A vehicle seat back recliner assembly (20) includes a pair of recliners (22) each of which has a locking mechanism (32) including an operator (74) having a control lever (76) that pivots in opposite directions to provide recliner locking and unlocking. The control lever is pivoted in one direction to move a pair of toothed pawls (68) through a pair of cams (72) to provide locking, and the control lever is pivoted in the other direction to move the cams so as to permit movement of the pawls for the unlocking and to also move the pawls from the locking positions to the unlocked positions to permit recliner adjustment.
