Abstract

A method for packing an inflatable airbag of a passenger restraint system of a motor vehicle into a housing, wherein the airbag includes a fabric envelope stored in a housing when not in use and is automatically inflated by a gas generator into a form of use when activated, includes the steps of firstly bringing the airbag into the form of use and secondly contacting the airbag in the form of use by mechanical folding aids and pushing the mechanical folding aids into the airbag. At least one first fold is formed so as to be arranged in a single fabric layer on the gas generator so that gas, produced by the gas generator for inflating the airbag when activated, directly impacts on the single fabric layer of the at least one first fold without flowing along other fold surfaces.
