ABSTRACT:
Recliner mechanism for a vehicle seat has a combination cam and bearing member operated by a manual control member positioned at the end of a rotatable support shaft for lifting one toothed locking segment carried by the seatback frame out of contact with another carried by the seat base, thus permitting the seatback to be tilted to any desired angle. Release of the control member in any position of adjustment permits the cooperating toothed locking segments to move together into locking engagement. A seatback return spring biases the seatback forwardly, while a torsion spring biases the control member and cam member toward their locked position. Where desired, a recliner mechanism can be provided for each side of the seatback with the two mechanisms being mounted at the opposite ends of the rotatable support shaft and operated by a single control member.
