Patent ID: 7883144

Claim:
A vehicle seat comprising: a seat back including a frame; a guide supported within the seat back frame for limited movement relative to the seat back frame between an extended position and a retracted position; a biasing member provided within the seat back frame and connected to the guide to bias the guide to retract relative to the seat back frame toward the retracted position; a cable having a first end mounted to a top portion of the seat back frame and a second end mounted to the bottom portion of the seat back frame, the cable cooperating with the guide to overcome the bias of the biasing member to extend the guide toward the extended position; a rotary actuator mounted near the bottom portion of the seat back frame cooperating with the cable to extend and retract the cable; a release mechanism cooperating with the guide to secure the guide in the extended position; at least one rod extending from the seat back frame and having a plurality of notches provided therein for providing a series of height adjustment positions; a locking member provided within the guide to cooperate with the plurality of notches to retain the at least one rod at one of the series of height adjustment positions; and a head restraint mounted on the at least one rod such that movement of the at least one rod creates movement of the head restraint; wherein actuation of the release mechanism and the rotary actuator releases the guide so that the guide and the at least one rod are retracted by the biasing member to retract the head restraint relative to the seat back, and return actuation of the rotary actuator returns the guide and the at least one rod to the extended position by extending the cable to extend the head restraint relative to the seat back.
