A device is provided for increasing the surface area of the gas generant used in an automotive safety air bag module. Depending on crash conditions, the surface area of the gas generant is increased by shattering the gas generant wafers. One embodiment utilizes a squib having a high brisance zone which upon activation shatters the gas generant wafers. Alternatively, a dual function squib is used which can produce mechanical forces which force a breaking object to impact on the gas generating wafers thereby shattering them and increasing the surface area ...


A gas generator for inflating a vehicle inflatable restraint cushion, said gas generator comprising: a housing including a tubular combustion chamber having first and second end portions; means for closing said end portions; a gas generating material formed into a plurality of gas generating wafers, arranged along the length of said tubular combustion chamber and spaced from each other in a side-by-side array; wafer shatter means in spaced relationship with at least a first of said gas generating wafers; at least one igniter means for igniting said gas g...
