Abstract

A windscreen wiper device (10), in particular for a motor vehicle, comprises at least one wiper bearing (14) provided with a bearing housing (24). The wiper shaft (22) mounted in the bearing housing (24) can move a wiper arm to a first end (26). The inventive device also comprises an element (40) which axially supports the wiper shaft (22). According to said invention, the element (40) is embodied in the form of a bridging element.

Claims

1. Windshield wiper device (10), with at least one wiper bearing (14) which is comprised of a bearing housing (24), a wiper shaft (22) that is mounted in the bearing housing (24) and can bear a wiper arm on a first end (26), and an element (40) that axially supports the wiper shaft (22), characterized in that the element (40) is embodied as a bridging element.

2. Windshield wiper device (10) according to claim 1, characterized in that the wiper shaft (22) has a shoulder (34) and the bridging element (40) is arranged between the bearing housing (24) and the shoulder (34).

3. Windshield wiper device (10) according to claim 2, characterized in that the shoulder (34) is essentially disk-shaped and essentially surrounds the wiper shaft.

4. Windshield wiper device (10) according to claim 2, characterized in that the shoulder (34) is embodied as a single piece with the wiper shaft (22).

5. Windshield wiper device (10) according to claim 1, characterized in that the bridging element (40) has at least three planes (42, 44, 46) that are coaxial to the wiper shaft, which are connected by connecting pieces (48).

6. Windshield wiper device (10) according to claim 5, characterized in that the connecting pieces (48) run diagonal to the wiper shaft (22).

7. Windshield wiper device (10) according to claim 5, characterized in that the connecting pieces (48) are arranged parallel to the wiper shaft (22).

8. Windshield wiper device (10) according to claim 7, characterized in that the connecting pieces (48) do not overlap with a projection on a plane that is parallel to the wiper shaft.

9. Windshield wiper device (10) according to claim 1, characterized in that the bridging element (40) has at least one predetermined breaking point (52).

10. Windshield wiper device (10) according to claim 9, characterized in that at least one predetermined breaking point (52) is provided in at least one plane (42, 44, 46).

11. Windshield wiper device (10) according to claim 5, characterized in that each plane (42, 44, 46) is connected to the respective adjacent plane (42, 44, 46) by at least three connecting pieces (48), and at least one predetermined breaking point (52) is provided for each connecting piece (48) in the adjacent, not the outer-edge plane (42, 46).

12. Windshield wiper device (10) according to claim 2, characterized in that the wiper shaft (22) can be driven by a drive crank (32), which is embodied as a single piece with the shoulder (34) or that serves as a shoulder itself (34).

13. Windshield wiper device (10) according to claim 1, characterized in that the bridging element (40) is protected from corrosion.

14. Windshield wiper device (10) according to claim 1, characterized in that the bearing housing (24), the wiper shaft (22) or the shoulder (34) have securing agents (37) to prevent twisting and/or displacement of the bridging element (40).

15. Windshield wiper device (10) according to claim 1, characterized in that the bridging element (40) is embodied as a single piece with the bearing housing (24).

16. Windshield wiper device (10) according to claim 13 wherein the bridging element (40) is made of plastic.
