Abstract

A gas generator for inflating a safety bag for the protection of persons in a vehicle, is equipped with a combustion chamber that is divided into a smaller section and into a larger section by a sheet metal insert. The sheet metal insert also divides the fuel into two portions, whereby a smaller fuel portion is located closer to the ignition openings of an ignition device while the larger fuel portion is located further away from the ignition device. The divider or insert provides a passage or gas flow openings which are so located that the combustion gas generated in the smaller section must flow entirely through the smaller section before it enters into the larger section. Thus, the smaller fuel portion is combusted substantially first and the larger fuel portion is combusted thereafter to provide an inflation characteristic for the safety bag such that the bag is initially filled slower and then rapidly.
