Description

[Technical field]

[0001] The present invention relates to a posture corrector. [Background technology]

[0002] Patent Document 1 discloses a conventional posture corrector. This posture corrector comprises a backrest, left and right belts, and left and right shoulder straps. The backrest is provided in the center left and right. The backrest is formed by overlapping two sheets, a front material and a back material. The backrest of this posture corrector is worn in contact with the wearer's back. The left belt extends leftward with its right end continuing from the lower left end of the backrest. The right belt extends rightward with its left end continuing from the lower right end of the backrest. The left and right belts of this posture holder are worn in contact with the wearer's torso.

[0003] The left shoulder band portion has one end fixed to the portion connecting the backrest portion and the right belt portion, and the other end detachably connected to the left belt portion. The left shoulder band portion forms a loop for passing over the wearer's left shoulder. The right shoulder band portion has one end fixed to the portion connecting the backrest portion and the left belt portion, and the other end detachably connected to the right belt portion. The right shoulder band portion forms a loop for passing over the wearer's right shoulder. The left and right shoulder band portions pass between the front and back portions of the backrest portion, and cross each other within the backrest portion.

[0004] This posture corrector can be worn as follows. First, the wearer passes his / her left shoulder through the loop formed by the left shoulder band portion, and passes his / her right shoulder through the loop formed by the right shoulder band portion. Next, the wearer grasps and pulls the other end of the left shoulder band portion with his / her left hand, connects the other end of the left shoulder band portion to the left belt portion, and grasps and pulls the other end of the right shoulder band portion with his / her right hand, connects the other end of the right shoulder band portion to the right belt portion. In this way, the wearer can wear the posture corrector. The purpose of this posture corrector is that the left and right shoulder band portions apply tension that corrects the wearer's slouching posture. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] JP 2010-104707 A Summary of the Invention [Problem to be solved by the invention]

[0006] The left and right shoulder bands of the posture corrector of Patent Document 1, when worn, press the wearer's shoulders from above to below, so that the friction of the left and right shoulder bands in contact with the left and right shoulders of the wearer is large. Therefore, when the wearer pulls the other end of the left and right shoulder bands, the part of the left and right shoulder bands located on the chest side of the wearer's shoulders is pulled stronger than the part of the left and right shoulder bands located on the back side of the wearer's shoulders. Therefore, when worn, the force of pushing the wearer's thoracic vertebrae forward from the back side is weak, and the force of opening the wearer's shoulder blades outward is weak, so that the effect of the wearer's correcting posture with the chest out may not be obtained. In addition, since the left hand pulls the left shoulder band that applies force to the left shoulder blade and the right hand pulls the right shoulder band that applies force to the right shoulder blade, the movement of the left hand pulling the left shoulder band may interfere with the movement of opening the left shoulder blade outward, and the movement of the right hand pulling the right shoulder band may interfere with the movement of opening the right shoulder blade outward.

[0007] The present invention has been made in consideration of the above-mentioned conventional circumstances, and has as its object to provide a posture corrector that enables the wearer to easily adopt a correct posture with the chest out. [Means for solving the problem]

[0008] This posture corrector comprises a left belt portion extending leftward from the left-right center, a right belt portion extending rightward from the left-right center, a left shoulder band portion having one end fixed to the left belt portion and the other end removably connected to the right belt portion, and having a portion extending from the wearer's left shoulder toward the right belt portion on the back of the wearer when worn, forming a loop for passing over the wearer's left shoulder, and a right shoulder band portion having one end fixed to the right belt portion and the other end removably connected to the left belt portion, and having a portion extending from the wearer's right shoulder toward the left belt portion on the back of the wearer when worn, forming a loop for passing over the wearer's right shoulder.

[0009] This posture correction tool is worn as described below. First, the wearer passes his / her left shoulder through the loop formed by the left shoulder band portion, and passes his / her right shoulder through the loop formed by the right shoulder band portion. Next, the wearer connects the left and right belt portions and wraps them around the torso. At this time, the torso around which the left and right belt portions are wrapped is any part from the lower part of the chest to the waist. Next, the wearer pinches the other end of the left shoulder band portion with his / her right hand, and while pulling, connects the other end of the left shoulder band portion to the right belt portion. Also, the wearer pinches the other end of the right shoulder band portion with his / her left hand, and while pulling, connects the other end of the right shoulder band portion to the left belt portion. At this time, the left and right shoulder band portions press the shoulders of the wearer from above to below, so that the friction of the parts that touch the left and right shoulders of the wearer is large. Therefore, when the wearer pulls the other ends of the left and right shoulder band portions of this posture correction tool, the parts of the left and right shoulder band portions that are located on the back side of the wearer's shoulders are pulled stronger than the parts that are located on the chest side of the wearer's shoulders. As a result, this posture corrector allows the wearer to maintain a correct posture with the chest out, as the left and right shoulder band parts push the wearer's thoracic vertebrae forward from the back while pushing the left and right shoulder blades from front to back, opening the wearer's shoulder blades outward.In addition, this posture corrector uses the right hand to pull the left shoulder band part, which transmits force to open the left shoulder blade outward, and the left hand to pull the right shoulder band part, which transmits force to open the right shoulder blade outward, so there is no risk that the movement of the hands pulling the left and right shoulder band parts will interfere with the movement of opening the left and right shoulder blades.

