Inflator module for inflating an airbag with gas including an elongate housing, an elongate block of propellant arranged in the housing and generating gas when burning and preferably, igniter material arranged on the propellant. The igniter material is substantially coextensive with the propellant in a longitudinal direction such that upon ignition of the igniter material, the propellant begins to burn across its entire length. This is beneficial as the pressure generated by the gas may be substantially uniform provided the propellant is uniformly distributed and homogeneous. The igniter material may be arranged on portions of the propellant not in contact with the housing such that the propellant is completely enclosed by the housing and igniter material, i.e., not exposed to the ambient atmosphere.
