An air bag assembly includes an inflator for discharging inflator gas. The inflator includes upper and lower longitudinal ends and an elongated longitudinal inflator axis. The inflator has a longitudinally elongated solid body portion and also has an outlet end portion located at the upper longitudinal end of the inflator atop the elongated solid body portion. The outlet end portion includes a plurality of discharge ports through which inflator gas is discharged. A base plate is connected to the inflator and extends radially outward therefrom. The base plate is positioned closer to the upper longitudinal end of the inflator than to the lower longitudinal end. The longitudinal inflator axis is generally perpendicular to the base plate to advantageously provide a T-shaped. An air bag is positioned above the base plate for deployment in an upwardly direction away from the base plate. This arrangement allows the outlet end portion of the inflator to distribute inflator gas evenly into the air bag and the longitudinal axis of the inflator to be oriented parallel to the direction of the inflating air bag.

Air bag assembly

An air bag module includes an axially elongated, extruded housing having a nautilus-shaped profile defined by a single continuously extending spiral-shaped wall. The spiral-shaped wall has first and second free ends and the spiral-shaped wall has a generally continually increasing radius of curvature from the first end to the second end. The housing preferably has a decreased radius portion for holding an inflator therein and an increased radius portion for holding an air bag therein. The decreased radius portion has a radius of curvature which is less than a radius of curvature of the increased radius portion.
