[0010] The athletic clothing according to the present invention is, for example, an athletic brassiere (hereinafter also referred to as "sports bra"), and any athletic clothing that covers the left and right chests is acceptable. For example, the athletic clothing may be a swimsuit, a tank top, a camisole, or the like.

[0011] Figures 1 to 3 are respectively a front view, a rear view, and a perspective view of the sports bra 1 according to the present invention in a worn state. Hereinafter, the up-down, left-right, and front-back directions of the sports bra 1 are defined based on the upright state of a wearer wearing the sports bra 1. Further, the direction from the outer surface toward the inside in the thickness direction of the fabric is defined as the inner surface side, and the opposite direction is defined as the outer surface side; the direction toward the outside in the width direction is defined as the outer side, and the direction toward the center in the width direction is defined as the inner side.

[0012] Referring to Figures 1 to 3, the sports bra 1 is formed of, for example, a fabric or a knit fabric. The sports bra 1 includes a main body portion 2 that covers the chest of a wearer 9, a connecting portion 3 that connects both side portions of the main body portion 2 through the back side of the wearer 9, a torso portion 4 connected to the lower ends of the main body portion 2 and the connecting portion 3, and a pair of left and right shoulder straps 5 stretched across the main body portion 2 and the connecting portion 3. The main body portion 2 and the connecting portion 3 respectively refer to portions located on the front side and the back side of the wearer 9, and are divided at both outer sides in the width direction. The pattern before sewing constituting the sports bra 1 does not necessarily have to be formed so as to match the division of the main body portion and the connecting portion, the main body portion and the connecting portion may include two or more patterns, and the main body portion and the connecting portion may be formed integrally.

[0013] In the present specification, the bust line BL, underbust line UL, and anterior axillary point 91 each comply with the provisions of JIS L011:2006 (Body terminology for apparel). The bust line BL is the intersection line between the horizontal plane passing through the center point of the nipple (also referred to as nipple point and bust top) and the body surface. The underbust line UL is the intersection line between the horizontal plane directly below the breasts of a woman and the body surface. The anterior axillary point 91 is the point at the upper end of the anterior axillary fissure (the upper end of the armpit wrinkle). Body measurement is, for example, performed with the subject in an upright posture where both arms are naturally drooped, knees are straightened, the left and right heels are brought together, and the toes are slightly opened. Furthermore, for each of the above lines and points, the bust line BL, underbust line UL, and anterior axillary point 91 of a predetermined mannequin (mannequin manufactured by Nanairo Co., Ltd.: WD-20A (for women)) when the sports bra 1 is put on said mannequin may be applied.

[0014] The main body portion 2 has a double-layer structure including an outer fabric 21 positioned on the front side of the wearer and a lining fabric 22 positioned on the back side (body side). The outer fabric 21 and the lining fabric 22 are in the form of a bag sewn together at the peripheral edge, and a space for inserting a pad (not shown) is formed between the outer fabric 21 and the lining fabric 22.

[0015] Figure 4 is a developed view of the main body portion 2. In a front view, the main body portion 2 has a substantially trapezoidal shape that is flattened in the vertical direction. A neckline portion 21b formed by notching the upper end portion 21a downward is provided at the widthwise central portion of the upper end portion 21a. On both side portions of the main body portion 2, there are provided both side edge portions 21c that incline outward in the width direction upward from the lower edge portion 21e of the main body portion 2, and armhole portions 21d that incline inward in the width direction upward from the upper ends of the both side edge portions 21c. The lower edge portion 21e is curved such that the center in the width direction is positioned higher than both side portions.

[0016] As shown in Figure 3, when the main body portion 2 and the connecting portion 3 are sewn together and the lower edge portion 21e extends in the horizontal direction, the widthwise central portion of the main body portion 2 deforms in a direction away from the wearer. As a result, a breast accommodating space for the wearer is formed in the main body portion 2.

[0017] As shown in Figure 2, the connecting portion 3 has a double-layered structure, consisting of an outer fabric 31 located on the back side of the wearer and a lining 32 located on the back side (body side). For illustrative purposes, the outlines of the outer fabric 31 and lining 32 are shown offset, but the outlines of the outer fabric 31 and lining 32 may coincide. In this embodiment, the main body portion 2 and the connecting portion 3 are sewn together at the side seam SL. The torso portion 4 is made of an elastic material such as rubber, and the elasticity of the torso portion 4 makes it easier for the sports bra 1 to fit around the torso below the bust of the wearer 9.

