Windshield wiper for land, sea and marine vehicles, in particular for trucks (lorries) and passenger automobiles

Abstract

A windshield wiper, in particular for trucks (lorries) and passenger automobiles, comprises a device for increasing the cleaning intensity which is determined, in known wipers, merely by the sweeping force of the wiping blade; this cleaning intensity-increasing device comprises one or several rotating brush rollers which are associated with the wiping blade borne by the wiping arm--of which blade there can be several arranged thereon. The brush roller can be oriented parallel, or at an angle, with the wiping blade. Or, the cleaning intensity-increasing device comprises a plurality of plate brush units and one or several rows of pinions in engagement with one another, or tangentially engaging friction wheels, serving as driving device for the said plate brush units. The plate brushes in the units have their bristles turned against the windshield and are adapted for being driven alternatingly in opposite senses of rotation. This drive can be effected either by the wiper motor via appropriate transmission elements which always switch to the opposite sense of rotation at each sweep end position of the wiper lever, or they can be driven in a constant sense of rotation by a separate electric motor.
