Abstract
A hybrid gas generator for vehicle safety, systems, in particular airbag inflating and seat belt tensioning systems or pyrotechnical isolating switches for disconnecting the vehicle electrical system from the vehicle battery in the event of an impact accident, is described, whereby a moving piston is provided to destroy the bursting diaphragm which closes off the compressed gas container. This piston is moved towards the bursting diaphragm by igniting an ignition system whereby according to this invention the piston has a flange-shaped projection which is located against a shoulder on the internal surface of a sleeve facing the piston and is designed such that when the ignition system is ignited the flange-shaped projection shears off. Advantageously, the operating pressure in the combustion chamber of the hybrid gas generator according to this invention can thus be determined by the area of the shearing surface on the flange-shaped projection.
