Abstract

A gas flow distributor for an airbag module for the specific distribution of a gas flow through which the released gas flows during inflation of the airbag is provided. The gas flow distributor comprises at least two sleeve parts which are made of a flexible material and are connected to one another by a seam. The seam absorbs the forces which are exerted on the sleeve by the gas flowing through it. An additional releasable connection of both sleeve parts is provided in at least some sections in order to absorb the forces exerted by the gas on the sleeve, wherein the additional connection cooperates with the sleeve for limiting the forces to be absorbed by the seam in such a manner that said connection is released when gas passes through the sleeve.
