Abstract

A windshield wiper device (10) especially for a motor vehicle is proposed. Said device is comprised essentially of a plate-shaped base (12), on which a drive unit (18), a wiper bearing (14) and a retaining element (26) are arranged. In accordance with the invention, the plate-shaped base (12) is provided with predetermined breaking points (36).

Claims

1. Windshield wiper device (10) including a plate-shaped base (12), on which at least one drive unit (18), at least one wiper bearing (14) and at least one retaining element (26) are arranged, characterized in that the plate-shaped base (12) has at least one predetermined breaking point (36) and stress-controlling elements (46), the stress controlling elements being arranged to increase on the predetermined breaking point (36) a stress in the base (12) in an impact with the windshield wiper device (10) to cause the predetermined breaking point (36) to one of bend and break off completely, and

characterized in that the at least one predetermined breaking point (36) is embodied as a hole having a perimeter and a stress-controlling element (46) is embodied as one of a recess and a material accumulation on the perimeter of and surrounding the hole.

2. Windshield wiper device (10) according to claim 1, characterized in that a predetermined breaking point (36) is arranged in the region of one of the retaining element (26) and the wiper bearing (14).

3. Windshield wiper device (10) according to claim 1, characterized in that the base (12) has a collar-like border along a perimeter.

4. Windshield wiper device (10) according to claim 3, characterized in that the drive unit (18) is accommodated within the border (33).

5. Windshield wiper device (10) according to claim 4, characterized in that a fastening element (44) is provided on the base (12), which serves as the fastening of a support tube.

6. Windshield wiper device (10) according to claim 5, characterized in that the at least one predetermined breaking point (36) is arranged approximately centrally in the plate-shaped base (12).

7. Windshield wiper device (10) according to claim 1, characterized in that a fastening element (44) is provided on the base (12), which serves as the fastening of a support tube.

8. Windshield wiper device (10) according to claim 1, characterized in that the at least one predetermined breaking point (36) is arranged approximately centrally in the plate-shaped base (12).

9. Windshield wiper device (10) according to claim 1, characterized in that a predetermined breaking point (36) is located in the plate-shaped base (12) between the at least one wiper bearing (14) and the at least one retaining element (26), and characterized in that a stress-controlling element (46) is located in the plate-shaped base (12) on a side of the at least one wiper bearing (14) away from the at least one predetermined breaking point (36).

10. Windshield wiper device (10) according to claim 1, characterized in that a predetermined breaking point (36) is located in the plate-shaped base (12) between the at least one drive unit (18) and the at least one retaining element (26), and characterized in that a stress-controlling element (46) is located in the plate-shaped base (12) between the at least one drive unit (18) and the at least one predetermined breaking point (36).

11. Windshield wiper device (10) according to claim 1, characterized in that the base (12) has a perimeter, and characterized in that the stress-controlling elements (46) are within the perimeter.
