Description

Technical Field

[0001] This application belongs to the field of medical assistive device technology, and more specifically, relates to a posture corrector belt. Background Technology

[0002] A posture corrector is a device that is used to correct body posture. Its basic function is to correct upper body posture, keep the upper body straight, and improve the user's hunchback.

[0003] In related technologies, posture correctors include a waist belt, a back section, and shoulder straps. One end of the shoulder strap is fixed to the edge of the waist belt along its width, while the other end crosses over the shoulder from the front of the chest and extends to the opposite arm area. Users can adjust the tightness of the shoulder strap by pulling on the other end, making it fit more snugly in the shoulder area, thus enhancing the corrective effect on upper body posture. However, with this method, when the shoulder strap is tightened, because one end of the shoulder strap is fixed to the waist belt, the tension is transmitted through the shoulder strap to the waist belt, causing the waist belt to shift upwards, potentially compressing the abdomen or rib area and causing discomfort. Utility Model Content

[0004] The purpose of this application is to provide a posture correction belt to solve the technical problem in the prior art where pulling the shoulder straps causes the waist belt to move upwards.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows: a posture correction belt is provided, comprising: a waist belt; a back strap connected to the waist belt; two shoulder straps, each shoulder strap having a first end and a second end; and a limiting member having a channel; wherein, the first ends of the two shoulder straps are connected to the back strap, the second ends of the two shoulder straps are used to extend to the underarm area of ​​the human body and extend upward along the contour of the human shoulder to the back, and the second ends of the two shoulder straps are movably inserted through the channel and slidably disposed along the channel.

[0006] In one alternative embodiment, the limiting member is attached to the shoulder strap.

[0007] In one alternative embodiment, the first ends of the two shoulder straps are connected to the top region of the back strap, and the limiting member is connected to the bottom region of the back strap; or, the first ends of the two shoulder straps are connected to the bottom region of the back strap, and the limiting member is connected to the top region of the back strap; or, the orthographic projection area of ​​the limiting member on the back strap at least partially overlaps with the orthographic projection area of ​​the first ends of the two shoulder straps on the back strap; or, the orthographic projection area of ​​the limiting member on the back strap covers the orthographic projection area of ​​the first ends of the two shoulder straps on the back strap; or, the orthographic projection area of ​​the first ends of the two shoulder straps on the back strap covers the orthographic projection area of ​​the limiting member on the back strap.

[0008] In an alternative embodiment, the first ends of the two shoulder straps form a first included angle α with the opening facing downwards, and the range of the first included angle α is: α≤180°.

[0009] In an alternative embodiment, the first ends of the two shoulder straps are connected to the back strap at a distance, and a second included angle β with the opening facing downwards is formed between the reverse extension lines of the first ends of the two shoulder straps, and the range of the second included angle β is: α≤180°.

[0010] In one alternative embodiment, the second ends of the two shoulder straps cross and pass through the channel.

[0011] In one alternative embodiment, the channel includes a first channel and a second channel that are arranged in a cross manner, and the second ends of the two shoulder straps pass through the first channel and the second channel respectively, and are slidably arranged along the first channel and the second channel respectively; or, the limiting member includes at least two limiting buckles, which are spaced apart and connected to one of the first end of the shoulder strap, the back strap and the waist belt, and the limiting buckles are provided with channels, through which the second ends of the two shoulder straps pass.

[0012] In one alternative embodiment, the first ends of the two shoulder straps are symmetrically arranged about the center line of the back strap along the height direction.

[0013] In one alternative embodiment, the second end of the shoulder strap passes through the channel and is detachably connected to the waist belt; or, the second end of the shoulder strap is provided with a first connecting portion, the middle region of the shoulder strap is provided with a second connecting portion, and the second end of the shoulder strap passes through the channel and is detachably connected to the first connecting portion and the second connecting portion; or, the second ends of the two shoulder straps are detachably connected to each other.

[0014] In one alternative embodiment, the waist belt and the back strap are integrally formed; the posture correction belt also includes a support strip, which is embedded in the waist belt and the back strap along the height direction.

[0015] The beneficial effects of the posture corrector belt provided in this application are as follows: Compared with the prior art, the posture corrector belt in this application connects the first end of the shoulder strap to the back strap, and the second end of the shoulder strap extends to the armpit area of ​​the human body and extends upward along the contour of the human shoulder to the back, passing through the channel of the limiting member. When the second end of the shoulder strap is pulled, since the shoulder strap is connected to the back strap, the force direction of the first end of the shoulder strap is more horizontal rather than vertically upward. The pulling force mainly acts on the back strap and will not cause the waist belt to rise, effectively preventing the waist belt from shifting upward, reducing the pressure on the waist, abdomen, ribs and other parts, and improving the wearing stability and comfort. The second end of the shoulder strap passes through the channel of the limiting member and can slide and adjust. Users can flexibly adjust the length and tension of the shoulder strap according to their own needs, making it easy to adjust the tightness and adapt to different body types. When the two shoulder straps are tightened, they can more effectively pull the shoulders back, improve hunchback and improve the overall posture adjustment effect. Attached Figure Description

[0027] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0028] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on or indirectly on that other component. When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

[0029] It should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0030] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0031] A posture corrector is a device that is used to correct body posture. Its basic function is to correct upper body posture, keep the upper body straight, and improve the user's hunchback.

