Abstract

A side airbag apparatus, which deploys an airbag between an occupant of a vehicle and a sidewall of said vehicle in order to protect said occupant in the event of side collision of said vehicle. This side airbag apparatus has a first airbag and a second airbag. The first airbag has a tube-like shape, and one end of the first airbag is fixed at a seat back of a seat of the vehicle and the other end of the first airbag is fixed at a seat cushion of the seat. The second airbag has a tube-like shape, and one end of the second airbag is fixed at the seat back and the other end of the second airbag is fixed at the seat cushion. In this side airbag apparatus, the position of one end of the second airbag is higher than the position of one end of the first airbag.

Claims

1. A side airbag apparatus, which deploys an airbag between an occupant of a vehicle and a sidewall of said vehicle in order to protect said occupant in the event of side collision of said vehicle, said side airbag apparatus comprising;
