A hybrid inflator apparatus (10) for inflating a vehicle occupant protection device comprises a container (12). A gas (30) is stored in the container (12) under pressure. A body (80) of ignitable material is stored within the apparatus (10), also under pressure. An igniter (50, 60) ignites the body (80) of ignitable material. The body (80) of ignitable material consists essentially of a solid organic polymer which is self-combustible at the pressure under which it is stored. Preferably, the organic polymer is self-extinguishing at atmospheric pressure and is formed, for instance by extrusion or molding, into a shape comprising at least one passage extending through the body. A preferred organic polymer is a cured glycidyl azide polymer (GAP). The stored gas (30) preferably comprises an inert gas which may be mixed with a small amount of oxygen.
