An inflator device for a passive restraint device, such as an airbag, and methods of inflating an airbag. In certain aspects, an initiator device is provided in a housing. The initiator device includes at least one chemical hydride compound. Upon initiator actuation, an enhanced shock wave generated by the initiator device opens a temporary closure between the inflator housing and the downstream airbag to permit gases to flow into the airbag. Released hydrogen reacts with oxygen from a stored pressurized gas, and combustion products of the initiator device flow into the airbag for rapid inflation. |
