A gas generator has a gas generating combustion chamber with an igniter or fuse for igniting an ignitable charge needed for the gas generation. At least one filter housing is attached to the gas generating chamber. The generated pressurized gases enter into the filter housing in one direction, for example an axial direction, and pass out of the filter in another direction, for example in a radial direction, under the influence of a gas flow distribution member which makes sure that the filter volume is efficiently used by uniformly distributing the gas volume throughout the filter volume. The gas exiting from the filter housing inflates a safety bag for the protection of persons in a vehicle.

A gas generator, especially for inflating a safety bag, comprising gas generating means including a combustion chamber for producing a gas for said inflating, a filter housing connected to said combustion chamber, means for passing gas produced in said combustion chamber into said filter housing in a first axial direction, ring filter means having a given filter volume and a central cavity located in said filter housing, so that produced gas enters into said central cavity, said filter housing having a housing wall with radially facing gas exit means in said housing wall, so that gas entering said cavity in said first axial direction must pass through said ring filter means and out through said gas exit means in a second radial direction, and axially effective gas flow distribution means in said cavity for substantially uniformly distributing axially in-flowing gas over a ring filter surface facing said cavity, said gas flow distribution means comprising a plurality of gas flow influencing elements for converting an axial gas inflow into a radial turbulent gas outflow which is substantially uniformly distributed onto said ring filter surface for efficiently using substantially all of said given filter volume of said ring filter means.
