An assembly for adjusting the angular position of a seat back member ( ) relative to a seat cushion member ( ) having an anchor shaft ( ) supported by a bracket ( ) that is attached to the seat cushion member ( ) and supports a pawl plate ( ) transmitting forces thereto from a rod ( ) when in a latched position. The anchor shaft ( ) extends through the slot ( ) to prevent longitudinal movement of the pawl plate ( ) while allowing the pawl plate ( ) to rotate about an axis parallel to the longitudinal axis (A) of the rod ( ). A pair of guide plates ( ) guide the pawl plate ( ) to move in an arc transversely into and out of engagement with the rod ( ) between the latched and unlatched positions. An actuator pin ( ) extends laterally from the pawl plate ( ) and a lever ( ) is supported on an axle ( ), which is supported for rotation by the housing ( ). The lever ( ) includes a slot ( ) surrounding the pin ( ) for moving the pin ( ) in an arc to rotate the pawl plate ( ) between the latched and unlatched positions. The housing ( ) is supported on the anchor ( ) for guiding movement of the pawl plate ( ) between the latched and unlatched positions.

Linear recliner assembly

A recliner assembly for an automotive seat has a seat cushion and a seat back pivotally mounted to the seat cushion. The recliner assembly includes a housing and a cover plate encapsulating the housing. The cover plate has an outer ring with a plurality of teeth. Three pawls are mounted within the housing. The pawls each have a toothed surface and are moveable between a locked position and an unlocked position. With the pawls in the locked position, the toothed surfaces engage the teeth of the cover plate to secure the seat back relative to the seat cushion. With the pawls in the unlocked position, the toothed surfaces are spaced from the teeth of the cover plate to allow movement of the seat back relative to the seat cushion. Three pivot protrusions extend from the housing for providing a pivot point for each of the pawls. Three guide protrusions similarly extend from the housing for guiding each of the pawls between the engaged and disengaged positions. A cam is movably mounted relative to the housing and has three lobes for engagement with the pawls and moving the pawls between the engaged and disengaged positions. A single substantially spiral spring has a first end engaging one of the lobes of the cam and a second end engaging a guide protrusion for continuously biasing the lobes of the cam toward engagement with the pawls which continuously biases the toothed surfaces of the pawls toward engagement with the teeth of the cover plate.

Recliner assembly

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.

A linear recliner assembly for use with a vehicle seat assembly. The vehicle seat assembly has a seat cushion and a seat back pivotally mounted to the seat cushion for forward and rearward reclining movement. The linear recliner assembly has a housing mounted to the seat cushion. An actuating rod is pivotally connected to the seat back at a first end thereof and slidably mounted with the housing at an opposite end thereof. The actuating rod is biased to urge the seat back to the forward reclining movement. A pivotally mounted pawl is biased into pivotal engagement with the actuating rod. A rotatable camming member engages the pawl in a camming relationship so as to move the pawl between a releasably engaged position engaging the actuating rod preventing reclining movement and a released position disengaging the actuating rod mechanism allowing reclining movement. The pawl engages the actuating rod such that when a force applied to the seat back the force is transmitted to the seat cushion through the camming member.
