Abstract

A vehicle restraint system is provided which comprises an airbag into which an inflator can assembly may be placed. The inventive airbag preferably comprises two body panels, attached by one substantially straight seam, and a separator panel which, upon folding and attaching of the two body panel sections of the airbag produces a looped pocket for holding of the above-mentioned inflator can assembly. Such an article allows for quick and complete inflation upon release of propellant and facilitates packing in a standard restraint system enclosure. The invention thus encompasses both the restraint system and the airbag itself.

Claims

1. A vehicle restraint system comprising

an airbag inflator can;

and

an airbag including a looped pocket;

wherein said airbag inflator can is disposed within said looped pocket of said airbag;

wherein said airbag comprises a single piece of fabric having a first body panel section and a second body panel section contacted together through a single fold of said single piece of fabric and attached together, and a third panel section extending between said first and second body panel sections;

wherein, upon said attachment of said first and second body panel sections to form a single structure, said third panel extends in a looped fashion below said single structure to form said looped pocket; and

wherein the minimum width of said airbag is at least the same as that of said looped pocket.

2. The vehicle restraint system of claim 1 wherein each of said first and second body panel sections is the mirror image of the other.

3. The airbag of claim 1 wherein each of said first and second body panel section is the mirror image of the other.

4. The vehicle restraint system of claim 1 wherein said third panel of said airbag is rectilinear in shape.

5. An airbag including a looped pocket for disposition of an airbag inflator wherein said airbag comprises

a single piece of fabric having a first body panel section and a second body panel section contacted together through a single fold of said single piece of fabric and attached together;

and

a third panel section extending between said first and second body panel sections;

wherein upon said attachment of said first and second body panel sections to form a single structure, said third panel extends in a looped fashion below said single structure to form said looped pocket; and

wherein the minimum width of said airbag is at least the same as that of said looped pocket.

6. The airbag of claim 5 wherein said third panel is rectilinear in shape.
