A windshield wiper assembly including a one-piece plastic shaft and crank coupling the drive unit to the driven assembly.

Windshield wiper assembly

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.

Windshield wiper installation

A control circuit for a windshield wiper circuit provides for a depressed parking position by including a timing element which delays turn off of the motor for a time interval after the wiper reaches a position adjacent the parking position area.

Windshield wiper control circuit

Windshield wiper assemblies include apparatus to compensate for lifting forces exerted on a wiper arm and blade when a vehicle travels at high speeds. The wiper assemblies include a wiper arm spring connected to a wiper rod which carries the wiper blade. One end of the spring is connected to a pin mounted on a lever. The lever is pivotally movable so that the spring force on the wiper rod may be increased to compensate for lifting forces.

A wiper arm includes a wiper rod which is directly formed from wire rod.

Wiper arm

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.

Windshield wiper

A windshield wiper assembly is described wherein a separate pivot pin between the wiper arm and the supporting yoke is eliminated. The arm includes a generally 'U'-shaped wire end which is lockable into a recess on the back of the main yoke. The end of the 'U' serves as a pivot pin.
