[0168] In the following description, the same reference numerals are used for identical and similarly acting parts.

[0169] FIG. 1 shows a child seat according to the invent according to ion with side impact protector in the rest position.

[0170] The child seat 10 comprises a seat shell 50 attached to a base 20, and an impact shield 90 (both base and impact shield are optional). In other embodiments, it is also possible that parts of the base co-form the seat shell. Here, the base 20 comprises (optionally) a (telescopic) support leg 30 and (also optionally) Isofix latches 40 serving as anchorage.

[0171] The seat shell 50 comprises a seat section 60 as well as a back section 70 with a headrest 80, the seat section 60 defining a seating 61 and first side areas 62, and the back section 70 defining a (back) support surface 71 (for laying-on the child's back) and second side areas 72. The headrest 80 also has side areas not specified here and a head support surface.

[0172] The seating 61, the support surface 71 as well as the inner sides of the first side areas 62 and second side areas 72 facing a child accommodated in the child seat are part of an inner side 52 of the seat shell 50, which (at least in sections) defines a receptacle space 51 for the child. The sides of the seat shell facing away from a child accommodated in the child seat, in particular the outer sides of the first side areas 62 and second side areas 72, are part of an outer side 53 of the seat shell 50.

[0173] On the outer side 53 of the seat shell 50 and according to an embodiment (which is not mandatory) on an outer side of the second side regions 72 a side impact protector 100 is provided. In principle, it would also be possible to provide the side impact protector 100 on an outer side of the first side areas 61 of the seat section 60 or also on an outer side of the side areas of the headrest 80, however, the variant shown here is preferred in the back section 70 (in particular to the rear of the back support surface 71, preferably in relation to the place of attachment in the functional position).

[0174] The dashed line marked with the reference sign 54 schematically represents an area of the inner side 52 of the seat shell in which, according to the embodiment, an actuating element 141 of a first locking device 140 shown in detail below (cf. in particular FIGS. 6a to 9) can be accessible. The area 54 shown in FIG. 1 can correspond to a side element which is not visible in FIG. 1 (since it is provided on the opposite outer side of the seat shell), while the area corresponding to the side element 100 shown is also not shown (but is concealed by the second side areas).

[0175] FIG. 2 shows the child seat shown in FIG. 1 (in sections) in a side view. In particular, it can be seen here that the side impact protector 100 comprises a side element 101.

[0176] FIG. 3 shows an upper section of the child seat shown in FIGS. 1 and 2 in a rear view. In this view, it can be seen that a side impact protector 100 is provided on both the right and the left side of the seat shell 50 (in principle, a side impact protector 100 can also be provided on only one side or on at least one side, or possibly both sides, several side impact protectors). Furthermore, one derives from the illustration that in the rest position shown, the side impact protector 100 does not increase a width of the child seat (or at least not significantly, in particularif at allby no more than e.g. 2 cm).

[0177] FIG. 4 shows a part of the seat shell of a child seat as well as side impact protector according to the invention in rest position.

[0178] The side impact protector 100 is arranged (or attached) in a back section 70 on the outer side 53 of the seat shell 50. It comprises a side element 101, the distal end 105 of which can be moved (or pushed) towards the receptacle area 51 or the seat shell 50 when the side impact protector is in its rest position, in order to release a first locking device 140 explained in detail below and allow a transfer of the side impact protector to the functional position.

[0179] In FIGS. 5a, 5b, a part of the seat shell of a child seat and side impact protector according to the invention (corresponding to FIG. 4) is shown in the functional position.

[0180] When the side impact protector 100 (in particular its side element 101) is transferred into the functional position, a recess 55 is visible in the outer side 53 of the seat shell, in which the side element is accommodated at least in sections (possibly at least substantially completely in the rest position) and/or only partially in the functional position (for example over at least 20%, possibly at least 30% and/or at most 50%, possibly at most 40% of its length). In the functional position, the proximal end 104 of the side element 101 is closer to the receptacle space 51 or a seat shell 50 than the distal end 105 of the side element 101.

[0181] FIG. 6a shows an interior view of a section of the seat shell (without padding/fabric cover). FIG. 6b shows an exploded view of the side impact protector and a section of the seat shell.

