Method for manufacturing airbag module
First Claim
1. A method for manufacturing an airbag module for use in a motor vehicle, comprising:
- a first step of folding an airbag into a predetermined configuration;
a second step of wrapping an entire external surface of the airbag in an initially folded condition obtained in the first step by a bag-shaped film forming member, wherein the bag-shaped film forming member comprises a plurality of resin layers formed in a layer-stack manner with regard to a film cross-sectional direction; and
a third step of housing the initially folded airbag in an airbag-housing member in a condition wherein the airbag has an airbag volume reduced to less than that at a time of being initially folded, by a compression force applied to the bag-shaped film forming member.

Abstract
An airbag module for use in a motor vehicle is manufactured by first to third steps. In the first step, the airbag is folded into a predetermined configuration, and in the second step, an entire external surface of the airbag, in an initially folded condition obtained in the first step, is wrapped in a bag-shaped film forming member. The bag-shaped film forming member includes a plurality of resin layers formed in a layer-stack manner with regard to a film cross-sectional direction. In the third step, the initially folded airbag is housed in the airbag-housing member in a condition wherein the airbag has an airbag volume reduced to less than the airbag volume at a time of being initially folded, by a compression force applied to the bag-shaped film forming member.
