Gas generating composition, use thereof in a gas generator and use of a basic mixed metal nitrate

Abstract

A gas generating composition for a safety device in a vehicle comprises an oxidant which comprises a basic mixed metal nitrate, wherein the basic mixed metal nitrate is based on a basic metal nitrate in which the metal of the basic metal nitrate is partly replaced with at least one further element.The disclosure further states the use of such gas generating composition and of such basic mixed metal nitrate.

1 . A gas generating composition for a safety device, specifically in a vehicle, with an oxidant comprising a basic mixed metal nitrate, wherein the basic mixed metal nitrate is based on a basic metal nitrate in which the metal of the basic metal nitrate is partly replaced with at least one further element. 
     
     
         2 . The gas generating composition according to  claim 1 , wherein the basic metal nitrate is a basic transition metal nitrate, preferably basic copper nitrate. 
     
     
         3 . The gas generating composition according to  claim 1 , wherein the at least one further element is selected from a group consisting of alkaline earth metals, transition metals, aluminum and boron. 
     
     
         4 . The gas generating composition according to  claim 1 , characterized in that wherein the at least one further element comprises or is zinc. 
     
     
         5 . The gas generating composition according to  claim 1 , wherein, in the basic mixed metal nitrate, 10 mole percent or more of the metal in the basic metal nitrate are replaced with the at least one further element. 
     
     
         6 . The gas generating composition according to  claim 1 , wherein, in the basic mixed metal nitrate, 95 mole percent or less of the metal in the basic metal nitrate are replaced with the at least one further element. 
     
     
         7 . The gas generating composition according to  claim 1 , wherein a crystal structure of the basic mixed metal nitrate corresponds to a crystal structure of the basic metal nitrate. 
     
     
         8 . The gas generating composition according to  claim 1 , wherein the at least one further element is arranged to be distributed stochastically or periodically in the basic mixed metal nitrate. 
     
     
         9 . (canceled) 
     
     
         10 . (canceled) 
     
     
         11 . The gas generating composition according to  claim 1 , wherein, in the basic mixed metal nitrate, 40 mole percent or more of the metal in the basic metal nitrate are replaced with the at least one further element. 
     
     
         12 . The gas generating composition according to  claim 1 , wherein, in the basic mixed metal nitrate, 80 mole percent or less of the metal in the basic metal nitrate are replaced with the at least one further element.