[0182] The side element 101 can have an upper shell 102 and a lower shell 103 (but not necessarily). In other embodiments, however, it may be assembled in other ways or in one-piece, in particular the side that is not visible in the rest position may be open or open in sections. The side element 101 is mounted on the seat shell 50 via an axis 106, wherein, according to embodiments, the seat shell 50 comprises an element (co-) forming the recess 55, which can also form a support section 56 for the side element. The seat shell 50 can have (in particular in the region of the element forming the recess 55) a through hole 57 for the passage of the latch 143 of a first locking device. Furthermore, the seat shell may comprise a clamp 58 (possibly particularly stable, e.g. made of metal) in which the axle 106 is mounted.

[0183] The side element 101 is furthermore connected to the seat shell 50 (here optionally: with the clamp 58) via a spring. On the one hand, this spring serves as a position transfer device 120 (or component thereof) and urges the side element 101 from the functional position or an intermediate position into the functional position. On the other hand, the spring also forms a second resilient element 161 which, as part of a second locking device 160, enables a locking of the functional position.

[0184] The first locking device 140 serves to lock the rest position of the side impact protector 100 (in rest position) and is transferable between a locking position and a non-locking position. However, the mere transfer of the side element 101 or the side impact protector 100 into the rest position does not (alone) trigger any locking. This is because the first locking device 140 comprises a first resilient element 142 which biases the first locking device 140 towards the non-locking position. To achieve locking of the side impact protector 100 in its rest position (and thereby prevent the position transfer device 120 from transferring the side element 101 to the functional position), actuation of an actuating element (or, more generally, a first actuating device) 141 is provided, whereby a latch 143 is moved in or through the through hole 57 of the seat shell. At the end of the latch 143 is a hook 144, which can cooperate with an engagement structure 107 of the side impact protector 100 (as further detailed below with further optional details). Actuating element (first actuating device) 141 and latch 143 as well as hook 144 may be formed as different (separate) elements or combined, possibly in one piece.

[0185] FIG. 7 shows a sectional view of the side impact protector in rest position as well as a part of the seat shell.

[0186] The side impact protector is in its locked rest position. For this purpose, the latch 143 (namely, in the optional embodiment, the hook 144 of the first locking device 140) is in engagement with the engagement structure 107 at the proximal end 104 of the side element 101. The engagement of the hook 144 with the engagement structure 107 prevents the transfer of the first locking device 140 to its non-locking position against the force of the first resilient element 142 (in this case: a compression spring, but this is not mandatory). The latch 143 prevents against the force of the position transfer device 120 the transfer of the side element 101 into the functional position when the first locking device 140 is in the locking position.

[0187] The position transfer device 120 (optional here: tension spring) connects the side element 101 to the (optional) clamp 58 (or another part of the child seat or seat shell) and is under tension. Here, the distal end 105 of the side element 101 only approximately (but not entirely, but which may be the case in alternative embodiments) abuts to the seat shell 50 (or the recess 55 of the seat shell 50) and protrudes slightly therefrom.

[0188] Preferably, the side element can be moved even further in the direction of the seat shell, so that it possibly abuts fully (or at least abuts even closer to the seat shell). During such a further movement (possible according to the embodiment), however, (preferably) no point of the side element should describe a path which (in relation to a straight connecting line between the starting and end point of the movement) is greater than 2 cm, preferably greater than 1 cm. Optionally, the point describing the largest path may describe a path of at least 1 mm, optionally at least 2 mm.

[0189] The side element 101 may comprise an oblong hole 163 (at least according to an embodiment, although this is not mandatory) which extends (at least approximately) in the direction of an (imaginary) connection of the proximal end 104 and the distal end 105, and in which the axle 106 is guided.

[0190] The underside of the latch 143 may have a run-up slope, so that if the first locking device 160 is in the locking position (for whatever reason) while the side impact protector 100 is in the functional position, a transfer of the side impact protector 100 from the functional position to the rest position also results in a transfer of the first locking device 160 to the non-locking position by forcing the latch 144 into the through hole 57.

[0191] FIG. 8 shows a sectional view of the side impact protector as well as a part of the seat shell according to FIG. 7, but in a maximally folded position beyond the (locked or lockable) rest position.

[0192] The side impact protector 100 is in the maximum folded position, which can be achieved for example by pressing the release actuating element (release actuating device), namely the distal end 105 of the side element 101 (in the direction of the seat shell or receptacle space 51), against the force of the position transfer device 120. As a result, the position transfer device is in a maximum tensioned state and the engagement structure 107 has moved away from the latch 143 and the hook 144, so that the first locking device 140 has been transferred to the non-locking position by the bias of the first resilient element 142. The axle is held (cf. also FIG. 7) closer to the proximal end 104 of the oblong hole 164, and the side element 101 now abuts with its distal end 105 (at least partially) to the seat shell 50.

