Abstract
Abstract A device for stabilizing vehicles, particularly racing cars, and a method of stabilization utilizing same which comprises a flat movable pressure plate which is hinged at adjacent the front of a vehicle and can be controllably moved upward or downward in accordance with the air pressure exerted thereon. A pivotal pressure plate is connected to the rear of the flat pressure plate and can move in accordance wherewith to maintain air pressure on the flat pressure plate. Movable side fences are additionally provided to confine air onto the top surface of the flat pressure plate and act as four rudder stabilizers at all times. A similar flat movable pressure plate arrangement with a second pivotal pressure plate and side fences is provided at the rear of the car behind the driver and the top rear surface of the vehicle. Air deflectors, particularly at the rear of the car, are also provided.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
195 words
A chassis construction for a racing car to improve stability, the car having front Wheels and rear wheels, said chassis construction comprising: a front chassis portion having a generally horizontal front upper surface and means mounted thereon defining a front pressure surface essentially within said front chassis portion and disposed generally over the front wheels of the car, said front pressure surface being generally horizontal and in general alignment with said chassis front upper surface, but being inclined upwardly toward the rear of the car, said front pressure surface being movable from said inclined position to a lower more horizontal position as the speed of the car increases, and a rear chassis portion having a generally horizontal rear upper surface and means mounted thereon defining a rear pressure surface essentially within said rear chassis portion and disposed generally over the rear wheels of the car, said rear pressure surface being generally horizontal and in general alignment with said chassis rear upper surface, but being inclined upwardly toward the rear of the car, said rear pressure surface being movable from said inclined position to a lower more horizontal position as the speed of the car increases.
Claim 2
Dependent Claim
195 words
A chassis construction for a racing car to improve stability, the car having front Wheels and rear wheels, said chassis construction comprising: a front chassis portion having a generally horizontal front upper surface and means mounted thereon defining a front pressure surface essentially within said front chassis portion and disposed generally over the front wheels of the car, said front pressure surface being generally horizontal and in general alignment with said chassis front upper surface, but being inclined upwardly toward the rear of the car, said front pressure surface being movable from said inclined position to a lower more horizontal position as the speed of the car increases, and a rear chassis portion having a generally horizontal rear upper surface and means mounted thereon defining a rear pressure surface essentially within said rear chassis portion and disposed generally over the rear wheels of the car, said rear pressure surface being generally horizontal and in general alignment with said chassis rear upper surface, but being inclined upwardly toward the rear of the car, said rear pressure surface being movable from said inclined position to a lower more horizontal position as the speed of the car increases.
Claim 3
Dependent Claim
19 words

Claim 7
Dependent Claim
27 words
The chassis construction of claim 5 including means biasing said flat plates and said second pivotal plate members upwardly to their respective upwardly inclined and upright positions.
Claim 8
Dependent Claim
25 words
The chassis construction of claim 1 wherein each of said pressure surfaces extend substantially from one side of the associated chassis portion to the other.
Claim 9
Dependent Claim
21 words
The chassis construction of claim 7 wherein said pressure surfaces extend over a major portion of the length of the car.
Claim 10
Dependent Claim
16 words
