ABSTRACT:
A window regulator that resists backdrive forces directly at the lift plate and rail, rather than by the drive assembly. A locking shoe mounted within the lift plate and selectively frictionally engages the rail while the drive assembly is at rest. Thus, any backdrive forces are transmitted from the window glass to the lift plate, and then directly to the rail, avoiding the drive assembly. A release fork that is coupled to the drive cable automatically disengages the locking shoe when the drive assembly is activated, and engages the locking shoe when the drive assembly disengages.
