ABSTRACT:
An air bag occupant protection device for use in motor vehicles having an air bag made from a single piece of flat foldable fabric material. The air bag according to this invention is formed by gathering the free edge of a flat piece of sheet stock to define radial pleats at a small opening provided for inflation gases to enter the inside of the bag. Various approaches for gathering the free edge of the material are disclosed including the use of a retaining ring having posts which engage apertures in the free edge of the material, a cord for gathering the free edge, and various other means of gathering the edge and sewing it in place. The invention avoids the cost of fabricating an air bag from multiple pieces of cut fabric and further avoids the failure modes of a fabricated air bag caused by the presence of seams which can constitute a local weakness in the air bag assembly.
