Side impact air bag module

摘要

An air bag module (10b) includes an air bag, an inflator (40b), and a diffuser (100b) that receives the inflator. The diffuser (100b) has a central wall portion (122b) which is spaced radially outward from the inflator (40b) to define a diffuser chamber (128b). A first end portion (110b) of the diffuser (100b) extends radially inward from the central wall portion (122b) and blocks axial movement of the inflator (40b) in a first axial direction (138b). A second end portion (120b) of the diffuser (100b) has a radial portion (140b) extending radially inward from the central wall portion (122b) of the diffuser. The radial portion (140b) blocks radial movement of the second end portion (80b) of the inflator (40b) and blocks axial movement of the inflator in a second axial direction (158b) opposite to the first axial direction (138b). The module (10b) includes means, such as a plurality of bolts (130b), for supporting the module on a portion of a vehicle, such as a vehicle seat.
