Abstract
A laterally movable wiper arm assembly cleans curved interior surfaces of automobile and truck windshields. The wiper blade is movable on two curved tracks; one at the top of the windshield and one at the bottom of the windshield, with a vertically oriented telescoping wiper blade movable laterally therebetween. The telescoping arm support permits the vertical blade to tilt into the corners at the bottom of the windshield, to cover a larger proportion of the area, since the bottom of a windshield is longer than the top. The blade or wiping pad is supported with a resilient foam layer attached to a flexible substrate, which is adjustably attached to a rigid support arm following the windshield contour.
