Abstract
An inflator having a base containing a diffuser and a canister having a chamber for receiving and holding gas under pressure are inserted in aligned, separated position in a pressure chamber. The pressure chamber is closed, sealed and filled with gas, thereby filling the canister. When the gas fill reaches the desired pressure, an integral top press is activated, thereby joining the base with the filled inflator canister. The base is then welded or crimped to the inflator chamber, thereby assembling a complete airbag inflating device.
