Abstract

Windshield wiper device (400) for a motor vehicle with at least one wiper bearing (42) and a fastening element (44) that is connected to a vehicle body, wherein a decoupling element (43) for decoupling noise is arranged between the at least one wiper bearing (42) and the fastening element (44), wherein the decoupling element (43) and/or the wiper bearing (42) is detachably connected to the fastening element (44).

Claims

1. Windshield wiper device (100, 400, 500, 700) for a motor vehicle with at least one wiper bearing (12, 42, 50, 70) and a fastening element (14, 44, 51, 71) that is connected to a vehicle body, wherein a decoupling element (15, 43, 52, 72) for decoupling noise is arranged between the at least one wiper bearing (12, 42, 50, 70) and the fastening element (14, 44, 51, 71), characterized in that the decoupling element (15, 43, 52, 72) and/or the wiper bearing (12, 42, 50, 70) is detachably connected to the fastening element (14, 44, 51, 71).

2. Windshield wiper device (100, 400, 500, 700) according to claim 1, characterized in that fastening element (14, 44, 51, 71) and/or the decoupling element (15, 43, 52, 72) are provided with an undercut, and the fastening element (14, 44, 51, 71) and/or the decoupling element (15, 43, 52, 72) are manufactured of a deformable material.

3. Windshield wiper device (100, 400, 500, 700) according to claim 2, characterized in that the undercut is a material projection in the end area of the fastening element (14, 44, 51, 71).

4. Windshield wiper device (400, 500) according to claim 3, characterized in that the material projection in the end area of the fastening element (44, 51) is embodied as a thickening (45, 54).

5. Windshield wiper device (700) according to claim 3, characterized in that the material projection in the end area of the fastening element (71) features several teeth (74) arranged one after the other.

6. Windshield wiper device (400, 500, 700) according to claim 2, characterized in that the undercut is a hook-shaped end area (47, 55, 75) of the decoupling element (43, 52, 72).

7. Windshield wiper device (500, 700) according to claim 2, characterized in that a disk (53, 73) is arranged between the material projection in the end area of the fastening element (51, 71) and the hook-shaped end area (55, 75) of the decoupling element (52, 72).

8. Windshield wiper device (400, 500, 700) according to claim 2, characterized in that the undercut on the fastening element (44, 51, 71) features a diagonal bearing surface on which the disk (53, 73) or the decoupling element (43) rests.
