Description

Technical Field

[0001] This utility model relates to the field of orthopedic devices, and in particular, to an invisible posture corrector. Background Technology

[0002] Posture correctors, as products designed to help correct human posture, are widely used to improve poor posture, such as hunchback and rounded shoulders. However, there are still some problems with the design and use of currently available invisible posture correctors.

[0003] On the one hand, many invisible posture correctors have poorly designed shoulder straps, placing them close to the armpit area and causing discomfort such as "pulling under the armpit" during use. For example, the invisible posture corrector in existing technology CN201631437U has a small armhole space, which creates significant pressure on the armpit area and affects user comfort. Furthermore, the shoulder strap crossing section in this technology uses two sets of cross-woven webbing. While this structure provides some support and correction, the adjustment space is relatively small, and the overall structure is complex.

[0004] On the other hand, the existing invisible posture corrector belt in technology CN213217966U also has similar problems. Its armhole space is also relatively small, which can easily cause "underarm constriction" when worn. These problems not only affect the user experience, but also limit the promotion and application of invisible posture correctors to some extent.

[0005] In conclusion, existing invisible posture correctors have many shortcomings in shoulder strap design, failing to meet users' needs for comfort and functionality, and urgently require improvement and optimization. Utility Model Content

[0006] This invention provides a posture correction belt that moves the first connection point X forward, its position corresponding to the position of the serratus anterior muscle in the human body, thereby expanding the area of ​​the armpit space and reducing the force on the ribs, thus solving the technical problem of discomfort under the armpit.

[0007] This utility model provides a posture corrector belt, including a waist belt and shoulder straps. The two shoulder straps are arranged symmetrically on the left and right sides and are arranged in a cross pattern on the back of the human body. The front end of the shoulder strap passes through the front of the human body and is connected to the waist belt at a first connection point X at the junction of the serratus anterior muscle and the pectoralis major muscle. The rear end of the shoulder strap passes through the shoulder of the human body and passes obliquely through the back of the human body, and is connected to the waist belt at a second connection point Z at the position of the latissimus dorsi muscle.

[0008] Furthermore, the curvature r of the shoulder strap at the first connection point X is 95 degrees to 110 degrees.

[0009] The straight-line distance between the apex Y of the shoulder strap at the human shoulder position and the second connection point Z is 20 cm to 24 cm.

[0010] The rear end of the shoulder strap passes sequentially through the first and second limiting straps from the vertex Y and is then adjustablely connected to the waist belt.

[0011] The first restraint strap is located at the intersection point W of the two shoulder straps; and / or the second restraint strap is located at the second connection point Z.

[0012] The straight-line distance h from the first connection point X to the second connection point Z is 1 / 3 to 2 / 3 of the straight-line distance g from the first connection point X to the vertex Y.

[0013] The distance between the first connection point X of the first shoulder strap and the first connection point X of the second shoulder strap is 39 cm-45 cm.

[0014] The width of the middle section of the shoulder strap is greater than the width of the two ends.

[0015] The width of the middle section of the shoulder strap is 6 cm to 7 cm; and / or the width of the front end and the width of the rear end of the shoulder strap are 4.5 cm to 5 cm.

[0016] The belt includes a back piece and a hook and loop fastener, with the hook side and the loop side of the hook and loop fastener located at opposite ends of the back piece; the width of the back piece is greater than the width of the hook and loop fastener; the width of the back piece is 8 cm to 12 cm, and / or the width of the hook and loop fastener is 5 cm to 7 cm.

[0017] This utility model has the following beneficial effects:

