Airbag inflator for vehicle occupant restraint apparatus |
摘要 |
To achieve a reduced inflation rate of an airbag in a vehicle occupant restraint apparatus, an airbag inflator is provided with a seal ring acting, in response to initial pressurization by a pyrotechnic initiator, to open injection ports, such that liquid propellant may be regeneratively pumped by a piston from a reservoir into a combustion chamber for combustion. The resulting combustion gases flow through a series of swirl chambers to increase residence time and through a plenum chamber where the combustion gases are cooled. The combustion gases exit the plenum chamber as an airbag inflation gas.
