Description

[Technical field]

[0001] The present invention relates to a garment for the lower legs, and more particularly to a garment for the lower legs having a downwardly recessed portion in the upper central portion of the front and back parts of the waist top. [Background technology]

[0002] Shapewear for maintaining a beautiful figure has been proposed for some time. For example, Patent Document 1 discloses shapewear that uses a slimming fabric to correct a balanced figure. Patent Document 2 discloses shapewear that, when used as a girdle or the like, does not need to be removed when using the toilet and can maintain the shape of the wearer when worn. Patent Document 3 further discloses shapewear that adjusts the shape of the abdomen, waist, hips, and bust. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent Publication No. 2010-65371 [Patent Document 2] Patent Publication No. 2008-25070 [Patent Document 3] Japanese Patent Application Publication No. 8-209404 Summary of the Invention [Problem to be solved by the invention]

[0004] However, in recent years, it has become clear that a forward-tilted pelvis and arched back can have a detrimental effect on various parts of the body. For this reason, there has been a demand for the development of shapewear that can straighten the forward-tilted pelvis, maintain proper posture, and eliminate arched back.

[0005] The present invention has been made in consideration of the above circumstances, and aims to provide clothing for the lower limbs that makes it possible to straighten the tilted pelvis, maintain correct posture, and eliminate arching of the lower back. [Means for solving the problem]

[0006] In order to achieve the above-mentioned object, the invention of claim 1 relating to clothing for the lower limbs is clothing for the lower limbs having a waist top and a body part, characterized in that a recessed portion that is recessed downward is provided in the upper central part of the rear of the waist top.

[0007] According to the present invention, the upper part of the central part of the rear part of the waist top has a recessed part that is recessed downward, so that the central part of the front part of the waist top can be pushed upward from below, and the central part of the rear part of the waist top can be pushed downward from above. This makes it possible to correct the waist by pulling it downward and to straighten the forward-tilted pelvis, maintain a correct posture, and eliminate arched lower back.

[0008] If the upper edge of the front part of the waist top is configured to be positioned above the navel of the human body when it is worn on the human body, the side above the navel of the human body will be pulled downward and behind the waist, making it possible to straighten the tilted pelvis.

[0009] If the upper edge of the front part of the waist top portion is configured to be positioned between the third and fourth lumbar vertebrae of the human body when it is worn on the human body, the excessive lumbar forearm that has been aggravated by the forward tilt of the pelvis can be corrected so that it approaches the normal lumbar forearm, and the forward tilted pelvis can be straightened.

[0010] If the upper edge of the front part of the waist top portion is configured to be positioned between the lower part of the third lumbar vertebra and the upper part of the fourth lumbar vertebra when worn on the human body, the excessive lumbar forearm that has been strengthened by the forward tilt of the pelvis can be corrected so that it is closer to the normal lumbar forearm, and the forward tilted pelvis can be straightened.

[0011] If the lower end of the rear recess is configured to be located between the lower part of the fourth lumbar vertebra and the upper part of the sacrum when the support is worn on the human body, the excessive lumbar forearm that has been aggravated by the forward tilt of the pelvis can be corrected so that it is closer to a normal lumbar forearm.

[0012] If the lower end of the rear recess is configured to be positioned between the intervertebral disc adjacent above the fifth lumbar vertebra and the intervertebral disc adjacent below the fifth lumbar vertebra when the brace is worn on the human body, the excessive lumbar forearm that has been aggravated by the forward tilt of the pelvis can be corrected so that it is closer to a normal lumbar forearm.

[0013] When worn on the human body, when the front upper edge of the waist top portion is positioned between the third and fourth lumbar vertebrae of the human body, the lower end of the rear recess can be configured to be positioned between the lower part of the fourth lumbar vertebra and the upper part of the sacrum of the human body.

[0014] More specifically, when worn on the human body, when the front upper edge of the lumbar top portion is positioned between the lower part of the third lumbar vertebra and the upper part of the fourth lumbar vertebra of the human body, the lower end of the rear recess can be configured to be positioned between the intervertebral disc adjacent above the fifth lumbar vertebra of the human body and the intervertebral disc adjacent below the fifth lumbar vertebra of the human body.

[0015] If the depth dimension of the rear recess is set to 4 to 13 cm, the lower end of the rear recess can be positioned lower than the fifth lumbar vertebra of the human body when the device is worn on the human body.

[0016] The rear recess is formed in a V-shape, and the angle of the mutually opposing inclined lines of the V-shape is set to 15° to 45° with respect to the horizontal, so that the inclined lines can smoothly straighten the forward-tilted pelvis. By increasing the ratio of the radius of curvature of the curve connecting the tip of the spinous process of the first lumbar vertebra to the tip of the spinous process of the fifth lumbar vertebra before the seat is attached to the human body from 1.3 to 2.5, the forward-tilted pelvis can be straightened effortlessly.

[0017] The upper edge of the body portion is connected to the lower edge of the waist top portion and is formed from a stretchable fabric, and the stretch direction includes a direction that slopes downward toward the center of the back, so that it is possible to further correct the waist by pulling it downward and to the rear.

[0018] A belt-like pelvis belt portion that wraps around the pelvis on the upper side of the body portion can be provided overlapping the body portion.

[0019] The pelvic belt portion is made of a stretchable fabric, and the stretch direction of the pelvic belt portion includes a direction that slopes downward toward the center of the rear, and this direction overlaps with the stretch direction of the left body portion and the right body portion, making it possible to further correct the waist by pulling it downward and rearward.

[0020] By providing a downwardly recessed portion in the upper central portion of the front part of the waist top, it becomes possible to apply stress to the front recessed portion while pulling the waist further backward and downward at the rear part of the waist top, thereby improving the effectiveness of waist correction.

[0021] If the depth dimension of the recess in the rear part of the waist top is set to be greater than the depth dimension of the recess in the front part of the waist top, the waist can be reliably corrected.

[0022] If the depth dimension of the front recess is set to 0.1 to 1 cm, the effect of correcting the lower back can be increased.

[0023] The front recess is formed in a V-shape, and the angle of the opposing inclined lines of the V-shape is set to 0.5° to 5° with respect to the horizontal direction, thereby further increasing the effect of correcting the lower back.

[0024] The waist top section has a front waist top section at the front, a left waist top section at the left side section to the rear, and a right waist top section at the right side section to the rear, and the front waist top section is formed by overlapping at least two pieces of fabric front and rear so that they cross each other while inclining downward, forming a depression in the front section, and the upper edge side of the front and rear overlapping parts is not connected to the opposing fabric, so that the unconnected part in the front section can shift according to the body shape when worn, improving the fit. Also, the unconnected part in the front section can be prevented from being excessively tight, improving the comfort of wearing.

