Abstract
A single wiper mounted to a conventionally located, non-center wiper post is adapted to wipe a generally rectangular windshield. A primary arm and wiper blade are long enough to cover a main wipe pattern that covers most of the driver side of the windshield. A secondary arm and blade pivoted to the tip of the primary arm are continously pivoted by a drag link over a supplemental wipe pattern that covers the residual area on the passenger side. The width of the supplemental pattern remains relatively great until the secondary blade comes close to the windshield upper edge, where it is retracted to avoid collision.
