SIDE IMPACT AIRBAG APPARATUS

摘要

A side impact airbag apparatus includes an airbag, a gas generator, and a strap. The airbag is fixed to an automobile via an attaching portion in a rear lower portion. The gas generator supplies inflation gas to the airbag. The airbag includes a first section. The inflation gas deploys and inflates the airbag diagonally forward and upward from a part at which the airbag is fixed to the automobile. The front end of the strap is attached to the front end of the airbag. The rear end of the strap is attached to the fixed part of the airbag. The strap includes an upper strap portion, which is tensioned when the airbag is deployed and inflated, and a lower strap portion, which is located below the upper strap portion. The lower strap portion is tensioned with a tensile force greater than that of the upper strap portion.
