Abstract
An adjustable orthopedic support neck pillow which includes a contoured top layer made of a relatively soft viscoelastic foam material, and a plurality of supporting layers made of a relatively hard foam material, each supporting layer having tongue-and-groove structures to enable the contoured layer to be removably supported by one or more supporting layers.
Description
PATENT
Adjustable Orthopedic Neck Support Pillow Background of the Invention Field of the Invention The invention relates to adjustable orthopedic neck support pillows which can be mechanically customized to support a large variation of the size and preferences of individuals and which are made of foam materials having at least two different degrees of hardness, or softness.
Description of Prior Art Supportive pillows over the past thirty years have gone through many changes in seeking the ideal support surface for the head and neck. Variations included, but were not limited to the materials used for supportive nature of the pillow. It has generally been assumed that in creating the ideal sleep surface there would have to be a fine balance between support and comfort in order to maximize the benefit to the end user.
The consumer today has a multitude of choices when it comes to purchasing a pillow. Materials utilized for vary from down feathers, fiberfll, organic materials, granular materials, fluid filled and polyurethane foam.
Medical study and testing performed by Dr. Ruth Jackson has indicated that the best degree of support that a pillow could provide would be a pillow that actually supported the natural contour of the cervical lordotic curve. She proposed that a roll-like structure placed under the cervical spine would be the most beneficial PATENT
in providing proper support for the neck. Since this early concept and design the cervical contour pillow has evolved into numerous variations. Although all have included the principal concept of a cervical roll support for the neck, none has considered variations in the dimensions of the anatomy of different individuals and how these differences relate to the ultimate effectiveness of a pillow on an individualized basis. For example, a supportive pillow that is ill fitting could be detrimental to the user because it forces the user to conform to the support rather than conforming the support to the user's individualized needs and/or preferences.
Various methods of customization of pillows for both the cervical and lumbar spine are known. However, these variations range from intricate systems of support that are either adjustable through an inflatable component, a fluid filled component, and/or attachment of components through the use of hook-and-loop fastening devices, zippers and/or strapping.
Objects and Summary of the Invention The present invention provides an orthopedic support pillow that has a relatively soft foam top layer, a relatively hard foam second layer and that can be customized in terms of height in order to fit an individual's needs and/or preferences without the use of accessory devices such as hook-and-loop, elastic bands, zippers and straps and the like.

Detailed Description of Preferred Embodiments The preferred embodiment of the present invention is an adjustable orthopedic neck support pillow 20 that can be used by a user for sleeping either in the supine or side lying position. It includes of two semicylindrical support rolls 22, 24 of equal or, preferably of varying diameter which are symmetrical and which extend across to opposing ends of the pillow support surface. In Figure 1 the roll 22 has a radius of curvature of about 3 '/z inches, including top layer 23 and the roll 24 has a radius of curvature of about 3 inches, including top layer 23. The Figure 1 embodiment is the most preferred in terms of the radii of curvature. The region between and connecting the two semicylindrical support rolls is a valley 26 that functions to receive the head. In vertical dimension the structure includes four layers 23, 28, 30 and 32, with the top layer 23 and second layer 28 having the semicylindrical support rolls 22,24 and valley surface 26. Preferably, a 1 inch layer of conventional viscoelastic foam material 23 comprises the top surface of the pillow and is adhered to the layer 28. The viscoelastic foam material layer 23 adds softness and reduces pressure points over bony regions of the skull, while retaining the supportive adjustable features of a more rigid polyurethane foam for the base of the pillow. The rigidity of the base of the pillow provides a supportive structure for PATENT
the neck in order to maintain the natural lordotic curvature of the neck. A
completely viscoelastic pillow would provide softness, but would lack the supportive element necessary for a pain free night's sleep, and thus, is not preferred. Standard polyurethane foam pillows are rigid and supportive, but lack softness. Thus, an important feature of the present invention is the combination of a relatively firm base with a relatively soft top layer for the pillow of the present invention.
