Abstract
By providing a cover of heat-resistant fabric over a pressure tank of a gas generator for an airbag, the objective can be attained that the outer exposed surface of the covered gas generator is not heated up to an excessive degree. Moreover, due to this feature, the proportion of solid and liquid, hot particles in the gaseous streams discharged from the gas generator can be additionally reduced.
