Under Head Pillow

Abstract

Elastic plastic material head pillow comprises flat base and flexible bolster along the front longitudinal pillow edge, whose top surface repeats the anatomical shape of the thoracocervical area, formed as a flexible tongue top and bottom surfaces arranged in parallel position in the middle section with thickness from 4 to 6 cm and two times lesser than the tongue length. The ration of thicknesses of tongue middle section, height on the pillow front edge and pillow base length is 1:3:7, respectively. The tongue top surface gradually descents at angle ranging from 35° to 45° to the pillow base plane translating into the top plane thereof forming the recess along pillow transversal axis, with ascending surface embodied in counterweight form, providing optimal vertebral column physiological position, preserving natural sagittal plane curvatures, reducing head and neck soft tissues applied pressure, and improving head cavity venous drainage.

1 . An under-head pillow comprising a flat base ( 1 ) and a roll ( 2 ) along the frontal longitudinal side of the pillow, upper surface ( 9 ) shaped as an indentation ( 10 ), which repeats the anatomical configuration of the cervico-thoracic region of the user's spine but lower surface ( 4 ) shaped as an indentation for the accommodation of the shoulder wherein the roll ( 2 ) is shaped as a tongue-like flexible protrusion with its upper ( 3 ) and lower ( 4 ) surfaces parallel to each other and has thickness of 4 to 6 cm, which is half the size of its length, the approximate relation of the thickness of the roll to the length of the protrusion to the length of pillow base is 1:3:7, the upper surface ( 3 ) of the roll ( 2 ) turns into the upper surface ( 9 ) of the pillow at an angle of approximately 35 to 45 degrees to the base ( 1 ) of the pillow, the upper surface ( 9 ) of the pillow is shaped as an indentation ( 10 ) the lower portion of which has a height of approximately twice the thickness of the roll ( 2 ) and, the indentation ( 10 ) flows into the slope running backwards ( 11 ) towards the back side ( 12 ) of the pillow, which acts as a counterweight. 
   
   
       2 . The under-head pillow as in  claim 1  wherein there are elements used for pillow stability attached to the backside of the pillow to prevent it from tilting when pressed down by the user. 
   
   
       3 . The under-head pillow as in  claim 2  supplied with a pillow cover, which has an attached weight acting as counterbalance and positioned along the backside of the pillow. 
   
   
       4 . The under-head pillow as in  claim 2 , wherein said elements comprise Velcro belts. 
   
   
       5 . The under-head pillow as in  claim 4  supplied with a pillow cover, which has an attached weight acting as counterbalance and positioned along the backside of the pillow. 
   
   
       6 . The under-head pillow as in  claim 2 , wherein said elements comprise weights. 
   
   
       7 . The under-head pillow as in  claim 6  supplied with a pillow cover, which has an attached weight acting as counterbalance and positioned along the backside of the pillow. 
   
   
       8 . The under-head pillow as in  claim 1  supplied with a pillow cover, which has an attached weight acting as counterbalance and positioned along the backside of the pillow.
