ABSTRACT:
A windshield wiper system which when operating will define a non-circular wiping pattern of a windshield wiper. The system includes a motor spindle and at least one windshield wiper arm interconnecting the motor spindle and the wiper arm for providing sliding movement in a radial direction. There includes a control component for controlling the sliding movements of the arm. The control component includes a drive spindle and arm mounted on the drive spindle which is adapted to be rotated. A coupling member interconnects a plurality of pivot members which are spaced eccentrically. An engaging member translates the wiper and wiper arm from an entirely semicircular path equidistant from the motor spindle to a non-circular path with respect to the motor spindle in at least two portions of the wiping pattern.
