ADJUSTABLE HEAD RESTRAINT FOR VEHICLE SEAT
First Claim
1. A vehicle seat comprising:
- a seat back for supporting a back of an occupant;
a rod mounted to and extending from the seat back;
a frame mounted to the rod;
a linkage mounted to the rod to extend and retract relative to the frame in a forward and rearward direction;
a head restraint mounted to the linkage for supporting a head of an occupant and for extending and retracting relative to the frame;
a locking mechanism cooperating with the head restraint and the frame for permitting incremental locking positions of the head restraint relative to the frame; and
a manual release for releasing the locking mechanism to extend and retract the head restraint relative to the rod.

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.

15. A vehicle seat comprising:
-
a seat back for supporting a back of an occupant; a rod mounted to and extending from the seat back, the rod having a series of notches formed therein; a frame mounted to the rod to slide along the rod; a head restraint mounted to the frame for supporting a head of an occupant; an eccentric mechanism pivotally connected to the frame; a wire spring mounted to the frame for engaging one of the notches of the rod, the wire spring cooperating with the eccentric mechanism such that rotation of the eccentric mechanism to a released position retracts the wire spring from the notch; and an actuator for rotating the eccentric mechanism from a locked position to the released position to slide the head restraint and frame along the rod. - View Dependent Claims (16, 17, 18)

19. A vehicle seat comprising:
-
a seat back for supporting a back of an occupant; a rod mounted to and extending from the seat back, the rod having a series of notches formed therein; a frame mounted to the rod to slide along the rod; a head restraint mounted to the rod for supporting a head of an occupant and for extending and retracting relative to the frame in a forward and rearward direction; a first locking mechanism cooperating with the head restraint and the frame for permitting incremental locking positions of the head restraint relative to the frame; a second locking mechanism cooperating with the notches for maintaining a height position of the head restraint relative to the rod; and a manual release for releasing the first locking mechanism to extend and retract the head restraint relative to the rod and for releasing the second locking mechanism for permitting height adjustment of the head restraint. - View Dependent Claims (20)
