Embodiment Construction

[0019] At its rear, a motor vehicle has a windshield 2 that can be swiveled in a swivel direction 1 and its associated wiper device. A wiper 5 for wiping the windshield 2 is arranged on the outer side 3 of the windshield 2 and is articulated via a wiper arm 4 . For driving the wiper 5 , a conventional motor-gear unit 6 is provided, which has bore holes 7 in its edge for screwing the motor-gear unit 6 to the vehicle body. Opposite the housing of the motor-gear unit 6 protrudes a portion of a rotatably driven drive shaft 9, on the outward end of which a clutch portion 10 is fixed. The glass 2 has a circular recess 11 which is opposite the clutch part 10 in the closed position shown in FIGS. 2 and 3 . Recess 11 accommodates an essentially annular bearing bush 12 , which is connected to glass 2 . A wiper shaft 14 pivotable about an axis 13 is supported in the bearing bush 12 , which can also be guided displaceably along the axis 13 . On the end of the wiper shaft 14 facing the ...

Abstract

A wiper device for wiping, in particular a movable windshield (2) on a motor vehicle, equipped with: a rotatably driven first clutch part (10) for connection to a fixed motor-gear transmission The driving shaft (9) that can be driven by rotation at the back of the unit (6); a second clutch part (15), which is connected with a wiper shaft (14) for driving a wiper (5), and can be used together with the gear The windshield (2) moves together and can engage with the first clutch part (10) in such a way as to transmit torque and center the wiper shaft (14) against the drive shaft (9); an anti-overload protection device, For limiting the torque that can be transmitted between the first clutch part (10) and the second clutch part (15), the protection device is integrally formed with the first clutch part (10) and / or the second clutch part (15) of.

Description

technical field [0001] The invention relates to a wiper device for wiping movable windshields, in particular of motor vehicles. Background technique [0002] A wiper device for a windshield is known from DE 33 13 057 A1. In this arrangement, the wiper arm is fastened together with the associated mount on a deflectable windshield. The motor-gear transmission unit is fixedly connected to the vehicle body. For centering, a centering pin is provided on the body side, which can engage with a lever provided on the windshield side with a centering recess. Off-centered to the lever on the vehicle body side, a spring-loadable pin is provided at the end of a rotatably driven arm, which pin can be connected to a receiving hole for torque transmission provided on the lever. Mesh. Overall, such devices are structurally complex, comprising a large number of parts. Contents of the invention [0003] The object of the present invention is to provide a wiper device for wiping a movabl...
