发明名称 Multi-stage gas generator for airbag of motor vehicle, has pressure chamber filled with gas, and passages openable by respective locking devices and provided between airbag and chamber, where airbag is filled with gas for long time period
摘要 #CMT# #/CMT# The generator (1) has a pressure chamber (6) that is filled with gas. Passages (2, 3) openable by respective locking devices (30, 40) are provided between an airbag and the pressure chamber, where the airbag is filled with the gas for a long time period. The locking devices include an igniter i.e. ignition tablet, that removes a barrier locking the passages during activation such that the gas flows from the pressure chamber into the airbag. Minimally flowed-through cross-section of the passage (2) is larger than a minimally flowed-through cross-section of the passage (3). #CMT# : #/CMT# An independent claim is also included for a method for filling an airbag of an airbag module with gas. #CMT#USE : #/CMT# Multi-stage gas generator for filling an airbag of an airbag module (claimed), which is utilized in a steering wheel, dashboard, A, B or C pillars, a door or a roof area of a motor vehicle for protecting a driver or a front seat passenger of the motor vehicle, with gas at time periods. #CMT#ADVANTAGE : #/CMT# The airbag is filled with the gas for the long time period, thus reducing danger of injury of a vehicle passenger. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic view of a gas generator of an airbag module. 1 : Gas generator 2, 3 : Passages 4 : Filter 6 : Pressure chamber 30, 40 : Locking devices.
