Abstract
An improved windshield wiper assembly for a motor vehicle which includes a connecting member connected to a wiper arm of the motor vehicle. A frame of the windshield wiper assembly is sealed by a rubber sheet disposed under the connecting member, and a bridge member is fixed between the connecting member and the rubber sheet. The bridge member includes a pair of flexible, elongated vanes which extend downwardly and at an angle from a front surface thereof, and a plurality of pairs of holes disposed on the top surface of the bridge member. The vanes direct the flow of air through the holes in the bridge member, thereby increasing air pressure on the wiper blade and improving the performance of the windshield wiper assembly.
