Abstract
An airbag inflator comprises a housing having an interior and gas outlet ports communicating with the interior and open to outside the housing. First and second divider walls separate an inflation gas chamber and an initiator gas chamber from the interior. A pressurized inflation gas is stored in the inflation gas chamber. A pressurized combustible gaseous mixture is stored in the initiator gas chamber. An initiator is disposed within the initiator gas chamber and actuatable to ignite the pressurized combustible gaseous mixture. The second divider wall defining the initiator gas chamber is supported by the pressurized combustible gaseous mixture and resiliently deformable to force the first divider wall to rupture, permitting a flow of the pressurized inflation gas from the housing though the gas outlet port in response to actuation of the initiator.