The dimensions of the pillow of course may vary. However, it is believed that the minimum dimensions that are useful for adult humans would be about 12 inches in width by about 18 inches length by about 5 inches in height when fully assembled. Also, the support roll minimum diameter would be about 2 '/z inches, and about a 'h inch difference in diameter between the two rolls. This diameter difference provides for half sizes, to further fine tune the pillow's height to a particular individual's use.
Referring to Figure 2, the third layer 30 includes a plurality of projections 34, 36 on its superior surface 38, and a plurality of conduits 40, 42 on its inferior surface 44. The fourth, or bottom layer 32 includes a superior surface 46 having a plurality of projections 48,50. These projections 48, 50, when connected with the conduits 40, 42 of the third layer 30 in a tongue-and-groove fashion, removably attach layer 32 to layer 30, and when projections 34, 36 are interconnected with the grooves (not numbered) in second layer 28, these layers are removably PATENT
interconnected as shown in Figure 3, to create a unitary support structure for the pillow's surface 23 or layer.
Alternatively, the pillow of the present invention may be made without middle layer 30, so that a unitary pillow results. Such a pillow would have a viscoelastic layer 23, but would not be adjustable in height.
With reference to Figure 6, projection 48 includes a cap 52 distally and proximally a shaft 54. The channel 40 is a negative image, or cavity of the projection 48 with a cap receiving area 56 and shaft receiving area 58. The diameter of the shaft 54 is somewhat narrower than , and is positioned axially to the cap 52, resulting in the lateral borders of the cap 52 protruding symmetrically laterally. When engagement between layers has occurred, the one layer that is proximally attached to the shaft 54 and the layer that is attached to the shaft receiving area 58 are connected and act as a unitary body.
For back sleeping, as show in Figure 4, it is important to provide the appropriate support to the cervical lordotic curve 60 which is supported by either of the semicylindrical support rolls 22, 24, roll 24 being used in the Figure 4 illustration. The effectiveness of these semicylindrical support rolls 22, 24 is directly related to the height of convexity 62 of the thoracic spine 64. A
greater the convexity of the thoracic spine 64 curve would require a larger vertical dimension of the semicylindrical support rolls, as well as a valley, for supporting the head.
Because convexities do vary from individual to individual it is an important feature of the present invention that the vertical height of the structures that support the PATENT
semicylindrical support rolls 22, 24, and the valley 26 may be varied to provide the support necessary and/or preferred for any individual. While the height of support layer 30 may be the same as the height of layer 32, the heights may also be chosen to be different, and curvatures other than semicylindrical may also be used In the side lying position, show in Figure 5, it is preferable to maintain the neck in a neutral anatomical position. The distance from shoulder to neck 66 will vary from individual to individual. By varying the height of the semicylindrical support rolls 22, 24, and the valley 26, such as by adding or removing layer 30 or layer 32, or choosing which of rolls 22, 24 is under the neck (roll 24 is under the neck in Figure 5), customization capability is provided for optimum individualized support.
In the preferred embodiment the dimensions are chosen so that relatively large individuals (larger 10 % of population) would require all three layers to be in position in order to provide support for the natural curvature of their cervical spine.
The average individual (average height and weight) would only require two layers and at the other end of the range, slight individuals would only require a single layer of support.
In addition to individual size and side of sleeping, other factors could influence the chosen vertical height and radius of curvature of the support pillow of the present invention. For example, whether the individual is predominantly a stomach or side sleeper, types of inherent deformity to the spinal curvature and, PATENT
most importantly, the individualized preference would be considered in making, and using a particular pillow configuration within the scope of the present invention.
Referring to Figure 7, an enlarged, cross-sectional view of an alternate tongue-and-groove connection for use in the present invention is shown. A
trapezoidal shaped projection 68 extends from the top, or superior surface of a layer and is sized and configured to fit into a corresponding trapezoidal cross-section channel or cavity 70 in the bottom surface of the adjoining, upper layer.
Figure 8 is a top view of the Figure 1 embodiment showing the rolls 22, 24 and the valley 26. Figure 9 is a side view of the Figure 1 embodiment showing top layer, 23, layer 28, layer 30 and bottom layer 32.
