ABSTRACT:
A multi-layered, composite, inflatable and deflatable article of manufacture is provided. The article includes at least two layers of a flexible, waterproof, air impermeable, optionally water-vapor-permeable material, the two layers forming at least one inflatable compartment therebetween. The two layers have at least one additional layer of a porous insulating material, e.g., batting, disposed between them within the compartment. The layers are all adhesively bonded together about the periphery of the compartment and, optionally, at discrete locations within the periphery of the compartment. The porous insulating layer is otherwise unattached to either of the waterproof layers, and preferably is not otherwise attached to either. The compartment has at least one sealable opening therein through which air may be injected into or removed from the compartment, as desired, to thereby inflate or deflate the compartment to a desired volume and to thereby control its insulative value. The construct of the invention is useful, inter alia, in garments, in air mattresses, in sleeping bags, or in a combination air mattress and sleeping bag, and in various bed covers.
