Abstract

Abstract An airbag apparatus for a small size vehicle that includes an airbag, for constraining a driver on a seat from forward motion through an inflation expansion, that reduces the number of parts and achieves miniaturization of the apparatus while constraining the driver on the seat. The airbag includes a main bag portion and an auxiliary bag portion communicating with the inside of the main bag portion through a connecting hole. The auxiliary bag portion is inflated and expanded with gas exhausted from the main bag portion through the connecting hole.
