Airbag, airbag system and vehicle

摘要

An airbag is inflated with gas ejected from an inflator disposed at a base-end thereof in a direction that a front end of the airbag moves away from the base-end of the airbag. The airbag includes a left half airbag to be inflated on a front left side of an occupant and a right half airbag to be inflated on a front right side of the occupant. The airbag is formed of an inner panel extending from a front end of the right half airbag to a front end of the left half airbag; a right outer panel forming an outer surface of the right half airbag; a left outer panel forming an outer surface of the left half airbag; and a base-end panel forming a base-end chamber. The gas from the inflator is supplied into the left and right half airbags through the base-end chamber.
