ABSTRACT:
This invention relates to a motorized window regulator for motor vehicles, which regulator is provided with a torque limiting mechanism of particularly advantageous construction and operation. According to the invention, a motor transmits motion to the window via a kinematic operating linkage, which comprises a cylindrical surface on which a spiral spring with preloaded turns is interference mounted. The ends of the spring engage alternately with a stop rotating coaxially to the surface such that they become urged to deform the spring in opposition to its preloading, so as to withdraw it resiliently from the cylindrical surface.
