Method for manufacturing a woven fabric for an airbag for passenger restraint systems for motor vehicles, characterized via the steps of preparing a group of warp yarns composed of warp yarns () of different yarn qualities, having first warp yarns () and having second warp yarns () which are arranged in selected regions (ZK) of the group of warp yarns and are made of hybrid yarn which has first filaments () and second filaments (), weaving the fabric with at least one weft yarn quality, and thermal, mechanical or chemical treatment of the fabric in such a way that the second filaments lose their filament structure, become an amorphous mass and connect the first filaments to one another.

Airbag and method for manufacturing a fabric for an airbag

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.

Fabrication of air bag fabric

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.
