Abstract
The present invention is an improved windshield wiper assembly. The assembly includes a wiper blade which undergoes oscillatory rotary motion and is swept back and forth between two extreme locations across a windshield to remove rain and other precipitation from the windshield. A brushless DC motor has its output shaft connected to the wiper assembly. The foregoing results in rotary oscillation of the blade and permits the elimination of the four-bar mechanism which is typical of prior art wiper assemblies. The rotary motion of the blade in either direction is decelerated when the blade reaches a preselected position between two extreme locations.
