Abstract
An air-bag for a motor vehicle is formed from first and second superposed layers of fabric, each woven from a plurality of yarns. The layers of fabric are connected to each other at least partially through interweaving of the yarns of the two layers with each other. The air-bag includes at least one inflatable region, in which the two layers of fabric are substantially not connected to each other, and at least one non-inflatable region. There is a first number of crossing points of yarns that form the one layer of fabric, and there is a second number of connections between the two layers, wherein at each connection a yarn of the layer of fabric extends across to the other layer and passes over the far side of the a yarn of the other layer, and wherein the second number is no more than 0.0033 times the first number.
