[0037] Parts which correspond to one another are denoted by the same reference signs in all the figures.

[0038] A vehicle seat S illustrated schematically in FIG. 1 will be described below using three spatial directions which are perpendicular to one another. In the case of a vehicle seat S installed in the vehicle, a longitudinal direction x is substantially horizontal and preferably parallel to a vehicle longitudinal direction, which corresponds to the normal direction of travel of the vehicle. A transverse direction y perpendicular to the longitudinal direction x is likewise oriented horizontally in the vehicle and is parallel to a vehicle transverse direction. A vertical direction z is perpendicular to the longitudinal direction x and perpendicular to the transverse direction y. In the case of a vehicle seat S installed in the vehicle, the vertical direction z is preferably parallel to a vehicle vertical axis.

[0039] The positional indications and directional indications used, such as for example front, rear, top and bottom, relate to a viewing direction of an occupant seated in the vehicle seat S in a normal seating position, wherein the vehicle seat S is installed in the vehicle, is in a use position suitable for conveying passengers, with an upright backrest 11, and is oriented in the conventional manner in the direction of travel. The vehicle seat S according to the invention may however also be installed in a different orientation, for example transversely to the direction of travel.

[0040] The vehicle seat S has the backrest 11 and a seat part 12. A headrest 1 according to the invention is arranged on the backrest 11. FIG. 2 schematically shows, in a perspective view, the headrest 1 with a height-adjustable headrest body 2.

[0041] The headrest body 2 may be produced from natural materials or from a plastic material or from a combination of the two. The headrest body 2 is arranged on a supporting element 3. The supporting element 3 is in turn able to be arranged on, preferably able to be to, the vehicle seat S. FIG. 2 shows two rod ends 3.1 of the supporting element 3, which serve for fastening the height-adjustable headrest 1 to the vehicle seat S.

[0042] For the purpose of height adjustment of the headrest body 2 relative to the supporting element 3, an actuation element 4 is arranged on the headrest body 2, through the actuation of which actuation element an arresting action of the headrest body 2 in a height position HP is able to be released, whereby the headrest body 2 is freely movable, and thus height-displaceable, upward or downward (in the present case substantially in and counter to the vertical direction z). By way of the wording “substantially parallel to the vertical direction z”, angular deviations in relation to the vertical direction z, which result in particular from a comfort-angle setting of the backrest 11, are also intended to be included. Said angular deviations may be up to 30 degrees in relation to the vertical direction z.

[0043] The headrest body 2 is, in particular substantially parallel to the vertical direction z, height-adjustable in a stepped manner and able to be selectively releasably arrested in one of multiple height positions HP. The height positions of the stepping are a lower height position HP1, an upper height position HP2 and multiple height positions HP arranged between the lower height position HP1 and the upper height position HP2. FIG. 3A shows the headrest 1, wherein the headrest body 2 is arrested in a height position HP1, which is a lower height position relative to the supporting element 3. FIG. 3B shows the headrest body 2 in a height position HP2, which is an upper height position relative to the supporting element 3.

[0044] FIG. 4 shows the exemplary embodiment of the headrest 1 in an exploded illustration. The headrest 1 comprises a base supporting element 5, and a holding element 6 which is arranged therein and is able to be guided so as to be height-displaceable in particular substantially parallel to the vertical direction z. The holding element 6 is in this case arranged so as to be movable, in particular height-movable, in particular height-displaceable, in the base supporting element 5 and thus relative to the base supporting element 5. Furthermore, the holding element 6 is arranged or mounted on the base supporting element 5 so as to be height-movable, in particular height-displaceable, relative to the supporting element 3.

[0045] The supporting element 3 is in the form of a U-shaped supporting bracket in the exemplary embodiment. Alternatively, the supporting element 3 may be in the form of a pair of supporting rods. The supporting element 3 may be formed from a plastic material or from a metal or from a metal alloy.

[0046] The base supporting element 5 is formed from a plastic material, in particular a high-strength plastic material. The base supporting element 5 is fastened to, in particular held in a form-fitting and/or force-fitting manner on, the at least one supporting element 3. The base supporting element 5 is consequently connected fixedly to the supporting element 3. Consequently, the height positions HP, HP1, HP2 relate to the base supporting element 5 too.

[0047] The holding element 6 serves for receiving and securing the headrest body 2 on the base supporting element 5. The holding element 6 engages for example through the base supporting element 5 or extends through the latter and is connected to the headrest body 2 on both sides of the base supporting element 5.

[0048] The headrest body 2 is formed from two connectable headrest sub-elements, in particular two headrest shells 2.1 and 2.2. In the present case, a front headrest shell 2.1 is arranged substantially in front of the base supporting element 5 and a rear headrest shell 2.2 is arranged substantially behind the base supporting element 5.

[0049] The holding element 6 is manually height-adjustable, in particular height-displaceable, in relation to the base supporting element 5. The holding element 6 is configured to hold the headrest body 2 and, during a height adjustment, to guide the latter. For this purpose, the holding element 6 comprises a number of connecting elements, which at the same time are guiding parts, in the present case two pins 6.1. The pins 6.1 are in the form of combined connecting pins, holding pins and guiding pins. The two headrest shells 2.1 and 2.2 are connected fixedly to one another by the two pins 6.1. The headrest shells 2.1 and 2.2 are moreover guided so as to be height-adjustable relative to the base supporting element 5, and held in a releasably arrestable manner in one of the set height positions HP, HP1, HP2, by the two pins 6.1. The pins 6.1 are oriented substantially parallel to the longitudinal direction x. By way of the wording “substantially parallel to the longitudinal direction x”, angular deviations in relation to the longitudinal direction x of up to 30 degrees are intended to be included.

