Abstract
An air bag that includes a fold indicator to indicate whether the air bag has been properly folded within an air bag module. The indicator includes a plurality of marks disposed and spaced on an outer surface of the air bag in a predetermined pattern. The predetermined pattern is arranged such that when the air bag is properly folded the plurality of marks forms a folded pattern indicative of a properly folded air bag. The plurality of marks may be made from a material that is exposable by an x-ray such as a metallic coating. With such a construction, the air bag module, after it as been assembled, may be sent through an x-ray machine and examined as to whether the folded pattern of the marks of the air bag conforms to a standard pattern indicative that the air bag has been folded properly.
