Abstract
Abstract An air bag device for an automotive vehicle which comprises a reaction can disposed in a dashboard of the vehicle and a ring frame attached inside a portion of the reaction can. The air bag device also includes an air bag having a distal portion, a fixed portion disposed between the reaction can and the ring frame and a protruding portion which extends outside of the reaction can. The protruding portion has a stiffness greater than he distal portion of the air bag, whereby the distal portion of the air bag is substantially prevented from being disposed between the reaction can and the ring frame. A method for attaching the air bag to the reaction can is also disclosed.
