Abstract
A lightweight can assembly for housing and protecting the gas generator and inflatable bag of a passenger side restraint system includes a tether in the bag flush with the mouth of the can and at its center which retains the spreading forces at the mouth of the can upon bag deployment. This allows for a lighter section at the mouth of the can and eliminates the need for flanges along the sides of the can, which flanges would undesirably increase the envelope.
