The limit control includes a cable operated stop that interact with a stepped trackway on the seat.

The lumbar support includes a lumbar cam that is rotatably mounted to a lumbar pad. The lumbar cam includes a plurality of lobes that vary in radius so that rotation of the cam causes variation in the contour of the lumbar region.
