Abstract
A cable deflection pulley pertaining to a window lifter comprising a drive unit, a guide rail for a driver which is connected to the window and to the cable, and cable deflection pulleys with a guide or bearing groove for the cable. The device has an axially directed assembly groove in the proximity of the bearing groove to facilitate and accelerate assembly and to reduce the amount of cable required. The assembly groove contains an area adjacent to the axis of the cable deflection pulley, and an area adjacent to the bearing groove, through which the cable is pulled from the assembly groove into the bearing groove.
Claims11
A cable window lifter for lifting a window pane comprising:
- a cable;
- drive unit;
- a driver connected to the cable and adapted to be connected to the window pane;
- a guide rail for the driver;
- and
- cable deflection pulleys having a first cable deflection pulley and a second cable deflection pulley, each pulley with a bearing groove for the cable, wherein the bearing grooves of the cable deflection pulleys lie in one common plane and configured to maintain the cable in the bearing groove during rotation;
- wherein the second cable deflection pulley has an assembly groove mounted eccentrically next to the bearing groove in an axial direction of the pulley;
- wherein the assembly groove has a first area close to an axis of the cable deflection pulley, and a second area further from the axis wherein the assembly groove adjoins the bearing groove forming a transition area,
- wherein when the cable is in the bearing groove of the first cable deflection pulley and placed along the first area of the assembly groove of the second cable deflection pulley, and when the second cable deflection pulley is rotated around its rotation axis, the cable is pulled from the assembly groove to the bearing groove of the second cable deflection pulley.
The cable window lifter according to at least one of the preceding claims wherein the assembly groove has a contour of a triangle with convex sides.
