Abstract
A seat recliner having seat back and cushion arms connected to each other about a pivotal axis for adjustable movement. Plate-like ends of the arms are located adjacent each other with a locking ring therebetween pivotally fixed to the seat back arm end encircling the pivotal axis. Locking teeth of the ring extend inwardly and are arranged in an arcuate shape about the pivotal axis. A locking dog is received within the locking ring between the ends of the arms and has a plate-like construction slidably supported between the arm ends. Spaced guides on the seat cushion arm end guide the dog during movement between locking and nonlocking positions. A toothed end of the dog engages the locking ring teeth in the locking position to prevent relative pivoting between the arms and disengages the ring teeth in the nonlocking position to permit such pivoting for adjustment of the arms. A cam is received within an opening of the dog and is movable about the pivotal axis to move the dog between the locking and nonlocking positions. A manual actuator pivots the cam in one direction to slidably engage a cam surface with a locking surface of the dog opening to move the dog to the locking position…
