Abstract

A cable-drum window regulator with a spring cable tensioner is provided with a spring retainer assembly securing the spring to the cable. The spring retainer is advantageously assembled prior to final installation of the cable into the regulator mechanism. The retainer assembly comprises a retainer with a hollow interior sized to receive the cable and the spring, having an opening at one end sized to allow passage of the cable but not the spring, and an endpiece with one or more projections which preferably snap fit together with the retainer, securing or capturing the spring between the retainer and the endpiece. The retainer may have snap fit projections which captivate the endpiece, or alternatively, the endpiece may have snap fit projections which captivate the retainer. The endpiece may be attached to the cable directly or indirectly onto a conduit. The cable has cable end balls which are used to attach the cable to the drive means. In one embodiment the end balls are attached to the cable before the retainer assembly is attached, so a slot is provided to allow the insertion of the cable into the retainer assembly. The retainer and the mounting bracket may be of unitary construction.