[0018] The outer fabrics 21 and 31 of the main body 2 and connecting parts 3 are made of a first stretchable fabric and have a predetermined compression. The first stretchable fabric constituting the main body 2 and connecting parts 3 is, for example, a special fabric made by combining nylon and polyester, and the elongation rate within the fabric can be changed by dissolving only the polyester in a special solvent at a predetermined position. The first stretchable fabric is intended to be worn in close contact with the wearer. Preferably, the stress of the first stretchable fabric when stretched by 30% in the body length direction is 2.0 N or more and 3.0 N or less, and in this embodiment, for example, it is 2.5 N. Preferably, the stretch-side stress of the first stretchable fabric when stretched by 30% in the body width direction is 2.1 N or more and 3.1 N or less, and in this embodiment, for example, it is 2.6 N.

[0019] The stress of the first stretchable fabric during elongation in both the length and width directions was measured by preparing the outer fabric 21 of the main body 2, setting grip widths of 25 mm at the top and bottom, and fixing it to a tensile testing machine (Shimadzu Corporation: Autograph AGS-X) so that the grip spacing was 90 mm, stretching it at a tensile speed of 200 mm / min, and reading the stress when the elongation rate was 30%, which was defined as the "elongation stress". The first stretchable fabric from which the tensile stress was measured corresponds to the fabric located on the front side of the wearer and covering the chest, and more specifically, as shown in Figure 1, it corresponds to a test piece cut from the front upper portion a located above the chest of the wearer 9 in the main body 2. The front upper portion a is the area above the bust line BL and inside the midpoint of the wearer 9's clavicle in the width direction.

[0020] As shown in Figures 2 and 3, the pair of left and right shoulder straps 5 have a left shoulder strap 51 positioned on the wearer's left shoulder and a right shoulder strap 52 positioned on the wearer's right shoulder. The left and right shoulder straps 51 and 52 are connected to the upper left end 21a or the upper right end 21a of the main body 2 and to the central part 31a in the width direction of the connecting part, respectively. In this embodiment, the rear ends of the left shoulder strap 51 and the right shoulder strap 52 are connected by the center line CL on the back. In this embodiment, the left and right shoulder straps 51 and 52 are each composed of two strip-shaped members having a predetermined width, and are so-called double straps.

[0021] As shown in Figure 4, the main body 2 is provided with a pair of left and right first reinforcing members 6 that extend vertically on both sides, and a pair of left and right second reinforcing members 7 that are connected to the first reinforcing members 6 and are positioned along the armhole portion 21d under the armpit of the wearer 9. Since each of the first reinforcing members 6 and each of the second reinforcing members 7 is arranged symmetrically, only the left first and second reinforcing members 6 and 7 will be described, and the description of the right first and second reinforcing members 6 and 7 will be omitted.

[0022] In this embodiment, the first reinforcing member 6 has a substantially triangular main reinforcing member 61 and a sub-reinforcing member 62 that overlaps with at least a part of the main reinforcing member 61.

[0023] In this embodiment, the first and second reinforcing members 6 and 7 are made of a second stretchable fabric that is harder than the outer fabric 21 (has a higher stress at 30% elongation). More specifically, the first and second reinforcing members 6 and 7 preferably have a higher stress at 30% elongation than the outer fabrics 21 and 31, preferably between 10.4 N and 15.6 N, for example, 13.0 N. The stress of the first reinforcing member 6 and the second reinforcing member 7 at 30% elongation is the elongation rate in the longitudinal direction indicated by arrows A1 and A2 in Figure 4, respectively. In this embodiment, the second stretchable fabric is a fabric whose elongation rate is increased by dissolving only the polyester of the first stretchable fabric in a special solvent.

[0024] The first reinforcing member 6 is attached to the main body 2 via hot melt HM. The stress at 30% elongation of the first reinforcing portion b1 in the main body 2 where the first reinforcing member 6 is located is preferably 15N or more and 51N or less, for example, 30N. In the first reinforcing portion b1 in the main body 2, the surface fabric 21, hot melt HM, and the first reinforcing member 6 are laminated in this order on the inner surface side of the surface fabric 21. The stress at 30% elongation of the first reinforcing portion b1 is the elongation rate in the longitudinal direction shown by arrow A1 in Figure 4.

