Abstract

An apparatus and method for making a low cost, self-venting, inflatable protective cushion of simple and structurally efficient design with a shape and construction that optimizes the cushion's ability to withstand inflation pressures and impact when deployed which includes a sheet (20) of material woven of less than 420 denier yarn defined by at least one fold line (22) and a plurality of flap portions (23), each flap portion having a base edge (24) corresponding to a fold line (22) and at least two side edges (25) each extending outwardly from the base edge (24) and ultimately converging to meet each other, the flap portions (23) being folded at the fold lines (22) and being joined at corresponding side edges (25) to define an inflatable chamber. The inflatable protective cushion and method for making same may further include a lightweight, low permeability, fabric that optimizes the cushion's ability to whithstand inflation pressures and impact when deployed and minimizes the packed volume of the cushion when stored.
