GAS GENERATOR ASSEMBLY WITH GUIDE ELEMENT
First Claim
1. A gas generator assembly for an airbag module of a motor vehicle, comprisinga generator housing with a first housing part and a second housing part,a combustion space formed in the generator housing for accommodating a pyrotechnic charge from which a gas for inflating a gas bag of the airbag module can be generated by combustion,at least one outlet opening of the generator housing, through which gas generated in the combustion space can be released for inflating the gas bag,at least one filter unit arranged in the generator housing for filtering the gas generated from the pyrotechnic charge, anda guide element arranged in the generator housing, by means of which the generated gas is guided to the at least one outlet opening,wherein the guide element is of tubular form and has at least one deformation area by which the guide element bears against the second housing part of the gas generator assembly in order to block a flow path by which gas generated in the combustion space would get to the at least one outlet opening without passing the at least one filter unit, wherein the at least one deformation area has been produced after an insertion of the guide element into the generator housing.

Abstract
A gas generator assembly for an airbag module of a motor vehicle, including a generator housing with a first housing part and a second housing part, a combustion space formed in the generator housing for accommodating a pyrotechnic charge from which a gas for inflating a gas bag of the airbag module can be generated by combustion. At least one outlet opening is provided in the generator housing through which gas generated in the combustion space can be released for inflating the gas bag. At least one filter unit is arranged in the generator housing for filtering the gas generated from the pyrotechnic charge. The assembly includes a guide element arranged in the generator housing, by means of which the generated gas is guided to the at least one outflow opening. The guide element is of tubular form and has at least one deformation area.

13. A method for manufacturing a gas generator assembly, comprising a generator housing with a first housing part and a second housing part, a combustion space formed in the generator housing for accommodating a pyrotechnic charge from which a gas can be generated by combustion, and at least one outlet opening through which gas generated in the combustion space can be released for inflating a gas bag, and at least one filter unit arranged in the generator housing for filtering the gas generated from the pyrotechnic charge, wherein in the generator housing a guide element is arranged, by means of which gas generated In the combustion space can be guided to the at least one outflow opening,
wherein the guide element is of tubular form and is deformed after being arranged in the generator housing, so that it bears against the second housing part of the gas generator assembly in order to block a possible flow path of gases generated in the combustion space to the at least one outlet opening.
