Windshield wiping device and method for the operation thereof
First Claim
1. A windshield wiping device for a windshield (11) of a motor vehicle, the windshield (11) having a surface, the motor vehicle having a center and a hood positioned forwardly of the windshield (11), the device comprising a wiper arm (1) connected to a wiper bearing pin (3) having an axis, the wiper arm (1) being driven via the wiper bearing pin (3), a lifting angle (α
- ) of the wiper arm (1) being defined between a first portion of the wiper arm (1) and a second portion of the wiper arm (1) and being in a plane perpendicular to the surface of the windshield (11), the wiper bearing pin (3) being positioned to one side of the center of the vehicle and intersecting an extension of the surface of the windshield (11), characterized in that the wiper bearing pin (3) has a geometric orientation of its axis relative to a line generally perpendicular to the extension of the surface of the windshield (11), the geometric orientation being toward the hood and toward the center of the vehicle such that, during a wiping movement of the wiper arm (1) across windshield (11), a change in substantially one direction of a value of the lifting angle (α
) of the wiper arm (1) is carried out.

Abstract
Disclosed is a windshield wiping device for a motor vehicle. A wiper arm is connected to a wiper bearing pin, the wiper arm being driven via the wiper bearing pin. The inventive windshield wiping device is characterized in that the wiper bearing pin is geometrically oriented in such a way that the lifting angle of the wiper arm changes in substantially one direction when the wiper arm performs a wiping movement across a windshield.