[0010] Therefore, the posture corrector of the present invention makes it easier for the wearer to adopt a correct posture with their chest out. [Brief description of the drawings]

[Figure 7] 1 is a diagram showing a wearer wearing the posture corrector of Example 1 as viewed from the back. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0012] A preferred embodiment of the present invention will now be described. In the posture corrector of the present invention, when worn, the left shoulder band part and the right shoulder band part may cross on the back side of the wearer. In this case, the posture corrector can appropriately push the thoracic vertebrae forward by the crossing part of the left shoulder band part and the right shoulder band part on the back side of the wearer. Therefore, the posture corrector makes it easy for the wearer to maintain a correct posture.

[0013] The posture corrector of the present invention may have a back support part provided in the left-right center, the left end of which is connected to the right end of the left belt part, and the right end of which is connected to the left end of the right belt part, and the back support part is attached to the back of the wearer. In this case, the posture corrector can appropriately push the thoracic vertebrae forward by the back support part. Therefore, the posture corrector makes it easy for the wearer to maintain a correct posture.

[0014] The back support of the posture corrector of the present invention may have a first guide portion through which the left shoulder band portion is inserted so as to be freely movable in the longitudinal direction, and a second guide portion through which the right shoulder band portion is inserted so as to be freely movable in the longitudinal direction. In this case, the posture corrector can position the left and right shoulder band portions in appropriate positions by the first guide portion and the second guide portion, and can pull the left and right shoulder band portions in appropriate directions when wearing the posture corrector. Therefore, the posture corrector can be worn appropriately, and the wearer is likely to have a correct posture.

[0015] The first and second guide parts of the posture corrector of the present invention may be provided below the intersection of the left and right shoulder band parts. In this case, the posture corrector is easily guided to the left and right belt parts by arranging the first and second guide parts below the intersection of the left and right shoulder band parts and close to the left and right belt parts. Therefore, the left and right shoulder band parts can be pulled in the appropriate direction when wearing the posture corrector, making it easy to wear.

[0016] The first and second guide parts of the posture corrector of the present invention can be inserted diagonally outward to the left and right with the left and right shoulder band parts facing downward. In this case, the first and second guide parts of the posture corrector direct the extension direction of the left and right shoulder band parts toward the left and right belt parts. Therefore, when putting on the posture corrector, the left and right shoulder band parts can be pulled in the appropriate direction, making it easy to put on.

[0017] The left and right shoulder band parts of the posture corrector of the present invention may have a portion that passes through either the first guide part or the second guide part that is more slippery than the other portions. In this case, the left and right shoulder band parts of the posture corrector can move smoothly in the longitudinal direction at the portion that passes through the first guide part and the second guide part when the posture corrector is worn. Therefore, the left and right shoulder band parts are prevented from twisting at the first guide part and the second guide part when the posture corrector is worn, and the posture corrector can be easily worn.

[0018] The left and right belt parts of the posture corrector of the present invention are stretchable in the longitudinal direction, and an elastic force can act in the contracting direction. In this case, the left and right belt parts of the posture corrector can be fitted appropriately to the torso by the elastic force of the left and right belt parts.

[0019] The left and right shoulder band parts of the posture corrector of the present invention are stretchable in the longitudinal direction, and an elastic force can act in the direction of contraction. In this case, the left and right shoulder band parts of this posture corrector can be made to fit the wearer appropriately by the elastic force of the left and right shoulder band parts. In addition, this posture corrector can push the thoracic vertebrae forward by the strong elastic force, since the parts of the left and right shoulder bands located on the back side of the wearer's shoulders are pulled and stretched more strongly than the parts located on the chest side of the wearer's shoulders.

[0020] <Example 1> Next, a first embodiment of the posture corrector 1 of the present invention will be described with reference to the drawings. In the following description, the backrest 10, the left and right belts 40, 50, and the left and right shoulder straps 60, 70 are referred to as the back side and the opposite side as the front side, respectively, when the posture corrector 1 is worn. In the following description, the vertical direction is the vertical direction when the posture corrector 1 is worn. The left and right direction is the left and right direction when viewed from the front side (hereinafter referred to as "front view") with the backrest 10 and the left and right belts 40, 50 spread out with the upper part of the posture corrector 1 facing up. In Figs. 1 and 2, the upward direction is the positive direction of the X-axis, the downward direction is the negative direction of the X-axis, the leftward direction is the positive direction of the Y-axis, and the rightward direction is the negative direction of the Y-axis.

