Pretensioning device for a windscreen wiping device

Abstract

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.
