摘要： An apparatus includes a seat back having an outer surface that selectively contacts a seat occupant and a head restraint extending from the seat back that has a head restraint portion that selectively contacts the seat occupant. The head restraint portion is moveable between a forward position and a rearward position. The apparatus also includes a head restraint control assembly having an actuator, a lock mechanism, and a lock mechanism resetting device. The actuator transfers an actuation force to the head restraint portion for initiating movement of the head restraint portion from the rearward position to the forward position. The lock mechanism selectively restrains the headrest portion from moving from the forward position to the rearward position. The lock mechanism will restrain the headrest portion from moving from the forward position to the rearward position in a first actuation event and selectively reset by action of the lock mechanism resetting device in order to restrain the headrest portion from moving from the forward position to the rearward position in a second actuation event. The lock mechanism resetting device will reset the lock mechanism without manipulation from an outside source.
