In order to improve on a known wiper blade with a wind-directing device, which is manufactured as an integral component of the main support in one piece with this main support, especially with regard to a still greater amplification of the down-force of the wiper blade against the windshield to be wiped, the effective area of the wind-directing device is enlarged as follows: the wind-directing device on its opposite ends has cantilevered, wing-like elongations which protrude beyond the main support in its longitudinal direction.

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.

A windshield wiper unit has a slide which is supported so as to be movable in a longitudinal direction in a housing which is driven to and fro, and a wiper arm which is fastened with a fastening part to an end section of the slide. A low overall height is achieved by the fastening part having a recess with which it is placed on the end section of the slide in the longitudinal direction of the slide and by the end section being jammed in the recess.

This invention describes a so-called reciprocating wiper system having a guide housing moving pendulum fashion and a wiper arm guided therein and radially retractable and extractable, wherein by various measures the volume of the guide housing is changed as compared to known embodiments and thus adapted to the space conditions in the engine compartment of a motor vehicle, wherein because of a change in the volume a lengthening of the wiper blade and thus an enlargement of the wiping area is made possible.

A gearing of a reciprocating wiper system has two toothed wheels meshing with each other of which one is firmly connected with a crank. The mesh of a given tooth of one toothed wheel in a given space width of the other toothed wheel corresponds to a particular position of the crank. To facilitate assembly and to reduce the risk of assembly errors, in a particular position of the crank one toothed wheel has only one tooth which may be axially pushed into one space width of the other toothed wheel such that the meshing of the tooth in the space width corresponds to the particular position of the crank.

A connection between a wiper arm and the bracket of a wiper blade that is easy to manipulate during wiper blade changes but nevertheless is a secure rotatable connection, for a wiper blade in which a connector is provided on the wiper arm or the wiper rod, is achieved as follows; the connector has a through-hole with inside thread; the through-hole is placed concentrically to a geometric axis running transversely; a screw serving as the hinge pin is screwed into the through-hole, and in this way a releasable frictional engagement between the screw and the connector is created. The screw is fitted on its opposite ends with cylindrical bearing segments which protrude laterally out of the through-hole of the connector and are mounted rotatably in the respective bearing holes in the side walls of he connecting segment of the wiper blade bracket.

This invention relates to a wiper arm with the possibility of adjusting its contact pressure, wherein the link may be brought into a stable tilted position. Upon tilting the point of application of the wiper arm pressure spring on this side of the fastening member is displaced in the direction of the articulated axle between wiper arm fastening member and wiper arm link in a manner that the perpendicular spacing between the line of application of the pressure spring and the articulated axle is diminished. This is why a small tilting angle can be realized.

In a reciprocating wiper system for motor vehicles a piston is linearly displaceably guided in a housing and mounted in a bearing which is seated in a receptacle of the housing. A scraper ring and a sealing ring intended to clean the piston are positioned in front of the bearing. The sealing ring and the scraper ring are jointly mounted in the housing with the bearing as a structural unit. In a preferred embodiment the sealing ring and the scraper ring are held on a universal ball joint being part of the bearing.
摘要:
The piston of a reciprocating wiper system on which a wiper arm is mounted is guided to be linearly displaceable in a capshaped bearing and has a slide which is longitudinally guided by two guide elements fixed to the housing. To achieve jam-free guidance on the guide elements without adjustment, the slide is guided with a capshaped bearing on one guide element in a closed manner. In contrast thereto there is a play between the slide and the second guide element in the plane defined by the guide elements.

A wiper squeegee is mounted in the holding claws of a support frame. The capability of the wiper squeegee to shift in the longitudinal direction is limited by a fixed first stop on a first end of the support frame and a second stop which can move between a holding position and a release position on a second end of the support frame. An end piece on which the second stop is mounted is fastened on the second end of the support frame so that the end piece can rotate around a geometric axis which runs at least approximately parallel to the longitudinal direction of the wiper squeegee. This end piece can be locked, at least in the holding position.
