Abstract

The invention relates to an adapter unit which is provided for coupling, in particular releasably coupling, a wiper blade to a wiper arm, having a wind deflecting surface which is designed to deflectinflowing air and press the wiper blade against a vehicle windshield. According to the invention, the wind deflecting surface has at least one first sub-surface and a second sub-surface, wherein the first sub-surface has a different orientation than the second sub-surface and / or the first sub-surface has a different geometry than the second sub-surface.

Description

technical field [0001] The invention relates to an adapter unit, which is provided for coupling, in particular for releasably coupling, a wiper blade to a wiper arm and has a windshield surface. Background technique [0002] A wiper device has already been proposed which comprises a wiper arm and a wiper blade as well as an adapter unit for releasably coupling the wiper arm to the wiper blade. Such wiper systems have the disadvantage that the wiper arm always has to exert a high pressing force in order to press the wiper blade against the vehicle window in order to ensure adequate wiping performance. Contents of the invention [0003] The invention relates to an adapter unit, which is provided for coupling, in particular releasable coupling, of a wiper blade to a wiper arm, with a barrier provided for blocking the passing air and pressing the wiper blade against the vehicle window Windshield surface, characterized in that the windshield surface has at least a first partia...
