A wiper arm mounting system for mounting a wiper arm rigidly and removably to a drive shaft includes a mounting part and a threaded fastening element that is realized in the form of a fastening nut or fastening screw with the fastening element acting upon the drive shaft in the axial direction. The fastening element is held on the mounting part in captive fashion at least approximately in the mounting position, such that the wiper arm can be pulled off the drive shaft (8) by means of rotating the fastening element.

As to a reciprocating stroke wiper system for motor vehicles with a piston movably guided in a housing a projecting arm unrotatably fixed to the piston and comprising a guiding fork is provided as a protection against twisting, which projecting arm is guided along a guiding element fixed to the housing. According to the invention a rod with circular cross-section is used as a guiding element, which rod is arranged at an angle towards the axis of the piston so that the guiding areas of the guiding rod and of the guiding fork touching each other are displaced crosswise to them during the motion so that the effective guiding area is enlarged and thus wear is reduced.

In a reciprocating wiper system for motor vehicles with a piston adjustably guided in a housing a slide fixed on the housing in a torsionally firm way is provided as a protection against twisting, the slide is longitudinally guided on a guide element fixed to the housing. To compensate for unavoidable tolerances of position and shape of the guide elements and the slide a calotte-shaped bearing body is fittingly guided on the guide element. The bearing body is movably mounted with play in the radial direction in a calotte-shaped receiver on the slide.

A windshield wiper unit with a wiper arm of telescopic construction which has a housing driven to and fro round an axis of rotation by a driving motor and a slide movable in relation to the housing, this slide being displaceable by a crank assembly is so designed that the various bearings are subjected to little load and so that compact construction is possible. This is achieved by having the connecting rod belonging to the crank assembly above or below the slide and linked to the slide between the two bearings for it and by having the distance between the two bearings at least as great as the stroke of the slide.

In a windshield wiper system for motor vehicles the contact pressure of the wiper onto the window is adjustable while the wiper is moving. For this purpose a multi-part actuator driven by an electromotive adjusting device and guided in a bore of the wiper shaft is axially displaced. The multi-part construction of this actuator compensates for faulty alignment, so that the adjusting mechanism operates with a good efficiency and enables rapid adjusting times.

A replacement assembly for a wiper blade for cleaning the windshield of a motor vehicle includes an elastic wiper blade assembly that has a top part and a wiper lip, with one respective elastic rail inserted into two lateral longitudinal grooves in the top part and retained therein by a retaining clip. An end piece on the end and the retaining clip both hold the elastic rails in the longitudinal grooves. The end piece is attached to one end of the wiper blade assembly, with said end piece securing the wiper blade assembly on the wiper blade frame in the longitudinal direction with the end to insure simple and safe handling of the replacement assembly.

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.

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.
摘要:
A windshield wiper blade for a vehicle windshield wiper device features a wiper blade rubber made of a resiliently deformable material which exhibits a backing to which two parallel wiper lips are connected by means of a flexible neck and an intensive-cleaning element attached to each of the mutually remote longitudinal sides of the wiper lips, wherein the intensive-cleaning element leading relative to the direction of motion of the wiper blade rubber and the wiping edge of the trailing wiper lip contacts the windshield. In order to improve the wiping quality of the wiper blade rubber, both wiper lips exhibit an essentially triangular cross-section of standard wiper blade rubbers and are connected to the backing in such a way that, when the wiper is operating, each can be supported on the bottom side of the backing with a shoulder lying at the rear in relation to the direction of motion. In another variant designed to improve the wiping quality of the wiper blade rubber, the intensive-cleaning elements are formed by numerous individual segments mutually spaced along the length of the wiper blade rubber, with the segments of one intensive-cleaning element offset in the longitudinal direction relative to the segments of the other intensive-cleaning element.
摘要:
A drive mechanism for at least two windshield wipers of a vehicle, in particular of an automotive vehicle, with a driving motor (1) which includes a gear unit accommodated in a gear casing (2) which is closed by means of a cap and where, on the end of an output shaft (3) protruding from the gear casing (2), a motor crank (4) is fastened in a torsion-resisting manner for driving the wiper shafts (8) of the at least two wiper bearings (5, 11) via rods, is to be improved so that, on the one hand, it is easily adaptable to the space or installation conditions prevailing on the vehicle while, on the other hand, due to a reduced number of components, it can be manufactured at lower cost as compared to known drive mechanisms. This is achieved in that the one wiper bearing (5) is an integral part of the gear casing (2) or of the cap thereof and in that at least one further wiper bearing (11) is fastened on a carrier (12) of selectable length which, on its part, is fastened on the gear casing (2) or on the cap thereof.
