Abstract: A drive motor for at least one wiper arm intended to wipe a glazed surface of a motor vehicle is disclosed. The motor includes a cam surface linked in concentric rotation with a rotary shaft of the drive motor, and static cam reading means able to cooperate with said cam according to the angular positions occupied by said cam to generate electrical control signals varying as a function of the angular position of the wiper arm on the glazed surface. The cam has a first circular conductive track, a second semi-circular conductive track concentric to the first conductive track and connected to same via a conductive bridge, in which the static reading means are formed by three sliding contacts able to make and break electrical contact with respectively the first and second conductive tracks and the conductive bridge depending on the angular positions occupied by said cam.

Abstract: The invention relates to a wiper system (1) for wiping a glazed surface of a motor vehicle having a washer system (3) able to be used in combination with a reservoir (5) containing a washer fluid, said wiper system comprising—a drive motor (7) for driving at least one wiper arm,—a pump (11) intended to be fluidly connected firstly to said reservoir (5) and secondly to at least two spray nozzles at least one of which is able to deliver a jet of fluid to the windshield of a vehicle and at least another of which is able to deliver a jet of fluid to the rear screen of a vehicle, and—a switch (17) having at least a first position for supplying said at least one spray nozzle able to deliver a jet of fluid to the windshield and a second position for supplying said at least one spray nozzle able to deliver a jet of fluid to the rear screen,—the pump (11) being a two-way pump capable of being driven in two opposite directions of rotation to supply one or other of the spray nozzles under the control of said switch (17)

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.
