Abstract

The invention relates to a windscreen wiper device (10), in particular for a motor vehicle, screwed to a chassis (12). Conventional windscreen wiper devices do not yield on an impact with a pedestrian and hence represent a significant injury risk for pedestrians. According to the invention, the risk of injury may be reduced whereby the housing openings (30), provided for housing screws (11) in the chassis (12) comprise a slot (31) at the edge of the housing opening (30).

Claims

1. A windscreen wiper device (10), which is screwed to a chassis (12), characterized in that receiving openings (30) in the chassis, which are provided to receive screws (11) connected to the wiper device (10), have a slot (31) at an edge of the receiving openings (30), each slot having a V-shaped configuration with diverging, generally linear sides, characterized in that the chassis has a wall having an open edge and defining the openings (30) and the slots (31), and characterized in that each slot (31) extends from the open edge of the wall to the associated opening (30).

2. The windscreen wiper device (10) as claimed in claim 1, characterized in that the slots (31) extend parallel to a wiper shaft (15).

3. The windscreen wiper device (10) as claimed in claim 1, characterized in that the slots (31) have a bottleneck (32) in a region of transition to the receiving openings (30).

4. The windscreen wiper device (10) as claimed in claim 3, characterized in that a width of the bottleneck is at most as great as diameters of the screws (11).

5. The windscreen wiper device (10) as claimed in claim 1, characterized in that the screws (11) are inserted through a rubber element (13).

6. The windscreen wiper device (10) as claimed in claim 1, characterized in that a force of detachment, with which the screws (11) can be pressed out of the receiving openings (30), is individually adjustable to a specific value.

7. The windscreen wiper device (10) as claimed in claim 1, characterized in that receiving openings for receiving the screws (11) are also provided in the windscreen wiper device.

8. A windscreen wiper device (10), which is screwed to a chassis (12), wherein receiving openings (30) in an open edge of a wall of the chassis (12), which receives screws (11) connected to the wiper device (10), has slots (31) at an edge of the receiving openings (30), and wherein each screw (11) is inserted through a rubber element (13) and threadedly engages a nut (14), the rubber elements (13) being between the nuts (14) and the chassis (12), characterized in that each nut (14) is fastened to each rubber element (13) independently of each screw.

9. The windscreen wiper device (10) as claimed in claim 8, characterized in that the slot has a V-shaped configuration with diverging, generally linear sides.

10. The windscreen wiper device (10) as claimed in claim 8, characterized in that the slot (31) has a bottleneck (32) in a region of transition to the receiving opening (30).

11. The windscreen wiper device (10) as claimed in claim 8, characterized in that the nut (14) is fastened to the rubber element (13) by one of vulcanizing, bonding and encapsulating.

12. A motor vehicle comprising a chassis (12) and a windscreen wiper device (10) secured to the chassis (12) with screws (11) connected to the wiper device (10), the chassis (12) having therein receiving openings (30) which receive the screws (11), and the chassis (12) having therein a slot (31) at an edge of each receiving opening (30), each slot having a V-shaped configuration with diverging, generally linear sides, characterized in that the chassis has a wall having an open edge and defining the openings (30) and the slots (31), and characterized in that each slot (31) extends from the open edge of the wall to the associated opening (30).

13. A motor vehicle as claimed in claim 12, characterized in that the slots (31) extend parallel to a wiper shaft (15).

14. A motor vehicle as claimed in claim 12, characterized in that the slots (31) have a bottleneck (32) in a region of transition to the receiving openings (30).

15. A motor vehicle as claimed in claim 14, characterized in that a width of the bottleneck is at most as great as diameters of the screws (11).

16. A motor vehicle as claimed in claim 12, characterized in that the screws (11) are inserted through a rubber element (13).

17. A motor vehicle as claimed in claim 12, characterized in that a force of detachment, with which the screws (11) can be pressed out of the receiving openings (30), is individually adjustable to a specific value.

18. A motor vehicle as claimed in claim 12, characterized in that receiving openings for receiving the screws (11) are also provided in the windscreen wiper device (10).

19. A motor vehicle comprising a chassis (12) and a windscreen wiper device (10) secured to the chassis (12) with screws (11) connected to the wiper device (10), the chassis (12) having therein receiving openings (30) in an open edge of a wall which receive the screws (11), and the chassis (12) having therein a slot (31) at an edge of each receiving opening (30), and wherein each screw is inserted through a rubber element (13) and threadedly engages a nut (14), the rubber element (13) being between the nut (14) and the chassis (12), characterized in that the nut (14) is fastened to the rubber element (13) independently of the screw.

20. A motor vehicle as claimed in claim 19, characterized in that the slot has a V-shaped configuration with diverging, generally linear sides.

21. A motor vehicle as claimed in claim 19, characterized in that the slot (31) has a bottleneck (32) in a region of transition to the receiving opening (30).

22. A motor vehicle as claimed in claim 19, characterized in that the nut (14) is fastened to the rubber element (13) by one of vulcanizing, bonding and encapsulating.