[0025] The left hip top is provided with a fabric that slopes downward from the left side toward the center of the rear, and the right hip top is provided with a fabric that slopes downward from the right side toward the center of the rear, and the ends of the left hip top and the right hip top are overlapped front to back so as to cross each other to form the recessed portion in the rear, and the upper edge side of the overlapped portions is not connected to the opposing fabric, so that the unconnected portion in the rear can shift according to the body shape when worn, improving the fit. Also, the unconnected portion in the rear can be prevented from being excessively tight, improving the comfort of wearing.

[0026] If the length of the non-connected portion in the front is set to 10 to 30 cm, the fit and comfort of the garment can be reliably improved.

[0027] If the non-connected portion in the front part is formed across the entire area in the left-right direction of the front waist top part, the fit and comfort can be further improved.

[0028] If the ratio of the left-right length of the unconnected portion in the front to the left-right length of the unconnected portion in the rear is 5 to 20, the fit and comfort can be further improved.

[0029] The body part is formed by overlapping multiple stretchable stretch fabrics, and includes a portion in which one stretch fabric stretches in one direction along a direction that slopes downward toward the center of the rear part, and the other stretch fabric stretches in two mutually intersecting directions, so that the stretch force of the one stretch fabric that stretches in one direction can be increased to further correct the waist area by pulling it downward, and the other stretch fabric that stretches in two directions can easily stretch according to the body shape, improving the fit. Also, the other stretch fabric that stretches in two directions can prevent excessive tightening, improving comfort.

[0030] The leg insertion opening is connected to the leg insertion part, and the leg insertion part extends downward from the leg insertion opening, and is made of a stretchable fabric with a vertical dimension of 2 to 10 cm, so that the force applied to the leg insertion opening during waist adjustment can be dispersed to the leg insertion part, thereby reducing excessive tightness at the leg insertion opening and improving comfort. The force generated when the lower end of the front depression at the front of the waist top is stretched by a unit length is greater than the force generated when it is stretched by a unit length at a front position that is in the same position in the up-down direction as the lower end of the rear depression, and the force generated when it is stretched by a unit length at the lower end of the rear depression is greater than the force generated when it is stretched by a unit length at a front position that is in the same position in the up-down direction as the lower end of the rear depression, and further, the force generated when it is stretched by a unit length at the lower end of the rear depression is greater than the force generated when it is stretched by a unit length at the lower end of the front depression at the front of the waist top, making it possible to straighten the forward-tilted pelvis, maintain correct posture, and eliminate arching of the lower back. Effect of the Invention

[0031] According to the present invention, it is possible to straighten the forward-tilted pelvis, maintain a correct posture, and eliminate arched lower back. [Brief description of the drawings]

In the following description, front / back, left / right, and top / bottom are defined as viewed from the front side when the lower leg garment 1 is worn by a human body 100, and each direction is shown in the drawings.

[0034] The outline of the lower limb clothing 1 of this embodiment will be described with reference to Figures 1 to 4. The lower limb clothing 1 has a waist top portion 10, a body portion 20, a pelvic belt portion 30, and a crotch portion 40, and has a leg insertion opening 50 at the lower end through which the leg portion 101 of a human body 100 is inserted.

[0035] The waist top portion 10 is arranged in a band-like manner around the waist portion 102 of the human body 100, and has a V-shaped rear depression 11 (hereinafter referred to as the rear depression 11) and a front depression 12 (hereinafter referred to as the front depression 12).

[0036] The rear recess 11 is provided at the upper end of the central part of the rear of the waist top 10, more specifically at the upper end, so as to be recessed downward. The rear recess 11 has a vertical depth dimension X of 4 to 13 cm. In addition, the angle α of the mutually opposing V-shaped inclined lines 11a of the rear recess 11 is 15° to 45° with respect to the horizontal direction. The upper end edge 11d of the lower end 11c of the rear recess 11 is configured to be located between the lower part of the fourth lumbar vertebra 100D of the human body 100 and the upper part of the sacrum 100F when worn on the human body 100. More specifically, the upper end edge 11d of the lower end 11c of the rear recess 11 is configured to be located between the intervertebral disc 100E' adjacent to the upper part of the fifth lumbar vertebra 100E of the human body 100 and the intervertebral disc 100F' adjacent to the lower part of the fifth lumbar vertebra 100E when worn on the human body 100.

[0037] The vertical depth dimension X of the rear recess 11 is set to be larger than the vertical depth dimension Y of the front recess 12.

[0038] The front recess 12 is provided at the upper part of the center of the front of the waist top part 10, more specifically at the upper end part, so as to be recessed downward. The front recess 12 has a vertical depth dimension Y of 0.1 to 1 cm, and is recessed slightly downward. The front recess is also slightly inclined, with the angle β of the V-shaped mutually opposing inclined lines 12a being 0.5° to 5° with respect to the horizontal direction. The upper end edge 10A' of the front of the waist top part 10, more specifically the upper end edge 10A' of the lower end part 12c of the front recess 12, is configured to be located above the navel of the human body 100 when worn on the human body 100.

[0039] That is, the upper edge 10A' of the front part of the waist top portion 10, i.e., the upper edge 10A' of the lower end portion 12c of the front depression portion 12, is configured to be positioned between the third lumbar vertebra 100C and the fourth lumbar vertebra 100D of the human body 100 when worn on the human body 100.

[0040] More specifically, the upper edge 10A' of the front part of the waist top portion 10, i.e., the upper edge 10A' of the lower end portion 12c of the front recess portion 12, is configured to be positioned between the lower part of the third lumbar vertebra 100C and the upper part of the fourth lumbar vertebra 100D of the human body 100 when worn on the human body 100.

[0041] In other words, in this embodiment, when worn on the human body 100, when the front upper edge 10A' of the waist top portion 10 is positioned between the third lumbar vertebra 100C and the fourth lumbar vertebra 100D of the human body 100, the upper edge 11d of the lower end 11c of the posterior recess portion 11 is configured to be positioned between the lower part of the fourth lumbar vertebra 100D of the human body 100 and the upper part of the sacrum 100F.

[0042] More specifically, in this embodiment, when worn on the human body 100, when the front upper edge 10A' of the waist top portion 100 is positioned between the lower part of the third lumbar vertebra 100C and the upper part of the fourth lumbar vertebra 100D of the human body 100, the upper edge 11d of the lower end 11c of the posterior recess portion 11 is configured to be positioned between the intervertebral disc 100E' adjacent above the fifth lumbar vertebra 100E of the human body 100 and the intervertebral disc 100F' adjacent below the fifth lumbar vertebra 100E.

