Abstract
An inflater of an air bag device is provided which includes a first combustor, providing an output having a peak value Ma and a second combustor, providing an output having a peak value Mb (wherein Mb<Ma). After ignition of the first combustor, the second combustor is ignited with a time lag. The igniting timing of the second combustor is set later than a time point at which the peak value of the sum of the outputs from the first and second combustors can be equalized to the peak value Ma of the output from the first combustor, and earlier-than a time point at which the combustion of the first combustor is finished. Thus, it is possible to prevent the sudden deployment of the air bag to moderate the shock applied to the occupant, while ensuring the smooth deployment of the air bag. The purpose of the inflater of an air bag device is to ensure that, in an air bag device including two gas generating devices which provide different outputs, the timing of the ignition of the two gas generating devices are appropriately controlled to moderate the shock received by an occupant upon deployment of the air bag.
