Window regulator and method of assembly of a window regulator
View Patent ↗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.
1. A window regulator device comprising:
at least one rail including at least one rail lug that projects from the at least one rail, the at least one rail defining a first direction;
a plate including at least one plate lug and a recess;
a tensioned drive cable; and
a cable drum placed in the recess of the plate, wherein the plate is firmly held flat and fixed to the at least one rail by joint action of the tensioned drive cable and mutual imbrication of the at least one plate lug and the at least one rail lug, the mutual imbrication immobilizing the plate in the first direction and in a second direction perpendicular to the first direction, and the tension of the tensioned drive cable blocking the plate in a third direction that is perpendicular to the first direction and the second direction;
wherein the imbrication comprises the rail lug projecting in the third direction through a slot in the plate.
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 tensioned drive cable; and
a cable drum located in the recess of the plate, wherein the plate is firmly held flat and fixed to the at least one rail by joint action of the tensioned drive cable and mutual imbrication of the at least one plate lug and the at least one rail lug, the mutual imbrication immobilizing the plate in a first direction and in a second direction perpendicular to the first direction, and the tension of the tensioned drive cable blocking the plate in a third direction that is perpendicular to the first direction and the second direction;
wherein the imbrication comprises the rail lug projecting in the third direction through a slot in the plate.
9. A vehicle opening frame, a vehicle defining a direction of travel, a vertical direction perpendicular to the direction of the travel and a lateral direction perpendicular to the direction of travel and to the vertical direction, the 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, the at least one rail extending in the vertical direction of the vehicle,
a plate having at least one plate lug and a recess,
a tensioned drive cable, and
a cable drum placed in the recess of the plate, wherein the plate is firmly held flat and fixed to the at least one rail by joint action of the tensioned drive cable and mutual imbrication of the at least one plate lug and the at least one rail lug; and
a window actuated by the window regulator device, the mutual imbrication immobilizing the plate in the vertical direction and in the lateral direction, and the tension of the tensioned drive cable blocking the plate in the direction of travel;
wherein the imbrication comprises the rail lug projecting in the third direction through a slot in the plate.
10. The door module of claim 8 , wherein the cable drum is held in the recess of the plate by the at least one rail lug.
11. The door module of claim 8 , wherein the at least one rail includes at least one cut-out that isolates the at least one rail lug, the at least one cut-out of the rail is shaped like a trapezium, and the lug projects from a short parallel side of the trapezium.
12. The vehicle opening frame of claim 9 , wherein the cable drum is held in the recess of the plate by the at least one rail lug.
13. The vehicle opening frame of claim 9 , wherein the at least one rail includes at least one cut-out that isolates the at least one rail lug, the at least one cut-out of the rail is shaped like a trapezium, the lug projects from a short parallel side of the trapezium.
14. The window regulator device of claim 3 , wherein the at least one cut-out of the rail is shaped like a trapezium, and the lug projects from a short parallel side of the trapezium.
15. 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 tensioned 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 the at least one rail lug holding the cable drum in the recess of the plate.
16. The window regulator device of claim 15 , wherein the at least one rail includes at least one cut-out that isolates the at least one rail lug, the at least one cut-out of the at least one rail is shaped like a trapezium, and the lug projects from a short parallel side of the trapezium.
