Airbag gas generator and an airbag apparatus

摘要

An airbag gas generator with a simple construction, which operates to apply as small an impact as possible to the passenger during the initial stage of its operation and thereafter rapidly increase the gas pressure to reliably protect the passenger.The airbag gas generator which includes in the housing with gas discharge ports a single ignition means activated by impacts, a gas generating agent ignited and burned by the ignition means to produce a combustion gas, and a filter means to cool the combustion gas and/or arrest combustion residue. The operation performance of the gas generator is adjusted such that the tank pressure measured at 0.25xT milliseconds will be 0.25xP (kPa) or less where a desired tank maximum pressure in the tank combustion test is P (kPa) and a period of time from the start of rising of the tank pressure to the time when the maximum pressure P (kPa) is reached is T milliseconds.
