  • the present device is a lumbar support device comprising a frame assembly, which includes frame members and a web, configured for being disassembled by a user, and later reassembled by the user to form a frame of the lumbar support for use in supporting a lumbar area.
  • various embodiments of the lumbar support frame assembly are configured for maintaining the frame assembly in an assembled state, while the lumbar support props a user's lower back and therefore bears a considerable share of the weight of the subject's back.
  • the lumbar support frame assembly are configured for maintaining the frame assembly in an assembled state, while the lumbar support props a user's lower back and therefore bears a considerable share of the weight of the subject's back.
  • embodiments illustrate frame assemblies capable of convenient assembly. Once the frame assembly is in the assembled state, the web can be tensioned over the frame when the lumbar support is in an operative configuration so that, when the lumbar region of a user applies pressure on the web, the web, in reaction to the pressure, provides support to the lumbar region.
  • the support that the web provides in tension is created by the frame of the lumbar support, which, partly due to its curved shape and contoured form, forces the web forward in the desired lumbar region of the user so that the web is beneficially contoured to provide ergonomic support to the lumbar region of the user.
  • the frame when not in use, can be disassembled so that the device can be stored and carried conveniently, e.g., in carry-on luggage.
  • the web can serve as a bag for storing the frame members.

  • the web 106 provides a supporting surface that forms a resilient yet yieldable surface that deforms when pressed on, so that the lumbar support 102 conforms to a substantial extent to the shape of the portion of the user's back that it is designed to support, which includes the lumbar region.
  • the web 106 can be composed of any flexible, foldable material that provides the physical characteristics to serve the function described herein. In one embodiment of the claimed device, the web exhibits limited stretch, so that it can be tensioned over the frame.
  • the lumbar support 102 therefore provides substantial resistance to the lumbar region of the user in order to provide the desired beneficial support.
  • An example embodiment of the web 106 is a single expanse of material comprising any one or a blend of materials including without limitation: cotton, flax, hemp, wool, polyester, acrylic, nylon, rayon, acetate, spandex, elastane (Lycra®), aramid (Kevlar®), leather, leatherette, plastic, vinyl, polyester suede, a heavy woven fabric, or any other similar or related material having sufficient strength and durability to support the back of the user of the device, while preferably providing a limited amount of stretch or "give.”

As shown, the left and right sides, 114 and 112 respectively, of the lumbar support have symmetrical curvatures. In the example embodiment shown in FIG. 3, the shape of the collapsible frame assembly 120 becomes wider towards the bottom of the lumbar support 110 as compared to the shape of the frame assembly 120 towards the top of the lumbar support 108.
  • FIG. 4 shows a front view of an embodiment of a collapsible frame assembly 120.

  • materials include but are not limited to any of the thermoset plastics or thermoplastics such as polyethylene (PE), polypropylene (PP), polyvinyl chloride
  • the frame members can also be made from plastic or rubber coated metal.
  • the frame members are constructed of a bendable metal alloy tubing, the alloy being suitably flexible to permit bending of the segments into the desired curvilinear shape for constructing the frame, and also rigid and durable enough to maintain the structural integrity of the assembled frame in use without the need for tension straps.
  • the frame members are constructed of a grade 304 A-269 stainless steel hollow tubing that is 0.500 inches in diameter and 0.049 inches thick.

Lateral, vertical, or any other movement or rotation except the desired disconnection or folding of the joints is prevented by the use of sleeves, support straps
  • connectors can include sleeveless joints that are able to restrict movement of the frame members while the lumbar support is in use.
  • the mechanism used for the plurality of joints 195 for providing relative movement of the frame/body members about a pivot axis is established by a locking position and a rotatable release position of the joints, such that, in the locking position, the two frame/body members are assembled with one another by means of a toothed portion that locks the two frame/body members into place, and in the release position, the second frame/body member is moveable with respect to the first body member.
  • the assembling and disassembling ends of the plurality of joints can be established by a cotter and sleeve joint with one joint end forming a housing sleeve to receive the other joint end.
  • each of the ends has at least one hole in alignment with a hole in the other joint member such that, when the joint members are assembled together, a cotter in the form of a bolt, wedge, key, or pin enters the holes to lock the joint members together.
  • Another example joint mechanism is established by an axle and a pin arranged to extend into and slide back and forth in the pin-receiver slot in the frame member hinge joint.
  • Yet another example joint mechanism is established by a knuckle joint with a locking mechanism for providing relative movement of a first and second body member about a pivot axis, wherein the first and second body members alternate between a locking position and a rotatable release position, such that, in the locking position, the two body members are assembled with one another by means of a toothed portion that locks the two members into place, and in the release position, the second body member is moveable with respect to the first body member.
  • Another example joint mechanism is established by a universal joint comprising two ends of two frame members that are pivotally connected to each other.
  • members are joined by key and keyhole connections, each comprising a keyhole slot through the ends of both members to be joined, and a key to be inserted through the slot in order to fix the members in a joined position.
  • Each keyhole can be shaped in such a way to match the key, and such that the key cannot be pulled directly out of the keyhole when the key is moved into a locking portion of the keyhole. In order to remove the key from the keyhole and thus disengage the two frame members, the key needs to be slid upward to the upper part of the keyhole.
  • An example shape of such a key and keyhole pair can be in the shape of a T.
  • members are joined by a screw or bolt and receiver connection. There are one or more holes through each end of a member (at two or more of the locations A, B, C, D, E, and F) which contains portions of a receiver such that, when the two members are slid together and aligned, a complete receiver is formed. The screw or bolt is then twisted through each receiver formed by the set of aligned holes at the ends of the members.
  • the frame assembly alternatively includes four members: an upper portion 208 comprised of a substantially flattened, curvilinear, U-shaped upper frame member DE, a base portion 210 comprised of a substantially flattened, curvilinear, U-shaped lower frame member CB, a right side portion 212 comprised of a curvilinear frame member BE, and a left side portion 214 comprised of a curvilinear frame member CD.
