Description
2120~39 HINGED NON-ELASTIC INSULATEb BACK SUPPORT
Field of the Invention This invention relates in general to back support devices and more particularly to a hinged, non-elastic in~ul~tçd back support.
R~-~ground of the Invention A wide variety of back support devices are known, inçlu-ling therapeutic or orthopaedic devices, weight lifting support belts, or belts used to protect the lower spine during exertion or lifting.
In order for such devices to permit the wearer to move freely, the devices are typically dç~ignçd to be either narrow belts of non-elastic m~t~ri~l which span the waist area only (and ll,~erore provide limited restriction on movement due to the width of the belt) or are el~tici7~d devices which may be six to twelve inches in width and which confol,l, to the body much like a girdle. The latter usually incol~ldle sel)~ale panels or vertical riWing in the back portions of the devices to aid in ~ o,ling the back of the persons wearing the devices, while permitting the movement of the w~,~ due to the el~ti~-i7~ portions of the belts.
An ~l~e. ~ ive approach is shown in U.S. patent 5,046,488, granted September 10, 1991 to James W. Schiek, Sr. entitled Support Belt for the T.umb~r Vertebrae.
The Schiek patent di~loses a support belt comprising a unitary structure of pliable, non-elastic m~tPri~l and having a back section for sp~nning the lumbar vertebrae with strap means eYt~n~ing obliquely from the back section to form a belt. The belt of the Schiek patent is described as defining a tapered, tr~m~ted, conical belt, having a larger ~ eler at the top than at the bottom. This tapered conical shape is accompli~hed by having the straps of the belt extend obliquely in dowllw~d direction from the back section of the belt. The Schiek patent discloses a belt designed to provide a ~tisf~ctory co~h~ on the back muscul~t~lre for those lifting weights in sport or in the course of an occ.,p~;on. The average width of the widest section of the belt is defined to be 3" to 6". Thus the belt is similar to a narrow weight-lifting belt.
The belt disclosed in the Schiek patent does not address the issue of providing heat to the wearer's back, nor does it in~ t~ that the inco,~,~lion of the downward 2i20~39 sloping straps, and the use of a conical shape may not provide a firm fit of the back support for all body shapes. For some body types, especially the body type of certain women, the dowllw~dly sloping straps prevent a close fit.
The dirrelences in body shape belwæn men and women are addressed in C.~n~ n patent applic~tion 2,069,276, naming James A. Gregory as inventor and applicant, and entitled Woman's Cross-Training Sport Support Belt. In the Gregory appli~tion, a support belt having a lumbar support section is disclosed. Side support sections have concave lower edges in order to colltour over the hips of the wearer.
The belt does not address the need to provide heat to the wearer, neither does it li~losP~ the need to angle the side portions of the belt relative to the back portion, for some w~e~s.
Also known in the art are heat ret~ining belts to provide heat therapy for the back and which include a support function. These belts do not, however, have a design which enables the belt to be firmly placed over the area to be treated, while pellllitlii g freedom of movement of the user of the belt.
The belts described above also are generally ch~ t~ri7~d by having a single point at which the belt is tigl~tPnf~l or 1Oo3elled by the wearer.
Thus a back support device which is of a non-elastic m~teri~l to provide support for the back, and which is in~ul~t~ to provide heat to the back, which fits wears of dirf~,nt body types snugly to permit support and e~reclive retention of heat, and which may be adjusted at more than one point on the device, is desirable.
Su"""a,~ of the Invention An object of one aspect of the present invention is to provide an improved back support device.
In accor~ce with one aspect of the present invention there is provided a back support device comprising a flexible, non-elastic back support portion comprising an g layer and having first and second ends, a first abdominal panel comprising first hinge conn~tin~ means for connP~l;ng the first abdo,l,illal panel to the first end of the back support portion, a second abdominal panel comprising second hinge conn~l;ng means for conn~ting the second abdominal panel to the second end of the back support portion, and a means for f~tPning the first abdominal panel to the .
second abdomina~ panel.
In accordance with a further aspect of the invention the first and second hinge connecting means further comprise means for adjusting the distance between the back support portion and the first and second abdominal panels, respectively.