[0050] Additionally, the headrest shells 2.1 and 2.2 may have mutually corresponding fastening means 2.4, for example clips and clip openings, by which the headrest shells 2.1 and 2.2 are able to be releasably connected to one another.

[0051] For the purpose of forming a means for guiding and arresting the headrest body 2 in one of the height positions HP, HP1, HP2, the base supporting element 5 comprises a number of openings 5.1 into which the holding element 6, in particular the pins 6.1, are guided in a height-displaceable manner. The openings 5.1 are for example in the form of passage openings which extend parallel to the vertical direction z, for example elongated holes or passage grooves.

[0052] The number of openings 5.1 corresponds in particular to the number of pins 6.1. The headrest body 2 is thus able to be displaced particularly effectively in the base supporting element 5, in particular substantially parallel to the vertical direction z.

[0053] The headrest 1 furthermore comprises a locking element 7 which is movable relative to the base supporting element 5 between a locked position VP (illustrated in FIGS. 4, 5 and 7) and an unlocked position EP (illustrated in FIG. 6). The headrest body 2 is able to be releasably arrested in a set height position HP, HP1 or HP2 on the base supporting element 5, and thus in relation to the vehicle seat S, by the locking element 7.

[0054] The locking element 7 is for example in the form of a plate-shaped locking element 7 which is movable in the transverse direction y or in the form of a slide. Preferably, the locking element 7 is guided in a movable manner on the base supporting element 5.

[0055] The actuation element 4, in particular an actuation button, is provided for the actuation of the height adjustment of the headrest 1. In the fitted state of the headrest 1, the locking element 7 is coupled in terms of movement to the actuation element 4.

[0056] When the actuation element 4 is actuated, the locking element 7 is moved from the locked position VP (illustrated in FIGS. 4, 5 and 7) into the unlocked position EP (illustrated in FIG. 6), so that the holding element 6, and along therewith the headrest body 2, is freely movable, in particular height-displaceable. When the actuation element 4 is released, or if the latter is not actuated, the locking element 7 is moved automatically, for example by way of spring force, in relation to the base supporting element 5 into the locked position VP and locks the holding element 6, whereby the headrest body 2 is fixed and held at the set height. For transfer of the locking element 7 into the locked position VP, a restoring element 8, in particular a restoring spring, is provided.

[0057] The restoring element 8 is arranged in a receptacle 5.2 of the base supporting element 5. One end of the restoring element 8 is in engagement with the base supporting element 5, and the opposite end of the restoring element 8 is in engagement with the locking element 7. When the actuation element 4 is actuated, and accordingly the locking element 7 is moved into the unlocked position EP, the restoring element 8 is subjected to stressing. When the actuation element 4 is released, the restoring element 8 can be relieved of stressing, whereby the locking element 7 is automatically reset into the locked position VP and the actuation element 4 is reset into its initial position or rest position.

[0058] The actuation element 4 may be in the form of an actuation button which is arranged in a cutout 2.3 of the headrest body 2 and is held so as to be movable relative thereto.

[0059] The headrest shells 2.1 and 2.2 may be provided on the inner side with reinforcement elements 9, in particular ribs and/or webs, such that they run in a longitudinal, crossing and/or transverse manner. The front headrest shell 2.1 has a head-bearing surface on the outer side and is correspondingly upholstered. The rear headrest shell 2.2 is of substantially planar form on the outer side and may comprise at least one receptacle, in particular latching grooves, plug-in receptacles or similar structures, which serve for example for receiving and securing mobile devices.

[0060] FIG. 5 schematically shows, without the headrest body 2, the headrest 1 with the base supporting element 5 and with the locking element 7 in the locked position VP. The actuation element 4 is in its initial position or rest position, a non-actuated position. The locking element 7 is designed in such a way that only one of the pins 6.1 is locked. Said pin 6.1 is in the form of a combined connecting means, guiding means and locking means that is both guided in an associated opening 5.1 so as to be height-displaceable during a height adjustment and able to be releasably arrested in a set height position HP, HP1, HP2, and that moreover connects the two headrest shells 2.1 and 2.2 to one another. The other pin 6.1 is only guided in an associated opening 5.1, and is not releasably arrestable.

[0061] The locking element 7 comprises a plurality of locking receptacles 7.1, which correspond to different height positions HP, HP1, HP2, wherein one pin 6.1 is able to be arranged in a releasably arrestable manner in one of said locking receptacles 7.1 according to the selected height positions HP, HP1, HP2.

[0062] In the present case, the locking element 7 is in the form of a locking plate which is adjustable between the locked position VP and the unlocked position EP, wherein, in the unlocked position EP, the headrest body 2 is freely movable, in particular height-displaceable, and, in the locked position VP, the movement of the headrest body 2, in particular upward and downward, is arrested.

[0063] In the locked position VP, the restoring element 8 is in a state relieved of stressing, wherein the locking element 7 is held in the locked position VP and the actuation element 4 is held in its initial position or non-actuated position.

[0064] FIG. 6 shows the locking element 7 in the unlocked position EP, in which the pins 6.1 are guided in the openings 5.1 so as to be freely movable upward and downward. The restoring element 8 is in a state subjected to stressing. FIG. 7 shows the locking element 7 in the locked position VP. FIG. 8 shows the headrest body 2 in the lower height position HP1. FIG. 9 shows the headrest body 2 in the upper height position HP2.

[0065] The holding element 6 is configured to hold the headrest body 2 in a height-adjustable manner. For example, the two pins 6.1 connect the two body shells 2.1, 2.2 fixedly to one another.

[0066] The features which are disclosed in the above description, in the claims and in the figures can be of significance both individually and in combination for the realization of the invention in its various configurations, insofar as they remain within the scope of protection of the claims.
