Abstract
A small, light-weight gas generator is provided for an air bag for protecting a passenger from impact by introducing a generated gas into an air bag. The gas generator includes a housing having a diffuser shell and a closure shell. The diffuser shell includes a round portion, a cylindrical portion extending concentrically from the round portion and an inner cylindrical portion extending about the center cylindrical portion and extending from the round portion. The closure shell includes an annular portion having a center hole for receiving the center cylindrical portion and a peripheral wall portion extending from the peripheral portion of the annular portion. This peripheral wall portion extends to the peripheral portion of the round portion of the diffuser. Electron beam welding may be used to bond the closure and diffuser shells together at the outer peripheral portion of the center cylindrical portion and the center hole; the inner cylindrical portion and the annular portion; and the peripheral portion of the round portion and the inner surface of the peripheral wall.
