Abstract
The present invention relates to a windscreen wiping device (100) for a vehicle, comprising a wiper blade (2) with an elongate upper part (10) and an elongate lower part (12), which are configured to be at least partially bendable. Furthermore, a plurality of connecting elements (18) for connecting the upper part (10) and the lower part (12) are provided, said connecting elements being spaced apart from one another along a longitudinal extent (8) of the windscreen wiping device and being designed to permit a movement of the upper part (10) and of the lower part relative to each other with a movement component along a longitudinal extent (8) of the windscreen wiping device. Furthermore, the windscreen wiping device has a pretensioning device (50), wherein the pretensioning device has a force-absorbing element (32) which is connected to a force transmission element (33) such that, in the event of a dynamic effect on the force-absorbing element (32) in the direction of the elongate lower part (12), a rotational movement of the force transmission element (33) is brought about, thus resulting in a movement of the elongate upper part (10) relative to the elongate lower part with a moveme…
