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 at least one communication port for communication between the first chamber and the second chamber. In an airbag uninflated state in which the inner panel and the rear panel are flatly deployed, at least part of the communication port is located within a range of 35 to 150 mm in radius from the center of a gas generator insertion port. Gas discharged from a gas discharge port is supplied to the second chamber via the communication port. Inflation of the second chamber, therefore, is accomplished in the early stage of the airbag deployment.