In accordance with a further aspect of the invention, there is provided a back support device fitted for a wearer comprising a flexible, non-elastic back support portion having a support radius section and first and second ends, a first abdominal panel hingedly connP~te~ to the first end of the back support portion, and having a longitu-lin~l axis, a second abdominal panel hingedly connected to the second end of the back support portion, and having a longit~1-1in~1 axis, a means for fastening the first abdominal panel to the second abdominal panel, wherein the back support portion comprises an in~ul~tor for lc;l;~inil-g body heat of the wearer when the device is worn, the back support panel, the first and second abdominal panels and the means for f~tening are configured to permit the device to be f~tPnPd encircling the girth of the wearer in a generally cylin~lric~l manner, such that the means for fastening lies in a horizontal plane with the support radius section, so as to cause a force to be evenly applied to the back support portion to bring the back support portion to bear firmly against the lower lumbar and upper sacrum region of the wearer's back.
Advantages of the present invention are that the support provided by a non-elastic device, and the benefit of the retention of body heat over the lower lumbar and upper sacrum region of the back are provided by the firm placement of the back support against the back made possible by the variable oriPnt~tion of the closure portions of the device relative to the support radius section of the back support. The hinged abdominal panels pivot up or down, to permit the belt to be adjusted to closely fit different body types.
By ret~ining body heat in the lower back, m~ s and lig~m~nt~ around the lower vt;l~e~l~e and upper sacrum are kept warm to aid in prevention of strain and hair line cracking.
A further advantage of the present invention is that the belt may be adjusted at more than one point on the belt. Additional press~lre may be applied to the lumbar area with minim~l pull being applied to the abdominal area of the person wearing the belt. Co,lv~l~ly, the panels of the belt desi~nKI to be worn over the abdomen are 21~0539 able to be tightpn~d with minim~l pull being applied to the back section.

Detailed DescliL.lion of the Plc;f~ d Embodiment Referring to Figure 1, there is illustrated in an elevational view, a back support device 18 in accoLdallce with a pl~rellPd embodiment of the present 212~39 invention. The back support device incl~ldes a back support panel 20, abdominal panels 22, 24, a strap 26 and a D-ring 28. The strap 26 has velcro portions 30 and 32 affixed to the strap 26 such that when the strap 26 is introduced in the D-ring 28 it may be looped back upon itself to allow the velcro portions 30 and 32 to secure the 5 strap.
Figure 1 also shows the hinges 33, 34 having D-rings 35, 36, respectively.
D-ring 35 is ~tt~rh~ to back support panel 20 by strap 38. D-ring 36 is ~tt~rh~d to back support panel 20 by strap 40. Straps 38, 40 are ~tt~rh~ to back panel 20 bystitching and by eyelets 42, 44, whose role is largely deco.~tive.
D-ring 28 is ~tt~h~ to abdominal panel 24 by strap 45 which is sewn onto panel 24. Ends 46, 48 of straps 26, 45 are looped through D-rings 35, 36, ively. The ends 46, 48 are secured to straps 26, 45 by velcro. Although these ends of the belt are secured in a non-p~ nt fashion in the p~fer-~d embodiment of the invention shown in Figure 1, the ends may also be perm~n~ntly secured to the D-rings, if desired. Such a ~ n~ ",.~n~ does not, however, permit the adj~lstm~nt of the belt by the wearer to provide more or less abdominal or back support. Pulling both straps eimlllhneou~ly permits regulation of the p~ess. le applied against the back se~tion, as .~ui~. The use of velcro to secure the ends enablesthe belt to be more adjustable than is the case if the ends are perm~n~ntly secured.
In Figure 2, the back support device of Figure 1 is shown in cross-section along the line 2-2. The panel 20 has trim 48 which is shown at either edge of the back support portion of the device. The device is shown as having a sandwich construction with an inner layer 60 of a high density vinyl or rubber providing an in~ tion layer, a layer 64 of woven or knitted inner facing fabric of the lycra or similar wicking ch~r~ct~-rietics and a layer 62 of nylon, polyester or acrylic fabric.
The trim 48 is stitched to the panel 20. Both panels 22, 24 have the same sandwich construction with trim ~th~h~ in the same ~ . In the p-~fe,l~d embodiment the panels are suffic1ently thin to permit the straps 26, 45 to be sewn onto the panels and the stit~hing to pass through the three layers of the panels.