[0032] In related technologies, posture correctors include a waist belt, a back section, and shoulder straps. One end of the shoulder strap is fixed to the edge of the waist belt along its width, while the other end crosses over the shoulder from the front of the chest and extends to the opposite arm area. Users can adjust the tightness of the shoulder strap by pulling on the other end, making it fit more snugly in the shoulder area, thus enhancing the corrective effect on upper body posture. However, with this method, when the shoulder strap is tightened, because one end of the shoulder strap is fixed to the waist belt, the tension is transmitted through the shoulder strap to the waist belt, causing the waist belt to shift upwards, potentially compressing the abdomen or rib area and causing discomfort. It may even affect the overall stability of wearing the garment, causing the posture corrector to slip or tilt, reducing the corrective effect; the waist belt may also cause the shoulder straps and back to shift, making the two shoulder straps loose and unable to maintain the correct force points, weakening or eliminating the stretching effect of the shoulder straps on the shoulders; in addition, when the waist belt moves upward to a certain position under the pull of the shoulder straps, it will be stuck and unable to move further upward. If the end of the shoulder strap is pulled at this time, the waist belt will exert a downward reaction force on the shoulder strap, causing the shoulder strap to tend to pull down under the action of this force, thus causing the user's shoulders to be subjected to downward pressure, creating a feeling of shoulder pressure.

[0033] In other related technologies, the shoulder straps are wrapped around the back, then forward across the shoulders, down around the armpits, and finally back to the back. The problem with this design is that it does not fully consider the interaction between the shoulder strap and the shoulder when the strap moves. When the user pulls the end of the strap, the strap moves forward relative to the shoulder, creating a forward frictional force on the shoulder, causing the shoulder to curl inward and exacerbating the user's hunched shoulder problem.

[0034] Please refer to the following: Figures 1 to 8 The posture correction belt 100 provided in this application embodiment will now be described. The posture correction belt 100 includes a waist belt 10; a back strap 20 connected to the waist belt 10; two shoulder straps 30, each shoulder strap 30 having a first end 31 and a second end 32 opposite to each other; and a limiting member 40, the limiting member 40 having a channel 41; wherein, the first ends 31 of the two shoulder straps 30 are connected to the back strap 20, the second ends 32 of the two shoulder straps 30 are used to extend to the armpit area of ​​the human body and extend upward along the contour of the human shoulder to the back, the second ends 32 of the two shoulder straps 30 are movably passed through the channel 41 and are slidably arranged along the channel 41.

[0035] The waist belt 10 refers to an adjustable or fixed belt that wraps around the waist area of ​​the human body, used to provide basic support and fix the posture correction belt 100 in the waist position. The waist belt 10 can be made of elastic fabric. The two ends of the waist belt 10 can be connected by Velcro or buckles.

[0036] The shoulder strap 20 refers to a strip or sheet-like structure connected to the waist belt 10 and covering the back area of ​​the human body, used to transmit the tension of the shoulder strap 30 and distribute pressure. The shoulder strap 30 can be made of branched fabric integrally formed with the waist belt 10, or it can be a separately sewn component.

[0037] The shoulder straps 30 are provided in two separate sections, one for each side of the body. The first end 31 of each shoulder strap 30 is fixed to the back strap 20, and the second end 32 extends to the underarm area and then along the shoulder contour to the back, distributing shoulder pressure through a designed path. The first end 31 of the shoulder straps 30 is fixed to the back strap 20 by sewing or using buckles. The shoulder straps 30 can be made of elastic webbing, non-elastic webbing, or adjustable webbing.

[0038] The limiting member 40 has a channel 41, which refers to a fixing component with a through hole or ring structure. The channel 41 allows the second end 32 of the shoulder strap 30 to slide through, adjusting the length and direction of tension of the shoulder strap 30 and preventing the tension from being concentrated and transmitted to the waist belt 10. The limiting member 40 can be made of sewn fabric loops, plastic buckles, or metal rings. The limiting member 40 can restrict the degree of freedom of the shoulder strap 30 passing through the channel 41 in the direction perpendicular to the human body to near the main plane of the posture correction belt 100.

