Drive device for cable actuated window lifter, has cable length compensation formed as elastic spring cable clamping device to engage traction cable, around clamping cable loop, before and after cable drum

摘要

The device has an automatic cable length compensation, which has multiple deflection rollers (40,41), over which a locked loop shaped traction cable (2), is guided. The cable length compensation is designed as elastic spring cable clamping device (20), which engages the traction cable, around the clamping cable loop, before and after the cable drum (10) to tighten in the direction of movement of the traction cable.
