Abstract

An inflator has a tubular member with a sealing element hermetically sealing the open end of the tubular member. The tubular member and the sealing element form a pressure vessel for storing inert gas. The inflator has a support member for supporting the sealing element. The support member prevents the forces associated with the inert gas from driving the sealing element apart from the tubular member. During a crash situation, the support member is displaced, which allows the inert gas to burst the sealing element. Consequently, the inert gas has an unobstructed path to flow out of the inflator.
