ABSTRACT:
A vehicle seat is disclosed that provides longitudinal adjustment and height adjustment of a head restraint by actuation of a manual release. One embodiment discloses a vehicle seat with a rod extending from a seat back and a frame mounted to the rod. A head restraint is mounted to the frame by a linkage to extend and retract. A locking mechanism cooperates with the head restraint and the frame for permitting incremental locking positions of the head restraint relative to the frame. A manual release releases the locking mechanism to extend and retract the head restraint relative to the rod. Another embodiment includes an eccentric mechanism pivotally connected to the frame. A wire spring is mounted to the frame for engaging a notch in the rod. An actuator rotates an eccentric mechanism for disengaging the wire spring from the notch in the rod for permitting height adjustment.