[0025] The first reinforcing member 6 has a first three-layer reinforcing portion b2 in which a sub-reinforcing member 62 is further attached to the inner surface side of the main reinforcing member 61 via hot melt HM. The first three-layer reinforcing portion b2 is made up of the main body 2, hot melt HM, main reinforcing member 61, hot melt HM, and sub-reinforcing member 62, which are laminated in this order.

[0026] The stress at 30% elongation in each part of the main body 2 is increased in the following order: outer fabric 21, first reinforcement part b1, and first three-layer reinforcement part b2.

[0027] The main reinforcing member 61 is substantially triangular in shape and has a main lower side 61a along the lower edge 21e of the main body 2, a main hypotenuse 61b that slopes outward in the width direction upward from the inner end of the main lower side 61a in the width direction, a main upper side 61c that slopes outward in the width direction downward from the upper end of the main hypotenuse 61b, and a main vertical side 61d that slopes inward in the width direction downward from the lower end of the main upper side 61c and connects to the outer end 61f of the main lower side 61a in the width direction. The width of the main upper side 61c of the main reinforcing member 61 is smaller than the width of the main lower side 61a, and the width dimension decreases from the main lower side 61a to the main upper side 61c.

[0028] The main lower edge 61a has a width W1 that is approximately 1 / 3 of the front half width W, which is the distance from the center line CL to the side line SL of the main body 2. The main lower edge 61a is located in the middle portion of the region obtained by dividing the front half width W into three equal parts. The inner end 61e of the main lower edge 61a is located outside the width W1 from the center line CL, and the outer end 61f of the main lower edge 61a is located inside the width W1 from the side line SL.

[0029] The main upper edge 61c is positioned along the armhole portion 21d of the main body portion 2, and is located on the side of the side seam SL side of the portion where the left and right shoulder straps 51 and 52 are connected at the upper end portion 21a. More specifically, the main upper edge 61c is located outward in the width direction from the outer end 61f of the main lower edge 61a. The main reinforcing member 61 as a whole is positioned outward from the center W0 of the front half width W.

[0030] The angle α between the main lower side 61a and the main hypotenuse 61b is preferably 30 degrees or more and 60 degrees or less, for example, 45 degrees. The angle α may also be the inclination angle α of the main hypotenuse 61b with respect to the lower edge portion 21e that extends outward in the width direction from the inner end 61e of the main lower side 61a.

[0031] The ratio of the area S1 of the main reinforcing member 61 to half the area 1 / 2S of the main body 2 is preferably 6.9% to 29%, for example, 12.4%. In this embodiment, since the sports bra 1 is symmetrical, the ratio may also be the ratio of the area S1 × 2 of the pair of left and right main reinforcing members 61 to the total area S of the main body 2.

[0032] The sub-reinforcement member 62 is triangular in shape and is positioned overlapping the main reinforcement member 61. The sub-reinforcement member 62 has an area of ​​approximately half or less of that of the main reinforcement member 61. The sub-reinforcement member 62 has a sub-lower side 62a along the lower edge 21e, a sub-slanted side 62b that slopes outward in the width direction upward from the inner end of the sub-lower side 62a, and a sub-vertical side 62c that slopes inward in the width direction downward from the upper end of the sub-slanted side 62b.

[0033] The sub-lower edge 62a is positioned along the main lower edge 61a, and the sub-vertical edge 62c is positioned along the main vertical edge 61d. The inner end 62d of the sub-lower edge 62a is located wider than the inner end 61e of the main lower edge 61a, and the outer end 62e of the sub-lower edge 62a coincides with the outer end 61f of the main lower edge 61a. The upper end 62f of the sub-vertical edge 62c is located below the main upper edge 61c and on the main vertical edge 61d.

[0034] The angle β between the sub-lower edge 62a and the sub-hypotenuse 62b is preferably between 15 degrees and 45 degrees, for example, 30 degrees. Each β may be the inclination angle β of the sub-hypotenuse 62b with respect to the lower edge portion 21e that extends outward in the width direction from the inner end 62d of the sub-lower edge 62a. In this embodiment, angle β is set to be smaller than angle α.

[0035] As shown in Figure 4, the width W3 of the second reinforcing member 7 is preferably 10 mm or more and 20 mm or less, for example, it is a long, strip-shaped member having a width of 20 mm. The second reinforcing member 7 slopes outward in the width direction downward along the armhole portion 21d from the upper end portion 21a of the main body portion 2 where the left and right shoulder straps 51 and 52 are attached, and terminates at the side seam SL (side edge portion 21c of the main body portion 2).

