Abstract: A seatback adjustment assembly may include a recliner heart, an attachment plate, and a lever. The recliner heart is operable in an unlocked state permitting relative rotation between a seatback and a seat bottom and a locked state preventing relative rotation between the seatback and the seat bottom. The attachment plate is rotationally fixed to the recliner heart. The lever is rotatable between a first state in which the lever is engaged with the attachment plate and a second state in which the lever is disengaged from the attachment plate. When lever is in the first state and the recliner heart is in the unlocked state, rotation of the recliner heart causes corresponding rotation of the seatback relative to the seat bottom. However, the seatback is configured to rotate relative to the seat bottom without causing corresponding rotation of the recliner heart when the lever is in the second state.

Abstract: A recliner heart includes first, second and third locking plates and a pawl. The first locking plate defines a recess. The second locking plate includes a first inner diametrical surface having first teeth formed thereon. The third locking plate is disposed between the first and second locking plates and includes a second inner diametrical surface and an outer diametrical surface. The second inner diametrical surface has a notch formed therein. The outer diametrical surface has second teeth formed thereon. Some of the second teeth are meshingly engaged with some of the first teeth. The pawl is slidably disposed in the recess between a secure position in which the pawl is engaged with the notch of the third locking plate and a release position in which the pawl is disengaged from the notch of the third locking plate.
