Sleeping pad with dual coated bottom sheet and central layer

An inflatable sleeping pad comprising:

• an inflatable pad having a top layer and a bottom layer, said top and bottom layers disposed parallel to one another and having a length and a width, wherein said top and bottom layers each include an interior facing surface, and wherein each of said interior facing surfaces of said top and bottom layers include at least a plurality of heat weldable regions;
• at least one middle layer constructed of a thermal energy reflective material having a length and a width and disposed parallel to said top and bottom layers, and wherein said at least one middle layer is supported between the top layer and the bottom layer and comprises a plurality of openings;
• and
• a plurality of truss support baffles constructed of a heat weldable material, a first plurality of truss support baffles disposed between the at least one middle layer and said interior facing surface of the top layer, and a second plurality of truss support baffles disposed between the at least middle layer and the interior facing surface of the bottom layer, wherein said first and second plurality of truss support baffles are spot welded at predetermined locations between the top layer, the middle layer, and the bottom layer, and wherein predetermined regions of said first plurality of truss baffles are welded at predetermined points directly to predetermined regions of said second plurality of truss baffles through said plurality of openings in said at least one middle layer.

An inflatable sleeping pad comprising:

• an inflatable pad having a top layer and a bottom layer, said top and bottom layers disposed parallel to one another and having a length and a width, wherein said top and bottom layers each include an interior facing surface, and wherein said interior facing surface of said top layer includes at least a plurality of heat weldable regions, and wherein the interior facing surface of said bottom layer is coated with a polyurethane coating on said interior facing surface and on an outer surface thereof;
• a middle layer constructed of a thermal energy reflective material having a length and a width and disposed parallel to said top and bottom layers, and wherein said middle layer is supported between the top layer and the bottom layer and comprises a plurality of openings;
• and
• a plurality of truss support baffles constructed of a heat weldable material, a first plurality of truss support baffles disposed between the at least one middle layer and the interior facing surface of said top layer, and a second plurality of truss support baffles disposed between the at least middle layer and the interior facing surface of said bottom layer, wherein said first and second plurality of truss support baffles are spot welded to each other at predetermined locations between the top layer, the middle layer, and the bottom layer, and wherein said first plurality of truss baffles are welded at predetermined points directly to said second plurality of truss baffles through said plurality of openings in said middle layer.

An inflatable sleeping pad comprising:

• a top layer;
• a bottom layer;
• a middle layer disposed between the top layer and the bottom layer and having a plurality of openings extending therethrough;
• a first plurality of truss baffles disposed between the top layer and the middle layer, each of said first plurality of truss baffles having a first predetermined welding point and a second predetermined welding point spaced from the first predetermined welding point;
• and
• a second plurality of truss baffles disposed between the middle layer and the bottom layer, each of said second plurality of truss baffles having a first predetermined welding point and a second predetermined welding point spaced from the first predetermined welding point;
• wherein said top layer, bottom layer, and middle layer are arranged substantially parallel to one another;
• wherein the first predetermined welding spots of the first and second plurality of truss baffles are welded to the top and bottom layers, respectively;
• and
• wherein each second predetermined welding spot of each of the first plurality of truss baffles is welded to a second predetermined welding spot of a second truss baffle through an opening of the middle layer.
