VEHICLE AIR SPOILER
ABSTRACT
A combination of a laterally extending bumper assembly and an air spoiler mounted on the front end of a vehicle. The vehicle bumper assembly comprises an ornamental face bar and a bumper reinforcement concealed therebehind. The air spoiler comprises an airfoil ex-tending laterally beneath the vehicle rearwardly of the bumper assembly. The airfoil is supported for swinging movement about a horizontal pivot axis located in rearward spaced parallel relationship to the bumper assembly.
The airfoil is swingable about the pivot axis from a retracted substantially concealed position behind the bumper assembly to a position in which it is substantially deployed below the level of the bumper assembly to restrict the flow of air beneath the vehicle.

Description
11~969~5 The present inventîon relates to a vehicle air spoile~.
U.S. patent 2,036,560 issued April 7, 1936 to W. T. Backus for "Land Vehicle Equipment" documents an early attempt to improve the streamlining of moving vehicles by reducing the airflow under the vehicle. The patentee pointed out that the undersurface of a vehicle "is the source of eve~ more loss of efficiency than resùlts from unimproved upper surfaces of the same vehicle2' for two reasons. "First, numerous projections on the bottoms of vehicles increase the amount of wind resistance; and, second, the air pressure which is built up underneath the moving ca~
in the restricted spac~ between the bottom surface of the vehicle and the ground increase the amount of drag or re-tardation from wind resistance." The patentee's solution was to provide an airfoil at the front of the vehicle that had a non-convex upper surface to direct air away from the I underside of the vehicle. Subsequently, it was determined that an airfoil or a spoiler mounted beneath the front end of the vehicle also would be advantageous. The ~anuaxy, 1970 issue of Motor Trend Magazine, at page 40, has a pic-ture of the front end of a vehicle having a fixed spoiler mounted beneath the streamlined nose of the vehicle. The caption accompanying the picture states, "Spoiler not only kills ront end lift, but lowers overall drag by limiting airflow under the car and also aids engine cooling."
Such fixed spoilers have been used on many racing cars and high powered sport model versions of passenger cars.
U.S. patent 3,618,998 issued Novem~er 9, 1971 to D. A. Swauger for "Wind Load Applicator and Stabilizer for Steerable Front Wheels of Rear-Engine Vehicles1' carried the concept of a front end stabilizer or spoiler mounted beneath ~0969~5 the vehicle a step further. The Swauger patent discloses an airfoil member pivotally mounted adjacent and relative to a flat pan bottom of a well known type of vehicle. A
spring-loaded means supports the airfoil member in a normally raised position, the spring-loaded means being yieldable, however, to permit increased downward inclination of the airfoil and therefore greater downward pressure of the tires of the vehicle upon the pavementO

109~i9~5 Figure 3 is a side elevation illustrating the spoiler in deployed condition.
Referring now to the drawing, Fig. 1 discloses the front end of a motor vehicle, generally designated 10, having a forwardly projecting bumper assembly 11. The bumper assembly 11 comprises an ornamental face bar 12 and a box section reinforcing member 13 concealed behind the face bar 12. Mounted rearwardly of the bumper assemb.ly 11 between the latter and the front wheel 14 of the vehicle is an air spoiler, generally designated 150 ~.
10~69~5 1 The air spoiler 15 comprises an airfoil 16 that
2 extends laterally beneath the vehicle rearwardly of the
3 bumper assembly. The airfoil 16 has at each end a wing
4 tip portion 17 that extends longitudinally of the vehicle.
S Each wing tip portion 17 lies beneath the adjacent wing 6 tip 18 of the vehicle bumper assembly. The rear extremity 7 of each wing tip portion 17 is journalled on a pivot shaft 8 19 supported on a brace beneath the bumper wing tip por-9 tion 18. It will be understood, however, that the airloil similarly could be mounted independently of the bumper 11 assembly. The pivot support, for example, could be carried 12 on suitable brace members supported on the vehicle front end 13 sheet metal structure. The pivot axis of the aixfoil thus 14 extends in a substantially horizontal direction laterally of the vehicle and, as best seen in Figs. 2 and 3, is located 16 forwardly contiguous of the vehicle wheel 14.
