<p>A device is provided for increasing the surface area of the gas generant used in an automotive safety air bag module (50). Depending on crash conditions, the surface area of the gas generant is increased by shattering the gas generant wafers (80). One embodiment utilizes a squib having a high brisant zone which upon activation shatters the gas generant wafers. Alternatively, a dual function squib (104) is used which can produce mechanical forces which force a breaking object (108) to impact on the gas generating wafers thereby shattering them and increasing the surface area of the gas generant. <IMAGE></p> |