[0018] This novel posture corrector features a cross-strap design that distributes force more evenly, reducing pressure on the shoulders and neck. This allows the strap tension to create a stable mechanical balance on the back, avoiding the discomfort caused by concentrated force in traditional posture correctors. By moving the first connection point X forward to the junction of the serratus anterior and pectoralis major muscles, the armpit space is expanded, reducing pressure on the ribs. This design effectively reduces stress concentration in the rib and armpit areas, thus solving the problem of armpit constriction. The connection point between the shoulder straps and waistband utilizes the lever principle. Through a reasonable distribution of mechanical fulcrums, the posture corrector can provide effective support and correction to the body with minimal external force. By applying force to the shoulders and back, the posture corrector forms a three-dimensional corrective force system, helping the body return to a neutral position and maintain good posture. This design not only effectively improves poor posture such as hunchback and rounded shoulders, but also... The optimized mechanical distribution reduces pressure on the body; the posture corrector provides dynamic and static support during wear, helping the spine restore its normal physiological curve. It's suitable not only for daily wear but also provides additional support during exercise, reducing fatigue. The second connection point Z at the latissimus dorsi muscle position on the shoulder straps allows for adjustable connection to the waist belt, enabling users to personalize the fit according to their body type and comfort needs. This adjustability not only improves the adaptability of the posture corrector but also ensures optimal mechanical performance and comfort in different usage scenarios. By optimizing the connection points and mechanical distribution of the shoulder and waist belts, the comfort and corrective effect of the posture corrector are significantly improved. The cross-strap design and optimized mechanical support point distribution allow the posture corrector to provide stable support and corrective force while dispersing pressure and optimizing stress distribution, effectively improving poor posture and reducing discomfort.

[0029] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, the present invention can be implemented in many different ways as defined and covered below.

[0031] like Figure 1 , Figure 2 and Figure 3As shown, the posture corrector belt of this embodiment includes a waist belt 100 and shoulder straps 200. The two shoulder straps 200 are arranged symmetrically on the left and right sides, and the two shoulder straps 200 are arranged in a crisscross pattern on the back of the human body. The front end of the shoulder strap 200 passes through the front of the human body and connects to the waist belt 100 at the first connection point X at the junction of the serratus anterior muscle and the pectoralis major muscle. The rear end of the shoulder strap 200 passes through the shoulder of the human body and passes obliquely through the back of the human body, and connects to the waist belt 100 at the second connection point Z at the position of the latissimus dorsi muscle. This novel posture corrector belt features a cross-strap design 200 that distributes force more evenly, reducing pressure on the shoulders and neck. This allows the tension of the straps 200 to create a stable mechanical balance on the back, avoiding the discomfort caused by concentrated force in traditional posture correctors. By moving the first connection point X forward to the junction of the serratus anterior and pectoralis major muscles, the armpit space is expanded, reducing pressure on the ribs. This design effectively reduces stress concentration in the rib and armpit areas, thus solving the problem of armpit constriction. The connection point between the shoulder straps 200 and the waist belt 100 utilizes the lever principle. Through a reasonable distribution of mechanical fulcrums, the posture corrector belt can provide effective support and correction to the body with minimal external force. By applying force to the shoulders and back, the posture corrector belt forms a three-dimensional corrective force system, helping the body return to a neutral position and maintain good posture. This design not only effectively improves poor posture such as hunchback and rounded shoulders but also... The mechanical distribution reduces pressure on the body; the posture corrector provides dynamic and static support during wear, helping the spine restore its normal physiological curve. It is suitable not only for daily wear but also provides additional support during exercise, reducing fatigue. The second connection point Z at the latissimus dorsi muscle position of the shoulder strap 200 is adjustable to the waist belt 100, allowing users to personalize the adjustment according to their body shape and comfort needs. This adjustability not only improves the adaptability of the posture corrector but also ensures optimal mechanical performance and comfort in different usage scenarios. By optimizing the connection point position and mechanical distribution of the shoulder strap 200 and waist belt 100, the comfort and corrective effect of the posture corrector are significantly improved. The design of the cross shoulder strap 200 and the reasonable distribution of mechanical support points enable the posture corrector to provide stable support and corrective force while dispersing pressure and optimizing stress distribution, thereby effectively improving poor posture and reducing physical discomfort.

