20090267334 | Airbag inflator with adaptive valve - An adaptive valve for an airbag inflator having a manifold with an exhaust opening for fluid communication with an airbag. The adaptive valve is constructed for connection to a manifold so that it is in fluid communication therewith. The adaptive valve has an exhaust orifice and is constructed to selectively open the exhaust orifice to divert inflation gas away from an inflator manifold when it is connected thereto to lower the rate of inflation of an airbag in fluid communication with the exhaust opening of the manifold. The adaptive valve may have a valve member movably mounted therein for movement between a first position wherein it closes the exhaust orifice and a second position wherein it opens the exhaust orifice. An initiator is provided in the adaptive valve to generate sufficient gas pressure to move the valve member to the first or second position. | 10-29-2009 |
20100230942 | Solid propellant/liquid type hybrid gas generator - A gas generator comprising a housing having a mixing chamber and a pyrotechnic charge in the housing. A container having a liquid therein is disposed in the housing and has an open end and a closed end, with an end cap closing the open end and having a piston portion removably connected thereto and being movable within the liquid container to pressurize the liquid therein when the piston portion is separated from the end cap. The piston portion is positioned to be exposed to combustion gas from the pyrotechnic charge when it is ignited and is separable from the end cap when the combustion gas exceeds a predetermined pressure. In another embodiment, the liquid container may be a collapsible tube. The closed end of the liquid container has a weakened portion constructed to be opened when the pressure of the liquid in the container exceeds a predetermined pressure. The pyrotechnic charge and the weakened portion of the liquid container are in fluid communication with the mixing chamber so that combustion gases from the ignition of the pyrotechnic charge mix with and vaporize the liquid in the mixing chamber to generate a non-toxic, low temperature, low particulate inflation gas. | 09-16-2010 |

20130305516 | AIR BAG HEAT SINK/FILTER SECURING METHOD AND APPARATUS - A method and apparatus for securing a heat sink/filter positioned between a pressure vessel and a diffuser in an air bag inflator. The pressure vessel is constructed so that upon activation of the inflator of the area of gas exiting the pressure vessel is smaller than the area of gas exiting the diffuser to create pressures in the pressure vessel that are higher than the pressures in the diffuser. This results in deformation of the pressure vessel that is equal to or greater than the deformation of the diffuser to maintain compression of the heat sink/filter between the pressure vessel and the diffuser during activation of the inflator. | 11-21-2013 |
20130306653 | GRAIN RETAINER CONSTRUCTION FOR AIR BAG INFLATOR - A propellant grain retainer for an air bag inflator having a pressure vessel. A cantilevered finger is mounted in the pressure vessel and a propellant grain is mounted thereon. Upon assembly of the pressure vessel, the finger is deformed inwardly away from an adjacent wall of the pressure vessel to increase the air gap between the pressure vessel wall and the propellant grain to reduce heat transfer therebetween and increase the safety of the inflator. | 11-21-2013 |
20150096653 | AUTOIGNITION FOR IGNITING GAS-GENERATIVE COMPOSITIONS USED IN INFLATOR DEVICES FOR PROTECTIVE PASSIVE RESTRAINTS - An autoignition composition for a gas generant for an airbag or the like.
