ABSTRACT:
The present invention is concerned with retractable windshield wiper installations for vehicle, having a foldable wiper arm.
The installation according to the invention includes a wiper arm comprising a blade carrier and a support arm, in which the blade carrier is moveable between a deployed position and a position in which it is folded back against the support arm. The wiper arm is driven in rotation by a drive spindle mounted on a support plate. A deployment mechanism is actuated by a deployment motor so as to move the blade carrier from its folded back position to its deployed position and vice versa. The deployment motor is fixed on the support plate so that it is not driven in rotation by the drive spindle. In this way, the inertia of the assembly which is driven in rotation during the wiping operation is very much reduced by comparison with installations in which the deployment motor is carried by the blade carrier support arm.
