Pillow having structurally varying core and cover

Abstract

A pillow for supporting the head of a reclining body. The pillow has a core formed with variable displacement parameters along the length and width and the pillow has a cover formed of a soft material for encasing the core. The cover imparts a soft feeling to the head on the pillow and distributes the weight of the head over the core. The core and the cover are displaced by the head as a function of the displacement parameters of the core so that the pillow functions to control the alignment of the head in a comfortable sleeping position while maintaining natural neck and head alignment.

 a core having core variable displacement parameters along the pillow length and the pillow width in the direction of the pillow thickness for supporting the head in a non-distorting aligned position,   a cover having a cover chamber containing a fill where the cover chamber has a chamber thickness forming a portion of the pillow thickness, where the fill has fill displacement parameters and where the core is located within a core opening formed by the cover so that the cover encases the core, and   whereby the cover imparts a soft feeling to the head supported by the pillow and whereby the core and the cover are displaced by the head as a function of the displacement parameters to support the head in the non-distorting aligned position.

         5 . The pillow of  claim 4  wherein the core has a central region including a single hole. 
     
     
         6 . The pillow of  claim 4  wherein the core has a central region including one or more of said holes for aligning with the head and has two side regions offset from said central region for aligning with an ear of said head when the head is in a side-lying position. 
     
     
         7 . The pillow of  claim 6  wherein said side regions each include two holes. 
     
     
         8 . The pillow of  claim 4  wherein the central region of said core is formed by a foam layer having a volume where fifty percent or more of the volume is constituted by holes. 
     
     
         9 . The pillow of  claim 1  wherein the core includes one or more layers of foam including said core variable displacement parameters. 
     
     
         10 . The pillow of  claim 9  wherein said one or more layers are of uniform thickness. 
     
     
         11 . The pillow of  claim 1  wherein the core includes a plurality of layers of foam wherein at least one of said layers includes said core variable displacement parameters and wherein said cover includes an opening whereby one or more of said layers can be removed to modify the pillow displacement parameters. 
     
     
         12 . The pillow of  claim 10  wherein said opening is provided by a zipper in said cover. 
     
     
         13 . The pillow of  claim 1  where the core has a central region formed with a first wall and a second wall where the first and second walls extend in the direction of the length where the central region has a central ILD and the walls have a wall ILD whereby the neck of the reclining body is supported by and extends over one of said walls allowing the head to depress into the central region. 
     
     
         14 . The pillow of  claim 13  where the first wall has a greater width than the second wall whereby the head when extending over the first wall has greater support than when extending over the second wall. 
     
     
         15 . The pillow of  claim 1  where the chamber includes two or more compartments. 
     
     
         16 . The pillow of  claim 15  where a first compartment is on a top of the pillow and a second compartment is on a bottom of the pillow. 
     
     
         17 . The pillow of  claim 16  where the first compartment has a first volume for receiving a first quantity of fill and where the second compartment has a second volume for receiving a second quantity of fill where the first volume and the first quantity of fill are greater than the second volume and the second quantity of fill, respectively. 
     
     
         18 . A pillow for supporting a head and neck of a reclining body on a mattress where the pillow has a pillow length, a pillow width and a pillow thickness comprising,
 a core having a substantially uniform thickness and including a plurality of holes providing core variable displacement parameters along the pillow length and the pillow width in the direction of the pillow thickness for supporting the head in a nondistorting aligned position, the core including a central region and a first region on one side of the central region and a second region on another side of the central region,   a cover having a chamber for receiving a fill where the chamber has a chamber thickness forming a substantial portion of the pillow thickness, where the fill has fill displacement parameters substantially softer than the core variable displacement parameters and where the core is located within a core opening so that the cover encases the core, and   whereby the cover imparts a soft feeling to the head supported by the pillow and whereby the core and the cover are displaced by the head as a function of the displacement parameters to support the head in the non-distorting aligned position.   
     
     
         19 . The pillow of  claim 18  where the fill is one or more of synthetic and natural fibers. 
     
     
         20 . The pillow of  claim 18  where the central region is formed with a first wall and a second wall where the first and second walls extend in the direction of the length where the central region has a central ILD and the walls have a wall ILD whereby the neck of the reclining body is supported by and extends over one of said walls allowing the head to depress into the central region and where the first wall has a greater width than the second wall whereby the head when extending over the first wall has greater support than when extending over the second wall. 
     
     
         21 . A pillow for supporting a head and neck of a reclining body on a mattress where the pillow has a pillow length, a pillow width and a pillow thickness and where the mattress has a mattress length, a mattress width and a mattress thickness where the mattress includes mattress variable displacement parameters along the mattress length and the mattress width in the direction of the mattress thickness for supporting the body in a non-distorting aligned position comprising,
 a core having core variable displacement parameters along the pillow length and the pillow width in the direction of the pillow thickness for supporting the head in a non-distorting aligned position when located on the mattress with the length of the pillow perpendicular to the length of the mattress, said core variable displacement parameters tailored to match the mattress variable displacement parameters for alignment of the head and other parts of the body,   a cover having a cover chamber containing a fill where the cover chamber has a chamber thickness forming a substantial portion of the pillow thickness, where the fill has fill displacement parameters and where the core is located within a core opening formed by the cover so that the cover encases the core, and   whereby the cover imparts a soft feeling to the head supported by the pillow and whereby the core and the cover are displaced by the head as a function of the displacement parameters to support the head in the aligned position.
