Abstract: An airbag that prevents heavy interference with the head of an occupant during expansion and deployment even when the occupant is not seated in a vehicle seat in a regular position is configured to be positioned to the sides of the center in the left-right direction of a vehicle seat and has a pair of chambers physically coupled by a coupling section that deploy forward of the occupant when expansion and deployment are complete. The pair of chambers are independent during expansion and deployment and expand and deploy frontward from both the left and right sides of the vehicle seat, having side protecting chambers that cover at least the side sections of the occupant. The side protecting chambers are coupled by coupling sections positioned to the sides of the center in the left-right direction of the vehicle seat, and the coupling section is thinner than the side protecting chambers at least during initial expansion and deployment.
