A restraint system includes a curtain airbag having an outboard layer 36 and an inboard layer 38, an extension layer 40 fixed to the inboard layer, and an inflator (42, see fig.9). The outboard and inboard layers define a first inflation chamber (44) therebetween. The extension layer defines a second inflation chamber (46) between the extension layer and the inboard layer. The inflator is in communication with the first and second inflation chambers; however, the first and second inflation chambers are fluidly isolated from each other. The inflator may comprise separate conduits (80, 78) to feed first and second inflation chambers. The inflator may include two separate charges and may be of different size. The restrain system may also comprise a diffuser (96, see fig.6) to distribute an inflation medium at different rates. The airbag may comprise a tether or a depression.
