ABSTRACT:
Two embodiments of an air bag module and method of assembly are disclosed. One air bag module includes a flat support plate and a cover confining an air bag. The cover confines the air bag and has a plurality of resilient latch hooks spaced about its periphery which snap over the edges of the support plate and engage adjacent latch surfaces. A locking plate has a locking tab located adjacent each latch hook when assembled to the support plate to prevent deflection of the latch hooks and maintain the latch hooks in engagement with the latch surfaces. The inflator is later secured to the support plate by rivets which also secure the air bag and locking plate to the support plate. Another air bag module includes an air bag, an inflator, an open rectangular retainer mounting the air bag, and an open top and bottom container receiving the retainer and mounting the inflator, and a cover. A plurality of resilient latch hooks on the cover snap over the walls of the retainer and into indentations formed on the periphery of the bottom of the retainer. The retainer is inserted into the top of the container and the camming flanges guide the latch hooks into engagement with the walls of the container which confine the latch hooks against deflection, thus securing the cover against separation. The inflator is later inserted into the bottom opening of the container and secured by a closure.
