Abstract

The window lifter (1) may, for example, be of the twisted cable type (3) driven by a motorized reduction gear (2) wound around return pulleys (4, 5) and sliding in a guide rail (6); a carriage (8) carrying the window pane (9) is fixed to the strand of the cable passing into the rail (6); damping elements (11) such as flat metal springs, for example, are fixed to the ends of the guide rail (6) and to the door panel (7), which makes it possible to damp out a hard impact against an obstacle encountered by the window pane (9).
