Gas flow distributor for an airbag module
First Claim
1. A gas flow distributor for an airbag module for the specific distribution of gas released from a gas generator into an airbag upon inflation of the airbag, said gas flow distributor comprising a flexible sleeve through which the released gas flows upon inflation of the airbag and which comprises at least two sleeve parts out of a flexible material connected to each other by means of a seam, wherein the seam takes up forces which are exerted on the sleeve by the gas flowing through the sleeve, whereinan additional releasable connection of the two sleeve parts is provided at least in sections for taking up the forces exerted by the gas on the sleeve,the additional releasable connection cooperates with the sleeve for limiting the forces to be taken up by the seam such that said additional releasable connection is released when gas flows through the sleeve,the sleeve comprises a first section and a second section connected thereto such that gas can flow through the first section and into the second section, wherein the second section includes two opposing exhaust ports through which gas can enter an airbagthe first section of the sleeve runs under an acute angle into the second section of the sleeve, andthe additional releasable connection connects the two sleeve parts to each other in a transition region of the sleeve at which the first section of the sleeve runs into the second section of the sleeve, so that a majority of the gas flowing through the sleeve exits the gas flow distributor through one of the two exhaust ports before a release of said additional releasable connection.

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.
