Embodiment Construction

[0087] Figure 1a A longitudinal sectional view of a tubular gas generator 100 is shown, wherein the installation of the fuel cage 10 according to the invention and the filler element 50 according to the invention is to be shown. The tubular gas generator 100 includes a high-pressure gas container 30 constituting a casing 31 of the tubular gas generator 100 . The high-pressure gas container 30 is substantially tubular in shape and contains prestressed high-pressure gas or a high-pressure gas mixture having a pressure value of 300 bar to 800 bar, especially 550 bar.

[0088] The recess 32 of the housing 31 divides the high-pressure gas container 30 into a first section 33 in which the igniter unit 20 , the fuel cage 10 and the filler element 50 are arranged. The second section 34 of the high-pressure gas container 30 is designed substantially free of inlays and serves to accommodate the majority of the prestressed high-pressure gas. The high-pressure gas is present both in th...

Abstract

The invention relates to a propellant cage (10) for a tubular gas generator (100), especially for the tubular gas generator (100) of an airbag module, for forming a propellant chamber (14) and a flowpassage (15) of the tubular inflator (100). In accordance with the invention, the propellant cage (10) is in the form of a propellant cage spiral spring (11) having a gas inlet-side end (12) and a gasoutlet-side end (13), the gas inlet-side end (12) having a smaller cross-section than the gas outlet-side end (13).

Description

technical field [0001] The invention relates to a fuel cage according to the preamble of claim 1 for a tubular gas generator, in particular for a tubular gas generator of an airbag module. Furthermore, the invention relates to a filler element according to the preamble of claim 3 for a tubular gas generator, in particular for a tubular gas generator of an airbag module. Furthermore, the invention relates to a tubular gas generator for an airbag module. Furthermore, the invention relates to an airbag module having such a tubular gas generator. Furthermore, the invention shows a vehicle safety system, a method for operating a tubular gas generator and a method for producing a tubular gas generator. Background technique [0002] A fuel cage having the features of the preamble of claim 1 is known, for example, from EP 2 471 692 B1. [0003] The fuel cage of a gas generator generally fulfills multiple functions. In the installed state, the fuel cage delimits in particular a f...
