Abstract
An airbag includes an inner panel for partitioning an interior of the airbag into a first chamber and a second chamber surrounding the first chamber. The inner panel has communication ports for communication between the first chamber and the second chamber. In an airbag inflated state, at least some of the communication ports are located in a section of the inner panel that is, with respect to a steering wheel, on a side of the steering wheel opposite from the passenger position. Gas discharged from gas discharge ports is supplied to the second chamber via the communication ports. Inflation of the second chamber, therefore, is accomplished in the early stage of the airbag deployment.
