

(175) FIGS. 11a-11b and 12a-12c show a ninth and tenth embodiment variant of a toothbrush according to the invention, with which the movement between the first and the second brush body 90a, 90b; 100a, 110b is coupled via a coupling element. The coupling element can consist of a hard component or soft component. The coupling element 93, 103 is designed in an elastic, which is to say flexible manner.

(176) The first brush body 90a, 100a is rotatably mounted on the head part 6.9, 6.10. The second brush body 90b, 100b is guided on the head part 6.9, 6.19 in a translatorily displaceable manner along the longitudinal axis. L. The manner of guiding is of a lesser significance according to these embodiment examples.

(177) According to the embodiment according to FIG. 11a-11b, the first and the second brush body 90a, 90b are directly coupled to one another via a coupling element 93, wherein this coupling element 93 is fixed to the first as well as to the second brush body 90a, 90b. The connection is such that the translatorily alternately displacing second brush body 90b brings the first brush body 90 into a likewise alternating rotation movement via the coupling element 93. The rotation movement however lies within a limited rotation angle, in particular of less than 180. The coupling element 93 executes the function of a push and pull element.

(178) If the second brush body 90b is displaced in the direction towards the first brush body 90a, then a movement of the first brush body 90a into a rotation direction is initiated via the coupling element 93, in particular until the two brush bodies 90a, 90b bear on one another. The two brush bodies 90a, 90b distance themselves to one another again when the second brush body 90b moves back again, and the first brush body 90a rotates in the opposite direction until the coupling element 93 is extended which is to say stretched.

(179) According to the embodiment according to FIG. 12a-12c, a coupling element 103 is arranged on the second brush body 100b. The coupling element 103 forms a contact section to the first brush body 100a, and the opposite side of the coupling element 103 is fixedly and directly connected to the second brush body 100b. The first brush body 100a has a cog-like peripheral structure, into which the coupling element 103 meshes with its contact section. The first brush body 100a according to this embodiment example only has one bristle row 102a, for visualising the rotation movement.

(180) The two brush bodies 100a, 100b interact in a manner such that the translatorily alternately displacing second brush body 100b brings the first brush body 100a into a rotation movement when contact is created via the coupling element 103. The contact section of the coupling element 103 springs into the next recess of the cog structure during the rotation.

(181) The first brush body 100a can be rotatably mounted in only one direction, thus can have a freewheel. By way of this, one succeeds in the first brush body 100a not rotating back when the second brush body 100b distances itself from this again, and the coupling element 103 drags over the cog-like outer geometry of the brush body 100a.

(182) The course of the movement of this principle of the drive of the first brush body 100a by the second brush body 100b is schematically represented in FIG. 12a to 12c. The procedure or course is in the sequence of the FIGS. 12c, 12b and 12a.

(183) FIG. 12c shows the initial position. The bristle row with the cleaning bristles 102a is represented in a first position. In FIG. 12b, the coupling element 103 comes into contact with the first brush body 100a and rotates this further, as is to be recognised by the position of the represented bristle row. The coupling element 103 is thereby deflected. The second brush body 100b is again represented in the initial position in FIG. 12a, when this is moved back and the first brush body 100a is located in a next engagement position. In a further movement sequence, the second brush body 100b again presses coupling element 103 onto the first brush body 100a and thus advances the rotation movement of the first brush body 100a.

(184) FIGS. 13a-13d and 14a-14c shows an eleventh and twelfth embodiment variant with alternative movement concepts for the brush bodies 110a, 110b; 120a; 120b.

(185) The brush head 5.11, 5.12 thus comprises a lifting element 113, 123 movably connecting the first brush body 110a, 120a to the head part 6.11, 6.12 which lies therebelow. The lifting element 113, 123 is thereby fastened on the lower side of the bristle carrier 111a, 121a which lies opposite the bristle field. The lifting element 113, 123 is designed and fastened on the head part 6.11, 6.12 in a manner such that the first brush body 110a, 120a is helically movable towards the head part 6.11, 6.12 and away from this, via the lifting element 113, 123.

