SELF-DEPLOYING CHIN SPOILER
FOR A VEHICLE
ABSTRACT
The combination of a laterally extending bumper mounted on the front end of a vehicle and a chin spoiler mounted beneath the bumper, the vehicle bumper having an ornamental face bar and a reinforcement member concealed therebehind. The chin spoiler comprises a support means fastened by conventional fastening means to the bumper re-inforcement and an airfoil. The airfoil is contoured along its leading edge to complement the frontal contour of the bumper face bar. A hinge means secures the airfoil along its rear edge to the support means rearwardly of the bumper rein-forcement. Biasing means interposed between the support means and the airfoil normally biases the latter towards the under-side of the bumper face bar in a concealed position beneath the vehicle. The hinge means provides a hinge axis extending laterally of the vehicle about which the airfoil is deployable.
The biasing means resists such deployment until the speed of the vehicle reaches a predetermined velocity at which the air pressure exerted upon the upper surface of the airfoil over-comes the biasing force of the biasing means causing the air-foil to pivot downwardly to present greater frontal area to the air stream trying to pass under the vehicle.

Description
109~38~3 The present invention relates to chin spoilers for vehicles.
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 even more loss of efficiency than results from unimproved upper surfaces of the same vehicle" 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 car in the restricted space between the bottom ~urface of the vehicle and the ground increase the amount of draft or retardation 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 underside of the vehicle.
Subsequently, it was determined that an airfoil or a spoiler mounted beneath the front end o~ the vehicle also would be advantageous. The January, 1~70 issue of Motor Trend Magazine, at page 40, has a picture of the front end of a vehicle having a fixed spoiler mounted benea-th the streamlined nose of the vehicle. The caption accompan-ying the picture states, "Spoiler not only kills front 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 3,618,398 issued November 9, 1971 to D.
A. Swauger ~or "Wind Load Applicat~or and Stabilizer for ~ 2 --'t,.`~
7~851 Steerable Front Wheels of Rear-Engine Vehicles" carried the concept of a front end stabilizer or spoiler mounted beneath 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 pavement.
The present invention relates to a laterally exten-ding vehicle bumper mounted on the front end of a vehicle and a sel~-deploying chin spoiler mounted beneath the bumper, the vehicle bumper having an ornamental face bar and a reinforcement member concealed therebehind. The chin spoiler comprises a support means attached to the bumper reinforcing member. An airfoil is contoured along its leading edge to complement the frontal contour of the bumper face bar and is secured along its rear edge to the suppoxt means rearwardly of the bumper reinforcing member by a hinge means. Biasing means interposed between the support means and the airfoil normally bias the latter toward the underside of the bumper face bar in a concealed position beneath the vehicle. The hinye means provides a hinge axis extending laterally of the vehicle with the airfoil being deployable about this hinge axis~ The biasing means resists such deployment until the speed of -the vehicle reaches a predetermined velocity at which the air pressure exerted upon the upper surface of the airfoil overcomes the biasing force of the biasing means thereby , 1~ ... '~ .

causing the airfoil to pivot downwardly to present greater frontal area to the airstream trying to pass under the vehicle.
In the structure o this invention, therefore, a self-deployable spoiler is coordinated with the bumper structure of a vehicle. The spoiler is inconspicuous at no or low speed, but is adapted to self-deploy when the vehicle reaches critical speeds where such devices become effective or beneficial. Such a spoiler, because of its forward location, is known as a "chin spoiler."
The invention is described further, by way of illustration, with reference to the accompanying drawings, in which Figure 1 is a ragmentary perspective view of the front end of a vehicle having the bumper-spoiler combina-tion em~odying the present invention, the spoiler being shown deployed in at least three positions;

The airfoil 17 also may be considered a leaf. Prefer-ably, the support leaf 16 and the airfoil leaf 17 are molded of , 7~
1 suitable plastic and are integrally connected to each other 2 along their rear edge portions 19 and 21 by a living hinge
3 22 (see Fig. 4). It should be understood, however, that
4 the leaves 16 and 17 may be molded as separate pieces and connected by an equivalent mechanical hinge device such as the 6 well known piano hinge. The longitudinal axis of the air-7 foil 17 substantially parallels the longitudinal axis of the 8 support leaf 16 and thereby the longitudinal axis of the 9 bumper relnforcement 14.
The bumper reinorcement 14 has a vertical rear face 11 23. The support leaf 16 has an elongated right angle brace 12 24 mounted on its upper surface, the brace 24 having a 13 vertical upstanding flange 25 positioned against the vertical 14 rear face 23 of the bumper reinforcement 14. The primary function of the brace 24 is to reinforce the support leaf 16 16 against bending stresses that would tend to bend the leaf 17 around the rear lower edge 27 of the bumper reinforcement 14.
18 The airfoil 17 is normally biased upwardly toward 19 the support leaf 16 by biasing devices 28. At least two biasing devices 28 are utillzed, the de~ices being located 21: near the outboard ends of the airfoil 17. As best seen in 22 Figs. 5 and 6, a biasing device 28 comprises a bracket 29 23 secured to the support leaf 16, the bracket having a depending 24 flange 31 projecting downwardly through a cut-away portion 32 ~25 in the suppor~leaf 16 and airfoil 17. The flange 31 receives 26 a shaft or bolt 33 of a cylindrical elastomeric torsion 27 element 34, the latter being non-rotatably held relative tG
28 the bracket 29. A torsion element engageable member 35 is 3L~19~3~
1 mounted on the underside of the airfoil. As best seen in 2 Figs. 5 and 6, the member 35 has a paddle portion 36 bonded 3 or otherwise mechanically fastened to the airfoil and an 4 arcuate portion 37 bonded to the perimeter 38 of the torsion element 35.
6 The airfoil leading edge 18 has a downwardly extend-7 ing lip 39 adapted to catch a portion of the airstream passing 8 underneath the vehicle, see Fig. 3. The torsion elements 34 g resist downward pivoting movement of the airfoil until the forward speed of the vehicle approximates 40 miles per hour 11 (64.37 kilometers per hour). At this speed, the deployed 12 condition shown in Fig. 2 is obtained. With reference to 13 Fig. 1, the deployed airfoil is shown in solid outline in 14 approximately the Fig. 2 position, but it may ba in any posi-tion such as either of the two dot and dash outline positions 16 shown~or any other intermediate position between non-deploymer.t 17 and maximum deployment permitted by the torsion elements 18 depending on vehicle speed above 4b mph (64.37 kmph).
19 ~ The integration of the chin spoiler 15 with the bumper 12 is advanta~eous for several reasons. The underside of 21 the bumper structure is relatively uncluttered and provides a 22 convenient place to mount the chin spoiler assembly. The 23 alignment of the chin spoi}er beneath the bumper for conceal-24 ment from above is faeilitated. Also, since the bumpers of ~25 current model vehicles are mounted on energy or shock absorbing 26 devices that permit rearward movement of the bumper under 27 impact, the chin spoiler assembly is protected since it moves -28 with the~bumper unit.
_ 7 _ ~7388 1 It is to be understood this invention is not limited 2 to the exact cons~tructions illustrated and described a~ove, 3 but that various changes and modifications may be made without 4 departing ~rom the spirit and scope of the invention.