[0036] The second reinforcing member 7 is attached to the main body 2 via hot melt HM. The stress at 30% elongation of the second reinforcing portion b3 where the second reinforcing member 7 is located in the main body 2 is, overall, the same as the stress at 30% elongation of the first reinforcing portion b1 where the first reinforcing member 6 is located.

[0037] The first reinforcing member 6 is connected to the middle portion of the second reinforcing member 7. In this embodiment, the angle γ formed by the main hypotenuse 61b and the second reinforcing member 7 is preferably 70 degrees or more and 120 degrees or less, for example, set to 100 degrees. The second reinforcing member 7 has a second three-layer reinforcing portion b4 which overlaps at least a part with the upper end portion 61i of the first reinforcing member 6. The second three-layer reinforcing portion b4 is composed of the surface fabric 21 of the main body 2, hot melt HM, the main reinforcing member 61, hot melt HM, and the second reinforcing member 7.

[0038] The vertical length of the sub-reinforcement member 62 is set so as not to overlap with the second three-layer reinforcement portion b4. The second reinforcement member 7 and the sub-reinforcement member 62 are spaced apart, and the distance L1 between the second reinforcement member 7 and the sub-reinforcement member 62 is preferably 5 mm or more and 35 mm or less, for example, 15 mm.

[0039] Referring to Figures 1 and 3, the body parts of the wearer 9 that correspond to the first reinforcing member 6 and the second reinforcing member 7 when the sports bra 1 is worn will be described.

[0040] As shown in Figure 1, the main reinforcing member 61 is positioned to correspond to the lower outer part of the wearer's chest 9. The main reinforcing member 61 extends upward from the lower part of the wearer's chest 9, sloping outward in the width direction, and terminates at a position corresponding to the wearer's front armpit 91, where it is fixed to the main body 2. More specifically, when worn, the inner end 61e of the main reinforcing member 61 is located near the lowest point 92a of the bust line 92, and the outer end 61f is located near the lower outer part of the bust line 92 in the width direction. The vicinity of the lowest point 92a includes a range of 5 mm to 50 mm in the width direction centered on the lowest point 92a.

[0041] Generally, the bustline 92 refers to the lower boundary line of the bust of the wearer 9. In this specification, the bustline 92 refers to the position of the sports bra 1 corresponding to the lower boundary line of the bust. The lowest point 92a of the bustline 92 is located on the underbust line UL. The bustline 92 is shaped to suit various wearers depending on the size. For example, the bustline 92 may be defined by a specific mannequin (a mannequin manufactured by Nanairo Co., Ltd.: WD-20A (women's)).

[0042] As shown in Figure 3, the upper end portion 61i (main upper edge 61c) of the main reinforcing member 61 is positioned at a location corresponding to the front axillary point 91. The location corresponding to the front axillary point 91 includes a range of 30 mm or less extending inward in the width direction from the front axillary point 91. For example, the position of the upper end portion 61i of the main reinforcing member 61 may be set such that the front axillary point 91 is located within the region enclosed by the imaginary line 61g, which is an extension of the main hypotenuse 61b, the imaginary line 61h, which is an extension of the main vertical edge 61d, and the main upper edge 61c.

[0043] The main hypotenuse 61b is positioned inward from the outer portion of the wearer's bust line in the width direction. Specifically, it is positioned in a location that includes the outward diagonal downward point 9f relative to the wearer's bust top 9c. As shown in Figure 13, the outward diagonal downward point 9f is located between the lower point 9b and the outward point 9e, and is 40 mm away from the top 9c, which is located at the bust top (nipple), with the upper point 9a, lower point 9b, inner point 9d, and outer point 9e set at positions 40 mm apart in the vertical and horizontal directions, respectively. The position of the main hypotenuse 61b including the outward diagonal downward point 9f may be a range with a width of 30 mm centered on a straight line that passes through the outward diagonal downward point 9f and is parallel to the main hypotenuse 61b.

[0044] As shown in Figures 1 and 3, the sub-reinforcement member 62 is positioned to be in contact with at least the outer portion of the barges line 92 in the width direction. The upper end 62f of the sub-vertical side 62c (the intersection point of the sub-hypotenuse 62b and the sub-vertical side 62c) is preferably positioned on a horizontal line passing through the outward diagonal downward point 9f.

