in the preferred embodiment of the invented sling apparatus , an eyelet or connectors positioned above the shoulder provides the point of attachment for the suspension system to the rigid support frame . preferably , the eyelet is fixedly secured to the free end of the elongated support arm . the suspension system comprises one or more lifting / suspending devices adapted to lift the arm in cooperation with the support frame . in the preferred embodiment , adjustable suspension straps ( elastic or inelastic ) are removably attached at one end to the eyelet and fixedly secured at the other end to a plurality of cuffs adapted to encircle the arm . preferably , three suspension straps are attached between the eyelet and the three cuffs ( preferably , one strap per cuff ) encircling the bicep , the forearm ( adjacent the elbow ) and the wrist . the suspension straps may then be tightened or loosened so that the weight of the arm is comfortably transferred to the hips and back via the support frame . alternatively , a sleeve - like sling or other apparatus ( rigid or flexible ) may be hung from the rigid support to accept the injured arm . transferring the weight of the arm ( load ) from the shoulder to the hips and back via support frame and suspension system minimizes and preferably eliminates stress and discomfort in the neck and shoulder regions and allows the arm and shoulder to rest and / or heal . the sling apparatus may include means for further restricting or eliminating lateral and / or vertical movement of the arm . for example , the cuffs encircling the suspended arm may be anchored to the belt using straps , bands , wraps , or other fasteners to facilitate total , or near total , immobilization . these straps , bands or wraps may be tightened or loosened as necessary to facilitate varying degrees of activity or immobilization . referring now to the figures , several , but not the only , embodiments of the invented arm sling apparatus are illustrated . the arm sling of the present invention is designed to reliably support an arm without unnecessarily stressing or fatiguing the neck and / or shoulder regions . rather , the invented sling relieves the shoulder of its lifting duties by transferring the load to the hips and back via a cooperating rigid support frame and suspension system . in the preferred embodiment , the load - bearing system is substantially isolated and preferably completely isolated from the neck and shoulder regions . as a result , the arm may be effectively immobilized , partially or completely , and the shoulder allowed to rest and / or heal . as shown in fig1 , the invented arm sling apparatus 10 comprises a support frame 20 and a suspension assembly 30 adapted to lift the weight of the arm and hold the arm in a generally fixed position relative to the body of the wearer . preferably , the support frame 20 of the invented apparatus comprises a waist belt 22 and an upright support arm (“ upright support 24 ”) through which the forces acting on the suspension system may be conveyed to the hips or lower back . in the preferred embodiment , load - bearing components of the arm sling apparatus 10 are substantially isolated from the shoulder and neck regions . the waist belt 22 of the preferred support frame comprises a band of material that fully encircles the body of the user above the hips , as illustrated in fig1 . in other embodiments , the belt may be positioned elsewhere on the torso so long as the weight of the arm ( applied to the support frame ) is not supported by or at least substantially not supported by the neck or shoulder regions . preferably , the band is padded according to conventional methods using foams , layered fabrics or other materials for comfort . the opposing ends of the waist belt may overlap to facilitate adjustment of the belt for various body sizes and / or shapes . preferably , the belt is secured about the waist using a hook and loop closure system 26 . in the preferred embodiment , the securement means comprises all or a substantial portion of the belt surface being loop material ( or any material that receives and secures to the hook material ) and at least one tab 28 of hook material secured to the belt at the outermost end . preferably , a second tab 27 is provided on the opposite side from tab 28 , so that the hook tabs on both ends of the belt may attach to the loop material substantially anywhere along the length of the belt . this way , the belt is wrapped around the user and secured , but it is easily adjustable to many different degrees of tightness due to the hook portions 27 , 28 being capable of hooking to the belt all or substantially all along the length of the belt . further , the belt is designed so that a long end 122 curls around the user across his / her entire front , extending toward the side opposite the injured arm ( as shown in fig3 b ) to help the user more easily fasten the belt . in the example of the belt adapted for an injured right arm ( in fig2 b ), the user may typically hold the long end across his / her waist 122 with his injured right arm / hand , while he / she uses the good arm / hand to pull the shorter end 123 under the long end . then , the good arm attaches tab 28 to the underside of the long end 122 near the user &# 39 ; s right side , and then presses the