Abstract: A foldable head restraint has two head restraint supports set within a bracket. A latch is made integral with at least one of the head restraint supports. The latch rests against a stop to prohibit rotation of the head restraint support in a first direction. The latch rests against a rotational cam to prohibit movement of the head restraint support in a second direction. By rotating the cam, the head restraint support may be folded. The head restraint support is comprised of a metal substrate with over-molded plastic geometry to accept a mating part configured within the head restraint bun. The geometry of the metal substrate and over-molded plastic geometry allow for a reduction, or even elimination, of the slots that are normally required for such a folding head restraint. This ability to fold can yield greater rearward visibility and aid in the kinematic motion of the seat.

Abstract: A vehicle seat device includes a seat cushion frame and a seatback frame including a lower-side frame supported at a lower end portion thereof to be tiltable relative to a rear end portion of the seat cushion frame, an upper-side frame arranged at an upper portion of the lower-side frame, and a center bending mechanism coupling the lower-side frame and the upper-side frame to be bendable forward, wherein the center bending mechanism bends the upper-side frame about a rotational center that is ahead of a seatback outer layer covering a front surface of the seatback frame. The movement of the upper-side frame when tilted comes close to the movement of the passenger who bends forward. The slip between the seatback outer layer and the back of the passenger can be minimized, and thus, it becomes possible to lessen an uncomfortable feeling of a passenger.