[0039] When a user wears the posture corrector 100, the waist belt 10 is fixed to the waist, the back strap 20 fits the back, and the shoulder strap 30 extends from the back to the armpit, then around the shoulder and back to the back. The second end 32 of the shoulder strap 30 extends to the armpit and along the shoulder contour to the back, better conforming to the human shoulder and armpit structure and preventing the shoulder strap 30 from slipping or shifting; the extension path conforms to the shoulder curve, improving wearing comfort. The second end 32 of the shoulder strap 30 passes through the channel 41 of the limiting member 40 and can slide within the channel 41, which can more effectively apply backward and inward pulling force, helping the shoulders to naturally extend backward, thereby improving the correction effect. The shoulder strap 30 follows the shoulder curve, making the direction of pulling force more matched with the shoulder muscles and bone structure, improving the naturalness and comfort of the correction. In addition, the second end 32 of the shoulder strap 30 can extend to the hand area after passing through the channel 41 of the limiting member 40, allowing the hand to pull the shoulder strap 30 to adjust its tightness.

[0040] The force point of the shoulder strap 30 is transferred from the waist belt 10 to the back strap 20, avoiding the vertical tension transmission to the waist belt 10 when the shoulder strap 30 is tightened. When the shoulder strap 30 is tightened, the tension mainly acts on the back area, rather than being transmitted to the waist belt 10. This prevents the waist belt 10 from shifting upwards due to tension and compressing the abdomen or ribs, and also prevents the shoulder strap 30 and back strap 20 from shifting, thus avoiding a weakening of the corrective effect due to the shoulder strap 30 becoming loose. The back strap 20 is located on the back of the body, closer to the areas that need correction (scapular region, thoracic spine region), so that the posture corrective force is more concentrated on the back, and the corrective effect is more direct and effective. After adjusting the tightness of the shoulder strap 30, the shoulder strap 30 can be fixed to the waist belt 10, or the second ends 32 of the two shoulder straps 30 can be connected to each other.

[0041] The second end 32 of the shoulder strap 30 passes through the channel 41 of the limiting member 40 and is adjustable, providing a sliding adjustment function so that users can flexibly adjust the tightness of the shoulder strap 30 according to their own body shape and needs. The limiting member 40 plays a guiding and fixing role, preventing the shoulder strap 30 from slipping or misaligning, and enhancing wearing stability. The sliding structure allows the shoulder strap 30 to move freely within a certain range, and automatically adjusts to the most suitable force position when tightened, enhancing fit and corrective effect.

[0042] Compared with the prior art, the posture corrector strap 20 provided in this application embodiment connects the first end 31 of the shoulder strap 30 to the back strap 20, and the second end 32 of the shoulder strap 30 extends to the armpit area of ​​the human body and upward along the contour of the human shoulder to the back, passing through the channel 41 of the limiting member 40. When the second end 32 of the shoulder strap 30 is pulled, since the shoulder strap 30 is connected to the back strap 20, the force direction of the first end 31 of the shoulder strap 30 is more horizontal rather than vertically upward, and the pulling force mainly acts on the back strap 20. This design prevents the waist belt 10 from lifting, effectively avoiding its upward movement and reducing pressure on the waist, abdomen, ribs, and other areas, thus improving wearing stability and comfort. The second end 32 of the shoulder strap 30 passes through the channel 41 of the limiting piece 40 and can be slidably adjusted. Users can flexibly adjust the length and tension of the shoulder strap 30 according to their own needs, making it easy to adjust the tightness and fit different body types. When the two shoulder straps 30 are tightened, they can more effectively pull the shoulders back, improve hunchback and enhance the overall posture adjustment effect.

[0043] Please refer to some embodiments of this application. Figure 1 The limiting member 40 is connected to the shoulder strap 20.

[0044] The limiting member 40 is fixed on the shoulder strap 20 to form a stable traction point. The second end 32 of the shoulder strap 30 slides and adjusts after passing through the limiting member 40, making it less likely to slip off or become misaligned.

[0045] All the force on the shoulder straps 30 is ultimately concentrated on the back straps 20, not the waist belt 10. Since the back straps 20 are located on the back, the force direction is more horizontal, preventing vertical displacement. This avoids the transmission of tension to the waist belt 10 when the shoulder straps 30 are tightened, thus preventing the waist belt 10 from shifting upwards or lifting. For example, when the limiting piece 40 is sewn into the middle area of ​​the back straps 20, the sliding path of the second end 32 of the shoulder straps 30, extending from the armpit to the back, is restricted within the coverage area of ​​the back straps 20. At this time, the back straps 20 evenly distribute the tension by conforming to the back of the body, avoiding localized pressure concentration.

[0046] The limiting member 40 can be connected to the top, bottom or middle area of ​​the shoulder strap 20; the limiting member 40 and the shoulder strap 20 can be fixed by sewing, gluing or buckling; the limiting member 40 can form a rigid or flexible connection with the shoulder strap 20 to adapt to different back curvatures.

