  • Patent number: 4641390
    Abstract: An improved windshield wiper system having an articulated wiper arm assembly, in the form of a wiper arm and a drag arm, which incorporates a three-link parallelogram arrangement wherein a greater blade wiping area is attained at selected portions of the windshield. A portion of the outer end of the wiper arm is pivotally connected to one end of each of a pair of parallel outer and inner links. The other ends of the pair of links are pivotally connected to a blade support link such that the blade is maintained parallel with the wiper arm. The free end of the drag arm is pivotally connected to an intermediate point on the inner link. Consequently, the blade is positioned at a radially minimum location when the blade is at its rest or park position and a radially maximum location upon the blade traversing a predetermined arc.
