Abstract
An inflation system for automotive airbags which comprises a pyrogenic solid grain with igniter strips provided in grooves on its external surface. Upon ignition, the solid grain burns from its external surface inwardly while allowing the generated gas to pass freely from its external surface. Preferably both the pyrogenic solid grain and the igniter strips are extrusions, providing a simplified, less expensive manufacture.