[0047] The limiting member 40 can be a plastic part with a channel 41, which is directly embedded into the fabric structure of the shoulder strap 20 by hot pressing; the limiting member 40 can also be fabric, which is directly sewn onto the surface of the shoulder strap 20; or it can be a metal ring, which is firmly sewn onto the surface of the shoulder strap 20 by stitching.

[0048] The limiting component 40, fixed to the carrying strap 20, ensures that the sliding path of the second end 32 of the shoulder strap 30 is always symmetrically distributed around the central axis of the back, thereby enhancing the effect of pulling the shoulders back and improving posture correction efficiency. The secure connection between the limiting component 40 and the carrying strap 20 ensures smooth sliding of the shoulder strap 30 as it passes through the limiting component 40. Thus, the posture correction belt 100 maintains structural stability during use, improving the durability of the corrective effect. Simultaneously, the connection between the limiting component 40 and the carrying strap 20 simplifies the overall structure of the posture correction belt 100, facilitating production and assembly and reducing manufacturing costs. Furthermore, this connection method enhances the durability of the posture correction belt 100, extending the product's lifespan.

[0049] In some embodiments of this application, the first ends 31 of the two shoulder straps 30 are connected to the top region of the back strap 20, and the limiting member 40 is connected to the bottom region of the back strap 20.

[0050] The top area can be understood as the area near the top of the shoulder strap 20, and the bottom area can be understood as the area near the bottom of the shoulder strap 20. They can also be divided along a horizontal center line of the shoulder strap 20, which divides the shoulder strap 20 into two equal parts: the upper part is the top area, and the lower part is the bottom area. By limiting the relative position of the first end 31 of the shoulder strap 30 and the limiting member 40, the extension path and force direction of the shoulder strap 30 on the shoulder strap 20 can be adjusted. The first end 31 of the shoulder strap 30 is fixed to the top area of ​​the shoulder strap 20, and the limiting member 40 is located in the bottom area of ​​the shoulder strap 20, forming a separate upper and lower layout. The shoulder strap 30 extends downwards from the top to the limiting member 40, and the pulling force is distributed along the height of the shoulder strap 20, reducing direct traction on the waist belt 10.

[0051] The shoulder strap 30 is connected to the top of the back strap 20, and the limiting member 40 is at the bottom of the back strap 20, forming two force points at the top and bottom. When the shoulder strap 30 is tightened, it will generate a backward torque around the back strap 20, effectively pulling the shoulders backward and straightening the back. The limiting member 40 is located at the bottom of the back strap 20, providing a lower traction fulcrum for the second end 32 of the shoulder strap 30, which facilitates sliding adjustment and tension control. When the end of the shoulder strap 30 is pulled, the direction of the pulling force tends to be horizontal. Through the guiding effect of the limiting member 40, the tension can be distributed more evenly on the shoulders and back, making the adjustment more sensitive and effective.

[0052] Please refer to some embodiments of this application. Figure 1 and Figure 4 The first ends 31 of the two shoulder straps 30 are connected to the bottom area of ​​the back strap 20, and the limiting member 40 is connected to the top area of ​​the back strap 20.

[0053] The first end 31 of the shoulder strap 30 is fixed to the bottom of the back strap 20, and the limiting piece 40 is located at the top. When the shoulder strap 30 is tightened, the pulling force is from bottom to top, which helps to naturally pull the shoulder backward and upward. The upward pulling force is more in line with the natural movement trend of the human scapula (scapular upward rotation and retraction), making it easier to open the shoulder and improve problems such as rounded shoulders and hunched back. The shoulder strap 30 runs from bottom to top, which fits the curve of the armpit and shoulder more closely and reduces the risk of slipping, making it especially suitable for sports or frequent activities. At the same time, the upward pulling force makes the back muscles more evenly stressed, reduces local pressure, and improves the comfort of wearing for a long time.

[0054] In some embodiments of this application, the orthographic projection area of ​​the limiting member 40 on the shoulder strap 20 at least partially overlaps with the orthographic projection area of ​​the first end 31 of the two shoulder straps 30 on the shoulder strap 20.

[0055] The first end 31 of the shoulder strap 30 is fixed close to the position of the limiting member 40, which makes the tension path of the shoulder strap 30 shorter and more concentrated, improving the transmission efficiency of the corrective force. That is, when the projection area of ​​the limiting member 40 and the shoulder strap 30 overlaps, the point of force application can be concentrated, enhancing the local correction effect. The shoulder strap 30 starts from a certain point of the back strap 20, passes through the limiting member 40 and is tightened. The path is short and concentrated, the force is more direct, energy loss is reduced, and it helps to form symmetrical traction force, making the shoulders more naturally extended and the effect of correcting hunchback, rounded shoulders and other postures more obvious.

