As disclosed, the vest of the present invention comprises an upper torso member, a lower belt member, and a plurality of vertical support members fixedly attached at each end to the upper and lower members, wherein each of the vertical support members contains therein an inflatable bladder in fluid connection to an inflation means. ## Claims ### Claim 1 An inflatable lumbar traction device, comprising: an upper torso member; a lower belt member for affixing about a wearer's hips; and a plurality of support members, each fixedly attached at a first end to the upper torso member and at a second end to the lower belt member; wherein the plurality of support members are distributed both posteriorly and anteriorly to the upper torso member and the lower belt member; further wherein each of the plurality of support members contains therein at least one inflatable bladder; further wherein the at least one inflatable bladder of each of the plurality of support members is in fluid communication with an inflation device; further wherein each support member is spaced from an adjacent support member by a predetermined distance to provide overall flexibility to the device. ### Claim 2 (depends on 1) The inflatable lumbar traction device of claim 1, wherein the plurality of support members comprises five support members. ### Claim 3 (depends on 1) The inflatable lumbar traction device of claim 1, wherein the plurality of support members comprises four support members. ### Claim 4 (depends on 1) The inflatable lumbar traction device of claim 1, wherein the inflation device comprises a manual pump. ### Claim 5 (depends on 1) The inflatable lumbar traction device of claim 1, wherein the inflation device comprises a compressed-fluid system. ### Claim 6 (depends on 1) The inflatable lumbar traction device of claim 1, wherein each support member is free of contact with any adjacent support member. ### Claim 7 (depends on 1) The inflatable lumbar traction device of claim 1, wherein the plurality of support members comprises a plurality of substantially vertical support members. ### Claim 8 (depends on 1) The inflatable lumbar traction device of claim 1, wherein each of the support members is disposed substantially transversely to both the upper torso member and the lower belt member. ### Claim 9 An inflatable lumbar traction device having an anterior portion and a posterior portion and being designed to be worn on the body of a wearer, the body having a torso extending generally from the wearer's hips and rib cage to the wearer's arms, the inflatable lumbar traction device being in fluid communication with an inflation device, the inflatable lumbar traction device comprising: an upper torso member for being disposed proximate the wearer's rib cage; a lower belt member for being disposed proximate the wearer's hips; a plurality of inflatable support members collectively being distributed on the posterior portion and on the anterior portion of the inflatable lumbar traction device, each of the plurality of inflatable support members having a first portion operably coupled to the upper torso member and a second portion operably coupled to the lower belt member; and a plurality of fluid access ports respectively operably coupled to the plurality of support members, the plurality of fluid access ports being in fluid communication with the inflation device; wherein each support member is spaced from an adjacent support member by a predetermined distance to provide overall flexibility to the device. ### Claim 10 (depends on 9) The inflatable lumbar traction device of claim 9, wherein the upper torso member includes arm access contours for accommodating generally unrestricted movement of the wearer's arms. ### Claim 11 (depends on 9) The inflatable lumbar traction device of claim 9, wherein the upper torso member is formed of a flexible fabric material. ### Claim 12 (depends on 9) The inflatable lumbar traction device of claim 9, wherein the lower belt member is front-fastening and comprises a fastener disposed anteriorly to the lower belt member. ### Claim 13 (depends on 9) The inflatable lumbar traction device of claim 9, wherein the plurality of inflatable support members comprises at least four inflatable support members, at least two of said inflatable support members being disposed anteriorly of the upper torso member and lower belt member and at least two of said inflatable support members being disposed posteriorly of the upper torso member and lower belt member. ### Claim 14 (depends on 9) The inflatable lumbar traction device of claim 9, wherein the plurality of inflatable support members comprises five inflatable support members, two of said inflatable support members being disposed anteriorly of the upper torso member and the lower belt member and three of said inflatable support members being disposed posteriorly of the upper torso member and the lower belt member. ### Claim 15 (depends on 9) The inflatable lumbar traction device of claim 9, wherein each of the inflatable support members comprises at least one bladder. ### Claim 16 (depends on 15) The inflatable lumber traction device of claim 15, wherein each bladder is formed of an elastic material. ### Claim 17 (depends on 15) The inflatable lumber traction device of claim 15, wherein each bladder comprises a stiffening support formed integral therewith for increasing the stiffness of the corresponding inflatable support member. ### Claim 18 (depends on 15) The inflatable lumbar traction device of claim 15, wherein each bladder is operably, fluidly coupled to the inflation device and is inflatable thereby to a maximum of twenty pounds per square inch. ### Claim 19 (depends on 15) The inflatable lumbar traction device of claim 15, wherein each bladder is operably, fluidly coupled to the inflation device and is inflatable thereby to a maximum of between six and twelve pounds per square inch. ### Claim 20 (depends on 9) The inflatable lumbar traction device of claim 9, wherein each of the inflatable support members is disposed substantially transversely to both the upper torso member and the lower belt member. ### Claim 21 (depends on 9) The inflatable lumbar traction device of claim 9 wherein each of the inflatable support members includes outer sleeve material, said outer sleeve material acting to limit radial expansion of the inflatable support member when the inflatable support member is inflated. ### Claim 22 (depends on 21) The inflatable lumbar traction device of claim 21, wherein the outer sleeve material is formed of fabric. ### Claim 23 (depends on 22) The inflatable lumbar traction device of claim 22, wherein the fabric of the outer sleeve material is selected from a group consisting of canvas and nylon. ### Claim 24 (depends on 9) The inflatable lumbar traction device of claim 9, wherein each inflatable support member comprises a check valve for substantially preventing overinflation. ### Claim 25 (depends on 9) The inflatable lumbar traction device of claim 9, wherein the plurality of inflatable support members comprises a plurality of substantially vertical inflatable support members. ### Claim 26 (depends on 9) The inflatable lumbar traction device of claim 9, wherein each support member is free of contact with any adjacent support member.