(186) According to the embodiment variant according to FIG. 13a-13d, the second brush body 110b is articulately connected to the head part 6.11 lying therebelow, via two lifting elements 114 which are arranged distanced to one another. The lifting elements 114 are fastened on the lower side of the second bristle carrier 111b which lies opposite the bristle field. The lifting elements 114 are designed and fastened on the brush head 5.11 or on the head part 6.11 such that the second brush body 110b via the lifting elements 114 can be moved to the head part 6.11 and away from this, in the manner of a parallelogram.

(187) FIG. 13d shows the initial position of the two brush bodies 110a, 110b, when no force is exerted onto these. The lifting elements 113, 114 have a maximal angle with respect to the head part 6.11. The restoring forces of the lifting elements 113, 114 on account of the geometric shape act such that the mentioned initial position is reached again and again in the non-loaded condition.

(188) The first and the second bristle carrier 111a, 111b are pressed in the direction of the head part 6.11 during the application, by way of exerting a pressure upon the cleaning bristles 112a and 112b. The first bristle carrier 111a on account of the pressure undergoes a movement in the direction of the head part 6.11 and simultaneously a rotation in a direction which is set by the respective lifting element 113. The first bristle carrier 111a carries out a quasi screw (helical) movement.

(189) The second bristle carrier 111b executes a parallelogram-like movement given the application of a pressure. The parallelogram-like movement is a combined movement, on the one hand in the direction of the head part 6.11 and on the other hand in the direction of the neck part of the toothbrush, which is to say in a direction away from the first brush body 110a. The parallelogram-like movement in turn is set by the design of the lifting elements 114.

(190) The design of the brush bodies 110a, 110b and the head parts 6.11 with lifting elements 113, 114 thus encompasses two movement components. A first common movement component runs in the height, i.e. towards the head part 6.11 and away from this again. A second movement component either comprises a rotation about geometric axis or a translation away from the other brush body 110a and back to this again.

(191) FIG. 13c shows the initial position in a plan view. FIG. 13d shows a cross-sectional view of FIG. 13c. FIG. 13a shows the brush head on application of a pressure upon the brush bodies 110a, 110b. FIG. 13b shows a cross-sectional view of FIG. 13a.

(192) According to the embodiment variant according to FIG. 14a-14d, the second brush body 120b is designed as a rocker, with which the second bristle carrier 121b is mounted on a rocker pivot 124. The rocker pivot 124 is aligned transversely to the longitudinal axis L and lies parallel to the geometric cleaning plane. The second bristle carrier 121 can thus execute a rocking movement with respect to the head part 6.12.

(193) The movement of the brush bodies 110a, 110b; 120a, 120b relative to the head part 6.11, 6.12 is likewise activated by way of the manually executed cleaning movement of the toothbrush due a to and fro movement and exerting a pressing pressure of the brush head 5.11 and 5.12 respectively, upon the teeth.

(194) According to the thirteenth embodiment variant according to FIG. 15a-15e, the first brush body 150a in a plan view is designed in a round manner, in particular in a circularly round manner. The first brush body 150a as a pivot element comprises a pivot pin 153a which is arranged on the first bristle carrier 151a, at the side which lies opposite the first bristle field.

(195) The pivot pin 153a and, via this, the first brush body 150a are rotatably mounted on the head part 6.15, in the pivot receiver, a receiving opening 154a. The receiving opening 154a is designed as a continuous round opening in the head part 6.15. The round opening however does not need to be continuous, but can also be designed merely as a deepening. The pivot pin 153a as part of the first bristle carrier 151a is connected to the head part 6.15 via a snap-click connection and is axially secured by way of this. The pivot pin 153a and thus the geometric axis R are arranged centrically.

(196) The second brush body 150b is designed in an oval manner. The second brush body 150b comprises a pivot pin 153b as a pivot element, which is arranged on the second brush body 150b, at the side which lies opposite the second bristle field.

