Abstract: A windshield wiper device with a non-circular sweeping motion, comprises an arm carrying a blade which is caused to oscillate alternately about an axis of rotation by a drive mechanism, combined with a movement of translation such that the windshield wiper blade describes a first path during an outward stage and a second path which differs from the first during a return stage. The drive mechanism is designed to cause the longitudinal ends of the windshield wiper blade and the windshield wiper blade itself to describe paths having the shape of a curved and flattened figure 8 whose concave area faces the axis of rotation with the point of intersection of the lobes of the flattened 8 being disposed substantially in the axis of the vehicle, whereas the ends of the lobes are tangential to the angular end positions of the blade.
