The invention relates to a screen wiper (1) for a motor vehicle screen (6) comprising a support frame (2) of principal longitudinal orientation, having lower means exhibiting a wiper blade (4), the said support frame (2) being intended to be caused to move between two end positions along a predetermined trajectory in a wiping cycle of the screen (6), and a device (7, 8) for spraying cleaning liquid comprising at least one first set of spraying orifices aligned in the said principal longitudinal orientation for at least one part of a first side of the wiper in such a way as to permit the spraying of washing liquid in front of the wiper in relation to the wiping movement. According to the invention, the spraying orifices are distributed over the said first side with a non-constant spacing, the distance separating two successive orifices being selected in such a way that the portion of the surface of the screen that is effectively sprayed by a spraying orifice in the course of a wiping cycle is substantially equal to the same target value for all the spraying orifices of the first set. |
