Abstract
The present invention provides an end-face-burning gas generator having a simple internal structure for easy manufacture, in which the amount of generated gas can be varied during gas discharge. The present invention provides a gas generator including a housing provided with a gas discharge port, an ignition device provided within the housing, a gas generating agent formed in a lump form and provided within the housing such that the gas generating agent is ignited and burnt, by the ignition device, in an end surface thereof, the gas generating agent having a form or a structure such that a combustion surface area thereof changes as the gas generating agent is being burned.
Claims21
A gas generator, comprising:
- a housing provided with a gas discharge port;
- an ignition device provided within the housing;
- a gas generating agent formed in a lump form and provided within the housing for generating a gas by burning, the gas generating agent including a combustion starting end surface that start a combustion thereof by the ignition device and having a form or a structure such that a combustion surface area varies as the gas generating agent is being burned;
- and
- combustion-restricting means provided on all surfaces of the gas generating agent other than the combustion starting end surface, the combustion -restricting means restricting the combustion of the all surfaces other than the combustion starting end surface.
A gas generator, comprising:
- a housing provided with a gas discharge port;
- an ignition device provided within the housing;
- a gas generating agent formed in a lump form and provided within the housing such that the gas generating agent is ignited and burnt, by the ignition device, in an end surface thereof, the gas generating agent having a form or a structure such that a combustion surface area thereof changes as the gas generating agent is being burned.
A method of manufacturing a gas generator including therein a gas generating agent that generates a gas when burned and an ignition device for igniting and burning the gas generating agent in the interior of a housing having a gas discharge port, comprising the steps of:
- charging a gas generating agent chamber provided within the housing with a fluid-state gas generating agent;
- and
- curing the fluid-state gas generating agent to form a lump-form gas generating agent having a combustion starting end surface and a form or a structure such that a combustion surface area thereof varies as the gas generating agent is burned.