[0193] FIG. 9 shows a sectional view of the side impact protector as well as of a part of the seat shell according to FIGS. 7 and 8, but in the functional position.

[0194] The side impact protector 100 is in its locked functional position. To achieve this, the bias of the position transfer device 120 has caused the proximal end 104 of the side element 101 to pivot towards the receptacle space 51 or seat shell 50. At the same time, the distal end 105 of the position transfer device 120 was pivoted away from the receptacle space 51 or the seat shell 50 and now protrudes laterally from the seat shell. After the (at least almost) complete pivoting of the side element, the remaining bias of the spring, now in the function as second resilient means 161 and part of a second locking device 160, has pulled the side element 101 towards the receptacle space 51, so that the proximal end 104 (or sections thereof) comes to rest between a first stop 59 and a second stop 162.

[0195] In this case, the guidance of the movement is done by the oblong hole 163 and the axle 106, which at the end of the movement is mounted closer to the distal end 105 of the oblong hole 163. In the example shown, the second stop 162 is formed by an edge of the clamp 58 and limits the unfolding of the side element 101. In the example shown, the first stop 59 is formed by an edge of the element forming the return 55 and prevents the side element 101 from folding back or collapsing back into the rest position. The functional position of the side impact protector 100 is locked by these two stops 59 and 162 and the second resilient element 161. After reaching the locked functional position of the side element, the position transfer device 120 or the second resilient element is relaxed (or at least less biased than in the rest position of the side element). The locking can be released again by pulling at the side element (or a part of the side element) away from the receptacle space 51 or the seat shell 50.

[0196] FIG. 10 schematically shows three different positions of an alternative embodiment of a side impact protector 100 with a section of the seat shell.

[0197] Here too, the side impact protector 100 comprises (or is formed from) a side element 101. The side element 101 is designed to be foldable analogous to the previous embodiments. However, the folded rest position shown (in FIG. 10, centre) cannot be locked by folding alone, but only (see FIG. 10, bottom) by a displacement of the folding element so that a distal end 105 of the side element 101 comes to lie under an undercut 170 of the seat shell 50. Also in this embodiment, the side element can be biased in such a way that it (without locking) is automatically transferred into the functional position (not shown in detail), e.g. by a torsion spring in the area of the axis of rotation. For example, the folding axis can be guided in or on (not shown) rails (e.g. oblong holes) of the seat shell 50 to enable a displacement of the side element 101.

[0198] Alternatively, a displacement of the folding element in another direction along the surface of the seat shell may be enabled, the undercut being provided for this purpose in the respective direction. Furthermore, preferably in contrast to the variant shown above in the aforementioned design with undercut as well as the alternative designs, the axis of rotation can be fixed in relation to the seat shell, in which case, for example, an oblong hole in the side element enables the displacement behind the undercut.

[0199] FIG. 11 shows a further embodiment of a side impact protector or side element 101 according to the invention. The side element 101 comprises a lower part 103 (or inner part), which can (at least in sections) abut against the seat shell 50 (possibly at a distance of at most 2 cm or at most 0.5 cm or directly) and which can be fastened to the seat shell 50. Further, the side element 101 comprises an upper part 102 (or outer part) configured to protrude from the seat shell (at least in a functional position) and to be contacted by a laterally arranged external surface (e.g. motor vehicle surface, for example inner surface of a motor vehicle door) (at least in the event of an accident, possibly also beforehand in normal use). Lower part 103 and upper part 102 may be detachably or non-detachably connected to each other. A one-piece (possibly monolithic) or multi-part (many-part) design of the respective part and/or parts 102, 103 together is possible. In particular, the parts 103, 102 can form a common part or merge into one another.

[0200] A first engagement structure (engagement element) 108 is provided at a first end 104 of the side element 101 (specifically, but not necessarily, of the inner or lower part 103), which can engage with a corresponding counter structure of the seat shell 50. Specifically, the first engagement structure 108 here protrudes from the lower part 103 of the side element 101 (according to an embodiment, in a direction pointing away from the second end 105 as well as the upper (outer) part 102). A corresponding angle may, for example, be at least 10 or at least 20 and/or at most 70 or at most 60 or at most 30 with respect to an inner side of the side element 101.

