Description
BACKGROUND
This invention relates to a sleep support system for comfortably
supporting a user during sleep. More particularly, it relates to a
sleep support system for face-down sleep in essentially a sitting
position, for use with at least one support, adapted to support a
user's body so that the user's buttocks and thighs are in an
approximately horizontal position.
A consensus exists within most scientific and medical communities
supporting a correlation between sleep and the health of an
individual. Numerous studies have shown a link between chronic sleep
disruption and poor physical and mental well-being.
The importance of sleep disruption as a public health problem has
been recognized by both national and international groups, including
the World Health Organization. In a 1996 study undertaken by the
World Health Organization, researchers reported that over a quarter
of the 26,000 primary care patients in 15 surveyed countries
experienced chronic sleep disruptions. Individuals recognized as
being most negatively affected by sleep disruption were recovering
patients and individuals with long-term medical conditions. Sleep
disruption in a recovering patient can slow the progress of
recuperation, thereby increasing the risk of complications and
subsequent cost of health care for the patient.
A significant number of medical conditions and procedures require
that patients remain in specific and/or restricted positions during
rest or sleep. Many individuals are limited to sleeping in an
upright position. Physicians, medical practitioners and patients
have known for some time that for many conditions, an upright sleep
position can aid in relieving discomfort, thereby increasing the
duration and quality of sleep. Patients with moderate to advanced
congestive heart failure having pulmonary edema (pooling of fluid in
lungs) find that the resulting dyspnea (difficulty in breathing) is
often relieved by upright sleep. Burn patients and patients with
injuries to the back of the body often use an upright sleep position
to manage pain. Other common conditions that benefit from upright
sleep include gastro esophageal reflux disorder (backward flow up
into the esophagus of acidic stomach contents) and obstructive sleep
apnea syndrome (periodic short term blockage of the airway during
sleep).
Standard patient recovery rooms are characteristically equipped with
an adjustable bed and a rolling over-bed table. Most standard
adjustable hospital beds are designed to provide a limited range of
user positioning. Typically, the upper supporting portion of the bed
may be raised to an inclined position of less than 90 degrees.
Limited bed adjustability forces most upright sleeping patients and
attending staff to improvise makeshift upright sleep supports using
pillows and blankets.
Based on the above discussion, it is clear that many individuals
could benefit from a system designed to facilitate comfortable
upright sleep. Introduction of a relatively inexpensive system would
allow both inpatient health care providers, and home-based
caregivers, the greatest flexibility in providing upright sleep
support systems to patient recovery rooms. In addition, the need
exists for a lightweight portable system that will allow for set-up
and removal by any attending patient-care staff member or home-care
individual. Further, a need exists for a system that provides a
compact design that can utilize existing furnishings, fixtures and
equipment for primary support, limiting the impact to individual
patient space and storage requirements.
OBJECTS OF THE INVENTION
A primary object and feature of the present invention is to provide
a system for upright sleep. It is a further object and feature of
the present invention to provide such a system that is lightweight,
portable (easy to manipulate, hold and transport). It is an
additional object and feature of the present invention to provide
such a system that is simple to use and is adjustable to a wide
range of user-selected positions. It is a further object and feature
of the present invention to provide such a system that may be
mounted to a secondary support fixture, such as an over-bed table or
wheelchair. Additionally, it is an object and feature of the present
invention to provide such a system that is foldable into a compact
form that is easily stowed. It is a further object and feature of
the present invention to provide such a system that is easy to
manufacture, assemble and service.
A further primary object and feature of the present invention is to
provide such a system that is efficient, inexpensive, and handy.
Other objects and features of this invention will become apparent
with reference to the following descriptions.

118 is pivotally joined to the base panel 116 with at least one
hinge 120 (herein embodying an angle connection structured and
arranged to connect such at least one lower support member at an
acute angle with such at least one upper support member), allowing
the upper panel 118 and attached arm support assembly(ies) 110 to
rotate about an axis 128. Preferably, the hinge 120 (herein
embodying at least one clamp structured and arranged to secure such
at least one intermediate support to at least one primary support)
is a commercially available butt-type hinge, preferably constructed
of stainless steel. Preferably, the hinge is recessed into the lower
surface 130 of the upper panel 118 and upper surface 131 of the base
panel 116 to allow the two panels to fold fully flat (as further
illustrated in FIG. 11). The hinge 120 is preferably fastened to the
upper panel 118 and lower panel 116 permanently (e.g., by adhesives,
welding, rivets, or similar fasteners appropriate to the substrate)
or semi-permanently (e.g., with screws, or nuts and bolts or similar
fasteners appropriate to the substrate). Under appropriate
circumstances, in consideration of cost and ease of assembly, the
hinging mechanism may be integrally formed with the upper panel 118
and lower panel 116. FIG. 3 illustrates an embodiment of the present
invention utilizing at least one adjustable clamp 125, preferably

