Description

[0023] All disclosed features are in themselves fundamental to the invention. Also included fully in terms of content in the disclosure of the application hereby are the disclosure content of the associated priority documents (copy of the earlier application) as well as of the printed publications cited and of the described devices of the prior art, also for the purpose of including individual or several features of these documents in one or in several claims of the present application.

[0024] There is shown:

[0025] FIG. 1 a depiction in perspective of an equipment part in the form of a headrest with a head contact part with a pivot device in the form of an audio wing, which is arranged in the first position, which is a non-use position,

[0026] FIG. 2 a depiction according to FIG. 1, wherein the pivot device is arranged in the second position, which is a use position,

[0027] FIG. 3 a rear view in perspective of the head contact part, wherein a rear cover is not depicted for reasons of clarity,

[0028] FIG. 4 a side view of the headrest according to FIG. 1,

[0029] FIG. 5 a side view according to FIG. 4, wherein the pivot device is arranged in an intermediate position,

[0030] FIG. 6 a side view according to FIG. 4, wherein the pivot device is arranged in the second position,

[0031] FIG. 7 a sectional view according to section line B-B in FIG. 3,

[0032] FIG. 8 a sectional view, wherein the pivot device is located in an intermediate position,

[0033] FIG. 9 a sectional view following FIG. 7, wherein the pivot device is located in the second position.

[0034] In FIG. 1 an equipment part 10 in the form of a headrest is depicted. A base 12 of the headrest is supported on holding rods 13a and 13b, which can be attached to the backrest of a vehicle seat, which is not depicted. A head contact surface 14 is formed on the base 12.

[0035] In the present exemplary embodiment, the equipment part 10 is provided with pivot devices 11a and 11b, which are formed on opposing side regions 20a and 20b. In FIG. 1, only one pivot device 11b is recognizable. The pivot device 11a is only indicated in FIG. 3. The pivot device 11a nevertheless corresponds to the pivot device 11b substantially described here.

[0036] The pivot devices 11a and 11b comprise an arm 24, which is supported pivotably about a pivot axis a on the base part 12 of the equipment part 10. The arm 24 is pivotable between a first position depicted in FIG. 1 and a second position depicted in FIG. 2. The pivot angle is e.g. approximately 90°.

[0037] The pivot device 11 has audio components, such as e.g. loudspeaker and/or microphone, which are to be moved for an advantageous sound and if applicable an advantageous recording of speech into a position that lies with reference to a direction x1 before the head contact surface 14 of the base part 12. In addition, synchronously with the pivoting movement, a translatory relative movement of the extension part 16 takes place relative to the base part 15 such that the extension part 16 and the base part 15 are located in the first position in a nested arrangement and in the second position in an elongated arrangement.

[0038] In the elongated arrangement, the arm 24 has a length L2. In the nested arrangement, the arm has a shorter length L1 with reference to the elongated arrangement. If the audio functions are not required, the freedom of movement and the view of the seat occupant should not be adversely affected.

[0039] The arm 24 comprises a base part 15 and an extension part 16 that is movable in a translatory manner relative to the base part 15 in the directions p1 and p2. Held on the extension part 16 is a carrier 17, which comprises the audio components in a manner is that is not depicted.

[0040] A guide device 30 has first guide means 25 of the base part 15 and second guide means 26 of the extension part 16. The first guide means 25 interact with the second guide means 26 of the extension part 16 such that the extension part 16 is movable in the directions p1 and p2. The directions p1 and p2 refer to a movement of the extension part 16 relative to the base part 15.

[0041] The guide means 25 and 26 are e.g. designed such that freedom of movement of the extension part 16 relative to the base art 15 only exists in the directions p1 and p2. In the present case, this is a so-called dovetail guide, wherein lateral regions of the guide means 26 are guided in grooves 27 of a guide track of the guide means 25.

[0042] The base part 15 is held on a bracket 18, which is attached to a rotary shaft 19. The rotary shaft 19 can be driven by a drive shaft 28 of a motor 23 (see FIG. 3), which is held on the base part 12. The motor 23 can drive the rotary shaft 19—as in the present exemplary embodiment—e.g. in two different directions of rotation u1 and u2. Alternatively, the direction of rotation can be reversed by means of a transmission interconnected between the bracket 18 and the rotary shaft 19. The motor 23 can also have a transmission to change its initial speed.

[0043] On both side regions 20a and 20b of the base 12, a first support surface 21 in the form of teeth of a gearwheel in each case is connected immovably to the base 12. The teeth of the first support surface 21 mesh with teeth of a toothed rail, which is formed by the second support surface 22. The second support surface 22 is fixedly connected to the extension part 16 or formed integrally with this.

[0044] A movement of the arm 24 about the rotary axis a from the first position according to FIGS. 4 and 7 in the direction u1 causes a movement of the extension part 16 relative to the base part 15 in the direction p1. In the first position, the arm 24 has a length L1.

[0045] When the arm 24 has reached the second position (see FIGS. 6 and 9), the extension part 16 is maximally extended and has the length L2.

[0046] In the present exemplary embodiment, the first position is a vertical position, i.e. a center line m of the base part 15 is arranged approximately vertically. The term “vertical” in the sense of the invention includes the vertical and deviations of the position of the base part of up to 20° from the vertical in both directions of rotation. The first position in the present example is a non-use position.

[0047] In the second position, the base part 15 is pivoted by approximately 90 with regard to the first position. The second position is a horizontal position in the present example, i.e. the center line m of the base part 15 is arranged approximately horizontally. The term “horizontal” in the sense of the invention includes the horizontal and deviations of the position of the base part of up to 20 from the horizontal in both directions of rotation. The second position in the present example is a use position.

[0048] The arm 24 is driven by means of the motor 23 in the reverse direction of rotation in order to rotate it in direction u2 from the second position to the first position. During this movement, the extension part 16 is moved in direction p2 relative to the base part 15.

[0049] It is recognizable in FIGS. 6 to 9 that in all positions of the base part 15, the second support surface 22 of the extension part 16 is arranged between a guide surface 29 of the base part 15 and the first support surface 21 such that the first support surface 21 and the second support surface 22 are always in engagement. Since the first support surface 21 and the second support surface 22 in this exemplary embodiment comprise interacting teeth, e.g. a clearance fit is adequate. In the case that instead of teeth, the first support surface 21 and the second support surface 22 alternatively have friction surfaces, e.g. an oversize fit should be chosen.

[0050] In FIGS. 7 to 9, the positions of FIGS. 4 to 6 are shown, wherein the pivot device 20b is depicted in section. The drive shaft 28 and the rotary shaft 19 are recognizable.

[0051] Alternatively to the exemplary embodiment described here, the equipment part 10 could also have just one pivot device with one arm 24 comprising a base part 15 and an extension part 16.
