Patent number: 11766957Abstract: 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.
