ABSTRACT:
An air bag, and a method of using the same, for indicating proper inflation and over-inflation of the air bag when the air bag is used within a void defined between adjacent cargo loads. In accordance with a first embodiment of the invention, a plurality of horizontally disposed, vertically spaced printed lines are provided upon only one side of the inflatable air bag and extend from a side edge portion of the air bag toward a central position of the side of the air bag for a predetermined distance. When the bag is inflated, as long as the lines are visible, the bag is properly inflated. If terminal end portions of the bag become visible, the air bag is over-inflated. In accordance with a second embodiment of the invention, a single vertical line is disposed upon only one side of the inflatable bag and is located a predetermined distance from the side edge portion of the bag which corresponds to the disposition of the terminal end portions of the horizontal lines of the first embodiment. When the bag is inflated, as long as the vertical line is not visible, the bag is properly inflated, whereas if the vertical line becomes visible, the bag is over-inflated.
