Patent ID: 6860511

Claim:
A gas generator comprising: a perforated housing defining an inner wall; a first perforated wall contained within said housing and forming a first combustion chamber, said first chamber having a first dimension and volume; a first gas generant composition within said first chamber, said first gas generant ignitable to provide a gas upon combustion thereof; a first igniter fixed within said first chamber for ignition of said first gas generant composition; a second perforated wall contained within said housing and forming a second combustion chamber, said second chamber having a second dimension and volume substantially equivalent to said first dimension and volume; a second gas generant composition within said second chamber, said second gas generant ignitable to provide a gas upon combustion thereof; a second igniter fixed within said second chamber for ignition of said second gas generant composition; a primary chamber defined by said housing inner wall, wherein contents of said primary chamber fluidly communicate with the combustion products of said first and/or second chambers upon activation of said gas generator; and a primary gas generant composition contained within said primary chamber for producing a primary inflating gas upon contact by the gas of said first and/or second chambers, wherein upon gas generator operation the first and/or second gas generant compositions are ignited to produce combustion products that upon exiting said first and/or second chambers, respectively, thereby ignites said primary gas generant composition.
