Headrest
The invention relates to a headrest, in particular for a vehicle seat, with a head contact part ( 11 ), with a support ( 12 ) for mounting the headrest ( 10 ) on a fixed structure, with at least one parallelogrammatic linkage ( 23 ) between the head contact part ( 11 ) and the support ( 12 ) that carries the head contact part ( 11 ) for movement relative to the support ( 12 ) between a first position and a second position, wherein the parallelogrammatic linkage ( 23 ) comprises at least two links ( 16, 17 ), and each link ( 16, 17 ) forms at least one pivot joint (G 1 A, G 2 A, G 1 C, G 2 C) with the support ( 12 ) and at least one pivot joint (G 1 B, G 2 B, G 1 D, G 2 D) with the head contact part ( 11 ), with a latch ( 19 ), with a first latch formation on the support ( 12 ) and a second latch formation on the head contact part ( 11 ), wherein the first latch formation and the second latch formation are in engagement in a locked position and are disengaged in a release position. The special feature is that the first latch formation is fixed on the support ( 12 ) or that an upper region of at least one link ( 116 ) is provided with the first latch formation, and that the second latch formation is fixed on the head contact part ( 11 ).
1. A headrest comprising:
a head contact part;
a support carrying the head contact part on a fixed structure;
at least one linkage between the head contact part and the support and carrying the head contact part for movement horizontally relative to the support between a first position and a second position horizontally offset therefrom, the linkage including at least two links that each form at least one pivot joint with the support and at least one pivot joint with the head contact part;
a latch including a pair of first latch formations fixed on and projecting upward from the support and respective second latch formations secured on the head contact part between and juxtaposed with the respective first latch formations and each movable relative to the respective second latch formation between
a locked position engaged with the respective second latch formation and blocking relative movement of the head contact part relative to the support between the first and second positions and
a release position disengaged from the respective second latch formation and allowing such relative movement of the head contact part relative to the support; and
an actuation element on the head contact part displaceable to displace the second lock formations between the respective locked positions and the respective release positions.
2. The headrest according to claim 1 , wherein the support comprises at least one support bar or support bar bracket.
3. The headrest according to claim 1 , wherein the second latch formation comprises at least one lock element displaceable between the locked position and the release position.
4. The headrest according claim 3 , wherein the at least one lock element is formed by a toothed rack that is provided with at least one recess.
5. The headrest according to claim 4 , wherein the toothed rack structure is displaceable essentially horizontally between the locked position and the release position.
6. The headrest according to claim 5 , wherein the support comprises two projections, and two parallel respective toothed racks are provided.
7. The headrest according to claim claim 6 , wherein the toothed racks are adjacent the pivot joints of the linkage on the side of the head contact part.
8. The headrest according to claim 1 , wherein the head contact part comprises an adjuster for vertical adjustment of the head contact part or part of the head contact part.
