Adjustably insulative construct
First Claim
1. A multi-layered composite construct having at least one inflatable and deflatable compartment therein, said construct comprising:
- at least two layers of a flexible, waterproof, air impermeable, optionally water-vapor-permeable material, the two layers forming at least one compartment therebetween, at least one additional layer of a porous insulating material disposed between said two layers and within said compartment, and a waterproof, airtight adhesive seal extending around the periphery of said compartment, wherein said at least two layers and said additional layer are adhesively bonded together about the periphery of said compartment and, optionally, at discrete locations within the periphery of said compartment, and wherein said adhesive penetrates the pores of the porous insulating material and bonds the at least two layers and the at least one additional layer together to form the adhesive seal, said porous additional insulating material layer being otherwise unattached to at least one of said at least two layers, said compartment having at least one sealable opening therein through which air may be injected into or removed from said compartment, as desired, thereby inflating or deflating said compartment to a desired volume.

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-penneable 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.

57. A sleeping bag having an access opening allowing entry by a user, said sleeping bag comprising:
-
an upper panel of at least two layers of a flexible, breathable, optionally air permeable material, at least one layer being waterproof, the two layers forming at least one compartment therebetween, the two layers having at least one additional layer of a porous insulating material disposed between said two layers and within said compartment, said upper panel being in registry with a lower panel of at least two layers of a flexible, breathable, optionally air-impermeable material, at least one layer being waterproof, the two layers forming at least one compartment therebetween, the two layers having at least one additional layer of a porous insulating material disposed between said two layers and within said compartment, said sleeping bag also having an optional outer-shell layer external to both upper and lower panels, wherein all layers of all panels are adhesively and sealingly bonded together about the periphery of said sleeping bag, except at said access opening thereof. - View Dependent Claims (58, 59, 60, 61, 62)
