ABSTRACT:
A window regulator includes an electric motor having a drive shaft, a window slider, a transmission having an input driven by a drive shaft and an output driving the slider. A geared motor includes a drive shaft, a reduction gear coupled to the drive shaft and having a transmission ratio less than1, and a piezoelectric element selectively locking the drive shaft. The window regulator can be used to prevent fraudulent opening of a window and to reduce the jamming force of an object between the window and the window frame.
