<p>A gas generator comprising:•- a chamber (10) of pressurised gas stored at a first temperature, and comprising a discharge port (11) sealed by a lid (12),•- an igniter (20) arranged to generate a pressure wave in the pressurised gas chamber,•- a propellant charge (30) arranged at least in a portion of the pressurised gas chamber (10), the propellant charge being arranged to be ignited by the igniter and to generate combustion gases at a second temperature higher than the first temperature, the pressure wave being predetermined to open the lid such that at least a portion of the gases pressurised at the first temperature exit the chamber (10) before the combustion gases generated by the propellant charge (30) at the second temperature, characterised in that at least a portion of the propellant charge is arranged between the igniter (20) and the discharge port (11) and is traversed by the pressure wave that is generated by the igniter and opens the lid (12).</p> |
