Claim:
A method for folding an airbag for an airbag module, comprising: disposing the airbag on a support; providing at least one piling element for folding the airbag next to an exterior edge of the airbag disposed on the support; and folding the airbag together using the at least one piling element such that the piling element is moved so as to influence the edge of the airbag along the support in a direction toward an interior of the airbag disposed on the support, wherein at least one retainer protrudes from the at least one piling element, which is moved together with the piling element during the movement of the piling element for folding the airbag, wherein the airbag is prefolded before the at least one retainer movable together with the piling element acts on the airbag for folding the airbag, wherein the at least one retainer reaches over or under an edge area of the airbag before the at least one retainer movable together with the piling element acts on the airbag for folding the airbag, wherein the at least one retainer acts on the edge area of the airbag such that an undercut is formed in the airbag through an effect of the retainer on airbag sections of the airbag during the movement of the piling element for folding the airbag, and wherein, during formation of the undercut through the effect of the retainer on the airbag sections of the airbag, the airbag sections are located below and above the retainer when viewed along a direction vertical to the support.
