Abstract
The invention relates to a force-transmission element for a window lifter (200; 300; 500) for transmitting a closing force (242; 342, 356) and an opening force (230; 330, 350) to a window (210; 310; 510), wherein the force-transmission element has a first force application point (216; 316, 316′; 416) for transmitting the closing force and a second force application point (222; 322, 322′; 422) for transmitting the opening force, and wherein the force application points are arranged in a displacement direction of the window and offset perpendicular to this displacement direction.
Claims17
Force-transmission element, of a window lifter for transmitting a closing force and an opening force to a window, comprising:
- a first projection for forming a first force-application point for transmitting the closing force, said first projection having a first stop surface for forming a first stop in an open position of the window;
- and
- a second projection for forming a second force-application point for transmitting the opening force, said second projection having a second stop surface for forming a second stop in a closed position of the window;
- the force-application points being offset in a displacement direction of the window and offset perpendicular to the displacement direction;
- said first projection extending in a first direction laterally from the displacement direction and said second projection extending a second direction laterally from the displacement direction and opposite of the first direction;
- and
- said first projection being disposed above said second projection;
- wherein the first and/or second stop surfaces have a circular-arc surface abutting a deflection roller when said force transmission element reaches a top or bottom of a displacement path.
A cable window lifter for lifting a window along a displacement direction to positions higher and lower than respective deflection roller axes, comprising:
- a lower deflection roller;
- an upper deflection roller;
- a cable being passed under said lower deflection roller and over upper deflection roller and being movable along said lower deflection roller and said upper deflection roller;
- a force transmission element extending along the displacement direction;
- an upper projection extending laterally from said force transmission element, said upper projection being connected to said cable along a length of said cable running from beneath said lower deflection roller;
- a lower projection extending laterally from said force transmission element, said lower projection being connected to said cable along a length of said cable running from over said upper deflection roller.
