AI Technical Summary

Problems solved by technology

Tearing in the airbag can also be affected by the positioning of the jet groove relative to the airbag cavity
Additionally, airbag tears occur more frequently in borderline cases related to inflator hazards or to the ambient temperature to which the airbag is applied

Embodiment Construction

[0011] now refer to figure 1 , which schematically shows the airbag 2 viewed from the side by way of example. The position of the air bag 2 in the motor vehicle can be imagined as the top ( Figure 1a ) on the right side window of a moving car. The airbag 2 consists of a single-ply woven edge 4 shown shaded in the figure. "Front" and "rear" arranged tabs 6 are used to fix the airbag 2 in place (not shown) according to its position in the vehicle. exist Figure 1a The position of the airbag 2 in the vehicle 3 is roughly shown in . The airbag 2 is divided into a plurality of regions, namely a front seat region 8 and a rear seat region 9 , wherein in the event of a collision, the heads of the vehicle occupants would hit the side windows of the vehicle. This is why the airbag 2 needs to be inflated as early as possible in said regions 8 and 9 . To inflate the airbag, a gas lance 12 is inserted into the interior 7 of the airbag 2 , the gas lance 12 comprising injection openin...

Abstract

Disclosed is a method for weaving a single-pieced airbag (2) or air tube consisting of at least two layers on a mechanical loom, characterized in that weft yarns of different strengths are woven in at least one layer.

Description

technical field [0001] The invention relates to a method for weaving an integral airbag with at least two layers in a wide width. Background technique [0002] One piece woven (OPM) airbags are known and are used in the manufacture of automotive airbag systems. To inflate this integrally woven airbag, a gas lance is inserted into it. Practice has shown that tears occur in the region of the airbag where gas is injected into the bag from the gas lance. Gas lances often have a series of slits called gills, oriented roughly perpendicular to the gas flow, through which the gas is injected into the bag at several locations. The above-mentioned tearing in the airbag can occur, for example, due to differences in the design of the inflator, making it more or less hazardous, manifested by the appearance of depressions between and in the area of ​​the inflator jets . Tearing in the airbag can also be affected by the positioning of the jet channel relative to the airbag cavity. Add...