(197) The pivot pin 153b and, via this, the second brush body 150b are rotatably mounted on the head part 6.15, in the pivot receiver, a receiving opening 154b. The receiving opening 154 is likewise designed as a continuous round opening in the head part 6.15. The round opening however does not need to be continuous, but can also be designed merely as a deepening. The pivot pin 153b as part of the second brush body 150b is connected to the head part 6.15 via a snap-click connection, and is axially secured by way of this. The pivot pin 153b and thus the geometric rotation axis R are however arranged eccentrically with respect to the second bristle carrier 151b. For this reason, the second brush body 150b laterally deflects given a rotation movement about the rotation axis R.

(198) The two brush bodies 150a, 150b are commonly encompassed by a rubber-elastic encompassing element 155 which is attached directly to both brush bodies 150a and 150b.

(199) The second brush body 150b is brought into a rotation movement about a rotation axis R by way of the cleaning movement carried out manually with the toothbrush due to a to and fro movement, and by way of exerting a pressing pressure of the brush head 5.15 onto the teeth.

(200) Thereby, the second brush body pivots out laterally on account of the eccentric arrangement of the rotation axis R and exerts a deflection force onto the encompassing element 155. The deflection force effects a tensile stress in the encompassing element 155 which leads to a stretching (straining) of this. The first brush body 150a is set into rotation by way of the stretching movement of the encompassing element 155.

(201) The influencing of the movements is effected mutually, so that the first brush body 150 can bring the second brush body 150b into movement.

(202) According to a fourteenth embodiment variant according to FIG. 16a-16h, a second brush body 160b which is designed in a horseshoe-like manner is arranged on the head part 6.16. The horseshoe-shaped second brush body 160b forms two flexible limbs which enclose a receiving space. Both limbs have elastic characteristics and are movable laterally outwards by way of this. The elastic characteristics are achieved for example by way of flexible zones in the limbs or by way of the geometric design of the limbs. The limbs in particular consist of a hard component, so that the bristles can likewise be anchored. Cleaning bristles 162b which form a bristle field are arranged on the limbs. The receiving space is open to the free end of the brush head 5.16.

(203) A first brush body 160a which with a section reaches into the horseshoe-like opening of the second brush body 160b is arranged on the head part 6.16, towards the free end of the brush head 5.16. The first brush head 160a is guided in a translatorily displaceable manner along the longitudinal axis L via a slide guide. The slide guide comprises a guide groove 165 in the head part 6.16, as well as a guide element 166 on the first brush body 160a and guided in the guide groove 165. The guide element 166 is arranged on the first bristle carrier 161a, at the side which lies opposite the bristle field. The guide element 166 is inserted into the guide groove via a snap-click connection and is secured against sliding out. The slide guide can however also be designed differently.

(204) The first brush body 160a is brought into a translatory movement by way of the cleaning movement carried out manually with the toothbrush due to a to and fro movement, and by way of exerting a pressing pressure of the brush head 5.16 onto the teeth. The first brush body 160a is thereby pushed into the opening between the two limbs of the second brush body 160b. With this procedure, the first brush body 160a exerts a spreading force onto the two limbs. The two limbs as a result of this are pressed apart and deflect laterally amid the enlarging of the opening. The two limbs also retreat again back into their initial position on account of an elastic restoring force, with the retreat of the first brush body 160a out of the opening with the counter movement.

(205) According to a fifteenth embodiment variant according to FIG. 17a-17d, the brush head 5.17 in contrast to the preceding embodiment variants merely comprises one brush body 170a which is movably arranged on the head part 6.17.

(206) The brush body 170a is arranged at the front, i.e. on the free end-section of the head part 6.17. The brush body 170a comprises a bristle carrier 171 as well as first cleaning bristles 172a which are arranged on the bristle carrier 171. These first cleaning bristles 172a form a first bristle field.

(207) A second bristle field with second cleaning bristles 172b is arranged subsequently to the brush body 170a in the direction of the grip part. The second cleaning bristles 172b are anchored directly in the head part 6.17. The cleaning bristles can also be anchored in a bristle carrier of a second brush body fixedly arranged on the head part, as an alternative to this embodiment. The second bristle field as a whole is however not movable relative to the head part.