[0032] like Figure 1 , Figure 2 and Figure 3As shown, in this embodiment, the arc r of the shoulder strap 200 at the first connection point X is 95 degrees to 110 degrees. The arc r of the shoulder strap 200 at the first connection point X, designed to be 95 to 110 degrees, can well conform to the natural curve of the junction of the serratus anterior and pectoralis major muscles, allowing the shoulder strap 200 to closely fit the contour of the chest when worn, avoiding instability and slippage caused by gaps between the shoulder strap 200 and the body. This arc range conforms to ergonomic principles, reducing the pressure of the shoulder strap 200 on the chest and underarm areas, thus significantly improving wearing comfort. The shoulder strap 200 can distribute pressure more evenly, utilizing the natural physiological curves of the human body, allowing the shoulder strap 200 to better distribute the tension from the waist belt 100 when worn. To avoid excessive local pressure, the shoulder strap 200 design within this arc range forms a stable mechanical support structure, helping the body maintain good posture while reducing pressure on the ribs and armpits. This arc range also better guides the body back to a neutral position. Through reasonable force distribution, the shoulder strap 200 provides continuous corrective force during daily activities, helping to improve poor posture such as hunchback and rounded shoulders. This design also reduces wearer fatigue because the pressure distribution of the shoulder strap 200 is more even, preventing discomfort during prolonged use. When the curvature of the shoulder strap 200 at the first connection point X is less than 95 degrees, the fit between the shoulder strap 200 and the chest is reduced, resulting in greater localized pressure on the chest and underarms, increasing the feeling of pressure. A shoulder strap with too little curvature cannot form a stable mechanical support structure, leading to poor corrective effect. The wearer may feel that the shoulder strap 200 does not fit the body well enough and cannot effectively guide the body back to a neutral position. Due to excessive localized pressure, the wearer will experience significant discomfort during prolonged use, affecting the wearing experience of the posture corrector. When the curvature of the shoulder strap 200 at the first connection point X is greater than 110 degrees, the fit between the shoulder strap 200 and the chest may be insufficient, making the shoulder strap 200 prone to slipping or shifting during wear. A shoulder strap with too much curvature cannot effectively distribute pressure, causing pressure to concentrate in certain areas, thus reducing the mechanical performance of the posture corrector. Due to the unsatisfactory fit and mechanical distribution of the shoulder strap 200, the corrective effect will be significantly affected. Wearers may find that the posture corrector provides insufficient support and is unable to effectively improve poor posture.

[0033] like Figure 1 , Figure 2 and Figure 3As shown, in this embodiment, the straight-line distance between the apex Y of the shoulder strap 200 at the human shoulder position and the second connection point Z is 20 cm to 24 cm. Within this range, the shoulder strap 200 provides stable mechanical support, forming a reasonable mechanical structure on the shoulder and back, effectively distributing pressure on these areas. This reasonable distance allows the shoulder strap 200 to better guide the shoulder and back muscles to exert force in the correct direction, thus correcting posture and helping to improve poor posture such as hunchback. The design of the shoulder strap 200 within this distance range better conforms to the natural curve of the human shoulder, reducing discomfort caused by the shoulder strap 200 being too long or too short. The appropriate straight-line distance ensures that the shoulder strap 200 does not exert excessive pressure on the shoulder and armpit areas when worn, thereby improving wearing comfort. (20 cm to 24 cm) The distance range allows for adaptation to users of different body types, especially teenagers and adults, meeting the needs of different heights and body shapes. This range also allows for some adjustment, enabling users to fine-tune the design according to their needs and comfort for a better wearing experience. However, when the straight-line distance between the apex Y of the shoulder strap 200 at the shoulder and the second connection point Z is less than 20cm, the shoulder strap 200 is too short, causing significant pressure on the shoulders and armpits, potentially leading to a feeling of compression and even affecting blood circulation. An excessively short shoulder strap 200 cannot provide sufficient mechanical support, resulting in poor correction and an inability to effectively improve poor posture. Furthermore, due to the short shoulder strap 200, wearers will experience significant discomfort during prolonged use, impacting the overall wearing experience of the posture corrector. When the straight-line distance between the apex Y of the shoulder strap 200 at the human shoulder position and the second connection point Z is greater than 24cm, the excessive length of the shoulder strap 200 will result in insufficient mechanical support, making it impossible to effectively guide the muscles of the shoulder and back to exert force in the correct direction, thereby reducing the corrective effect; the excessively long shoulder strap 200 is prone to sliding or shifting during wear, causing the posture corrector to be unable to maintain a stable support state; the excessively long shoulder strap 200 may not be suitable for users with smaller body size, resulting in a reduction in the universality of the posture corrector.

