1. A windshield wiper assembly for a motor vehicle, which comprises:
- a wiper arm attached to a body of said motor vehicle;
a windshield wiper frame comprising a bridge member attached to said wiper arm, said bridge member having a top surface, a front surface and a rear surface, said bridge member supporting a bendable lip which contacts a windshield glass of said motor vehicle, said bendable lip having two sides;
means for directing air flow to press said bridge member downwardly, said means for directing comprises at least one horizontally elongated vane extending downwardly and at a slant from said front surface of the bridge member; and
at least one horizontally elongated vane extending upwardly and at a slant from said top surface of the bridge member, the at least one upwardly extending vane being smoothly joined to the top surface of the bridge member, a plurality of holes being provided on the top of the bridge member, whereby the air flow over said bridge member is directed by said vane through said holes such that a balanced pressure is maintained on the two sides of said bendable lip and a downward force is exerted on the bridge member, a constant upward slant is provided from the top surface of the bridge member to the at least one upwardly extending vane such that an area between the plurality of holes on the top surface of the bridge member and the at least one upwardly extending vane is without any depressions, the area between the plurality of holes on the top surface of the bridge member and the at least one upwardly extending vane extending horizontally for a predetermined distance such that a gradual slope to the at least one upwardly extending vane is provided.
