The invention relates to a method for reducing material creep processes of a windshield washer device. The method comprises the providing () of a windshield washer device for a vehicle. The windshield washer device comprises a wiper blade () having an elongated top part () and an elongated bottom part (), which are designed to be at least partially bendable. Furthermore, there is a plurality of connecting elements () for connecting the top part and the bottom part, wherein the connecting elements are spaced apart from each other along a longitudinal extension () of the wiper blade. The connecting elements () are designed to enable a movement of the top part () and the bottom part () relative to each other, having a movement component along a longitudinal extension () of the wiper blade. The method further comprises a loading () 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%.

Windshield wiper device having improved creep behavior

The present invention relates to a windscreen wiping device () for a vehicle, comprising a wiper blade () with an elongate upper part () and an elongate lower part (), which are configured to be at least partially bendable. Furthermore, a plurality of connecting elements () for connecting the upper part () and the lower part () are provided, said connecting elements being spaced apart from one another along a longitudinal extent () of the windscreen wiping device and being designed to permit a movement of the upper part () and of the lower part relative to each other with a movement component along a longitudinal extent () of the windscreen wiping device. Furthermore, the windscreen wiping device has a pretensioning device (), wherein the pretensioning device has a force-absorbing element () which is connected to a force transmission element () such that, in the event of a dynamic effect on the force-absorbing element () in the direction of the elongate lower part (), a rotational movement of the force transmission element () is brought about, thus resulting in a movement of the elongate upper part () relative to the elongate lower part with a movement component along a longitudinal extent () of the windscreen wiping device.

Furthermore, a plurality of connecting elements () for connecting the upper part () and the lower part () are provided, said connecting elements being spaced apart from one another along a longitudinal extent () of the wiper blade () and being designed to permit a movement of the upper part () and of the lower part relative to each other with a movement component along a longitudinal extent () of the wiper blade (). Furthermore, a multiplicity of the plurality of connecting elements () are connected to the upper part () via a first film hinge in each case and to the lower part () via a second film hinge in each case. Furthermore, a film-hinge stop device is provided in order to limit a rotational movement of the connecting elements () relative to at least one part from the elongate upper part and the elongate lower part.

The present invention relates to a windscreen wiper device () for a vehicle, with a fastening element (). The windshield wiper device () includes a wiper blade () with an elongated upper part () and an elongated lower part () which is at least partially designed to bend. Furthermore, a plurality of connecting elements () for connecting the upper part () and the lower part () is provided, wherein the connecting elements () are spaced apart along a longitudinal extension () of the wiper blade (). The connecting elements () are designed to enable a movement of the upper part () and the lower part () relative to one another with a movement component along a longitudinal extension () of the wiper blade (). Furthermore, the wiper blade () comprises a wiper blade-side fastening part (). The wiper blade fastening element () comprises a securing element () into which the fastening element () is insertable and which is designed to engage the fastening element () to force-fit or form-fit.
