Abstract

A wiper apparatus employed in a windshield wiper system for supporting a pair of wiper elements via a wiper drive arm pivotably mounted proximate a vehicle windshield. The wiper apparatus comprises a drive arm attachment member adapted to be coupled with the wiper drive arm. In one embodiment, a pivot arm is pivotably secured to the drive arm attachment member about a pivot axis which intersects the windshield. The pivot arm is configured to carry the pair of wiper elements such that each of the wiper elements moves over a corresponding first arcuate path when the drive arm is rotated in a first direction and moves over a corresponding second arcuate path when the drive arm is rotated in an opposite direction. Each of the first and second paths of a first wiper element is different from each of the first and second paths of a second wiper element. In one embodiment, each of the wiper elements moves between a corresponding upper position when the drive arm is rotated in the first direction, and a corresponding lower position when the drive arm is rotated in the opposite direction. In another embodiment, each of the wiper elements moves between a corresponding first angular position when the drive arm is rotated in the first direction, and a corresponding second angular position when the drive arm is rotated in the opposite direction.
