Abstract
An air bag (10) for use with an inflation fluid source (34) includes a body portion (170) defining an inflation fluid volume (172) into which inflation fluid is directed to inflate the body portion. A mouth portion (160) of the air bag (10) is connected with the body portion (170). The mouth portion (160) defines an inflation fluid opening (176) in fluid communication with the inflation fluid volume (172). The inflation fluid opening (176) is defined in part by opposite fabric material panels (40, 42). Each panel (40, 42) comprises at least two layers (130, 132, 140, 142) of fabric material in abutting engagement with each other. At least two layers (130, 132, 140, 142) of fabric material encircle a retaining ring (174) for attaching the air bag mouth portion (160) to the inflation fluid source (34).
