Motor vehicle windshield wiper apparatus with storm pattern

摘要

Windshield wiper apparatus for a motor vehicle includes a first wiper pivoted below the driver side of the windshield and capable of wiping an arc between the bottom center and the driver side end thereof, a second wiper pivoted to the passenger side of the pivot of the first and capable of wiping an arc between the bottoms of the driver and passenger sides thereof, said arcs having a substantial portion of overlap on the driver side, first and second motors effective to drive the first and second wipers at substantially similar speeds and control apparatus having a mode of operation in which it is effective to drive the wipers in tandem from the bottom of the windshield to the end of the arc of the first wiper at the driver end of the windshield, hold the first wiper in that position while driving the second wiper to the bottom of the driver side and back and then drive both wipers in tandem back to the starting point. Thus the overlapping portion of the arcs receives additional wipes and is positively cleared on each wipe.
