Description

The present invention relates to a posture correction device.

Patent Document 1 discloses a conventional posture corrector. This posture corrector comprises a backrest, left and right belt sections, and left and right shoulder band sections. The backrest is provided in the left and right central sections. 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 section extends leftward with its right end continuing from the lower part of the left end of the backrest. The right belt section extends rightward with its left end continuing from the lower part of the right end of the backrest. The left and right belt sections of this posture holder are worn in contact with the wearer's torso.

The left shoulder band has one end fixed to the part connecting the backrest and the right belt, and the other end removably connected to the left belt. The left shoulder band forms a loop for passing over the wearer's left shoulder. The right shoulder band has one end fixed to the part connecting the backrest and the left belt, and the other end removably connected to the right belt. The right shoulder band forms a loop for passing over the wearer's right shoulder. The left and right shoulder bands pass between the front and back of the backrest, and cross within the backrest.

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, and his/her right shoulder through the loop formed by the right shoulder band. Next, the wearer grasps and pulls the other end of the left shoulder band with his/her left hand, connects the other end of the left shoulder band to the left belt, and grasps and pulls the other end of the right shoulder band with his/her right hand, connects the other end of the right shoulder band to the right belt. In this way, the wearer can wear the posture corrector. The purpose of this posture corrector is for the left and right shoulder bands to apply tension that corrects the wearer's slouching posture.

JP 2010-104707 A

When the left and right shoulder bands of the posture corrector of Patent Document 1 are worn, they press down on the wearer's shoulders, causing high friction at the parts of the shoulder bands that come into contact with the wearer's left and right shoulders. For this reason, when the wearer pulls on the other ends of the left and right shoulder bands, the parts of the shoulder bands that are closer to the chest than the wearer's shoulders are pulled more strongly than the parts that are closer to the back than the wearer's shoulders. As a result, when worn, this posture corrector exerts a weak force on the wearer's thoracic vertebrae from the back to the front, and the force that opens the wearer's shoulder blades outward is weak, which may prevent the wearer from achieving the correct posture with their chest out. In addition, with this posture corrector, the left shoulder band that applies force to the left shoulder blade is pulled with the left hand, and the right shoulder band that applies force to the right shoulder blade is pulled with the right hand, so 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.

The present invention was made in consideration of the above-mentioned conventional circumstances, and the problem to be solved is to provide a posture corrector that helps the wearer to maintain a correct posture with their chest out.

This posture correction device is equipped with a left belt section extending leftward from the left-right center section, a right belt section extending rightward from the left-right center section, a left shoulder band section having one end fixed to the left belt section and the other end detachably connected to the right belt section, which has a portion extending from the wearer's left shoulder toward the right belt section on the back side of the wearer when worn, forming a loop for passing over the wearer's left shoulder, and a right shoulder band section having one end fixed to the right belt section and the other end detachably connected to the left belt section, which has a portion extending from the wearer's right shoulder toward the left belt section on the back side of the wearer when worn, forming a loop for passing over the wearer's right shoulder.

This posture correction device 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 holds 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 holds 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 wearer's shoulders 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 device, 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. Also, with this posture corrector, the right hand is used to pull the left shoulder band part, which transmits force to open the left shoulder blade outward, and the left hand is used 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.

Therefore, the posture correction device of the present invention makes it easier for the wearer to maintain correct posture with their chest out.

FIG. 1 is a perspective view showing a state in which the left and right shoulder band portions of the posture corrector of the first embodiment are connected to the left and right belt portions. FIG. 1 is a perspective view of a wearer wearing a posture correcting device according to a first embodiment, as viewed from the chest side. FIG. 1 is a diagram showing a wearer wearing the posture correcting device of Example 1 as viewed from the back.

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.

The posture corrector of the present invention may be provided with a back support part that is provided in the left-right center, the left end of which is continuous with the right end of the left belt part, and the right end of which is continuous with the left end of the right belt part, and is worn by touching the back of the wearer. In this case, the posture corrector can appropriately push the thoracic vertebrae forward with the back support part. Therefore, this posture corrector makes it easier for the wearer to maintain a correct posture.

The back support portion 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 properly, and the wearer is more likely to adopt a correct posture.

The first guide portion and the second guide portion of the posture corrector of the present invention can be provided below the intersection of the left shoulder band portion and the right shoulder band portion. In this case, by arranging the first guide portion and the second guide portion in a position below the intersection of the left shoulder band portion and the right shoulder band portion and close to the left and right belt portions, it is easy to guide the end sides of the left and right shoulder band portions into the left and right belt portions. Therefore, when putting on this posture corrector, the left and right shoulder band portions can be pulled in the appropriate direction, making it easy to put on.

The first and second guide parts of the posture corrector of the present invention can be inserted through the left and right shoulder band parts diagonally outwardly and 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.