long end 122 against the user &# 39 ; s left side to secure tab 27 against the belt outer surface . depending on the waist size of the user , the belt may be wrapped around the waist and the hooking ends secured in various positions along the length of the belt , as necessary , to loosen or tighten the belt . the belt is preferably at least 3 inches wide from edge to edge and is preferably reinforced , to prevent belt roll . in the preferred embodiment , upright support arm 24 is secured to the waist belt 22 at or near its central region ( but typically sightly to the left or right for a left or right injured arm , respectively ) via a rigid or semi - rigid connector 29 , as shown in fig2 b . as shown in fig2 c - e , the connector 29 comprises generally a long , thin waist plate 31 , which conforms substantially to the circumferential contours of the back , and an upending plate 129 generally perpendicular to plate 31 . plate 129 and support arm lower end plate 129 ′ may be curved in one or more directions to fit the back . preferably , the plate 31 is attached to the belt by a firm hook and loop connection ( using hook and loop that substantially covers the entire plate 31 and plate area 33 ), but may be attached by other means , such as sewing , adhesive , fasteners , latches , tape , etc ., or may be integral with the belt . the support arm is preferably attached to the connector 29 preferably by means of a firm hook and loop connection , wherein the hook and loop materials ( hook and loop securement means 32 , 32 ′) preferably cover all or substantially all of the connector upending plate 129 and of the lower end plate 129 ′ of the arm , but may be attached by other means such as sewing , adhesive , fasteners , latches , tape , welding , etc ., or may be integral with the connector and / or belt . preferably , tightening the waist belt pulls the connector into firm contact with the back of the wearer to substantially immobilize the connector 29 . this way , lateral movement of the upright support arm is sufficiently eliminated so long as a rigid connection between these two components ( plate 129 and arm lower end plate 129 ′) exists . the connection between the circumferential waist plate 31 , a plate area 33 of the waist belt , and the lower end plate 129 may be further reinforced and secured by cover 34 ( fig2 f ). cover 34 wraps around the combination of belt area 33 , plate 31 , and lower end plate 129 ′ and is secured to itself and / or to the belt preferably by hook and loop connections , affording a more secure anchoring of the support arm and also affording padding between the waist plate 31 — lower end plate 129 ′ combination and the user . further , additional padding may be used on various portions of the support system , for example , a gel pack 37 may be inserted into or held on the plate 129 region , for example , by means of a wrap / cover 37 ′, for cushioning the force of the plate 129 and / or the arm lower end plate 129 ′ against the back . also , cover 39 may be wrapped or otherwise attached to the curved portion 43 of the arm 24 , for aesthetic reasons . while the arm may extend integrally from the belt and / or connector , it is preferred , as described above , that the arm 24 is adjustably attached to the connector 29 , for raising and lowering the support arm relative to the belt , and removably attached to the connector or belt , for disassembling the apparatus for transport and storage . while a hook and loop attachment is preferred , clamps , bolts , locking pins , or other fasteners may also be used , and points at which the connector and / or support arm contact the back of the wearer may be padded with foams or gel pads and then wrapped with soft fabrics , or other materials , to increase comfort . in the case of detachably secured components , the padding structures are preferably removable to facilitate disassembly . to strengthen the connection and / or increase stability of the upright support , additional structure may be implemented . for example , a diagonal stabilizing strap 34 may be attached between the waist belt and a point , generally the midpoint 36 , on the upright support member to further inhibit side - to - side motion of the support 36 , as shown in fig3 a . in the preferred embodiment , the upright support 24 comprises a lightweight , durable and inflexible arm extending up from the waist belt in a generally vertical orientation , as is also shown in fig3 a . the arm may be constructed of a lightweight metal , such as aluminum , or a hard plastic . other alternatives may also be foreseeable to one skilled in the art . in use , the upright support arm 24 preferably extends from the rigid connector 29 generally at or near the waist ( preferably in the central region of a wearer &# 39 ; s back but optionally toward the right or left side but behind the right or left arm , respectively ) over the shoulder to a position generally forward of the chin and above the shoulder corresponding to the arm being suspended , as shown in fig3 a - d . preferably , the support arm is slightly curved so that it roughly follows the contours of the body as it extends from the back of the wearer to the front . however , it is important that the curved support provide sufficient clearance for , or separation from , the neck