Triangular pillow

Abstract

A pillow comprising a pillow body having a triangular shaped cross-section is disclosed. In accordance with embodiments of the present invention, the pillow comprises a first angle at a right angle; a second angle at an arcual angle; and a third angle at a plane angle. The width of the second and third angles are provided at 4 cm to 8 cm and the length of each side along the right angle of the pillow is provided at 8 cm to 22 cm. The pillow is structured such that the physical curvature of the user's neck vertabra is reasonably and comfortably maintained and supported when the user lies horizontally. The pillow is structured to adapt to the curvature along the head, neck, and chest of a user, such that the neck is relaxed and moderately drawn, while the muscular ligaments of the neck and small articulation of the neck vertebrae are automatically adjusted, thereby effectively protecting the neck vertebra.

       10 . The pillow of  claim 5 , wherein the flexible and elastic material is selected from a group consisting of sponge, polyurethane, latex, flexible plastics and combinations thereof. 
   
   
       11 . The pillow of  claim 1 , wherein two of the resting edges are curved. 
   
   
       12 . A pillow comprising a pillow body having a cross section shaped as a right-angled isosceles triangle with two arcual angles, at least two resting edges and three planar resting surfaces. 
   
   
       13 . The pillow of  claim 12 , wherein a length of the pillow body along each side of the right angle is between 8 cm and 22 cm long. 
   
   
       14 . The pillow of  claim 12 , wherein an external width of each of the two arcual angles is between 4 cm and 8 cm wide. 
   
   
       15 . The pillow of  claim 13 , wherein an external width of each of the two arcual angles is between 4 cm and 8 cm wide. 
   
   
       16 . The pillow of  claim 12 , wherein a width of each of the two arcual angles is no less than 4 cm. 
   
   
       17 . The pillow of  claim 13 , wherein a width of each of the two arcual angles is no less than 4 cm. 
   
   
       18 . The pillow of  claim 12 , wherein the pillow body is made of a flexible and elastic material. 
   
   
       19 . The pillow of  claim 12 , wherein the flexible and elastic material is selected from a group consisting of sponge, polyurethane, latex, flexible plastics and combinations thereof. 
   
   
       20 . The pillow of  claim 12 , wherein two of the resting edges are curved.