In Figure 3, the back support device of Figure 1 is ill~str~ted in a side elevational partial broken away view in position on a wearer, with the vertebrae of - ~120~3~
the wearer shown. The back support panel 20 of the device is shown in position ~jal,Pnt to the ~ de of the lumbar and upper sacrum region of the wearer's back.The abdominal panel 22 is adjusted by way of the hinge 33 so that the support device 18 does not overly either the iliac crest or the ribs of the wearer (not shown). Shaded 5 region 74 coll~s~n~l~ to the support radius of the back support.
In Figure 4a, the back support device of the prerGllGd embodiment is shown in a schPm~tic lepl~- ,I~;Qn in position on a male wearer of average body type with a height/weight ratio of 3.0 pounds per inch or less. Figure 4b shows the support device of Figure 4a in s~ t;c lG~ ~nl~;on illustrating the relative positions ofpanel 20 and panels 22. As is shown in Figure 4a, and more particularly in Figure 4b, an im~in~ry line belwGen the D-ring 28 and the support radius 74 is approxim~tely ho, ;,~nl~l. The panel 20 of the device is therefore subject to a direct horizontal force pulling the panel into contact with the back of the wearer. The~imt~n~ion~ of the panel 22 ensures that there is support for the abdomen of thewearer while pGl~ Ling ease of movement by riding above the iliac crest and below the ribs. The panel 20 provides heat ret~ntion and support for the lower lumbar and upper sacrum regions of the wearer's back.
In Figure Sa, the back support device of the pfere~lcd embotlim~nt is shown in position on a male wearer of a mature figure body type with a heightlweight ratio of greater than 3.0 pounds per inch. Figure 5 shows the support device of Figure 5a in scl~n~;c ~epl~s~-,L~;on illll~tr~tin~ the relative position~ of panel 20 and panels 22. As is shown in Figure Sa, and more particularly in Figure Sb, in this case, an im~in~ry line bel~ the D-ring 28 and the support radius 74 is remains horizontal.
The panel 20 of the device is therefore subject to a direct horizontal force pulling the panel into contact with the back of the wearer. This is despite the fact that the hinge 33 of the device enables the strap 26 to angle dowllw~dly from the back of the wearer to the D-ring 28. The hinge permits the device to ride below the widest part of the abdomen of the wearer having this body type. This is the most comfortableposition for the wearer.
The tlim~n~ions of the panel 22 and the location of the hinge 33 ensure that there is sup~ort for the abdomen of the wearer while pft",iLI;ng ease of movement by riding above the iliac crest and below the ribs. The panel 20 provides heat retention and support for the lower lumbar and upper sacrum regions of the wearer's back.
In Figure 6a, the back support device of the plcfcllcd embodiment is shown in position on a female wearer having an average body type with a heightlweight ratio of 2.5 pounds per inch or less. Figure 6b shows the support device of Figure 6a in schem~tic lcpre~n~ ;on i1111~t~ting the relative positions of panel 20 and panels 22.
As is shown in Figure 6a, and more particularly in Figure 6b, in this case, the strap 26 remains much as is the case with the device as shown in Figure 4. Again the belt rides above the iliac crest and below the ribs. There is a h- ri7nnt~1 im~gin~ry line belwæn the D-ring 38 and the support radius 74.
In Figure 7a, the back support device of the plcr~l~d embodiment is shown in position on a female wearer having a full figure body type with a height/weight ratio more than 2.5 pounds per inch. Figure 7b shows the support device of Figure 7a in sch~ c lG~ n~ n i11l.~h~l;ng the relative po~itionc of panel 20 and panels22. As is shown in Figure 7a, and more particularly in Figure 7b, in this case, an im~in~ry line belwæ,~ the D-ring 28 and the support radius 74 is remains horizontal.
The panel 20 of the device is th~crolc subject to a direct hori7Ont~1 force pulling the panel into contact with the back of the wearer. This is despite the fact that the hinge 33 of the device enables the strap 26 to angle upwardly from the back of the wearer to the D-ring 28. As is the case with the body types illustrated in Figures 4, 5, 6, the hinge 33 in Figure 7a permits the device to ride above the widest part of the hip of the wearer having this body type. This is the most co"lfol~ble position for the wearer.
The ~iim~onsion~ of the panel 22 and the location of the hinge 33 ensure that there is support for the abdomen of the wearer while pe~n~ ;ng ease of movement by riding above the iliac crest and below the ribs. The panel 20 provides heat retention and support for the lower lumbar and upper sacrum regions of the wearer's back.
In use, the back support device of the invention is worn about the waist area as shown in Figures 4-7b. The back support panel 20 is placcd over the lower lumbar and upper sacrum of the wearer's back. The abdominal panels 22, 24 are then brought around the side of the wearer and the strap introduced into D-ring 28 and pulled tight. If n~es~.y, ends 46, 48 can be adjusted in D-rings 35, 36. Thewearer will adjust the device so that it rides co---follably on his or her body. As is shown in Figures 3-7b, the positioning of the belt will vary depen-ling on the girth of the wearer.
S By sizing the abdominal panels 22, 24 a~pr~lialely, and by providing hinges 33, 34, the r~ .g of the device to encircle the girth of the wearer brings the back support portion of the device into firm contact with the lumbar and upper sacrumregion of the back. The non-elastic nature of the back support device provides support for the lumbar and upper sacrum region of the back while the siæ and shape of the panels 20, 22, 24 and the arrangement of hinges 33, 34 ensure that a snug fit may be ob~i ed for Weale,l~ having dirrertnt body types despite the non-elastic nature of the device. The ...~ n~nc~ of a snug fit assists in both support for the back and the abdominal m~ s, and for the re~ntion of heat, both of which assist in the pl~ ion of injuries to the back and the abdominal m~lsrles.
Adjllstmen~ of the belt is possible such that the pr~s~ule against the back region may be indep~n-l~ntly adjusted in co---p~ on with the pl~;SSUle, against the abdomen. Straps 46, 48 may be pulled tighter or loosened through D-rings 35, 36 in order to apply more or less pr~s~u,e to the back by way of panel 20.
;v~ly~ strap 26 may be tig~ n~d or loosen~d through D-ring 28 to put more or less pless.lle on the abdomen (the stomach region) by way of abdominal panels 22, 24.
Other v~riqtion~ and mo~ifir~tions of the invention are possible. All such mo~ifir~tion~ or v~ri~ti~n~ are believed to be within the sphere and scope of the invention as defined by the claims appended hereto.
Field of the Invention This invention relates in general to back support devices and more particularly to a hinged, non-elastic in~ul~tçd back support.
R~-~ground of the Invention A wide variety of back support devices are known, inçlu-ling therapeutic or orthopaedic devices, weight lifting support belts, or belts used to protect the lower spine during exertion or lifting.
In order for such devices to permit the wearer to move freely, the devices are typically dç~ignçd to be either narrow belts of non-elastic m~t~ri~l which span the waist area only (and ll,~erore provide limited restriction on movement due to the width of the belt) or are el~tici7~d devices which may be six to twelve inches in width and which confol,l, to the body much like a girdle. The latter usually incol~ldle sel)~ale panels or vertical riWing in the back portions of the devices to aid in ~ o,ling the back of the persons wearing the devices, while permitting the movement of the w~,~ due to the el~ti~-i7~ portions of the belts.
An ~l~e. ~ ive approach is shown in U.S. patent 5,046,488, granted September 10, 1991 to James W. Schiek, Sr. entitled Support Belt for the T.umb~r Vertebrae.
The Schiek patent di~loses a support belt comprising a unitary structure of pliable, non-elastic m~tPri~l and having a back section for sp~nning the lumbar vertebrae with strap means eYt~n~ing obliquely from the back section to form a belt. The belt of the Schiek patent is described as defining a tapered, tr~m~ted, conical belt, having a larger ~ eler at the top than at the bottom. This tapered conical shape is accompli~hed by having the straps of the belt extend obliquely in dowllw~d direction from the back section of the belt. The Schiek patent discloses a belt designed to provide a ~tisf~ctory co~h~ on the back muscul~t~lre for those lifting weights in sport or in the course of an occ.,p~;on. The average width of the widest section of the belt is defined to be 3" to 6". Thus the belt is similar to a narrow weight-lifting belt.
The belt disclosed in the Schiek patent does not address the issue of providing heat to the wearer's back, nor does it in~ t~ that the inco,~,~lion of the downward 2i20~39 sloping straps, and the use of a conical shape may not provide a firm fit of the back support for all body shapes. For some body types, especially the body type of certain women, the dowllw~dly sloping straps prevent a close fit.
The dirrelences in body shape belwæn men and women are addressed in C.~n~ n patent applic~tion 2,069,276, naming James A. Gregory as inventor and applicant, and entitled Woman's Cross-Training Sport Support Belt. In the Gregory appli~tion, a support belt having a lumbar support section is disclosed. Side support sections have concave lower edges in order to colltour over the hips of the wearer.
The belt does not address the need to provide heat to the wearer, neither does it li~losP~ the need to angle the side portions of the belt relative to the back portion, for some w~e~s.
Also known in the art are heat ret~ining belts to provide heat therapy for the back and which include a support function. These belts do not, however, have a design which enables the belt to be firmly placed over the area to be treated, while pellllitlii g freedom of movement of the user of the belt.
The belts described above also are generally ch~ t~ri7~d by having a single point at which the belt is tigl~tPnf~l or 1Oo3elled by the wearer.
Thus a back support device which is of a non-elastic m~teri~l to provide support for the back, and which is in~ul~t~ to provide heat to the back, which fits wears of dirf~,nt body types snugly to permit support and e~reclive retention of heat, and which may be adjusted at more than one point on the device, is desirable.
Su"""a,~ of the Invention An object of one aspect of the present invention is to provide an improved back support device.
In accor~ce with one aspect of the present invention there is provided a back support device comprising a flexible, non-elastic back support portion comprising an g layer and having first and second ends, a first abdominal panel comprising first hinge conn~tin~ means for connP~l;ng the first abdo,l,illal panel to the first end of the back support portion, a second abdominal panel comprising second hinge conn~l;ng means for conn~ting the second abdominal panel to the second end of the back support portion, and a means for f~tPning the first abdominal panel to the .
second abdomina~ panel.
In accordance with a further aspect of the invention the first and second hinge connecting means further comprise means for adjusting the distance between the back support portion and the first and second abdominal panels, respectively.
In accordance with a further aspect of the invention, there is provided a back support device fitted for a wearer comprising a flexible, non-elastic back support portion having a support radius section and first and second ends, a first abdominal panel hingedly connP~te~ to the first end of the back support portion, and having a longitu-lin~l axis, a second abdominal panel hingedly connected to the second end of the back support portion, and having a longit~1-1in~1 axis, a means for fastening the first abdominal panel to the second abdominal panel, wherein the back support portion comprises an in~ul~tor for lc;l;~inil-g body heat of the wearer when the device is worn, the back support panel, the first and second abdominal panels and the means for f~tening are configured to permit the device to be f~tPnPd encircling the girth of the wearer in a generally cylin~lric~l manner, such that the means for fastening lies in a horizontal plane with the support radius section, so as to cause a force to be evenly applied to the back support portion to bring the back support portion to bear firmly against the lower lumbar and upper sacrum region of the wearer's back.
Advantages of the present invention are that the support provided by a non-elastic device, and the benefit of the retention of body heat over the lower lumbar and upper sacrum region of the back are provided by the firm placement of the back support against the back made possible by the variable oriPnt~tion of the closure portions of the device relative to the support radius section of the back support. The hinged abdominal panels pivot up or down, to permit the belt to be adjusted to closely fit different body types.
By ret~ining body heat in the lower back, m~ s and lig~m~nt~ around the lower vt;l~e~l~e and upper sacrum are kept warm to aid in prevention of strain and hair line cracking.
A further advantage of the present invention is that the belt may be adjusted at more than one point on the belt. Additional press~lre may be applied to the lumbar area with minim~l pull being applied to the abdominal area of the person wearing the belt. Co,lv~l~ly, the panels of the belt desi~nKI to be worn over the abdomen are 21~0539 able to be tightpn~d with minim~l pull being applied to the back section.

The back support device incl~ldes a back support panel 20, abdominal panels 22, 24, a strap 26 and a D-ring 28. The strap 26 has velcro portions 30 and 32 affixed to the strap 26 such that when the strap 26 is introduced in the D-ring 28 it may be looped back upon itself to allow the velcro portions 30 and 32 to secure the 5 strap.
Figure 1 also shows the hinges 33, 34 having D-rings 35, 36, respectively.
D-ring 35 is ~tt~rh~ to back support panel 20 by strap 38. D-ring 36 is ~tt~rh~d to back support panel 20 by strap 40. Straps 38, 40 are ~tt~rh~ to back panel 20 bystitching and by eyelets 42, 44, whose role is largely deco.~tive.
D-ring 28 is ~tt~h~ to abdominal panel 24 by strap 45 which is sewn onto panel 24. Ends 46, 48 of straps 26, 45 are looped through D-rings 35, 36, ively. The ends 46, 48 are secured to straps 26, 45 by velcro. Although these ends of the belt are secured in a non-p~ nt fashion in the p~fer-~d embodiment of the invention shown in Figure 1, the ends may also be perm~n~ntly secured to the D-rings, if desired. Such a ~ n~ ",.~n~ does not, however, permit the adj~lstm~nt of the belt by the wearer to provide more or less abdominal or back support. Pulling both straps eimlllhneou~ly permits regulation of the p~ess. le applied against the back se~tion, as .~ui~. The use of velcro to secure the ends enablesthe belt to be more adjustable than is the case if the ends are perm~n~ntly secured.
In Figure 2, the back support device of Figure 1 is shown in cross-section along the line 2-2. The panel 20 has trim 48 which is shown at either edge of the back support portion of the device. The device is shown as having a sandwich construction with an inner layer 60 of a high density vinyl or rubber providing an in~ tion layer, a layer 64 of woven or knitted inner facing fabric of the lycra or similar wicking ch~r~ct~-rietics and a layer 62 of nylon, polyester or acrylic fabric.
The trim 48 is stitched to the panel 20. Both panels 22, 24 have the same sandwich construction with trim ~th~h~ in the same ~ . In the p-~fe,l~d embodiment the panels are suffic1ently thin to permit the straps 26, 45 to be sewn onto the panels and the stit~hing to pass through the three layers of the panels.
In Figure 3, the back support device of Figure 1 is ill~str~ted in a side elevational partial broken away view in position on a wearer, with the vertebrae of - ~120~3~
the wearer shown. The back support panel 20 of the device is shown in position ~jal,Pnt to the ~ de of the lumbar and upper sacrum region of the wearer's back.The abdominal panel 22 is adjusted by way of the hinge 33 so that the support device 18 does not overly either the iliac crest or the ribs of the wearer (not shown). Shaded 5 region 74 coll~s~n~l~ to the support radius of the back support.
In Figure 4a, the back support device of the prerGllGd embodiment is shown in a schPm~tic lepl~- ,I~;Qn in position on a male wearer of average body type with a height/weight ratio of 3.0 pounds per inch or less. Figure 4b shows the support device of Figure 4a in s~ t;c lG~ ~nl~;on illustrating the relative positions ofpanel 20 and panels 22. As is shown in Figure 4a, and more particularly in Figure 4b, an im~in~ry line belwGen the D-ring 28 and the support radius 74 is approxim~tely ho, ;,~nl~l. The panel 20 of the device is therefore subject to a direct horizontal force pulling the panel into contact with the back of the wearer. The~imt~n~ion~ of the panel 22 ensures that there is support for the abdomen of thewearer while pGl~ Ling ease of movement by riding above the iliac crest and below the ribs. The panel 20 provides heat ret~ntion and support for the lower lumbar and upper sacrum regions of the wearer's back.
In Figure Sa, the back support device of the pfere~lcd embotlim~nt is shown in position on a male wearer of a mature figure body type with a heightlweight ratio of greater than 3.0 pounds per inch. Figure 5 shows the support device of Figure 5a in scl~n~;c ~epl~s~-,L~;on illll~tr~tin~ the relative position~ of panel 20 and panels 22. As is shown in Figure Sa, and more particularly in Figure Sb, in this case, an im~in~ry line bel~ the D-ring 28 and the support radius 74 is remains horizontal.
The panel 20 of the device is therefore subject to a direct horizontal force pulling the panel into contact with the back of the wearer. This is despite the fact that the hinge 33 of the device enables the strap 26 to angle dowllw~dly from the back of the wearer to the D-ring 28. The hinge permits the device to ride below the widest part of the abdomen of the wearer having this body type. This is the most comfortableposition for the wearer.
The tlim~n~ions of the panel 22 and the location of the hinge 33 ensure that there is sup~ort for the abdomen of the wearer while pft",iLI;ng ease of movement by riding above the iliac crest and below the ribs. The panel 20 provides heat retention and support for the lower lumbar and upper sacrum regions of the wearer's back.
In Figure 6a, the back support device of the plcfcllcd embodiment is shown in position on a female wearer having an average body type with a heightlweight ratio of 2.5 pounds per inch or less. Figure 6b shows the support device of Figure 6a in schem~tic lcpre~n~ ;on i1111~t~ting the relative positions of panel 20 and panels 22.
As is shown in Figure 6a, and more particularly in Figure 6b, in this case, the strap 26 remains much as is the case with the device as shown in Figure 4. Again the belt rides above the iliac crest and below the ribs. There is a h- ri7nnt~1 im~gin~ry line belwæn the D-ring 38 and the support radius 74.
In Figure 7a, the back support device of the plcr~l~d embodiment is shown in position on a female wearer having a full figure body type with a height/weight ratio more than 2.5 pounds per inch. Figure 7b shows the support device of Figure 7a in sch~ c lG~ n~ n i11l.~h~l;ng the relative po~itionc of panel 20 and panels22. As is shown in Figure 7a, and more particularly in Figure 7b, in this case, an im~in~ry line belwæ,~ the D-ring 28 and the support radius 74 is remains horizontal.
The panel 20 of the device is th~crolc subject to a direct hori7Ont~1 force pulling the panel into contact with the back of the wearer. This is despite the fact that the hinge 33 of the device enables the strap 26 to angle upwardly from the back of the wearer to the D-ring 28. As is the case with the body types illustrated in Figures 4, 5, 6, the hinge 33 in Figure 7a permits the device to ride above the widest part of the hip of the wearer having this body type. This is the most co"lfol~ble position for the wearer.
The ~iim~onsion~ of the panel 22 and the location of the hinge 33 ensure that there is support for the abdomen of the wearer while pe~n~ ;ng ease of movement by riding above the iliac crest and below the ribs. The panel 20 provides heat retention and support for the lower lumbar and upper sacrum regions of the wearer's back.
In use, the back support device of the invention is worn about the waist area as shown in Figures 4-7b. The back support panel 20 is placcd over the lower lumbar and upper sacrum of the wearer's back. The abdominal panels 22, 24 are then brought around the side of the wearer and the strap introduced into D-ring 28 and pulled tight. If n~es~.y, ends 46, 48 can be adjusted in D-rings 35, 36. Thewearer will adjust the device so that it rides co---follably on his or her body. As is shown in Figures 3-7b, the positioning of the belt will vary depen-ling on the girth of the wearer.
S By sizing the abdominal panels 22, 24 a~pr~lialely, and by providing hinges 33, 34, the r~ .g of the device to encircle the girth of the wearer brings the back support portion of the device into firm contact with the lumbar and upper sacrumregion of the back. The non-elastic nature of the back support device provides support for the lumbar and upper sacrum region of the back while the siæ and shape of the panels 20, 22, 24 and the arrangement of hinges 33, 34 ensure that a snug fit may be ob~i ed for Weale,l~ having dirrertnt body types despite the non-elastic nature of the device. The ...~ n~nc~ of a snug fit assists in both support for the back and the abdominal m~ s, and for the re~ntion of heat, both of which assist in the pl~ ion of injuries to the back and the abdominal m~lsrles.
Adjllstmen~ of the belt is possible such that the pr~s~ule against the back region may be indep~n-l~ntly adjusted in co---p~ on with the pl~;SSUle, against the abdomen. Straps 46, 48 may be pulled tighter or loosened through D-rings 35, 36 in order to apply more or less pr~s~u,e to the back by way of panel 20.
;v~ly~ strap 26 may be tig~ n~d or loosen~d through D-ring 28 to put more or less pless.lle on the abdomen (the stomach region) by way of abdominal panels 22, 24.
Other v~riqtion~ and mo~ifir~tions of the invention are possible. All such mo~ifir~tion~ or v~ri~ti~n~ are believed to be within the sphere and scope of the invention as defined by the claims appended hereto.
