Neck and Head Stability Pillow

Abstract

A neck and head stability pillow comprises flat bottom half cylinder fixed to a flat bottom half toroid and both components compose a single pillow. The flat bottom half cylinder fits directly below the neck providing an adequate support and stability to the cervical area. The flat bottom half toroid where the head rests provides the necessary flexibility. The inner elliptic space where the user's occiput rests is created between the flat bottom half toroid arms fixed to the flat bottom half cylinder. The inner diameter between the flat bottom half cylinder and the semi circular flat bottom half toroid elevates the user's occiput rests above the mattress. This graduation assures that the head and neck remain as aligned as possible in its top to bottom axis. The flat bottom surface stabilizes the half toroid fixed to the half cylinder providing full protection and stability for the user's cervical area.

What is claimed is: 
     
         1 . A neck and head stability pillow comprising:
 a flat bottom half cylinder fixed to a flat bottom half toroid;   a flat bottom half toroid forms an inner elliptic curve fixed to the flat bottom half cylinder and both comprise a single unit;   a user's neck rests on the half cylinder; a flat bottomed half cylinder takes in to account the concave curve of the cervical spine to provide a suitable support to the user's neck contour; a flat bottomed half cylinder takes in to account natural human neck curvature to provide a suitable support to the contour of the user's neck;   a space, where the user's occiput rests is created between the arms of the flat bottom half toroid arms fixed to the flat bottom half cylinder;   a user's head rests on the inner diameter of the half toroid; a half toroid is such that the weight of the head rests on the inner sidewalls of the toroid; a function of the inner sidewalls of the toroid is cushioning the head providing flexibility and stability for the head motion;   a radius of the half toroid with its flat base gradually increases from two inches at the connection with half cylinder to four inches at the apex of the curve to maintain the head aligned with the neck; a inner diameter between the flat bottom half cylinder pillow and the semi circular flat bottom half toroid pillow elevates the parietal section of user's head above the mattress.   a pillow can be used equally by people who sleep on their backs or on their sides;   
     
     
         2 . This pillow of  claim 1  also comprises another embodiment:
 an alternate embodiment of the invention use occurs when the user instead of lying face up on the pillow moves his body and head to the left side or to the right side; while the lateral head rests on the flat bottom toroid the corresponding lateral side of the neck keeps receiving support from the half cylinder. 
 
     
     
         3 . The proportions and sizes could be smaller for travel pillows or small children pillows or regular size for house whole use. 
     
     
         4 . The pillow of  claim 1  wherein the pillow is compose of a same material: viscoelastic foam or tempur-pedic foam:
 a design of the invention provides the flexibility to select a variety of materials similar to the viscoelastic foam or tempur-pedic foam, it is up to the manufacturer; 
 a pillow casing formed of washable non allergenic material that can breathe such as cotton, pure virgin wool among others; 
 a pillow casing will fallow exactly the contour of the pillow leaving open the inner diameter of the toroid. 
 
     
     
         5 . This pillow of  claim 1  also comprises another embodiment:
 an alternative embodiment of this invention comprise of alternating a memory foam material to another similar material in one of the component and a different material in the other component that has little o no compressibility; 
 a alternative embodiment' maintains the sizes and proportions of the preferable embodiment. 
 
     
     
         6 . The design of the invention provides the flexibility to select a variety of manufacture processes:
 a most practical manufacture processes for mass production of the neck and head stability pillow is Reaction Injection Molding;   a hot wire foam cutter another manufacturing method where mass production is not an issue.