[0034] like Figure 1 , Figure 2 and Figure 3As shown, in this embodiment, the rear end of the shoulder strap 200 passes sequentially through the first limiting band 300 and the second limiting band 400 from the vertex Y and is then adjustablely connected to the waist belt 100. By having the shoulder strap 200 pass sequentially through the first limiting band 300 and the second limiting band 400, a multi-point support mechanical structure is formed, which can distribute the tension of the shoulder strap 200 to multiple support points, thereby improving the overall mechanical stability of the posture corrector. The limiting bands effectively prevent the shoulder strap 200 from sliding or shifting during wear, ensuring that the posture corrector maintains a stable support effect during long-term use. The connection between the shoulder strap 200 and the waist belt 100 via the first limiting band 300 and the second limiting band 400 can more evenly distribute the pressure on the shoulders and back, avoiding discomfort caused by concentrated pressure and improving wearing comfort. Guided by the limiting bands, the shoulder strap 200 can more effectively transmit corrective force to the shoulders and back, helping the body return to a neutral position and significantly improving poor posture such as hunchback and rounded shoulders. The limiting bands enable… This posture corrector can correct the body in multiple dimensions, not only correcting shoulder tilt but also effectively adjusting back curvature. The adjustable connection allows users to fine-tune it according to their needs and comfort, achieving optimal biomechanical distribution and corrective effect. The adjustable connection also allows for personalized adjustments based on body shape and comfort, improving the posture corrector's applicability and comfort. By optimizing biomechanical distribution and enhancing stability, it significantly reduces pressure on the shoulders and underarms, improving wearing comfort. The limiting straps disperse stress concentration points, reducing material fatigue and damage caused by excessive local stress, thus extending the posture corrector's lifespan. The multi-point support structure makes the posture corrector more stable during wear, effectively resisting external interference and improving product durability. After the shoulder strap 200 passes through the first limiting strap 300 and the second limiting strap 400 in sequence, it is adjustablely connected to the waist belt 100. This can significantly enhance the mechanical stability of the posture corrector, optimize the mechanical distribution, improve the corrective effect, enhance comfort and applicability, and at the same time enhance the durability of the structure. It can not only effectively improve poor posture, but also provide users with a more comfortable and stable wearing experience.

[0035] like Figure 1 and Figure 2As shown, in this embodiment, the first limiting strap 300 is located at the intersection point W of the two shoulder straps 200; and / or the second limiting strap 400 is located at the second connection point Z. The first limiting strap 300, located at the intersection point W of the two shoulder straps 200, effectively fixes the intersection position of the shoulder straps 200, preventing the intersection point W from sliding or shifting during use, making the intersection structure of the shoulder straps 200 more stable and better distributing pressure on the shoulders and back. By fixing the intersection point W, the first limiting strap 300 ensures that the tension of the shoulder straps 200 is evenly distributed on the shoulders and back, avoiding pressure concentration caused by the instability of the intersection point W, thereby improving wearing comfort. The second limiting strap 400, located at the second connection point Z, effectively fixes the connection position between the shoulder straps 200 and the waist belt 100, preventing... The connection points loosen or shift during use, making the connection between the shoulder strap 200 and the waist belt 100 more secure and improving the overall stability of the posture corrector belt. By fixing the second connection point Z, the second limiting strap 400 ensures that the tension of the shoulder strap 200 can be effectively transmitted to the waist belt 100, thereby enhancing the support effect on the body and helping to improve poor posture. The setting of the first limiting strap 300 and the second limiting strap 400 allows the posture corrector belt to provide stable support at multiple key points, thereby more effectively transmitting corrective force, helping the body return to a neutral position, and significantly improving poor posture such as rounded shoulders and hunchback. By fixing the intersection point W and the second limiting strap 400, the posture corrector belt can provide stable support at multiple key points, thereby more effectively transmitting corrective force, helping the body return to a neutral position, and significantly improving poor posture such as rounded shoulders and hunchback. At the second connection point Z, the posture corrector belt forms a stable mechanical support structure in the shoulders and back, ensuring even distribution and effective transmission of corrective force. The first limiting strap 300 and the second limiting strap 400 effectively prevent the shoulder strap 200 from slipping or shifting during wear, ensuring the posture corrector belt always fits the body and reducing discomfort caused by slippage. By fixing key points, the posture corrector belt better conforms to the natural curves of the human body, reducing pressure on the shoulders and underarms, thereby improving wearing comfort. The second limiting strap 400 at the second connection point Z allows users to personalize the adjustment according to their needs and comfort. The improved applicability of the posture corrector belt ensures optimal mechanical performance and comfort in various usage scenarios. By adjusting the second limiting strap 400, users can adjust the tension between the shoulder strap 200 and waist belt 100 according to their body shape and comfort needs, thereby achieving the best corrective effect. The design of the first limiting strap 300 and the second limiting strap 400 disperses stress concentration points, reducing material fatigue and damage caused by excessive local stress, thus extending the service life of the posture corrector belt. By fixing key points, the posture corrector belt is more stable during wear, effectively resisting external interference and improving product durability.

