Description

Technical Field

[0001] This utility model relates to the field of human health care mechanical products, and more specifically, to a corrective back strap. Background Technology

[0002] Posture correctors, as a product designed to assist in correcting posture, primarily help users improve and maintain correct sitting and standing postures. Through scientific design and appropriate material selection, posture correctors effectively support the back and waist, reducing the burden on the spine and thus preventing and alleviating problems such as scoliosis and hunchback caused by prolonged poor posture. Furthermore, posture correctors can also promote blood circulation to some extent, relieve muscle fatigue, and improve overall physical comfort. Long-term use of posture correctors can not only correct poor posture but also cultivate good posture habits, which is particularly beneficial for the growth and development of adolescents.

[0003] Existing corrective braces typically use support plates or straps to apply tension to the spine or back, forcing it to remain upright. However, prolonged wear of these straps or support plates can lead to back pain and discomfort due to the lack of support and the resulting immense pressure on the back. Summary of the Invention

[0004] To address the problem of discomfort caused by prolonged wear of corrective straps in existing technologies, this solution proposes a corrective strap that overcomes the shortcomings of existing technologies through the coordinated use of a base, side seats, and push pin plates.

[0005] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0006] A corrective harness, including

[0007] A waist belt, which is used to secure the body to the human body, has a vertical strip of cloth extending along the direction of the human spine;

[0008] The second elastic element is fixed on the vertical fabric strip and has a second curved portion protruding towards the back of the human body. The second curved portion supports the human body and dynamically deforms as the back of the human body bends, adaptively adjusting the support force applied to the back of the human body.

[0009] This application achieves dynamic support for the human spine through the synergistic effect of the vertical fabric straps of the waist belt and the second elastic element. The curved part of the second elastic element is made of a high-resilience material, which can generate a counterforce when the body leans forward, effectively relieving pressure on the lumbar spine. When the user bends over, the second elastic element automatically adjusts its curvature to follow the back's curve, providing progressive support and avoiding the stiffness and constriction of traditional lumbar supports. This intelligent adjustment mechanism is particularly suitable for people who need to maintain a sitting posture or bend over for long periods of time, providing sufficient lumbar support while ensuring flexibility of movement.

[0010] In a corrective back brace provided in this application, the second elastic member further includes a straight section, one end of which is fixedly connected to one end of the second curved section. The straight section extends along the natural curve of the waist, forming a continuous support structure with the second curved section. This design effectively disperses lumbar pressure, maintaining spinal stability while avoiding the discomfort caused by traditional rigid supports, significantly improving comfort during prolonged wear.

[0011] In a corrective back brace provided in this application, a second elastic band is further fixed to the concave surface of the second curved portion. The second elastic band is used to adjust the elastic strength of the second curved portion. The second elastic band is connected to one side of the concave surface of the second curved portion for precisely adjusting the support force of the two elastic elements. The length of this second elastic band can be adjusted according to the user's body shape and correction needs. By changing the preload, the initial curvature of the arc-shaped second elastic plate can be adjusted, allowing the product to be personalized to fit the spinal curves of different users, ensuring sufficient support strength while avoiding excessive compression. When the user moves, the second elastic band and the second elastic plate work together to form a progressive dynamic support system, significantly improving the correction effect and wearing comfort.

[0012] In a corrective back brace provided in this application, the second elastic element further includes two elastic strips, which are fixed parallel to each other on the vertically placed fabric strip. The parallel fixing of the two elastic strips allows them to be fixed to one side of the spine, forming a symmetrical support structure that evenly distributes lumbar pressure and provides balanced elastic feedback during activity, avoiding corrective deviations caused by uneven force on one side.

[0013] In a corrective support belt provided in this application, the waistband further includes a horizontal fabric strap that wraps around the waist of the human body, and the horizontal fabric strap is perpendicularly connected to the vertical fabric strap. The horizontal fabric strap can be fixed to the waist of the human body, making the corrective support belt more secure and comfortable to wear.

[0014] In a corrective harness provided in this application, further including...

[0015] The shoulder strap has a first loop and a second loop, the first loop and the second loop are spaced apart and can be wrapped around and fastened to the shoulders on both sides of the human body.

