Abstract
A cable tensioner for a vehicle window regulator includes a screw and nut assembly with an irreversible thread lead angle, a first spring designed to actuate the screw and nut assembly when there is slack in a cable and a second spring designed to block the screw and nut assembly when there is excessive tension in the cable. The cable tensioner ensures that compensation for the elongation of the cable is irreversible.
