Abstract
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.