[0045] As shown in Figures 1 and 3, the second reinforcing member 7 is positioned above the anterior axillary point 91 of the wearer 9, passing near the anterior axillary point 91, and extending from outside the sternum to the underarm area at a position midway along the width of the clavicle, above the anterior axillary point 91 and medial in the width direction. The second reinforcing member 7 is provided at a position corresponding to the upper outer part of the wearer 9's chest. The vicinity of the anterior axillary point 91 may be a range with a width of 30 mm centered on a straight line passing through the anterior axillary point 91 and along the direction in which the second reinforcing member 7 extends.

[0046] The sports bra 1 according to this embodiment provides the following effects.

[0047] The sports bra 1 comprises a main body 2 that covers the wearer's 9 chest, connecting parts 3 that pass through the back of the wearer's 9 and connect both sides of the main body 2, and a first reinforcing member 6 that extends upward from the lower part of the wearer's 9 chest, sloping outward in the width direction, and terminating at a position corresponding to the wearer's 9 front armpit 91, and is fixed to the main body 2. The elongation of the first reinforcing portion b1 on the main body 2 where the first reinforcing member 6 is located is smaller than the elongation of the front upper portion a located on the upper side of the wearer's 9 chest on the main body 2.

[0048] With this configuration, the first reinforcing member 6 can suppress downward and / or outward movement of the chest, and because the elongation of the first reinforcing member 6 is less than the elongation of the front upper portion a located on the upper side of the chest, the upper side of the chest is less likely to be compressed. This suppresses chest movement during exercise while also suppressing excessive compression around the chest, which can cause discomfort such as shortness of breath.

[0049] Generally, it is known that chest movement during exercise such as running is greater in the outer and lower parts of the chest. More specifically, the upward swing from the bottom to the side (outside) is particularly large, and this upward swing is known to be a reaction to the downward impact caused by the downward swing. In other words, rather than suppressing the upward swing, suppressing the downward swing impact will alleviate chest movement, so by placing the first reinforcing member 6 in the lower outer part of the chest, the downward swing impact of the chest can be suppressed.

[0050] The first reinforcing member 6 is positioned to include an outward diagonal downward point 9f located outside and below the wearer's bust top 9c in the width direction.

[0051] According to this configuration, by positioning the first reinforcing member 6 at the outward diagonal downward point 9f, the movement of the outer lower part of the chest, which tends to enlarge during exercise, can be suppressed, thereby mitigating chest shaking and suppressing the impact of chest downward movement.

[0052] The outward diagonal downward point 9f is located on a circle with a radius of 40 mm centered on the bust top 9c, between the outer point 9e, which is 40 mm outward in the width direction from the bust top 9c, and the lower point 9b, which is 40 mm downward from the bust top 9c.

[0053] With this configuration, by positioning the first reinforcing member 6 at a more precise location on the outward diagonal downward point 9f where chest movement is greatest, chest shaking can be suppressed more reliably.

[0054] The first reinforcing member 6 is connected to a second reinforcing member 7 which is positioned under the armpit of the wearer 9 and fixed to the main body 2. The elongation of the second reinforcing portion b3 on the main body 2 where the second reinforcing member 7 is positioned is less than the elongation of the front upper portion a.

[0055] With this configuration, the first reinforcing member 6 can suppress downward and / or outward movement of the chest, and the second reinforcing member 7 can suppress upward swinging of the chest from below towards the side.

[0056] The ratio of the area S1 of the first reinforcing member 6 to the area S of the main body 2 is 6.9% or more and 29% or less.

[0057] With this configuration, the ratio of the area S1 of the first reinforcing member 6 is appropriately set, so that the downward and / or outward movement of the chest can be suppressed by the first reinforcing member 6. Setting it to 6.9% or more suppresses chest movement, and setting it to 29% or less suppresses excessive chest compression. The setting of the upper and lower limits of the area of ​​the first reinforcing member 6 will be explained in detail in the embodiment.

[0058] The stress in the first reinforced section b1 when it is stretched by 30% is between 15N and 51N.

[0059] According to this configuration, the stress of the first reinforcing portion b1 when it is stretched by 30% is appropriately set, so that the first reinforcing member 6 can suppress downward and / or outward movement of the chest. By setting the stress of the first reinforcing portion b1 when it is stretched by 30% to 15N or more, an excessive increase in the rigidity of the first reinforcing portion b1 is suppressed, and discomfort such as pressure on the wearer caused by the placement of the first reinforcing member 6 can be suppressed. By setting the stress of the first reinforcing portion b1 when it is stretched by 30% to 51N or less, chest movement is suppressed. The setting of the upper and lower limits of the stress of the first reinforcing portion b1 when it is stretched by 30% will be explained in detail in the embodiment.

