1. An inflator comprising:
- a pressure vessel (22) in which inflation gas is stored;
the pressure vessel including a first opening (114), pyrotechnic means (42,
130) situated remote from the pressure vessel for generating products of to heat the inflation gas, a first burst disk means (160, 150, 150'"'"') mounted to the pressure vessel to seal the first opening thereof after the pressure vessel has been charged to a determinable pressure with inflation gas and in communication with the pyrotechnic means such that the products of combustion assist in the opening of the first burst disk means.

13. An inflator comprising:
a pressure vessel (22) in which inflation gas is stored;
the pressure vessel including a first opening or fill port (114) through which inflation gas is placed into the pressure vessel, pyrotechnic means (42,
130) for generating products of combustion to heat the inflation gas, a first burst disk means (160, 150, 150'"'"') mounted to the pressure vessel to seal the first opening thereof after the pressure vessel has been charged to a determinable pressure with inflation gas, the first burst disk means is opened at least partly in response to the products of combustion produced by the pyrotechnic means.- View Dependent Claims (14)
