US 6,786,507 B2 · Hybrid gas generator

Abstract

A hybrid gas generator comprises a chamber that contains pressurized fluid and that is sealed off by a rupturable membrane, and a pyrotechnical propellant charge that ruptures the membrane when it is ignited. The gas generator further comprises a nozzle wall that is arranged between the propellant charge and the membrane and that has at least one passage opening through which combustion products generated upon ignition of said pyrotechnical propellant charge flow towards the membrane. The passage opening has such a shape and is oriented with respect to the membrane in such a way that, when the membrane is ruptured, there are formed sections of said membrane that remain all connected to an edge of the membrane.
