GAS GENERATOR

摘要

A gas generator capable of maintaining a non-critical combustion speed and carrying out a very stable combustion of a gas even when the gas in use has a combustion speed influenced greatly by an ambient temperature just as a non-azide gas generating agent. Concretely speaking, this is a gas generator having a gas generating agent stored in an inner part thereof, a bursting plate and an opening with the bursting plate contacts being provided in the mentioned order in the direction in which a gas from the gas generating agent passes, characterized in that a thickness t of the bursting plate and a circle equivalent diameter D of the opening are set so that following equation is satisfied, wherein the tensile strength of the bursting plate is represented by A (kgf/cm<2>), the thickness thereof t (cm), and the circle equivalent diameter of the opening which the bursting plate contacts D (cm). This invention also provides a gas generator in which the whole or a part of the bursting plate is formed out of a nonmetallic material having a melting point of not lower than 500 DEG C.
