Abstract

A windshield wiper assembly for a vehicle having a drive device provided with an electric motor having a pole-well, and a transmission that can be driven by the electric motor, which is operatively connected to at least one wiper arm, and having a device for fastening the drive device to the vehicle. The device is provided with a tab surrounding the pole-well of the electric motor on the peripheral side, at least in some areas, which is provided with a free end, which protrudes from the pole-well and which is fastened to the vehicle.

First claim

What is claimed is:

1. A windshield wiper assembly for a vehicle, comprising:
at least one wiper arm;
a drive device that includes an electric motor having a pole-well and a transmission, which is drivable by the electric motor and is operatively connected/operatively connectable to the at least one wiper arm; and
a fastener adapted to fasten the drive device on the vehicle, the fastener having a bracket that encompasses the pole-well of the electric motor at least in some areas, the bracket having a first end and a second end, the first end attaching to the pole-well and the second end being a free end that protrudes from the pole-well and is fastened to the vehicle at a connecting point,
wherein the bracket has a bottom surface that faces the connecting point and the pole-well and an upper surface that faces away from the connecting point and the pole-well,
wherein the bracket includes at least one reinforcement rib that protrudes from the upper surface of the bracket in a direction away from the connecting point and the pole-well, the at least one reinforcement rib extending along peripheral edges of the upper surface of at least the free end of the bracket, and
wherein the free end of the bracket is a planar portion that extends along a plane and wherein a rotating axis of the pole-well lies in the plane of the free end of the bracket, such that in a height direction that extends from a bottom of the pole-well to a top of the pole-well to which the first end of the bracket is attached, the free end of the bracket is positioned at a same height as the rotating axis of the pole-well.

2. The windshield wiper assembly according to claim 1 , wherein the bracket extends along the periphery of the pole-well over at least 25°.

3. The windshield wiper assembly according to claim 1 , wherein the bracket has a vibration-dampening effect at least in sections.

4. The windshield wiper assembly according to claim 1 , wherein the bracket is integrally fastened to the pole-well.

5. The windshield wiper assembly according to claim 1 , wherein the bracket is fastened to the pole-well in a form-fitting manner.

6. The windshield wiper assembly according to claim 1 , wherein the pole-well has a housing, and wherein a housing jacket wall section of the housing being formed by the bracket.

7. The windshield wiper assembly according to claim 1 , wherein a decoupling element for decoupling vibrations is assigned to the free end of the bracket.

8. The windshield wiper assembly according to claim 1 , wherein the bracket extends along the periphery of the pole-well by 170° to 190°.

9. The windshield wiper assembly according to claim 1 , wherein the bracket extends along the periphery of the pole-well by 180°.

10. The windshield wiper assembly according to claim 1 , wherein the bracket is s-shaped.

11. The windshield wiper assembly according to claim 1 , wherein the upper surface of the bracket extends continuously from the first end to the second end.

12. The windshield wiper assembly according to claim 1 , wherein the at least one reinforcement rib extends perpendicularly from the planar portion of the free end of the bracket.