[0043] Here, as shown in Figures 5 to 9, the waist top portion 10 is configured in a band shape by folding back the fabrics 10a1, 10a2, 10b, 10c via the folded back portions 10a1', 10a2', 10b', 10c' to overlap the fabrics 10a1, 10a2, 10b, 10c.

[0044] The waist top portion 10 is configured such that the folded-back portions 10a1′, 10a2′, 10b′, and 10c′ of the folded-back fabrics 10a1″, 10a2″, 10b″, and 10c″ form the upper end portions.

[0045] The depressions 11 and 12 can be formed by overlapping a plurality of folded fabrics 10a1'', 10a2'', 10b'', and 10c'' front to back so that they intersect with each other while inclining downward toward the positions where the depressions 11 and 12 are to be formed.

[0046] More specifically, the waist top portion 10 has a front waist top portion 10A, a left waist top portion 10B, and a right waist top portion 10C, with the front waist top portion 10A being provided at the front, the left waist top portion 10B being provided from the left side to the rear, and the right waist top portion 10C being provided from the right side to the rear.

[0047] That is, the front waist top portion 10A forms the front depression 12 by overlapping two folded fabrics 10a1″, 10a2″ front to back so that they intersect with each other while inclining downward in opposite directions toward the position where the front depression 12 is to be formed.

[0048] Here, the upper edge portions 10A' of the front and back overlapping portions of the front waist top portion 10A are not sewn to the opposing fabrics 10a1'', 10a2'', and are not connected to each other. In other words, the opposing fabrics 10a1'', 10a2'' of the front and back overlapping portions of the front waist top portion 10A can be separated from each other at the upper edge portions 10A'. The length of the unconnected portion in the front portion is 10 to 30 cm. The unconnected portion in the front portion is formed across the entire width of the front waist top portion 10A.

[0049] The left hip top portion 10B is formed by a single piece of folded fabric 10b'' that is inclined downward from the left side toward the center of the rear portion where the rear recess 11 is to be formed. The right hip top portion 10C is arranged in the opposite direction to the left hip top portion 10B, with a single folded fabric 10c'' sloping downward from the right side toward the center of the rear where the rear recess 11 is to be formed.

[0050] That is, the end 10B' of the left hip top portion 10B and the end 10C' of the right hip top portion 10C are overlapped front to back so as to cross each other at the center of the rear portion, forming the rear recessed portion 11. The left hip top portion 10B and the right hip top portion 10C are not sewn to the opposing fabrics 10b'', 10c'' at the upper end edges 10B'', 10C'' of the overlapping portions at the front and rear, respectively, and are not connected to each other. That is, the left hip top portion 10B and the right hip top portion 10C are capable of separating the opposing fabrics 10b'', 10c'' at the upper end edges 10B'', 10C'' of the overlapping portions at the front and rear. The ratio of the left-right length L1 of the unconnected portion at the front to the left-right length L2 of the unconnected portion at the rear (the left-right length L2 of the unconnected portion at either the left hip top portion 10B or the right hip top portion 10C) is 5 to 20.

[0051] The folded-back fabrics 10a1'', 10a2'', 10b'', and 10c'' (fabrics 10a1, 10a2, 10b, and 10c) of the waist top portion 10 may be made of a stretchable fabric. This stretchable fabric may be made of polyurethane fiber.

[0052] The stretch fabric (fold-over fabrics 10a1'', 10a2'', 10b'', 10c'') in this waist top portion 10 can be a mesh fabric, and the mesh fabric can be a power net. In addition, the stretch fabric can be a 1-way fabric that stretches in one direction.

[0053] The stretch directions of the folded fabrics 10a1'', 10a2'', 10b'', and 10c'' in the front hollow portion 12 and the back hollow portion 11 are directions that follow the slope of the waist top portion 10, as shown by the dotted arrows in the figure, and can be directions that intersect with each other at the overlapping portions.

[0054] In addition, the waist top portion 10 can be arranged so that a linear or band-shaped fabric 10d is sandwiched inside the folded-over fabric 10a1'', 10a2'', 10b'', 10c'', more specifically, inside the folded-over portions 10a1', 10a2', 10b', 10c' of the upper end portion (more specifically, the fabric 10d is arranged so as to be sandwiched inside the folded-over portions 10a1', 10a2', 10b', 10c' of the upper end portion, and is fixed by sewing to the inside of the fabric on the body side).

[0055] The linear or belt-like fabric 10d can be a stretchable fabric, which can be made of polyurethane fiber. The stretch direction can be the direction along which the waist top part 10 stretches, as shown by the dashed arrow in the figure.

[0056] The stretch fabric (fabric 10d) may be a 1-way fabric that stretches in one direction. The stretch fabric may be a stretch fabric, and the stretch fabric may be a stretch tape. The stretch fabric, more specifically, the stretch tape, is sandwiched between the insides of the folded-back portions 10a1', 10a2', 10b', and 10c', so that the tape does not bite into the human body 100 as much.

[0057] 10 to 13, the body portion 20 has a front body portion 20A, a left body portion 20B, and a right body portion 20C. The front body portion 20A is provided at the front of the body portion 20, the left body portion 20B is provided from the left side of the body portion 20 to the center of the rear, and the right body portion 20C is provided from the right side to the center of the rear.

[0058] The body portion 20 is formed by overlapping a plurality of stretchable fabrics. The body portion 20 is formed of stretchable fabrics, and the stretch direction includes a direction along a direction that slopes downward toward the center of the rear portion. More specifically, the body portion 20 includes a portion where the stretch direction of one overlapping stretchable fabric is one direction along a direction that slopes downward toward the center of the rear portion, or one vertical direction. Even more specifically, the body portion 20 includes a portion where the stretch direction of another overlapping stretchable fabric is two directions that intersect with each other (for example, two directions including the horizontal direction and the vertical direction). The body portion 20 includes a front body portion 20A, a left body portion 20B, and a right body portion 20C, which are configured as follows.

[0059] As shown in Fig. 10, the front body part 20A has a first front body part 20A1 (Fig. 10(a)), a second front body part 20A2 (Fig. 10(b)), and a third front body part 20A3 (Fig. 10(c)), and the first front body part 20A1, the second front body part 20A2, and the third front body part 20A3 are all the same shape. The front body part 20A is configured by overlapping the first front body part 20A1 as the outer fabric, the second front body part 20A2 as the inner fabric, and the third front body part 20A3 as the intermediate fabric sandwiched between the outer fabric and the inner fabric, so that the first front body part 20A1, the second front body part 20A2, and the third front body part 20A3 are positioned in the same order (Fig. 10(d)).

