Abstract
A disc recliner for a seat assembly includes a fixed plate secured to a seat cushion and a rotatable plate secured to a seat back. Each of the fixed and rotatable plates has a plurality of teeth, the number of teeth not being equal. A flex spline has a plurality of teeth, the number of teeth being equal to the number of teeth on the fixed plate. A wave generator causes a portion of the teeth on the flex spline to meshingly engage with the teeth on the fixed and rotatable plates. Rotation of the wave generator causes the teeth on the flex spline which meshingly engage with the teeth on the fixed and rotatable plates to change, thereby causing the rotatable plate to rotate relative to the fixed plate, which in turn causes the seat back to pivot relative to the seat cushion.
