ABSTRACT:
The present invention provides a gas generator (10) that includes a housing (12) formed from coupling a cap (14) and a base (16) in nested relationship. At least one attachment member (20) is preferably formed symmetrically about and integral to a peripheral flange (18) of the cap (14). The contour of a peripheral edge (60) formed from recessed and protruding portions provides interlocking communication between the cap (14) and the base (16). A plurality of hook members (36) is symmetrically formed about the peripheral edge (38) of the base (16). Each hook member (36) corresponds to a respective protruding portion (30) of the cap (14). An arcuate groove (40) is formed by an inner wall (42) of each respective hook member (36). The groove (40) is preferably tapered whereby the arcuate length of the groove or the inner wall (42) is greater at the first end (44) than at the second end (46). As a result, the base (16) when rotatably fixed to the cap (14) provides an interference fit at the hook/cap periphery interface.
