Abstract
An airbag includes a high pressure expansion chamber, a low pressure expansion chamber, and a communication passage, which connects the high pressure expansion chamber and the low pressure expansion chamber to each other. A gas supply port, which supplies inflation gas into the airbag, is located inside the low pressure expansion chamber to discharge the inflation gas toward the inside of the communication passage. The communication passage extends from the edge of a communication port, which connects the high pressure expansion chamber and the low pressure expansion chamber, toward the inside of the high pressure expansion chamber. At deployment and inflation of the airbag, the communication passage is located between a seam formed at the outer periphery of the base fabric sheet of the airbag and the gas supply port.
