DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Firstly, referring to FIG. 1 which is a perspective view of the air bag cover 12, bracket member 14 and the lock 16 which comprises the air bag anti-theft device 10.

The air bag cover 12 consists of the front portion 12B, first side portion 12C, second side portion 12A and stabilizing member 12D. The first side portion 12C and second side portion 12A are substantially parallel to each other and each extend backward from one of the side edges of the front portion 12B. This configuration allows the air bag cover 12 to engage and enclose the center portion of the steering wheel 18A (shown in FIG. 2) containing the air bag device. The air bag cover 12 enclosing the center portion of the steering wheel 18A will deny access to this part of the vehicle, which will prevent the theft of the air bag device.

The second side portion 12A must be of a length that will allow the second side portion 12A to extend backward enclosing the ignition switch on the steering column 20 of the vehicle (shown in FIG. 5). The second side portion 12A enclosing the ignition switch will prevent tampering, which is a further feature of the air bag anti-theft device 10.

Contained within the rear-upper portion of both the first side portion 12C and second side portion 12A is a bracket slot 12F. The bracket slot 12F on the first side portion 12C extends into the stabilizing member 12D as shown. Both bracket slots 12F allow the bracket member 14 to be attached to the air bag cover 12. Extending outward from both the upper edges of both the first side portion 12C and second side portion 12A is a side flange 12G. Both side flanges 12G increase the surface area of the upper edge of both the first side portion 12C and second side portion 12A, which makes them stronger and harder to cut.

Attached to the rear edge of the first side portion 12C is the stabilizing member 12D. The stabilizing member 12D engages the left side of the steering column 20 (shown in FIG. 2) which functions to stabilize the air bag cover 12 on the steering wheel 18 (shown in FIG. 2). The stabilizing member 12D when engaged to the steering column 20 will further prevent the rotation of the steering column 18 which is another feature of the air bag anti-theft device 10.

The stabilizing member 12D consists of the front flange 12DA which extends outward approximately at a right angle from the rear edge of the first side portion 12C and the side flange 12DB which extends backward approximately at a right angle from the first edge of the front flange 12DA. The stabilizing member 12D further includes a top flange 12DC which is attached squarely to both the top edge of the front flange 12DA and side flange 12DB, and a bottom flange 12DD which is also squarely attached to the both the bottom edge of the front flange 12DA and side flange 12DB. The above discussed flanges are attached to each other at right angles so that the stabilizing member 12D will engage the three surfaces of the steering column 20 squarely.

Contained within the side flange 12DB is the first notch 12DE and second notch 12DF. The first notch 12DE is positioned within the upper portion of the rear edge of the side flange 12DB to allow an accessory lever such as a tilt wheel lever (not shown) to pass through. The second notch 12DF is positioned within the middle portion of the rear edge of the side flange 12DB to allow the signal lever 22 (shown in FIG. 2) to pass through.

The air bag cover has five embossments 12E stamped into its surface. Two embossments are contained within the front portion 12B (shown in FIG. 3), and one embossment is contained within each of the first side portion 12C, second side portion 12A and side flange 12DB. The embossments strengthen the air bag cover 12, which allows it to be fabricated from a thinner material. Also, the air bag cover 12 has protective trim 13 on its upper and lower edges. The protective trim 13 protects the steering wheel 18 of the vehicle from damage.

The bracket member 14 which is adapted to be attached to the air bag cover 12 functions to secure the air bag cover 12 to the steering wheel 18. The bracket member 14 consists of the first leg 14A, nose portion 14B and the second leg 14C. The first leg 14A and second leg 14C are substantially parallel to each other and are connected to each other by the nose portion 14B. The nose portion 14B is shown extending downward from the first leg 14A and second leg 14C.

The nose portion 14B provides added lateral strength to the bracket member 14. Because of the nose portion 14B configuration, it requires a greater force to pry the first leg 14A and second leg 14C apart, than if both legs were connected to each other by just a straight portion. Contained within the first distal end of both the first leg 14A and second leg 14C are the bracket orifices 14D. Both bracket orifices 14D are substantially aligned to each other to allow a locking means to pass through them.

