Embodiment Construction

[0019] figure 1 is a perspective view of a windshield wiper device 10 according to the invention.

[0020] The wiper device 10 comprises a plurality of components 12 , 14 , 16 , 18 , 20 , in particular a support tube 12 , at each end of which a wiper bearing 14 is fastened. A wiper shaft 16 is mounted in each case in the wiper bearings 14 . These wiper shafts can be moved back and forth by means of a transmission 20 via the drive 18 . The transmission mechanism 20 includes a driven crank 22 , which can realize a reciprocating movement or a rotary movement via the drive mechanism 18 . Two pushrods 24 are articulated to the output crank 22 , which at their ends facing away from the drive crank 22 are each able to effect a pivoting movement of the drive crank 26 . To this end, the push rod 24 is connected to the drive crank 26 via a ball joint 28 . The drive crank 26 is in turn non-rotatably connected to the wiper shaft 16 , so that the wiper shaft achieves a reciprocating mo...

Abstract

The invention relates to a windshield wiping device (10), especially for a motor vehicle, which device comprises a plurality of parts (12, 14, 16, 18, 20), namely in particular a support tube (12) that carries at least one wiper bearing (14) which receives at least one wiper shaft (16). The windshield wiping device (10) is also provided with a transmission (20) that sets the wiper shaft (16) in radial motion by means of a drive (18). According to the invention, the device is provided with a deformation element (38, 42) which can be deformed by the impact of a defined axial force (F) on one of the parts (12, 14, 16, 18, 20) of the windshield wiping device (10).

Description

technical field [0001] The invention relates to a wiper device, in particular for motor vehicles. Background technique [0002] As everyone knows, there are many kinds of wiper devices, which comprise a plurality of parts, such as a support tube, which houses a wiper bearing by supporting a wiper shaft. These wiper devices also have a gear mechanism, which enables a radial movement, in particular a pivoting movement, of the wiper shaft via a drive mechanism. [0003] Furthermore, for example from EP-A-0 739 792 a wiper device with a theoretical breaking point is known, so that when a pedestrian collides with the wiper shaft of a motor vehicle, the wiper device is released so that the wiper shaft can penetrate into the car interior. Depending on the magnitude of the direction of the axial force acting on the wiper shaft, however, this theoretical breaking point is not always optimal. Furthermore, problems can arise if a pedestrian hits the body in the region of the wiper s...