and shoulder regions so that these areas are not stressed or fatigued when the weight of the arm is applied to the arm sling apparatus . preferably , the length of the upright support arm 24 is adjustable to accommodate individuals of various heights , and this adjustment may be accomplished by the adjustable connection between the arm and the connector ( lower end 129 ′ and the upper plate 129 ). the arm 24 may be raised and lowered several inches on the connector plate 129 while still being securely held on the connector , so that a single sling apparatus 10 may fit many different individuals . alternatively , the support arm 24 may be produced in several different sizes ( s , m , l , xl ). the distal end 42 of the arm 24 should extend forward enough so that any suspension straps 36 do not rest on or rub against the user , but instead extend through space to the cuffs / sling holding the user &# 39 ; s arm . the arm 24 preferably curves in a “ shepherds hook ” style up along the back and then approximately 180 ° at its top . the preferred arm 24 extends up along the user &# 39 ; s back ( typically in the range of about 14 - 25 inches for an adult , for example ) and curves in a radius in the range of about 6 - 15 inches , and most preferably about 10 - 12 inches to stay distanced from the shoulder blade region , the top of the shoulder , the neck , and the front of the shoulder . above the shoulder , an eyelet 42 is preferably attached to the “ free ” end of the support 24 , as shown in fig2 b - e and 3 c - d . in the preferred embodiment , the eyelet 42 is fixedly and immovably secured to the support arm 24 such that total immobilization of the suspended arm may be achieved . however , in other embodiments , the eyelet may hang loosely or swivel to accommodate greater range of motion . preferably , the length of the support arm is selected , or adjusted , so that the upper most extremity 124 of the arm is at least 1 ″ above the shoulder , as shown in fig3 a - d . preferably , there is at least 1 inch , and most preferably at least 2 inches , of separation between all surfaces of the support member and the neck and shoulder so that pressure is not applied to these areas . in the preferred embodiment , the eyelet 42 comprises the junction between the support frame assembly 20 and the suspension system 30 of the invented arm sling apparatus 10 . the suspension system 30 of the arm sling apparatus 10 comprises means adapted to encircle and / or contain the arm such that the weight of the arm may be transferred from the shoulder to the support frame . in the preferred embodiment , a plurality of suspension straps 36 are removably attached to the eyelet 24 above the shoulder , as shown in fig3 a - d . the proximal ends 47 of these suspension straps 36 may be attached to the eyelet 24 using any of a number of conventional , releaseable hooks 44 or clasps . preferably , the suspending straps 36 comprise conventional , webbed straps 45 that may be flexed , but not stretched . however , some elasticity may be provided in the straps of various embodiments for comfort / shock - absorption or to permit increased range of motion . for example , a short length of elastic may be used as the proximal end 47 of the suspension straps 36 , as this tends to reduce shock to the sling member and consequently to the user &# 39 ; s arm , without making the straps 36 so elastic that their role as suspending and supporting devices is compromised . the straps 36 are preferably generally flat , but may also be round or other shapes , and may include cords , tethers , cables , or other elongated members . the straps of the preferred embodiment may be lengthened or shortened via any of a number of conventional adjustment mechanisms 46 , an example of which is demonstrated in fig4 a . preferably , the distal ends 48 of the suspension straps are secured ( one each ) by a buckle or other fastener 49 to a plurality of cuffs 50 adapted to encircle the arm , as shown in fig4 b . in operation , the suspension straps 36 and cuffs 50 form a suspension system ( see fig1 ) wherein the weight of the arm may be transferred to the hips and back via the support frame 20 . this cooperation between suspension system 30 and support frame 20 allows the arm sling apparatus to lift the arm into a particular position relative to the body to unload the shoulder and neck . the cuffs 50 of the arm support system comprise a band 52 of material adapted to wrap around the circumference of the arm at various points , as shown in fig4 b . in the preferred embodiment , three cuffs are positioned on the arm in generally the following areas : the bicep , the forearm ( adjacent the elbow ) and the wrist , as shown in fig1 and 3 . the cuffs are preferably padded using layered fabrics , foam or other cushioning methods for increased wearing comfort . at opposite ends of the cuffs , tabs of hook and loop material 28 , 27 ′ are fixedly secured to the opposing surfaces , as is also shown in fig4 b . the tabs are arranged such that when the cuff is wrapped about the arm , the hook material 28 ′ engages the loop material 27 ′ to secure the cuff . alternatively , the cuffs may be secured about the arm using alligator clips , clasps or other fastening means . other embodiments of the suspension system may include a single , wider wrap or sleeve 50 that extends around substantially all of the forearm on three sides , and attaches to the eyelet as shown in fig5 a . other sling members may be designed , encircling or otherwise engaging various portions of the arm , for example , straps , cuffs , sleeves , platforms , shirt sleeve attachments , connectors to wrapping tape on the arm , connectors to arm casts , etc . in addition , some embodiments of the arm sling apparatus 10 may include a pillow 50 positioned between the arm and torso for additional comfort , as shown in fig5 b . opposite ( below ) the suspension strap attachment , a second strap , a restraining or immobilization strap 60 , is preferably fixedly secured to the cuff , as shown in fig4 c fastener 49 ′. the immobilization strap extends between the cuff and waist belt to anchor the cuff and , therefore , the arm relative to the body , as shown in fig1 and 3 . in some embodiments , a plurality of immobilization straps may be fixedly attached to each of the cuffs to permit further immobilization ( not shown ). in the preferred embodiment , the immobilization straps ( one for each cuff ) are removably secured to the waist belt via belt - encircling straps 62 and 60 alligator clips 64 or other detachable hooks or clasps , as shown in fig3 b - d . as with the suspension straps , the lengths of the immobilization straps are preferably adjustable using conventional techniques and equipment , such as adjustor 66 . this way , the extent of immobilization may be selected or adjusted as necessary . in addition belt - encircling straps 62 may be slid longitudinally on the belt to adjust the direct and location of the force applied by the immobilization straps . in combination , the restraining / immobilizing straps restrict the amount of downward and outward ( away from the body ) motion of the arm , respectively . in addition , the immobilization straps may be tightened so that upward motion of the arm and / or lateral movement across the body is restricted or prevented . typically , the invented arm sling apparatus will find application to situations in which an arm or shoulder has been injured and requires rest . for example , the apparatus may be worn after shoulder surgery is performed to immobilize the arm and allow the shoulder to heal properly , as shown in fig1 . in addition , the sling may be helpful for rehabilitation purposes wherein increasing amounts of movement and / or load - bearing may be permitted to strengthen the arm and / or shoulder . the arm sling may also be worn following the breaking of an arm . in such situations , whether a cast is worn or not , at least minimal immobilization of the arm is often required . the invented arm sling apparatus facilitates restriction of arm motion without placing stress on the shoulder or neck regions as is common with many existing slings . in addition to these limited examples , other useful applications of the invented apparatus may be foreseeable to one skilled in the art . for example , the apparatus may be worn to support the arm during various activities requiring repetitive or prolonged stresses to the arm and / or shoulder musculature , particularly those in which the arm may be in an outstretched or weak position , as shown in fig6 a - d . examples of such activities are painting , sculpting and other arts , welding , gardening , etc . fig6 d illustrates a sling apparatus according to one embodiment of the invention being used by a welder , wherein the welding hose 201 is supported by the support 24 arm and attached to the support arm 24 by a wrap / fastener 202 . this illustrates how the weight of an object or tool may be minimized by being attached to and / or supported by the support arm , and how the object or tool in this way is also properly kept in place during use to guard against stress and injury to the user . while the term “ strap ” is used herein for suspension straps and immobilization straps , it is to be understood that these components are not necessarily limited to being flat and not necessarily limited to being made of cloth or webbing . the term “ strap member ” in the claims may also include various fastening devices , such as elongated and / or adjustable clips , tethers , brackets , cords , strings , loops , etc . that will serve in the capacity of the suspension straps and immobilization straps extending between the arm and the sling member , and extending between the sling member and the belt , respectively . further , the sling member and the suspension strap ( s ) may be combined into a single unit that hangs from the support arm and encircles and / or supports the arm . also , when there are a plurality of strap members being used , they need not all be identical . while the preferred embodiments include a single support arm , embodiments may also include more than one support arm , either on both sides of the person or even on a single side . further , there may be additional items hung from or supported by the support arm , belt , and / or sling member . although this invention has been described with reference to particular means , materials and embodiments , it is to be understood that the invention is not limited to these disclosed particulars , but extends instead to all equivalents within the scope of the following claims .