[0056] The limiting member 40 is close to the fixing point of the shoulder strap 30, which can effectively control the sliding path of the shoulder strap 30 and prevent the shoulder strap 30 from shifting or slipping. The structure is concentrated on the back strap 20, and the tension of the shoulder strap 30 is concentrated in a local area of ​​the back strap 20. In particular, when the starting point of the shoulder strap 30 coincides with or is close to the limiting member 40, the direction of the tension tends to be horizontal, avoiding the tension from being transmitted to the waist belt 10 and preventing the waist belt 10 from lifting, thereby reducing the pressure on the abdomen and ribs.

[0057] In some embodiments of this application, the orthographic projection area of ​​the limiting member 40 on the shoulder strap 20 covers the orthographic projection area of ​​the first ends 31 of the two shoulder straps 30 on the shoulder strap 20.

[0058] The limiting member 40 can be designed to be larger in size, so that its projected area on the back strap 20 is larger than the projected area of ​​the first end 31 of the shoulder strap 30. When viewed from the back, the projection of the limiting member 40 completely covers the projection of the first end 31 of the shoulder strap 30. When the projected area of ​​the limiting member 40 covers the shoulder strap 30, the range of force can be dispersed, improving comfort.

[0059] The starting point of the shoulder strap 30 is located within the projection area of ​​the limiting member 40. The path from the starting point of the shoulder strap 30 to the limiting member 40 is relatively short, which helps to form a uniform traction force, enhances the effect of pulling the shoulders back, and significantly improves problems such as hunchback, rounded shoulders, etc.

[0060] The shoulder strap 30 starts close to the limiting piece 40, resulting in a shorter sliding path, more sensitive adjustment, and more direct feedback, making it easier for users to adjust the tightness according to their body shape. At the same time, the shoulder strap 30's starting point and the limiting piece 40 are integrated into one area, reducing the complexity and bulk of the back structure and improving the fit and lightness when wearing the garment. The tension direction of the shoulder strap 30 is nearly horizontal, preventing the waist belt 10 from lifting and reducing pressure.

[0061] In some embodiments of this application, the orthographic projection area of ​​the first ends 31 of the two shoulder straps 30 on the back strap 20 covers the orthographic projection area of ​​the limiting member 40 on the back strap 20.

[0062] The limiting member 40 is surrounded by the starting point of the shoulder strap 30 and is subjected to traction forces from both sides, making its structure more stable and less prone to swaying or shifting. As the center point of the sliding channel 41, the limiting member 40 makes the sliding path of the two shoulder straps 30 more symmetrical, and the traction force is applied more evenly to both shoulders, preventing slippage on one side or uneven tension.

[0063] The shoulder strap 30 is pulled from the outside in, conforming to the curve of the human shoulder, reducing the risk of slippage or pressure, and improving wearing comfort. The outward pulling force is more in line with the natural force direction of the shoulder muscles, making the shoulder strap 30 fit the underarm and shoulder contours better, reducing local pressure.

[0064] The shoulder strap 30 has a horizontal tension direction, which will not cause the waist belt 10 to lift. The back strap 20 acts as a "force-bearing platform" to bear the traction force. The structure is concentrated on the back strap 20, and the tension is concentrated in the back area and not transmitted to the waist belt 10, thus avoiding compression of the abdomen or ribs. When the projection area of ​​the shoulder strap 30 covers the limiting member 40, the force-bearing area of ​​the shoulder strap 30 can be increased, improving the stability of the correction.

[0065] Please refer to some embodiments of this application. Figure 1 The first ends 31 of the two shoulder straps 30 form a first included angle α with the opening facing downwards, and the range of the first included angle α is: α≤180°.

[0066] "Opening downwards" refers to the opening facing downwards when worn, with the human body as the reference point. The first ends 31 of the two shoulder straps 30 are connected in a V-shape on the back strap 20. The first included angle α can be set to 120°, 90°, 160°, etc.

[0067] The shoulder straps 30 open outwards to form an angle α, causing the traction force of the two shoulder straps 30 on the shoulders to tend to expand outwards, which helps to open the chest cavity and correct rounded shoulders. When the shoulder straps 30 extend outwards at a certain angle, their pulling force tends to pull the shoulders backwards and outwards, forming a symmetrical reverse traction force, which enhances the effect of shoulder retraction.

[0068] In addition, the human shoulder has an outward tilt structure, and the outward opening angle of the shoulder strap 30 is more in line with the natural direction of the shoulder, reducing local pressure and the risk of slipping; the outward opening angle makes the shoulder strap 30 fit the armpit and shoulder curves better, improving the fit and comfort of wearing.

[0069] When the two shoulder straps 30 are distributed at a certain angle, a "symmetrical traction zone" is formed during the sliding adjustment process, making the force on both shoulders more balanced and avoiding misalignment caused by excessive sliding on one side or uneven tension. The outward flare angle of the shoulder straps 30 helps to distribute the tension evenly in the area of ​​the back strap 20, reducing local stress concentration.

