Abstract:
1. A system for wiping a windshield of a vehicle in a rectangular field, including a wiper arm assembly, a wiper blade assembly operationally attached to said wiper arm assembly, and means for rotating and translating said wiper arm assembly to cause said wiper blade assembly to track in a linear path across said windshield, wherein said means for rotating and translating comprises: a) a mounting plate; b) a gear train including a first gear disposable adjacent said windshield, a second gear meshed with said first gear, and a third gear meshed with said second gear, said first, second, and third gears having first, second, and third axes, respectively, included in a straight line including a virtual pivot point, said first gear being non-rotationally attached to said mounting plate; c) a first non-linear track formed in said mounting plate; d) a motor having a stator and a rotor, said stator being slidable in said first track, and said rotor being supportive of said second gear; and e) a wiper arm fixedly attached at an inner end thereof to said third gear, wherein rotation of said second gear by said motor causes an outer end of said wiper arm to be drawn in a linear path across said windshield.
