(57) [Summary] In an early stage of operation, an occupant is operated with as little impact as possible, and then the occupant is reliably protected by rapidly increasing the gas pressure. Provided is a gas generator for an airbag having a simple structure. A single ignition means operated by impact, a gas generating agent ignited by the ignition means and burning to generate a combustion gas, and a cooling and / or cooling of the combustion gas are provided in a housing having a gas discharge port. Or, a gas generator for an airbag containing and containing a filter means for collecting combustion residues, the operation performance of which is such that a desired tank maximum pressure in a tank combustion test is P (kPa), When the time from the start of the rise of the tank pressure to the arrival of the tank maximum pressure P (kPa) is T milliseconds, the tank pressure after 0.25 x T milliseconds is 0.25 x A gas generator for an airbag which is adjusted so as to be P (kPa) or less. |