The left and right shoulder band parts of the posture corrector of the present invention may be slippery at the portions that pass through either the first guide part or the second guide part compared to other portions. In this case, when the left and right shoulder band parts of the posture corrector are put on, the portions that pass through the first guide part and the second guide part can move smoothly in the longitudinal direction. Therefore, when the posture corrector is put on, the left and right shoulder band parts are prevented from twisting in the first guide part and the second guide part, making it easy to put on.

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 direction of contraction. In this case, the elastic force of the left and right belt parts of this posture corrector allows the left and right belt parts to fit properly around the torso.

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 elastic force of the left and right shoulder band parts allows this posture corrector to properly fit the left and right shoulder band parts to the wearer. Also, with this posture corrector, 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, so the strong elastic force can push the thoracic vertebrae forward.

As shown in Figures 1 to 3, the backrest 10 is surrounded by an upper edge 11, upper left and right edges 12, 13, lower left and right edges 14, 15, and a lower edge 16. The upper edge 11 of the backrest 10 forms one side of the generally hexagonal shape. The upper edge 11 of the backrest 10 curves upward and extends in the left-right direction.

The upper left and right edges 12, 13 of the backrest 10 each form two sides of a roughly hexagonal shape. The upper ends 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. The upper left and right edges 12, 13 of the backrest 10 each extend diagonally downward toward the outside in the left-right direction. The upper left and right edges 12, 13 of the backrest 10 each curve diagonally downward toward the inside in the left-right direction.

The lower left and right edges 14, 15 of the backrest 10 each form two sides of a substantially hexagon. The upper ends 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. The lower left and right edges 14, 15 of the backrest 10 each extend diagonally downward in a straight line toward the inside in the left-right direction. The lower edge 16 of the backrest 10 forms one side of the substantially hexagon. The left and right ends of the lower edge 16 of the backrest 10 are continuous with the lower ends 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.

As shown in FIG. 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 from the same mesh-like synthetic resin sheet as the backrest portion 10.

The first surface member 21 and the second surface member 31 are rectangular, 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 glued along 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 form one side of a rectangle. The inner edge 21B of the first surface member 21 is approximately parallel to the outer edge 21A, and extends diagonally downward toward the right while curving to be approximately 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 approximately parallel to the outer edge 31A, and extends diagonally downward toward the left while curving to be approximately 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.

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.

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.

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 edge 21A, 31A and the inner edge 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 freely 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 surface member 31 attached to the backrest 10 forms the second guide portion 30 through which the right shoulder strap portion 70 can be inserted in a freely movable manner in the longitudinal direction.

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

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 vertical width of the left and right belt parts 40, 50 decreases slightly 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 linearly symmetrical with the left and right center line as an axis of symmetry in the surface view shown in FIG. 1. The outer edges of the integrated backrest 10 and left and right belt sections 40, 50 are bordered with tape 80 that is stretchable in the longitudinal direction, as shown in Figures 1 and 2.

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 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 surface of the female hook-and-loop fastener 110 on which multiple fine loops are formed is exposed on the outer side. The female hook-and-loop fastener 110 is flexible and hardly stretches.

As shown in FIG. 2, the posture corrector 1 has 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 multiple resin protrusions protruding to the back side. The right belt portion 50 has a male hook-and-loop fastener 150 sewn and fixed to the back surface of the tip portion located at the rightmost side. The male hook-and-loop fastener 150 has a surface with multiple fine hooks formed exposed on the back side. The male hook-and-loop fastener 150 has little stretch and is 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 the 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.

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 pass through the first guide part 20 and the second guide part 30. The front surface of the sliding member 130 is brushed. As a result, the left and right shoulder bands where the sliding member 130 is fixed slide more easily than other parts, and can move smoothly in the longitudinal direction while inserted through the first guide part 20 and the second guide part 30.

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 portion 60 forms a loop for passing over the wearer's left shoulder between one end fixed to the left belt portion 40 and the portion to which the first connecting member 61 is fixed. In other words, a portion of the left shoulder band portion 60, the upper left edge portion 12 of the backrest portion 10, and a portion of the upper edge portion 43 of the left belt portion 40 form a loop for passing over the wearer's left shoulder.

As shown in Figs. 1 and 3, the other end of the left shoulder band 60 is fixed by sewing a male hook-and-loop fastener 160 to the back surface. The surface of the male hook-and-loop fastener 160 with multiple fine hooks is exposed on the back side. The male hook-and-loop fastener 160 is flexible and hardly stretches. 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 60 to the desired position of the female hook-and-loop fastener 110 provided on the right belt 50, thereby connecting the left shoulder band 60 and the right belt 50.

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 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 portion 70 forms a loop for passing over the wearer's right shoulder between one end fixed to the right belt portion 50 and the portion to which the third connecting member 71 is fixed. In other words, a portion of the right shoulder band portion 70, the upper right edge portion 13 of the backrest portion 10, and a portion of the upper edge portion 53 of the right belt portion 50 form a loop for passing over the wearer's right shoulder.