[0060] The front body portion 20A has an upper side 20a1, side sides 20a2 and 20a3, and a lower side 20a4. The side sides 20a2 and 20a3 each have a left side 20a2 and a right side 20a3.

[0061] That is, the upper side 20a1 is a curved line that protrudes downward and curves in an arc shape. The left side 20a2 and the right side 20a3 are inclined lines that slope in an inverted V shape so that the distance between them gradually decreases from top to bottom. The lower side 20a4 is a curved line that protrudes upward and curves in an arc shape.

[0062] The upper edge 20a1 is connected to the lower end 10A1 of the front waist top portion 10A, the left side edge 20a2 is connected to the first side edge 20b12 of the left body portion 20B described later, the right side edge 20a3 is connected to the first side edge 20c12 of the right body portion 20C described later, and the lower edge 20a4 is connected to the front edge 40a of the crotch portion 40 described later.

[0063] The first front body part 20A1, the second front body part 20A2, and the third front body part 20A3 constituting the front body part 20 can be made of a stretchable fabric, and the stretchable fabric of the first front body part 20A1 can be a 2-way fabric whose stretch directions intersect with each other. The stretchable fabric of the second front body part 20A2 and the third front body part 20A3 can be a 1-way fabric whose stretch direction is one direction.

[0064] The first front body portion 20A1 stretches in the horizontal (side) and vertical (up-down) directions as shown by the dashed-dotted arrows in the drawing, and the stretch directions cross at right angles. The second front body portion 20A2 and the third front body portion 20A3 stretch in the vertical direction (up-down direction) as indicated by the dashed-dotted arrow in the drawing.

[0065] The first front body portion 20A1, that is, the stretch fabric in the outer fabric, can be made of a 2-way tricot fabric formed by tricot knitting.

[0066] The stretch fabric of the second front body portion 20A2, i.e., the lining, can be a cotton blend fabric (plain stitch knit). By using a cotton blend fabric for the lining, it is possible to provide an excellent feel against the skin. The cotton blend fabric can be a fabric made by mixing cotton and polyester fibers.

[0067] The third front body portion 20A3, that is, the middle fabric, may be made of polyurethane fiber. The stretch fabric may be a mesh fabric, and the mesh fabric may be a power net.

[0068] As shown in Fig. 11, the left body portion 20B has a first left body portion 20B1 (Fig. 11(a)) and a second left body portion 20B2 (Fig. 11(b)). The left body portion 20B is formed by overlapping the first left body portion 20B1 and the second left body portion 20B2, with the first left body portion 20B1 serving as the outer fabric and the second left body portion 20B2 serving as the inner fabric (Fig. 11(c)).

[0069] As shown in Fig. 12, the right body portion 20C has a first right body portion 20C1 (Fig. 12(a)) and a second right body portion 20C2 (Fig. 12(b)).

[0071] The upper sides 20b11 and 20c11 are lines extending obliquely in the horizontal direction (sideways). The sides 20b12, 20b13 of the first left body part 20B1 have a first side 20b12 and a second side 20b13, and the sides 20c12, 20c13 of the first right body part 20C1 have a first side 20c12 and a second side 20c13. The first sides 20b12, 20c12 and the second sides 20b13, 20c13 are inclined lines that are inclined in a generally V-shape so that the distance between them gradually increases from top to bottom. The second sides 20b13, 20c13 are inclined lines that are inclined while curving from top to bottom.

[0072] The bottom side 20b14 of the first left body part 20B1 has a first bottom side 20b14', a second bottom side 20b14'', and a third bottom side 20b14''', and the bottom side 20c14 of the first right body part 20C1 has a first bottom side 20c14', a second bottom side 20c14'', and a third bottom side 20c14'''.

[0073] The first lower sides 20b14', 20c14' are located on the front side of the lower sides 20b14, 20c14, and are curved lines that protrude upward and curve in an arc shape. The second lower sides 20b14'', 20c14'' are located in the middle of the lower sides 20b14, 20c14, and are inclined lines that slope downward toward the rear side.

[0074] The third lower sides 20b14''', 20c14''' are on the rear side of the lower sides 20b14, 20c14, and are inclined lines that slope upward toward the rear end.

[0075] An upper edge 20b11 of the first left body portion 20B1 is connected to the lower end of the left hip top portion 10B, an upper edge 20c11 of the first right body portion 20C1 is connected to the lower end of the right hip top portion 10C, a first side edge 20b12 of the first left body portion 20B1 is connected to the side edge 20a2 of the front body portion 20A, and a first side edge 20c12 of the first right body portion 20C1 is connected to the lower end of the right hip top portion 10C. The body portion 20 is configured to be circumferential, with the side edge 20a3 of the body portion 20A being connected, the second side edge 20b13 of the first left body portion 20B1 being connected to the second side edge 20c13 of the first right body portion 20C1 being connected, and the second side edge 20b23 of the second left body portion 20B2 being connected to the second side edge 20c23 of the second right body portion 20C2 being connected.

[0076] The first lower sides 20b14', 20c14' and the second lower sides 20b14'', 20c14'' form a leg insertion opening 50, and the third lower sides 20b14''', 20c14''' are connected to the rear side 40d of the crotch portion 40.

[0077] The second left body portion 20B2 has an upper side 20b21, side sides 20b22 and 20b23, a lower side 20b24, and a curved line 20b25, and the second right body portion 20C2 has an upper side 20c21, side sides 20c22 and 20c23, a lower side 20c24, and a curved line 20c25.

[0078] The sides 20b22, 20b23, 20c22, 20c23 have first sides 20b22, 20c22 and second sides 20b23, 20c23. The bottom sides 20b24, 20c24 have second bottom sides 20b24″, 20c24″ and third bottom sides 20b24′″, 20c24′″.

[0079] The upper edges 20b21, 20c21 correspond to the upper edges 20b11, 20c11 of the first left body portion 20B1 and the first right body portion 20C1, and are lines that extend diagonally horizontally (sideways) so as to reach from the front ends to the middle portions of the upper edges 20b11, 20c11 of the first left body portion 20B1 and the first right body portion 20C1.

[0080] The first side edges 20b22, 20c22 form an inclined line that inclines in the opposite direction to the first side edges 20b12, 20c12 of the first left body portion 20B1 and the first right body portion 20C1 so as to draw an approximate triangle between the first side edges 20b12, 20c12 of the first left body portion 20B1 and the first right body portion 20C1 and the first bottom edges 20b14', 20c14' of the first left body portion 20B1 and the first right body portion 20C1, leaving the front side missing in an approximately triangular shape.

