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: An arrangement for fixing a wiper device for a motor vehicle includes at least one stand for guiding and fixing a drive shaft that extends axially in a substantially vertical direction. The stand includes a barrel in which the shaft is guided in rotation, and a horizontal base plate for fixing the stand to a structural element of the vehicle, by a damper block made of an elastically deformable material. The damper block is fixed to the structural element by a fixing element, which includes a vertical rod that passes through the damper block and is connected to the structural element, and an element for locking the damper block on the structural element. The rod and locking element are connected by connection means for enabling the rod and locking element to disconnect, through downward sliding of the locking element with respect to the rod, when subjected to a violent impact.

Abstract: A method is disclosed for assembling a windscreen-wiper mechanism having a support plate on an internal face of a body structure element that extends globally vertically at a rear of a motor vehicle. The method includes the steps of positioning the support plate relative to the internal face of the body structure element and joining the plate to the internal face of the body structure element. The positioning step includes moving the plate relative to the body structure element along a first direction, and the joining step includes rotating the plate about the first direction.

Abstract: The wiper motor unit for a motor vehicle includes a case comprising a base and a cover adapted to close the base and define an inside enclosure of the case, the motor unit having a duct adapted to convey a liquid, isolated from the inside enclosure, and defined by one element of the base and the cover, the motor unit further including an outlet shaft. The duct extends outside the shaft.

Abstract: A supporting base for a wiper mechanism comprising a plate assembly forming a base for the components of the mechanism, particularly wiper drive members, and further comprising means for attaching the base to the bodywork of a vehicle, and at least one elongate structural member attached to the plate assembly and including a free end section supporting a bearing for a wiper shaft. Said plate assembly consists of two stacked plates of which the first plate is attached to the structural member while the other plate comprises said means for attaching the base to a part of the bodywork of the vehicle, and means are provided for joining said plates together.
