Functional Pillow for Preventing Head Deformation of Infants Due to Posture

Abstract

The present invention relates to a functional pillow for preventing positional head deformity of an infant. The functional pillow includes an inner foam member which is porous, an outer cover which encloses the inner foam member and includes a plurality of through-holes formed thereon, a head seating portion which is formed on at least one of a top surface and a bottom surface of a pillow body which includes the inner foam member and the outer cover in an eccentric position to allow a head to be placed thereon, and at least one layered auxiliary pillow which is inserted into the head seating portion and includes an auxiliary head seating portion of a different size formed on a surface. A degree of layering of the auxiliary pillow is different according to a head size.

What is claimed is: 
     
         1 . A functional pillow for preventing positional head deformity of an infant, the functional pillow comprising:
 an inner foam member which is porous;   an outer cover which encloses the inner foam member and comprises a plurality of through-holes formed thereon;   a head seating portion which is formed in an eccentric position from a center of a pillow body which comprises the inner foam member and the outer cover; and   at least one auxiliary pillow which is inserted into the head seating portion and is layered,   wherein the auxiliary pillow comprises an auxiliary head seating portion formed on a surface thereof and a degree of layering is different according to a head size.   
     
     
         2 . The functional pillow as claimed in  claim 1 , wherein a size of the auxiliary head seating portion decreases toward an upper layer of the auxiliary pillow. 
     
     
         3 . A functional pillow for preventing positional head deformity of an infant, the functional pillow comprising:
 an inner foam member which is porous;   an outer cover which encloses the inner foam member and comprises a plurality of through-holes formed thereon;   an insertion recess which is formed on at least one of a top surface and a bottom surface of a pillow body which comprises the inner foam member and the outer cover; and   at least one replaceable auxiliary pillow which is inserted into the insertion recess and comprises a head seating portion of a different size individually formed to allow a head to be placed thereon,   wherein any one of the insertion recess and the head seating portion is formed in an eccentric position from a center of the pillow body.   
     
     
         4 . The functional pillow as claimed in  claim 3 , wherein the head seating portion is positioned at a point of about ½ to ⅓ of the pillow body from a lower end of the pillow body. 
     
     
         5 . The functional pillow as claimed in  claim 3 , wherein the pillow body is formed such that a thickness around a neck falls within a range of about 50% to 70% of a thickness above a head. 
     
     
         6 . The functional pillow as claimed in  claim 3 , wherein the inner foam member is formed by enclosing a soft elastic material with a cushiony air mesh material or is formed of an air mesh material itself. 
     
     
         7 . The functional pillow as claimed in  claim 3 , wherein the head seating portion is formed in a hemisphere shape.
