Embodiment Construction

[0025] Since the machines, tools, devices and materials required to perform the method according to the present invention are well known to those skilled in the art, they will not be described or shown in detail below.

[0026] The invention mainly comprises a method of manufacturing a knitted fabric for an airbag of a vehicle occupant restraint system, which method is characterized by the following steps:

[0027] An array of warp yarns is prepared from warp yarns of different yarn qualities, the array comprising first warp yarns and second warp yarns arranged at selected positions of the warp yarn array comprising mixed yarns comprising first filaments and second filaments. within a given section;

[0028] weaving the fabric with at least one weft quality;

[0029] The fabric is thermally, mechanically or chemically treated to cause the second filaments to lose their filament structure to become amorphous and to interconnect the first filaments to form monofilament-type fil...

Abstract

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 (24, 26) of different yarn qualities, having first warp yarns (24) and having second warp yarns (26) which are arranged in selected regions (ZK) of the group of warp yarns and are made of hybrid yarn which has first filaments (61) and second filaments (62), 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.

Description

technical field [0001] The present invention relates to an airbag and a method of manufacturing an airbag fabric for a vehicle occupant restraint system. Background technique [0002] When deployed, the airbag for a vehicle occupant restraint system expands three-dimensionally due to being filled, resulting in a shortened length of the textile tubular unit existing in a two-dimensional configuration. The inflatable airbag acts as a barrier between the vehicle occupant to be cushioned by it and some components of the motor vehicle interior. Usually, the textile tubular unit of the airbag itself does not have longitudinal or transverse rigidity, so it is difficult to form a very stable barrier. Especially when the side curtain airbag is deployed, the textile tubular unit shortens due to the three-dimensional deployment, which results in a barrier effect extending from the A-pillar to the C-pillar of the motor vehicle. Stable continuity from shoulder to roof rail. [0003] A...