[0081] In other words, the missing, approximately triangular front side is a non-overlapping area with the first left body part 20B1 and the first right body part 20C1, and this area is configured to have only the first left body part 20B1 and the first right body part 20C1, without the second left body part 20B2 and the second right body part 20C2.

[0082] The second sides 20b23, 20c23 correspond to the second sides 20b13, 20c13 of the first left body portion 20B1 and the first right body portion 20C1, and are inclined lines that extend from the lower ends to the middle portions of the second sides 20b13, 20c13 of the first left body portion 20B1 and the first right body portion 20C1.

[0083] The lower edges 20b24, 20c24 have second lower edges 20b24'', 20c24'', and third lower edges 20b24'', 20c24'', corresponding to the second lower edges 20b14'', 20c14'', and third lower edges 20b14'', 20c14'', of the first left body portion 20B1 and the first right body portion 20C1, and the first lower edges corresponding to the first lower edges 20b14'', 20c14'', of the first left body portion 20B1 and the first right body portion 20C1 are missing.

[0084] The second bottom sides 20b24'', 20c24'' coincide with the second bottom sides 20b14'', 20c14'' of the first left body part 20B1 and the first right body part 20C1, and form an inclined line that slopes downward toward the rear as the intermediate portion of the bottom sides 20b24, 20c24.

[0085] The third bottom sides 20b24'''', 20c24'''' coincide with the third bottom sides 20b14'''', 20c14'''' of the first left body part 20B1 and the first right body part 20C1, and form an inclined line that slopes upward toward the rear end on the rear side of the bottom sides 20b24, 20c24.

[0086] The curved lines 20b25, 20c25 are curved lines that curve in an arc from the rear ends of the upper edges 20b21, 20c21 of the second left body portion 20B2 and the second right body portion 20C2 to the upper ends of the second side edges 20b23, 20c23 of the second left body portion 20B2 and the second right body portion 20C2, so as to correspond to the lower end of the buttocks of the human body 100 and to cut out the upper side of the rear portions of the left body portion 20B and the right body portion 20C in an approximately arc-shaped manner.

[0087] In other words, the missing upper side of the approximately arc-shaped portion is a non-overlapping area with the first left body portion 20B1 and the first right body portion 20C1, and this area is configured to have only the first left body portion 20B1 and the first right body portion 20C1, without having the second left body portion 20B2 and the second right body portion 20C2.

[0088] The upper sides 20b21, 20c21 are connected to the lower ends 10B1, 10C1 of the left and right hip top portions 10B, 10C, and the second side 20b23 of the second left body portion 20B2 is connected to the second side 20c23 of the second right body portion 20C2.

[0089] The second side 20b13 of the first left body part 20B1 and the second side 20c13 of the first right body part 20C1, and the second side 20b23 of the second left body part 20B2 and the second side 20c23 of the second right body part 20C2 are connected at the center of the back by sewing with a rubber-like thread 20D. This rubber-like thread 20D can be a rubber thread. The rubber-like thread 20D can be sewn so that the stretch direction is the up-down direction.

[0090] In addition, a stretchable stretch fabric 20E can be provided at a position overlapping with the stitching position of the rubber-like thread 20D. The stretch fabric 20E can be made of polyurethane fiber. The stretch direction of the stretch fabric 20E can be the up-down direction. The stretch fabric 20E can be a 1-way fabric that stretches in one direction, more specifically, the up-down direction. This stretch fabric 20E can be a stretch fabric, and the stretch fabric can be a stretch tape.

[0091] The second bottom edges 20b24'', 20c24'', together with the second bottom edge 20b14'' of the first left body portion 20B1 and the second bottom edge 20c14'' of the first right body portion 20C1, form the leg insertion opening 50, and the third bottom edges 20b24'', 20c24'''', together with the third bottom edge 20b14'''' of the first left body portion 20B1 and the third bottom edge 20c14'''' of the first right body portion 20C1, are connected to the rear end (rear edge 40d) of the crotch portion 40.

[0092] The first left body part 20B1, the second left body part 20B2, the first right body part 20C1, and the second right body part 20C2 may be made of a stretchable fabric.

[0093] The stretch fabric of the first left body portion 20B1 and the first right body portion 20C1 can be made of a 2-way tricot fabric formed by tricot knitting. The first left body portion 20B1 and the first right body portion 20C1 have stretch directions that are horizontal (sideways) and vertical (up and down) as indicated by the dotted arrows in the figure, and the stretch directions intersect at right angles.

[0094] The stretch fabric of the second left body part 20B2 and the second right body part 20C2 may be made of polyurethane fiber. Also, the stretch fabric of the second left body part 20B2 and the second right body part 20C2 may be made of mesh fabric, and the mesh fabric may be made of power net.

[0095] Furthermore, the stretch fabric of the second left body part 20B2 and the second right body part 20C2 can be a 1-way fabric that stretches in one direction, as shown by the dashed arrow in the figure, along the slope of the second bottom sides 20b24″, 20c24″ and along the slope of the left hip top part 10B and the right hip top part 10C, sloping downward toward the center of the back.

[0096] The pelvic belt portion 30 is configured in a belt-like shape as shown in FIG. 14(a). More specifically, it is configured in a belt-like shape that wraps around the pelvis on the upper side of the body portion 20, and is further layered on top of the body portion 20 as shown in FIG. 14(b) and FIG. 15.

[0097] More specifically, the pelvic belt portion 30 is provided on the upper side of the back surface side of the body portion 20, and has a front pelvic belt portion 30A, a left pelvic belt portion 30B, and a right pelvic belt portion 30C.

[0098] The front pelvic belt portion 30A is provided at the front of the pelvic belt portion 30, and is further provided overlapping the upper side of the back surface side of the front body portion 20A. The left pelvic belt portion 30B is provided from the left side to the rear of the pelvic belt portion 30, and is further provided overlapping the upper side of the back surface side of the left body portion 20B. The right pelvic belt portion 30C is provided from the right side to the rear of the pelvic belt portion 30, and is further provided overlapping the upper side of the back surface side of the right body portion 20C.

[0099] The pelvic belt portion 30 may be made of a stretchable fabric, which may be made of polyurethane fibers. The stretchable fabric may be a one-way fabric whose stretch direction is one direction. The stretch direction of the pelvic belt portion 30 includes a direction inclining downward toward the center of the back as shown by the dashed arrow in the figure, and this direction (the direction inclining downward toward the center of the back) may overlap with the stretch direction of the left body portion 20B and the right body portion 20C.

