Description

BACKGROUND OF THE INVENTION

The present invention is a new and improved apparatus, a new therapeutic or so-called “Body Tuning Cushion™,” for improving posture and gently flexing a user's spine into proper alignment with the head, arms, and shoulders.

Numerous spine-engaging devices are known to the art including those shown in U.S. Pat. Nos. 4,230,099; 5,180,386; 5,632,050; 5,797,154; 5,279,310; 5,987,675; 6,006,380; and 8,434,492. The disclosures of these references are understood to represent the state of the art.

SUMMARY OF THE INVENTION

The therapeutic or so-called “Body Tuning Cushion™” of the present invention provides a new and improved tuning apparatus for reconditioning the musculoskeletal system of the upper body (toward overcoming the negative impact gravity has upon the human spine), and the lower body (toward modifying how it supports a properly tuned and posed upper body). The primary objective of using the new therapeutic cushion is to utilize the effect of gravity while reducing muscular tension throughout the human body.

Daily use of the new therapeutic cushion introduces a unique quality of well-being and health awareness. The new therapeutic cushion is ergonomically designed to enhance the specific awareness of and the beneficial effect of gravity on the spine. The new device eases the spine into an enhanced supported condition. The user simply relaxes onto the new therapeutic cushion for very short time intervals; this provides a gentle flexion and stretching of the entire spine/torso while cradling the head.

Typically, all three vertebral sections of the spine (cervical, thoracic, and lumbar) have become habituated to supporting this upper body weight by settling into an often irretrievably compressed condition, while sitting or standing (resulting in poor posture). The new therapeutic cushion targets these three sections simultaneously flexing them into improved posture under the influence of gravity.

Specifically, the invention relies upon gravity to work effectively by actually allowing gravity to draw the arms and shoulders down into a corresponding alignment with the spine as the spine is oriented by the geometry of the new therapeutic cushion into proper posture.

Initially, three to five minutes of resting by a user laying horizontally upon the therapeutic cushion is preferred and is effective. However, there is no limit on the resting duration on the cushion, nor a limit to the number of times per day a user may use the cushion.

For a better understanding of the present invention and an appreciation of its attendant advantages, reference should be made to the accompanying drawings and the following detailed description.

DETAILED DESCRIPTION OF THE INVENTION

Referring to FIGS. 1-5, the new therapeutic cushion includes a head-engaging portion 30, an upwardly projecting apex portion 31 for engaging the back and the neck between cervical vertebrae C-3 to C-6 (vertebrae C-1 to C-6 are specifically numbered in FIG. 5); a “valley” 32 between the apex 31 and lower spine-engaging (thoracic, lumbar, sacral) portion 33. The new therapeutic cushion is fabricated from a medium density foam of the type well known in the cushioning art. An exemplary material for the therapeutic cushion body is polyurethane foam having the following properties:

Density        1.90 to 2.00
IFD 25%        50 to 60
IFD 65%        105 to 126
Tensile PSI    14
Elongation %   113
Tear PLI       1.11
CS 90%         3.5
HACS %         4.5
Fatigue Loss % 37.7
*CAL 117-2013  *Pass
Physical testing was done in accordance with ASTM D 3574-05.
*This certifies that this foam passes CAL 117-2013.

The illustrated dimensions are exemplary for average sized individuals; it should be understood that these dimensions may be scaled upwardly or downwardly to accommodate much larger or smaller users.

In use, the user simply relaxes onto the new therapeutic cushion as shown in FIGS. 5 and 7 for very short time intervals, which provide a gentle flexion to the entire spine while cradling the head. This flexion allows the spine to gradually realign by curving in the opposite direction to the effects of gravity. The user is instantly exposed to existing postural deficits, while being simultaneously led to a path of recreating the physical stature of the body in a new, simple, and easily sustainable way.

The new and improved therapeutic cushion provides temporary supported flexion or stretch of the seven cervical vertebrae, the twelve thoracic vertebrae, and the five lumbar vertebrae. Depending on the length of the user's spine, a portion of the sacrum (five fused lower vertebrae) may also be supported. The remaining lowest vertebrae section, the coccyx, is typically not supported by the cushion.

The new therapeutic cushion is molded or formed as a unitary dense foam shape having two distinct sections: the head cradle section and the torso support section. If desired, the unitary foam shape may be enveloped with a form-fitting cover fabricated from a soft, light-weight, washable fabric (not illustrated) or overcoated with a protective film (not illustrated).

The apex 31 of the head cradle section serves as a self-informing pivot point for the back of the neck at the base of the skull. This, in turn, dictates the manner in which the lower two main sections of the spine (thoracic and lumbar) will conform to the cushion as the user lays down upon it horizontally. Designed to be contour-fitted for the three upper sections of the spine, the apex initiates proper placement by gently receiving and supporting all seven cervical vertebrae, typically pivoting between C-3 and C-6. This permits the cervical spine to relax completely while initiating proper alignment for the lower sections of the spine.

While the head is supported so as to descend away from the neck and relax into the cradle, the torso is simultaneously supported so as to settle in the opposite direction away from the head and neck. This allows the spine to experience an impulse of a two directional passive traction, soothing the spine into a deeper relaxation than when merely lying flat and unsupported.

All twelve thoracic vertebrae and all five lumbar vertebrae experience a general quality of similarly supported flexion from the gently curved torso section 33 of the cushion. While potential users have different overall spinal lengths as well as differently sized vertebrae, the fundamental support region of this section typically ranges from the 6^th to the 10^th thoracic vertebrae, while the lumbar vertebrae benefit from being generally supported along their entire length.

It should be understood, of course, that the specific form of the invention herein illustrated and described is intended to be representative only, as certain changes may be made therein without departing from the clear teachings of the disclosure.