[0016] The first elastic element, connected between the first and second loop straps, supports the human body and dynamically deforms as the shoulders contract or relax, adaptively adjusting the support force applied to the body. The corrective back strap uses a split double-loop structure to fix the shoulders on both sides of the body, and together with the first elastic element, it supports the body between the shoulders. The first elastic element can dynamically conform to the curve of the human shoulder, achieving adaptive support. When the user moves, the first elastic element will deform at different degrees according to the width of the shoulders, thereby adjusting the support force in real time, providing stable support while maintaining flexible movement space. The first elastic element also has a cushioning and shock absorption function, which can effectively absorb the impact of movement. Its ergonomic design is particularly suitable for scenarios such as sports protection and medical rehabilitation that require both support and flexibility, not only significantly improving wearing comfort but also reducing fatigue from long-term use, allowing users to move more freely and safely.

[0017] In a corrective back brace provided in this application, the first elastic element is further wherein its two ends are respectively connected to the first loop and the second loop on the side closer to the back of the human body. The first elastic element being connected to the side closer to the back of the human body allows it to better conform to the movement trajectory of the scapular region. When the user performs forward or backward shoulder movements, the first elastic element can generate a more ergonomic bidirectional stretching force, which neither excessively restricts the range of motion of the shoulder joint nor fails to provide precise mechanical feedback.

[0018] In a corrective carrying strap provided in this application, the support point of the first elastic element is further located at the spine between the shoulders. The location of the first elastic element support point at the spine optimizes force transmission by utilizing the stability of the midline spinal position. Furthermore, it can transmit support force through the skeletal system, reducing soft tissue compression and improving comfort. Simultaneously, it maintains the mechanical balance of the carrying strap, ensuring that the corrective force is continuously and stably applied to the target area.

[0019] In a corrective back brace provided in this application, the first elastic element is further defined as an arc-shaped elastic plate, which has a first curved portion protruding towards the human body. The arc-shaped elastic plate design of the first elastic element allows its first curved portion to perfectly conform to the concave curve between the shoulders, increasing the contact area with the body, reducing the pressure of the first elastic plate on the body, and improving wearing comfort. Furthermore, this arc-shaped structure provides stable support while automatically adjusting the curvature according to the user's back movements, achieving dynamic adaptation. When the user performs forward or backward bending movements, the curved portion of the elastic plate generates progressive elastic feedback, ensuring the continuity of the corrective force without restricting the normal range of motion, significantly improving wearing comfort and corrective effect.

[0020] In a corrective shoulder strap provided in this application, the arc-shaped elastic plate further includes connecting portions fixed to both ends of the first curved portion, with the connecting portions at both ends located on the same plane, and the shoulder strap connected to the connecting portions. The symmetrical design, where the connecting portions at both ends of the arc-shaped elastic plate are on the same plane, ensures a balanced distribution of force. The fixing structure between the connecting portions and the shoulder straps allows the deformation force of the arc-shaped elastic plate to be evenly transmitted to both shoulders, avoiding excessive force on one side.

[0021] In a corrective back brace provided in this application, a first elastic band is further connected to the concave side of the first curved portion to adjust the elasticity of the first elastic element. The first elastic band, connected to the concave side of the first curved portion, is used to precisely adjust the support strength of the first elastic element. This first elastic band can be adjusted in length according to the user's body shape and correction needs, and the initial curvature of the arc-shaped first elastic plate can be adjusted by changing the preload. This design allows the product to be personalized to fit the spinal curves of different users, ensuring sufficient support strength while avoiding excessive compression. When the user moves, the first elastic band and the first elastic plate work together to form a progressive dynamic support system, significantly improving the correction effect and wearing comfort.

[0022] In a corrective support belt provided in this application, the number of first elastic bands is no less than two, and both are detachably connected to the first elastic element or the length of the first elastic bands is adjustable. The first elastic bands adopt a detachable design with no less than two bands, and the length of each elastic band can be independently adjusted. This structure allows users to flexibly configure the number and tightness of the elastic bands according to actual support needs, achieving precise force adjustment and facilitating maintenance and replacement. By adjusting the length of the elastic bands, the initial preload and deformation range of the first elastic element can be precisely controlled, enabling the product to adapt to different usage scenarios from mild posture correction to high-intensity support, significantly improving the product's functional expandability and usage flexibility.

