An inflatable, self-supporting shelter particularly suited for survival use in remote, rugged terrain and evacuating injured victims includes inflatable floor and side panels and two opposing multi-layered, noninflatable end panels which cooperate to form an enclosed shelter. The floor and side panels each include an inner wall, outer wall and plurality of parallel, longitudinally extending strips therebetween. The strips, which are connected to both the inner and outer walls, have an “I”shaped cross section and serve to divide the air space between the walls into a series of pneumatically interconnected cells and to rigidify the shelter when it is inflated. In one embodiment, the shelter is provided with pole receiving means to facilitate transporting the shelter as a litter, and fastening means securing the side panels and end panels to one another such that the shelter can be “opened up”to provide quick and easy access to the victim.

A self-supporting, inflatable survival shelter comprising: an inflatable floor portion of air impermeable material; a pair of inflatable side portions of air impermeable material, said floor and side portions having a substantially triangular configuration when inflated; a pair of opposed, quilted end portions of non-inflatable insulation material; fastening means cooperable with one of said end portions and said side portions to permit opening and closing of said one end portion; said floor and side portions each including: an outer wall; an inner wall; and a plurality of parallel, substantially I-shaped strips connected to said inner and outer walls, and extending substantially the entire length or width of said inner and outer walls, such that said inner and outer walls, when inflated, are spaced from one another and divided into a plurality of air-filled cells; the shelter further including longitudinally extending strips connecting adjacent abutting cells of said floor and side portions, each said strip and associated cells cooperating to form a longitudinal insulating air pocket adjacent an interface between said abutting cells when inflated.
