In addition, the module (50) includes axially elongated second mounting members (120) each having an internal axial bore (126) therethrough for securely engaging the rearwardly extending portion (113) of the first mounting members (110) therein. The second mounting members (120) securely trap the air bag (80) and inflator flange (96) when the second mounting members (120) are fully engaged with the first mounting members (110). The second mounting members (120) are preferably adapted for mounting the module (50) to a support portion (30) of the vehicle.