[0070] Furthermore, at this point, the longitudinal resultant force of the first ends 31 of the two shoulder straps 30 is already downward, so no matter how the user moves, the user's waist belt 10 will not move. The force applied by the user to the shoulder straps 30 is entirely used for opening the shoulders and does not cause any energy waste in the longitudinal direction.

[0071] In some embodiments of this application, the first ends 31 of the two shoulder straps 30 are connected to the back strap 20 at intervals, and a second included angle β with an opening facing downwards is formed between the reverse extension lines of the first ends 31 of the two shoulder straps 30, and the range of the second included angle β is: α≤180°.

[0072] The shoulder straps 30 are spaced out at their starting points, forming a certain angle β. The second angle β can be set to 120°, 90°, 160°, etc. This setting helps to form a stable sliding path, making it easy to adjust the tightness of the shoulder straps 30.

[0073] At this point, the combined longitudinal force at the first ends 31 of the two shoulder straps 30 is downward, so no matter how the user moves, the user's waist belt 10 will not move. The force applied by the user to the shoulder straps 30 is entirely used for shoulder opening and does not result in any energy waste in the longitudinal direction.

[0074] The shoulder straps 30 distribute tension across different areas of the back straps 20, preventing them from slipping or causing localized pressure due to concentrated force. When the user adjusts the tightness of the shoulder straps 30, the tension is more evenly distributed across the back area, reducing the upward lifting force on the waist belt 10 and preventing it from shifting upwards and causing pressure on the abdomen or rib area. This design also improves the comfort and stability of the posture corrector belt 100, making the posture correction effect more significant.

[0075] Please refer to some embodiments of this application. Figure 1 The second ends 32 of the two shoulder straps 30 are crossed and threaded through the channel 41.

[0076] When the shoulder straps 30 are crossed, the pulling force is symmetrically distributed in a crisscross pattern, which helps the shoulders to symmetrically pull back, significantly improving poor posture such as rounded shoulders and hunchback. The crisscross structure allows the two shoulder straps 30 to form symmetrical opposing traction forces on the back, effectively opening the chest cavity and straightening the spine. After one shoulder strap 30 passes through the limiting member 40 channel 41, the other strap passes through from the other side, forming a mutually restraining structure that enhances path control during wear.

[0077] When the user adjusts the tightness of the shoulder straps 30, the second ends 32 of the two shoulder straps 30 slide synchronously along the channel 41 in a cross-threaded state. The cross structure makes the two shoulder straps 30 mutually restrain each other, preventing the shoulder strap 30 on one side from shifting due to overstretching. When worn, the symmetrical traction force generated by the cross-threading is evenly transmitted to the waist area through the back straps 20, preventing the waist belt 10 from shifting upwards due to unilateral force on the posture correction belt 100. The cross-threading method further optimizes the movement trajectory of the shoulder straps 30 in the channel 41, ensuring that the two shoulder straps 30 remain symmetrically distributed during sliding, thereby improving the stability of the posture correction belt 100 in wrapping the shoulder area of ​​the human body.

[0078] The crisscross structure allows the shoulder strap 30 to conform more naturally to the armpit, shoulder, and back, preventing it from slipping or getting stuck in the acromion or collarbone area. The shoulder strap 30's crisscrossing design within the channel 41 of the limiting member 40 enhances the limiting member 40's control over the shoulder strap 30, making its sliding path more stable. This crisscrossing design allows the limiting member 40 to control both shoulder straps 30 simultaneously, improving its guiding and limiting functions and preventing the shoulder strap 30 from shifting or becoming misaligned.

[0079] Please refer to some embodiments of this application. Figure 3 The channel 41 includes a first channel 411 and a second channel 412 that are arranged in a cross manner. The second ends 32 of the two shoulder straps 30 pass through the first channel 411 and the second channel 412 respectively, and are slidably arranged along the first channel 411 and the second channel 412 respectively.

[0080] Two intersecting channels 411 and 412 can be provided inside or on the surface of the limiting member 40; alternatively, the limiting member 40 can be fixed to the shoulder strap 20, retaining the through opening of the two channels 41, forming the first channel 411 and the second channel 412 by enclosing it with the shoulder strap 20. Alternatively, the limiting member 40 can be a rectangular plate structure with two intersecting channels 41 on the rectangular plate. The first channel 411 and the second channel 412 are intersected, with an intersection angle of 90 degrees or 120 degrees, etc. The width of the two channels 41 is slightly larger than the width of the shoulder strap 30, allowing the shoulder strap 30 to slide freely within the channels 41. The second end 32 of the shoulder strap 30 passes through one end of the first channel 411 and the second channel 412 respectively, and exits from the other end. Thus, the two shoulder straps 30 form an intersecting structure on the back, each independently guiding the sliding of one shoulder strap 30.