132, into a threaded aperture 138 located in the upper surface 131
of the base panel 116 (also shown in FIG. 8). Preferably, this
allows the "C" shaped bracket 132 to adjustably slide along the
threaded shaft 137 of the clamping knob 136 within the length of the
elongated slot aperture 134. Preferably, the position of the bracket
132 is set when the clamping knob 136 is tightened, firmly securing
the bracket 132 by friction, against upper surface 131 of the base
panel 116. This adjustment preferably accommodates any variations in
the width of the secondary support fixture. Preferably, a second
clamping knob 142 is provided at the "C" shaped bracket 132 (visible

assembly 110 is covered with a resilient pad comprised of a
deformable elastic material (preferably foam rubber or urethane
foam) with a washable outer covering (preferably, vinyl or similar)
that is sewn or formed to encapsulate the underlying elastic
material. Under appropriate circumstances, the interior body 150 and
resilient pad may be produced as a single composite assembly.
Preferably, a second outer cover 152 (herein embodying at least one
upper portion of such at least one arm support comprising at least
one arm-support surface structured and arranged to be cleanable and
moisture-permeable, such at least one arm-support surface portion
adapted to contact at least one portion of the user's arm during
face-down sleep) comprising a soft, cleanable and moisture-permeable
material, such as fabric, lambs wool (or similar), is removably
fastened over the resilient pad with hook and loop straps or snaps.
Preferably, this second outer cover 152 serves as the surface in

the arm support assembly 110 is free to rotate about an axis 158, a
pivot point set by the position of the threaded shaft 155, part of
clamping knob 152 (herein embodying at least one
arm-coplanar-position adjuster structured and arranged to provide
coplanar position adjustment of such at least one arm support), as
shown. This adjustment preferably accommodates the natural planar
rotation of the arm toward and away from the midline of the body at
the elbow (planar abduction/adduction). Preferably, the arm support
assembly 110 is selectively movable laterally (relative to the
central symmetry line of both the device and user) along the length
of the slot aperture 156, as shown. This lateral adjustment feature
is designed to accommodate the natural planar movement of the arm
about the shoulder joint, as well as providing shoulder width
adjustment to fit various sized users. Preferably, the position of
the arm support assembly 110 is set when the clamping knob 154
(herein embodying at least one retainer, structured and arranged to
retain such at least one arm-coplanar-position adjuster in a
selected position) is tightened, firmly securing the arm support
assembly 110 by friction, against upper surface 160 of the upper
panel 118. Under appropriate circumstances, other methods of
attaching and selectively positioning the arm support assembly 110
may suffice. Preferably, the sleep support system 100 further
comprises at least one angle adjusting mechanism 122 for adjusting

