Abstract: The invention relates to a method for accommodating an airbag of an airbag apparatus into a container. The folding method employed allows the airbag to folded into a small container, yet ensures that the airbag will inflate in a substantially uniform and jerk-free manner. The method is still fairly cost effective. A preferred embodiment encompasses inserting a first plunger into an opening in a lower half of the airbag such that it pushes the upper part away from the lower part. The upper part is then clamped between the first plunger and a second plunger. Next, the airbag is folded upward such that a plurality of radial folds is created, which are then folded inward. A hollow die is then placed over the folded airbag. The upper end of the airbag and a central portion of the airbag are twisted in different directions while a third plunger is placed over the end face of the folded airbag. The third plunger is then used to compress the airbag.
