Abstract
A disc recliner for a seat assembly includes a guide plate and a tooth plate rotatably coupled to the guide plate. A rotatable shaft moves a pawl between a first position engaging the tooth plate to prevent pivotal movement of the seat back and a second position disengaged with the tooth plate to allow pivotal movement of the seat back. A leaf spring extends between a first end secured to the guide plate and a second end having a convex curve portion engaging a lobe on the shaft. The spring biases the shaft in a first direction to maintain the pawl in the first position. Rotation of the shaft in a second direction moves the pawl from the first position to the second position as the lobe pushes against and rides along the convex curve portion of the spring, thereby controlling an actuation effort of the disc recliner.