[0081] Each shoulder strap 30 has an independent channel 41, preventing two shoulder straps 30 from interfering with or tangling in the same channel 41. The independent channel 41 design makes the sliding path of each shoulder strap 30 clearer and more stable, reducing uneven sliding resistance or jamming caused by cross-threading. In dynamic use (such as sports), it is more conducive to maintaining the traction stability of the shoulder straps 30.

[0082] Each shoulder strap 30 slides through an independent channel 41, allowing users to adjust the tightness on both sides individually to accommodate different body types or asymmetrical postures. The intersecting structure of the dual channels 41 enables the limiting element 40 to more effectively guide the sliding direction of the shoulder straps 30, preventing them from slipping or veering off course. The intersecting channels 41 guide the shoulder straps 30 to form symmetrical traction, which helps to open the chest cavity, correct rounded shoulders, and improve hunchback.

[0083] In some embodiments of this application, the limiting member 40 includes at least two limiting buckles (not shown in the figure), which are spaced apart and connected to one of the first end 31 of the shoulder strap 30, the back strap 20 and the waist belt 10. The limiting buckles are provided with channels 41 through which the second ends 32 of the two shoulder straps 30 pass respectively.

[0084] The two locking buckle schemes provide independent sliding paths for the two shoulder straps 30 through a spatially separated channel 41 structure. The locking buckle can be a ring structure with channel 41 located at the center of the ring structure; alternatively, channel 41 can be formed by the locking buckle and the shoulder straps 30 enclosing each other.

[0085] The positioning buckles are spaced apart, forming two independent constraint points. When the shoulder straps 30 pass through different positioning buckles, their sliding paths naturally separate. Multiple positioning buckles can be set, arranged in two rows, allowing the second ends 32 of the two shoulder straps 30 to pass through multiple buckles respectively, forming a crisscross arrangement. By setting multiple positioning buckles, the limiting and guiding effect on the shoulder straps 30 is further enhanced, making the shoulder straps 30 form a more stable crisscross structure on the back. This achieves a crisscross arrangement of the shoulder straps 30 on the back, enhancing the support for the user's upper body. Simultaneously, the shoulder straps 30 can slide freely within the channel 41, allowing them to automatically adjust their tightness according to the user's body movements during use, improving the comfort and adaptability of the posture corrector 100.

[0086] Please refer to some embodiments of this application. Figure 1 The first ends 31 of the two shoulder straps 30 are symmetrically arranged about the center line of the back strap 20 along the height direction.

[0087] The midline of the shoulder strap 20 along its height direction, i.e., its longitudinal centerline, is located behind the spine or near the midline of the back. The first ends 31 of the two shoulder straps 30 are located on either side of the midline, in a mirror-symmetrical arrangement.

[0088] The specific implementation of symmetrical arrangement can be that the connection points of the first end 31 of the shoulder strap 30 are located at the same height on both sides of the center line and are equidistant from the center line; or the connection points of the first end 31 of the shoulder strap 30 are symmetrically distributed along both sides of the center line, forming a symmetrical angle or spacing. For example, the distance between two symmetrically arranged connection points on both sides of the center line of the back strap 20 is 5 cm to 10 cm, and they are located on the same horizontal line in the top or bottom area of ​​the back strap 20.

[0089] When the shoulder straps 30 are symmetrically set, the starting points of both shoulder straps 30 are connected to the back straps 20. At this time, the shoulder straps 30 are basically level with the underarms. The resultant force of the two shoulder straps 30 in the longitudinal direction of the human body is small, and the longitudinal component force is small, even close to zero. Therefore, the user's movement will not cause the back straps 20 to move upward. The force applied by the user to the shoulder straps 30 is all used to open the shoulders and does not cause energy waste in the longitudinal direction.

[0090] By symmetrically fixing the first ends 31 of the two shoulder straps 30 to both sides of the center line of the back strap 20, the direction and magnitude of the tension generated by the shoulder straps 30 in the shoulder area of ​​the human body tend to be consistent, thereby avoiding the overall displacement of the posture correction belt 100 or uneven force on the waist belt 10 due to excessive tension on one side. When the second end 32 of the shoulder strap 30 passes through the channel 41 of the limiting member 40 and extends along the contour of the human shoulder, the symmetrically set connection points can ensure that the shoulder straps 30 remain balanced during sliding, reducing the lateral traction force on the waist belt 10, and thus reducing the risk of the waist belt 10 shifting upward due to pressure. As a result, the posture correction belt 100 can evenly distribute pressure when correcting posture, improving wearing stability and comfort, while enhancing the symmetrical restraint effect on the shoulder area.

[0091] The symmetrical arrangement of the first end 31 of the shoulder strap 30 ensures that the traction force on both shoulders is completely symmetrical, which helps to open the chest cavity and correct rounded shoulders and hunchback. At the same time, the symmetrical structure further ensures that the shoulder strap 30 fits the human shoulder with consistent tightness on both sides, improving the stability of posture maintenance during the correction process.

