ABSTRACT:
Multiple vehicle seats are disclosed with active head restraint systems that receive an input force from an occupant during an impact by a torso support, which consequently actuates a linkage that translates a head restraint upward and forward to the head of the occupant. In one embodiment, the torso support has a translatable connection with the seatback frame and another translatable connection with the linkage. In another embodiment, a torso support is pivotally connected to a pair of links which are each pivotally connected to the frame. In yet another embodiment, the seatback frame includes a structural wire, which provides pivotal connections for two of the links of the linkage.
