Abstract: A curtain airbag of a vehicle is provided adjacent to the roof of the vehicle in a folded state, is configured to have a shape that unfolds downward between an inner side surface of the vehicle and an occupant when the vehicle crashes, and includes an outer panel that proceeds toward the side surface of the vehicle and an inner panel that proceeds toward the occupant upon expansion. The curtain airbag further includes a head support part configured to have a shape in which an expansion thickness, which is defined by the outer panel and the inner panel in a portion that the head of the occupant contacts due to the car crash, gradually increases toward the front of the vehicle, so as to prevent the head of the occupant from rotating while moving toward the front of the vehicle. The curtain airbag may effectively stop the head of the occupant from rotating while moving toward the front of the vehicle during a vehicle crash.

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.
