Abstract: A seam construction for a woven fabric for an OPW airbag, in particular for person restraint systems, which seam construction is characterized by a weaving seam having a single-layer region which is surrounded by an at least two-layer region, the individual layers of which have in each case a looser woven structure than the single-layer region.

Abstract: A fabric is described, in particular for an airbag, consisting at least partially of hollow filament yarns (K, S) made of a polymer material, wherein the fabric has a cover factor DG, according to Professor Walz, that is equal to the cover factor when using solid filament yarns of the same diameter.

Abstract: The invention relates to a method for the production of an air bag, more particularly a one-piece woven (OPW) air bag, comprising single layer and double layer areas, a top and bottom outer surface and a coating in at least certain areas. The invention is characteristic in that the single layer area is sealed in such a way that said areas are substantially impermeable to fluids.

Abstract: Fabric for an airbag, comprising warp threads and weft threads, in particular using multifilaments, characterized by a weave density greater than the 95% Professor Walz standard. It can also have a permeability (LD) of less than 3 l/dm2/min (at 500 Pa differential pressure) pursuant to ISO 9237, and can be characterized by a warp/weft insertion ratio greater than 1.

Abstract: A method for weaving fabrics that comprise in at least some sections multiple layers, especially one-piece woven (OPW) airbags comprising single-layer, double-layer and multi-layer sections. Weaves or weave combinations are produced in the double- or multi-layer sections that are different from the plain weave.

Abstract: A method for producing woven airbags, especially at least partially multi-layered airbags, includes the following steps: the warp threads are prepared in a warping room, warp threads which are suitable as marker threads for machine-readable markings being already placed in the warp; the airbag material is woven, weft threads which are suitable as marker threads for machine-readable markings being interlaced over at least part of the width of the cloth; and the airbag is cut out of the airbag material using a cutting device which is guided by the interlaced machine-readable markings.

Abstract: The available fabric mass in the one-piece woven airbag as tailorized by the method, now makes it possible to reinforce the airbag fabric individually oriented. Thus, at a high stress location formerly exhibiting airbag tears, a fabric quality is now available of enhanced resistance, achieved among other things by an increase in the thermal capacity in the neuralgic locations of the airbag where namely the jet lances feature their so-called jet gill zone.
