1. In an airbag for an automotive passenger airbag module formed from flexible material and having a mouth including first and second opposed edges, the improvement which comprises:
- each of said first and second opposed edges having incorporated therein a retainer rod;
first and second disc-shaped flanges carried by each of said retainer rods; and
a substantially planar stiffening rib carried by each of said retainer rods and extending radially outward therefrom longitudinally therealong intermediate said first and second flanges.

Abstract
A one-piece molded plastic retainer is employed to hold each of two opposed edges of an airbag mouth in engagement with a reaction canister. The retainer is sewn, or otherwise secured, in the airbag mouth and includes a rod carrying a pair of integral discs which snap-fit into rails in a diffuser plate. The rails are thereafter slid into channels in the reaction canister. The rod includes a stiffening rib to resist stresses imposed during assembly and during bag deployment.
