Abstract: In order to sufficiently absorb the impact applied to a container from upward, the top surface of the container is made of a sheet separately from the other portion. Lugs projected from the top surface are welded to the side surfaces of the container, while lugs-projected from the side surfaces are welded to the underside of the top surface. When an impact is applied to the container from upward, deformation of the container easily begins from the side surfaces, so that a large amount of impact energy is absorbed.

Abstract: An air bag device for a vehicular passenger is formed of a box-shaped container having an open front face; an air bag confined in a folded shape in the container; an inflator attached to the container; and a lid covering the front face of the container. Further, a stress concentration portion is formed in the container for starting the buckling deformation of the container when an impact is applied to the container from the front.

Abstract: An air bag device for a vehicular passenger, includes: a box-shaped container having an open front face; an air bag confined in a folded shape in the container; an inflator attached to the container; a lid covering the front face of the container; a lid mounting bracket disposed along the upper face of the container; and a backup plate forming the lid and having its upper face extended to the back of the lid to provide a lid mounting portion fixed on the lid mounting bracket. Further, a load transmitting member is interposed between the lid mounting bracket and the upper face of the container for transmitting a load, which is applied to the lid mounting bracket toward the container, to the container.
