Abstract: In order to configure a connecting link for articulated connecting with a wiper arm and with a control arm so that it can be connected in a dependable manner with little effort to the widely used type of wiper blade, in which an attachment bolt extends transverse to the longitudinal direction of the wiper blade in an upward open region between the two side cheeks of the wiper blade support bar, which stand apart from each other and run parallel to each other; the connecting link has a one-piece base element with a back part and a connecting part set at a distance from it in the direction of the pane to be wiped, said connecting part is designed to snap into the attachment bolt of the wiper blade support bar, and at the back part there are mutually spaced connecting elements, in particular articulated bolts attached to pivot the wiper arm and the control arm.

Abstract: A wiper arm, especially for motor vehicles, with a wiper rod and a unit having a jacket and a hose to supply a washing nozzle with washing solution to wiper rod. The single piece, flexible material unit securely holds the hose to the wiper rod therein reducing installation cost. A wall of the unit is made divided, and opposing portions of wall are designed as a closure.

Abstract: A windshield-washing system with a wiper rod manufactured from flat strip steel of defined width and thickness that supports, at its free end, a bearing device with a bearing bushing for an articulation pin and oriented perpendicular to the width. For an economical production of such wiper arms with flawless functionality, the bearing device, consisting of a bearing bushing with laterally projecting fastening sleeve, is produced as a plastic part, pushed onto the free end of the wiper rod and locked in place thereon.

Abstract: A nozzle element covering open channels through the use of a removable cover forming thus nozzles for a windshield washer system. A preferably flat seal elastically covers several apertures. Advantageous embodiments concern the division of the nozzle unit and the allocation of the seal to the channels ending at the apertures.

Abstract: An attachment for a noise-and-vibration dampening fixing of a windshield wiper system to a vehicle body comprises a fastening eye with a circular aperture for receiving a rubber-elastic, hollow, cylindrical, noise-and-vibration dampening element with circumferential annular groove on its outside surface. Good stability of the attachment and its easy assembling are achieved in that, proceeding from the circular aperture, an open break extends through an edge, raised in an approximately perpendicular manner, so that a web is fastened on yoke tongues of a resulting yoke opening and bridges the yoke opening. The dampening element is insertable sideways through the yoke opening as far as into the aperture.

Abstract: A system for fixating a shaft in its bearing casing as well as in a wiper installation the shaft is fixated in its bearing in that the annular gap between the shaft and the bearing is filled by the injection of a plastic material rendering optimum sealing and load bearing qualities.

Abstract: In order to provide the possibility of simplifying the varieties with relation to the type of wiper blades, the invention is directed toward developing a cost-effective and easy to handle connection piece for connecting a link cap at its wiper rod with aligning borings in its wiper rod comprising parallel side walls with the carrier shaft of a wiper blade, which comprises in a fastening section, which is open at its top, a fastening bolt between its parallel side cheeks. The connection piece comprises an upper connection part for a fixed connection with the link cap of the wiper arm and the bottom part for connecting the carrier shaft of the wiper blade with the fastening section of the carrier shaft in a locking and oscillating manner.

Abstract: A windshield washing system, especially for motor vehicles, is provided with a wiper shaft, on which a wiper arm can be non-rotatably fastened and which wiper shaft includes an axial bore in order to receive a line made from form-stable plastic material with at least one channel, through which at least one washing nozzle moving in pendular motion with the wiper arm during the wiping process can be provided with washing liquid. In order to ensure that the wiper shaft takes along the line, the line is form-fittingly connected with the wiper shaft in the swivelling direction of said wiper shaft at the end of the wiper shaft turned away from the wiper arm.

Abstract: A wiper arm with a wiper rod, at the one end of which a wiper blade is fixed.The wiper rod is provided with a coating, onto which coating a hose channel is formed. Furthermore, it is possible to fix additional hose supports onto the wiper rod or onto the joint.

Abstract: This invention refers to a wiper system for windshields of motor vehicles. This wiper system comprises a wiper arm which can be attached to an oscillatorily drivable wiper shaft by way of an attachment piece. The wiper arm comprises a joint piece being essentially U-shaped in cross-section, flexibly embracing the attachment piece with its planar walls, and a cover for the attachment piece essentially U-shaped in cross-section and embracing the attachment plane with its planar walls. Furthermore, the wiping system is provided with a fluid line, which is guided along the wiper arm in order to supply a washing nozzle with washing fluid. The fluid line is easily assembled in the wiper arm at the attachment piece through a depression in which the fluid line extends. Beyond the depression in the attachment piece the fluid line extends through the wiper arm by being surrounded by a planar wall of the joint piece or the cover and a pressure spring.

Abstract: The invention relates to a wiper and washing system including a tube with two separate channels, a nozzle head with at least two washing nozzles, one of which is connected to the one channel and the other of which is connected to the other channel of the tube, and a connecting piece from which the tube starts off. In order to avoid wrong assemblies, coding the connections between the tube and the nozzle head as well as between the tube and the connecting piece are provided on the tube on the one hand, and on the nozzle head or on the connecting piece on the other hand.

Abstract: A windshield wiper system includes two windshield wipers of which each is mounted on a separate wiper shaft and may be driven to and fro by a separate motor between an inner reversing position and an outer reversing position, which windshield wipers are at least partially superposed in their inner reversing position and rotate in opposite directions through one wiping cycle. The two windshield wipers are moved without collision even though they wipe an overlapping area. The first windshield wiper is driven by its associated motor with a greater angular velocity of the output shaft than the second windshield wiper is driven by its motor. In addition the first windshield wiper is stopped for a predetermined time in its inner reversing position between two wiping cycles.

Abstract: A windshield wiper assembly includes a helical compression spring arranged laterally staggered relative to the wiper shaft in such a way that the center line of the helical compression spring runs alongside the wiper shaft. This permits the wiper arm to be made very compact and low, so that it can be used in motor vehicle windshield wiper installations having a concealed parking position.

Abstract: A windshield wiper assembly is disclosed which includes a pivot pin between the side walls of the main yoke. A connecting element for a wiper arm is mounted on the yoke. The wiper arm projects from the back of the main yoke and is bent such that it laterally extends beside the wiper blade.
