1. An inflatable airbag assembly for a passenger vehicle, said airbag assembly comprising:
- an airbag having a plurality of substantially isolated cells;
a delivery tube having a plurality of outlet orifices for supplying an inflation gas to the plurality of substantially isolated cells;
an upper restraint for the delivery tube;
a series of discrete stitchings located between the substantially isolated cells, the series of discrete stitchings each forming a lower restraint for the delivery tube; and
wherein, upon inflation of the plurality of substantially isolated cells with the inflation gas, flow of gas between each of the plurality of substantially isolated cells is restricted by the series of discrete stitchings and the upper restraint.

Abstract
An inflatable side curtain airbag for a passenger vehicle is provided. The airbag incorporates a new diode design that restricts gas flow, creating a plurality of substantially isolated cells. A delivery tube delivers gas to the cells through a plurality of outlet orifices that open to the cells. Upon inflation of the cells with a gas, flow of gas between each of the plurality of substantially isolated cells is restricted during occupant loading.