Figure 10 is a back view of the Figure 1 embodiment, showing the roll 22 in the background. Figure 11 is a front view of the Figure 1 embodiment with the roll 22 shown in the front position. Figure 12 is a bottom view of the Figure 1 embodiment.
The preferred material of construction for the relatively hard foam layer of present invention is a polyurethane foam, most preferably a commercial grade, such as 1035 RB12, or better. The relatively soft top layer 23, is preferably made of a viscoelastic foam, also known as memory foam, grade 1041 RBR foam, for the top layer, i.e., the contoured layer. Other materials of construction may be used, so long as they provide resiliency and support sufficient to function as a pillow.
This pillow construction offer 3 features:
1) Supportive with a firm adjustable base of polyurethane foam.

In Figure 1 the roll 22 has a radius of curvature of about 3 '/z inches, including top layer 23 and the roll 24 has a radius of curvature of about 3 inches, including top layer 23. The Figure 1 embodiment is the most preferred in terms of the radii of curvature. The region between and connecting the two semicylindrical support rolls is a valley 26 that functions to receive the head.

This diameter difference provides for half sizes, to further fine tune the pillow's height to a particular individual's use.
Referring to Figure 2, the third layer 30 includes a plurality of projections 34, 36 on its superior surface 38, and a plurality of conduits 40, 42 on its inferior surface 44. The fourth, or bottom layer 32 includes a superior surface 46 having a plurality of projections 48,50. These projections 48, 50, when connected with the conduits 40, 42 of the third layer 30 in a tongue-and-groove fashion, removably attach layer 32 to layer 30, and when projections 34, 36 are interconnected with the grooves (not numbered) in second layer 28, these layers are removably PATENT

Alternatively, the pillow of the present invention may be made without middle layer 30, so that a unitary pillow results. Such a pillow would have a viscoelastic layer 23, but would not be adjustable in height.
With reference to Figure 6, projection 48 includes a cap 52 distally and proximally a shaft 54. The channel 40 is a negative image, or cavity of the projection 48 with a cap receiving area 56 and shaft receiving area 58. The diameter of the shaft 54 is somewhat narrower than , and is positioned axially to the cap 52, resulting in the lateral borders of the cap 52 protruding symmetrically laterally. When engagement between layers has occurred, the one layer that is proximally attached to the shaft 54 and the layer that is attached to the shaft receiving area 58 are connected and act as a unitary body.
For back sleeping, as show in Figure 4, it is important to provide the appropriate support to the cervical lordotic curve 60 which is supported by either of the semicylindrical support rolls 22, 24, roll 24 being used in the Figure 4 illustration. The effectiveness of these semicylindrical support rolls 22, 24 is directly related to the height of convexity 62 of the thoracic spine 64. A
greater the convexity of the thoracic spine 64 curve would require a larger vertical dimension of the semicylindrical support rolls, as well as a valley, for supporting the head.
Because convexities do vary from individual to individual it is an important feature of the present invention that the vertical height of the structures that support the PATENT
semicylindrical support rolls 22, 24, and the valley 26 may be varied to provide the support necessary and/or preferred for any individual. While the height of support layer 30 may be the same as the height of layer 32, the heights may also be chosen to be different, and curvatures other than semicylindrical may also be used In the side lying position, show in Figure 5, it is preferable to maintain the neck in a neutral anatomical position. The distance from shoulder to neck 66 will vary from individual to individual. By varying the height of the semicylindrical support rolls 22, 24, and the valley 26, such as by adding or removing layer 30 or layer 32, or choosing which of rolls 22, 24 is under the neck (roll 24 is under the neck in Figure 5), customization capability is provided for optimum individualized support.
In the preferred embodiment the dimensions are chosen so that relatively large individuals (larger 10 % of population) would require all three layers to be in position in order to provide support for the natural curvature of their cervical spine.
The average individual (average height and weight) would only require two layers and at the other end of the range, slight individuals would only require a single layer of support.