inches (30.48 cm), as shown. Under appropriate circumstances, other
opening configurations may suffice. In the preferred embodiment, two
symmetrically located hinge(s) 120 are approximately centered
between the outer edge of the upper panel 118 and inner edge of the
"U" shaped peripheral opening 172, as shown.
FIG. 5 is a side elevational view of the sleep support system. In
FIG. 5, the relative thickness of the upper panel 118 and lower
panel 116 are visible. Preferably, the thickness of both the upper
panel 118 and lower panel 116 is about 3/4 inch (1.91 cm). Also
shown in FIG. 5 is the slightly tapered profile of the arm support
assembly 110. Preferably, the thickness of the arm support assembly
110 increases from the lower forearm-supporting portion 173 to the
upper gripping-portion 174, allowing the user to grasp the upper
portion of the arm support assembly 110 without impinging on the
upper panel 118. To accommodate a range of user arm lengths, the arm
support assembly 110 is preferably constructed, in at least two
parts, with at least one first arm support segment 140, slidably
engaging at least one second arm support segment 141 (in a
telescopic fashion), as shown.
Preferably, at least one spring lock 144 (e.g., a spring-loaded push
button engaging a retaining indentation or hole) that is set and
released by hand action by the user is provided to adjust and fix
the position of the first arm support segment 140 relative to the
second arm support segment 141, as shown. Preferably, by releasing
the spring lock 144 from the retaining indentation 146 and
telescopically sliding the second arm support segment 141 relative
to the first arm support segment 140, the overall length of the arm
support assembly 110 may be adjusted. Preferably, four retaining
indentation(s) 146 are shown, generally located along the outer
sides of the arm support assembly(ies) 110 to allow for convenient
user access. Other quantities of retaining indentation(s) 146 are
within the scope of the invention. Additional arm support assembly
length adjustments can be provided, for example, by means of
additional retaining indentation(s) 146. Those skilled in the art
will appreciate that, under appropriate circumstances, other
arrangements for releasably locking the arm support segments may
suffice. Preferably, the average length of the arm support assembly
110 is about 18 inches (45.72 cm).
Preferably, the sleep support system 100 further comprises at least
one angle adjusting mechanism 122 for adjusting the upper panel 118
angle of inclination relative to the base panel 116, as shown.
Preferably, the upper panel 118 can be lifted and locked in an
infinite number of selected positions between the raised position
and the lowered position. The preferred range of angular adjustment
for the upper panel 118, about an axis 128, is between about 0 and
about 90 degrees. Preferably, the angle adjusting mechanism 122
comprises at least one first strut 162, with at least one proximal
end pivotally mounted to the base panel, and at least one second
strut 164, with at least one proximal end pivotally mounted to the
upper panel, as shown. Preferably, distal ends of the first strut
162 and second strut 164 loosely engage at least one clamping knob
166 having a threaded shaft 167 and at least one receiver plate 168
having a corresponding threaded aperture 170. With the clamping knob
166 disengaged, the first strut 162 and second strut 164 are free to
pivot about the axis of the threaded shaft 167. By tightening the
clamping knob 166 (herein embodying at least one retainer,
structured and arranged to retain such at least one
arm-incline-position adjuster in a selected position), the receiver
plate 168 is drawn tightly against the first strut 162 and second
strut 164, thereby rigidly locking the assembly, by friction, at a
selected angle (simultaneously fixing the relative positions of the
upper panel 118 and base panel 116). Under appropriate
circumstances, other methods of selectively setting the angle of
inclination of the upper panel 118 may suffice. As an example, each
distal end of both first strut 162 and second strut 164 may further
comprise an opposing set of radially positioned teeth that, when
meshed, prevent pivotal movement of the first strut 162 and second
strut 164 about the longitudinal axis of the threaded shaft 167.
FIG. 6 is a sectional view, through section 6--6 of FIG. 4,

lockable pivot joint 200 has a locking/releasing mechanism,
preferably comprising at least one clamping knob 202 (herein
embodying at least one retainer, structured and arranged to retain
such at least one face-incline-position adjuster in a selected
position) having a threaded shaft 203, that when tightened, firmly
secures the pivot joint 200 at a preferred angle, preventing
movement when the resting weight of the user is applied to the head
support assembly 110. Preferably, the pivot joint(s) 200 operate on
a friction retention basis, allowing an infinite number of selected
positions within its range of movement. Preferably, the three arm
segments 198 are each threadably attached to its neighboring
structure. Preferably, the first arm segment 204 (preferably
constructed from a hollow rigid plastic, aluminum or stainless steel
tube) is threaded to the swivel body 192, and to a first lockable
pivot joint 206, as shown. Preferably, the length of the first arm
segment 204 is about 1 inch (2.54 cm). Preferably, a second lockable

desired position. Under appropriate circumstances, mechanical and
electro-mechanical actuators may be used to operate the various
adjustable components of the sleep support system, including the
inner gear 248, without exceeding the scope of the present
invention. Those skilled in the art will appreciate that the use of
electric drive motors with various types of transmission and linkage
elements, including gear and screw drives, are well-known in the art
and may be used to cause relative movement between portions of the
sleep support system. Under appropriate circumstances,
electromechanical, hydraulic, all types (including any combination
of the above-noted elements) may be utilized for adjusting portions
of the sleep support system.
FIG. 12 is a side elevational view of the sleep support system 100