[0021] As shown in Figs. 1 to 3, the posture corrector 1 of the first embodiment includes a back support portion 10, left and right belt portions 40, 50, and left and right shoulder band portions 60, 70. The back support portion 10 is provided in the left and right central portion. The back support portion 10 is formed of a mesh-like synthetic resin sheet. The back support portion 10 is flexible and hardly stretches.

[0022] The backrest portion 10 has a substantially hexagonal shape that is line-symmetrical about a left-right center line when viewed from the surface as shown in Fig. 1. As shown in Figs. 1 to 3, the backrest portion 10 is surrounded by an upper edge portion 11, upper left and right edges 12, 13, lower left and right edges 14, 15, and a lower edge portion 16. The upper edge portion 11 of the backrest portion 10 forms one side of the substantially hexagonal shape. The upper edge portion 11 of the backrest portion 10 extends in the left-right direction while bulging upward and curving.

[0023] Each of the upper left and right edges 12, 13 of the backrest 10 forms two sides of a substantially hexagonal shape. The upper ends of each of the upper left and right edges 12, 13 of the backrest 10 are continuous with the left and right ends of the upper edge 11, respectively. Each of the upper left and right edges 12, 13 of the backrest 10 extends diagonally downward toward the outside in the left-right direction. Each of the upper left and right edges 12, 13 of the backrest 10 is curved, recessed diagonally downward toward the inside in the left-right direction.

[0024] Each of the lower left and right edges 14, 15 of the backrest 10 forms two sides of a substantially hexagonal shape. The upper ends of each of the lower left and right edges 14, 15 of the backrest 10 are continuous with the lower ends of the upper left and right edges 12, 13. Each of the lower left and right edges 14, 15 of the backrest 10 extends in a straight line diagonally downward toward the inside in the left-right direction. The lower edge 16 of the backrest 10 forms one side of the substantially hexagonal shape. The left and right ends of the lower edge 16 of the backrest 10 are continuous with the lower ends of each of the lower left and right edges 14, 15. The lower edge 16 of the backrest 10 extends in the left-right direction. The lower edge 16 of the backrest 10 is curved and slightly concave upward.

[0025] 1, the backrest portion 10 has a first guide portion 20 and a second guide portion 30. The first guide portion 20 and the second guide portion 30 are formed by a first surface member 21 and a second surface member 31 attached to the front surface of the backrest portion 10 (hereinafter referred to as the "surface of the backrest portion 10"). The first surface member 21 and the second surface member 31 are formed by the same mesh-like synthetic resin sheet as the backrest portion 10.

[0026] The first surface member 21 and the second surface member 31 are rectangular and surrounded by outer edges 21A, 31A, inner edges 21B, 31B, upper edges 21C, 31C, and lower edges 21D, 31D. The outer edges 21A, 31A of the first surface member 21 and the second surface member 31 form one side of the rectangular shape. The outer edge 21A of the first surface member 21 curves to overlap the lower part of the upper right edge 13 of the backrest 10 and extends diagonally downward toward the right. The outer edge 21A of the first surface member 21 is bonded along the lower part of the upper right edge 13 of the backrest 10. The outer edge 31A of the second surface member 31 curves to overlap the lower part of the upper left edge 12 of the backrest 10 and extends diagonally downward toward the left. The outer edge 31A of the second surface member 31 is adhered along the lower part of the upper left edge 12 of the backrest portion 10.

[0027] The inner edges 21B, 31B of the first surface member 21 and the second surface member 31 form one side of a quadrangle. The inner edge 21B of the first surface member 21 is generally parallel to the outer edge 21A, and extends obliquely downward toward the right while curving to be generally parallel to the lower part of the upper right edge 13 of the backrest 10. The inner edge 31B of the second surface member 31 is generally parallel to the outer edge 31A, and extends obliquely downward toward the left while curving to be generally parallel to the lower part of the upper left edge 12 of the backrest 10. The inner edges 21B, 31B of the first surface member 21 and the second surface member 31 are bonded to the surface of the backrest 10.

[0028] The upper edges 21C, 31C of the first surface member 21 and the second surface member 31 form one side of a rectangle. The left and right ends of the upper edge 21C of the first surface member 21 are continuous with the upper end of the outer edge 21A and the upper end of the inner edge 21B. The upper edge 21C of the first surface member 21 extends in a straight line slightly diagonally downward toward the left. The left and right ends of the upper edge 31C of the second surface member 31 are continuous with the upper end of the outer edge 31A and the upper end of the inner edge 31B. The upper edge 31C of the second surface member 31 extends in a straight line slightly diagonally downward toward the right.

