RING TYPE RECLINER

摘要

The present invention is a recliner assembly for hingedly connecting a seat back and a seat cushion. The recliner assembly has a base plate mounted to the seat cushion, an arm mounted to the seat back and a locking mechanism for locking the seat back in one of a range of seat back positions and selectively releasing the seat back for adjustment of the seat back relative to the seat cushion and dumping the seat forwardly providing access rearward of the seat cushion. The base plate has a circular cavity with an inner circumference lined with teeth. Th e arm is mounted to the seat back and pivotally engages the base plate for sliding relative movement thereto for forward and rearward pivotal movement of the seat back. The arm has a circular cavity wi th an inner circumference lined with teeth and is coaxially mounted in a face to face manner with the circular cavity of the base plate. The locking mechanism has a plurality of pawl, a camming member and an actuator. The pawls are pivotally connected to the base plate and movable between an engaged position where the pawls lockably engage the teeth of both the base plate an d the arm and a disengaged position where the pawls are disengaged therefrom. The camming member is rotatably mounted between the base plate and the arm and is rotatable in a first sense engaging the plurality of pawls urging the pawls to the disengaged position and rotatable in an opposite sense engaging the plurality of pawls urging the pawls to the engaged position. The actuato r operatively engages the camming member for effecting the rotatable movement of the camming membe r to selectively lock and release the recliner assembly.
