The present invention provides a coolant for an air bag inflator in which unevenness in density in the axial direction is reduced even though the coolant is compressed in its axial direction. The coolant is a molded product made of wire rods and compressed in its axial direction. An absolute value of a difference between a radial pressure loss of the axially upper half portion of the coolant and a radial pressure loss of the axially lower half portion of the coolant is 10 mm HO or less at a flow rate of 250 liters/minute under the atmosphere of 20&#xb0; C.

Coolant for air-bag gas generator and production method therefor

An inflator comprises a cylindrical inflator housing elongated in an axial direction and containing a gas generating material for inflating an air bag, and an activation assembly for generating an activation gas for activating the gas generating material. A cylindrical diffuser assembly is provided in an axial end of the inflator housing. The diffuser assembly has an end surface, and also has a plurality of outlet holes in a peripheral wall surface thereof. A through-hole is formed in the end surface of the diffuser assembly, and a stud bolt for fixing the inflator is inserted into the through-hole. The stud bolt is fixed by a flange portion provided on an end portion thereof.

Inflator

A hybrid inflator having a structure permitting easy and reliable mounting to an airbag module, facilitating welding during manufacture, and improving in gas sealability and reduced in weight, is provided. The hybrid inflator is for use in an inflation type safety system for a motor vehicle equipped with an airbag, and includes an inflator housing, pressurized gas contained at least in the inflator housing, a gas generator housing connected to the inflator housing and provided with at least one gas generator outlet, a gas generating agent contained in the gas generator housing and ignited by an initiator, and an inflator operation assembly containing the initiator for operating the inflator. The inflator operation assembly comprises a boss welded to an end portion of the inflator housing to hermetically seal the housing, and the boss has an edge of flange shape to be mounted to an airbag module.