[0029] The lower edges 21D, 31D of the first surface member 21 and the second surface member 31 form one side of a rectangle. The left and right ends of the lower edge 21D of the first surface member 21 are continuous with the lower end of the outer edge 21A and the lower end of the inner edge 21B. The lower edge 21D of the first surface member 21 extends diagonally downward in a straight line toward the left so as to overlap the upper part of the lower right edge 15 of the backrest 10. The left and right ends of the lower edge 31D of the second surface member 31 are continuous with the lower end of the outer edge 31A and the lower end of the inner edge 31B. The lower edge 31D of the second surface member 31 extends diagonally downward in a straight line toward the right so as to overlap the upper part of the lower left edge 14 of the backrest 10.

[0030] The first surface member 21 and the second surface member 31 attached to the backrest 10 are symmetrical with respect to the left-right center line in the surface view. Only the outer edges 21A, 31A and the inner edges 21B, 31B of the first surface member 21 and the second surface member 31 are bonded to the surface of the backrest 10. Therefore, the left shoulder band 60 described later can be inserted between the first surface member 21 from the upper edge 21C to the lower edge 21D of the first surface member 21 and the backrest 10 in a freely movable manner in the longitudinal direction. In other words, the first surface member 21 attached to the backrest 10 forms a first guide portion 20 through which the left shoulder band 60 can be inserted in a freely movable manner in the longitudinal direction. Similarly, the right shoulder band 70 described later can be inserted between the second surface member 31 from the upper edge 31C to the lower edge 31D of the second surface member 31 and the backrest 10 in a freely movable manner in the longitudinal direction. In other words, the second guide portion 30 through which the right shoulder strap portion 70 is inserted so as to be freely movable in the longitudinal direction is formed by the second surface member 31 attached to the backrest portion 10.

[0031] The left and right belt parts 40, 50 are belt-shaped extending in the left-right direction in surface view. The right edge part 41 of the left belt part 40 is continuous with the lower left edge part 14 of the backrest part 10 as shown in Figs. 1 to 3. The length of the right edge part 41 of the left belt part 40 is equal to the length of the lower left edge part 14 of the backrest part 10. The left belt part 40 extends leftward from the lower left edge part 14 of the backrest part 10. The left edge part 42 of the left belt part 40 bulges leftward in an arc shape. The left edge part 51 of the right belt part 50 is continuous with the lower right edge part 15 of the backrest part 10. The length of the left edge part 51 of the right belt part 50 is equal to the length of the lower right edge part 15 of the backrest part 10. The right belt part 50 extends rightward from the lower right edge part 15 of the backrest part 10. The right edge 52 of the right belt portion 50 bulges rightward in an arc shape.

[0032] The upper edges 43, 53 of the left and right belt parts 40, 50 are continuous with the upper left and right edges 12, 13 of the backrest part 10. The upper edges 43, 53 of the left and right belt parts 40, 50 are slightly curved near the backrest part 10 side so as to be continuous with the upper left and right edges 12, 13 of the backrest part 10. The lower edges 44, 54 of the left and right belt parts 40, 50 are continuous with the lower edge 16 of the backrest part 10. The width of the left and right belt parts 40, 50 in the vertical direction is slightly reduced from the backrest part 10 side toward the outside in the left and right direction. The upper edges 43, 53 and the lower edges 44, 54 of the left and right belt parts 40, 50 extend in a substantially straight line slightly diagonally downward toward the outside in the left and right direction. The left belt part 40 and the right belt part 50 located on the left and right of the backrest part 10 are symmetrical with respect to the left and right center line in the surface view shown in FIG. 1. As shown in Figs. 1 and 2, the outer periphery of the integrated back support portion 10 and the left and right belt portions 40, 50 is bordered with a tape 80 that is stretchable in the longitudinal direction.

[0033] As shown in FIG. 1, the left and right belt parts 40, 50 have a belt part main body 100 and a female hook-and-loop fastener 110. The belt part main body 100 is a band-like shape that forms the overall outer shape of each of the left and right belt parts 40, 50 when viewed from the surface as shown in FIG. 1. The belt part main body 100 is stretchable in the longitudinal direction, and an elastic force acts in the contraction direction. The belt part main body 100 is flexible and hardly stretches in the lateral direction. The female hook-and-loop fastener 110 is fixed by sewing from the longitudinal middle part of the belt part main body 100 to the entire outer surface of the left and right outer sides. The female hook-and-loop fastener 110 has a surface on which a plurality of fine loops are formed that is exposed on the outer side. The female hook-and-loop fastener 110 is flexible and hardly stretches in the lateral direction.