[0036] like Figure 3As shown, in this embodiment, the straight-line distance h from the first connection point X to the second connection point Z is 1 / 3 to 2 / 3 of the straight-line distance g from the first connection point X to the vertex Y. When the straight-line distance h from the first connection point X to the second connection point Z is 1 / 3 to 2 / 3 of the straight-line distance g from the first connection point X to the vertex Y, the posture correction belt can more reasonably distribute the force on the shoulders and back. This proportional design makes the pressure distribution of the shoulder strap 200 on the shoulders and back more even, reducing discomfort caused by excessive local pressure, thereby significantly improving the wearing comfort; within this proportional range, the structure of the posture correction belt can better guide the muscles of the shoulders and back to exert force in the correct direction, helping the body return to a neutral position. This design effectively improves poor posture such as rounded shoulders and hunchback, enhancing the corrective effect. The proportionate design makes the posture corrector more stable during wear, effectively resisting external interference. By rationally distributing the mechanical support points, the posture corrector's structure is more stable, reducing the decrease in corrective effect caused by slippage or displacement. It can adapt to users of different body types, especially teenagers and adults, meeting the needs of different heights and body types. Users can also fine-tune it according to their own needs and comfort for better wearing results. When the proportion is less than 1 / 3, the second connection point Z of the posture corrector is too close to the first connection point X, causing concentrated pressure on the back of the shoulder strap 200, which can easily increase the feeling of pressure in the shoulders and armpits. Because the second connection point Z is too close to the first connection point X, the mechanical support structure of the posture corrector is not stable enough, failing to effectively guide the shoulder and back muscles to exert force in the correct direction, thus reducing the corrective effect. Excessive local pressure can cause significant discomfort to the wearer during prolonged use, affecting the wearing experience of the posture corrector. When the ratio is greater than 2 / 3, the second connection point Z is too far away from the first connection point X, and the mechanical support structure of the posture correction belt becomes loose and cannot provide sufficient support. The excessive distance causes the posture correction belt to easily slide or shift during wearing, making it unable to maintain a stable support state, thereby reducing the correction effect. The excessive distance may not be suitable for users with smaller body sizes, resulting in a reduction in the universality of the posture correction belt.

[0037] like Figure 1 and Figure 2As shown, in this embodiment, the distance between the first connection point X of the first shoulder strap 200 and the first connection point X of the second shoulder strap 200 is 39 cm-45 cm. When the distance between the first connection point X of the two shoulder straps 200 is 39cm-45cm, the posture corrector can more reasonably distribute the pressure on the shoulders and back, making the pressure distribution of the shoulder straps 200 on the shoulders more even, reducing discomfort caused by excessive local pressure, and thus significantly improving wearing comfort. Within this distance range, the structure of the posture corrector can better guide the muscles of the shoulders and back to exert force in the correct direction, helping the body return to a neutral position, effectively improving poor posture such as hunchback and improving the correction effect. The design within this distance range makes the posture corrector more stable during wearing, effectively resisting external interference. By reasonably distributing the mechanical support points, the structure of the posture corrector is more stable, reducing the decrease in correction effect caused by slippage or displacement. This distance design can adapt to users of different body types, especially teenagers and adults, meeting the needs of different heights and body types. At the same time, users can make fine adjustments according to their own needs and comfort to achieve better wearing results. When the distance between the first connection points X of the two shoulder straps 200 is less than 39cm, the pressure of the shoulder straps 200 is concentrated on the shoulders, which can easily lead to increased pressure in the shoulders and underarms. Because the distance between the shoulder straps 200 is too small, the mechanical support structure of the posture corrector is not stable enough, and it cannot effectively guide the muscles of the shoulders and back to exert force in the correct direction, thus reducing the corrective effect. Excessive local pressure can cause significant discomfort for the wearer during prolonged use, affecting the wearing experience. When the distance between the first connection points X of the two shoulder straps 200 is greater than 45cm, the mechanical support structure of the posture corrector becomes loose and cannot provide sufficient support. The excessive distance causes the posture corrector to easily slip or shift during wear, making it difficult to maintain a stable support state, thus reducing the corrective effect. An excessively long distance may not be suitable for users with smaller body sizes, reducing the universality of the posture corrector.

