Abstract

Disclosed is a windshield wiper device (10), comprising a wiper bearing (16) which is essentially composed of a molded tube (18) that can be fastened to a motor vehicle by means of a fastening element (20). A wiper shaft (22) to which a wiper lever can be fastened is positioned in the molded tube (18). A predetermined breaking point (32) is provided on the fastening element (20) in such a way that the wiper bearing (16) is able to dip into the interior of the motor vehicle in case a defined and essentially axial force acts on the wiper shaft (22). The predetermined breaking point (32) is embodied as a hole in this case.

Claims

1. Windshield wiper device (10) for a motor vehicle having an interior, comprising a wiper bearing (16), a wiper shaft (22) positioned in a molded tube (18) of the wiper bearing (16) on which a wiper lever can be fastened, and a fastening element (20), which is a one-part piece with the wiper bearing (16) and is used to fasten the windshield wiper device (10) to the motor vehicle, the fastening element (20) being a plate-like projection defining a plane, and the fastening element (20) having a predetermined breaking point (32) such that the wiper bearing (16) is able to dip into the interior of the motor vehicle in case a defined, essentially axial force acts on the wiper shaft (22), characterized in that the predetermined breaking point (32) includes a hole having a longitudinal axis in the plane of the fastening element (20).

2. Windshield wiper device (10) according to claim 1, characterized in that the fastening element (20) is a one-part piece with the molded tube (18).
