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.
