Abstract
Abstract An improved vented tailgate for use on a pickup truck or similar vehicle having a cargo area with front and side walls and a rear opening. The tailgate is provided with opposite end members which support transversely extending louver members defining downwardly and rearwardly inclined air passageways which permit the passage of air through the tailgate. The air passageways reduce air drag resulting in a substantial increase in fuel efficiency of the vehicle and also serve to deflect dirt and exhaust away from the vehicle. The louvers are formed by hollow tube members to provide a tailgate which is structurally strong to support loads in the open position. The tailgate may be provided as original equipment or be retrofit to the existing latch and hinge mechanisms of the conventional pickup truck. The orientation of the passageways also permit limited rearward vision through the tailgate from the cab of the truck.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
147 words
A tailgate pivotally mountable in the access opening of the cargo area betwen the side walls of a pickup truck bed having a floor, said tailgate comprising: (a) a frame having a plurality of spacedapart louver members, said louver members each having a front side and rear side and at least one louver having a first surface inclined rearwardly and downwardly between said sides which together with a similarly oriented second surface on the next adjacent louver member define an air passageway for directing airflow downwardly toward the roadway surface; and (b) hinge means for securing said frame to the bed whereby the frame is moveable relative to the access opening between a closed vertical position between the truck bed side walls and an open position generally co-planar with the truck bed floor with said front side of said louvers defining a generally planar load bearing surface.
Claim 2
Dependent Claim
147 words
A tailgate pivotally mountable in the access opening of the cargo area betwen the side walls of a pickup truck bed having a floor, said tailgate comprising: (a) a frame having a plurality of spacedapart louver members, said louver members each having a front side and rear side and at least one louver having a first surface inclined rearwardly and downwardly between said sides which together with a similarly oriented second surface on the next adjacent louver member define an air passageway for directing airflow downwardly toward the roadway surface; and (b) hinge means for securing said frame to the bed whereby the frame is moveable relative to the access opening between a closed vertical position between the truck bed side walls and an open position generally co-planar with the truck bed floor with said front side of said louvers defining a generally planar load bearing surface.
Claim 3
Dependent Claim
32 words
The tailgate of claim 1 wherein said frame is generally rectangular having a top, bottom and side edges with said top edge defining a recess therein to accomodate a fifth wheel tongue.
Claim 4
Dependent Claim

Claim 8
Dependent Claim
47 words
The tailgate of claim 1 wherein said lowest point on the said first surface of said one louver member is substantially horizontally aligned with the highest point on the second surface of the next subjacent louver member when the tailgate is in a closed generally vertical position.
Claim 9
Dependent Claim
31 words
The tailgate of claim 1 wherein said first and second surfaces are rearwardly inclined at approximately 45° with respect to the horizontal when said tailgate is in a vertical closed position.
Claim 10
Dependent Claim
36 words
The tailgate of claim 1 wherein at least a part of the rear side of said one louver is substantially horizontally aligned with at least a part of the front side of the next adjacent louver.
