A neck rest for a seat of an automobile has a neck rest body which includes a neck rest cushion and at least two neck rest rods connected with the neck rest body, the neck rest rods being accommodated in the back rest of the seat. Each of the neck rest rod has a support portion attached thereto. The neck rest body includes a housing which has a front wall and a rear wall, the cushion being attached to an outer side of the front wall and the rear wall, with the support portion being located in the housing between the front and the rear walls. The housing is moveable between a basic position and an extended position.
Headrest (150) comprising a fixed part (111), a mobile part (112) opposite the fixed part, first (114) and second (115) connecting rods, each connecting rod comprising two branches, connecting the fixed part to the mobile part and two resilient devices acting on the first and second connecting rods to distance the mobile part from the fixed part. The first and second connecting rods respectively slide on the mobile and fixed parts and a third connecting rod (113) is provided to connect the fixed and mobile parts.

A headrest device includes a fixed base, a movable base disposed forward relative to the fixed base, at least one first link being rotatably supported by a connecting shaft provided between the movable base and the fixed base, at least one second link being supported by the connecting shaft so as to rotate relative to the first link, a connection portion connecting the movable base and the fixed base to be relatively movable by a relative rotation between the first link and the second link, a drive portion relatively rotating the first link and the second link in a direction so as to deploy the movable base away from the fixed base on the basis of a detected result by a rear-end collision detection means, and at least one relative rotation restricting portion provided for restricting a relative rotation between the first link and the second link about the connecting shaft.
A vehicle seat with a headrest for a vehicle is formed from an impact cushion and installed upon a seat back. The headrest is pivoted around a stationary pivotal axle aligned transversely to a longitudinal axis of the vehicle and can be swung from an unused position against the force of a spring into a used position. In the used position, the headrest is held stationary by a toggle linkage, which, within its self-limiting swing zone, acts as a pivoting element between the impact cushion and the pivotal axle.
A headrest adjustment assembly is disclosed for adjusting the position of a headrest relative to a seatback. The headrest adjustment assembly includes a guide disposed in the seat back, at least one holding bar disposed within the guide, the guide and holding bar being configured with sufficient clearance to allow selective relative longitudinal and transverse sliding, the holding bar being fixed to the headrest, and a clamping element mounted to the seat back for selectively applying a transverse force to the holding bar to thereby fix the position of the holding bar within the guide and prevent relative transverse or longitudinal sliding.
