Abstract
A window regulator includes a rotatable hub that is coupled to a traveller by a cable, such that rotation of the hub raises and lowers the traveller. The hub is mounted on a driven gear which is rotated by a drive gear. The hub and the driven gear are concentrically mounted around a post, which defines an outer surface that is frictionally engaged by a coil spring that is coupled both to the driven gear and to the hub. The coil spring brakes rotation of the hub when the traveller is pushed downwardly. The drive gear and its associated bushings are removably mounted on the window regulator to allow easy replacement.
