摘要： 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.

摘要： A method is provided for filling an enclosure with an ignitable mixture of gases. The enclosure has an outer wall comprising an exterior surface, an interior surface, and a fill aperture extending therethrough. The method comprises delivering a predetermined amount of pressurized combustible gas into the enclosure through the fill aperture, delivering a first predetermined amount of pressurized inert gas into the enclosure through the fill aperture at a first pressurization rate, delivering a second predetermined amount of pressurized inert gas into the enclosure through the fill aperture at a second pressurization rate, welding a sealing member to the outer wall of the enclosure by a welding process to form a weld operable to seal the fill aperture and to permit the enclosure to store pressurized gas therein. The first pressurization rate allows the first predetermined amount of pressurized inert gas to mix with the predetermined amount of pressurized combustible gas to form an ignitable mixture. The second pressurization rate is lower than the first pressurization rate. The second pressurization rate allows stratification to form within the enclosure between a layer of the ignitable mixture and a layer of the second predetermined amount of pressurized inert gas. The layer of the second predetermined amount of pressurized inert gas is disposed between the layer of the ignitable mixture and the fill aperture.
