Gas generator arrangement

A gas generator apparatus for generating gas for inflating a motor vehicle airbag, comprising:

• an ignition device including a first housing and a first pyrotechnic charge disposed in said first housing;
• a gas generator including a second housing having an opening, a sealing membrane covering the opening for hermetically sealing the second housing and being located adjacent to the first pyrotechnic charge in the first housing, a second pyrotechnic charge located in the second housing adjacent to said membrane, a gas generating pyrotechnic material arranged in said second housing to be responsive to a combustion of the second pyrotechnic charge, and a flame guide located between the second pyrotechnic charge and the gas generating pyrotechnic material for directing the flame from the second pyrotechnic charge to the gas generating pyrotechnic material, said flame guide comprising a substantially tubular wall for separating a path for the flame from a region containing the gas generating pyrotechnic material, the substantially tubular wall having openings therein;
• wherein a combustion of the first pyrotechnic charge initiates a combustion of the second pyrotechnic charge through said membrane which in turn initiates combustion of the gas generating pyrotechnic material.