[0092] Please refer to some embodiments of this application. Figure 8 The second end 32 of the shoulder strap 30 passes through the channel 41 and is detachably connected to the waist belt 10.

[0093] The shoulder strap 30 and waist belt 10 are detachably connected, allowing users to freely adjust the length or connection position of the shoulder strap 30 according to their body type, clothing thickness, or correction needs. The second end 32 of the shoulder strap 30 connects to the waist belt 10, forming a complete "back strap 20—shoulder strap 30—waist belt 10" traction system, enhancing the overall structural stability and traction distribution. This structure helps improve back straightness, prevents the shoulder strap 30 from slipping, and enhances the corrective effect.

[0094] The detachable connection can be achieved through buckles, Velcro, straps, etc. The shoulder strap 30 achieves a self-locking function through the detachable connection structure, which maintains the corrective force in the shoulder area and eliminates the displacement tendency of the waist belt 10 caused by the tension of the shoulder strap 30, thereby significantly reducing the pressure on the abdomen and ribs.

[0095] In some embodiments of this application, the second end 32 of the shoulder strap 30 is provided with a first connecting portion, and the middle region of the shoulder strap 30 is provided with a second connecting portion. The second end 32 of the shoulder strap 30 passes through the channel 41 and is detachably connected to the second connecting portion through the first connecting portion.

[0096] The first connecting part is located at the second end 32 of the shoulder strap 30, and can be configured as a buckle, magnetic closure, Velcro, snap fastener, etc. The second connecting part is located in the middle area of ​​the shoulder strap 30 and is used to cooperate with the first connecting part.

[0097] After the second end 32 of the shoulder strap 30 passes through the channel 41 of the limiting member 40, it is connected to the second connecting part in the middle through the first connecting part to form a closed loop structure, which can realize the self-locking adjustment of the length of the shoulder strap 30.

[0098] Users can lock the current tension by simply tightening the shoulder strap 30 and fastening the first and second connecting parts. The central connection of the shoulder strap 30 ensures more even distribution of tension, reducing pressure on specific areas of the shoulder or back. The detachable connection allows users to quickly put on and take off the posture corrector 100 and make minor adjustments based on body shape or the thickness of clothing.

[0099] In some embodiments of this application, the second ends 32 of the two shoulder straps 30 are detachably connected to each other.

[0100] The two shoulder straps are connected at their 30-degree ends to form a symmetrical traction structure, which helps the shoulders to naturally extend backward and significantly improves poor posture such as hunchback, rounded shoulders, and slouching.

[0101] The second ends 32 of the two shoulder straps 30 can be freely connected and separated by means of buckles, magnets, Velcro, snaps, straps, etc.

[0102] The shoulder strap 30 forms a closed loop structure after the ends are connected, which enhances the stability of the overall structure and prevents the shoulder strap 30 from slipping or deviating. No additional waist belt 10 or back strap 20 is required as a connection point. Traction can be achieved simply by connecting the ends of the shoulder strap 30, which simplifies the overall structure.

[0103] The detachable connection supports multiple adjustment levels, allowing users to freely adjust the shoulder strap tightness according to their body type, clothing thickness, or correction intensity. The connection point can be designed with multiple buckle holes or adjustable Velcro for easy multi-level tension control. The detachable connection also makes it easier for users to put on and take off the posture corrector, and facilitates cleaning, component replacement, or localized adjustments.

[0104] Please refer to some embodiments of this application. Figure 2 The waist belt 10 and the back strap 20 are integrally formed; the posture correction belt 100 also includes a support strip 50, which is embedded in the waist belt 10 and the back strap 20 along the height direction.

[0105] The waist belt 10 and the back strap 20 are integrally molded. This integral molding structure uses continuous material or a seamless connection process to form the overall frame of the waist belt 10 and back strap 20, eliminating stress concentration points at the joints. The support strip 50, made of rigid or semi-rigid material, extends longitudinally along the midline of the back and is embedded within the interlayer of the waist belt 10 and back strap 20, extending to the lower edge of the waist belt 10 and the top area of ​​the back strap 20 at both ends. The waist belt 10 and back strap 20 wrap the support strip 50 using hot pressing, sewing, or injection molding processes, thus fixing the support strip 50 to the overall structure.

[0106] The one-piece molded structure creates a continuous force transmission path between the waist belt 10 and the back strap 20. When the shoulder strap 30 applies tension, the tension is evenly distributed to the waist belt 10 through the back strap 20, preventing deformation caused by localized stress. The support bar 50 is embedded in the waist belt 10 and back strap 20 along the height direction, enhancing the longitudinal bending stiffness of the overall structure and limiting the waist belt 10 from curling upwards or shifting laterally under stress. The combined design of the support bar 50 and the one-piece molded structure allows the posture corrector 100 to maintain its corrective effect while reducing localized pressure on the user's torso, thus improving wearing comfort.

[0107] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