Both the air bag cover 12 and bracket member 14 can be fabricated from various types of rigid metals or metal alloys. Although, preferably the air bag cover 12 and bracket member 14 should be fabricated from a low carbon cold rolled steel. The air bag cover 12 preferably should be fabricated from a low carbon cold rolled steel having a thickness of 3/32 of an inch, while the bracket member should be fabricated from the same material having a thickness of 3/16 of an inch. After the air bag cover 12 and bracket member 14 are fabricated from the low carbon rolled steel, they will be hardened by a case hardening process.

The lock 16 secures the bracket member 14 to the air bag cover and is an embodiment of the locking means. The lock 16 has two lock channels 16A and two lock cylinders 16B. The lock channels 16A are configured to receive the ends of the first leg 14A and second leg 14C of the bracket member 14. The lock cylinders 16B are capable of moving inward within the locking channels 16A passing through the bracket orifices 14D, thereby securing the ends of the first leg 14A and second leg 14C therein.

Referring to FIG. 2 which is a left side perspective view of the steering wheel 18 containing the air bag device. The center portion of the steering wheel 18A contains the air bag device. The steering wall 18 is shown rotated approximately forty-five degrees from the straight position so that the center portion of the steering wheel 18A is vertical lengthwise. The air bag anti-theft device 10 can only be installed when the steering wheel 18 is in this position.

Referring to FIG. 3 which is a left perspective view of the air bag anti-theft device 10 secured to the steering wheel 18. The air bag cover 12 is engaging and enclosing the center portion of the steering wheel 18A. The stabilizing member 12D squarely engages the left side of the steering column 20. Because the stabilizing member 12D squarely engages the steering column 20, it cannot be forced to slip and allow the steering wheel 18 to rotate. The signal lever 22 is passing through the second notch 12DF.

Referring to FIG. 4 which is a right perspective view of the air bag anti-theft device 10 secured to the steering wheel 18. The second side portion 12A extends backward enclosing the ignition switch on the steering column 20. The bracket member 14 is attached to the air bag cover 2, by placing the second leg 14C within the two bracket slots 12F as shown. Both ends of the first leg 14A and second leg 14B are in a position to be secured within the lock 16. The nose portion 14B is of a length to extend downward over the second side portion 12A, which acts as a barrier to prevent tools such as bolt cutters from trying to cut or damage the second side portion 12A. The nose portion 14B is further configured to allow the transmission lever 24 to pass through it.

Referring to FIG. 5 which is a top perspective view of the air bag anti-theft device 10 secured to the steering wheel 18. From this view both side flanges 12G are shown extending outward from the top edges of both the first side portion 12C and second side portion 12A. The first leg 14A and second leg 14B are secured within the lock 16, which will secure the bracket member 14 to the air bag cover 12.

When installing the air bag anti-theft device 10, the steering wheel 18 of the vehicle must be rotated approximately 45 degrees from the straight position as shown in FIG. 2. Then the air bag cover is placed over the center portion of the steering wheel 18A, thereby engaging the air bag cover 12 thereon. The second leg 14C is then slid into both bracket slots 12F attaching the bracket member 14 to the air bag cover 12 as shown in FIG. 4. Then the lock 16 is placed within both bracket orifices 14D, thereby securing the air bag cover 12 to the steering wheel 18.

It will be understood that each of the elements described above, or two or more together, may also find a useful application in other types of constructions differing from the type described above.

While the invention has been illustrated and described as embodied in an air bag anti-theft device, it is not intended to be limited to the details shown, since it will be understood that various omissions, modifications, substitutions and changes in the forms and details of the device illustrated and in its operation can be made by those skilled in the art without departing in any way from the spirit of the present invention.

Without further analysis, the foregoing will so fully reveal the gist of the present invention that others can, by applying current knowledge, readily adapt it for various applications without omitting features that, from the standpoint of prior art, fairly constitute essential characteristics of the generic or specific aspects of this invention.

What is claimed as new and desired to be protected by Letters Patent is set forth in the appended claims.
