The invention concerns a tubular gas generator for the filling of an airbag in a retention system for occupants of motor vehicles, whereby two separate combustion chamber units have a common connector and each combustion chamber unit has an ignitor unit with respective filters.

Pyrotechnic gas generator with two separate combustion chambers

Gas generators for passive restraint systems in motor vehicles, particularly for airbag systems or belt pre-tensioner systems, contain a gas generating compound which is ignited by an electrical ignition unit. The present ignition unit makes do with a small number of individual components and does not employ a plug. The connecting devices carrying the electrical ignition pulse are connected directly to the ignition charge without the intermediate circuitry of a plug, and the ignition carrier is formed as an enclosure for the connecting devices.

Gas generator ignition unit for a passive restraint system

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.

Hybrid gas generator for safety systems in road vehicles

For the purpose of reducing manufacturing costs and mounting defects, an electric ignition device has a one-piece basic body as a base for a primary and a secondary charge, so that the tightness is also increased with respect to moisture penetration.

Ignition device

The innovation relates to an electric ignitor for a pyrotechnic element hng a rotationally symmetrical electrical plugging arrangement comprising two plug elements connected together and with a short-circuiting spring being open in the progress.
