Abstract

A method and apparatus for inhibiting full deployment of a vehicle air bag during a rescue operation utilizing a cover which can be tightly fitted and fastened about a vehicle steering wheel so that an activated air bag is confined within the cover and substantially inhibited from deploying into the driver area of the vehicle.

Claims

1. Apparatus for inhibiting full deployment of an air bag in a vehicle, the air bag being deployed from a hub region of a steering wheel of the vehicle, the apparatus comprising:

a generally round sheet of flexible material having a diameter greater than a diameter of a vehicle steering wheel, said sheet comprising at least a pair of reinforcing strips criss-crossing said sheet; and

means connected to a periphery of said sheet for forming said sheet into a generally bag-like configuration having an opening smaller than the diameter of the steering wheel, whereby when said sheet is positioned on the steering wheel the periphery can be formed about an underside of the steering wheel for preventing full deployment of an air bag contained within the steering wheel.

2. The apparatus of claim 1 wherein said forming means comprises a drawstring attached to the periphery of said sheet.

3. The apparatus of claim 2 wherein said sheet includes a hem formed about the periphery of said sheet and having an opening for passage of said drawstring.

4. The apparatus of claim 1 wherein each end of each of said pair of strips terminates in a closed loop, said forming means comprising a drawstring passing through each of said loops.

5. The apparatus of claim 4 wherein said drawstring passes twice around the periphery of said sheet through said loops.

6. The apparatus of claim 4 and including a second pair of strips criss-crossing said sheet, each strip of each of said pairs of strips being angularly displaced with respect to each other.

7. Apparatus for inhibiting full deployment of an air bag in a vehicle, the air bag being deployed from a hub region of a steering wheel of the vehicle, the apparatus comprising:

a plurality of angularly spaced strips of generally uniform length and width, each of said strips being attached to each other at a generally central area and each of said strips terminating in a closed loop at each end thereof, the length of said strips including said loops being greater than the diameter of a steering wheel;

a drawstring passing at least once through each of said loops for drawing said ends of said strips into a generally circular form having a diameter less than a diameter of a vehicle steering wheel, whereby when said strips are positioned on the steering wheel, the ends of said strips can be drawn about an underside of the steering wheel for inhibiting full deployment of an air bag contained within the steering wheel; and

a generally circular sheet of flexible material sewn onto said strips, said sheet having a diameter approximately equal to the diameter of the steering wheel.

8. The apparatus of claim 7 wherein said plurality of strips comprising four generally uniformly spaced strips.
