  • Textile formed part having pre-determined three-dimensional shape
    Patent number: 6659501
    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.