[0038] like Figure 1 , Figure 2 and Figure 3As shown, in this embodiment, the width of the middle section of the shoulder strap 200 is greater than the width of both ends. The middle section of the shoulder strap 200 is the part that bears the main tensile and support forces. By increasing the width of the middle section, the mechanical support capacity of the shoulder strap 200 can be significantly enhanced, enabling it to better withstand and distribute pressure from the body. A wider middle section can distribute pressure more evenly, avoiding localized pressure caused by concentrated pressure, effectively reducing discomfort in the shoulders and back, and improving wearing comfort. A wider middle section can better conform to the natural curves of the human shoulder and back, reducing localized pressure caused by a narrow shoulder strap 200. By optimizing the width distribution of the shoulder strap 200, the posture corrector can fit the body more closely when worn, reducing slippage and shifting, thereby improving wearing comfort. A wider middle section can provide a more stable support structure, ensuring that the corrective force can be effectively transmitted to the shoulders and back. This posture corrector helps the body return to a neutral position, significantly improving poor posture such as rounded shoulders and hunchback. By optimizing the width distribution of the shoulder straps (200mm), it corrects the body in multiple dimensions, effectively adjusting not only shoulder tilt but also back curvature. The wider middle section disperses stress concentration points, reducing material fatigue and damage caused by excessive localized stress, thus extending the lifespan of the posture corrector. The optimized shoulder strap width distribution also makes the posture corrector more stable during wear, effectively resisting external interference and improving product durability. The wider middle section can be better concealed under clothing, reducing the exposed portion of the posture corrector and enhancing its aesthetics. This design not only improves the product's functionality and comfort but also considers aesthetics, meeting the personalized needs of different users.

[0039] like Figure 1 , Figure 2 and Figure 3As shown, in this embodiment, the width of the middle section of the shoulder strap 200 is 6 cm to 7 cm; and / or the width of the front end and the rear end of the shoulder strap 200 are 4.5 cm to 5 cm. When the width of the middle section is 6 cm to 7 cm, it can provide stable mechanical support, while evenly distributing pressure, reducing discomfort in the shoulders and back; it can better conform to the natural curves of the human shoulder and back, reducing slippage and displacement, and improving wearing comfort; it can provide a more stable support structure, ensuring that the corrective force can be effectively transmitted to the shoulders and back, helping the body return to a neutral position, significantly improving poor posture such as hunchback and rounded shoulders; it can disperse stress concentration points, reducing material fatigue and damage caused by excessive local stress, thereby extending the service life of the posture corrector. When the width of the front and back ends is 4.5cm to 5cm, it ensures adequate mechanical support for the shoulder straps 200 at both ends, while reducing pressure on the shoulders and underarms. This reduces localized pressure on the shoulders and underarms, improving wearing comfort. It also ensures adequate mechanical support for the shoulder straps 200 at both ends, thus more effectively guiding the shoulder and back muscles to exert force in the correct direction. Furthermore, it ensures adequate mechanical support for the shoulder straps 200 at both ends, reducing localized pressure on the shoulders and underarms, and improving product durability. When the width of the middle section is less than 6cm, it may result in insufficient mechanical support, while a width greater than 7cm may lead to excessive localized pressure, increasing the feeling of pressure. A middle section width exceeding the 6cm-7cm range may also lead to uneven distribution of corrective force, thus reducing the corrective effect. Similarly, a width of less than 4.5cm at the front and back ends may result in insufficient mechanical support, while a width greater than 5cm may increase localized pressure on the shoulders and underarms. A width exceeding the 4.5cm-5cm range at the front and back ends may reduce wearing comfort, affecting the wearing experience of the posture corrector.