[0100] More specifically, the stretch direction of the front pelvic belt part 30A is the horizontal direction (side) that overlaps with the horizontal direction (side) of the stretch direction of the front body part 20A, as shown by the dashed arrow in the figure. The stretch direction of the left pelvic belt part 30B is the direction that slopes downward toward the center of the back part along the slope of the left hip top part 10B, as shown by the dashed arrow in the figure, and overlaps with the stretch direction of the left body part 20B. The stretch direction of the right pelvic belt part 30C is the direction that slopes downward toward the center of the back part along the slope of the right hip top part 10C, as shown by the dashed arrow in the figure, and overlaps with the stretch direction of the right body part 20C.

[0101] The stretch fabric may be made of polyurethane fiber. The stretch fabric may be a mesh fabric, and the mesh fabric may be a power net.

[0102] As shown in Fig. 16, the crotch portion 40 is provided to extend in the front-rear direction so as to correspond to the crotch of the human body 100. The crotch portion 40 has a first crotch portion 41 (Fig. 16(a)) and a second crotch portion 42 (Fig. 16(b)), and the second crotch portion 42 has the same shape as the first crotch portion 41. The crotch portion 40 is configured such that the first crotch portion 41 is the outer fabric and the first crotch portion 42 is the inner fabric, and the first crotch portion and the second crotch portion are overlapped so that their positions match (Fig. 16(c)).

[0103] The crotch portion 40 has a front edge 40a, a first side edge 40b, a second side edge 40c, and a rear edge 40d.

[0104] The front side 40a is a curved line that protrudes forward and curves in an arc. The first side 40b and the second side 40c are curved lines that protrude inward and curve in an arc so that the distance between them gradually increases from the front to the rear. The rear side 40d is a curved line that protrudes backward and curves in an arc.

[0105] The front edge 40a is connected to the bottom edge 20a4 of the front body portion 20A, the first side edge 40b and the second side edge 40c, together with the first bottom edges 20b14', 20b24', 20c14', 20c24' and second bottom edges 20b14'', 20b24'', 20c14'', 20c24'' of the left body portion 20B and the right body portion 20C, form a leg insertion opening 50, and the rear edge 40d is connected to the third bottom edges 20b14'''', 20b24'''', 20c14'''', 20c24'''' of the left body portion 20B and the right body portion 20C.

[0106] The first crotch section 41 and the second crotch section 42 may be made of a stretchable fabric. The stretchable fabric of the first crotch section 41 may be made of a 2-way tricot fabric formed by tricot knitting. The stretch directions of first crotch portion 41 are horizontal (sideways) and vertical (up-down) as shown by the dashed-dotted arrows in the figure, and the stretch directions intersect at right angles.

[0107] The stretch fabric of the second crotch region 42 may be a 1-way fabric that stretches in one direction. The stretch direction of the first crotch region 41 is the horizontal direction (sideways) as shown by the dashed arrow in the figure.

[0108] The stretch fabric of the second crotch portion 42, i.e., the stretch fabric of the lining, can be a cotton blend fabric (plain stitch knit). By using a cotton blend fabric for the lining, it is possible to provide an excellent feel against the skin. The cotton blend fabric can be a fabric made by mixing cotton and polyester fibers.

[0109] As is clear from the above, the crotch section 40 is formed by overlapping a plurality of stretchable stretch fabrics. In the crotch section 40, the stretch direction of one of the overlapping stretch fabrics is the lateral direction. In addition, in the crotch section 40, the stretch directions of the other overlapping stretch fabrics are two directions that intersect with each other.

[0110] The leg insertion opening 50 is provided to correspond to the base of the leg 101 of the human body 100. The leg insertion opening 50 can be formed to be surrounded by the first lower sides 20b14', 20b24', 20c14', 20c24' and the second lower sides 20b14'', 20c14'' of the left body portion 20B and the right body portion 20C, and the first side side 40b and the second side side 40c of the crotch portion 40.

[0111] The leg insertion opening 50 is connected to the leg insertion part 60. The leg insertion part 60 extends downward from the leg insertion opening 50. The leg insertion part 60 has a vertical dimension of 2 to 10 cm and is made of a stretchable fabric.

[0112] The stretch fabric of the leg insertion part 60 may be made of polyurethane fiber. The stretch fabric of the leg insertion part 60 may be a stretch fabric. The stretch fabric may be a stretch lace. The stretch fabric of the leg insertion part 60 may be a 1-way fabric that stretches in one direction.

[0113] As described above, according to the present invention, the upper part of the central part of the rear of the waist top part 10 has a recess 11 that recesses downward, so that the central part of the front of the waist top part 10 can be pushed upward from below, and the central part of the rear of the waist top part 10 can be pushed downward from above along the sacrum. This makes it possible to correct the waist part 102 of the human body 100 by pulling it downward and rearward, and it is possible to straighten the forward-tilted pelvis, maintain a correct posture, and eliminate arched lower back (Fig. 17).

[0114] In addition, the upper edge 10A' at the front of the waist top portion 10 is positioned above the navel of the human body 100 when the seat is attached to the human body 100, so that the side above the navel of the human body 100 is pulled downward and behind the waist portion 102, making it possible to straighten the tilted pelvis.

[0115] Furthermore, the upper end edge 10A' of the front part of the waist top portion 10 is configured to be located between the third lumbar vertebra 100C and the fourth lumbar vertebra 100D of the human body 100 when worn on the human body 100; more specifically, it is configured to be located between the lower part of the third lumbar vertebra 100C and the upper part of the fourth lumbar vertebra 100D of the human body 100 when worn on the human body 100. Therefore, the excessive lumbar forearm that has been augmented by the forward tilt of the pelvis can be corrected so that it is closer to the normal lumbar forearm, and the forward tilted pelvis can be straightened.

[0116] Furthermore, the upper edge 11d of the lower end 11c of the rear recess 11 is configured to be located between the lower part of the fourth lumbar vertebra 100D of the human body 100 and the upper part of the sacrum 100F when the human body 100 is worn; more specifically, it is configured to be located between the intervertebral disc 100E' adjacent above the fifth lumbar vertebra 100E of the human body 100 and the intervertebral disc 100F' adjacent below the fifth lumbar vertebra 100E when the human body 100 is worn. This makes it possible to correct excessive lumbar forearms that have been strengthened by the forward tilt of the pelvis so that they are closer to normal lumbar forearms.

[0117] Furthermore, since the depth dimension X of the rear recess 11 is set to 4 to 13 cm, the upper edge 11d of the lower end 11c of the rear recess 11 can be positioned below the fifth lumbar vertebra of the human body 100 when the brace is worn on the human body 100.

[0118] In addition, the rear recess 11 is formed in a V-shape, and the angle α of the mutually opposing inclined lines 11a of the V-shape is set to 15° to 45° with respect to the horizontal direction, so that the inclined lines 11a can smoothly straighten the forward-tilted pelvis.

