Abstract: A windshield cleaning system with a spraying device is described, in which windshield cleaning system a jet element made of an elastic material is carried in an adjustable jet body formed in the shape of a ball. The jet element is formed with elastic lids forming a spraying mouth which is normally closed and which is located outside of the jet body. The spraying mouth is opened by the pressure of the washing liquid. With such an arrangement the direction of the spraying jet can be adjusted and the washing liquid is prevented from freezing due to the fact that the spraying mouth can be closed.

Abstract: A wiper system, which is used especially for motor vehicles and in which the pendulum-motion of at least one wiper blade is overlapped by a motion of the wiper blade in its longitudinal direction. The wiper blade can be moved by means of a gearing that can be driven via a stroking shaft coaxially running to the wiper shaft. The stroking shaft is connected to a coupler via a stroking swivelling lever, which coupler is linked to an intermediate lever that can swivellably be driven around a fixed axis by the drive motor. In order to be able to wipe a big part of the windshield of a motor vehicle, the coupler passes a dead center when the intermediate lever is swivelling from the one reversing position to the other, in which dead center the coupler reverses the direction of its motion.

Abstract: A windshield wiper, especially for motor vehicle, is described comprising a carrier yoke, a rubber element, and a resilient support for the rubber element on the carrier yoke. The resilient support of the rubber element includes a resilient strip with several resilient lugs pointing in a first direction and at least one resilient lug pointing in a second direction opposite to the first direction. Thus, the rubber element is guided and resiliently supported on the carrier yoke at both ends.

Abstract: A wiper system for motor vehicles is described in which a pivot-shaft assembly is fixed to the one end of a pipe-like carrier held by way of its other end on a stud of a motor carrier member stable in form. Wiper systems of this kind can also be produced at low costs for motor vehicles in which the assembly conditions are difficult.

Abstract: A windshield cleaning system with a spraying device is described, in which windshield cleaning system a jet element made of an elastic material is carried in an adjustable jet body formed in the shape of a ball. The jet element is formed with elastic lips forming a spraying mouth which is normally closed and which is located outside of the jet body. The spraying mouth is opened by the pressure of the washing liquid. With such an arrangement the direction of the spraying jet can be adjusted and the washing liquid is prevented from freezing due to the fact that the spraying mouth can be closed.
