Abstract

The invention relates to a windshield wiper device (50, 70) for a vehicle, in particular a motor vehicle. The windshield wiper device comprises a wiper blade (51, 71) with an elongated upper part (52, 72) which is designed to be at least partly flexible, an elongated lower part (53, 73) which is designed to be at least partly flexible, and multiple connection elements (18) for connecting the upper part (52, 72) and the lower part (53, 73). The connection elements (18) are mutually spaced along a longitudinal extension (8) of the wiper blade (51, 71), and the connection elements (18) are designed to allow the upper part (52, 72) and the lower part (53, 73) to move relative to each other with a movement component along a longitudinal extension (8) of the wiper blade (51, 71), a cross-section of the wiper blade (51, 71) perpendicular to the longitudinal extension (8) of the wiper blade being substantially trapezoidal.

Description

[0001] The invention relates to a windshield wiper device for a vehicle, in particular a motor vehicle. Background technique [0002] A windshield wiper device typically has a wiper arm or a wiper lever, a wiper blade being moved over the windshield of the motor vehicle, and a wiper lip to which wiper blade is fastened. 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 drive shaft. [0003] In the case of windshield wiper devices known from the prior art, it can occur during fast driving, in particular on windshields with severe curvature changes, that the wiper blade loses contact with the windshield. Streaks or fog may thus occur. Under extreme weather conditions, for example, high demands are placed on windshield wiper devices with regard to overcoming and removing water and / or snow from the windshield. The windshield wiper devices known from the prior...
