Method and device for folding an airbag for an airbag module
First Claim
1. 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, andwherein, 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.

Abstract
A method for folding an airbag for an airbag module in which the airbag is disposed on a support is provided. At least one piling element for folding the airbag is provided next to the exterior edge of the airbag disposed on the support. The airbag is folded together using the at least one piling element in that the piling element is moved along the support in the direction toward the interior of the airbag disposed on the support. A retainer protrudes from the at least one piling element and moving together with the piling element during the movement thereof and reaching over or under an edge area of the airbag. The at least one retainer acts on an edge area of the airbag in such a way that an undercut is formed in the airbag through the effect of the retainer.

8. A method for folding an airbag for an airbag module comprising:
-
disposing the airbag on a support; providing multiple piling elements for folding the airbag next to an exterior edge of the airbag disposed on the support; and folding the airbag together using the piling elements such that the piling elements are 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 a retainer protrudes from at least one of the multiple piling elements, which is moved together with the at least one of the multiple piling elements during movement of the piling elements for folding the airbag, wherein the retainer reaches over or under an edge area of the airbag before the at least one retainer moves together with the at least one of the multiple piling elements so as to fold the airbag, wherein the retainer penetrates during impact on the airbag during the movement of the at least one of the multiple piling elements and forms an undercut, wherein, during formation of the undercut through an effect of the retainer on airbag sections of the airbag, the airbag sections are located below and above the retainer as viewed along a direction vertical to the support. - View Dependent Claims (9, 10, 11, 12, 13, 14)