[0060] The first reinforcing member 6 may have a roughly triangular main reinforcing member 61 that decreases in width from the lower part of the chest toward the anterior armpit 91, and a sub-reinforcing member 62 that overlaps with at least a part of the main reinforcing member 61.

[0061] With this configuration, the elongation of the main body 2 where the first reinforcing member 6 is not placed, the main reinforcing member 61, and the overlapping first three-layer reinforcing portion b2 of the main reinforcing member 61 and the sub-reinforcing member 62 can be gradually changed. Compared to the case where the first reinforcing member 6 is placed at the elongation of the first three-layer reinforcing portion b2 without an overlapping portion, abrupt changes in elongation can be suppressed, thus reducing discomfort in the part of the first reinforcing member 6 that comes into contact with the wearer 9.

[0062] In the deployed state where the main body 2 is unfolded, the inclination angle α of the first reinforcing member 6 with respect to the direction in which the lower part (lower edge 21e) of the main body 2 extends is 30 degrees or more and 60 degrees or less.

[0063] With this configuration, the inclination angle α of the first reinforcing member 6 is appropriately set, so that chest movement can be suppressed. If the inclination angle α is less than 30 degrees, the first reinforcing member 6 tends to separate from the side of the wearer's chest, making it difficult to suppress chest movement. If the inclination angle α exceeds 60 degrees, the amount of overlap between the first reinforcing member 6 and the side of the wearer's chest tends to increase, making it difficult to suppress the first reinforcing member 6 from digging into the chest.

[0064] The first reinforcing member 6 is roughly triangular in shape, with its width decreasing from the lower part of the chest toward the front armpit 91. It has a main hypotenuse (first side) 61b located on the inside in the width direction and a main vertical side (second side) 61d located on the outside. The first reinforcing member 6 is positioned so that the main hypotenuse 61b follows the side of the wearer's chest.

[0065] With this configuration, the main hypotenuse 61b can be easily brought into contact with the side of the wearer's chest, thereby suppressing chest movement.

[0066] The main body 2 has an outer fabric 21 located on the front side and a lining 22 located on the back side of the outer fabric 21, and the first reinforcing member 6 is positioned between the outer fabric 21 and the lining 22.

[0067] With this configuration, direct contact between the first reinforcing member 6 and the wearer 9 is prevented, thus suppressing any discomfort to the wearer 9 caused by the presence of the first reinforcing member 6. [Examples]

[0068] Measurement tests of breast movement during wear and sensory evaluation tests were conducted on the sports bras of Examples 1-6 and Comparative Examples 1-5. The results of these measurement and sensory evaluation tests are shown in Tables 1 and 2. Tables 1 and 2 also show the sample numbers used in each test and their characteristics. Figures 5-13 show exploded views of the main body of the sports bras of Examples 1-6 and Comparative Examples 1-5.

[0069] Comparative Example 1 is an athletic bra 101 shown in Figure 5, in which the outer fabric 21 of the main body 102 is made of a first stretchable fabric and does not have any reinforcing members. Comparative Example 2 is an athletic bra 201 shown in Figure 6, in which the main body 202 is made of a first reinforcing member 6 (main reinforcing member 61 and sub-reinforcing member 62) and a neck reinforcing member 8 attached to the neckline (neck area 21b) via hot melt adhesive, with a second stretchable fabric used for each reinforcing member and a first stretchable fabric used for the outer fabric 21. Comparative Example 3 is an athletic bra 301 shown in Figure 7, in which the main body 302 is made of a first reinforcing member 6 (main reinforcing member 61 and sub-reinforcing member 62), a second reinforcing member 7, and a neck reinforcing member 8, with a second stretchable fabric used for each reinforcing member and a first stretchable fabric used for the outer fabric. Comparative Example 4 is an athletic bra 401 shown in Figure 8, which includes a first reinforcing member 406 (main reinforcing member 461 and sub-reinforcing member 462) with a larger area than the first reinforcing member 6 of Example 1. The first reinforcing member 406 is made of a second elastic fabric, and the outer fabric 21 is made of a first elastic fabric. The first reinforcing member 406 of Comparative Example 4 extends to the side seam and is positioned to prevent the breasts from spilling out to the sides. Comparative Example 5 is an athletic bra that includes a first reinforcing member (main reinforcing member and sub-reinforcing member). Both the main reinforcing member and the sub-reinforcing member use a third elastic fabric with a higher stretchability than the first elastic fabric for the outer fabric and the first reinforcing member. The hot melt of the first reinforcing member uses a hot melt with lower rigidity compared to the other comparative examples and examples. Comparative Example 6 is an athletic bra 501 shown in Figure 9, in which the main body portion 502 is equipped with a main reinforcing member 61, the outer fabric 21 is made of a first stretchable fabric, the main reinforcing member 61 is sewn at the upper and lower ends, and the area between the upper and lower ends is not fixed and is in a non-adhesive state. Comparative Example 6 does not have a sub-reinforcing member.

