Problems solved by technology

This results in the airbag collapsing due to outflow of airbag gas when impacting the occupant and hitting the occupant relatively softly
However, this has the disadvantage
On the one hand, when using air-permeable fabrics with a defined air permeability, fluctuations in the absolute air permeability can occur, which can have a negative effect on the escape of gas during impact of the airbag and thus on the impact strength
On the other hand, when the airbag is deflated, combustion residues in the airbag inflator can reach the passenger seat through the airbag vent hole, which can also cause injury

Embodiment Construction

[0015] exist figure 1 A greatly simplified cross-section of an airbag fabric seen in the warp direction is shown in . Here, the warp 2 is shown as a small circle in the drawing plane, and simultaneously as a cross-sectional diagram of the warp 2, and the wefts 4 and 4' (shown in plain weave for simplicity here) are drawn from the left in the drawing plane. Stretch right and wrap warp 2 with open. (exist figure 1 Middle) A film 6 is applied on the upper surface of the fabric shown. The film is applied to the fabric, for example by thermal bonding or other usual bonding material. exist figure 1 The arrangement of the weft threads 4 and 4' and the warp threads 2 shown in , corresponds to the state of the airbag fabric, as it leaves the weaving machine and after gluing. Arrow 8 shows the amount of air desired and able to pass through the fabric or the air permeability of the fabric. That is to say, the air must reach between the threads or between the intersections of the th...

Abstract

The invention relates to a woven surface form used in a passenger anti-forward system, characterized in that it contains plastically deformable threads that allow the fabric surface to be increased along at least one surface material direction when loaded, Furthermore, the woven sheet-like body has an especially elastic coating.

Description

technical field [0001] The invention relates to a woven planar body used in an anti-rush system for passengers and a manufacturing method thereof. Background technique [0002] In the airbag systems currently used, airbags or airbags are used which in principle have the potential danger that a passenger who hits an inflated airbag is bounced back by the high pressure present in the airbag (rubber-ball effect). This could cause serious injury to passengers. This problem is currently solved, for example, by providing ventilation openings or valves on the side of the airbag facing away from the impact, or by providing air-permeable fabrics with a defined air permeability in these regions. This results in the airbag collapsing due to outflow of airbag gas when impacting the occupant, and impacting the occupant relatively softly. However, this has disadvantages. On the one hand, when using air-permeable fabrics with a defined air permeability, fluctuations in the absolute air ...