[0034] As shown in FIG. 2, the posture corrector 1 is provided with a non-slip portion 90 formed in a strip shape on the back surface along the boundary between the left and right belt portions 40, 50 and the backrest portion 10. The non-slip portion 90 has a plurality of resin protrusions protruding to the back side. The right belt portion 50 is fixed by sewing a male hook-and-loop fastener 150 to the back surface of the tip portion located at the rightmost side. The surface of the male hook-and-loop fastener 150 on which a plurality of fine hooks are formed is exposed to the back side. The male hook-and-loop fastener 150 is almost inelastic and flexible. When wearing the posture corrector 1, the wearer can freely attach and detach the male hook-and-loop fastener 150 provided on the right belt portion 50 to a desired position of the female hook-and-loop fastener 110 provided on the left belt portion 40, and the right belt portion 50 and the left belt portion 40 can be connected.

[0035] As shown in Figs. 1 to 3, the left and right shoulder band parts 60, 70 are belt-shaped. The left and right shoulder band parts 60, 70 have a band part main body 120 and a sliding member 130. The band part main body 120 is belt-shaped. The band part main body 120 is stretchable in the longitudinal direction, and an elastic force acts in the contraction direction. The band part main body 120 hardly stretches in the lateral direction and is flexible. The sliding member 130 is belt-shaped. The sliding member 130 has the same width as the band part main body 120 and is longer than the insertion length of the first guide part 20 and the second guide part 30. The sliding member 130 hardly stretches and is flexible. The sliding member 130 is sewn and fixed to the front surface of the band part main body 120 at the part where the left and right shoulder band parts 60, 70 are inserted through the first guide part 20 and the second guide part 30. The front surface of the sliding member 130 is raised. For this reason, the left and right shoulder bands at the portions where the sliding member 130 is fixed slide more easily than other portions, and can move smoothly in the longitudinal direction while inserted through the first guide portion 20 and the second guide portion 30.

[0036] One end of the left shoulder band portion 60 is closer to the backrest portion 10 than the middle portion of the left belt portion 40 in the longitudinal direction, and is sewn and fixed to the upper edge portion 43 of the left belt portion 40 to which the female hook-and-loop fastener 110 is not fixed. The left shoulder band portion 60 passes through the first guide portion 20. The left shoulder band portion 60 is connected to the backrest portion 10 by the first connecting member 61 at the one end side of the portion where the first guide portion 20 is passed through. The first connecting member 61 is belt-shaped. The first connecting member 61 is stretchable in the longitudinal direction, and an elastic force acts in the contracting direction. The first connecting member 61 is flexible and hardly stretches in the lateral direction. One end of the first connecting member 61 is sewn and fixed to the front surface of the boundary between the upper edge portion 11 and the upper left edge portion 12 of the backrest portion 10. The other end of the first connecting member 61 is sewn and fixed to the back surface of the left shoulder band portion 60. The left shoulder band part 60 forms a loop for passing over the wearer's left shoulder between one end fixed to the left belt part 40 and the part to which the first connecting member 61 is fixed. In other words, a part of the left shoulder band part 60, the upper left edge part 12 of the backrest part 10, and a part of the upper edge part 43 of the left belt part 40 form a loop for passing over the wearer's left shoulder.

[0037] As shown in Figs. 1 and 3, the other end of the left shoulder band portion 60 has a male hook-and-loop fastener 160 sewn and fixed to the back surface. The surface of the male hook-and-loop fastener 160 on which multiple fine hooks are formed is exposed on the back side. The male hook-and-loop fastener 160 hardly stretches and is flexible. When wearing the posture corrector 1, the wearer can freely attach and detach the male hook-and-loop fastener 160 provided on the other end of the left shoulder band portion 60 to a desired position on the female hook-and-loop fastener 110 provided on the right belt portion 50, thereby connecting the left shoulder band portion 60 and the right belt portion 50.

[0038] The other end of the left shoulder band portion 60 is connected to the right belt portion 50 by a second connecting member 62. The second connecting member 62 is belt-shaped. The second connecting member 62 is stretchable in the longitudinal direction, and elastic force acts in the direction of contraction. The second connecting member 62 is flexible and hardly stretches in the lateral direction. One end of the second connecting member 62 is located in the longitudinal middle of the right belt portion 50, and is sewn and fixed to the center in the vertical direction of the left end of the female hook-and-loop fastener 110. The other end of the second connecting member 62 is sewn and fixed to the left end of the male hook-and-loop fastener 160 provided at the other end of the left shoulder band portion 60.

