Abstract
The present invention relates to a gas generator (1) for a safety device for a motor vehicle, which comprises at least two distinct chambers respectively designated as first (2) and second (3) chambers, which communicate with each other through at least one opening or nozzle, the first (2) of these chambers being isolated from the outside, the second one (3) a so-called ‘diffusion’ chamber being able to receive gases generated by the combustion of a solid pyrotechnical charge (5) placed in the first chamber (2), and to discharge them towards the outside. It is remarkable in that: said solid charge (5) is a mixture consisting of at least one oxidizing charge and a reducing charge, the oxygen balance of which is equilibrated; a heat-generating means (6) is provided which generates sufficient heat for triggering and sustaining the combustion of said charge (5), this without any other interaction, notably of the chemical type, between this means (6) and this charge (5).

16. A gas generator for a safety device for a motor vehicle, the gas generator comprising:
-
at least a first chamber and a second chambers, the first chamber isolated from the outside, the second chamber in communication with the first chamber; an energetic charge disposed in the first chamber, the energetic charge being a mixture of at least one oxidizing charge and one reducing charge for which the oxygen balance of the reaction products is equilibrated; and a heat-generating device for generating sufficient heat for triggering and sustaining the combustion of the energetic charge without any other interaction, notably of a chemical type, between the heat generating device and the energetic charge; wherein the second chamber receives gases generated by reaction of the energetic charge within the first chamber and the gases are discharged via at least one discharge aperture of the second chamber that is in communication with the outside. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30)
