An adjustment mechanism for a headrest for a seat has a scissor lever. The adjustment mechanism has at least one first lever arm and at least one second lever arm. A compensating lever arm is arranged at at least one lever arm end of each lever arm. A free end of each compensating lever arm has an attachment structure for attaching the compensating lever arm to a body. A lever arm end opposite the compensating lever arm of each lever arm has an attachment structure for attaching the lever arm to a body. A headrest for a vehicle seat, which has a headrest body is also provided.

A headrest position adjusting device for a vehicle, may include a first motor mounted to a seatback frame; a first link connected to the first motor to be rotatable to a predetermined first angle in a leftward-rightward direction; a second motor mounted to the first link; a second link connected to the second motor to be rotatable to a predetermined angle in an upward-downward direction; a third motor mounted to the second link; a third link connected to the third motor to be rotatable with respect to a rotation axis of the third motor; and a headrest frame connected to the third link and mounted in a headrest pad.

A rear-center head restraint system of an automobile vehicle includes a rear seatback of the automobile vehicle. A head restraint assembly is rotatably mounted to the rear seatback and is moved between a stowed position and an in-use position. The head restraint assembly includes a rear head restraint body defining an L-shape and includes a forward-facing surface moved toward a head of an occupant at the in-use position. At least a first link and a second link are rotatably connected to the seatback. The first link and the second link are also rotatably connected to the rear head restraint body. A release system rotates the head restraint assembly selectively between the stowed position and the in-use position.

A method of assembling a vehicle seat is provided, comprising: providing a seat back frame; forwardly movably connecting a headrest for supporting a head of a seat occupant to the seat back frame; mounting a rear-end collision detector to the seat back frame at a position behind the seat occupant, operatively connecting the rear-end collision detector to the headrest; disposing a link member at a position lateral to the rear-end collision detector; forming a front extending portion that inwardly extends in a right-to-left direction at a front end of a lateral face of the side frame; and forming a rear extending portion that inwardly extends in the right-to-left direction; wherein a protruding portion is formed from a portion of the lateral face of the side frame that faces at least the part of the bracket, the link support shaft being disposed at a same height as the protruding portion.

The invention relates to a surface structure (10) for a contact surface or support surface (23) of a vehicle equipment part, in particular for a vehicle head restraint (40) or vehicle armrest, the surface structure (10) being elastically deformable, the surface structure (10) comprising at least one surface body (13, 13a, 13b), each surface body (13, 13a, 13b) being connected to at least one other surface body (13, 13a, 13b) and/or to the vehicle equipment part by means of at least one elastically deformable connecting element (16).

A reduced-impact-and-recoil headrest that includes a ratchet mechanism, allowing components to incrementally translate with respect to each other. The reduced-impact-and-recoil headrest includes an exterior housing surface that is deformable, providing cushioning for a vehicle occupant's head. The headrest also includes an interior compartment within the housing, with the ratchet mechanism disposed within the interior compartment. The headrest is configured to decrease the force of a collision experienced by the occupant, thereby decreasing the likelihood and severity of traumatic brain injuries resulting from the occupant's head striking a stationary headrest. Instead, the reduced-impact-and-recoil headrest is configured to incrementally move with the occupant's head, providing an incremental cushion for the occupant's head. The ratchet mechanism also prevents the reduced-impact-and-recoil headrest from automatically translating back to its pre-impact position, thereby decreasing the occupant's risk of ligament tear and whiplash.
