Abstract

Claims (33)

1 . A deflection device for a traction cable of a window lift of a motor vehicle, the deflection device comprising:

a cable roller having a circumferential running channel for the traction cable and a central bearing opening formed therein, said cable roller being annular and having an inner ring wall surrounding said central bearing opening and an outer ring wall having said circumferential running channel;

a carrier for said cable roller; and

a carrier-side bearing journal for rotatable mounting of said cable roller, said carrier-side bearing journal having a latching groove formed therein;

said cable roller having a plurality of circumferentially distributed latching tongues being integrally formed on said inner ring wall of said cable roller and engaging in said latching groove of said carrier-side bearing journal, said latching tongues latch or clip said cable roller into said carrier-side bearing journal to create a snap connection; and

said cable roller having a mounting channel formed coaxial to said circumferential running channel for introducing the traction cable into said circumferential running channel, and in a circumferential direction of said cable roller, a local insertion point is provided via which said mounting channel opens into said circumferential running channel.

2 . The deflection device according to claim 1 , wherein:

said carrier-side bearing journal is a cylindrical or hollow-cylindrical molding on said carrier; and

said carrier and/or said cable roller is formed from plastic.

3 . The deflection device according to claim 2 , wherein:

said carrier is made from steel or aluminum.

4 . The deflection device according to claim 1 , wherein:

said central bearing opening of said cable roller has an inner diameter which amounts to at least two-thirds of an outer diameter of said cable roller; and/or

a ratio between the inner diameter of said cable roller and said outer diameter of said outer ring wall of said cable roller is less than 1 and greater than 0.4.

5 . The deflection device according to claim 4 , wherein the ratio is less than 0.9 and greater than 0.5.

6 . The deflection device according to claim 4 , wherein the ratio is less than 0.8 and greater than 0.7.

7 . The deflection device according to claim 1 , wherein said latching tongues on a cable roller side protrude axially beyond said inner ring wall and/or said outer ring wall and are directed radially inwardly.

8 . The deflection device according to claim 1 , wherein said latching tongues on a cable roller side are molded onto said inner ring wall of said cable roller.

9 . The deflection device according to claim 1 , wherein

a bead-shaped annular chamber is formed between said inner ring wall and said outer ring wall of said cable roller.

10 . The deflection device according to claim 1 , wherein:

said mounting channel is formed from a plurality of partial contact grooves; and/or

said mounting channel is molded onto said outer ring wall or between said outer ring wall and said inner ring wall on said cable roller.

11 . The deflection device according to claim 1 , wherein

said latching groove is a circumferential latching groove.

12 . A window lift for adjusting a window glass of a motor vehicle, the window lift comprising:

a traction cable for transmitting an adjustment force for adjusting the window glass; and

at least one said deflector device according to claim 1 disposed on said carrier.

13 . A door module for a vehicle door, the door module comprising:

said window lift according to claim 12 .

14 . The deflection device according to claim 1 , wherein:

said carrier is a guide rail; and

said carrier-side bearing journal is a bearing head provided for snap connection to said cable roller and is part of a bearing bolt which is joined or to be joined to said guide rail.