[0070] Example 1 is an athletic bra 601 shown in Figure 10, comprising a first reinforcing member (main reinforcing member and sub-reinforcing member), the first reinforcing member being made of a second stretchable fabric, and the outer fabric being made of a first stretchable fabric. Example 2 is an athletic bra 1 shown in Figure 4, comprising a first reinforcing member (main reinforcing member and sub-reinforcing member) and a second reinforcing member, each reinforcing member being made of a second stretchable fabric, and the outer fabric being made of a first stretchable fabric. Example 3 is an athletic bra 701 shown in Figure 11, comprising a main reinforcing member 61 and a sub-reinforcing member 62 with a smaller area than the main reinforcing member 6 of Example 1, the first reinforcing member 706 being made of a second stretchable fabric, and the outer fabric 21 being made of a first stretchable fabric. Example 4 is an athletic bra 801 shown in Figure 12, which includes a main reinforcing member 861 having a smaller area than the main reinforcing member 761 of Example 4, and does not include a sub-reinforcing member. The main reinforcing member 861 is made of a second stretchable fabric, and the outer fabric 21 is made of a first stretchable fabric. Example 5 has the same configuration as Example 1, but the material of the first reinforcing member is different. The first reinforcing member (main reinforcing member and sub-reinforcing member) and the outer fabric of Example 5 are made of a material that exhibits a stress 30% lower when stretched than the first reinforcing member of Example 1.

[0071] Referring to Figure 13, the method for measuring breast movement during wear will be described. As shown in Figure 13, the amount of breast movement (vertical, horizontal, and forward sway) was measured by comparing the distance between six points on the chest (upper 9a, lower 9b, top 9c, inner 9d, outer 9e, and outer diagonal lower 9f) in a standing position and a fixed point Z at the neck, with the distance of the fluctuation of the six points on the chest relative to the fixed point during running on a treadmill. A motion capture camera (VICON NEXUS) was used to measure each point. The six points on the chest were set as follows: top point 9a, lower point 9b, inner point 9d, and outer point 9e were set at positions 40 mm apart in the vertical and horizontal directions, respectively, with top point 9c located at the bust top (nipple), and outer diagonal lower point 9f was set between bottom point 9b and outer point 9e and 40 mm apart from top point 9c. The average value of the measurement results for each point during one or two runs for each of two subjects was used. The amount of suppression of shaking at each point was calculated by determining the amount of suppression of vertical shaking, horizontal shaking, and forward shaking at 9f diagonally outward compared to Comparative Example 1. Since the amount of bust movement during running tended to be largest at the 9f diagonally outward point, the amount of bust movement at the 9f diagonally outward point was adopted. Therefore, the vertical shaking, horizontal shaking, and forward shaking listed in Tables 1 and 2 are the amounts of movement at 9f diagonally outward. From these results, the position of the main hypotenuse 61b of the first reinforcing member 6 (main reinforcing member 61) in Comparative Examples 2-6 and Examples 1-5 is set with the aim of suppressing the movement of the breasts at the 9f diagonally outward point. In other words, the main hypotenuse 61b of the first reinforcing member 6 is positioned to include the 9f diagonally outward point. More specifically, the main hypotenuse 61b may be within a range of 30 mm in width, centered on a straight line that passes through the 9f diagonally outward point and is parallel to the main hypotenuse 61b.

[0072] In the sensory evaluation, subjects wore Comparative Examples 1-6 and Examples 1-5, and their breathability, chest pain, and chest stability were evaluated while they performed running movements. Specifically, eight subjects (A-H) wore each exercise bra and performed running movements. Using the breathability, chest pain, chest stability, and comfort evaluations of Comparative Example 1 as a baseline, the improvement or deterioration of each exercise bra (Comparative Examples 2-6, Examples 1-5) compared to Comparative Example 1 was evaluated (bad: -1, bad: -2, very bad: -3, good: +1, good: +2, very good: +3). Tables 1 and 2 show the total scores for each item for the eight subjects.

