Abstract

A headrest for a seat may have a headrest body, a support element having a rod end, and a base support element. The base support element is connected to the headrest body and the height can be adjusted relative to the support element using same. The headrest may also have a locking element for locking the base support element in an adjusted height position on the support element. The locking element may have a locking region and an actuation region. The locking region extends perpendicular to a transverse extension direction of the base support element and may be detachably blocked in a locked position. The actuation region extends from the base support element in a vertical direction. By actuating the actuation region, the locking region can be moved away from the bearing opening. A seat having a headrest of this type is also provided.

First claim

1 - 15 . (canceled)

16 . A headrest for a vehicle seat, comprising:
one headrest body; one support element having at least one rod end for mounting the headrest body; one main support element having at least one bearing opening through which the rod end is routed, wherein the main support element is connected to the headrest body and conjointly with the latter is height-adjustable relative to the support element; and one locking element for locking the main support element in an adjusted height position on the support element, wherein the locking element has at least one locking region and one activation region, characterized in that the locking region extends so as to be substantially perpendicular to a direction of transverse extent of the main support element; the locking region in a locked position is releasably secured on the bearing opening; the activation region extends from the main support element in a height direction; and the locking region by activating the activation region is movable away from the bearing opening.

17 . The headrest as claimed in claim 16 , wherein the main support element comprises two mutually spaced-apart bearing openings, and the locking element has two locking regions that correspond to the bearing openings.

18 . The headrest as claimed in claim 16 , wherein the locking element is formed from a spring wire.

19 . The headrest as claimed in claim 16 , wherein the at least one locking region and the activation region are integrally configured.

20 . The headrest as claimed in claim 16 , wherein the locking element is integral and bent from a spring wire.

21 . The headrest as claimed in claim 16 , wherein the activation region has a flexible region, which is able to be pretensioned by activating the locking element, and an engagement region for activating the locking element.

22 . The headrest as claimed in claim 21 , wherein one end of the activation region connects the flexible region and the engagement region to one another.

23 . The headrest as claimed in claim 21 , wherein the flexible region and the engagement region in a non-activated state of the activation element are mutually spaced apart and extend so as to be largely mutually parallel.

24 . The headrest as claimed in claim 16 , wherein the at least one locking region is disposed in the region of the bearing opening.

25 . The headrest as claimed in claim 16 , wherein the main support element in the region of the at least one bearing opening has a slot-shaped opening, wherein the at least one locking region in a locked state of the main support element is disposed in the opening and is securely engaged with the support element.

26 . The headrest as claimed in claim 16 , wherein the headrest body comprises an activation element which is coupled to the activation region of the locking element.

27 . The headrest as claimed in claim 26 , wherein the activation element bears on the activation region, or is operatively connected directly or indirectly to the activation region, in such a manner that a movement of the activation region results from a movement of the activation element at least in one direction.

28 . The headrest as claimed in claim 16 , wherein the main support element comprises at least one bearing which is held in the bearing opening of the main support element and by which the headrest body is mounted on the support element so as to be height-adjustable relative to the latter.

29 . The headrest as claimed in claim 16 , wherein the headrest body comprises a holding element which is disposed on the main support element and conjointly with the latter is displaceable in terms of height relative to the support element.

30 . A vehicle seat having at least one backrest and one headrest as claimed in claim 16 , wherein said headrest is disposed on the backrest.
