Abstract

A gas generator comprises a tubular housing of a pressure-resistant material and a propellant strand which is incorporated in the housing and provided with an envelope. At least one channel is provided between the envelope and the propellant strand so as to extend in an axial direction. The propellant strand has a substantially circular cross-section and the envelope has a polygonal cross-section.