[0201] When the first engagement structure 108 is in engagement with the counter structure of the seat shell 50, it has a retaining (but not necessarily a locking) function. For this reason, the first engagement structure 108 is made preferably (at least comparatively) rigid. At a second end 105 of the side element 101 (specifically a corresponding end of the inner or lower part 103), a second engagement structure (engagement element) 109 is protruding, which can engage in a corresponding counter structure (e.g. receptacle) of the seat shell 50.

[0202] The second engagement structure 109 preferably points (at least substantially) in the same direction as the first engagement structure 108, in particular in such a way that both engagement parts 108, 109 (together) predefine (or define) a movement for attaching (fitting) and removing (detaching) the side element 101. The second engagement structure 109 may comprise a latching device (latching nose) 1091. The mode of operation of the second engagement structure (the second engagement element) will be explained further below.

[0203] The first end 104 in the embodiment according to FIG. 10 may be a rear end. The second end 105 may be a front end (cf. also the last figure showing a corresponding child seat with the side element 101 according to FIG. 11).

[0204] FIG. 12 shows the side element 101 according to FIG. 11 in a view from the inside (from the direction of the seat shell 50). In this view, the lower (inner) part 103 is (at least substantially) visible. It can be seen that the lower (inner) part 103 (which is, however, optional) is detachably connected (e.g. by means of screws) at respective attachment points of the engagement structures 108, 109 to the upper part 102. The second engagement structure 109 has a central section 1092, which in turn comprises (according to embodiment, two) arms 1093 and an actuating section 1094 (as part of an actuating device or forming it). The arms 1093 (or generally the central section 1092) are flexible (and in particular resilient) at least in sections, so that by moving (pressing) the actuating section 1094 towards the outer part or upper part 102, the central section 1092 (central part) acts as (or forms) a leaf spring. Adjacent to the arms 1093 (and optionally extending in the same direction), the second engagement structure 109 further comprises optional lateral parts 1095 which are preferably comparatively rigid (at least in the direction in which the central portion 1092 can be bent). The arms 1093 are preferably located between the lateral parts 1095. Furthermore (according to an embodiment even further out), optional auxiliary elements (generally auxiliary structures) 1096 are located (preferably approximately at the level of the actuation section 1094), which can also engage in corresponding counter structures (e.g. recesses) of the seat shell 50 and can (retainingly) support a fastening of the side element 101 in the seat shell 50.

[0205] The auxiliary elements 1096 may be formed as a protrusion or comprise at least one such protrusion (or alternatively or additionally comprise a recess or be formed by such a recess). By means of such auxiliary elements, a safe and reliable positioning can be achieved in a simple manner.

[0206] FIG. 13 shows a section of the seat shell 50 for receiving the side element 101 in an external view. The seat shell 50 has a receptacle area (recess) 51 to which the lower part 103 of the side element 101 can be attached. A second (in particular front) section 511 has an (optional) frame (ornamental frame) and a first receptacle (counter structure) 512 for the first engagement structure 108. A first (in particular rear) section 513 of the receptacle area 51 has an optional (preferably round) receptacle 514 for a head of a screw dome as well as (directly adjacent thereto) a second receptacle (counter structure) 515 for the second engagement structure (the second engagement element), namely in particular for the central section (part) 1092 and the two lateral parts 1095. Further outwardly relative to the second receptacle 515, auxiliary receptacles (counter structures) 516 are also provided for the (two) auxiliary structures (auxiliary elements) 1096. A latching edge, which can be (latchingly) engaged by the latching nose already mentioned above, can be seen in FIG. 14.

[0207] FIG. 14 shows a section of the seat shell for receiving the side element 101 in a view from the outside (in an oblique direction, in particular from obliquely behind).

[0208] The elements and structures shown correspond (at least substantially) to those of FIG. 13.

[0209] FIG. 15 shows a section of the seat shell 50 for receiving the side element 101 with the attached side element 101 in an external view.

[0210] FIG. 16 shows a section of the seat shell 50 for receiving the side element 101 with the attached side element 101 in a view from the outside (in an oblique direction, in particular from an oblique front).

