Embodiment Construction

[0029] figure 1 The window wiper device 10 according to the invention is shown in a perspective view. It essentially consists of a blank tube 12, which has two ends, to which a wiper bearing 14 is fastened in each case. In each of the wiper bearings 14 is mounted a wiper shaft 16 , to which a wiper arm (not shown here) with a wiper blade is fastened. The end of the wiper shaft 16 protrudes from the vehicle body in the assembled state. The wiper shaft 16 is respectively driven by a crank 18 , and the crank is connected with a driving motor 24 and a motor transmission box 26 through a push rod 20 and a motor crank 22 . The wiper bearing 16 comprises at least one bearing section 28 which supports the wiper shaft 16 and a fastening element 30 with which the wiper bearing can be fastened to the vehicle body.

Abstract

A windscreen wiper device, in particular for motor vehicles, has at least one wiper bearing (14), which supports at least one wiper shaft (16) in its bearing section (28), and a Fixing element (30) on the car. At least one first element ( 36 ) is provided here for the movable connection between the bearing section ( 28 ) of the wiper bearing ( 14 ) and the fixing element ( 30 ), said first element ( 36 ) being a membrane Hinges in which at least one other element (40) for locking the securing element (30) to the support segment (28) is provided, said further element (40) being provided with circular arc multistage teeth (54) the locking element.

Description

technical field [0001] The invention relates to a windshield wiper device. The windshield wiper device has at least one wiper bearing, which supports at least one wiper shaft in a bearing section and is provided with a fastening element for fastening. Background technique [0002] Known numerous windshield wiper devices, known for example by EP-A-073 9792, they have a wiper bearing, and it supports a wiper shaft in a support section and has a wiper shaft that is used to be fixed on the automobile. fixed components. Here the fastening element is provided with a predetermined breakout point, which has a reduced cross-section. In the event of a strong impact on the wiper shaft protruding from the body, the windshield wiper system separates from the vehicle body at a predetermined disconnection point. As a result, the wiper shaft can be pushed into the vehicle interior in order to reduce the risk of injury to pedestrians if they are hit. The problem here is that the windshie...
