20090001698 | PRESSURE CONTROL APPARATUS OF AIR BAG - Disclosed is a pressure control apparatus of an airbag, which can obtain the same performance as in case of using a dual stage inflator even in case of using a single stage inflator deploying an airbag cushion by an explosive force of an explosive charge caused by the ignition of one igniter by having a pressure control apparatus for selectively communicating the interior of an airbag cushion and the exterior of an airbag housing without using the dual stage inflator deploying the airbag cushion by an explosive force of an explosive charge caused by the ignition of two igniters. | 01-01-2009 |
20090020990 | VENTING DEVICE FOR AN AIRBAG INFLATOR - A device for supporting a rupturable closure member of a pressure vessel, such as an airbag inflator has a hollow support with a tapered portion and an adjoining cylindrical portion. An exterior surface of the tapered portion has longitudinally extending grooves therein. An igniter is located adjacent the cylindrical portion of the support and a pyrotechnic substance is located in the cylindrical portion of the support between the igniter and the tapered portion of the support. A rupturable closure member being forced against an open first end of the tapered portion of the support by the gas in the pressure vessel such that a chamber is formed within the support. The igniter when activated ignites the pyrotechnic substance and the burning pyrotechnic substance generates gas under pressure that causes the tapered portion of the support to break along the longitudinally extending grooves and no longer support the rupturable closure member allowing the gas in the pressure vessel to rupture the unsupported rupturable closure member. | 01-22-2009 |
20090058059 | AIRBAG INFLATION WITH SLIDING BAFFLE - A new type of airbag inflator is described. The airbag inflator includes a chamber that houses a quantity of inflation gas.

The sliding baffle is positioned proximate the membrane. The sliding baffle has a membrane rupture mechanism and a plurality of gas flow holes. Upon initiation of the inflator, the sliding baffle slides to cause the rupture mechanism to fail the membrane. The rupture mechanism fails the membrane by detaching a single piece from the membrane. The single piece is sufficiently large such that it remains within the inflator (or within the sliding baffle) and does not pass through one of the gas flow holes. | 03-05-2009 |

20090283996 | System for tuning initial onset - A deployable inflator that includes a quantity of gas generant. The generant is designed to produce a supply of inflation gas during deployment of the inflator. The inflator includes a first burst disk and a second burst disk. The first and second burst disks are separated by a cavity. The inflator also includes an opening (or multiple openings). During deployment, the inflation gas flows into the cavity via the opening(s) and ruptures the first burst disk to allow inflation gas to escape the inflator. The second burst disk ruptures after the pressure in the cavity drops sufficiently below the pressure on the other side of the second burst disk. This inflator reduces the initial onset rate of deployment. | 11-19-2009 |

20100078922 | Inflator bottle for combustible gas mixture - An inflator bottle adapted for controlled release of product gas to deploy an inflatable cushion and a method thereof is provided. The inflator bottle comprises a compartment filled with a combustible gas mixture having a partition that divides the compartment into a first region and a second region. Upon a crash event, an igniter on the inflator bottle ignites initiating combustion in the first region. Combustion propagates in the first region toward a nozzle building pressure in the first region sufficient to rupture a burst disk over the passage of the nozzle releasing product gas through the nozzle. The release of product gas through the nozzle draws combustible gas mixture from the second region flowing through the gas portal on the partition into the first region for combustion. The area of the gas portal between the regions is sized in relation to the size of the minimum area of the passage of the nozzle to supply the combustible gas mixture to the first region at a rate that maintains the flame front while preventing it from propagating out into the second region or out the nozzle until the remaining combustible gas mixture in the compartment is consumed. | 04-01-2010 |

The rupture membrane is upstanding from the inflator wall about the egress opening to a constant height. The rupture fragment and the rupture membrane are integrally-formed with each other and with the inflator wall at the egress opening. The pressure impulse impacts the rupture fragment, urges the rupture fragment away from the inflator, detaches the rupture fragment from the inflator by fully transversely fracturing the rupture membrane, and drives the rupture fragment into containment within the diffuser. | 07-14-2011 |
