Self-ventilating and self-cooling variable geometry pillow

Abstract

A self-ventilating and self-cooling variable geometry pillow comprising a middle module comprising a core composed of an open-cell shape memory material and a cores-envelope that surrounds the core; a first outer module connected to the middle module, the first outer module comprising a core composed of an open-cell shape memory material and a cores-envelope that surrounds the core; a second outer module connected to the middle module, the second outer module comprising a core composed of an open-cell shape memory material and a cores-envelope that surrounds the core; a first articulation crease that allows the first outer module to rotate with respect to the middle module; and a second articulation crease that allows the second outer module to rotate with respect to the middle module. The pillow's variable geometry accommodates various types of sleepers.

       2 . The pillow of  claim 1  wherein the first outer module, the second outer module and the middle module permit air to flow through to dissipate body generated heat.  
   
   
       3 . The pillow of  claim 1  wherein the first outer module is rotated about the first articulation crease so a top surface of the first outer module contacts a top surface of the middle module.  
   
   
       4 . The pillow of  claim 1  wherein the second outer module is rotated about the second articulation crease so a top surface of the second outer module contacts a top surface of the middle module.  
   
   
       5 . The pillow of  claim 1  wherein the core and the cores-envelope are composed of open-cell shape memory materials that permit airflow to dissipate body generated heat.  
   
   
       6 . The pillow of  claim 1  wherein the first outer module and the second outer module are rotated about the first articulation crease and the second articulation crease to move the pillow from a flat configuration to a folded configuration.  
   
   
       7 . The pillow of  claim 1  further comprising a case enclosing the plurality of modules, the case composed of a breathable material having a plurality of holes.  
   
   
       8 . The pillow of  claim 1  wherein the core-envelope is composed of an open-weave shape memory material.  
   
   
       9 . A pillow comprising: 
 a plurality of modules wherein each of the plurality of modules is connected to at least one other module and wherein each of the plurality of modules comprises a core composed of open-cell shape memory material and a cores-envelope that surrounds the core; and    at least one articulation crease that allows one of the plurality of modules to rotate with respect to the other modules,    wherein the plurality of modules facilitate airflow to dissipate body generated heat.    
   
   
       10 . The pillow of  claim 9  wherein one of the plurality of modules is rotated about the articulation crease so a top surface of the module contacts a top surface of another module.  
   
   
       11 . The pillow of  claim 9  wherein at least two of the plurality of modules are rotated about at least one articulation crease to move the pillow from a flat configuration to a folded configuration.  
   
   
       12 . The pillow of  claim 9  further comprising a case enclosing the plurality of modules, the case composed of a breathable material having a plurality of holes.  
   
   
       13 . A pillow that facilitates airflow to dissipate body generated heat comprising: 
 a core composed of open-cell shape memory material;    a core-envelope that surrounds the core to support the core; and    a case enclosing the core-envelope, the case composed of a breathable material having a plurality of holes,    wherein the core, the core-envelope, and the case are all permeable to the flow of air to transfer heat from the pillow to the outside environment.    
   
   
       14 . The pillow of  claim 13  wherein the core-envelope is composed of an open-weave shape memory material.  
   
   
       15 . A pillow that permits airflow to dissipate body generated heat comprising: 
 a perimeter having a first side, a second opposing side, a third elongated side and a fourth elongated opposing side; and    a core within the perimeter having a substantial thickness of a shape memory material,    wherein the shape memory material has an open-cell configuration that is permeable to the flow of air to dissipate the body generated heat.    
   
   
       16 . The pillow of  claim 15  wherein the body has an ergonomic profile to accommodate various types of sleepers.  
   
   
       17 . The pillow of  claim 15  further comprising a core-envelope surrounding the core.  
   
   
       18 . The pillow of  claim 18  further comprising a case enclosing the core-envelope, the case composed of a breathable material having a plurality of holes.  
   
   
       19 . The pillow of  claim 15  wherein the core-envelope is composed of an open-weave shape memory material.  
   
   
       20 . The pillow of  claim 15  wherein the shape memory material returns to an original configuration after removal of a load.
