Abstract

A pillow having a length, a width and a height for supporting a head of a reclining body. The pillow is formed of a core formed with variable displacement parameters along the length and width in the direction of the height. The core includes an outer region surrounding, at least in part, an inner region where the inner region forms one or more cavities within the outer region to establish the variable displacement parameters. The variable displacement parameters allow the head to deform the pillow in the direction of the height of the pillow in proximity to the cavities for controlling alignment of the head in a comfortable sleeping position.

Claims

exact text as granted — not AI-modified
1 . A pillow having a length, a width and a height for supporting a head of a reclining body comprising,
 a core formed with variable displacement parameters along the length and width in the direction of the height, said core including an outer region surrounding, at least in part, an inner region,   said inner region including one or more cavities within said outer region to establish said variable displacement parameters,   said variable displacement parameters for allowing the head to deform the pillow over said cavities for controlling alignment of the head in a comfortable sleeping position.   
   
   
       2 . The pillow of  claim 1  wherein, in the direction of said height, said pillow has a top and a bottom and wherein one or more of said cavities has a greater dimension near the top and a lesser dimension near the bottom. 
   
   
       3 . The pillow of  claim 1  wherein the core has a top surface forming a core-top arc. 
   
   
       4 . The pillow of  claim 3  wherein the cavities have cavity tops where the cavity tops have arcs substantially matching the core-top arc. 
   
   
       5 . The pillow of  claim 1  wherein one of said cavities has an opening for receiving a pouch for adjusting the firmness of the pillow. 
   
   
       6 . The pillow of  claim 1  wherein one of said cavities is a heart-shaped cavity. 
   
   
       7 . The pillow of  claim 6  wherein the heart-shaped cavity has an opening for receiving a heart-shaped pouch for adjusting the firmness of the pillow. 
   
   
       8 . The pillow of  claim 1  wherein one or more of said cavities is bounded by one or more truss members and wherein the truss members have greater dimensions near the top and lesser dimensions near the bottom. 
   
   
       9 . The pillow of  claim 8  wherein at least one of said truss members includes first and second legs separated by a spacer for forming ear wells. 
   
   
       10 . The pillow of  claim 8  wherein two of said truss members are spaced apart at ends of the pillow along the length to form a central head-well cavity between the trusses. 
   
   
       11 . The pillow of  claim 10  wherein the head-well cavity is asymmetrically located within the core in the direction of the width. 
   
   
       12 . The pillow of  claim 10  wherein the head-well cavity is symmetrically located within the core in the direction of the width. 
   
   
       13 . The pillow of  claim 10  wherein the truss members are flush with ends of the pillow. 
   
   
       14 . The pillow of  claim 1  further including a pillow cover for covering said core. 
   
   
       15 . The pillow of  claim 1  wherein said core includes an inflatable bladder for controlling displacement parameters of the core. 
   
   
       16 . The pillow of  claim 15  wherein said displacement parameters include height of the pillow. 
   
   
       17 . The pillow of  claim 15  wherein one of said cavities is a head-well cavity having a sidewall and said inflatable bladder controls an angle of said sidewall. 
   
   
       18 . A method of manufacturing a pillow comprising,
 cutting a foam member to form a core in the shape of a pillow with a length, a width and a height,   cutting the core to form an inner member in an inner region surrounded by an outer member in an outer region,   cutting said inner member to form trusses having spaces for one or more cavities,   fixing the trusses in the inner region to form the one or more cavities in the inner region surrounded, at least in part, by the outer region whereby the pillow is formed with variable displacement parameters along the length and width in the direction of the height.   
   
   
       19 . The method of  claim 18  wherein said cutting of the inner member forms legs and a spacer separating said legs for each of said trusses. 
   
   
       20 . The method of  claim 18  wherein said cutting of the core is asymmetrical in the direction of the width. 
   
   
       21 . The method of  claim 18  wherein said cutting of the core is symmetrical in the direction of the width.
