Definitions
- the present invention relates to a gas generator suitable for inflating an airbag or the like.
- the housing is a metal housing formed by an initiator shell and a closure shell.
- a combustion chamber is formed in the housing.
- the gas generating agent is loaded in the combustion chamber, and generates a high-temperature gas by combustion.
- a plurality of gas discharge holes are formed in the housing for discharging gas generated in the combustion chamber.
- the length of the gas generating agent thus obtained is usually in the range of 1.5 mm or more and 8 mm or less, preferably in the range of 1.5 mm or more and 7 mm or less, and more preferably in the range of 2 mm or more and 6.5 mm or less. It is in the following range.
- the gas generating agent is preferably a non-azide-based gas generating agent
- the raw materials used are those that are less harmful to humans.
- the calorific value per generated gas mole can be suppressed, and the size and weight of the gas generator can be reduced.
