In FIGS. 1 (A), 1 (B) and 2, the waist supporter according to the present embodiment is composed of a trapezoidal double sheet body 11, and the sheet body 11 is brought into contact with the waist portion of the wearer. It is formed by laminating a waist contact portion 1 to be adhered to and a plurality of belts having different contraction forces, and one side end of each belt is attached to each of the left and right side portions of the waist contact portion 1. The left and right contraction tightening portions 2 and 3 to be fixed, and the left and right end edge portions 41, to which the other side ends of the left and right contraction tightening portions 2 and 3 are fixed, respectively. The loop fastener 42 and the hook fastener 52 formed from 51 and sewn to the left and right edge portions 41 and 51 are freely formed and attached to the waist of the wearer. It is configured to include parts 4 and 5.

Of these belts, the inner belts 21 and 31 located on the wearer side have a higher rigidity than the outer belts 22 and 32 located on the outer side of the left and right contraction tightening portions 2 and 3. Moreover, the contraction force in the left-right direction is formed to be small. Further, the inner and outer belts 21, 31, 22 and 32 are fixed at different upper and lower positions between the waist contact portion 1 and the adherend engaging portions 4 and 5 at both ends thereof and contracted. The configuration is such that the directions are different from (F ₁ and F ₂ ) and (F ₃ and F ₄ ).

The inner belt 21 (or 31) is laminated with the outer belt 22 (or 32) in a superposed state, and is configured to exert a contraction force in different directions without being affected by mutual contraction / extension movements. ..
Further, the left and right contraction tightening portions 2 and 3 are configured such that fabrics 23 and 33 formed of elastic mesh knitting or the like are further inside the inner belts 21 and 31. The fabrics 23 and 33 are made of a knitted fabric or a woven fabric having the same or higher elasticity than the inner belts 23 and 31.

The waist contact portion 1 has a configuration in which a pair of plates 12 and 12 made of elastic materials are inserted into the double sheet body 11 to abut and support the wearer along the waist S-shaped curve. Further, at the boundary between the waist contact portion 1 and the left and right contraction tightening portions 2 and 3, and inside the center of the contraction tightening portions 2 and 3, respectively, the non-slip portions 13, 14, 24 are formed in the vertical direction. , 34 are arranged.

Next, the attachment operation of the lumbar supporter according to the present embodiment based on the above configuration to the attached person and the action due to the attachment will be described with reference to FIGS. 3 and 4.
First, the waist contact portion 1 of the waist supporter according to the present embodiment is brought into contact with the waist portion of the wearer, and in this state, the wearer attaches the corresponding contact engagement portions 4 and 5 with his / her left and right hands. While grasping and stretching the front, overlap with the lower abdomen and engage and fix. In the state of contact of the lumbar contact portion 1 with the waist of the wearer, the lumbar contact portion 1 is formed in a trapezoidal shape, and the long base of the trapezoidal shape is stably supported by the pelvis of the lumbar region. Since the short side of this trapezoidal shape supports the lumbar spine of the wearer, it can follow and support the wearer's movements, especially various movements such as twisting, forward leaning, and backward leaning. Become.

Due to the engagement and fixing by the adherent engaging portions 4, 5, the fabrics 23 and 33 of the left and right contraction tightening portions 2 and 3 are in close contact with both sides of the waist and the lower abdomen of the adherend, and the fabric 23 is in close contact with each other. , together with the inner belt 21 and 31 from the top of 33 is added to shrinkage force in the direction of contracting direction _(F 3 · F _4), the outer side belt 22 and 32 contracting direction from the outside of the inner belt 21 and 31 _{(F 1} -A larger contraction force is applied in the direction of F ₂ ) over the entire circumference of the wearer's waist and lower abdomen. And the contractile force by the inner belt 21,31 _(F 3 · F ₄₎ and the contraction force by the outer belt _{22,32 (F 1 · F 2)} , each pressed from different directions, contractile force of the inner belt 21 and 31 (F ₃・ F _{4 ) The contraction force (F 3}・ F ₄ ) by the outer belts 22 and 32 having a larger contraction force pressurizes from the outside, and the intersecting part is the waist and lower abdomen of the wearer. Pressurization is performed by the superimposed contraction force, and the lumbar region and lower abdomen of the wearer can be individually and independently pressurized by different contraction forces and contraction directions at the non-intersecting portion.
By such an interaction between the inner belts 21 and 31 and the outer belts 22 and 32, it is possible to accurately and immediately support any movement mode of the wearer.

It should be noted that the fabrics 23 and 33 are the innermost cloths 23 and 33 on the inner side closest to the wearer in the state of being individually independent by the inner belts 21 and 31 and the outer belts 22 and 32 and being pressed against the wearable person superimposed on each other. It functions to alleviate or protect the rubbing and excessive pressurization of the inner belts 21 and 31 and the outer belts 22 and 32 due to differences in contraction force and the like.

The pressurization by the inner belts 21 and 31 and the outer belts 22 and 32 is divided into left and right from the back waist of the wearer to independently generate contractile forces, and these inner and outer contractile forces and Since the contraction direction is changed to act, stable support is possible in an appropriate manner in all operating states and forms of the wearer.

In particular, the inner belts 21 and 31 are made of a material having a rigid force that maintains a predetermined shape, and pressurize the wearer with a relatively small contraction force, whereas the inner belts 21 and 31 are from the outside to the outer belt. Since 22 and 32 have a small rigidity and apply pressure with a large contraction force, the waist and lower abdomen of the wearer can be supported with a large compression force while maintaining the shape of the supporter itself as much as possible.

In addition to being formed of a material having a large contractile force, the outer belts 22 and 32 are continuously arranged with lines A connecting the attachment positions of the waist contact portion 1 and the adherent engagement portions 4 and 5, respectively. it is because it is, it becomes possible to apply a large pressure by circumferential direction the line a contractile force in the tangential direction on the _{F 21 · F 11 · F 12} , F 22 · F 12 · F 22 is coincident ..

In the above embodiment, the lower side of the adherent engaging portions 4 and 5 is higher than the lower side position of the lumbar contact portion 1, and the upper side of the adherent engaging portions 4 and 5 is the upper side position of the lumbar contact portion 1. Although it is configured to be formed higher, it is also possible to configure these positional relationships to be the same height or to be reversed.

Further, in the above-described embodiment, the lumbar contact portion 1 is configured as a trapezoidal shape, but the present invention is not limited to this, and various forms can be obtained as long as the lumbar contact portion 1 of the lumbar supporter has a flat shape tapered upward. For example, as another embodiment, the lumbar contact portion may have a triangular shape or the like. When the triangular waist contact portion 1 is used, the apex of the triangle can be supported as a point on the lumbar vertebrae portion of the wearer, so that the twisting motion can be particularly followed and supported.

Further, in the above-described embodiment, the lumbar contact portion 1, the contraction tightening portions 2, 3 and the adherend engagement portions 4 and 5 are respectively bent and connected, but as another embodiment, the lumbar portion is used. The entire plane shape of the supporter may be curved (for example, banana shape, etc.), V-shaped, or linear.
