Abstract

A vehicle seat for use with a vehicle includes a seatback frame having a first locking element, and a head restraint arrangement movably associated with the seatback frame. The head restraint arrangement includes a second locking element that is engageable with the first locking element. Upon a sufficient impact to the vehicle, the head restraint arrangement is configured to move with respect to the seatback frame from an initial position toward a support position. Furthermore, the locking elements are configured to allow movement of the head restraint arrangement toward the support position, while inhibiting movement toward the initial position.
