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 head restraint of a vehicle seat includes a base element, at least one connection element positioned on the base element for connecting the base element to a backrest of a vehicle seat, a bearing element having a contact surface for contacting a head of a user of the vehicle seat, and a holding element which can be adjusted along a depth axis relative to the base element. The depth axis is oriented perpendicular to the contact surface. The bearing element is connected to the holding element by a damping device, wherein the damping device damps a movement of the bearing element relative to the holding element.

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.

A headrest is supported by an upper lateral member and a lower lateral member of a seat frame. A headrest stay is inserted through each of guide slots, both of which are formed in both the upper lateral member and the lower lateral member, and an extension wire is hooked on a lower end of the headrest stay. In a rear-collision, a seat back is retreated by a force received from a seated passenger, and a tension of the tension wire is accordingly loosened, which causes the headrest to be tilted forward by an urging force of tilt springs.

A child safety seat includes a seat shell and a buffering part. The seat shell includes a backrest portion and two sidewalls, the backrest portion having a front surface facing forward that is suitable to provide support for a child's back, the two sidewalls being respectively disposed at a left and a right side of the seat shell for restricting sideways movements of a child who sits in the seat shell, one of the two sidewalls having a sidewall portion located in front of the front surface. The buffering part is connected with the seat shell, the buffering part being operable to protrude sideways at an outer side of the sidewall portion.

A headrest apparatus in accordance with this disclosure supports the head and cervical spine during driving and driving events. The headrest apparatus including a headrest, one or more rods extending from the headrest, and a rotation mechanism located in the headrest coupled between the headrest and the plurality of rods. The headrest may include at least a front face, a rear face opposite the front face, a bottom face located between a lower portion of the front face and a lower portion of the rear face, and two side faces located opposite each other between the front face and the rear face. In a first position a profile of the front face may conform to a normal cervical spine curvature of an occupant in a seated position.