[0039] One end of the right shoulder band part 70 is closer to the backrest part 10 than the longitudinal middle part of the right belt part 50, and is sewn and fixed to the upper edge part 53 of the right belt part 50 to which the female hook-and-loop fastener 110 is not fixed. The right shoulder band part 70 passes through the second guide part 30. The right shoulder band part 70 is connected to the backrest part 10 by a third connecting member 71 at the one end side of the part where the second guide part 30 is passed through. The third connecting member 71 is made of the same material as the first connecting member 61 and has the same shape. One end of the third connecting member 71 is sewn and fixed to the front surface of the boundary between the upper edge part 11 and the upper right edge part 13 of the backrest part 10. The other end of the third connecting member 71 is sewn and fixed to the back surface of the right shoulder band part 70. The right shoulder band part 70 forms a loop for passing over the wearer's right shoulder between one end fixed to the right belt part 50 and the part to which the third connecting member 71 is fixed. In other words, a part of the right shoulder band part 70, the upper right edge part 13 of the backrest part 10, and a part of the upper edge part 53 of the right belt part 50 form a loop for passing over the wearer's right shoulder.

[0040] The other end of the right shoulder band portion 70 has a male hook-and-loop fastener 170 sewn and fixed to the back surface. The surface of the male hook-and-loop fastener 170 on which multiple fine hooks are formed is exposed on the back surface. The male hook-and-loop fastener 170 hardly stretches and is flexible. When putting on the posture corrector 1, the wearer can freely attach and detach the male hook-and-loop fastener 170 provided on the other end of the right shoulder band portion 70 to a desired position on the female hook-and-loop fastener 110 provided on the left belt portion 40, thereby connecting the right shoulder band portion 70 and the left belt portion 40.

[0041] The other end of the right shoulder band portion 70 is connected to the left belt portion 40 by a fourth connecting member 72. The fourth connecting member 72 is made of the same material and has the same shape as the second connecting member 62. One end of the fourth connecting member 72 is located at the middle part in the longitudinal direction of the left belt portion 40, and is fixed by sewing to the center in the vertical direction of the right end of the female hook-and-loop fastener 110. The other end of the fourth connecting member 72 is overlapped and sewn to the right end of the male hook-and-loop fastener 170 provided at the other end of the right shoulder band portion 70.

[0042] As shown in FIG. 7, the left shoulder band portion 60 has a portion extending from the wearer's left shoulder toward the right belt portion 50 on the back side of the wearer when worn. The right shoulder band portion 70 has a portion extending from the wearer's right shoulder toward the left belt portion 40 on the back side of the wearer when worn. The left shoulder band portion 60 and the right shoulder band portion 70 cross each other on the back side of the wearer. In detail, the left and right shoulder band portions 60, 70 cross each other from the portion where the other end of the first connecting member 61 of the left shoulder band portion 60 is fixed to the portion where it is inserted into the first guide portion 20, and from the portion where the other end of the third connecting member 71 of the right shoulder band portion 70 is fixed to the portion where it is inserted into the second guide portion 30. The first guide portion 20 and the second guide portion 30 are provided below the portion where the left shoulder band portion 60 and the right shoulder band portion 70 cross each other.

[0043] This posture corrector 1 is worn as described below. First, as shown in FIG. 4, the wearer passes his / her left shoulder through the loop formed by the left shoulder band portion 60, and passes his / her right shoulder through the loop formed by the right shoulder band portion 70. Next, the wearer grasps the right end portion of the right belt portion 50 with his / her right hand and pulls the right belt portion 50 to the left, and grasps the left end portion of the left belt portion 40 with his / her left hand and pulls the left belt portion 40 to the right, while connecting the male hook-and-loop fastener 150 provided on the right belt portion 50 to the desired position of the female hook-and-loop fastener 110 provided on the left belt portion 40, thereby connecting the right belt portion 50 and the left belt portion 40. At this time, the wearer adjusts the pulling force of the left and right belt portions 40, 50 so that the left and right belt portions 40, 50 are wrapped around the torso (any part from the lower chest to the waist) at an appropriate position in the vertical direction and with an appropriate elastic force. The back surface of the back support portion 10 is in contact with the back of the wearer when the seat belt is worn. The back surfaces of the left and right belt portions 40, 50 are in contact with the torso of the wearer when the seat belt is worn.

