Abstract
An airbag includes an airbag body and an inner tube. The inner tube includes a gas upstream section located in an upstream region of an inflation gas stream fed from a gas generator and a gas outlet section that opens toward an inflatable region of the airbag body and feeds an inflation gas to the inflatable region. The gas outlet section includes a check valve section. The check valve section has a flexible and a generally tubular shape extending and opening toward the inflatable region due to pressure of an inflation gas so as to stream the inflation gas into the inflatable region. After the gas generator has finished discharging the inflation gas, the check valve section folds back toward the gas upstream section due to an internal pressure of the inflatable region and closes off the gas outlet section.
