  • Patent number: 5033157
    Abstract: A windshield wiper arrangement for a curved windshield comprises a joint shaft to which the wiper blade is mounted, and a channel-shaped retainer in which the joint shaft is pivotally mounted. The axis of the joint shaft is parallel to the longitudinal axis of the wiper blade. A linkage is pivotally coupled to the retainer to drive the wiper blade across the curved surface of the windshield. In the first embodiment, the joint shaft and wiper blade are prevented from rotation by a universal joint that is coupled to a fixed bearing by a connecting link. An elastic control link maybe operatively positioned between the fixed bearing and the connecting link, or the connecting link itself maybe elastic. In the second embodiment a lever having a universal ball and socket joint prevents rotation of the joint shaft and wiper blade. In the second embodiment the ball and socket joint are coupled to the linkage by an extension that is guided for longitudinal movement either by the linkage or the ball and socket joint.
