Abstract
A vehicle air bag module comprises a container, a folded air bag disposed substantially inside the container, and an inflator coupled to the container. The container comprises a reaction device and a cover fastened to the reaction device. A retainer frame is located outside the container. A segment of the air bag material is disposed between the cover and the reaction device, and is connected to the retainer frame. The segment of the air bag is captured between the cover and the reaction device as the cover and reaction device are fastened together. Thus, the same structure which fastens the cover to the reaction device also fastens the air bag to the container. Since the retainer is disposed outside of the container, the volume of the container is relatively small, and the module is relatively compact. Also, the retainer is preferably a continuous frame which is drawn into force transmitting relation with the reaction device during deployment of the air bag, to anchor the air bag securely to the reaction device during deployment of the air bag.