[0023] In a corrective back strap provided in this application, one end of the second curved portion is connected to the first elastic member, and the second elastic member is perpendicular to the first elastic member. The second elastic member and the first elastic member are arranged in a perpendicular cross layout, extending along the direction of the spine to form a longitudinal support system. This composite elastic structure provides longitudinal stability of the spine while correcting shoulder posture laterally through bidirectional mechanical synergy. The extended design of the second elastic member can effectively distribute back pressure, and when the user performs bending or stretching movements, it can generate a progressive rebound force that conforms to the physiological curve of the spine, avoiding the discomfort caused by rigid support while maintaining a good posture correction effect. The second elastic member can significantly improve the three-dimensional support performance of the back strap, making the corrective force distribution more in line with human biomechanical characteristics.

[0024] In a corrective back strap provided in this application, the corrective back strap further includes a tension component, which has a first strap and a second strap. One end of the first strap and the second strap is fixed at the junction of the horizontal and vertical fabric strips. The other ends of the first strap and the second strap are respectively wrapped around and fixed to the shoulder strap, and the tightness of the first strap and the second strap is adjusted by buckles connected to the shoulder strap. Fixing one end of the first strap and the second strap at the junction of the horizontal and vertical fabric strips optimizes the force transmission path, so that the force exerted by the shoulder on the first strap and the second strap is concentrated at the junction of the horizontal and vertical fabric strips. This junction is located in a concave area at the spine, reducing the contact between the horizontal fabric strip and the body, reducing friction between them, and improving wearing comfort. Furthermore, the triangular structure formed by the first strap and the second strap directs the force towards the direction of spinal extension, so that the corrective force is evenly distributed to the shoulder strap and waist, avoiding local stress concentration.

[0025] The beneficial effects of this application are:

[0026] This application achieves dynamic support for the human spine through the synergistic effect of the vertical fabric straps of the waist belt and the second elastic element. The curved part of the second elastic element is made of a high-resilience material, which can generate a counterforce when the body leans forward, effectively relieving pressure on the lumbar spine. When the user bends over, the second elastic element automatically adjusts its curvature to follow the back's curve, providing progressive support and avoiding the stiffness and constriction of traditional lumbar supports. This intelligent adjustment mechanism is particularly suitable for people who need to maintain a sitting posture or bend over for long periods of time, providing sufficient lumbar support while ensuring flexibility of movement.

[0041] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings and embodiments. Example 1

[0042] like Figure 1-2 As shown, a corrective harness includes a waist belt 200 and a second elastic element 100.

[0043] The waist belt 200 is used to secure itself to the human body and has a vertical fabric strap 220 extending along the spine. A second elastic element 100 is fixed to the vertical fabric strap 220 and has a second curved portion 110 protruding towards the back. The second curved portion 110 supports the body and dynamically deforms with the back, adaptively adjusting the support force applied to the back. Through the synergistic action of the vertical fabric strap 220 and the second elastic element 100, dynamic support for the spine is achieved. The curved portion of the second elastic element 100 is made of a high-resilience material, generating a counterforce when the body leans forward, effectively relieving lumbar pressure. When the user bends over, the second elastic element 100 automatically adjusts its curvature to follow the back curve, providing progressive support and avoiding the stiffness and constriction of traditional lumbar supports. This intelligent adjustment mechanism is particularly suitable for people who need to maintain a seated posture or bend over for extended periods, providing sufficient lumbar support while ensuring flexibility of movement.