[0044] Next, as shown in Fig. 5, the wearer grasps the other end of the left shoulder band portion 60 with his right hand and, while pulling, fastens the male hook-and-loop fastener 160 provided at the other end of the left shoulder band portion 60 to the female hook-and-loop fastener 110 provided at the right belt portion 50 at a desired position, thereby connecting the other end of the left shoulder band portion 60 to the right belt portion 50. The wearer also grasps the other end of the right shoulder band portion 70 with his left hand and, while pulling, fastens the male hook-and-loop fastener 170 provided at the other end of the right shoulder band portion 70 to the female hook-and-loop fastener 110 provided at the left belt portion 40 at a desired position, thereby connecting the other end of the right shoulder band portion 70 to the left belt portion 40 (see Fig. 6). At this time, the wearer adjusts the pulling strength of the left and right shoulder band parts 60, 70 so that the left and right shoulder band parts 60, 70 push the wearer's thoracic vertebrae forward from the back side via the back support part 10 while the left and right shoulder band parts 60, 70 push the left and right shoulder blades from the front to the rear, opening the wearer's shoulder blades outward and assuming a correct posture with the chest out.

[0045] As described above, the posture corrector 1 of the first embodiment includes the left belt portion 40, the right belt portion 50, the left shoulder band portion 60, and the right shoulder band portion 70. The left belt portion 40 extends leftward from the backrest portion 10 provided in the left-right center portion. The right belt portion 50 extends rightward from the backrest portion 10 provided in the left-right center portion. The left shoulder band portion 60 has one end fixed to the left belt portion 40, and the other end detachably connected to the right belt portion 50. When worn, the left shoulder band portion 60 has a portion extending from the left shoulder of the wearer toward the right belt portion 50 on the back side of the wearer, forming a loop through which the left shoulder of the wearer passes. The right shoulder band portion 70 has one end fixed to the right belt portion 50, and the other end detachably connected to the left belt portion 40. When worn, the right shoulder band portion 70 has a portion that extends from the wearer's right shoulder toward the left belt portion 40 on the wearer's back, forming a loop that passes over the wearer's right shoulder.

[0046] When the left and right shoulder band parts 60, 70 of the posture corrector 1 are worn, they press the wearer's shoulders from above to below, so friction is increased at the parts that touch the left and right shoulders of the wearer. Therefore, when the wearer pulls the other end of the left and right shoulder band parts 60, 70 of the posture corrector 1, the parts of the left and right shoulder band parts 60, 70 arranged on the back side of the wearer's shoulders are pulled stronger than the parts arranged on the chest side of the wearer's shoulders. As a result, the left and right shoulder band parts 60, 70 push the wearer's thoracic vertebrae forward from the back side via the back support part 10, while the left and right shoulder band parts 60, 70 push the left and right shoulder blades from the front to the back, opening the wearer's shoulder blades outward, so that the wearer can maintain a correct posture with his or her chest out. In addition, with this posture corrector 1, the right hand pulls the left shoulder band portion 60, which transmits force to open the left shoulder blade outward, and the left hand pulls the right shoulder band portion 70, which transmits force to open the right shoulder blade outward, so there is no risk that the movement of the hands pulling the left and right shoulder band portions 60, 70 will interfere with the movement of opening the left and right shoulder blades.

[0047] Therefore, the posture corrector 1 of the first embodiment makes it easier for the wearer to maintain a correct posture with the chest out.

[0048] In the posture corrector 1 of the first embodiment, when worn, the left shoulder band part 60 and the right shoulder band part 70 cross over each other on the back side of the wearer. In this posture corrector 1, the crossing part of the left shoulder band part 60 and the right shoulder band part 70 on the back side of the wearer can appropriately push the thoracic vertebrae forward via the back support part 10. Therefore, this posture corrector 1 makes it easy for the wearer to maintain a correct posture.

[0049] The posture corrector 1 of the first embodiment is provided in the left-right center, with the right end of the left belt part 40 continuing to the left end, and the left end of the right belt part 50 continuing to the right end, and is provided with a back support part 10 that is worn by touching the back of the wearer. This posture corrector 1 can appropriately push the thoracic vertebrae forward with the back support part 10. Therefore, this posture corrector 1 makes it easy for the wearer to maintain a correct posture.

[0050] The back support portion 10 of the posture corrector 1 of the first embodiment has a first guide portion 20 through which the left shoulder band portion 60 is inserted so as to be freely movable in the longitudinal direction, and a second guide portion 30 through which the right shoulder band portion 70 is inserted so as to be freely movable in the longitudinal direction. This posture corrector 1 can position the left and right shoulder band portions 60, 70 in appropriate positions by the first guide portion 20 and the second guide portion 30, and can pull the left and right shoulder band portions 60, 70 in appropriate directions when wearing the posture corrector 1. Therefore, this posture corrector 1 can be worn appropriately, and the wearer can easily maintain a correct posture.

