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.

Wiper system for a vehicle with a screen wash system

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.
