Window regulator and method of assembly of a window regulator

Abstract

A window regulator device includes a rail having at least one projecting lug, a plate having at least one lug, a drive cable, and a cable drum placed in a recess of the plate. The plate is fixed to the rail by a joint action of a tensioned drive cable and the mutual imbrication of the lugs of the plate and the rail. The assembly of the window regulator device is simplified, and the drum can be fixed independently of the mounting and removal of an actuation motor.

Claims

1. A window regulator device comprising: at least one rail including at least one rail lug that projects from the at least one rail;a plate including at least one plate lug and a recess;a drive cable; anda cable drum placed in the recess of the plate, wherein the plate is fixed to the at least one rail by joint action of a tensioned drive cable and mutual imbrication of the at least one plate lug and the at least one rail lug.

2. The window regulator device of claim 1, wherein the cable drum is held in the recess of the plate by the at least one rail lug.

3. The window regulator device of claim 1, wherein the at least one rail includes at least one cut-out that isolates the at least one rail lug.

4. The window regulator device of claim 1, wherein the at least one rail includes at least one hole to receive the at least one plate lug.

5. The window regulator device of claim 1, wherein the plate includes at least one slot to receive the at least one rail lug.

6. The window regulator device of claim 1, further including an actuation motor fixed to the plate that engages the cable drum.

7. The window regulator device of claim 6, wherein the actuation motor is fixed to the plate at a fixing point, and wherein the fixing point is located on the at least one rail.

8. A door module comprising: a panel;at least one rail fixed to the panel and including at least one rail lug that projects from the at least one rail;a plate including at least one plate lug and a recess;a drive cable; anda cable drum located in the recess of the plate, wherein the plate is fixed to the at least one rail by joint action of a tensioned drive cable and mutual imbrication of the at least one plate lug and the at least one rail lug.

9. A vehicle opening frame comprising: a window regulator device including: at least one rail having at least one rail lug that projects from the at least one rail,a plate having at least one plate lug and a recess,a drive cable, anda cable drum placed in the recess of the plate, wherein the plate is fixed to the at least one rail by joint action of a tensioned drive cable and mutual imbrication of the at least one plate lug and the at least one rail lug; anda window actuated by the window regulator device.

10. A method of assembling a window regulator device, the method comprising the steps of: providing a rail including at least one rail lug that projects from the rail;placing a cable drum in a recess of a plate, the plate including at least one plate lug;securing the plate to the rail by mutual imbrication of the at least one plate lug and the at least one rail lug;positioning a drive cable along a cable run from the cable drum; andtensioning the drive cable to immobilize the plate against the rail.

11. The method of assembly of claim 10, further including a step of fixing an actuation motor to the plate.

12. A method of removing an actuation motor for a window regulator device, the window regulator device including at least one rail having at least one rail lug that projects from the at least one rail, a plate including at least one plate lug and a recess, a drive cable, a cable drum placed in the recess of the plate, wherein the plate is fixed to the at least one rail by joint action of a tensioned drive cable and mutual imbrication of the at least one plate lug and the at least one rail lug, and an actuation motor fixed to the plate that engages the cable drum, the method comprising the steps of: releasing the actuation motor from the plate; andmaintaining tension of the tensioned drive cable with the cable drum held in the recess of the plate by the at least one rail lug.
