Gas generator, particularly a mechanically triggerable gas generator
First Claim
1. A mechanically triggerable gas generator comprising a cylindrical casing in which a pyrotechnic charge, an ignition unit and a priming agent are arranged, wherein the casing has an inside diameter, said casing having two interconnected container spaces accessible from openings in opposite end faces of the casing, the ignition unit and the pyrotechnic charge being arranged in a first container space, and the priming agent being arranged in a second container space, and wherein the ignition unit comprises a holder means comprised of a ring and cover, the cover being joined to the ring said ring having an outside diameter and an inside diameter which is substantially constant throughout the thickness of the ring and said ring comprising a single solid element between said inside diameter and said outside diameter, said ring having substantially equal diameter openings at both ends, the cover separating the pyrotechnic charge from the ignition unit, and wherein an ignition charge is arranged in the ring and in contact with said priming agent.

Abstract
Gas generators having mechanical triggering have a cylindrical casing in which the various component parts are accommodated. The assembly of known gas generators is rather complex because of the different component parts. In the gas generator according to the invention the individual component parts are distributed in such a manner that essentially three units are formed, namely a priming agent, a pyrotechnic charge and an ignition unit comprising a holder means and an ignition charge. The priming agent is separated from the pyrotechnic charge by the ignition unit. The gas generator constructed in this way permits simple charging of the casing with the priming agent, the pyrotechnic charge and the ignition unit.
