Abstract The present invention relates to a device for cleaning the glass of a vehicle headlight. The device comprises a gear box placed in front of the glass and having a shaft supporting a rotatable wiper blade. The gear in the gear box is operated by a motor via a flexible cable. The device is chiefly characterized in that the motor is arranged to operate the cable at a high speed, that the worm gear in the gear box is arranged to provide in one step the reduction required to produce a speed of rotation suitable for the wiper blade, and that a stopper rotating synchronously with said wiper blade is provided to actuate the motor to stop said wiper blade in a predetermined fixed position. The shaft of the gear box is journalled in a boss, or the like, which is glued or otherwise secured on the outside of the glass.
A device for cleaning the glass of a vehicle headlight, comprising a gear box in front of the glass, a rotatable shaft in the gear box supporting a rotatable wiper blade, a gear in the gear box driven by a motor via a flexible cable, the motor driving the cable at high rpm via a distributor gear, a worm gear in the gear box providing in one step the reduction required to produce a speed of rotation suitable for the wiper blade, and a stopper rotating synchronously with said wiper blade and mounted in the vicinity of the motor and actuating the motor to stop said wiper blade in a predetermined fixed position.