The other end of the right shoulder band 70 is fixed by sewing a male hook-and-loop fastener 170 to the back surface. The surface of the male hook-and-loop fastener 170 with multiple fine hooks is exposed on the back surface. The male hook-and-loop fastener 170 is flexible and hardly stretches. When wearing the posture corrector 1, the wearer can freely attach and detach the male hook-and-loop fastener 170 on the other end of the right shoulder band 70 to the desired position of the female hook-and-loop fastener 110 on the left belt portion 40, thereby connecting the right shoulder band 70 and the left belt portion 40.

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 in the middle of the length of the left belt portion 40, and is sewn and fixed 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 sewn and fixed to the right end of the male hook-and-loop fastener 170 provided at the other end of the right shoulder band portion 70.

As shown in FIG. 7, when the left shoulder band portion 60 is worn, it has a portion that extends from the wearer's left shoulder toward the right belt portion 50 on the back side of the wearer. When the right shoulder band portion 70 is worn, it has a portion that extends from the wearer's right shoulder toward the left belt portion 40 on the back side of the wearer. 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.

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 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 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 to connect 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 wearer's back when worn. The back surfaces of the left and right belt portions 40, 50 are in contact with the wearer's torso when worn.

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 desired position of the female hook-and-loop fastener 110 provided at the right belt portion 50, 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 desired position of the female hook-and-loop fastener 110 provided at the left belt portion 40, 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 tensile strength of the left and right shoulder bands 60, 70 so that the left and right shoulder bands 60, 70 push the wearer's thoracic vertebrae forward from the back via the back support 10, while the left and right shoulder bands 60, 70 push the left and right shoulder blades from the front to the rear, opening the wearer's shoulder blades outward and ensuring the correct posture with the chest out.

As described above, the posture correction device 1 of the first embodiment includes a left belt portion 40, a right belt portion 50, a left shoulder band portion 60, and a 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 wearer's left shoulder 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.

When the left and right shoulder band parts 60, 70 of this posture correction device 1 are worn, they press down on the wearer's shoulders, so friction increases 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 this posture correction device 1, the parts of the left and right shoulder band parts 60, 70 that are located on the back side of the wearer's shoulders are pulled more strongly than the parts that are located 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 backrest 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, allowing the wearer to maintain a correct posture with their chest out. In addition, with this posture corrector 1, the right hand pulls the left shoulder band part 60, which transmits force to open the left shoulder blade outward, and the left hand pulls the right shoulder band part 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 parts 60, 70 will interfere with the movement of opening the left and right shoulder blades.

Therefore, the posture corrector 1 of Example 1 makes it easier for the wearer to maintain correct posture with their chest out.

When the posture corrector 1 of the first embodiment is worn, the left shoulder band portion 60 and the right shoulder band portion 70 cross over each other on the back side of the wearer. With this posture corrector 1, the crossing portion of the left shoulder band portion 60 and the right shoulder band portion 70 on the back side of the wearer can appropriately push the thoracic vertebrae forward via the back support portion 10. Therefore, this posture corrector 1 makes it easier for the wearer to maintain a correct posture.

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 in contact with 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 easier for the wearer to maintain a correct posture.

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 positions 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 putting on the posture corrector 1. Therefore, this posture corrector 1 can be put on properly, and the wearer is more likely to adopt a correct posture.

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 the appropriate direction, making it easy to put on.

The first guide portion 20 and the second guide portion 30 of the posture corrector 1 of the first embodiment are inserted diagonally 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 this 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.

The left shoulder band portion 60 and the right shoulder band portion 70 of the posture corrector 1 of Example 1 are more slippery than other portions due to the sliding member 130 fixed to the portion that passes through either the first guide portion 20 or the second guide portion 30. When the left and right shoulder band portions 60, 70 of this posture corrector 1 are worn, the portions that pass through the first guide portion 20 and the second guide portion 30 can move smoothly in the longitudinal direction. Therefore, when this posture corrector 1 is worn, the left and right shoulder band portions 60, 70 are prevented from twisting in the first guide portion 20 and the second guide portion 30, and it can be worn easily.

The left belt portion 40 and the right belt portion 50 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 allows the left and right belt portions 40, 50 to fit appropriately to the torso by the elastic force of the left and right belt portions 40, 50.

The left shoulder band portion 60 and the right shoulder band portion 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 allows the left and right shoulder band portions 60, 70 to fit the wearer appropriately due to the elastic force of the left and right shoulder band portions 60, 70. In addition, this posture corrector 1 allows the thoracic vertebrae to be pushed forward by the strong elastic force, since the portions 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 portions located on the chest side of the wearer's shoulders.
