Gas generator for an airbag
First Claim
1. A gas generator for an airbag comprising:
- a) a gas-generating material based upon an azide;
b) an ignition means operatively connected to the gas-generating material;
c) at least one layer of a mesh fabric disposed about the gas-generating material and ignition means;
d) a non-metallic non-fragmenting high-pressure component disposed about said gas-generating material, said ignition means and said mesh fabric, said high-pressure component comprising an electric high-pressure bag constituted from a pressure-resistant and tear-resistant fabric;
e) at least one rupturing location incorporated into the high-pressure component;
said at least one rupturing location being adapted to rupture upon reaching a predetermined internal gas pressure; and
f) a low-pressure bag collectively disposed about said gas-generating material, said ignition means, said mesh fabric, said high-pressure component and said at least one rupturing location, and gas flowing into said bag through said at least one rupturing location to fill the low pressure bag with gas.

Abstract
A gas generator for an airbag, including a gas-generating material which is based on an azide, an ignition device and at least a single ply or layer consisting of a sieve-netting or mesh fabric. The gas-generating material or compound together with the ignition device are arranged in either a gas-tight and heat-resistant, flexible or elastic, non-fragmenting high-pressure component with gas pressure-dependently opening rupturing or breaking locations, such as a high-pressure bag or pouch constituted from a pressure-and tear-resistant fabric, or from a high-pressure container, and wherein the rupturing or breaking locations of the high-pressure component communicate with a low-pressure bag or pouch constituted from a tear-resistant fabric with outflow or discharge apertures or windows.
