ASSEMBLY COMPRISING A DIFFUSER AND A GAS GENERATOR, AIRBAG MODULE AND METHOD FOR INSTALLING AN ASSEMBLY

In an assembly () of an elongate inflator () which has an outer housing () with outflow openings () spread along the circumference (U) and defining an outflow area () and an outflow direction, and of a clamp-type diffusor () enclosing the outflow area (), the diffusor () includes a central receiving opening () into which the outer housing () protrudes so that the diffusor () circumferentially encloses an axial portion of the outer housing () which comprises the outflow area (). At the inner side of the diffusor () delimiting the receiving opening () at least one bearing surface () and at least one gas guiding surface () are provided, wherein the bearing surface () bears directly against the outer housing () of the inflator () and the gas guiding surface () is radially spaced apart from the outer housing () while forming at least one collecting chamber () into which gas flowing out of the outflow area () is flowing. The collecting chamber () opens into at least one outlet opening () through which gas exits the diffusor () in an outlet direction (R) transversely to the outflow direction out of the inflator ().
