A gas generator for inflating safety cushions in automotive vehicles has a tubular housing, closed at both ends except for a discharge orifice in one end. A hermetically sealed container in the completely closed end of the housing is divided by a consumable partition into two chambers containing gas generant material. Each of the two chambers is also equipped with an ignition means for igniting the gas generant. The remainder of the tubular housing is filled with the following elements, arranged in tandem series from the sealed container to the orifice of the housing: a filtering means, a first perforated plate, pH neutralizing material, a second perforated plate, cooling means, and a third perforated plate. An impact sensor, which is not a part of the present invention, determines whether one or both of the ignition means are fired on impact, depending upon the force of a collision; and, hence, the rate at which an inflatable structure is filled with gas.
In a gas generator for delivering gas to an inflatable structure in response to a sensor, said generator including a housing having an outlet orifice in communication with said inflatable structure, a gas generant material in said housing, and filtering and cooling means between said gas generant material and said orifice, the improvement comprising:
