Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates to a therapeutic chair. More
particularly, the present invention relates to a therapeutic
recumbent chair that is adjustable for providing support surfaces
to properly support a user's back when in a recumbent position, for
minimizing back problems of a user and for treating back
disorders.
[0003] 2. Description of the Related Art
[0004] As reported by the Cornell University Ergonomics web, "An
estimated 50% of people in the industrialized world suffer some
form of back complaint and many of these are related to poor seat
design." It further notes that the lumbar region of the back is
most often the affected part. Many different configurations of
chairs having back support arrangements have been proposed and
developed. But because of the complexity of the human vertebral
column, few of those chairs, although adjustable, function
sufficiently well to be suitable for providing proper back support,
as well as for treating back disorders.
[0005] The human spine is a complex bony structure that includes
several successive regions having different curvatures when it is
viewed from the side of a standing person. Those regions include
the cervical spine region adjacent to the neck of the person and
that normally has a convex curvature when viewed from the side, and
below it the thoracic region that normally has a concave curvature
when viewed from the side. Below the thoracic region is the lumbar
region, which also normally has a concave curvature, and below the
lumbar region is the sacrum region.
[0006] Most back support devices are configured to provide support
to the lumbar region, because that region is under stress when the
person is in the sitting position. In order to relieve that stress,
good posture is required that serves to dispose the back muscles
and the vertebrae in proper alignment with firm support, or in time
painful back disorders can develop. It is important that the back
support be provided at proper positions of the vertebral
column.
[0007] Another stress point on the back while a person is in the
sitting position are the pressure points associated with the lower
portion of the scapula, which is the bone that defines the shoulder
blade and that connects the upper arm bone, or humerus, with the
collar bone, or clavicle. The scapula is a flat bone, roughly
triangular in shape, and includes an outwardly-projecting region.
The outwardly-projecting regions result in stress on the body when
the person is in a recumbent sitting position. Prior recumbent
seating arrangements provide back support that does not address the
scapular region stress. In instances in which the seating
arrangement includes seat back side edges, or wings, that protrude
forward of the center of the seat back, such as those founds in
automobile seats and some office chairs, cause increased pressure
on the scapula region by cupping the person's back, thereby
resulting in discomfort that could later lead to a back
disorder.
[0008] Prior seating arrangements are generally directed to
treating back conditions, not on preventing them in the first
instance. Persons prone to experiencing back problems would find it
desirable to have an appealing piece of furniture that serves as a
recumbent chair for relaxation, one that helps to prevent back
problems, as well as one to treat back disorders in a comfortable,
convenient, and passive way.
[0009] There is therefore a need for a chair that both prevents
back problems and also treats back disorders when the person is in
a recumbent position.
SUMMARY OF THE INVENTION
[0010] Briefly stated, in accordance with one aspect of the present
invention, an embodiment of a therapeutic chair is provided for
preventing back problems of a user, and also for alleviating back
disorders when the user is in the chair in a static, recumbent
position. The chair includes a frame that can formed from a pair of
parallel side panels supported in spaced relationship by frame
support members that extend between and that are connected with
each of the frame side panels. The frame support members hold the
frame side panels in parallel, laterally spaced relationship.
[0011] As used herein, the term "recumbent" is intended to mean
reclining with the back of the user of the chair oriented at an
angle of from about 10.degree. to about 80.degree. relative to the
plane on which the recumbent chair rests.
[0012] The frame side panels can include respective opposed,
inwardly-extending back cushion support flanges for supporting a
back cushion, and respective opposed, inwardly-extending seat
cushion support flanges for supporting a seat cushion. The back
cushion support flanges are disposed at an obtuse angle relative to
the seat cushion support flanges. A back cushion is connected with
and is supported by the back cushion support flanges, and it
includes a rigid rear surface for supporting the back cushion. A
seat cushion is connected with and is supported by the seat cushion
support flanges and has a rigid lower surface for supporting the
seat cushion.
[0013] In a further embodiment of the invention, a pair of
laterally spaced, substantially horizontally extending, elongated
arm rests can be pivotally connected to and supported by respective
ones of the frame side panels to support a user's arms while the
user is seated in the chair. The arm rests are supported for
limited pivotal movement in an upward and rearward direction to
allow easy access to and egress from the chair. To limit pivotal
movement of the arm rests the frame side panels each include a
respective stop to limit an angular range of pivotal movement of
the arm rests from a first, substantially horizontal position of
the arm rests to a second, upwardly directed position in order to
facilitate entry onto and egress from the chair.
[0014] In a still further embodiment of the invention, a lumbar
adjustment member is positioned within the back cushion for
providing support for the lumbar region of a user who is seated in
the chair. The lumbar adjustment member includes an adjustably
positioned deflecting member positioned within the back cushion for
providing support for the lumbar region of the spine of the user.
The deflecting member has an adjustment member extending outwardly
from a back surface of the back cushion. The adjustment member
includes a series of longitudinally spaced, transversely-extending
apertures for receiving a lumbar region retaining member in one of
the apertures for retaining the adjustment member at a desired
outward extension position relative to the back cushion back
surface to provide a desired degree of lumbar support for a
user.
[0015] In another embodiment of the invention, the chair can
include an overhead grab bar above the back cushion to allow the
user to grasp the grab bar, or, alternatively, to reach underneath
and past the grab bar with the hands for contact with the forearm
so as to use it as a lever point to stretch the user's arms,
shoulders, and back. The grab bar also serves for facilitating a
comfortable alternate recumbent posture wherein the user grasps the
overhead grab bar to maintain a secure position. The grab bar can
also be made adjustable in height in spaced relation with the upper
edge of the back cushion.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0028] Referring now to the drawings in more detail, and initially
to FIGS. 1 to 4, reference numeral 10 generally designates an
embodiment of a therapeutic recumbent chair in the general form of
a chaise lounge. Although illustrated and described herein in the
context of a chaise lounge, it should be appreciated that the
structure and the functional features of the present invention can
also be utilized in other forms of seating arrangements, such as
recliners, automotive seats, and the like.
[0029] Chair 10 includes a frame, which as shown in the drawings
includes a pair of parallel frame side panels 12 that are spaced
from and that face each other. The side frame panels can each be
unitary elements, or, as shown in FIGS. 1 and 3, they can be formed
from a frame back side panel 14 and a frame front side panel 16,
wherein the frame back and frame front side panels are connected
together by a side panel connection member 18 utilizing a plurality
of screws 20, or the like. The two-piece side panel arrangement as
shown facilitates shipping of the several parts of the unassembled
chair in a smaller size shipping container that falls within the
container size limitations of some shipping companies, so that
shipment of unassembled chairs can be made by common carrier rather
than by motor freight.
[0030] As best seen in FIGS. 1 and 4, the frame side panels 12 are
supported in spaced, parallel relationship by a pair of frame
support members 22 that are connected with and that extend between
the frame side panels 12 to maintain them in spaced, parallel
relationship. Each frame support member 22 is a U-shaped, tubular
support member having a diameter of from about 1 in. to about 2 in.
Each frame member has the parallel arms 24 of the U connected to
respective ones of the front and rear frame side panels 14, 16 by
suitable connecting members, such as bolts 26, or the like. The
cross member 28 of the U-shaped support member 22 that extends
between and connects with each of the parallel arms 24 is
uppermost, as shown, and the lower ends of the parallel arms 24 are
each connected to a respective foot 30, shown in FIGS. 1 and 4 as a
disc for distributing the chair load on the floor surface over a
larger area. The frame support member arms 24 are connected to
respective ones of the feet 30 by connecting members, such as
bolts, or the like, that pass through the feet and that can be
received in threaded receptacles (not shown) securely positioned in
the open ends of the tubular arms 24 of the support members 22.
Arms 24 of the front frame support member 22 are connected to
respective ones of the frame front side panels 16 by bolts 26, or
the like, and arms 24 of the rear frame support member 22 are
connected to respective ones of the frame rear side panels 14 by
bolts 26, or the like.
[0031] As best seen in FIG. 3, each of frame side panels 14, 16 has
a linear upper edge 32 from which a flange 34 extends in an inward
direction, so that flanges 34 of each of frame rear side panels 14
face each other and flanges 34 of each of frame front side panels
16 face each other. Flanges 34 provide the support surfaces for
supporting the respective cushions of the chair and include spaced
openings for receiving screws (not shown) for connecting the
cushions to the chair frame.
[0032] Chair 10 includes a back cushion 36 and a leg cushion 38.
Each of cushions 36, 38 includes a rigid back panel 40 (see FIG.
7), a resilient foam body 42 that lies against back panel 40, and
an overlying cover 44. Back panel 40 can be a plywood panel,
resilient foam body 42 can be a resilient foam having a density of
from about 1.5 lb/ft.sup.3 to about 3.5 lb/ft.sup.3, which can be a
polyurethane foam, and a polymeric cover 44 that extends over foam
body 42 and is connected with back panel 40. Polymeric cover 44 can
be a vinyl coated fabric material. Leg cushion 38 includes a
thigh-receiving region 46 adjacent to and inclined relative to back
cushion 36 at an angle of from about 75.degree. to about
130.degree., and a calf-receiving region 48 extending substantially
horizontally outwardly from the outer end of the thigh-receiving
region 46 and defines an angle therewith of between about 5.degree.
and about 45.degree., to provide a comfortable recumbent chair.
[0033] Although the chair frame is illustrated and described herein
as formed from planar side panels interconnected by tubular cross
members, it will be apparent to those skilled in the art that other
forms of frame construction could also be utilized. For example,
elongated angle members can be interconnected to define an open
frame structure to support a back cushion and a leg cushion in the
relative positional arrangement as those cushions are shown in FIG.
1.
[0034] As shown in FIGS. 1 to 3, chair 10 can include an arm rest
50 at each side of the chair. Arm rests 50 are flat panels, which
can be padded if desired, and are connected with frame back side
panel 14 for pivotal movement in a vertical plane. Each of arm
rests 50 is connected to a respective arm rest support member 52,
which can be an L-shaped tubular member as best seen in FIGS. 1 and
3. Arm rest support members 52 each have an upper leg 54 that is
oriented substantially horizontally and is connected with and
underlies arm rest 50 to support it. Arm rest support members 52
each have a lower leg 56 extending at substantially a right angle
relative to upper leg 54 and in a downward direction when arm rest
50 is horizontal, to connect at its outer end with an arm rest
pivot member 58. Arm rest pivot member 58 is pivotally supported
adjacent to the outwardly-facing surface of frame back side panel
14 and is pivotable about a fixed pivot axis provided by a pivot
pin 60 that is connected to and extends outwardly from frame back
side panel 14.
[0035] As shown in FIGS. 5 and 6, a stop pin 62 extends outwardly
from frame back side panel 14 adjacent to and below pivot pin 60.
Arm rest pivot member 58 includes a pair of spaced stop pads 64
that limit the range of pivotal movement of pivot member 58 and
enable the pivot member to pivot about the pivot axis defined by
pivot pin 60 through a desired angle, such as 90.degree. as shown,
but which can be an angle of from about 70.degree. to about
130.degree., at the ends of which pivotal movement range one of
stop pads 64 comes into contact with stop pin 62 to limit the
pivoting of arm rest pivot member 58 and of arm rest 50. The
pivotal movement of one or the other of the arm rests from the
substantially horizontal position shown in FIG. 3 to an elevated
position limited by one of stop pads 64 allows the user to easily
gain access to or to leave chair 10 from the side without being
impeded by arm rest 50.
[0036] FIG. 7 is a longitudinal cross sectional view taken through
the longitudinal center of chair 10 and of cushions 36, 38. As
shown, back cushion 36 includes an inner adjustable lumbar support
member 66 at a position within back cushion 36 corresponding
substantially with the lumbar region of the back of a user when the
user is in a recumbent position in the chair. Lumbar support member
66 is shown in FIG. 8 as a substantially circular flat plate that
is initially in contact with the inner surface of back cushion back
panel 34 to contact the back surface of back cushion 36. Lumbar
support member 66 can be moved inwardly into foam cushion material
42 and toward the outer surface of back cushion 36 to accommodate
the curvature of the lumbar region of the spine of the user, and to
provide the desired degree of lumbar spine support for the user of
the chair. Although lumbar support member 66 is shown as of
circular form and having a flat outer face, it can also be of oval
or elliptical form and can have a convex outer face, if
desired.
[0037] Similarly, back cushion 36 includes an inner, adjustable
scapula region support member 68 at a position within back cushion
36 and spaced upwardly from lumbar support member 66 to lie
opposite the scapula region of the back of a user of chair 10.
Scapula region support member 68 is shown in FIG. 9 as a flat plate
of substantially oval or elliptical form, and is initially in
contact with the inner surface of back cushion back panel 34.
Scapula region support member 68 preferably has its major axis
extending in the longitudinal direction of back cushion 36, and it
can be moved inwardly into the foam cushion material 42 and toward
the outer surface of back cushion 36 to lie opposite to and to
accommodate the upper region of the user's back between the scapula
bones, and to provide the desired degree of additional back support
for the user of the chair.
