Wiper arm for windshield wipers of automotive vehicles

Windshield cleaning system, especially for motor vehicles

A connection and two step method of manufacturing is disclosed for a drive unit for a wiper arm system which consists of a wiper shaft mounted in a bore through a crank arm. The wiper shaft is formed with a groove disposed within the thickness of the crank arm and material from one surface of the crank arm is displaced to form an annular recess which causes crank arm material adjacent the groove to be radially displaced into a groove formed in the wiper shaft to form an axial holding element. The radial distance R1 of the recess from the crank arm bore is substantially equal to the axial distance A1 of the groove below the one crank arm surface to facilitate the extruding process. Knurled areas on the shaft on either side of the groove are press fit into the crank arm bore as a first step in assembling the shaft to the crank arm, bringing a flange into abutment against the other surface of the crank arm.

A spare wiper element for a wiper blade and a method for the assembly of the spare wiper element. The spring bars are held in lateral grooves of a wiper rubber basic body and are secured by holding clamps lapping over the basic body of the wiper rubber during the assembly with the supporting yoke system.

Spare wiper element

This invention relates to a connecting member for a wiper blade and a wiper arm including a plastic structural member and a metallic locking spring. The structural member has a bearing bore as a receiver for a pivot pin. The locking spring is retained at a first end portion and intersects the bearing bore and acts upon the pivot pin by means of its center area. A second end portion of the spring forms a release key positioned behind the bearing bore. The release key of the locking spring is covered by a wing which is intergrally formed as part of the wall of the structural member by means of a film hinge.

In a wiper blade for a vehicular windshield wiper system, the main yoke is equipped with a spoiler constructed such that the overall height of the wiper blade is not enlarged and nevertheless the spoiler is prevented from touching the window pane to be cleaned. The spoiler is formed in such a way that the wiping pattern does not deteriorate at low or higher driving speeds.

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.

Windshield wiper system

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.

A windshield wiper system for motor vehicles includes an electric motor which drives at least one wiper during normal wiper operation, too and fro between two reversing positions within a wiping area. When the wiper system has been switched off by means of an operating switch, the wiper is moved to a concealed parking position outside the wiping area. Upon switching on of the wiper system and during normal operation the motor runs in one direction of rotation, but for moving the wipers into the parking position the motor runs in the other direction of rotation. A position switch is changed over by a switching member coupled with a rotating drive member of the electric motor. The position switch, after the operating switch has been switched off, releases a signal for reversing the polarity and in the parking position releases a signal for switching off the electric motor. So that the wiping cycle for entering the parking position begins in the first reversing position adjacent to the parking position and the wiper occupies the first reversing position in the dwell time interval of intermittent operation, the position switch is changed over independently of the direction of rotation of the electric motor and always in the same position of the drive member.

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.

Windshield wiper unit

A low overall height is provided in a wiper-arm assembly with a wiper arm which has a fastening part, a link part which is swivelably linked to the fastening part and two side walls and a back connecting the two side walls, and a contact pressure spring which is accommodated in the link part and acts on the link part and the fastening part, and also with a wiper blade linked to the wiper arm, which blade lies at least partly in line with the link part. The low height is achieved by making the clearance between the contact pressure spring and the one side wall of the link part greater than the width of the wiper blade in the area of the link part and by the wiper blade being swivelable into the link part alongside the contact pressure spring.

Windshield wiper-arm assembly

A windshield wiper yoke and a method for producing same is described. The wiper yoke is formed from a single strip of sheet metal which is bent to have a U-shaped cross-section. The web of the yoke includes a plurality of slots each of which extends in width to or beyond the imaginary bending lines. With slots provided in accordance with the invention, the wiper yoke exhibits relatively good aerodynamic behavior at high vehicle speeds.

In a windshield wiper assembly, the contact pressure of the wiper blades against the windshield is varied by displacing the wiper shaft in a direction along the axis of the shaft.
