Abstract
A vehicle seat for use with a vehicle. The vehicle seat includes a seatback having a frame, a head restraint arrangement, an impact target arrangement, and a ratchet screw mechanism. The impact target arrangement is attached to the head restraint arrangement and moveably attached to the frame. The ratchet screw mechanism includes a first threaded member and a second threaded member. Upon application of a rearward force on the impact target arrangement, the first threaded member at least partially disengages the second threaded member to allow the head restraint arrangement to move from an initial position to a support position.
