Title: Pivot ring for a manual clutch

Abstract: A pivot ring for a clutch assembly which has a first annular segment, a second annular segment, and a radial segment. The first annular segment has a first face on a front side of the pivot ring and the second annular segment has a second face, predominately opposing the first face, on a back side of the ring. The radial segment is disposed between the first annular segment and the second annular segment, connecting the first annular segment and the second annular segment. The first annular segment, the second annular segment, or both the first annular segment and the second annular segment can include axial protrusions with arcuately shaped pivot portions. Preferably, in the clutch assembly, the pivot ring is disposed between the diaphragm spring and the pressure plate, allowing for rotational freedom between the pressure plate and the diaphragm spring.
