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

Abstract: The invention relates to an adapter (15) intended for connecting a wiper blade to an end portion (23) of a drive arm, including a first wall (16) and a second wall (19), the first wall (16) and the second wall (19) being interconnected by at least one linking wall (22), characterised in that the linking wall (22) intersects a median longitudinal plane (P2) of the adapter (15), and in that the first wall (16) has a first length (L1) which is greater than a second length (L2) of the second wall (19), the first length (L1) and the second length (L2) being measured according to straight lines parallel to the median longitudinal plane (P2), and in that the first wall (16) is provided with a means (33) for locking and/or unlocking the adapter (15) on the end portion (23).

Abstract: A motorised reduction gear unit, especially for a vehicle screen wiping system, comprises a hollow casing closed by a cover plate, and, within the casing, a toothed wheel which is rotatable about an axis and which carries a pin parallel to the toothed wheel axis and eccentric with respect to the axis. This pin drives a crank and connecting rod unit to convert continuous rotation of the toothed wheel into an alternating motion of an output shaft. The output shaft is provided with braking means for applying braking action to its rotation.
