Textile formed part having pre-determined three-dimensional shape
First Claim
1. A textile formed part that is manufactured by a method that comprises the concurrent steps of:
- (a) fusing a fusible polymer material comprising a plastic film to at least one layer of textile fabric material, wherein the melting point of said fusible polymer material is lower than the melting point of said textile fabric material, between forming tools to form a multilayered textile composite; and
(b) thermally forming said multilayered textile composite in a three-dimensional shape corresponding to a desired profile.

Abstract
An invention relates to an inflatable gas bag (10) for an occupant restraint system of a vehicle, in particular of a motor vehicle. In order to avoid the formation of creases in the inflated state, which occurs with conventional gas bags and in order to be able to employ more lightweight textile materials for the manufacture of a gas bag, the gas bag (10) consists of a multilayered textile composite material which comprises at least one layer of a textile material and one layer of a polymer material whose melting range is lower than the melting range of the textile material. The textile composite material is formed into a specified three-dimensional shape which is to develop during inflation of the gas bag (10), and the individual layers of the textile composite material are joined together in this three-dimensional shape.
