1. An inflatable airbag for a motor vehicle, the inflatable airbag comprising:
a pair of superimposed layers of fabric interconnected by a peripheral seam extending around and defining the bounds of a single inflatable chamber between said layers; and
said single inflatable chamber having an inlet region comprising a fluid inlet connected to an inflator,
wherein the inflatable airbag includes first and second peripherally spaced-apart regions of said peripheral seam directly interconnected and secured to one another such that said inlet region is superimposed with at least one other region of the inflatable chamber to thereby induce an inflated shape to said chamber upon inflation of the airbag by a flow of gas from said inflator, and
said inflated shape includes said at least one other region of the inflatable chamber lying adjacent said inflator upon inflation of the airbag.
