The object is to enable inflation and deployment of an airbag (2) so that the passenger is protected more effectively by controlling inflation and deployment of the airbag. According to the present invention, in case of emergency such as a side crash of a vehicle, when gas from an inflator (4) flows quickly forward through a gas inlet passage (3) and reaches the closed end at the front end of the gas inlet passage (3), the internal pressure in the gas inlet passage (3) increases. Then, gas is blown from gas exhaust ports (3a, 3b) into the airbag (2) and the airbag (2) is inflated and deployed. At this moment, the gas exhaust ports (3a, 3b) open in the direction along the inner surface (6a) of the side portion (6) of the vehicle body, so that gas is blown from the gas exhaust ports (3a, 3b) in the same direction and the airbag (2) is inflated and deployed downwardly like a curtain along the inner surface (6a) of the side portion (6) of the vehicle body. Due to this inflation and deployment of the airbag (2), the airbag (2) is inflated and deployed quickly, smoothly and reliably in a relatively narrow space between the inner surface (6a) of the side portion (6) of the vehicle body and the passenger. <IMAGE> |
