Abstract
A seat back 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 pivotally connected to each other with a locking ring therebetween fixed to the seat back arm encircling the pivotal axis. Locking teeth of the ring extend inwardly and are arranged in an arcuate shape about the pivotal axis to be engaged by a toothed end of a locking dog that is slidable between the plate ends and between spaced guides on the seat cushion arm end. A spring biased actuator and cam normally position the dog in a locking position where its toothed end engages the ring teeth to prevent pivoting of the seat back arm. A blocking pin on the dog and a blocking surface on the seat back arm cooperate to prevent engagement of the dog and the ring during pivoting of the seat back arm to the easy-enter position. The blocking surface of the seat back arm end is preferably provided by an arcuate slot through which the blocking pin on the dog extends, and the blocking pin on the dog is preferably located adjacent the toothed dog end.
