Abstract

An air bag safety system comprising an air bag cushion and a cylindrical-shaped inflator assembly connected to the air bag cushion. The inflator assembly is figured to rapidly fill the air bag cushion upon being actuated. The inflator assembly is attached to a base plate by an attachment assembly configured to attach the inflator assembly to the base plate without either applying force to the inflator assembly so as to deform the attachment assembly or applying heat to the inflator assembly. The attachment assembly comprises a tie strip and a retention mechanism configured to lock the tie strip in place to hold the inflator assembly on the base plate. The air bag safety system also includes a plurality of resilient mounting hooks configured to cooperate with either a frame member within the vehicle occupant compartment or an attachment piece mounted to the frame member, such that air bag safety system can be snapped in place. The air bag safety system also includes a heat shield attached to the base plate to protect the interior surface of said air bag cushion from the gases used to rapidly inflate the air brag cushion. A method of assembling the air bag safety system is also provided.
