Abstract
In a window lifter of the cable type, comprising a motor for driving the cable bearing a slide (6) linked to a second slide (7) supporting the window, the two slides (6, 7) may be coupled via an elastic tension element (16) and one (6) of the slides is fitted with an electrical switch (17), associated with the second slide (7) so as to change state when the load on the slide (7) carrying the window (8) exceeds a predetermined value and when the elastic element (16) undergoes an extension corresponding to the separation between the slides; the switch (17) forms part of an electrical supply circuit for the motor, capable of reversing its direction of rotation when this switch (17) changes state, so as to free the movable member from an obstacle in its path. This electromechanical safety device has a simple structure and a low manufacturing cost.
