Cable tensioning device for a window regulator

摘要

The adjuster has an assembly of screw (12) and nut (11) having a reversible screw lead angle. A spring (15) is adapted to absorb a reversible low tension of a cable (10). Another spring (16) is adapted to actuate the screw in the nut when the former spring is in maximal expansion, where stiffness of the former spring is greater than that of the latter spring. An independent claim is also included for a frameless door comprising a window regulator.