17 The front face 21 of the spoiler 15 is curved rom 1% top to bottom. When the spoiler is in a deployed position, 19 as shown in Fig. 3, the curvature of the front face when ZO viewed from the side is seen to extend downwardly and rear-21 wardly of the vehicle.
22 In Fig. 2, the spoiler 15 is shown in a retracted 23 position in which it is substantially concealed behind the 24 bumper assembly. As briefly mentioned, in Fig. 3 the spoiler 15 is shown in a deployed position in which it is 26 substantially below the level of the b~mper assembly 11 27 thereby being in a position to deflect the airstream flowing 28 benea~th the vehicle downwardly and to restrict substantially ~9 the flow of air beneath the vehicle.
S Each wing tip portion 17 lies beneath the adjacent wing 6 tip 18 of the vehicle bumper assembly. The rear extremity 7 of each wing tip portion 17 is journalled on a pivot shaft 8 19 supported on a brace beneath the bumper wing tip por-9 tion 18. It will be understood, however, that the airloil similarly could be mounted independently of the bumper 11 assembly. The pivot support, for example, could be carried 12 on suitable brace members supported on the vehicle front end 13 sheet metal structure. The pivot axis of the aixfoil thus 14 extends in a substantially horizontal direction laterally of the vehicle and, as best seen in Figs. 2 and 3, is located 16 forwardly contiguous of the vehicle wheel 14.
17 The front face 21 of the spoiler 15 is curved rom 1% top to bottom. When the spoiler is in a deployed position, 19 as shown in Fig. 3, the curvature of the front face when ZO viewed from the side is seen to extend downwardly and rear-21 wardly of the vehicle.
22 In Fig. 2, the spoiler 15 is shown in a retracted 23 position in which it is substantially concealed behind the 24 bumper assembly. As briefly mentioned, in Fig. 3 the spoiler 15 is shown in a deployed position in which it is 26 substantially below the level of the b~mper assembly 11 27 thereby being in a position to deflect the airstream flowing 28 benea~th the vehicle downwardly and to restrict substantially ~9 the flow of air beneath the vehicle.
-5-10"~905 1 In Figs. 2 and 3, the line 22 represents a plane 2 extending from the lower forward edge 23 of the bumper 3 downwardly and rearwardly in to tangential relationship 4 with the periphery of the front wheels 14 forwardly of the contact surface of each wheel with the ground. The area
6 below the plane is preferably maintained free of any de-
7 pending appendages that might encounter road obstacles.
"8 It will be noted in Fig. 2 that the airfoil 16 in retracted 9 or raised position lies above the plane designated by the line 22. In Fig. 3, the airfoil is shown projecting below 11 the line 22 in deployed position. This is permissible -12 since the airfoil normally would be deployed only when the 13 vehicle is being operated at high speed over relatively 14 smooth road surfaces. ~
The airfoil 16 is swingable about the ~ivot 19 16 when retracted to deployed position and vice-versa by a 17 power operated mechanism generally designated 23. The 18 power operated mechanism 23 preferably comprises an 19 electric motor 24 driving a lead or jack screw 25 carrying a travelling nut 26. The motor 24 is pivotally mounted on 21 a bracket 27 fixed to the upper rear face 28 of the bumper 22 reinforcement box section 13. The travelling nut 26 is 23 pivotally coupled to a bracket 29 fixed to the airfoil 16.
24 The power operated mechanism 23 preferably is le~--ed centrally of the bumper assembly 11 and the airfoil 16 26 an~ is concealed beneath the front grill of the vehicle.
.
~G9~)5 ~ j 1It is to be understood this invention is not 2 limited to the exact construction illustrated and aescribed 3 above but that various changes and modifications may be 4 made without departing from the spirit and scope of the invention.
