The present invention relates to a method and a device for making the combustion of a pyrotechnic compostion independent of the ambient temperature when combusting a pyrotechnic composition in a preinflator or combustion chamber ( 2 ) incorporating outlets but being otherwise enclosed. As claimed in the present invention this is enabled by controlling the burning pressure of the pyrotechnic composition so that it does not exceed a predetermined value. The characteristic feature of the present invention is that the preinflator ( 2 ), in which combustion of the pyrotechnic composition takes place, incorporates a plurality of gas discharge perforations ( 6-9 ) or outlets, each of which is initially sealed by a bursting disc or foil seal ( 10 ) that is designed to rupture when the said burning pressure in the combustion chamber ( 2 ) is exceeded. |
