Abstract
A gas generator for a safety device for a motor vehicle, comprises at least two distinct chambers which communicate with each other through at least one opening or nozzle. A first chamber is isolated from the outside. A second chamber or 'diffusion' chamber is able to receive gases generated by the combustion of a solid pyrotechnical charge placed in the first chamber, and to discharge them towards the outside. The solid charge is a mixture consisting of at least one oxidizing charge and a reducing charge, the oxygen balance of which is equilibrated. A heat generator is provided which generates sufficient heat for triggering and sustaining the combustion of the charge without any other interaction, notably of the chemical type, between the heat generator and the charge.
