WARREN S. RAD FORD i mj @3/ m z ATTORNEYS United States Patent O 3,555,582 THERAPEUTIC DEVICE Warren S. Radford, 12306 Miles Ave., Cleveland, Ohio 44105 Filed Sept. 26, 1968, Ser. No. 762,677 Int. Cl. A61g 7/06 US. Cl. -338 ABSTRACT OF THE DISCLOSURE A therapeutic device for supporting a portion of the human body when disposed in a reclining or semi-reclining position including a generally wedge-shaped body. The body includes an upper surface which extends angularly between support surfaces which are disposed in generally perpendicular relation to one another. The angular disposition of the upper surface is greater with respect to one support surface than with respect to the other support surface enabling the human body to be disposed in a semi-reclining or generally reclining position, respectively and adapted to position and support the'respective parts of the body in predetermined relative position, providing maximum comfort and improved posture. C

Claims BACKGROUND OF THE INVENTION This invention relates to a therapeutic support device, and more particularly to pillow-like devices adapted for supporting and positioning the neck, head and back of a human body.

Recently, there has been a notable increase in the number of physical ailments associated with the back and related portions of the human body. To a great extent, these ailments are a result of improper positioning of the relative portions of the body, that is, the head, neck and back when disposed in a reclining position, such as lying on a couch or floor for watching television, or when disposed in a semi-reclining position, such as for reading in bed or the like.

In the past, many devices have been provided for supporting thelbody in the above positions, but such devices have primarily served only as props without any concern for the proper positioning and/or orientation of the respective parts of the body. In addition, such devices have been useful lonly to the extent that they can support the body in a single position or result in improper orientation of the parts of the body when disposed in one or more different positions.

SUMMARY OF THE INVENTION The present invention contemplates providing a scientifically structured support device for supporting the head, neck and back of the human body which may be disposed in either a reclining or semi-reclining position and cornprises a unitary body portion having a plurality of support surfaces and a sinuously curved upper surface adapted to engage and support the body of an occupant.

The upper surface extends between and is angularly disposed with respect to the support surfaces and includes pairs of convex and concave portions disposed in alternately merging relationship lengthwise thereof. In the form shown, the support surfaces are generally flat, and preferably disposed in generally perpendicular relation to one another, and which define with the upper surface a generally wedge-shaped configuration for the body. The upper surface is disposed at a greater angle with respect to one support surface than another of the support surfaces for supporting the body of the occupant in a reclining or semi-reclining position, as desired. In addition, the upper surface includes an upper and lower convex portion and ice upper and lower concave portions when being supported on one of said support surfaces. One of the support surfaces has a greater transverse length than the other of the support surfaces with the upper convex portion disposed adjacent the support surface having a lesser transverse length and the lower concave portion being disposed adjacent the support surface having the greater transverse length. The lower concave portion includes a generally flat surface portion which terminates in the longer adjacent support surface. The upper surface merges with the back surface having a lesser transverse length adjacent the upper concave portion and defines an angle therebetween which is greater than the included angle defined by the generally flat surface portion of the lower concave portion and the adjacent support surface.

By the foregoing arrangement, there is provided a therapeutic support device :which when in use may be supported on a plurality of support surfaces, and which will position the occupants body in a generally reclining position when supported on one support surface and position the occupants body in a generally semi-reclining position when supported by the other support surface. In addition, the device is arranged to position the respective portions, that is head, neck and back, in proper orientation with respect to one another whether the body is positioned in either the reclining or semi-reclining position. Furthermore, the contour of the device is arranged so that when the body is in the above respective positions, the occupant may read, study or watch TV without neck and/or eye strain. Still further, the contour of the device: is well suited for use when lying on ones side and permits comfort and therapeutic positioning heretofore unavailable from previously known devices.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a generally perspective view, partially cut away, of the novel therapeutic support device of the present invention;

FIG. 2 is a side elevation view of the device shown in FIG. 1;

FIG. 3 is a back elevation view of the device of the present invention when viewed from the left-hand side of FIG. 2; and

FIG. 4 is a front elevation view of the support device of the present invention when viewed from the right-hand side of FIG. .2.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to FIGS. 1 and 2 of the drawings, the therapeutic support device of the present invention is illustrated generally at 2 and embodies a portable article adapted to be positioned on a floor, sofa, bed or the like. The device 2 is adapted to support a portion of the human body, including the headand neck, in a predetermined position, whereby maximum comfort is achieved when the body is in a reclining or semi-reclining position.

