Embodiment Construction

[0035] In the following, the same reference numerals are used for identical and identically acting elements, as long as they are not mentioned otherwise.

[0036] figure 1 A schematic view of a part of a wiper blade of a windshield wiping device for a vehicle, in particular for a motor vehicle, is shown. The wiper blade comprises a longitudinally extending upper part 10 and a longitudinally extending lower part 12 which are at least partially configured to be bendable. Furthermore, a plurality of connecting elements 18 are provided for connecting the upper part 10 and the lower part 12 , wherein the connecting elements 18 are spaced apart from one another along the longitudinal extension 8 of the wiper blade 2 . figure 1 Only the connecting element 18 is shown as part of the wiper blade. The connecting element 18 is designed to enable a movement of the upper part 10 and the lower part 12 relative to each other with a component of motion along the longitudinal extension of th...

Abstract

The invention describes a windshield wiping device for a vehicle, in particular a motor vehicle, with a fastening element fastened to a drive shaft. The glass wiping device comprises a wiper blade with: an at least partially curved, elongated upper part; an at least partially curved, elongated lower part; for connecting the upper part and A plurality of connecting elements of the lower part, wherein the connecting elements are spaced apart from each other along the longitudinal extension of the blade, and wherein the connecting elements are designed to enable movement of the upper part and the lower part relative to each other with a component of motion along the longitudinal extension of the blade and the fixing part on the side of the scraper, wherein the fixing part on the side of the scraper comprises a clamping device, wherein the clamping device forms a force fit and / or a form fit with at least a part of the drive shaft by means of a bending elastic element.

Description

technical field [0001] The invention relates to a window wiping device for vehicles, in particular motor vehicles. Background technique [0002] Windshield wiping devices typically have a wiping arm or bar, in which the wiping blade moves over the windshield of the motor vehicle. In this case, the wiper blade moves between a first deflecting position and a second deflecting position. For this purpose, the wiper arm or blade is connected to the wiper motor via a drive shaft. Especially on windshields with pronounced curvature changes and in the event of large temperature fluctuations, the wiper blades tend to lose contact with the window pane. As a result, unwiped wiping areas or streaks can occur, particularly in the case of sharply bent panes. [0003] Streak formation cannot Reliably avoided in a simple manner by adjusting the pressure of the wiper arm against the windshield. Therefore, there is a need for further improvements in glass wiping equipment. [0004] Duri...