[0073] [Table 1]

[0074] [Table 2]

[0075] As shown in Tables 1 and 2, compared to Comparative Example 1, Comparative Examples 2-6 and Examples 1-5, which are equipped with reinforcing members, show suppressed average vertical, horizontal, and forward sway. As shown in Examples 1-5, it was found that even in sports bras equipped only with the first reinforcing member, the amount of breast movement can be suppressed by more than 25%. In other words, as in Comparative Examples 2-6 and Examples 1-5, by providing the first reinforcing member 9f diagonally downwards outwards, the sway of the entire breast is suppressed compared to Comparative Example 1. In Comparative Examples 5 and 6, although they are equipped with the first reinforcing member, the stress at 30% elongation is small, resulting in poor suppression of breast movement. Furthermore, Comparative Example 5 received a result of poor stability in sensory evaluation. More specifically, because it does not have the first reinforcing member, in Example 1, when the breast moves to the side, there is an escape route to the side, whereas in Comparative Example 5, when the breast moves to the side, it comes into contact with the first reinforcing member, which has low rigidity, resulting in a feeling of poor stability.

[0076] Based on the shaking results of Examples 1 and 2, it can be said that by adding a second reinforcing member in addition to the first reinforcing member, the shaking suppression is further improved, as well as ease of breathing, chest pain, and chest stability.

[0077] Furthermore, in Comparative Example 3, which includes a neck-area reinforcing member and a second reinforcing member in addition to the first reinforcing member, and in Comparative Example 4, where the area of ​​the first reinforcing member is maximized, the ease of breathing deteriorated. In other words, although the amount of bust movement can be suppressed, from the viewpoint of ease of breathing, arranging the first, second, and neck-area reinforcing members as in Comparative Example 3, or setting the area and / or elongation of the first reinforcing member excessively as in Comparative Example 4, yielded undesirable results. On the other hand, in Comparative Example 4, some subjects experienced difficulty breathing, while the remaining subjects experienced improvement. Therefore, it can be estimated that if the values ​​are even slightly lower than those in Comparative Example 4, which does not satisfy the requirement for ease of breathing, the ease of breathing will be satisfied. Thus, it is preferable to set the ratio of the area of ​​the main reinforcing member to the area of ​​the main body 2 and the upper limit of the stress of the first reinforcing part at 30% elongation to 29% or less and 51N or less, respectively, which are lower than those in Comparative Example 4.

[0078] From the results of Comparative Example 4 and Example 4, it was found that when the ratio of the area of ​​the main reinforcing member to the area of ​​the main body 2 is 6.9% or more and 29% or less, it is possible to suppress the amount of breast movement while maintaining or improving ease of breathing. Therefore, it is preferable to set the area S of the main reinforcing member to the area of ​​the main body 2 to 6.9% or more and 29% or less. More preferably, as shown in the results of Table 2, it is preferable to set the ratio of the area of ​​the main reinforcing member to the area of ​​the main body 2 to 12.4% or less.

[0079] From the results of Comparative Example 4 and Example 4, it was found that when the stress of the first reinforced portion at 30% elongation is 15N or more and 51N or less, it is possible to suppress the amount of bust movement while maintaining or improving breathability. Therefore, it is preferable to set the stress of the first reinforced portion at 30% elongation to 15N or more and 51N or less. More preferably, as shown in the results of Table 2, it is preferable to set the stress of the first reinforced portion at 30% elongation to 31.7N or less.

[0080] In this embodiment, a configuration in which the sports bra 1 includes a first reinforcing member 6 and a second reinforcing member 7 has been described, but the sports bra 1 may also include only the first reinforcing member 6, as shown in Figure 10.

[0081] In this embodiment, a configuration in which the first reinforcing member 6 comprises a main reinforcing member 61 and a sub-reinforcing member 62 has been described, but the sports bra 1 may also consist of only the main reinforcing member 61, as shown in Figure 12.

[0082] In this embodiment, a configuration in which the main reinforcing member 61 is approximately triangular has been described, but the main reinforcing member 61 may be a strip-shaped member having a predetermined width, as shown in Figure 12.

[0083] In this embodiment, an example was described in which the first reinforcing member 6 and the second reinforcing member 7 are made of a second stretchable fabric that is harder than the outer fabric 21. However, the first reinforcing member 6 and the second reinforcing member 7 may be made of a soft fabric similar to the outer fabric 21.
