Tuning the performance of compressed gas-containing inflators

摘要

An inflator apparatus wherein the molecular weight of the gas mixture therein contained is manipulated by varying the relative amounts of the various constituents thereof. Through such manipulation and tight control of gas mixture molecular weight, the performance of the inflator can be properly tuned such as to desirably control or influence the speed of deployment of an associated airbag cushion and minimize or reduce damage to an associated airbag cushion caused by excessive deployment speeds, as well as satisfy the relatively onerous inflation demands required for proper or desired operation of various close proximity airbag cushions or inflatable restraint devices.