[0119] Furthermore, since the body portion 20 is formed from a stretchable fabric, and the stretch direction includes a direction that slopes downward toward the center of the back portion, it is possible to further correct the waist portion 102 by pulling it downward and rearward.

[0120] Furthermore, the pelvic belt portion 30 is made of a stretchable fabric, and the stretch direction of the pelvic belt portion 30 includes a direction that slopes downward toward the center of the rear, and this direction overlaps with the stretch direction of the left body portion 20B and the right body portion 20C, so that it is possible to further correct the waist portion 102 by pulling it downward and rearward.

[0121] Furthermore, a downwardly recessed portion 12 is provided in the upper central portion of the front part of the waist top part 10, so that it is possible to correct the waist part 102 by pulling it further downward and rearward at the rear part of the waist top part 10 while applying stress to the front recessed portion 12, thereby improving the effect of correcting the waist part 102.

[0122] Furthermore, the depth dimension X of the rear recess 11 of the waist top portion 10 is set to a dimension larger than the depth dimension Y of the front recess 12 of the waist top portion 10, so that the waist portion 102 can be reliably corrected.

[0123] Furthermore, since the depth dimension Y of the front hollow portion 12 is set to 0.1 to 1 cm, the effect of correcting the waist portion 102 can be increased.

[0124] Furthermore, the front depression 12 is formed in a V-shape, and the angle β of the opposing inclined lines 12a of the V-shape is set to 0.5° to 5° with respect to the horizontal direction, thereby further increasing the effect of correcting the waist region 102.

[0125] Furthermore, the waist top section 10 has a front waist top section 10A at the front, a left waist top section 10B at the left side and rear, and a right waist top section 10C at the right side and rear, and the front waist top section 10A is made by overlapping at least two pieces of fabric in a downward inclination and crossing each other, forming a front recessed section 12, and the upper edge section 10A' of the overlapping front and rear sections is not connected to the opposing fabric, so that the non-connected front section can shift according to the body shape when worn, improving the fit. Also, the non-connected front section prevents excessive tightening, improving the comfort of wearing.

[0126] Furthermore, the fabric of the left hip top 10B is angled downward from the left side toward the center of the back, and the fabric of the right hip top 10C is angled downward from the right side toward the center of the back, and end 10B' of left hip top 10B and end 10C' of right hip top 10C are overlapped front to back so as to cross each other, forming rear depression 11, and the upper edge portions 10B", 10C" of the overlapped front and rear portions are not connected to the opposing fabric, so that the unconnected portion at the back can shift according to the body shape when worn, improving the fit. Also, the unconnected portion at the back can be prevented from being excessively tight, improving comfort.

[0127] Furthermore, the length of the non-connected portion in the front is set to 10 to 30 cm, which can reliably improve the fit and comfort.

[0128] Furthermore, the non-connected portion in the front part is formed across the entire area in the left-right direction of the front waist top part 10A, so that the fit and comfort can be further improved.

[0129] Furthermore, the ratio of the left-right length of the unconnected portion in the front to the left-right length of the unconnected portion in the rear is set to 5 to 20, thereby further improving the fit and comfort.

[0130] In addition, the body portion 20 is formed by overlapping a plurality of stretchable stretch fabrics, and includes a portion in which the stretch direction of one stretch fabric is one direction along the direction inclining downward toward the center of the rear portion, and the stretch direction of the other stretch fabric is two mutually intersecting directions, so that it is possible to correct the waist portion 102 by increasing the stretch force of the one stretch fabric stretching in one direction and pulling it further downward, and the other stretch fabric stretching in two directions makes it easier to stretch according to the body shape, improving the fit. In addition, the other stretch fabric stretching in two directions can prevent excessive tightening and improve the comfort of wearing (in a 1WAY fabric with a stretch direction in one direction, the stretch force is concentrated without being dispersed in multiple directions, so the stretch force is relatively large and a relatively large force is required to stretch, whereas in a 2WAY fabric with a stretch direction in two directions, the stretch force is dispersed in multiple directions, so the stretch force is relatively small and a relatively small force is required to stretch).

[0131] Furthermore, the leg insertion opening 50 is connected to the leg insertion part 60, which extends downward from the leg insertion opening 50 and is made of a stretchable fabric with a width of 2 to 10 cm, so that the force applied to the leg insertion opening 50 during adjustment of the waist 102 can be distributed to the leg insertion part 60. This can alleviate excessive tightness at the leg insertion opening 50 and improve comfort.

[0132] Furthermore, the first sides 20b22, 20c22 of the second left body portion 20B2 and the second right body portion 20C2 are arranged so as to draw a substantially triangle between the first sides 20b12, 20c12 of the first left body portion 20B1 and the first right body portion 20C1 and the first bottom sides 20b14', 20c14' of the first left body portion 20B1 and the first right body portion 20C1, and the front side is cut out in a substantially triangular shape. The inclined line slopes in the opposite direction to the sides 20b12, 20c12, and the missing approximately triangular front side is a non-overlapping area with the first left body part 20B1 and the first right body part 20C1, and this area is configured to have only the first left body part 20B1 and the first right body part 20C1.This reduces the stretching force and reduces the restriction of the movement of the user wearing the lower leg garment 1 at the missing approximately triangular front side.

[0133] Furthermore, the second left body portion 20B2 and the second right body portion 20C2 have curved lines 20b25, 20c25, which are curved in an arc shape so as to correspond to the lower end of the buttocks of the human body 100 and to cause the upper side of the rear of the left body portion 20B and the right body portion 20C to be missing in an approximately arc shape, and the missing approximately arc-shaped upper side is curved in an arc shape so as to correspond to the lower end of the buttocks of the human body 100 and cause the upper side of the missing approximately arc shape to be missing in an approximately arc shape. As a non-overlapping area with the right body portion 20C1, this area is configured to have only the first left body portion 20B1 and the first right body portion 20C1. This reduces the stretching force and reduces the restriction of movement of the buttocks of the user wearing the lower limb garment 1 at the missing upper side of the approximately arc-shaped portion, and allows the curved lines 20b25, 20c25 to lift and hold the buttocks (Figure 17).

[0134] Furthermore, the second side 20b13 of the first left body portion 20B1 and the second side 20c13 of the first right body portion 20C1 are connected by sewing with a rubber-like thread 20D, and a stretchable fabric 20E that is stretchable in the vertical direction is provided at a position overlapping with the sewing position of the rubber-like thread 20D, so that it is possible to further correct the waist region 102 by pulling it downward.

