Dual layer sleeping pad

Abstract

A dual layer inflatable sleeping pad has an upper inflatable layer coupled to a lower inflatable layer. The dual-layer sleeping pad has an inflation valve for the lower layer and a second inflation valve for the upper layer. These valves are in fluid communication with their respective layer, thereby allowing air to travel in and out of each layer as needed. Each layer is independent from one another and the inflation level of each layer can be independently adjusted.

The invention claimed is: 
     
         1 . A dual-layer, inflatable sleeping pad, comprising:
 an upper inflatable layer, wherein said upper inflatable layer is configured for being inflatable to a first user-selected inflation level;   a lower inflatable layer, coupled to said upper layer, wherein said lower inflatable layer is configured for being inflatable to a second user-selected inflation level independent of said first user selected inflation level;   a first inflation valve located on said lower inflatable layer and in fluid communication with said lower inflatable layer and configured to allow air to travel into and out of said lower inflatable layer; and   a second inflation valve, located on said upper inflatable layer and in fluid communication with said upper inflatable layer and configured to allow air to travel into and out of said upper inflatable layer.   
     
     
         2 . The sleeping pad of  claim 1 , wherein said upper inflatable layer and said lower inflatable layer further comprise an open cell foam material. 
     
     
         3 . The sleeping pad of  claim 2  wherein said open cell foam material of said at least one of said upper and lower inflatable layers include at least one hollow channel disposed through said open cell foam material. 
     
     
         4 . The sleeping pad of  claim 1 , wherein said upper and lower inflatable layers are coupled together using one of the methods selected from the group consisting of: a plurality of welded tabs, a plurality of semi-permanent, releasable fasteners and stitching. 
     
     
         5 . The sleeping pad of  claim 1 , wherein said first and second inflation valves are located on a same end of said upper and lower inflatable layers. 
     
     
         6 . The sleeping pad of  claim 1 , wherein said lower inflatable layer has an upper surface and a lower surface, wherein said lower surface is made from a durable and abrasion-resistant material. 
     
     
         7 . The sleeping pad of  claim 6 , wherein said upper inflatable layer has an upper surface and a lower surface, wherein said upper surface includes a fabric material. 
     
     
         8 . The sleeping pad of  claim 1 , further comprising a separation layer, wherein said separation layer is located between said upper inflatable layer and said lower inflatable layer. 
     
     
         9 . The sleeping pad of  claim 8 , wherein said separation layer is comprised of a metallic material. 
     
     
         10 . The sleeping pad of  claim 8 , wherein said separation layer is comprised of an insulation material. 
     
     
         11 . The sleeping pad of  claim 1 , wherein said upper layer comprises open cell foam and said lower layer comprises inflatable baffles. 
     
     
         12 . The sleeping pad of  claim 1 , wherein said upper layer comprises inflatable baffles and said lower layer comprises open cell foam. 
     
     
         13 . The sleeping pad of  claim 1 , comprising a middle layer disposed between said upper inflatable layer and said lower inflatable layer, said middle layer including metallic material. 
     
     
         14 . The sleeping pad of  claim 1 , wherein one of said upper inflatable layer and said lower inflatable layer further comprise an open cell foam material.
