Embodiment Construction

[0053] Figure 1a with 1b An airbag 10 according to the invention is shown, which in the embodiment shown is designed as a head-side airbag 10 .

[0054] The airbag 10 comprises at least two opposing fabric layers 12 and 14 forming at least one inner wall 13 and one outer wall 15 of the airbag 10 . The airbag 10 is produced in one piece by a multilayer weaving process, wherein the fabric layers 12 and 14 are interwoven with one another at least in the edge region 16 . Figure 1b The double dashed lines in , here, indicate the boundary of the edge region 16 from which the textile plies 12 and 14 are not interwoven with each other to form the airbag interior 50 .

[0055] Figure 1a The airbag 10 shown also includes subdivided sections 54 in which the two textile plies 12 and 14 are also interwoven with one another, so that the airbag 10 is not inflated in this region.

[0056] The airbag 10 shown also includes a plurality of airbag fastening sections 82 which are provided for...

Abstract

The invention relates to an airbag (10), in particular a head-side airbag (10) or a head-chest-side airbag, comprising at least two opposite fabric layers (12, 14) which form at least an inner wall (13) and an outer wall (15) of the airbag (10), the airbag (10) being produced in one piece by means of a multi-layer weaving process, in which the fabric layers (12, 14) are interwoven with one another at least in edge regions (16), a gas generator receptacle (18) for an external gas generator (20) is provided in one of the two fabric layers (12, 14). The invention further relates to an airbag module (8) having an airbag (10) according to the invention and to a method for producing a one-piece woven airbag (10) and to a method for producing an airbag module (8).

Description

technical field [0001] The invention relates to an airbag according to the preamble of claim 1 , an airbag module according to the preamble of claim 11 , a method for producing a one-piece woven airbag according to the preamble of claim 12 and the preamble of claim 15 Part of the method for manufacturing an airbag module. Background technique [0002] Airbag modules with airbags woven in one piece in a multilayer weaving process (so-called one-piece woven or OPW airbags) are known from the prior art, which are used, for example, in head side airbags arranged in the region of the roof edge Or head-thorax side airbags (so-called Curtain-Airbags or curtain-type airbags). [0003] In this type of airbag module, the tubular gas generator is pushed at least partially into the insufflation opening of the airbag, and the airbag is fastened around the housing of the gas generator. One or more fastening bolts, and / or one or more collars, and / or fastening straps / fastening fabrics pro...