[0038] As best seen in FIG. 7, each of lumbar support member 66 and
scapula region support member 68 is attached to a respective
adjustment rod 70. Each adjustment rod 70 is connected with the
rearwardly-facing surface of the respective plate, the side that
faces the back cushion support panel, by a respective bolt 72, and
it slidably extends rearwardly through an opening formed in back
cushion back panel 40.
[0039] Each of adjustment rods 70 includes a plurality of
transversely-extending, longitudinally spaced throughbores 74, as
shown in FIG. 10. Adjustment rods 70 pass slidably through an
opening 76 in a respective guide member 78 that is attached to back
panel 40 of back cushion 36 by screws 80, or the like. Each of
guide members 78 includes a narrow throughbore 82 that passes
transversely through guide member 78 and through guide member
opening 76 to receive a cylindrical retaining pin 84 having an
enlarged end or a ring 86. Pin 84 passes through one of
throughbores 74 provided in adjustment rod 70 to lock adjustment
rod 70 and the associated lumbar support member 66 and the
associated scapula region support member 68 in a desired position
spaced from back cushion support panel 40 to provide the desired
degree of back support for the user. The adjustment of each of
lumbar support member 66 and scapula region support member 68 is
effected by removing retaining pin 84 and pushing adjustment rod 70
toward back cushion 36 until the desired position of lumbar support
member 66 and scapula region support member 68 is achieved.
[0040] In addition to the lumbar and scapula region support members
66, 68, and as shown in FIGS. 1 to 4 and 7, chair 10 includes a
pillow 88 that rests against the back cushion and that can be
adjustably positioned along back cushion 36 for supporting the neck
of the user of chair 10. Pillow 88 extends between and within the
outer side ends of back cushion 36 and has a wedge shape when
viewed in transverse cross section. The wedge shape of pillow 88
has a wedge angle defined by the outwardly-facing surfaces of
pillow 88 and of such a magnitude, such as between about
270.degree. and about 225.degree., so that pillow 88 does not
completely fill the area behind the user's neck.
[0041] Adjustment of the position of pillow 88 along the outer
surface of back cushion 36 is effected by a retaining component 90
that is connected with pillow 88 to extend rearwardly of pillow 88
and to pass over and around the upper end of back cushion 36, as
shown in FIG. 11. Retaining component 90 includes a series of pairs
of laterally spaced openings that can contain grommets 92, through
one pair of which openings a pair of screw posts (not shown) that
are located at the back face of back cushion back panel 40 and that
extend outwardly and to which a retaining nut, or the like (not
shown) is applied to secure retaining component 90 when pillow 88
is in the desired position on the surface of back cushion 36.
Retaining component 90 is positioned relative to the upper edge of
back cushion 36 to maintain pillow 88 in the desired position on
the outer face of back cushion 36 for maximum comfort of the
user.
[0042] As can be seen in FIGS. 1-4, chair 10 includes an overhead
grab bar 94 that is supported by and that extends upwardly from and
outwardly of back panel 40 of back cushion 36. Overhead grab bar 94
is a generally U-shaped component that is suitably connected to
back cushion back panel 40, such as by screws, or the like (not
shown), and is provided to allow the user of chair 10 to grasp grab
bar 94 and pull, or to use it as a lever point in contact with the
forearms to stretch the user's arms, shoulder, and back, and for
providing the user with a comfortable, alternate posture with arms
overhead by grasping of bar 94. Overhead grab bar 94 can be a
tubular member having a diameter of from about 1 in. to about 2
in., and including a substantially horizontally-extending bar 96
and a pair of substantially parallel arms 98 that extend from
respective outer ends of horizontally-extending bar 96 and that are
connected to back cushion back panel 40 by screws or the like (not
shown).
[0043] If desired, and also during assembly of the chair
components, the position of back cushion 36 along frame back side
panel 14 can be adjusted by grasping the two back cushion moving
handles 100 shown in FIGS. 4 and 11 and moving back cushion 36 in
the desired direction along flanges 34 of frame back side panel
14.
[0044] Although particular embodiments of the present invention
have been illustrated and described, it will be apparent to those
skilled in the art that various changes and modifications can be
made without departing from the spirit of the present invention.
Accordingly, it is intended to encompass within the appended claims
all such changes and modifications that fall within the scope of
the present invention.