[0211] FIG. 17 shows a view from the inside (i.e. from the area for receiving the child) of a side area 72 of a back section 70 (without covers or softgoods, which may, however, be, or in particular are, provided). The second side area 72 (side panel) has an (outer) rigid shell (hard plastic shell, not to be seen), the inside of which may be covered by a (hard) foam part. An opening (through-hole) 721 may be provided in the second side area (the side panel) 72, in particular in the (hard) foam part, which opening (through-hole) is (at least) large enough for a human finger to fit through it or to accommodate (in cross-section) a circle which can accommodate a diameter of at least 1 cm or at least 1.5 cm and/or at most 8 cm or at most 4 cm (in relation to the upper limits indicated, this is intended to mean in particular that no larger circle than that in the upper limit indicated can be accommodated). The opening 721 lies opposite to the second receptacle 515 of the receptacle area 51. Thus, with the side member 101 attached (plugged on), the actuation section 1094 of the (preferably central) section 1092 of the second engagement structure (engagement element) 109 can be actuated by a (human) finger through the opening 721 in order to disengage the latching device (latching nose) from the counter structure (latching edge) and allow a removal (detaching) of the side member 101 from the seat shell 50.

[0212] FIG. 18 shows the opening 721 in an enlarged view (without side element 101). A section of the second receptacle 515, in particular its latching edge, can be seen in the opening 721.

[0213] FIG. 19 shows an enlargement of the opening 721 (with side element 101). A section of the second receptacle 515 (in particular its latching edge) can be seen in the opening 721. Furthermore, the actuating section 1094 of the central section (central part) 1092 of the second engagement structure (second engagement element) 109 is visible. Furthermore, the latching nose is in engagement with the latching edge.

[0214] FIG. 20 shows a view analogous to FIG. 17, though with softgoods shown but only partially removed (folded away).

[0215] FIG. 21 shows a section of a side wall (in particular an outer shell, preferably a plastic shell or hard plastic shell) of the seat shell or child seat. In particular, the receptacle area 51 can be seen here without the attached (fitted) side element 101. The construction shown in FIG. 21 can (in principle) be designed as explained in FIGS. 11-20.

[0216] FIG. 22 shows a (roughly) horizontal section through the elements and structures shown in FIG. 21, but here including side element 101, namely (roughly) through a centre of side element 101.

[0217] FIG. 23 shows a side view of the side element 101 (similar to FIG. 12, but with slight perspective).

[0218] FIG. 24 shows a view similar to that in FIG. 14 (where a viewing angle is chosen such that one can look into the first 512 and second 515 receptacles.

[0219] FIG. 25 shows an exploded view of a section of the outer side wall (hard plastic shell) of the child seat or seat shell as well as the side element 101 separated into a lower 103 and upper 102.

[0220] Overall, FIGS. 21-25 show basically the embodiment as explained in FIGS. 11-20, with further design (but optional) details.

[0221] FIG. 26 shows a schematic sectional view through a section of the wall of a seat shell 50 with foldable side element 101 according to a further embodiment. Here, the side element 101 is possibly not be arranged behind an indicated back support surface 71, but could be arranged behind it. An actuating device 180 is provided which is accessible from the inner side 52. The actuating device 180 can have or form a button (e.g. push button). The actuating device 180 is spring-mounted here (according to embodiment) and has a pin 181 which engages in a sliding block 182 of a latching element 183. The actuating device 180 is preferably movable (displaceable) in the lateral direction. For this purpose, the sliding block 182 is oriented accordingly (namely obliquely, for example at a 45 angle to an actuating direction), so that a (forced) movement in a direction (at least approximately) perpendicular to the lateral direction or direction of movement of the actuating device results for the locking element 183.

[0222] FIG. 27 shows the actuating device 180 in a (roughly half) pushed-in or pressed-in position, so that the latching element 183 has begun to move from a latched position (according to FIG. 26) to an unlatched position (cf. FIG. 28). Corresponding springs are visible (about halfway).

[0223] FIG. 28 shows the actuating device 180 (fully) pushed-in or pressed-in (generally in an end position) and the latching element 183 in an unlatched position. The side element 101 has been moved from a functional position (FIG. 26) to a rest position. An inner part 103 or inner side (or other inwardly directed structure) of the side element 101 prevents the latching element 103 and the actuating device 180 from moving back to the initial position, so that the at least one spring (the two springs) remains (remain) biased. The embodiment according to FIGS. 26-28 can be combined with a position transfer device (not shown here), wherein the position transfer device is designed to transfer the side element 101 from its functional position to its rest position (and/or vice versa).