[0044] like Figure 2-3As shown, the second elastic element 100 includes a straight section 120 and a second curved section 110. One end of the straight section 120 is fixedly connected to one end of the second curved section 110. The straight section 120 extends along the natural curve of the waist, forming a continuous support structure with the second curved section 110. This design effectively disperses lumbar pressure, maintaining spinal stability while avoiding the discomfort caused by traditional rigid supports, significantly improving comfort during long-term wear. A second elastic band 130 is fixed to the concave surface of the second curved section 110, and the second elastic band 130 is used to adjust the elastic strength of the second curved section 110. The second elastic band 130 is connected to one side of the concave surface of the second curved section 110 for precisely adjusting the support strength of the two elastic elements. The length of the second elastic band 130 can be adjusted according to the user's body shape and correction needs. By changing the preload, the initial curvature of the arc-shaped second elastic plate can be adjusted, allowing the product to be personalized to fit the spinal curves of different users, ensuring sufficient support strength while avoiding excessive compression. When the user moves, the second elastic band 130 works in conjunction with the second elastic plate to form a progressive dynamic support system, which significantly improves the corrective effect and wearing comfort.

[0045] like Figure 2 As shown, the second elastic element 100 includes two elastic strips 140, which are fixed in parallel to the vertical fabric strip 220. The parallel fixing of the two elastic strips 140 allows them to be fixed to one side of the spine respectively, forming a symmetrical support structure that can evenly distribute the pressure on the lower back and provide balanced elastic feedback during activity, avoiding correction deviation caused by uneven force on one side.

[0046] like Figure 2 As shown, the waist belt 200 includes a horizontal fabric strap 210 that wraps around the waist of the human body, and the horizontal fabric strap 210 is vertically connected to the vertical fabric strap 220. The horizontal fabric strap 210 can be fixed to the waist of the human body, making the corrective back strap more stable and comfortable to wear. Example 2

[0047] like Figure 4As shown, the corrective back strap provided in this application includes shoulder straps 300100 and a first elastic element 400. The shoulder straps 300100 have a first loop 310 and a second loop 320, which are spaced apart and can be wrapped around and fastened to the shoulders on both sides of the body. The first elastic element 400 is connected between the first loop 310 and the second loop 320, supporting the body and dynamically deforming as the shoulders contract or relax, adaptively adjusting the support force applied to the body. The corrective back strap uses a split double-loop structure to fix the shoulders on both sides of the body, and the first elastic element 400 supports the body between the shoulders. The first elastic element 400 can dynamically conform to the curve of the shoulders, achieving adaptive support. When the user moves, the first elastic element 400 deforms to different degrees according to the width of the shoulders, thereby adjusting the support force in real time, providing stable support while maintaining flexible movement space. The first elastic element 400 also features cushioning and shock absorption, effectively absorbing the impact of movement. Its ergonomic design is particularly suitable for scenarios requiring both support and flexibility, such as sports protection and medical rehabilitation. It not only significantly improves wearing comfort but also reduces fatigue from prolonged use, allowing users to move more freely and safely.

[0048] like Figure 1 As shown, the first elastic element 400 is connected at both ends to the first loop 310 and the second loop 320 on the side closer to the back of the human body. The first elastic element 400 is connected to the side closer to the back of the human body, which can better conform to the movement trajectory of the human scapular region. When the user performs shoulder extension or retraction movements, the first elastic element 400 can generate a more ergonomic bidirectional stretching force, which will not excessively restrict the range of motion of the shoulder joint, but will also provide precise mechanical feedback.

[0049] The support point 410 of the first elastic element 400 is located at the spine between the shoulders. This location allows for optimized force transmission by utilizing the midline spinal stability. Furthermore, it transmits support force through the skeletal system, reducing soft tissue compression and improving comfort. Simultaneously, it maintains the mechanical balance of the straps, ensuring a continuous and stable application of corrective force to the target area.

[0050] like Figure 5As shown, the first elastic element 400 is an arc-shaped elastic plate 430, which has a first curved portion 431 protruding towards the human body. The arc-shaped elastic plate 430 design of the first elastic element 400 allows its first curved portion 431 to perfectly conform to the concave curve between the shoulders, increasing the contact area with the body, reducing the pressure of the first elastic plate on the body, and improving wearing comfort. Furthermore, this arc-shaped structure provides stable support while automatically adjusting the curvature according to the user's back movements, achieving dynamic adaptation. When the user performs forward or backward bending movements, the curved portion of the elastic plate generates progressive elastic feedback, ensuring the continuity of the corrective force without restricting the normal range of motion, significantly improving wearing comfort and corrective effect.