The article comprises a unitary, one-piece generally wedge-shaped body 4 being defined, when viewed in side elevation as shown in FIG. 2, by the generally flat support surfaces 6 and 8, respectively, and upper surface 20, which intersects the bottom 6 and back 8 surfaces, to form upper and front edges 14 and 16, respectively. Preferably, the body 4 is generally rectangular in configuration when viewed in back (FIG. 3) and front (FIG. 4) elevation, being defined by generally parallel opposite side surfaces 10 and 12, which extend generally perpendicularly with respect to the bottom surface 6 and upper edge 14. Preferably, the upper edge 14 extends generally parallel with respect to the bottom surface 6 and the front edge 16.

In the preferred embodiment, the interior of the body comprises a resilient cushion member 11 which is pref-.

erably made of a polymeric foam, such as urethane foam, having a density of pounds p.s.i., but may be made of any suitable resilient material or combination of materials which will provide a relatively firm yet resilient cushioned support. The cushion member is preferably covered on all surfaces by a fabric cover member 17 or other suitable material, such as polyvinyl chloride. The cover member 30 may be made in the form of a bag or envelope having an open end (not shown) into which the cushion member 11 may be inserted, whereupon, the open end of the cover member 30 may be sealed closed in any suitable manner.

In the form shown, the bottom surface 6 and back surface 8 are generally fiat and disposed in generally perpendicular relation to one another enabling the body to be supported on either the back or bottom surface, as desired. Preferably, the upper surface 20 is disposed in generally angular relationship with respect to the back and bottom surfaces so that an imaginary plane defined by the edges 14 and 16 will define an angle, such as a, with the back surface 8 which is greater than an angle, such as g, defined by such imaginary plane with the bottom surface 6, resulting in one support surface, such as 6, having a greater transverse length than the other. By this arrangement, the body of the user can be positioned in a more upward position when the pillow is resting on the back surface 8 than when the pillow is resting on the bottom surface 6.

The sinuously curved upper surface 20 of the cushion member 11 includes a plurality of alternately disposed convex 15, 17 and concave 19, 21 portions which merge smoothly with one another to form a continuous surface, and which are angularly disposed with respect to one another being adapted to position certain portions of the users head, neck and back in predetermined relation with respect to one another when the support is resting either on the bottom surface 6 or the back surface 8. As shown the upper surface 20 extends from the upper edge 14 generally forwardly, and slightly downwardly at an angle b which is greater than the angle a defining the upper convex portion 15. The surface 20 then curves generally downwardly and forwardly defining an angle c with the back surface 8 which is less than the angle a so that the convex portion 15 is positioned outwardly of the imaginary plane C. The front surface then curves gradually generally forwardly and upwardly defining an angle d with the back surface 8 which is greater than the angle a forming the upper concave portion 19, and then curves gradually generally downwardly to define an angle e with the back surface 8 which is less than the angle a forming the lower convex portion 17. Preferably, the outermost portion of the convex portion 17 is generally tangent to the imaginary plane C. The upper surface 20 then curves still generally forwardly and downwardly and then may extend generally asymptotically or linearly forwardly and downwardly with respect to the bottom surface 6 forming a generally fiat surface portion 23. The fiat surface 23 terminates in the linear front edge 16 which is common to the bottom surface 6. As can be seen, by this arrangement, only the convex portion 15 is positioned outwardly of the plane C while the portions 19 and 21 are positioned tangent to or inwardly of the plane C.

To achieve such, the angle 12 is greater than the angle d, and the angle d is greater than angle 1 while the angle 0 is greater than the angle e, and both angles 0 and e are less than angles b, d and f.

In addition, the transverse distance between the outermost point 25 of the upper convex portion 15 and the surface 6 is greater than the transverse distance between the innermost point 27 of the upper concave portion 19 and the'surface 6, and the transverse distance between the innermost point 27 and the surface 6 is greater than the transverse distance between the outermost point 29 of thelower convex portion 17 and-the surface 6 while the transverse distance between the outermost point 29 and the surface 6 is greater than the transverse distance between the innermost point 30 of the lower concave portion 21. The transverse distance between the above points 25, 27, 29 and 30 and the surface 8 is opposite to that mentioned above with the point 30being disposed the greatest distance away from and the point 25 being disposed the closest to the surface 8.

By way of example, the following table A gives typical dimensions corresponding to' the representative letters on the drawings for one sizeof support which would be satisfactory for most applications: 1

Table A Dimension location: i Inches When the device 2 is resting on the bottom surface 6, the concave portions 19 and 21 are adapted to receive the posterior occupit and posterior mid-dorsum of the user, whereas, when the device is resting on the back surface 8, the concave portions 19 and 21 are adapted to receive and properly position the posterior mid-sacrum and postterior mid-dorsum, respectively.

In addition, the convex portion 17 is adapted to properly orient the posterior mid-cervical region with respect to the previously mentioned portions of the occupants body when disposed in a reclining position, such as when the device is resting on the bottom surface 6, or in a semi-reclining position, such as when the device is resting on the back surface 8.
