Ergonomic Pillow

Abstract

The invention relates to an ergonomic pillow consisting of a body with a modular profile based on two cylindrical side sections and an intermediate prism-shaped section that is substantially smaller in height. The elasticity characteristics of the pillow are such that, when the user rests his/her head thereon in any position, equal pressure is applied over the entire contact surface. The inventive pillow can have a modular structure based on two basic elements, namely a half-pillow and a laminar section, the number and shape of which can be selected according to the desired elasticity and height.

1 . Ergonomic pillow, characterized in that it has a body in which three sections are defined, two lateral sections ( 1 - 2 ), cylindrical and equal to one another, and an intermediate section ( 3 ), rectangular-prismatic and lower in height than the lateral sections, in such a way that between the body of the pillow and the support surface thereof a wide channel ( 8 ) is defined which separates the prismatic section of the support surface, both in a given position of the pillow as well as in its reverse position.  
   
   
       2 . Ergonomic pillow, according to  claim 1 , characterized in that the intermediate and prismatic section ( 3 ) is distorted by bulging, providing an additional elasticity to the pillow to the one generated by the material employed in the manufacturing thereof.  
   
   
       3 . Ergonomic pillow, according to the previous claims, characterised in that in use position thereof and after the distortion by bulging of its prismatic and intermediate section ( 3 ), between the pillow and the support surface two ventilation channels ( 9 - 10 ) are defined allowing convection air current to pass through it.  
   
   
       4 . Ergonomic pillow, according to  claim 1 , characterised in that it adopts a modular structure based on two basic elements, one ( 13 ) of which consists of a half-pillow, which is formed by sectioning by the symmetrical axis of an ergonomic pillow, according to  claim 1  and a second laminar element ( 14 ), of rectangular profile.  
   
   
       5 . Ergonomic pillow, according to  claim 4 , characterised in that the basic elements ( 13 - 14 ) have a consistency which changes according to the material it comprises which may be feather, cellulose padding, polyurethane or any other appropriate traditional material.  
   
   
       6 . Ergonomic pillow, according to claims  4  and  5 , characterised in that it is formed by means of the connection of the desired basic elements ( 13 - 14 ), selected in number and shape based on the desired height and elasticity, as well as the composition thereof.  
   
   
       7 . Ergonomic pillow, according to  claims 4  to  6 , characterised in that the upper half-pillow ( 13 ), where the head and neck of the user rests, creates a distortion in the pillow as a whole due to the elastic contraction of the structural material, which is equal in all the juxtaposed sections, producing by means of bulging, ventilation channels ( 15 ) for convection currents.  
   
   
       8 . Ergonomic pillow, according to previous claims, characterized in that it is reversible both in its longitudinal and annular sections, allowing its use by means of support on either of its two larger surfaces.
