Abstract
An inflation portion of an airbag main body is divided into a first inflation chamber, a second inflation chamber in front of and adjacent to the first inflation chamber with a vertical partition in between, and a third inflation chamber below the first inflation chamber with a lateral partition in between. The vertical partition has a pressure regulator valve. Before the first inflation chamber restrains an occupant, the pressure regulator valve restricts flow of inflation gas from the first inflation chamber to the second inflation chamber. When the first inflation chamber restrains the occupant, the pressure regulator valve opens in response to a change in the tensed state of the vertical partition due to the applied external force generated by the restraint, thereby cancelling the restraint. The lateral partition has a check valve, which restricts flow of inflation gas from the third inflation chamber to the first inflation chamber.
