Abstract

The present invention relates to a vehicle restraint system 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 mouth (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

a single-chambered airbag including a pocket;

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

wherein said airbag comprises a single sheet of fabric having

a) a first body panel section and a second body panel section contacted together through a single fold of said single sheet of fabric and attached together by at least one seam, wherein any and all such seams attaching said first and second body panel sections are substantially straight; and

(b) a separator panel section which, upon contacting and attaching Qf said two body panel sections produces said pocket.

2. The vehicle restraint system of claim 1 wherein

each of said first and second body panel section is the mirror image of the other;

wherein said separator panel section is rectilinear in shape and connects said first and second body panel sections; and

wherein upon attachment of said first and second body panel sections along their corresponding edges by a single seam to form a seamed structure said rectilinear separator panel section extends below said seamed structure to form said pocket.

3. A single-chambered airbag including a pocket;

wherein said airbag comprises a single sheet of fabric having

(a) a first body panel section and a second body panel section contacted together through a single fold of said single sheet of fabric and attached together by at least one seam, wherein any and all such seams attaching said first and second body panel sections are substantially straight; and

(b) a separator panel which, upon folding and attaching of said two body panel sections produces said pocket.

4. The airbag of claim 3 wherein

each of said first and second body panel section is the mirror image of the other;

wherein said separator panel section is rectilinear in shape and connects said first and second body panel sections; and

wherein upon attachment of said first and second body panel sections along their corresponding edges by a single seam to form a seamed structure said rectilinear separator panel section extends below said seamed structure to form said pocket.

5. A single-chambered airbag comprising an integrated pocket for reception of an inflator can, wherein said airbag is comprised of a single piece of fabric having multiple fabric panel sections, wherein said multiple panel sections are contacted together through a single fold of said single piece of fabric, and wherein all seams present to attach said panel sections within said airbag are substantially straight.
