Headrest
A head rest is illustrated and described that has a head box ( 11 ) by which at least one support rod ( 12 ) can be secured to a vehicle seat, wherein at least one end of the support rod ( 12 ) is received in a bearing ( 14 ) carried on the head box ( 11 ) or the vehicle seat, wherein the support rod ( 12 ) can be latched releasably to at least one bearing ( 14 ) by a latch ( 15 ) movable between a latching position and a release position, wherein the latch ( 15 ) has at least one notch ( 16 ) that extends over a region of the circumference of the support rod ( 12 ) and has a latch element ( 17 ) carried by the bearing ( 14 ). The special feature is that the latch element ( 17 ) is movably mounted, so that in the latching position, in the event of a relative rotation between the support rod ( 12 ) and the bearing ( 14 ), it is movable out of a starting position into at least one crash position.
1. A headrest comprising:
a head box;
a support rod securing the head box to a vehicle seat and rod having one end;
a bearing receiving the one end and carried on the head box or the vehicle seat;
a latch releasably securing the support rod to the bearing and movable between a latching position and a release position and comprised of at least one notch extending angularly on an outer surface of the support rod and a latch element carried by the bearing and movably mounted so that in the latching position, in the event of a relative rotation between the support rod and the bearing, the latch element is movable out of a starting position into at least one crash position; and
a pivot or guide constraining movement of the latch element to a circular path.
2. The headrest according to claim 1 , wherein the latch element is carried by a movable element held on the bearing so as to be movable along the path between the latching position and the release position.
3. The headrest according to claim 2 , wherein the movable element is urged by a biasing element into the latching position.
4. The headrest according to claim 2 , wherein the movable element is a slide.
5. The headrest according to claim 2 , wherein the latch element has support parts mounted fixedly or movably on the movable element.
