Inflatable cushioning device

An inflatable cushioning device comprising:

• two layers of gas impermeable material each containing a plurality of spaced protrusions,
• said two layers sealed to each other at their peripheries and at various locations between said spaced protrusions to form an inflatable assembly, wherein said spaced protrusions extend away from a common central plane and are in fluid communication with each other,
• a port for inflation and deflation in said inflatable assembly for the attachment of an inflationary means,
• and two flat layers of similar size and shape connected to the tips of all said spaced protrusions on each side of said inflatable assembly,
• whereby said spaced protrusions are laterally stabilized by their connection to said two flat layers, are spaced to minimize the volume of air needed to fill said inflatable assembly, and support a load on the structure when inflated.

An inflatable cushioning device comprising:

• a layer of gas impermeable material containing a plurality of spaced protrusions,
• a flat layer of gas impermeable material of similar size and shape sealed to said layer at its periphery and at various locations between said spaced protrusions to form a first inflatable assembly, wherein said spaced protrusions extend away from said flat layer and are in fluid communication with each other,
• a similarly formed second inflatable assembly with similar spaced protrusions, wherein the tips of said similar spaced protrusions are connected to the tips of said spaced protrusions of said first inflatable assembly,
• and a port for inflation and deflation in said first inflatable assembly and said second inflatable assembly for the attachment of an inflationary means,
• whereby said spaced protrusions and said similar spaced protrusions are laterally stabilized by their connection to each other, are spaced to minimize the volume of air needed to fill said first inflatable assembly and said second inflatable assembly, and support a load on the structure when inflated.
