Abstract
The foam core of a pillow is devided into three parts on the top of its length, and these three parts are forming parallel channels to each other, where the middle channel is deeper and wider than the side channels. The side channels are higher to allow one to sleep on the left or on the right side to obtain good sleeping pasture. On the top of the foam core a softer layer of foam or batting may be used.
Description
SPECIFICATION
This invention relates to a foam core for pillows to rest one's head while sleeping or just taking a nep.
A large variety of pillows are marketed and purchased to make sleeping as comfortable as possible. Among the latest are the foam pillows.
In younger age one could sleep almost in any position. It may not be true when a middle aged or an older person is concerned whose bone struc-ture is more brittle and receptive to wear. If the head elevation is too high or too low the overnight sleep may promote wear, restlessness and fatigue.
The feather or polyester pillows thickest part is at the middle and tapering off to the sides. When one intend to sleep on the left or on the right side the support is none existent to hold the head at a higher elevation to aline the neck vertebrae close to a horizontal position to obtain a good sleeping posture.
I have found that these disadvantages may be overcome by provid-ing two different heights for the main three sleeping positions. Dividing the foam core's length on the top into three parts in such a way that these three parts are forming parallel channels to each other. The middle channel is deeper and wider than the two side channels to support the head for sleeping on the back, and the two side channels for sleeping on the side channels at a higher elevation to obtain a good sleeping posture.
In drawings which illustrate embodiments of the invention, Fig.1 is the embodiments of the invention, Fig.2 is showing the foam core and the soft layer.
In Fig.1, 1 is the the foam core of the pillow, 2 is the middle channel, 3 and 4 are the side channels. In Fig.2, 1 is the foam core and 2 may be a Visco-Elastic Foam or a lower resilient foam than the foam core itself, or a layer or layers of batting to allow the head to sink from the weight and heat of the head and distribute the pressure to a larger area.
The foam core's measurements may deviate plus or minus 15%
without the added soft layer 2 as shown in Fig.2.
The middle channel's height at its lowest point measuring from the bottom of the foam core is between 1/10 th and 1/20 th of the body width at the shoulders, and the side channel's lowest point is between 1/5 th and 1/6 th of the body width at the shoulders.The length of the foam core is 26"
and the width is 14". The width of the middle channel is 10" and each side channel is 8". The side channel's curvature depth is 0.75 inches. Other con-sideration is the channels depth measurements, close to 1/10 th and 1/5 th for hard matrasses, and 1/6 th and 1 /20 th for soft matrasses.
The material used for the foam core may be a fire resistant con-ventional foam for pillows or none fire resistant. Latex or Visco-Elastic Foam may be used alone or as a layer 1 /2" to 2" in thickness on the top surface of the foam core, or a soft layer of a lower resiliant conventional foam, or batting from cotton or polyester may be used 1/2" to 2" in thickness.
