Abstract
A disc recliner 18 for a seat assembly includes a fixed plate 22 secured to a seat cushion 12 and a rotatable plate 30 secured to a seat back 14. Each of the fixed and rotatable plates 22,30 has a plurality of teeth 40,48, the number of teeth not being equal. A flex spline 26 has a plurality of teeth 52, the number of teeth being equal to the number of teeth on the fixed plate 22. A wave generator 28 causes a portion of the teeth 52 on the flex spline 26 to meshingly engage with the teeth 40,48 on the fixed and rotatable plates 22,30. Rotation of the wave generator 28 causes the teeth 52 on the flex spline 26 which meshingly engage with the teeth 40,48 on the fixed and rotatable plates 22,30 to change, thereby causing the rotatable plate 30 to rotate relative to the fixed plate 22, which in turn causes the seat back 14 to pivot relative to the seat cushion 12.
