Abstract
The invention relates to a method for reducing material creep processes of a windshield washer device. The method comprises the providing (201) of a windshield washer device for a vehicle. The windshield washer device comprises a wiper blade (2) having an elongated top part (10) and an elongated bottom part (12), which are designed to be at least partially bendable. Furthermore, there is a plurality of connecting elements (18) for connecting the top part and the bottom part, wherein the connecting elements are spaced apart from each other along a longitudinal extension (8) of the wiper blade. The connecting elements (18) are designed to enable a movement of the top part (10) and the bottom part (12) relative to each other, having a movement component along a longitudinal extension (8) of the wiper blade. The method further comprises a loading (202) of the windshield wiper device before final assembly of the windshield wiper device on a vehicle such that, after final assembly of the windshield wiper device, a primary creep behavior of the windshield wiper device is substantially reduced, in particular by at least 80%.