(208) The movable brush body 170a is designed in a round manner in a plan view. As a pivot element, it comprises a pivot pin 173 which is arranged on the bristle carrier 171, at the side which lies opposite the first bristle field.

(209) The pivot pin 173 and, via this, the movable brush body 170a are rotatably mounted on the head part 6.17, in a pivot receiver or pivot opening or, as mentioned here, a receiving opening 174. The receiving opening 174 is designed as a continuous round opening in the head part 6.17 The round opening however does not need to be continuous, but can also be designed merely as a deepening. The pivot pin 173 as part of the movable brush body 170a is connected to the head part 6.17 via a snap-click connection, and is axially secured by way of this. The pivot pin 173 and thus the geometric axis R are arranged centrically.

(210) The free end of the pivot pin 173 which lies opposite the first bristle field extends beyond head part 6.17, at the other side of the continuous receiving opening 174.

(211) The movable brush body 170a is now brought into a rotation movement about a rotation axis R by way of the cleaning movement carried out manually with the tooth brush due to a to and fro movement, and by way of exerting a pressing pressure of the brush head 5.17 onto the teeth.

(212) FIG. 18 shows a longitudinal section through a particular embodiment of a rotating brush body 180a. The rotating brush body 180a with regard to the design and arrangement on the head part 6.18 is designed in the same manner, with the exception of the subsequently described differences.

(213) In contrast to the embodiment variant according to FIG. 1a-1d, the cleaning bristles 182 are not arranged, i.e. attached to the bristle carrier 181 in a direct manner, or integrally manufactured with this, but are fastened on a carrier body 186. The cleaning bristles 182 are hereby fastened on the carrier body 186 by way of a so-called AFT method. This is effected by way of the cleaning bristles 182 being led through through-openings in the carrier body 186. Thereby, the end sections of the cleaning bristles 182 which exit out of the through-openings at the other end are melted amid the formation of a molten puddle. The cleaning bristles 182 are thus anchored in the carrier body 186 due to the re-solidified molten puddle. The carrier body 186 is subsequently fastened to the bristle carrier 181. The carrier body 186 is inserted into a deepening in the bristle carrier 181 for this.

(214) Yet further functional elements, such as soft-elastic bristles, can be attached on the carrier body 186. Further functional elements 185 are arranged on the pivot element 183.

(215) The first brush body 210a according to the embodiment variant according to FIG. 19a-19d is designed in a round, in particular circularly round manner, in a plan view. The first brush body 210a comprises a first bristle carrier 211a, on which first cleaning bristles 212a forming a first bristle field are arranged.

(216) The first bristle carrier 211a moreover comprises a pivot pin 213a which is arranged at the side lying opposite the first bristle field. The head part 6.19 comprises a pivot receiver or pivot opening for the rotatable mounting of the pivot pin 213a.

(217) The pivot pin 213a and, via this, the first brush body 210a are rotatably mounted on the head part 6.19, in the pivot receiver or pivot opening.

(218) The pivot opening is designed as a continuous round opening in the head part 6.19. The round opening however does not need to be continuous, but can also be designed merely as a deepening. The pivot pin 213a as part of the first brush body 210a is connected to the head part 6.19 and axially secured via a positive connection. The free end of the pivot pin 213a amid widening thereby extends beyond the head part 6.19 at the other side of the continuous receiving opening.

(219) The second brush body 210b is designed in an elongate manner and comprises a second bristle carrier 211b. Second cleaning bristles 212b forming a second bristle field are arranged on the second bristle carrier 211b. A sliding lobe 213b is moreover arranged on the second bristle carrier.

(220) The sliding lobe 213b is arranged on the second bristle carrier 211b at the side which lies opposite the second bristle field and is displaceable relative to the head part 6.19 along the longitudinal axis L, in a longitudinal opening 214b in the head part 6.19. The second brush body 210b is translatorily displaceable along the longitudinal axis L by way of this. The movement path is delimited by the length and the design of the longitudinal opening.

