Supportive upper body constraint device

Abstract

A supportive upper body constraint device comprising a base comprising a foam material with a preselected impression load deflection (ILD) ratio for a desired resiliency, and a smooth-surface cover on the base comprising an elastomeric foam material with an ILD ratio less than the base. The device comprises opposing support members on the base, the cover supportingly disposed by the base and support members in a concave contour defining a cavity.

1 . A supportive upper body constraint device, comprising: 
 a base comprising a foam material with an impression load deflection (ILD) ratio greater than about 40; and    a cover on the base comprising a foam material with an ILD ratio less than the base.    
   
   
       2 . The device of  claim 1  wherein the cover comprises an elastomeric foam material with an ILD ratio less than about 14.  
   
   
       3 . The device of  claim 1  comprising opposing support members on the base, the cover supportingly disposed in a concave contour defining a cavity.  
   
   
       4 . The device of  claim 3  wherein the cover comprises a material having a smooth surface.  
   
   
       5 . The device of  claim 3  wherein the base and support members are unitarily constructed.  
   
   
       6 . The device of  claim 1  wherein the cover comprises a foam material with a density in the range of about 3.8 to 4 pounds per cubic foot  
   
   
       7 . A supportive upper body constraint device, comprising: 
 a base comprising a substantially flat longitudinal surface and an inclined surface;    a pair of opposing support members on the inclined surface; and    a cover continuously covering the support members and a portion of the inclined surface between the support members comprising a viscoelastic foam material.    
   
   
       8 . The device of  claim 7  wherein the support members are wedge-shaped, the cover supportingly disposed in a concave contour defining a cavity.  
   
   
       9 . The device of  claim 7  wherein the cover comprises a smooth surface.  
   
   
       10 . The device of  claim 7  wherein the base and support members are unitarily formed.  
   
   
       11 . The device of  claim 7  wherein the base comprises a foam material with an impression load deflection (ILD) ratio greater than 40.  
   
   
       12 . The device of  claim 7  wherein the cover comprises a foam with an ILD ratio less than 14.  
   
   
       13 . The device of  claim 12  wherein the cover comprises a foam material with a density in the range of about 3.8 to 4 pounds per cubic foot.  
   
   
       14 . A supportive upper body constraint device, comprising: 
 a base; and    means supported by the base for constraining the upper body by imparting a supporting engagement continuously molding and adjusting to a shape of the upper body maintaining contiguous contact against the upper body.    
   
   
       15 . The device of  claim 14  wherein the means for constraining is characterized by a cover comprising a viscoelastic foam material.  
   
   
       16 . The device of claim  165  wherein the means of r constraining is characterized by opposing support members on the base supporting the cover in a concave contour defining a central cavity.  
   
   
       17 . The device of  claim 16  wherein the means for constraining is characterized by wedge-shaped support members.  
   
   
       18 . The device of  claim 14  wherein the base comprises a foam material with an impression load deflection (ILD) ratio greater than 40.  
   
   
       19 . The device of  claim 15  wherein the means for constraining is characterized by the cover comprising a foam material with an ILD ratio less than 14.  
   
   
       20 . The device of  claim 15  wherein the means for constraining is characterized by the cover comprising a foam material with a density in the range of about 3.8 to 4 pounds per cubic foot.
