PURPOSE: To provide an inflator assembly for inflating an inflatable vehicle occupant restraint means, such as an air bag. CONSTITUTION: An inflator assembly 10 for inflating an inflatable vehicle occupant restraint means 12 includes a pressure vessel 14 with a storage chamber 18 containing a combustible mixture of gases. An ignitable material 122, when burning, ignites the combustible mixture of gases in the storage chamber 18. The storage chamber 18 has an axis 61, first and second opposite ends which are spaced apart from each other a distance along the axis 61, and a substantially circular cross sectional shape at all locations along the axis 61. The storage chamber 18 has a shape such that the ratio of the distance between the opposite ends of the storage chamber 18 to the greatest cross sectional diameter of the storage chamber 18 is within the range of 0.75-1.25.