(221) The first and second brush body 210a, 210b or bristle carriers 211a, 211b are now coupled to one another via a coupling mechanism 215. The coupling mechanism 215 comprises a cog 217 which is arranged on the first bristle carrier 211a concentrically to the rotation axis R. The coupling mechanism 215 moreover comprises a rack 216 with a toothing, said rack being connected to the second bristle carrier 211b and being directed to the first bristle carrier 211a. The rack 216 with its toothing meshes on the cog 217.

(222) The coupling is now of such a nature that the alternately translatorily moved second brush body 210b brings the first brush body 210a into an alternating rotation movement via the coupling mechanism 215.

(223) The first and the second bristle carrier 211a, 211b thus together form a bristle carrier unit 220.

(224) Hereby, the rack 216 which is translatorily moved together with the second brush body 210b, on account of the meshing engagement, brings the cog 217 and, with this, the first brush body 210a into a rotation movement. The rotation movement however lies within a limited rotation angle of less than 360.

(225) The rotation angle amongst other things is defined by the toothing on the cog 217, the toothing length on the rack 216 and the possible translatory movement of the second brush body 210a.

(226) If the second brush body 210b is now translatorily moved to the first brush body 210a, then a simultaneous rotation movement of the first brush body 210a is initiated via the coupling mechanism 215. The two brush bodies 210a, 210b move away from one another again when the second brush body 210b moves back again in a translatory manner, and the first brush body 210d simultaneously rotates back in the opposite direction.

(227) The coupling mechanism 215 thus has the effect of the first brush body 210a or the first bristle carrier 211a simultaneously carrying out rotation movement, given a translatory movement of the second brush body 210b or the second bristle carrier 211b.

(228) According to the embodiment variants according to FIGS. 20a-20k and 21a-21k, the brush head 5.20, 5.21 comprises a head part 6.20, 6.21 as well as a bristle carrier unit 320, 420 which is assembled on the head part 6.20, 6.21.

(229) The bristle carrier unit 320, 420 comprises a first bristle carrier 311a, 411a which is designed in a round manner in a plan view, as well as a second bristle carrier 311b, 411b which is elongate in a plan view. The bristle carriers 311a, 311b; 411a, 411b each together with bristles (not shown) form a first and second brush body respectively. For this, the bristles carriers 311a, 311b; 411a, 411b comprise receivers for bristles, at the side which is away from the head part 6.20, 6.21.

(230) The bristle carrier unit 320 420 moreover comprises a coupling mechanism 315, 415 which mechanically connects the two bristle carriers 311a, 311b; 411a, 411b to one another.

(231) The first bristle carrier 311a, 411a is rotatably mounted and held on the head part 6.20, 6.21 in a receiving opening 314a, 414a, via a pivot pin 313a, 413a which is arranged on the first bristle carrier 311a, 411a, at the side which lies opposite to the first bristle field (not shown). The second bristle carrier 311b, 411b is mounted and held on the head part 6.20, 6.21 in a translatorily displaceable manner along the longitudinal axis L in a longitudinal opening 314b, 414b, via a sliding lobe 313b, 413b which is arranged on the second bristle carrier 311b, 411b, at the side which lies opposite to the second bristle field (not shown).

(232) According to the embodiment variant according to FIG. 20a-20k, the coupling mechanism 315 comprises a guide arm 316 which is centrally arranged, runs parallel to the longitudinal axis L and connects the two bristle carriers 311a, 311b, which is to say their pivot pins 313a and sliding lobes 313b to one another. The guide arm 316 in particular is of a hard plastic. The guide arm 316 in particular is designed as a separate component which is arranged on the rear side of the head part 6.21 which lies opposite the bristle field.

(233) The guide arm 316 is fastened on the sliding lobe 313b of the second bristle carrier 311b and is movable relative to this. The guide arm 316 in particular is hung in on the sliding lobe 313. The connection in particular can be a detent connection. The connection is preferably non-releasable or only releasable by destruction.

