Abstract
An airbag device has an inflator to charge a small amount of gas into an airbag so as to inflate the airbag at a low internal pressure when an occupant is in proximity to the airbag device, and charges a large amount of gas into the airbag so as to inflate the airbag largely when the occupant is apart from the airbag device sufficiently. When an ignition signal is generated, a first igniter is fed currency first of all to generate a gas from a gas generating agent within a first compartment 6 and an airbag 1 begins to expand. When an occupant P is in proximity to the airbag device, the airbag 1 contacts with the occupant P immediately after starting to expand and a distance between a static pad 12 and an opposite pad 20 increases slowly. A static capacity detected in a static capacity detecting circuit 30 decreases slowly. When the static capacity exceeds a threshold value at a point when 10 millisecond have passed after an input of the ignition signal, a second igniter 9 is triggered.
