Abstract
A wiper (14) for wiping a window pane (12) of a motor vehicle is provided, having a drive shaft (16) that can be driven by a motor, and a wiper lever (18) connected to the drive shaft (16) for moving a wiper blade. The wiper lever (18) is flexibly bendable. A maximum bending angle (20) of the wiper lever (18) around a bending axis extending perpendicular to the drive shaft (16) is limited by a limit stop (32) to bending of the wiper lever (18) in the range of elastic deformation. The limit stop (32) makes stop contact at the maximum bending angle (20) and can keep the deformation of the wiper lever (18) reliably in the range of elastic deformation, thus reducing the risk of damage to wipers (14).
Claims10
A wiper for wiping a window pane of a motor vehicle, the wiper having a drive shaft that can be driven by a motor, and a wiper lever connected to the drive shaft for moving a wiper blade, the wiper lever being flexibly bendable,
- wherein a maximum bending angle of the wiper lever around a bending axis extending perpendicular to the drive shaft is limited by a limit stop to bending of the wiper lever in a range of elastic deformation, and a counterstop projecting from the drive shaft on a rear region of the wiper lever facing away from the wiper blade and configured to engage the limit stop.
A wiper for wiping a window pane of a motor vehicle, the wiper having a drive shaft that can be driven by a motor, and a wiper lever connected to the drive shaft for moving a wiper blade, the wiper lever being flexibly bendable, a cover connected to the wiper lever and covering the wiper lever,
- wherein a maximum bending angle of the wiper lever around a bending axis extending perpendicular to the drive shaft is limited by a limit stop formed on the cover to limit bending of the wiper lever in a range of elastic deformation, and the limit stop of the cover is configured to make stop contact with a region of the wiper lever that does not bend.
