Abstract
A gas producer is disclosed for filling a gas cushion restraining device for occupants of vehicles. The gas producer includes a combustion chamber filled with fuel and surrounded by a wall which exhibits apertures for the discharge of the gas produced, said apertures being sealed hermetically by a destructible cover at the start of the burning process of the fuel up to a specific pressure rise in the combustion chamber. In order to obtain a planned pressure rise irrespective of the initial temperature of the gas producer, it is provided according to the invention that the total cross-sectional area of the discharge apertures is automatically enlargeable as a function of the rising combustion chamber pressure.