(234) The guide arm 316 is bent to the side in the region of the pivot pin 313a of the first bristle carrier 311a. The bent arm section of the guide arm 316 at its free end comprises a receiving opening for receiving a guide pin 317, said guide pin being arranged on the pivot pin 313a, radially to the outside with respect to the rotation axis of the first bristle carrier 311a. The receiving opening has play with respect to the guide pin 317 guided in the receiving opening. The receiving opening can e.g. be slot-like. The accommodation with play is necessary, in order to permit the subsequently described movement.

(235) The coupling mechanism 315 is designed and connected to the bristle carriers 311a, 311b such that a translatory movement of the sliding lobe 313b in the longitudinal opening 314b is transmitted onto the guide arm 316 and its receiving opening at the free end of the angled (bent) arm section.

(236) As a result of this, the guide pin 317 which is guided in the receiving opening is likewise brought into movement, by which means the first bristle carrier 311a executes a part-peripheral rotation movement about its rotation axis. The rotation angle can be 10 to 70, in particular 15 to 45.

(237) The movement of the guide pin 317 as a result is effected along a circular path about the rotation axis of the bristle carrier 311a, whilst the receiving opening on the bent arm section carries out a translatory moment. The guiding of the guide pin 317 in the receiving opening with play then ensures that no stresses are introduced into the guide arm 316 despite a different movement path. This is of particular significance if the guide arm is not elastic or is only elastic to a limited extent.

(238) The coupling mechanism 315 thus has the effect that the first bristle carrier 311a simultaneously executes a rotation movement, in the case of a translatory movement of the second bristle carrier 311b.

(239) According to the embodiment according to FIG. 21a-21k, the coupling mechanism 415 comprises a guide arm 416 which is arranged laterally on the bristle carrier unit 420, runs parallel to the longitudinal axis L and connects both bristle carriers 411a, 411b to one another. The guide arm 416 in particular is of a hard plastic.

(240) The guide arm 416 in the region of the pivot pin 413a of the first bristle carrier 411a is angled to the rotation axis R. The angled arm section of the guide arm 416 is thereby connected to the pivot pin 413a of the first bristle carrier 411a. The angled arm section in particular is hung in a groove on the first bristle carrier 411a or its pivot pin 413a, e.g. via a latch connection. The guide arm 416 runs between the front side and the rear side of the head part 6.21, within the brush body 5.21.

(241) The coupling mechanism 415 is designed and connected to the bristle carriers 411, 411b such that a translatory movement of the second bristle carrier 411b is transmitted onto the guide arm 416 and accordingly onto the angled arm section.

(242) The first bristle carrier 411a is then brought into a part-peripheral rotation movement via the bent arm section. The effect of the coupling mechanism 415 is such that the first bristle carrier 411a simultaneously executes a rotation movement given a translatory movement of the second bristle carrier 411b.

(243) According to the embodiment variant according to FIGS. 20a-20k and 21a-21k, individual functional elements, in particular cleaning bristles 377, 477 are arranged laterally on the head part 6.20, 6.21, in the region of the second bristle carrier 311b, 411b. The functional elements, in particular bristles 377, 477 are connected to the head part 6.20, 6.21 via a holding section 375, 475. The holding section 375, 475 at the same time forms a delimitation element 375, 475 for delimiting the translatory movement of the second bristle carrier 311b, 411b.

(244) For this, the second bristle carrier 311b, 411b comprises laterally arranged indentations 376, 476, in which the holding sections 375, 475 of the functional elements 377, 477 are guided with play. The bristle carriers 311b, 411b now can be translatorily displaced in the longitudinal direction L only as far as the indentations 376, 476 have play with respect to the holding sections 375, 475. The play between the indentations 376, 476 and holding sections 375, 475 defines the maximal possible movement path.

(245) With the previously mentioned embodiment examples, it is conceivable for the one bristle carrier or brush head to be actively motorically driven and in this manner to indirectly co-drive the other bristle carrier or brush head. The motoric drive can be electrical.
