ABSTRACT:
A window regulator for raising a lowering a window pane in a motor vehicle. The regulator includes a scissors linkage including crossed lever arms connected at a pivot axis. The lever arms are attached at their upper ends to spaced points on the lower edge of the window pane and a cable is connected to the linkage at the pivot axis of the crossed arms. The cable is wrapped around a drum driven by a motor and is further trained over an upper pulley positioned above the pivot axis of the linkage and a lower pulley positioned below the pivot axis of the linkage. The regulator further includes a lower cross rail defining a rear pivot pivotally mounting the lower end of one of the lever arms, an intermediate pivot pivotally mounting the lower pulley, and a forward slot slidably mounting the lower end of the other lever arm.
The arrangement is such that movement of the cable through a first distance results in movement of the windowpane through a second distance greater than the first distance, thereby providing a speed multiplier effect.
