ABSTRACT:
A windshield wiper blade made of a synthetic elastomeric material includes an elongated body having a longitudinal axis, a longitudinally extending central squeegee rib and a longitudinally extending scraping rib immediately adjacent to and on each side of the squeegee rib. All three of the ribs are integral with the body and project outwardly in the same direction from the body. The squeegee rib has a greater radial length than the scraping rib. Each of the scraping ribs has one 90 degree scraping edge and the squeegee rib has a pair of 90 degree squeegee edges. The one squeegee edge and the one scraping edge on the side facing the direction of movement of the blade engage the windshield. The scraping rib on the other side of the squeegee rib is out of contact with the windshield but engages the squeegee rib to effect lateral stiffness of the squeegee rib. A mounting rib is integral with the body and projects outwardly therefrom at a location essentially diametrically opposite the squeegee rib. The mounting rib provides a longitudinally extending hinge about which the body can swing in either direction.
