Preferably, the tension member extends in a height direction along the back surface of the user. Preferably, the belt has a cushion at least in a portion that contacts the back surface of the user.

  According to the present invention, it is possible to provide a simple and inexpensive low back pain prevention / reduction device that can be easily used in daily life.

  Hereinafter, a preferred embodiment of the present invention will be described with reference to the accompanying drawings.

  FIG. 1 shows a back pain prevention / reduction device of this embodiment. As shown in the figure, the low back pain prevention and mitigation device 1 is mainly composed of a belt 2 wound around the abdomen H of the user U and a tension member 3 to which the belt 2 is attached and whose lower end 3a is seated on the seat surface Z of the chair C. It is configured.

  As shown in FIGS. 2 and 3, the belt 2 of the present embodiment is made of an elastic member such as rubber and can be elastically expanded and contracted. The belt 2 can be adjusted steplessly to match the circumference of the user's abdomen. For example, both end portions 4 and 5 of the belt 2 can be detachably connected to each other at an arbitrary position. In the present embodiment, a hook-and-loop fastener 6 (for example, Velcro (registered trademark)) as a connecting member made up of a myriad of nylon and other collars and rings is provided at both end portions 4 and 5 of the belt 2. The hook surface portion 7 having an infinite number of hooks in the hook-and-loop fastener 6 is formed on the surface of the one end portion 4, and the ring surface portion 8 having an infinite number of rings in the hook-and-loop fastener 6 is formed on the back surface of the other end portion 5. Yes. However, these may be reversed. The belt 2 is preferably wrapped around the user's abdomen as widely and stably as possible. In this way, the belt 2 can be given a corset function. Accordingly, the belt 2 of the present embodiment is relatively wide and elastically expandable. Both end portions 4 and 5 of the belt 2 are divided into a plurality (two in this embodiment) in the width direction or vertically. A cushion 9 is provided on the back surface of the belt 2 to soften the feel. Such a cushion may be provided on almost the entire back surface of the belt, or may be provided partially (particularly on a portion corresponding to the back surface of the user).

  As shown in FIG. 4, the tension member 3 can be formed of a rod or the like, but is preferably formed of a plate-like member as in the present embodiment. For example, a wooden board, a resin or plastic board, a metal board, etc. can be used. In the present embodiment, a simple flat plate is used, but a curved surface may be appropriately formed according to the shape of the back surface of the person or the backrest surface of the chair. The lower end 3a of the tension member 3 has a flat cross section in the present embodiment. However, in order to stabilize the seating on the seat surface of the chair, a horizontal protrusion 13 as indicated by a virtual line may be provided.

  The belt 2 can be detachably fixed to the tension member 3 at an arbitrary height position of the tension member 3. The fixing member in the fixing portion is also composed of the same surface fastener 10 as described above, and in this embodiment, the collar surface portion 12 is the surface of the portion 2a (the central portion of the belt 2) of the belt 2 positioned on the back surface H of the user U. The ring surface portion 11 is formed over a predetermined height range above the lower end 3 a of the tension member 3. With this configuration, the belt 2 is detachably fixed to the tension member 3 so that the height position can be adjusted. Note that the flange surface portion 12 may be formed on the tension member 3 and the ring surface portion 11 may be formed on the belt 2.

  In this way, the surface of the portion 2 a of the belt 2 positioned on the back surface H of the user U is fixed to the surface of the tension member 3. Further, the tension member 3 in the fixed state extends in the height direction along the back surface H of the user U.

  Now, in use, as shown in FIG. 1, the belt 2 is wound so as to be closely attached to the abdomen H of the user U, and both ends 4 and 5 are fixed. Then, while the lower end 3 a of the tension member 3 is seated on the seat surface Z of the chair C, the tension member 3 is leaned against the backrest S of the chair C with the surface with the ring surface portion 11 facing or facing forward. Thereafter, the user U once sits on the seat surface Z of the chair C, then floats slightly, leans back, and presses the flange surface portion 12 of the belt 2 against the ring surface portion 11 of the tension member 3. As a result, the belt 2 and the tension member 3 are fixed, and when the user U tries to sit on the seat surface Z of the chair C again in this state, the tension member 3 stretches and lifts the abdomen of the user U via the belt 2. Become. The butt A of the user U cannot be completely seated on the seat surface Z of the chair C (that is, the user cannot sit completely). The butt A of the user U is in a slightly raised state as compared to when sitting completely, and is weakly in close contact with the seating surface Z or is not in extreme contact. Even in this case, since the thighs are usually attached to the seating surface Z and both feet of the user U are on the floor, the stability of the user is maintained. The tension member 3 is sandwiched between the user U and the backrest S of the chair C and is stable.

  At this time, the distance in the height direction from the lower end 3a of the tension member 3 to the fixing position of the belt 2 (the center of the height of the flange surface 12 of the belt 2) lifts (or biases) the abdomen H of the user U upward. ). The belt 2 slightly bites under the ribs of the user U's abdomen H, and is caught by the ribs to lift the user U's abdomen H.

  In such a use state, the user U is supported by the abdomen H and does not sit completely on the chair C, so that the waist K is pulled by the weight of the lower buttocks A. In this way, the user K is sitting and the waist K is pulled. The posture also improves. In addition, since the user U is supported by the abdomen H, the burden or weight on the waist K is reduced, and the lowering of the waist K is suppressed. In this way, the user U can prevent, reduce, and treat back pain by simply sitting on the chair. Even if the user's U butt A is seated on the seat surface Z, the seating is weak, and at least a part of the weight of the butt A can be used for towing the waist K, which is effective. For example, when taking a car, working in the office, drinking alcohol, watching TV at home, etc. is there. This effect was also confirmed from a prototype test by the inventor.

  In addition, as described above, the apparatus configuration is extremely simple, and is inexpensive and does not require a place. It is small and lightweight, so it can be carried and can be easily handled by women and the elderly.

  In the above-described configuration, the belt 2 is preferably stretchable to such an extent that a tight feeling is relieved, and can be stretched to such an extent that it can follow the shape of the abdomen H under the rib bone (such as a constricted shape or a protruding shape). However, it is preferable that it can be expanded and contracted to such an extent that it does not extend too much when the weight is supported. However, the belt 2 may not be stretchable.

  Patent Document 2 discloses a device that stretches the waist and back by fixing the vicinity of the lower part of the patient's ribs and lowering the seating surface. However, the present invention lifts the abdomen by stretching the seating surface of the chair. Thus, unlike the device described in Patent Document 2 which supports the vicinity of the lower rib of the patient independently from the chair on the device main body side, it is not easily conceivable.

  Various other embodiments of the present invention are possible. For example, it is convenient to provide means for readjusting the circumferential length of the belt by further tightening or loosening after the belt is wound. It is also possible to provide a pocket for putting a wallet, a mobile phone or the like on the belt, or an attaching means (such as a rubber band) for attaching the tension member to the back of the chair. The back pain prevention / reduction device of the present invention can be applied to a chair without a backrest. The present invention should not be construed as being limited to the above-described embodiments, but can be variously modified within the scope of the invention defined in the claims, and is interpreted as covering equivalents. Should.

It is a side view which shows the use condition of the low back pain prevention-reduction apparatus which concerns on this invention. It is a front perspective view of a belt. It is a back perspective view of a belt. It is a front perspective view of a tension member.
