ABSTRACT:
A sequencing system is provided for varying the output of an inflator in a vehicle safety restraint system. The inflator has a housing including at least one combustion chamber. Gas generant for producing an inflation gas is disposed in the housing. Ignition material for igniting the gas generating means is disposed in the at least one combustion chamber. A first electric squib is disposed in the inflator housing for initially igniting the ignition material. At least one additional electric squib is disposed in the inflator housing for further igniting the ignition material. A delay sequencing unit is disposed outside of the inflator housing for activating the at least one additional electric squib after a predetermined time from the activation of the first electric squib. Upon activation of the first electric squib by an electrical pulse, an initial amount of inflation gas is generated and the electrical pulse is also received by the delay sequencing unit. After the predetermined time the electrical pulse is allowed to flow to the at least one additional electric squib and an additional amount of inflation gas is generated.
