SIDE AIRBAG APPARATUS
First Claim
1. A side airbag apparatus comprising:
- an airbag main body, which is configured to be deployed and inflated beside an occupant seated in a vehicle seat;
a gas generator, which supplies inflation gas to the airbag main body;
a lateral partition, which is arranged in the airbag main body and divides at least a part of an interior of the airbag main body into an upper inflation chamber and a lower inflation chamber, which is located below the upper inflation chamber;
a vertical partition, which is arranged in the airbag main body and has a communication portion, wherein the vertical partition divides the upper inflation chamber into an upper-rear inflation chamber, to which the inflation gas from the gas generator is supplied, and an upper-front inflation chamber, which is located forward of the upper-rear inflation chamber and to which the inflation gas is supplied via the communication portion; and
an inner tube, which is arranged in the airbag main body and regulates a flow of the inflation gas from the gas generator to direct the flow toward the upper-rear inflation chamber and the lower inflation chamber, wherein the inner tube includes, at a lower part, a check valve, which restricts a flow of the inflation gas from the lower inflation chamber to the upper-rear inflation chamber, whereinthe vertical partition includes two first fabric portions arranged in a width direction of the vehicle seat,the inner tube includes two second fabric portions arranged in the width direction, anda rear end of each first fabric portion is joined to an upper part of a front end of at least one of the second fabric portions by a first vertical joint portion.

Abstract
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.
