A lateral partition of a side airbag apparatus extends in a front-rear direction to divide the interior of an airbag into an upper inflation chamber and a lower inflation chamber. A vertical partition extends vertically and includes a communication portion. The vertical partition divides the upper inflation chamber into an upper-rear inflation chamber, to which inflation gas from a gas generator is supplied, and an upper-front inflation chamber, to which the inflation gas is supplied via the communication portion. An inner tube regulates the flow of the inflation gas to direct to the upper-rear inflation chamber and the lower inflation chamber. The rear ends of two first fabric portions of the vertical partition are joined to the upper parts of the front ends of two second fabric portions of the inner tube by a first vertical joint portion.

Side airbag apparatus

An airbag apparatus includes an airbag that has a first portion and a second portion. The airbag is folded such that the first portion approaches the second portion. The folded airbag has an elongated shape extending along a first direction. An inletis formed in the airbag. By receiving the supply of gas through the inlet, the folded airbagis inflated while being deployed in a second direction perpendicular to the first direction, such that the first portion moves away from the second portion. The inletis arranged in a part of the folded airbagthat is located in a trailing side in the second direction. A first attachment portionis provided in the same part of the folded airbag. A second attachment portionis provided in each of the ends of the folded airbag 5. The folded airbagis installed in a ceiling of a vehicleby means of the first attachment portionand the second attachment portions. When the airbagis being deployed and inflated, the second attachment portionsfunction to apply an outward tension along the first direction to the airbag
