Abstract: The wiping device for a windshield of a motor vehicle includes at least one wiper lever with an articulated wiper element which contacts the windshield and is driven in a reciprocating manner between two reversing positions by a drive unit. A particularly reliable and precise operation is obtained, when the wiper lever is provided with at least one sensor on the windshield detecting a predetermined operating position of the wiper lever. The wiping device has a control device, to which the sensor and the drive unit are in working connection so that the drive unit can operate the wiper lever according to signals from the sensor.

Abstract: A wiping device for windows of power vehicles comprises a wiping member, a drive providing a rotary movement, a swinging transmission connected with the drive and having link parts including one link part which has a drive shaft carrying the wiping member, and a hinge which connects the link parts with one another, the hinge having a hinge pin which is mounted on one of the link parts, while another of the link parts has a pin bearing in which the hinge pin is supported, and a unit for adjusting an effective link length and including a guiding path which extends eccentrically to an axis of the pin bearing and at least partially surrounds the latter, and a counter guide provided on the other link part which carries the pin bearing, the path being formed as a portion of an Archimedes spiral.

Abstract: A device for wiping a windshield of motor vehicles comprises a wiper blade which brushes over a wiping field located between two oscillating reversing positions and which is securely connected with a rocker shaft via a wiper arm, and which can be placed in a rest position which is located prior to the wiping field as seen in one oscillating direction. The wiper device has a drive comprising an electrical drive motor and a crank operatively connected with the drive motor and forming a part of a pendulum gear unit which transmit the rotating movement of the drive motor into an oscillating movement of the rocker shaft. The crank is additionally supported with a shaft in an eccentric bush rotatable between two positions relative to a device housing in such a way that the axis of rotation of the crank is movable between a pendulum operating position and an additional position effecting the wiper blade rest position.

Abstract: An oscillating wiper device for motor vehicle windshields comprising a wiper arm including an inner partial arm having guide means for supporting an outer partial arm for rotation about the longitudinal axis thereof and for longitudinal displacement relative to the inner partial arm, and a structure which enables rotation of the outer partial arm about the longitudinal axis thereof upon oscillating movement of a wiper blade.

Abstract: A wiper device for a windshield of a vehicle comprising a wiper arm, a drive for oscillating the wiper arm, and an elongate flexible torsion rigid member for transmitting an oscillating movement of the wiper arm into pivotal movement of the wiping blade about an axis spaced from the windshield and extending substantially parallel thereto, the elongate flexible torsion rigid member including a fixed end having a longitudinal axis extending to the pivot axis of a pivot shaft attached to the other end of the elongate flexible member and connected to the wiping blade, at an angle less than 180.degree., and extending to the axis of a wiper shaft at an angle less than 90.degree., the pivot axis of the pivot shaft being a continuation of the longitudinal axis of the other end of the elongate flexible member.

Abstract: A wiping device for panes of power vehicles comprises a swingingly movable wiper arm which includes a first wiper arm part holding a swinging shaft and a second wiper arm part provided with a wiping element arranged to abut against a pane, and a hinge connecting the wiper arm parts with one another and having an axis extending approximately in a swinging direction, a unit for turning the second wiper arm part away of the pane so that the wiping element located in a parking position is unloaded, the unit including an electric motor having a drive shaft, and a lifting element operatively connected with the drive shaft and arranged so that it cooperates with the wiping element and the upper arm which together form a wiper lever when the motor is activated.

Abstract: A windshield wiper device includes an oscillating wiper blade supported on a wiper arm which oscillates together with the wiper blade on the windshield to be wiped and is connected with a drive which imparts to the wiper arm a longitudinal displacement during the oscillating motion. The drive includes a gear, a stationary toothed segment meshed with the gear, and a crank mechanism having a crank and a driving rod connected to the crank. An intermediate drive is provided between a reciprocating element connected to the wiper arm and the driving rod of the drive to enlarge a path of the translatory movement of the driving rod.

Abstract: A wiping device for windows of power vehicles, comprises a swingably movable wiping lever, a swinging shaft having a swinging axis, a guiding piece connected with the swinging shaft, an elongated lifting element which is radially displaceable relative to the swinging axis, the lifting element having an end which faces away from the swinging axis, a wiper arm articulately connected with the side of the lifting element, a wiping blade arranged on the wiper arm, a spring element arranged to press the wiping blade against a pane to be wiped, so that the wiping blade is subjected via the wiper blade to a swinging movement and via the lifting element to a displacement movement which is superposed upon the swinging movement and extends transversely to the swinging movement, the lifting element being provided with a movable abutment shoulder which extends transverse to its direction of elongation, the guiding piece having a rear counter shoulder as considered in directional movement of the lifting element and coopera

Abstract: A device for wiping automobile windows is proposed. The wiper has a wiper arm that is guided displaceably, by means of a thrust crank mechanism, radially to the pendulum axis on a guide element driven for pendulum motion. On its free end, the wiper arm has a wiper blade placed against the window to be wiped. The guide element has a pendulum lever protruding beyond the pendulum axis, on which lever a gear wheel the axis of rotation of which is located parallel to the pendulum axis is rotatably supported. The gear wheel cooperates with a set of teeth connected to the chassis and concentric with the pendulum axis.

Abstract: A windshield wiper system for motor vehicles includes a wiper blade supported on an oscillating and reciprocating wiper arm driven by a plunger guided in a guide during its reciprocal movement and provided with a compensating hinge and supported by two parallel slides guided on two elongated guide rails parallel to the axis of elongation of the plunger. In order to compensate for alignment errors each slide is movable relative to the plunger about the axis of the compensating hinge.

Abstract: A wiper device for wiping panes of motor vehicles includes a wiper having an oscillating arm and a blade positioned against the pane, and a drive for, imparting the oscillating movement to the wiper. To synchronously influence the wiper in its oscillating movement a transmitting pulling rope drive is provided, which is connected to the oscillation drive and cooperates with the wiper arm. In dependence upon the angle included between the blade in its reverse position and the blade in its respective operative position the wiper blade can be adjusted to predetermined operational conditions.