[0051] The first guide portion 20 and the second guide portion 30 of the posture corrector 1 of the first embodiment are provided below the intersection of the left shoulder band portion 60 and the right shoulder band portion 70. By arranging the first guide portion 20 and the second guide portion 30 in a position below the intersection of the left shoulder band portion 60 and the right shoulder band portion 70 and close to the left and right belt portions 40, it is easy to guide the ends of the left and right shoulder band portions 60, 70 to the left and right belt portions 40, 50. Therefore, when putting on the posture corrector 1, the left and right shoulder band portions 60, 70 can be pulled in an appropriate direction, making it easy to put on.

[0052] The first guide portion 20 and the second guide portion 30 of the posture corrector 1 of the first embodiment are inserted obliquely outward to the left and right through the left shoulder band portion 60 and the right shoulder band portion 70 facing downward. The first guide portion 20 and the second guide portion 30 of this posture corrector 1 direct the extension direction of the left and right shoulder band portions 60, 70 toward the left and right belt portions 40, 50. Therefore, when putting on the posture corrector 1, the left and right shoulder band portions 60, 70 can be pulled in the appropriate direction, making it easy to put on.

[0053] The left shoulder band part 60 and the right shoulder band part 70 of the posture corrector 1 of the first embodiment are more slippery than other parts because the sliding member 130 is fixed to the part that passes through either the first guide part 20 or the second guide part 30. When the left and right shoulder band parts 60, 70 of the posture corrector 1 are worn, the part that passes through the first guide part 20 and the second guide part 30 can move smoothly in the longitudinal direction. Therefore, when the posture corrector 1 is worn, the left and right shoulder band parts 60, 70 are prevented from twisting in the first guide part 20 and the second guide part 30, and the posture corrector 1 can be easily worn.

[0054] The left belt part 40 and the right belt part 50 of the posture corrector 1 of the first embodiment are stretchable in the longitudinal direction, and an elastic force acts in the contracting direction. This posture corrector 1 can appropriately fit the left and right belt parts 40, 50 to the torso by the elastic force of the left and right belt parts 40, 50.

[0055] The left shoulder band part 60 and the right shoulder band part 70 of the posture corrector 1 of the first embodiment are stretchable in the longitudinal direction, and an elastic force acts in the direction of contraction. This posture corrector 1 can make the left and right shoulder band parts 60, 70 fit the wearer appropriately by the elastic force of the left and right shoulder band parts 60, 70. Also, this posture corrector 1 can push the thoracic vertebrae forward by the strong elastic force because the parts of the left and right shoulder bands arranged on the back side of the wearer's shoulders are pulled and stretched more strongly than the parts arranged on the chest side of the wearer's shoulders.

[0056] The present invention is not limited to the first embodiment described above with reference to the drawings, and the following embodiments are also included within the technical scope of the present invention. (1) In the posture corrector of the first embodiment, the left and right shoulder strap portions cross each other, but the left and right shoulder strap portions do not have to cross each other. (2) Although the posture corrector of the first embodiment includes a back support portion, it does not necessarily have to include a back support portion. (3) The backrest of the posture corrector of the first embodiment includes a first guide portion and a second guide portion, but the backrest does not necessarily need to include the first guide portion and the second guide portion. Also, the backrest may include a guide portion that connects the left and right shoulder band portions to predetermined positions on the backrest, rather than a guide portion that allows the left and right shoulder band portions to be inserted movably in the longitudinal direction. (4) In Example 1, the first guide portion and the second guide portion are provided below the intersection of the left shoulder band portion and the right shoulder band portion, but the first guide portion and the second guide portion may be provided above the intersection of the left shoulder band portion and the right shoulder band portion. (5) In Example 1, the first guide portion and the second guide portion are inserted diagonally outward to the left and right through the left and right shoulder band portions in a downward direction, but the first guide portion and the second guide portion do not have to be inserted diagonally outward to the left and right through the left and right shoulder band portions in a downward direction. (6) In the first embodiment, the left and right shoulder strap parts are made more slippery than other parts by fixing a sliding member to the part where the first guide part and the second guide part are inserted, but the sliding member does not have to be fixed. Also, the left and right shoulder strap parts may be made slippery overall. (7) In the first embodiment, the left and right belt portions are stretchable in the longitudinal direction, and an elastic force acts in the direction of contraction. However, the left and right belt portions do not have to stretch in the longitudinal direction. (8) In the first embodiment, the left and right shoulder band portions are stretchable in the longitudinal direction and an elastic force acts in the contraction direction, but the left and right shoulder band portions do not have to stretch in the longitudinal direction. (9) In the left and right belt portions of Example 1, the male hook-and-loop fastener on the right belt portion is removably connected to the desired position of the female hook-and-loop fastener on the left belt portion. However, the left end of the left belt portion and the right end of the right belt portion may be non-detachably connected, and the left and right belt portions may be stretched and contracted in the longitudinal direction so as to fit around the torso.
