Flame resistant shelter

Abstract

A flame-resistant fabric for shelters including a flame-resistant interior layer, an flame-resistant, insulating middle layer adjacent the interior layer, and a flame-resistant exterior layer adjacent the insulating middle layer. The flame-resistant fabric is capable of being formed into a flame-resistant, insulated shelter for use in extreme weather.

1 . A shelter comprising:
 at least one wall made of a flame-resistant fabric, the flame-resistant fabric comprising:
 a flame-resistant interior layer; 
 a flame-resistant, insulating middle layer adjacent the interior layer; and 
 a flame-resistant exterior layer adjacent the insulating middle layer, wherein the insulating middle layer is quilted between the interior layer and the exterior layer to form the flame-resistant fabric; and 
   an opening in the wall for entering and exiting the shelter.   
     
     
         2 . The shelter of  claim 1 , wherein the shelter is portable. 
     
     
         3 . The shelter of  claim 2 , wherein the shelter is a tent. 
     
     
         4 . The shelter of  claim 1 , wherein the middle layer is quilted at an interval of approximately 5-25 inches. 
     
     
         5 . The shelter of  claim 1 , wherein the middle layer is a blend of fibers. 
     
     
         6 . The shelter of  claim 5 , wherein the blend of fibers includes at least one of modacrylic, aramid, and polyester fibers. 
     
     
         7 . The shelter of  claim 1 , wherein the flame-resistant fabric has a basis weight greater than approximately 2.5 ounces per yard squared, a thickness greater than approximately 0.25 inches, and an R-value greater than approximately 0.2. 
     
     
         8 . The shelter of  claim 1 , wherein the insulating middle layer has a basis weight greater than approximately 2.0 ounces per yard squared, a thickness greater than approximately 0.15 inches, and an R-value greater than approximately 0.2. 
     
     
         9 . A shelter comprising:
 at least one wall made of a flame-resistant fabric, the flame-resistant fabric comprising:
 a flame-resistant interior layer; 
 a flame-resistant, insulating middle layer adjacent the interior layer, the insulating middle layer comprising a blend of fibers including at least one of modacrylic, aramid, and polyester fibers; and 
 a flame-resistant exterior layer adjacent the insulating middle layer. 
   
     
     
         10 . The shelter of  claim 9 , wherein the middle layer is quilted between the interior layer and the exterior layer. 
     
     
         11 . The shelter of  claim 10 , wherein the middle layer is quilted at an interval of approximately 5-25 inches. 
     
     
         12 . The shelter of  claim 9 , wherein the flame-resistant fabric has a basis weight greater than approximately 2.5 ounces per yard squared, a thickness greater than approximately 0.25 inches, and an R-value greater than approximately 0.2. 
     
     
         13 . The shelter of  claim 9 , wherein the insulating middle layer has a basis weight greater than approximately 2.0 ounces per yard squared, a thickness greater than approximately 0.15 inches, and an R-value greater than approximately 0.2. 
     
     
         14 . A shelter comprising:
 a collapsible and erectable frame;   a ceiling and a plurality of side walls connected to the frame to form a shelter, the ceiling and side walls made of a flame-resistant fabric, the flame-resistant fabric comprising:
 a flame-resistant interior layer; 
 a flame-resistant, insulating middle layer adjacent the interior layer; and 
 a flame-resistant exterior layer adjacent the insulating middle layer; and 
   an opening in at least one side wall for entering and exiting the shelter.   
     
     
         15 . The shelter of  claim 14 , wherein the flame-resistant fabric has a basis weight greater than approximately 2.5 ounces per yard squared, a thickness greater than approximately 0.25 inches, and an R-value greater than approximately 0.2. 
     
     
         16 . The shelter of  claim 14 , wherein the insulating middle layer has a basis weight greater than approximately 2.0 ounces per yard squared, a thickness greater than approximately 0.15 inches, and an R-value greater than approximately 0.2. 
     
     
         17 . The shelter of  claim 14 , wherein the shelter is portable. 
     
     
         18 . The shelter of  claim 14 , wherein the middle layer is a blend of fibers. 
     
     
         19 . The shelter of  claim 15 , wherein the blend of fibers includes at least one of modacrylic, aramid, and polyester fibers. 
     
     
         20 . The shelter of  claim 14 , wherein the insulating middle layer is quilted between the interior layer and the exterior layer to form the flame-resistant fabric
