ABSTRACT:
The present invention is a small, light-weight gas generator for a passenger air bag. The gas generator includes a housing having a diffuser shell and a closure shell. The diffuser shell includes a round portion, a center cylindrical portion extending concentrically from inside a peripheral portion of the round portion, and an inner cylindrical portion. The center cylindrical portion is disposed at the center of the round portion for storing therein a squib-enhancer. The inner cylindrical portion is disposed outside the center cylindrical portion to provide a combustion chamber. The closure shell includes an annular portion equipped with a center hole for receiving the center cylindrical portion, and a peripheral wall portion extending from the peripheral portion of the annular portion to the peripheral portion of the round portion of the diffuser shell. This peripheral wall portion defines a coolant-filter chamber and includes a gas discharge port and a flange portion extending in a radial direction. Welding bonds the closure and diffuser shells together at the outer peripheral portion of the center cylindrical portion and the peripheral portion of the center hole; at the tip of the inner cylindrical portion and the region of the annular portion coming into contact with the tip; and at the peripheral portion of the round portion and the tip portion of the peripheral wall portion.
