ABSTRACT:
There is disclosed herein an automotive window regulator and drive mechanism which includes a rotatable flexible drive shaft to transmit rotational forces from the regulator arm to a worm gear supported on a lower edge of the window. The worm gear engages a rack secured to a portion of the vehicle so as to vary the position of the window. In one embodiment, both electric motor drive and manual crank drive means are provided either of which may be selectively engaged to drive the rotatable flexible shaft. The regulator end of the flexible drive shaft may be supported in meshing engagement with a portion of the regulator drive gear by means of a pinion pivot arm which arm includes indexing gears to enable the flexible cable to track the worm gear thereby reducing the flexing of the flexible drive shaft.
