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 defined by at least one fold line and a plurality of flap portions, each flap portion having a base edge corresponding to a fold line and at least two side edges each extending outwardly from a base edge and ultimately converging to meet each other, the flap portions being folded at the fold line(s) and being Joined at corresponding side edges 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 withstand inflation pressures and impact when deployed and minimizes the packed volume of the cushion when stored.
An inflatable protective cushion comprising a sheet made of a woven material defined by four or fewer fold lines and a plurality of flap portions, each flap portion having a base edge corresponding to a fold line and at least two side edges each extending outwardly from the base edge and ultimately converging to meet each other, the flap portions being folded at the fold lines with each of the flap portions substantially converged to form an apex above the sheet and being joined at corresponding side edges to define an inflatable chamber, wherein the side edges are either substantially perpendicular or substantially parallel to the warp direction of the woven material.
An inflatable protective cushion comprising a single sheet having four or fewer fold lines and a plurality of flap portions, said sheet being, substantially in the shape of a square, each flap portion having a base edge corresponding to a fold line and at least two side edges each extending outwardly from the base edge and ultimately converging to meet each other, the flap portions being folded at the fold lines with each of the flap portions substantially converged to form an apex above the sheet and being joined at corresponding side edges to define an inflatable chamber.
An inflatable protective cushion comprising a single sheet having four or fewer fold lines and a plurality of flap portions, said sheet being substantially in the shape of a square, each flap portion having a base edge corresponding to a fold line and at least two side edges each extending outwardly from the base edge and ultimately converging to meet each other, the flap portions being folded at the fold lines with each of the flap portions substantially converged to form an apex above the sheet and being joined at corresponding side edges to define an inflatable chamber, wherein said side edges are configured at about said apex to form a means for mounting said sheet to an inflatable device.
An inflatable protective cushion comprising a sheet defined by four or fewer fold lines and a plurality of substantially triangular flap portions, each flap portion having a base edge corresponding to a fold line and at least two side edges extending outwardly from the base edge and ultimately converging to meet each other, the flap portions being joined at corresponding side edges to define an inflatable chamber.
