Abstract: An airbag system of an automotive vehicle, wherein an airbag expanded and deployed to position in front of the vehicle occupant in the event of eccentric, left/right collision is added by a control member for being rotated on an inflator by inertia and for restraining flow direction of gas infused into the airbag, thereby cushioning and protecting the occupant effectively against injury-causing impact from eccentric collision, and the inflator is disposed thereon with a hitching bracket so provided to avoid an interference from the control member and having a hitching unit rotatively supporting a central part of an integral tether, both tip ends of which are separably fixed to an inner surface of the airbag.
