Windscreen wiper and a motor vehicle comprising such windscreen wiper

Abstract

The present invention relates to a motor vehicle's windscreen wiper, that includes a wiper blade and driving system; where the driving system includes a wiper motor, a wheel plate that pivots about a central rotational axis; where the wheel plate's angular position is associated with the wiper blade's angular position; where a parking cam on the wheel is associated with two parking contact springs with parking electrodes that press against the wheel plate surface under a resilient bias of the parking contact spring; where a parking trace is defined by a track slid by the parking electrode on the wheel plate during the wheel plate's rotation such that distances between the contact spring parking electrodes and the wheel plate's central rotation axis is substantially equal to each other such that traces of the parking electrodes generally coincide with each other; where the invention further includes a single-trace parking cam consisting of only one arc-segment such that the parking trace substantially follows a center arc by; where application of the single-trace cam is able to achieve the wiper parking function of the windscreen wiper in a compact and cost-effective manner.
