Air mattress

Abstract

The invention relates to an air mattress comprised of at least one air chamber made of strips of an air-tight, water vapor permeable or water vapor impermeable material that are welded or glued together. The air chamber is provided with a closable valve for letting air in and out, and the air chamber is filled with a down feather material or a synthetic fiber insulation material.

1 - 8 . (canceled)  
   
   
       9 . An air mattress, comprising at least one air chamber of contiguous, permanently attached lengths of an air-impermeable material, said air chamber including a closable valve for admitting and releasing air; 
 wherein said air chamber is filled with a thermally insulting filler material; and    said valve is lined with an open-pore material for preventing the escape of said thermally insulating filler material.    
   
   
       10 . The air mattress of  claim 9 , 
 wherein said air mattress includes bottom and top surfaces; and    said air chamber is subdivided by at least one strut, said strut being secured to said bottom and top surfaces of said air mattress.    
   
   
       11 . The air mattress of  claim 10 , wherein said at least one strut is air-permeable.  
   
   
       12 . The air mattress of  claim 10 , wherein said at least one strut is air-impermeable.  
   
   
       13 . The air mattress of  claim 10 , wherein said at least one strut is permanently attached to said bottom and top surfaces of said air mattress.  
   
   
       14 . The air mattress of  claim 10 , 
 wherein said at least one strut includes at least two struts; and    wherein said at least two struts are evenly disposed within said air mattress and are disposed transverse to at least one of said bottom and top surfaces of said air mattress.    
   
   
       15 . The air mattress of  claim 9 , wherein said valve is a safety valve for preventing the outflow of air from the interior of said air mattress.  
   
   
       16 . The air mattress of  claim 9 , wherein said valve is adapted to be connected to a pump having a flexible casing provided with an inlet valve, and said casing is filled with an open-pore, self-expanding foam.  
   
   
       17 . The air mattress of  claim 9 , wherein said thermally insulating filler material is down.  
   
   
       18 . The air mattress of  claim 9 , wherein said thermally insulating filler material is a synthetic insulating fiber.  
   
   
       19 . The air mattress of  claim 9 , wherein said air permeable material is water-vapor permeable.  
   
   
       20 . The air mattress of  claim 9 , wherein said air permeable material is water-vapor impermeable.  
   
   
       21 . The air mattress of  claim 10 , wherein said struts are directly attached to said bottom and top surfaces of said air mattress.  
   
   
       22 . The air mattress of  claim 10 , wherein said struts are indirectly attached to said bottom and top surfaces of said air mattress through an attachment means.  
   
   
       23 . The air mattress of  claim 22 , wherein said attachment means includes tape.  
   
   
       24 . The air mattress of  claim 10 , wherein said at least one strut is perpendicular to said at least one of said bottom and top surfaces of said air mattress.  
   
   
       25 . The air mattress of  claim 10 , wherein said at least one strut is obliquely disposed to said at least one of said bottom and top surfaces of said air mattress.
