Abstract

The present disclosure relates to a windscreen wiper device for a vehicle, in particular a motor vehicle, comprising a wiper blade having an elongate upper part which is designed at least partially bendable, an elongated base is configured at least partially bendable, multiple connecting elements for connecting the upper part and the lower part, wherein the connecting elements along a longitudinal extension of the wiper blade are spaced apart, and wherein the connecting elements are designed to prevent movement of the upper part and of the lower part relative to one another with a movement component along the longitudinal extension to allow the wiper blade, and a flexible member, which is adapted ; a force substantially perpendicular to the longitudinal extension of the wiper blade to provide, wherein the force of at least part of a contact pressure of the wiper blade on a disk of the vehicle provides, wherein said wiper blade in its longitudinal extension a first portion and a to the first portion adjoining the second portion, wherein the first portion substantially from a rotational axis of the wiper device extends, and wherein the flexible member is arranged in the first section.

Description

technical field [0001] The present disclosure relates to a windshield wiper device for a vehicle, in particular a motor vehicle. Background technique [0002] Windshield wiper devices typically have a wiper arm or a wiper lever, wherein a wiper blade moves over the windshield of the motor vehicle, wherein a wiper lip is fastened to the wiper blade. The wiper arm is alternately moved between a first steering position and a second steering position. For this purpose, the wiper arm is connected to the wiper motor via a transmission shaft. Especially on windshields with sharp changes in curvature, the wiper blade with wiper lip tends to lose contact with the window pane. As a result, unscratched scratched areas or striations can occur, especially for strongly curved panes. [0003] In addition, the wiper blade should exert a uniform and sufficient contact force (supporting force) on the window pane of the vehicle over its length in order to be able to achieve a good wiping ef...
