Abstract
A screen wiping apparatus, in particular for an opening window of a motor vehicle, comprises an electric motor which drives at least one screen wiper in oscillating motion between two reversal positions, namely a fixed inner stop position and a fixed outer stop position. In addition, the blade is able to be retracted into a parked position which lies away from the window, when the window is to be opened. The apparatus includes a control system whereby the power supply voltage to the motor is variable by adjustment between a zero voltage and a maximum or full power voltage. The control system includes means for reducing the power supply voltage to the motor when the screen wiper passes from the fixed inner stop position to the off-window parked position.
