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. The 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 with 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 and 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 actuator operatively engages the camming member for effecting the rotatable movement of the camming member to selectively lock and release the recliner assembly.

Ring-type recliner

A vehicle seat assembly comprising a seat back assembly pivotally coupled to a seat cushion assembly by a recliner assembly and pivotal between a plurality of reclined positions. The recliner assembly including a fixed plate secured to the seat cushion assembly and a seat back arm member secured to and movable with the seat back assembly. A locking mechanism including a pawl member and a locking control arm are coupled between the fixed plate and the seat back arm member and moveable between a locked position retaining the seat back cushion in a desired reclined position and an unlocked position allowing movement of the seat back cushion to any of the desired reclined positions. A seat back release member interconnects with each of the pawl member and the locking control arm to simultaneously move the locking mechanisms between the locked and unlocked position via a common pivot pin.
