A method for folding an airbag includes folding the airbag into an elongate state at least partially by roll-folding. The method also includes inserting a gas generator and/or an airbag-retaining metal sheet into the airbag. The gas generator and/or the airbag-retaining metal sheet is/are located in the central third of the airbag folded in elongate shape so that two end portions of the airbag project from the gas generator and/or from the airbag-retaining metal sheet. The method also includes guiding the airbag end portions around the outer circumference of the gas generator and/or of the airbag-retaining metal sheet in opposite directions toward each other up to a folding zone in which the end portions of the airbag at least almost contact each other. The method further includes folding over the end portions of the airbag from the folding zone outwards and guiding the airbag end portions in the opposite direction around the outer circumference of the gas generator and/or of the airbag-retaining metal sheet and around internal parts of the airbag end portions located thereon for forming external parts.
A method for folding an airbag comprising the following steps of:
An airbag module comprising a gas generator and an airbag in which the gas generator is located, wherein the airbag is laid into plural folds, at least a portion of which are roll-folded, extending in parallel to each other so as to form an elongate package in an intermediate state, wherein the gas generator, related to the length of the parallel folds, is positioned in the central third in the airbag, and wherein the outer thirds form airbag end portions of the airbag being folded into at least two parts, wherein two internal parts extend along the outer circumference of the gas generator toward each other up to a folding zone and wherein a respective external part of each airbag end portion is folded over outwards starting from the folding zone and extends along its associated internal part in the opposite direction.
