Sleeping bag with integrated inflatable pillow

Abstract

A sleeping bag with an integrated inflatable pillow includes a sleeping bag wall extending longitudinally between opposed head and foot ends and having an outer shell and an interior lining. Retained adjacent the head end between the shell and the lining is a bladder including at least one gas tight bladder wall defining a fluid cavity for containing a predetermined volume of gas. A valve permits selective fluid communication between the fluid cavity and the atmosphere surrounding the bladder wall for the alternative inflation and deflation of the bladder.

What is claimed is:  
     
         1 . A sleeping bag with an integrated inflatable pillow, comprising: 
 a sleeping bag wall including an outer shell and an interior lining, the sleeping bag wall extending longitudinally between opposed head and foot ends; and    an inflatable bladder retained between the shell and the lining adjacent the head end, the bladder including at least one gas tight bladder wall defining a fluid cavity for containing a predetermined volume of gas.    
     
     
         2 . The sleeping bag of  claim 1  further comprising a valve depending from the bladder wall and facilitating the selective communication of fluid between the cavity and the atmosphere external to the bladder.  
     
     
         3 . The sleeping bag of  claim 1  wherein the bladder is irremovably incorporated within the sleeping bag wall.  
     
     
         4 . The sleeping bag of  claim 2  wherein the bladder is irremovably incorporated within the sleeping bag wall.  
     
     
         5 . The sleeping bag of  claim 1  wherein the a portion of the sleeping bag wall further comprises a bladder pocket into which, and from which, the bladder can be alternatively inserted and removed.  
     
     
         6 . The sleeping bag of  claim 5  further comprising at least one selectively releasable fastener for removably retaining the bladder in the bladder pocket.  
     
     
         7 . The sleeping bag of  claim 6  wherein the at one selectively releasable fastener includes at least one of 
 (i) a set cooperating hook and loop fasteners;  
 (ii) a snap;  
 (iii) a button; and  
 (iv) a zipper.  
 
     
     
         8 . The sleeping bag of  claim 5  further comprising a valve depending from the bladder wall and facilitating the selective communication of fluid between the cavity and the atmosphere external to the bladder.  
     
     
         9 . The sleeping bag of  claim 6  further comprising a valve depending from the bladder wall and facilitating the selective communication of fluid between the cavity and the atmosphere external to the bladder.  
     
     
         10 . The sleeping bag of  claim 7  further comprising a valve depending from the bladder wall and facilitating the selective communication of fluid between the cavity and the atmosphere external to the bladder.  
     
     
         11 . The sleeping bag of  claim 2  wherein the valve further includes nozzle accessible through the sleeping bag wall.
