Patent number: 8052169Abstract: A gas generator for inflating a gas bag of a vehicle occupant restraint system is provided. The gas generator includes an igniting means for producing gas and/or heat upon activation by a control signal of the vehicle. The gas generator also includes a first chamber comprising a propellant ignitable by gas and/or heat produced by the igniting means, and a second chamber comprising pressurized inflation gas. An outlet opening through which the inflation gas can flow out of the second chamber and into the gas bag is provided. The gas generator also includes a sealing means sealing the outlet opening.

Publication number: 20030025313Abstract: An inflator configured to operate so that during a predetermined time from start of operation thereof, the amount of gas supplied by the inflator is large, and, thereafter, the amount of gas supplied is reduced and wherein the gas is continued to be supplied for a long period of time. The inflator includes first and second gas flow openings and a valve mechanism that operates to selectively open the first gas flow opening. When gas is supplied to the gas flow openings at a pressure equal to or greater than a predetermined value, the valve mechanism opens the first gas flow opening. When the pressure of the gas supplied to the gas flow openings becomes equal to or less than a predetermined value, the valve mechanism closes the first gas flow opening.Type: ApplicationFiled: August 2, 2002Publication date: February 6, 2003Applicant: Takata CorporationInventors: Shoichi Sawa, Noriyuki Kosugi, Kanji Yano, Yuichi Nanbu
