Inflatable cushioning device

摘要

An inflatable cushioning device is provided that is comprised of three layers of flexible gas-impermeable material. One of such layers of material is formed with spaced protrusions throughout its length and width. This layer, when sealed to a flat layer of similar shape along its periphery and at various locations between the protrusions, forms an inflatable assembly. The ends or tips of the spaced protrusions are connected to another flat layer of similar size and shape for structural support. When inflated the protrusions act as the main structure for supporting a load upon the inflatable device. The protrusions are spaced close enough to provide ample load support but far enough apart to minimize the overall volume of air needed to inflate the device to full size.
