The present invention relates to a head rest arrangement for a vehicle seat and a vehicle seat comprising such head rest. The head rest arrangement comprises a cushion portion and a back portion. The head rest arrangement further comprises a displacement arrangement enabling at least the cushion portion to be displaced between at least a first position and a second position with respect to the vehicle seat after being mounted thereto. The displacement arrangement comprising a lock mechanism adapted to lock the cushion portion in the first position and the second position. The displacement arrangement comprises an actuator operable by a user to unlock the lock mechanism. The actuator is made from a compliant material and actuated via a pulling force in a first direction.

A vehicle seat includes: a seat cushion; a seatback that is rotatably connected to a seat rear side of the seat cushion; a headrest that is provided at a seat upper side end portion of the seatback, and that is configured to support a head portion of a vehicle occupant; and a hardness changing section that changes a hardness of a seat front side of the headrest by compressing a pad at an interior of the headrest, in a case in which an angle of inclination of the seatback with respect to the seat cushion is smaller than a predetermined angle, and canceling a compressed state of the pad, in a case in which the angle of inclination is larger than the predetermined angle.

Arrangements for safety and comfort in vehicles.

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.

A vehicle seat for use in a vehicle comprises a seat body for engagement with a seated occupant's body. The seat body including: a seat base for receiving a seated occupant and a backrest extending upward from the base for supporting the seated occupant's back, and a headrest connected with the backrest and projecting upward from the backrest. The headrest includes a receiving face facing forward for engagement with the occupant's head in the event of a sudden change in velocity to ease rearward movement of the occupant's head.

A seat headrest assembly (16) includes a core (54) that includes a core bottom (56). A thermal conditioning device (22) includes a housing (26) that provides a fluid passage (28) that extends to a vent (62). A heating module (36) and a blower (38) are arranged in the fluid passage. The thermal conditioning device is arranged beneath the core bottom.
