Abstract
A cable window-lift in particular for motor vehicles and comprising a drive (1) for the alternating winding and unwinding of the cable (2) running in at least one loop and which cable, in relation to pane movement, is divided into a cable lifting portion (15) and a cable descending portion (16) and further is linked to a pane lifter (3) displaceable up and down along a guide (5), one spring element (9, 10) being provided in the cable lifting portion (15) and cable descending portion (16) resp. to compensate cable slack. To allow raising and lowering the pane in substantially play-free manner and to avert clattering and/or wind noise, the spring (9) in the cable lifting portion (15), which is compressed when in the pane closed position, evinces a spring force greater than the resultant of the pane weight and the frictional forces arising during pane motion and also larger than the spring force of the spring (10) in the cable descending portion (16).
