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 0.25×T milliseconds will be 0.25×P (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.

摘要： The invention provided a gas generator for an air bag having any of the following members. A deflecting member is provided to suppress discharge of a combustion product generated by a combustion of gas generating means, and is formed as a tube portion to be capable of shielding a gas discharge port formed at least on a circumferential wall of a housing from the inside of the housing. A coolant/filter means supporting member can position a coolant/filter means, prevent a short pass of an operating gas, and functions as a buffer member between the coolant/filter and the housing, and/or prevent a heat from being transferred to a diffuser shell, and comprises an annular portion arranged to face an end surface of the housing and a wall portion contacting with an inner periphery of the coolant/filter means. Further, in order to make it possible to securely support and fix the coolant means and prevent the short pass of the operating gas, an outer peripheral edge of an end portion thereof is adhered and/or supported to a bent portion or a step portion formed in an inner surface of an upper end surface and/or an inner surface of a lower end portion in the housing. The coolant/filter means is formed in a cylindrical shape obtained by laminating a wire mesh. The housing for the gas generator securely fixes an igniter included in an ignition means, is preferably used at a time of manufacturing a gas generator having a restricted overall height, and has an opening portion for inserting and fixing the igniter or an igniter supporting member. The opening portion is provided with a connecting portion for fixing the inserted igniter or igniter supporting member, and the connecting portion is provided in inner side of the housing rather than the end surface having the opening portion.
