Abstract
Abstract Method and device for producing a protective airflow curtain forward of the windshield of vehicles having substantially flat fronts, i.e., cabover trucks, vans, buses, etc., comprising a concave planar surface having at least one straight edge mounted with such edge adjacent the windshield, a relatively flat surface extending from the concave surface in a direction opposite the windshield, and a barrier between at least one of the surfaces and the vehicle body, thereby redirecting a wind stream impinging upon the surfaces into a curtain flow spaced from and largely parallel to the windshield with the barrier preventing substantial flow of disruptive air behind the surfaces.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
141 words
A wind deflector mounted on a substantially flat-fronted vehicle with a windshield portion being included in the front, the wind deflector comprising: a concave curved planar surface having at least one substantially straight edge positioned adjacent an edge of the windshield, a relatively flat surface of a curvature less than that of the concave surface extending from the concave surface in a direction away from the windshield, and a barrier surface extending from the edge of the substantially flat surface opposite the curved surface to a position in close proximity to the vehicle front, whereby an airstream impinging upon the relatively flat surface will be induced to flow toward the curved surface, the curved surface will direct the airflow in a direction more than 90* to the airstream direction and the barrier surface will diminish air movement behind the curved surface.
Claim 2
Dependent Claim
141 words
A wind deflector mounted on a substantially flat-fronted vehicle with a windshield portion being included in the front, the wind deflector comprising: a concave curved planar surface having at least one substantially straight edge positioned adjacent an edge of the windshield, a relatively flat surface of a curvature less than that of the concave surface extending from the concave surface in a direction away from the windshield, and a barrier surface extending from the edge of the substantially flat surface opposite the curved surface to a position in close proximity to the vehicle front, whereby an airstream impinging upon the relatively flat surface will be induced to flow toward the curved surface, the curved surface will direct the airflow in a direction more than 90* to the airstream direction and the barrier surface will diminish air movement behind the curved surface.
Claim 3
Dependent Claim
28 words
A wind deflector as described in claim 1 wherein the curved surface, the substantially flat surface and the barrier surface are formed of a unitary piece of material.
Claim 4
Dependent Claim
50 words
A wind deflector as described in claim 1 wherein the relatively flat surface is joined to the curved surface in a tangent relationship thereto and the barrier surface is attached to the opposite end of the relatively flat surface and angled therefrom in an opposite direction than the curved surface.
Claim 5
Dependent Claim
97 words
A wind deflector secured to the front of a vehicle having a substantially flat, vertical frontal area with a windshield forming a portion of the frontal area, the deflector being mounted to the frontal area adjacent the windshield with a curved, concave surface immediately adjacent the windshield, a relatively flat surface having a curvature less than that of the curved surface extending from the curved surface at the side of the curved surface opposite the windshield, and a barrier surface between at least one of the curved surfaces and relatively flat surface and the vehicle frontal area.
Claim 6
Dependent Claim
97 words
A wind deflector secured to the front of a vehicle having a substantially flat, vertical frontal area with a windshield forming a portion of the frontal area, the deflector being mounted to the frontal area adjacent the windshield with a curved, concave surface immediately adjacent the windshield, a relatively flat surface having a curvature less than that of the curved surface extending from the curved surface at the side of the curved surface opposite the windshield, and a barrier surface between at least one of the curved surfaces and relatively flat surface and the vehicle frontal area.
Claim 7
Dependent Claim
45 words
A wind deflector as described in claim 4 wherein the relatively flat surface is mounted with the portion thereof adjacent the curved surface closer to the vehicle frontal area than the portion of the relatively flat surface which is more remote from the curved surface.
Claim 8
Dependent Claim
31 words
A wind deflector as described in claim 5 wherein the barrier surface extends from the portion of the relatively flat surface remote from the curved surface to the vehicle frontal area.
