Abstract

The invention relates to a windshield wiper device (10), in particular for a motor vehicle, comprising a support (12), on which a bearing (18) is arranged, which supports a wiper shaft (22). In this case, a retaining element (20) is provided, which detachably connects the bearing (18) to the support.

Claims

1. Windshield wiper device (10), for a motor vehicle, comprising a support (12), on which at least one bearing (18) is arranged, which supports at least one wiper shaft (22), the bearing (18) and the wiper shaft (22) extending along an axis about which the wiper shaft is adapted to rotate within the bearing, characterized in that at least one retaining clip (20) detachably connects the bearing (18) to the support such that the bearing separates from the support in the event of an increased force on the wiper shaft due to impact with a pedestrian, the clip gripping around a portion of the support and a portion of the bearing to detachably connect the bearing to the support, the clip extending at least partially about the axis.

2. Windshield wiper device (10) according to claim 1, characterized in that the support (12) has a receptacle (34) to accommodate the bearing (18).

3. Windshield wiper device (10) according to claim 2, characterized in that the bearing (18) includes at least one tube.

4. Windshield wiper device (10) according to claim 3, characterized in that the clip (20) grips around the bearing (18) at least partially in a radial fashion.

5. Windshield wiper device (10) according to claim 2, characterized in that the receptacle (34) is C-shaped in cross section and has an interior, and in that the bearing (18) is inserted into the interior of the C-shaped receptacle.

6. Windshield wiper device (10) according to claim 5, characterized in that the clip grips partially around the receptacle such that the clip is detachable in the event of an impact with a pedestrian.

7. Windshield wiper device (10) according to claim 5, characterized in that the bearing is fixed in the receptacle by the at least one retaining clip and by a second retaining clip, the clips gripping partially around the receptacle such that the clips are detachable in the event of an impact with a pedestrian.

8. Windshield wiper device (10) according to claim 1, characterized in that the bearing (18) includes at least one tube.

9. Windshield wiper device (10) according to claim 1, characterized in that the clip (20) grips around the bearing (18) at least partially in a radial fashion.

10. Windshield wiper device (10) according to claim 1, characterized in that the support (12) includes a bearing holder (16) having a side wall defining a receptacle (34) receiving the bearing and a radial opening, and in that the at least one retaining clip (20) extends across the radial opening to detachably retain the bearing in the receptacle.

11. Windshield wiper device (10) according to claim 1, characterized in that the bearing is connected to the support by the at least one retaining clip and by a second retaining clip.

12. Windshield wiper device (10), for a motor vehicle, comprising a support (12), on which at least one bearing (18) is arranged, which supports at least one wiper shaft (22), characterized in that at least one retaining clip (20) detachably connects the bearing (18) to the support such that the bearing separates from the support in the event of an increased force on the wiper shaft due to impact with a pedestrian, characterized in that the support (12) has a receptacle (34) to accommodate the bearing (18), wherein the receptacle (34) is C-shaped in cross section and has an interior, wherein the bearing (18) is inserted into the interior of the C-shaped receptacle, and wherein the bearing is fixed in the receptacle by the at least one retaining clip and by a second retaining clip, the clips gripping partially around the receptacle such that the clips are detachable in the event of an impact with a pedestrian.

13. Windshield wiper device (10), for a motor vehicle, comprising a support (12), on which at least one bearing (18) is arranged, which supports at least one wiper shaft (22), characterized in that at least one retaining clip (20) detachably connects the bearing (18) to the support such that the bearing separates from the support in the event of an increased force on the wiper shaft due to impact with a pedestrian, in that the bearing (18) and the wiper shaft (22) extend along an axis, in that the support (12) includes a bearing holder (16) having a side wall defining a receptacle (34) receiving the bearing and a radial opening, and in that the clip extends across the radial opening to detachably retain the bearing in the receptacle.

14. Windshield wiper device (10) according to claim 13, characterized in that the at least one retaining clip (20) includes two retaining clips (20), each clip extending across the radial opening.

15. Windshield wiper device (10) according to claim 13, characterized in that the bearing (18) includes at least one tube.