[0051] like Figure 5 As shown, the arc-shaped elastic plate 430 includes connecting portions 432 fixed to both ends of the first curved portion 431. The connecting portions 432 at both ends are located on the same plane, and shoulder straps 300100 are connected to the connecting portions 432. The symmetrical design of the connecting portions 432 at both ends of the arc-shaped elastic plate 430 ensures the balance of force distribution. The fixing structure of the connecting portions 432 and the shoulder straps 300100 allows the deformation force of the arc-shaped elastic plate 430 to be evenly transmitted to both shoulders, avoiding the problem of excessive force on one side. A first elastic band 420 for adjusting the elasticity of the first elastic element 400 is connected to the concave side of the first curved portion 431. The first elastic band 420 is used to precisely adjust the support force of the first elastic element 400. The length of the first elastic band 420 can be adjusted according to the user's body shape and correction needs, and the initial curvature of the arc-shaped first elastic plate can be adjusted by changing the preload. This design allows the product to be personalized to fit the spinal curves of different users, ensuring sufficient support strength while avoiding excessive compression. When the user moves, the first elastic band 420 works in conjunction with the first elastic plate to form a progressive dynamic support system, significantly improving the corrective effect and wearing comfort.

[0052] like Figure 5 As shown, there are at least two first elastic bands 420, both of which are detachably connected to the first elastic element 400, or the length of the first elastic band 420 is adjustable. The first elastic bands 420 employ a detachable design with at least two bands, each with independently adjustable length. This structure allows users to flexibly configure the number and tension of the elastic bands according to actual support needs, enabling precise force adjustment and facilitating maintenance and replacement. By adjusting the length of the elastic bands, the initial preload and deformation range of the first elastic element 400 can be precisely controlled, allowing the product to adapt to different usage scenarios, from mild posture correction to high-intensity support, significantly improving the product's functional expandability and usage flexibility.

[0053] like Figure 1As shown, one end of the second curved portion 110 is connected to the first elastic element 400, and the second elastic element 100 is perpendicular to the first elastic element 400. The second elastic element 100 and the first elastic element 400 are arranged in a vertically intersecting layout, extending along the direction of the spine to form a longitudinal support system. This composite elastic structure provides longitudinal stability of the spine while correcting shoulder posture laterally through bidirectional mechanical synergy. The extended design of the second elastic element 100 can effectively distribute back pressure. When the user performs bending or stretching movements, it can generate a progressive rebound force that conforms to the physiological curve of the spine, avoiding the discomfort caused by rigid support while maintaining a good posture correction effect. The second elastic element 100 can significantly improve the three-dimensional support performance of the strap, making the distribution of corrective force more in line with human biomechanical characteristics. Example 3

[0054] like Figure 6 As shown, the corrective back strap includes a tension component 500, which has a first strap 510 and a second strap 520. One end of the first strap 510 and the second strap 520 is fixed at the junction of the horizontal cloth strip 210 and the vertical cloth strip 220. The other ends of the first strap 510 and the second strap 520 are respectively wrapped around and fixed to the shoulder strap 300100, and the tightness of the first strap 510 and the second strap 520 is adjusted by the buckle 330130 connected to the shoulder strap 300100. The first strap 510 and the second strap 520 are fixed at one end at the junction of the horizontal cloth strap 210 and the vertical cloth strap 220, which optimizes the force transmission path. This concentrates the tension on the shoulder from the first strap 510 and the second strap 520 at the junction of the horizontal cloth strap 210 and the vertical cloth strap 220. This junction is located in a concave area along the spine, reducing contact between the horizontal cloth strap 210 and the body, decreasing friction, and improving wearing comfort. Furthermore, the triangular structure formed by the first strap 510 and the second strap 520 directs the tension towards the direction of spinal extension, evenly distributing the corrective force to the shoulder straps 300-100 and the waist, avoiding localized stress concentration.

[0055] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the figures shown are only one embodiment of the present invention; the actual structure is not limited to this. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
