The present invention provides a headrest that is low-cost but still provides impact mitigation performance, and a vehicle seat having this headrest. A headrest of a vehicle seat includes: a headrest frame that is formed of at least one plate material and is fixed to a seatback frame of the vehicle seat; a pad that covers the headrest frame; and a skin that covers the pad. A contact section is provided at the lower part of the headrest frame, said lower part being located on the seatback-frame side, and the contact section is located closer to the rear surface of the headrest than the upper part of the headrest frame is, said upper part being located on the opposite side to the seatback-frame side.

The invention relates to a headrest comprising a base (13) and a head-support part (16) having a guide assembly (18, 52) connected to the head-support part (16) and is connected to the base (13) that moves the head-support part (16) relative to the base (13) in a direction (x.sub.1) toward the seat occupant's head and in the opposite direction (x.sub.2) between a rear normal position and a frontmost extended position.

A deployable headrest airbag includes an airbag chamber configured to be coupled to a headrest of a vehicle seat. The airbag chamber has a stowed position and a deployed position. In stowed position, the airbag chamber is disposed inside the headrest. In the deployed position, the deployable headrest airbag is disposed outside of the headrest to protect a head and a neck of a vehicle occupant.

A child safety seat includes a seat shell having two sidewalls respectively provided at a left and a right side of the seat shell for restricting sideways movement of a child sitting on the seat shell, the two sidewalls including a first and a second sidewall, a buffering part movably connected with the seat shell, the buffering part being movable between a stowed position retracted toward the first sidewall and a deployed position protruding sideways from the first sidewall, a spring for biasing the buffering part toward the stowed position, and a latching mechanism including a latch carried with the buffering part, the latch being movable between a locking state for locking the buffering part in the deployed position and an unlocking state for unlocking the buffering part so that the buffering part is rotatable relative to the seat shell.

A headrest includes a frame made of metal, the frame includes a base plate supported by a headrest fixing device, and a cover plate disposed on an occupant head side of the base plate. The cover plate includes a cover panel portion, and a cover frame portion extending from an outer circumferential edge of the cover panel portion toward the base plate. The base plate includes a base panel portion, and a base frame portion extending from an outer circumferential edge of the base panel portion toward the cover plate, and fitted into the cover frame portion. A first part of the cover frame portion is joined to the base frame portion, and a remaining second part of the cover frame portion is enjoined to the base frame portion.

A headrest may be fixed relative to a seat or a bank of seats in a vehicle and can provide multiple stages of deformation in response to a collision event. The headrest can include a resilient member that deforms in response to a first force caused by the collision event. The headrest can also include a frame that deforms in a first manner in response to a second force greater than the first force and in a second manner in response to a third force greater than the second force. Such a headrest can provide improved impact mitigation for occupants, regardless of height and/or weight such that occupants ranging from the 5.sup.th to 95.sup.th percentile in height and/or weight are afforded similar impact mitigation despite a fixed headrest structure. In some examples, multiple such headrests may be conjoined.

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.
