A gas generator comprises a tubular housing of a pressure-resistant material and a propellant strand which is incorporated in the housing and provided with an envelope. At least one channel is provided between the envelope and the propellant strand so as to extend in an axial direction. The propellant strand has a substantially circular cross-section and the envelope has a polygonal cross-section.

Tubular gas generator

An airbag system for a motor vehicle, characterized in that a separate cable-type gas generator ( ) is associated with the individual chambers ( ) of said air bag system extending in the form of a harness from a central initiator ( ) to the respective inflatable chamber ( ) of said airbag system.

Motor vehicle air bag system with a cable-type gas generator

The invention relates to a cord-type gas generator, comprising a solid propellant strand ( ) consisting of a gas-generating material, located in a sleeve ( ) and a detonation element ( ). The solid propellant strand ( ) is positioned in the sleeve ( ) in such a way, that continuous channels ( ) are configured between the sleeve ( ) and the solid propellant strand ( ) for the formation of a detonation shock wave. The gas generator is characterised in that the solid propellant strand ( ) has a reduced woven thickness (W), achieved by the introduction of gaps into the material (slits , pores ), in order to reduce its burn time.