[0135] Furthermore, in areas where the stretch fabric is a 1-way fabric that stretches in one direction, the stretch force is not dispersed in multiple directions, and the stretch force can be improved.

[0136] Furthermore, by configuring the lower limb garment 1 of the present invention as in the above embodiment, it is possible to increase the ratio R of the radius of curvature R2 of the arc shape approximating the curve connecting the tip of the spinous process 100A1 of the first lumbar vertebra 100A to the tip of the spinous process 100E1 of the fifth lumbar vertebra 100E after the garment is worn on the human body 100 from 1.3 to 2.5, as shown in Figure 18. This allows the forward tilted pelvis to be comfortably straightened. [Number 1] R=R2 / R1

[0137] Here, the present invention is not limited to the above-described embodiment, and various modifications and applications are possible without departing from the scope of the claims.

[0138] For example, in the embodiment described above, the front waist top portion 10A is formed by overlapping two pieces of folded fabric 10a1'', 10a2'' front and back so that they are inclined downward in opposite directions and cross each other, forming the front recessed portion 12, but the required effect can also be achieved by overlapping two or more pieces of folded fabric. In other words, the front waist top portion 10A can also achieve the required effect by forming the front recessed portion 12 by overlapping at least two pieces of folded fabric 10a1'', 10a2'' front and back so that they are inclined downward in opposite directions and cross each other.

[0139] [Comparative Example] Comparative examples of the present invention are shown in Figures 19 and 20. That is, the comparative examples of the present invention show a comparison between the lower leg garment 1 of the present invention in Figures 19(a) and 20(a) and an example of conventional lower leg garment 1 in Figures 19(a) and 20(a).

[0140] In other words, the lower leg clothing 1 of the present invention in Figures 19(a) and 20(a) is 5 cm higher in height (the heightwise position of the upper edge 10A' of the lower end 12c of the front depression 12 of the front depression 10) and 3 cm lower in height than the conventional lower leg clothing 1 in Figures 19(a) and 20(a).

[0141] As a result, the upper edge 10A' of the front part of the waist top portion 10 is located above the third lumbar vertebra of the human body 100 when worn on the human body 100, and the upper edge 11d of the lower end portion 11c of the rear recessed portion 11 is located below the fifth lumbar vertebra of the human body 100 when worn on the human body 100, thereby improving the corrective effect compared to conventional lower limb clothing 1 (there was a demand for a further improvement in the corrective effect of conventional lower limb clothing 1).

[0142] However, as a result of improving the corrective effect in this way, the feeling of tightness on the human body 100 increases, which affects the fit and comfort of the garment.

[0143] For this reason, in the lower leg garment 1 of the present invention, the upper edge portions 10A', 10B', 10C' of the front and rear overlapping portions are not connected to the opposing fabrics in the rear hollow portion 11 and the front hollow portion 12. This allows the non-connected portions to shift according to the body shape when worn, improving the fit and comfort.

[0144] Furthermore, in the lower leg garment 1 of the present invention, the body portion 20 and the crotch portion 40 are made of a 2-way fabric that stretches in two intersecting directions, which allows the garment to stretch easily according to the body shape, further improving the fit and comfort.

[0145] Furthermore, in the lower leg garment 1 of the present invention, the leg insertion part 60 is provided with a width of 2 to 10 cm, and is made of a stretchable fabric. This makes it possible to alleviate excessive tightening at the leg insertion opening 50 and improve comfort (it has been pointed out that in conventional lower leg garments 1, the tightening force at the leg insertion opening 50 is too strong due to the correction effect).

[0146] In addition, when the lower limb garment 1 of the present invention was worn by a user, the force (spring constant) generated when stretched by a unit length was measured at the lower end 12c of the front depression 12 at the front of the waist top 10 (position a in Figure 19(a)), at a front position that is the same position in the vertical direction as the lower end 11c of the rear depression 11 (position b in Figure 19(a)), and at the lower end 11c of the rear depression 11 at the waist top 10 (position b' in Figure 20(a)), as shown in Figure 21.

[0147] As a result, the force (spring constant ka) generated when the lower end 12c (position a in FIG. 19(a)) of the front recess 12 in the front of the waist top 10 is stretched by a unit length is 0.233 N / mm, the force (spring constant kb) generated when the front position (position b in FIG. 19(a)) which is the same position in the vertical direction as the lower end 11c of the rear recess 11 is stretched by a unit length is 0.197 N / mm, The force (spring constant kb') generated when the lower end 11c of the rear recess 11 (position b' in Figure 20(a)) is stretched by a unit length was 0.273 N / mm. Also, the force ka' generated when the lower end 11c of the rear recess 11 is stretched by a unit length at a rear position (position a' in Figure 20(a)) which is the same position in the vertical direction as the lower end 12c of the front recess 12 at the front of the waist top 10 is stretched by a unit length is of course 0 because no fabric is provided at that position.

[0148] That is, the force ka generated when the lower end 12c of the front depression 12 in the front of the waist top portion 10 (position a in FIG. 19(a)) is stretched by a unit length is greater than the force kb generated when the lower end 12c is stretched by a unit length at a front position (position b in FIG. 19(a)) that is the same position as the lower end 11c of the rear depression 11 in the up-down direction, and the force kb' generated when the lower end 11c of the rear depression 11 is stretched by a unit length (position b in FIG. 19(a)) is greater than the force kb generated when the lower end 11c of the rear depression 11 is stretched by a unit length at a front position (position b in FIG. 19(a)) that is the same position as the lower end 11c of the rear depression 11 in the up-down direction, and further The force kb' generated when stretching by a unit length at (position b' in Figure 20(a)) is greater than the force ka generated when stretching by a unit length at the lower end 12c of the front depression 12 at the front of the waist top 10 (position a in Figure 19(a)); and further, the force ka generated when stretching by a unit length at the lower end 12c of the front depression 12 at the front of the waist top 10 (position a in Figure 19(a)) is greater than the force ka' generated when stretching by a unit length at the rear position (position a' in Figure 20(a)) which is the same position in the vertical direction as the lower end 12c of the front depression 12.This makes it possible to straighten the forward-tilted pelvis, maintain correct posture, and eliminate arching of the lower back.

[0149] Here, ka and kb can be obtained by subtracting a predetermined length M1 from a force B1 generated at positions a and b when the lower leg garment 1 of the present invention is pulled forward by a predetermined length M1 at positions a and b while the lower leg garment 1 of the present invention is worn by a user. Also, kb' can be obtained by subtracting a predetermined length M2 from a force B2 generated at position b' when the lower leg garment 1 of the present invention is pulled backward by a predetermined length M2 at position b' while the lower leg garment 1 of the present invention is worn by a user.
