<p>For gas generators that are to inflate airbags during a collision in a vehicle based auto- ignition system in the form of a temperature sensitive pyrotechnic composition for thermal fuse intended to produce spontaneous ignition at a well-defined auto-ignition temperature. This auto- ignition temperature must be lower than for the gas-generating mixture found in the gas generator. The pyrotechnic thermal fuse is characterized by the content of Guanylurea nitrate and/or Guanylurea dinitramide together with 3-nitro-l,2,4-triazol-5-one (NTO). Furthermore, it is mixed with an oxidizing agent plus a reducing agent in the form of a slag former. These components can be mixed in various compositions to produce an auto-ignition temperature between 150-180°C.</p>