[0040] like Figure 1 , Figure 2 and Figure 3As shown, in this embodiment, the waist belt 100 includes a back piece 101 and a hook and loop fastener portion 102. The hook side and the loop side of the hook and loop fastener portion 102 are located at opposite ends of the back piece 101. The width of the back piece 101 is greater than the width of the hook and loop fastener portion 102. The width of the back piece 101 is 8 cm to 12 cm, and / or the width of the hook and loop fastener portion 102 is 5 cm to 7 cm. The greater width of the back piece 101 than the hook and loop fastener portion 102 allows the back piece 101 to better conform to the natural curve of the human waist, reducing slippage and shifting, and improving wearing comfort. The moderate width of the hook and loop fastener ensures that it will not cause excessive pressure on the skin when fastened, while providing sufficient adhesive force to ensure that the waist belt 100 will not loosen during use. When the width of the back piece 101 is 8cm to 12cm, it provides stable mechanical support, effectively distributing pressure on the waist, reducing localized pressure, and thus improving wearing comfort. It ensures sufficient adhesive force for the Velcro when fastened, while avoiding localized pressure caused by excessively wide Velcro. A wider back piece 101 disperses stress concentration points, reducing material fatigue and damage caused by excessive localized stress, thereby extending the lifespan of the posture corrector. A moderate width of the back piece 101 ensures the posture corrector doesn't appear too bulky when worn and can be better concealed under clothing, enhancing its aesthetics. When the width of the Velcro section 102 is 5cm to 7cm, the moderate Velcro width ensures that the hook and loop sides of the Velcro will not lose adhesive force due to excessive stretching or wear during repeated use and application. The moderate Velcro width also ensures it doesn't appear too obtrusive when worn, reducing excess material exposure and improving overall aesthetics. If the width of the back piece 101 is less than 8cm, it may result in insufficient mechanical support, while a width greater than 12cm may lead to excessive local pressure and increased discomfort. If the width of the back piece 101 exceeds the range of 8cm to 12cm, it may result in uneven distribution of corrective force, thereby reducing the corrective effect. If the width of the Velcro is less than 5cm, it may result in insufficient adhesion, while a width greater than 7cm may lead to increased local pressure on the waist. If the width of the Velcro exceeds the range of 5cm to 7cm, it may reduce wearing comfort and affect the wearing experience of the posture corrector.

[0041] When implementing, such as Figure 1-4 As shown, a posture corrector belt is provided, including a waist belt 100 and a shoulder strap 200. The waist belt 100 is provided with a second limiting strap 400. The first end of the shoulder strap 200 is connected to the waist belt 100, and the end of the shoulder strap 200 passes through the second limiting strap 400 and overlaps with the Velcro portion 102 at the other end of the waist belt 100.

[0042] The shoulder strap 200 is provided with a first limiting strap 300, and the left shoulder strap, right shoulder strap and first limiting strap 300 are overlapped and connected to the back.

[0043] Armhole Space: The first connection point X between the shoulder strap 200 and the waist belt 100 is located at the junction of the serratus anterior and pectoralis major muscles. The second connection point Z between the shoulder strap 200 and the waist belt 100 is located at the latissimus dorsi muscle. The shoulder strap 200 extends upward from the first connection point X to the apex Y. The shoulder strap 200 extends diagonally downward from the apex Y to the intersection point W. The first connection point X extends diagonally downward to the second connection point Z. The first connection point X, the second connection point Z, the intersection point W, and the shoulder strap apex Y are connected sequentially to form the armhole space A. The straight-line distance between the apex Y and the second connection point Z of the shoulder strap 200 is 20 cm to 24 cm. The straight-line distance h from the first connection point X to the second connection point Z is 1 / 3 to 2 / 3 of the straight-line distance g from the first connection point X to the apex Y. The curvature r of the shoulder strap 200 at the first connection point X is 95-110 degrees.

[0044] By moving the first connection point X forward to its position, which corresponds to the position of the serratus anterior muscle in the human body, increasing the straight-line distance between the apex Y of the shoulder strap 200 and the second connection point Z, and increasing the curvature at the first connection point X of the shoulder strap 200, the area of ​​the armhole space A is expanded, the force on the ribs is reduced, and the discomfort of the armpit is resolved.

[0045] like Figure 4-6 The posture correction belt of this utility model has an open cross structure and is adjustable:

[0046] Armhole space A: such as Figure 5As shown, the front end E1 and the end E2 of the shoulder strap 200 can be freely stretched to form the armhole space B1. The space B1 determines the comfort of the shoulder and underarm. Because this design allows for free adjustment here, and the shoulder strap connection points A4 / B4 are moved forward, the spaces B1 and B2 are enlarged, avoiding the common problem of "squeezing under the armpit and shoulder" in products on the market. The connection point between the shoulder strap 200 and the lower chest of this posture corrector is located at the position corresponding to the serratus anterior and pectoralis major muscles of the human body, close to the front of the chest. Compared with the existing solutions, the connection point of the existing solutions is located in the underarm part of the human body, which causes discomfort under the armpit. The distance between the shoulder strap connection points A4 and B4 of this posture corrector is 39 cm-45 cm, which is longer than the existing technology. By moving the connection points A4 / B4 of the shoulder strap 200 and the waist belt 100 forward, when the shoulder strap 200 exerts its shaping force, the direction of the force is upward through the shoulder and diagonally downward to the lower chest. By using the shoulder as an effective support point for shaping, the contact area between the shoulder strap 200 and the serratus anterior and pectoralis major muscles is reduced, resulting in less friction and less force on the ribs, thus resolving underarm discomfort. When the binding force is applied to the serratus anterior and pectoralis major muscles, the discomfort of "pulling under the armpit" is reduced. The distance from the highest point Y (highest point of the shoulder strap) to the lowest point Z (above the limiting strap) of the armhole portion of this posture corrector belt is within the range of 20cm-24cm, and the inward curvature of its intersection point (first connection point X) is within the range of 95-110 degrees. This distance and curvature ensure that the armhole portion does not constrict the underarm while maintaining the binding force of the shoulder strap 200 on the shoulder and back.

[0047] This utility model posture corrector belt widens the distance between the shoulder strap connection points (A4 to B4) at both ends to 39cm-45cm. After wearing, the shoulder strap connection points move forward, increasing the space in the armhole. Furthermore, this design uses an open cross-shaped shoulder strap design, so when the shoulder straps are stretched at 200°, there will be no problem of "pulling under the armpit".

[0048] Shoulder strap width: Starting from the front shoulder, E1 crosses symmetrically across the back, passes through A1, and can be freely stretched to a suitable length, fastening at the lower bust D1 (the same applies to the symmetrical part of E2). Through the elastic stretch of the fabric, the force of the shoulders and back forms a stable triangular support, helping to correct poor posture and gradually form correct posture habits. Simultaneously, the width of the middle section of shoulder strap E1 is widened to 7.5cm, and the width of both ends is 4.5cm-5cm, increasing the contact area with the back in the middle section for greater support and a gentler shaping effect. The ends gradually narrow to 4.5cm-5cm, and the connecting surface width at the front of the armholes (A4 / B4) is designed to be 4.5cm, meeting the requirements for shaping strength while reducing restriction on the arms, allowing for greater range of motion and freedom of movement. Furthermore, the open structure at the ends allows for free adjustment according to individual needs, greatly improving product comfort and individual adaptability.

[0049] Waistband 100 height: F1 Velcro hooks are fastened to the appropriate position on D2 Velcro loops to form the overall body circumference. G1 is the back piece 101 (located at the back), and D1 and D2 are the front pieces (located at the chest, under the chest). G1 is 10cm high, and D1 / D2 are 6cm high, both significantly smaller than existing technologies. This reduction in overall body circumference height reduces restriction on the torso, allowing for greater freedom of movement. Simultaneously, the front pieces D1 / D2 are 4cm shorter than the back piece G1. The increased height of the G1 back piece, combined with the E1 / E2 cross structure, creates a flat support plane on the back. The increased design increases the contact area with the back, providing stronger support. When the lateral circumference shaping force interacts with the shoulder shaping force, the force is more gentle and comfortable. Meanwhile, the front panels D1 / D2 are located at the lower bust, and this area is designed to be 6cm in size to accommodate the fabric's shape during shaping. Furthermore, a smaller area covering the waist results in less constriction and greater breathability and comfort. This new posture corrector is designed for an open and upright posture, not targeting the waist and abdomen. It only covers the lower bust and back, and the tightness is freely adjustable, preventing stuffiness and restricted movement.

[0050] like Figure 6 As shown, the C1 cross structure positioning design is used. Compared with existing technologies, this novel posture corrector belt has an extended C1 cross structure, which can better adapt to different individuals and meet more stretching and adjustment needs. A3 / A4 connect, with C3 passing through the F4 limiting piece and fastening to D4. The symmetrical parts B3 / B4 connect, with C4 passing through the F3 limiting piece and fastening to D3. The limiting design of A1 / A2 ensures that the shoulder straps E1 / E2 connect from the apex to A1 / A2, with the force point at the shoulder, providing a restraining effect on the scapula and maintaining balance in the shoulder and back, thereby achieving the purpose of posture correction.
