Abstract
The headrest (1) comprises a translation guidance assembly (10) guided along a spindle (2) attached to the seat back and an articulation assembly (20) that is mounted swivelling on the guidance assembly, around an axis (7). A locking member (30) swivels on the guidance assembly (10) around an axis (8) that is parallel to the axis (7), between a locked and an unlocked position. The locking member comprises a pad (31) shaped to press on the spindle (2) in the locked position, and a head (32) that is shaped to lock on a curved section (23), attached to the articulation assembly. In this locked position, that the locking member takes under the effect of inertia after a collision, the headrest can neither pivot backwards nor slide downwards. Application of the headrest is directed to automotive vehicle seats.