[0224] FIG. 29 represents an alternative embodiment to those in FIGS. 26-28. This embodiment can basically be executed as explained in FIGS. 26-28, but can have the following differences (each optional in itself). Firstly, the back support surface 71 is here displaced forwards relative to the side element 101 (or the side element 101 is correspondingly displaced backwards), so that the side element 101 is (at least substantially) located behind it (particularly if covers and paddings not yet shown are, as usual, included). Second, a distal end 105 of side element 101 now includes a recess (receptacle) 190 that can receive the latching element 183 when the side element 101 is in the rest position. Thirdly, latching element 183 and receptacle 190 can be designed (e.g. by means of inclined surfaces) in such a way that a rest position of the side element 101 is only maintained if no external force is applied (at least above a predetermined force threshold). If an external force (possibly above a predetermined force threshold) is applied (for example because a user pulls on the side element from the outside), the inclined surfaces can cause the latching element 183 to pull the actuating device 180 (release button) into an engaged position against the force of the at least one spring (of the two springs) and release a transfer of the side element 101 from the rest position to the functional position. This embodiment (according to FIG. 29) can be combined with a position transfer device (not shown), wherein the position transfer device is designed to transfer the side element from its rest position to its functional position (and/or vice versa) so that, for example, only a (slight) pulling is required to overcome the force threshold. To enable (easy) pulling, a suitable engagement option may be provided in the side element 101, for example, an (at least slightly) overhanging end portion (e.g. front portion) may protrude (at least slightly) further from an outer wall of the seat shell 50 at one point.

[0225] FIGS. 30-33 show a latching and releasing mechanism analogous to FIGS. 26-29 (in particular analogous to FIG. 29), but with a differently designed (and arranged or movable) side element 101. Here, the side element 101 can be pulled out (or pushed in), namely (optionally) behind the back support surface 71. According to a further embodiment (not shown in detail), the side element 101 can also be designed (in itself) telescopic, for example with at least two sections that can be displaced in relation to each other or at least three sections that can be displaced in relation to each other. The (extendable) side element 101 has a mushroom hat-shaped (mushroom-like) end portion, but this is not mandatory. The mushroom hat-shaped end portion and/or an outer side 53 of the seat shell 50 has/have at least one depression 200 (depressions) for easier gripping behind and extraction of the side element 101, which is also only optional. As in the embodiment example shown in FIGS. 26-29, an embodiment with only one spring and/or with different spring types can alternatively be realised.

[0226] According to FIG. 30, the side element 101 is in the rest position, the locking of which is releasable by exceeding a force threshold (by pulling on the side element). Alternatively, a release can be possible via the actuating device 180 (release button).

[0227] FIG. 31 illustrates that by pulling on the side element 101 (indicated by the arrow), the side element 101 can be moved from its rest position and is transferred to an (non-latched) intermediate position, whereby the latching element 183 has been forced out of the latched position due to its inclined surface and thereby pulls the actuating device (release button) towards the engaged position against a force of the respective spring (in particular the two springs).

[0228] FIG. 32 shows the side element 101 in a first functional position. In this position, it is latched against further extraction only insofar as no (exceeding a force threshold) external (pulling) force is applied. Further pulling out from the outside is therefore possible. In contrast, pushing in towards the rest position is only possible if the actuating device 180 (release button) is actuated. The presence of this position is optionalit is sufficient if a rest position and (only) a functional position are defined.

[0229] FIG. 33 shows the side element 101 in the (fully) extended (end) position. To assume the latched end position (or second functional position), the latching element would have to engage in the corresponding recess of the side element 101. However, this is not shown. Rather, a depressed actuating device 108 (release button) is shown, indicated for the case so that the side element 101 can be pushed in towards its rest position (as long as the release button remains depressed).

[0230] FIG. 34 shows a child seat according to the invention with a side element analogous to FIGS. 11 to 33.

[0231] At this point, it should be noted that all the parts described above, taken individually and in any combination, in particular the details shown in the drawings, are claimed as essential to the invention. Modifications thereof are familiar to the skilled person.

[0232] Furthermore, it is pointed out that the broadest possible scope of protection is sought. In this respect, the invention defined in the claims can also be specified by features which are described with further features (without these further features necessarily being included). It is explicitly pointed out that round brackets and the term in particular/particularly are intended to emphasise the optionality of features in the respective context, which does not mean, conversely, that a feature is to be regarded as mandatory in the corresponding context without such identification.
