ABSTRACT:
A window regulator employs a drive cable to regulate opening and closing of a window in a vehicle. The drive cable is attached to a glider which is attached to the window, and extends around a loop which includes first and second guide elements and a drive drum. Rotation of the drive drum causes movement of the cable which in turn causes movement of the window. One of the guide elements is coupled to a torsion spring which causes the guide element to be forced outward to increase the circumference of the loop traveled by the cable and thereby to maintain tension on the cable. The guide element may take the form of a rotatable pulley.
