ABSTRACT:
A method of making a restraint cushion which when inflated forms a generally horizontally orientated lower compartment connected to a vertically orientated upper compartment comprising the steps of providing upper and lower sheets of woven material joined together along a rear edge and the side edges, forming a pleated section in the upper sheet, connecting the parts of the pleated section together, joining the pleated section to the lower sheet to form a wall separating the first compartment from the second compartment, and forming at least one opening between the compartments to allow fluid to flow from the lower compartment to the upper compartment.
