BACKGROUND OF THE INVENTION
This invention involves a total back support cushion system and more
particularly involves a device and method which supports the thoracic,
lumbar, and cervical regions of the spine all at one time or in various
combinations.
It is long been recognized that it is desireable to support the entire
person's back when seated or lying down. Most seats and many beds are
totally or inadequately designed to support the person's back over a
period of time. Bolster pillows and cylindrical and semi-cylindrical
lumbar and cervical support cushions have been available for some time.
Some devices are directed to support of the head and the lumbar portion of
the back.
However, persons suffering from low back pain, a muscle injury due to
whiplash or a more serious back condition find that support of a
particular area of the back is insufficient. Some tend to exacerbate a
condition in another portion of the back. A system has been needed for
total back support. None of the devices described above or those available
in the art satisfy these needs nor attain the objects described herein
below.

the cylinder, the results of which are illustrated in FIG. 1. Each cushion
device, for example 12, has four surfaces, namely semi-cylindrical surface
20, semi-circular end surface 22, semi-circular end surface 24 (hidden in
this view) and rectangular surface 26 (mostly hidden in this view).
Likewise cushion device 14 has the same four surfaces, semi-cylindrical
surface 28, semi-circular end surface 30, semi-circular end surface 32
(hidden in this view) and rectangular surface 34 (hidden in this view).
Two strips of hook Velcro fastener strips 36 are sewn or adhesively
attached to end surface 22 of cushion device 12. Loop Velcro fastener
strips 38 are attached to surface 28 of cushion device 14. Strips 38 are
sewn or adhesively attached lengthwise on surface 28 intermediate between
ends 30 and 32, and proximate lengthwise edge 40 which is a juncture
between surface 28 and surface 34 (shown in FIG. 4). Fabric attachment
loop 42 is sewn to cushion device 14 extending from end 32.
In FIG. 2, cushion device 12 is illustrated turned around so that surfaces
24 and 26 may be totally viewed. This configuration of the invention has
semi-circular end surface 24 with no Velcro attachments attached to it. In
other configurations of the invention illustrated later, a Velcro
attachment fastener will be attached on this end as well as the other end
of a cushion device. Hook Velcro strips 44 and 46 are attached to
rectangular surface 26 proximate ends 22 and 24, respectively. Velcro
strips 44 and 46 are both attached longitudinally across the short ends of
the rectangular surface 26. Zipper closure 48 extends along and closes a
slit opening lengthwise down the center a major length of rectangular
surface 26. The position of zipper 48 is close to the position of the
central axis of the cylindrical shape described in FIG. 1.
In FIG. 3, the cross-sectional view shows resilient polymeric foam, such as
polyurethane foam, in semi-cylindrical shape 50 encased in a cloth
covering which includes in this view semi-cylindrical surface 20 and
rectangular surface 26 sewn together with end surfaces 22 and 24 to form
the cloth covering closed by zipper 48.
In FIG. 4 and FIG. 5, cushion device 14 is illustrated. Device 14 viewed
from the opposite side so that rectangular surface 34 is now fully visible
with loop Velcro strips 52 and 54 attached laterally along the short ends
of surface 34 positioned to mate with and fasten to hook Velcro strips 44
and 46 on rectangular surface 26 of cushion device 12 to form the
cylindrical support device illustrated in FIG. 1. Zipper closure 56
extends a major distance centrally lengthwise along surface 34 to allow
removal of semi-cylindrical shaped form core 58 for cleaning the covering
which includes surfaces 34, 30, 32, and 28. Cushion devices 12 and 14 are
constructed to fasten together to form an inverted "T" shape by fastening
together hook Velcro fastener strips 36 with loop Velcro fastener strips
38. Foam core 58 in chosen to be firmer than foam core 50 to provide the
preferred additional support to the lumber region of the back. Similarly,
in FIG. 6, cushion device 16 is fastened at one end with hook Velcro
strips to loop Velcro strips 38 on cushion device 14. Cushion device 16 is
identical to cushion device 12 except that hook Velcro strips 64 are
attached on semi-circular end 62 as well as on the hidden end. Thus,
Velcro strips are attached on both ends of device 16, while Velcro strips
are attached on only one end of cushion device 12. Cushion device 16 has
hook Velcro strips on both ends providing versatility which will be
illustrated below. In the configuration illustrated in FIG. 6, cushion
device 14 is positioned against the lumbar region of the back with
semi-cylindrical surface 60 extending up the spine to support the thoracic
region. As illustrated here, cushions are about 15 inches long, however,
in order to accommodate varying lengths of the spine, the cushions are
provided smaller, about 10 to 12 inches long, and longer, about 18 inches
long. Further, in order to easily identify the firmer foam core
recommended for lumbar support, the covering may be color coded for easy
identification.
In FIG. 7, a side lying "H" shaped back support back device is illustrated
fastening a third cushion device 18 positioned in a horizontal position on
top surface of cushioning device 16 as illustrated in FIG. 6. The term
"side lying" is intended to describe the positioning of the "H" shape
lying on one of its upright sides. Cushion device 18 is equipped with loop
Velcro strips 66 positioned lengthwise on semi-cylindrical surface 68
proximate a lengthwise edge and positioned to attach to hook Velcro strips
64 on end surface 62 of cushion device 16. Cloth loop 70 extends from the
end of cushion device 18 in the same fashion as cloth loop 42. Cloth loop
42 is used as a carrying handle for device 10. It is preferred to provide
lengthwise slits through the covering of either cushion device 12 or
cushion device 16 along the two lengthwise edges joining the rectangular
surface and the semicylindrical surface. The slits being positioned to
allow a strap to be feed through the slits to hold the support device to a
chair back. The use of the device illustrated in FIG. 7 is shown in FIG.
8, where person 78 is sitting in chair 72 with support device 10
supporting the cervical, thoracic and lumbar regions of the back. The
individual cushion devices may be utilized as illustrated in FIG. 9 where
person 74 is supine prone on surface 76 with cervical support provided by
cushion device 18, although cushion devices 12 and 16 would perform in a
like fashion. The lumbar | | |
