Patent number: 8801029Abstract: An airbag includes a high pressure expansion chamber, a low pressure expansion chamber, and a communication passage, which connects the high pressure expansion chamber and the low pressure expansion chamber to each other. A gas supply port, which supplies inflation gas into the airbag, is located inside the low pressure expansion chamber to discharge the inflation gas toward the inside of the communication passage. The communication passage extends from the edge of a communication port, which connects the high pressure expansion chamber and the low pressure expansion chamber, toward the inside of the high pressure expansion chamber. At deployment and inflation of the airbag, the communication passage is located between a seam formed at the outer periphery of the base fabric sheet of the airbag and the gas supply port.Type: GrantFiled: June 28, 2013Date of Patent: August 12, 2014Assignee: Toyoda Gosei Co., Ltd.Inventors: Masashi Hotta, Yuji Sato, Kensaku Honda, Yoshiaki Goto, Takashi Iida, Akira Yamashita, Masaaki Okuhara

Publication number: 20140125041Abstract: An improved airbag assembly (20) has an inflator (40), an airbag (20) and a diffuser (70). The diffuser (70) is formed from two folded inner and outer pocket panel layers of fabric and sewn to the airbag (20). The folded inner pocket layer (71) is configured to fit inside the outer pocket layer (73) forming a two-layer structure. The fold (75) in the inner layer (71) is oriented in a first direction relative to the weave of the fabric and the fold of the outer layer (73) is oriented at a second direction relative to the weave of the fabric wherein the second direction is different from the first direction. The first direction and second direction of folds (75, 77) are inclined relative to the other so upon assembly the inner pocket layer (71) fabric weave is directionally inclined on a bias relative to the outer pocket layer (73) fabric weave.Type: ApplicationFiled: November 5, 2012Publication date: May 8, 2014Applicant: KEY SAFETY SYSTEMS, INC.Inventor: Bruce Andrew Kalandek
