Description

Back support and posture corrector Technical Field

[0001] This utility model relates to the field of orthodontic devices, and in particular, to a back support. Furthermore, this utility model also relates to a posture corrector belt including the aforementioned back support. Background Technology

[0002] Existing posture correction belts generally use a back support structure to achieve posture correction. Traditional solutions often employ longitudinally arranged herringbone strips or a single-sided plastic memory board as the main support structure. For example, Chinese patent CN221814347U discloses a "seamless posture correction belt" that uses a grooved support plate as back support. While this type of structure applies single-point or linear support to the back using rigid materials and can achieve basic posture reminders, it suffers from the following technical drawbacks in practical use:

[0003] 1. Fishbone strips or single-sided memory boards can only provide unidirectional support. When the human body makes a large-angle forward lean or side bend, the support structure is prone to stress concentration, which leads to deformation failure and cannot maintain effective corrective torque.

[0004] 2. Commercially available products are generally limited by the rigid connection of existing support components, and cannot extend downward to form a wrapping support for the 4th and 5th lumbar vertebrae. The lack of support structure covering the lower lumbar vertebrae will cause an imbalance in the distribution of spinal load, leading to increased lumbar lordosis, which may even induce abnormal pressure on the intervertebral discs.

[0005] 3. The existing support structure cannot anatomically adapt to the human back muscle groups (especially the serratus posterior inferior and erector spinae muscles). During use, it will cause abnormal compensatory contraction of the erector spinae muscles, and long-term wear can easily lead to muscle fatigue or even strain. Summary of the Invention

[0006] This invention provides a back support and posture correction belt with a pair of wing-shaped support plates. The belt covers the lower middle erector spinae muscles, and its wing-shaped design conforms to the natural curvature of the lumbar spine, fitting the waistline. It provides necessary support to the serratus posterior and erector spinae muscles, reducing muscle burden and supporting and fixing the spine without restricting movement in other directions. This achieves a combined effect of external force support and self-exercise, thus providing support and fixation. It also prevents long-term continuous fixation from causing disuse atrophy of the lumbar muscles, decreased muscle strength, and spinal joint stiffness. This invention addresses the technical problems of existing posture correction belts, such as insufficient support strength, inadequate lumbar spine coverage, and poor biomechanical adaptability.

[0007] According to one aspect of the present invention, a back support is provided, comprising: a fabric layer and wing-shaped support plates. The fabric layer is used to conform to the human body to increase comfort. Two sets of wing-shaped support plates are provided, which are symmetrically attached to the fabric layer. The wing-shaped support plates are used to conform to and support the serratus posterior inferior muscle and the middle and lower erector spinae muscles on the corresponding sides. The two sets of wing-shaped support plates work together to support the spine from both sides and limit the spine.

[0008] Furthermore, the wing-shaped support plate includes a first plate portion and a second plate portion arranged sequentially from bottom to top. The first plate portion is used to be arranged along and adhere to the middle and lower erector spinae muscles. The second plate portion is used to be arranged at an angle with its free end facing the direction of the lower serratus posterior muscle and simultaneously adhere to the middle and lower erector spinae muscles and the lower serratus posterior muscle. An inflection point G is formed between the first plate portion and the second plate portion.

[0009] Furthermore, the included angle between the first plate portion and the second plate portion is 160° to 170°.

[0010] Furthermore, the maximum spacing between the two sets of airfoil support plates is 10cm to 14cm; and / or the minimum spacing between the two sets of airfoil support plates is 3cm to 5cm.

[0011] Furthermore, the length dimension of the airfoil support plate is 15cm to 18cm; and / or the width dimension of the airfoil support plate is 4cm to 6cm.

[0012] Furthermore, the airfoil support plate is made of PE soft plastic sheet with a thickness of 0.1cm to 0.4cm.

[0013] Furthermore, the back support also includes soft plastic support strips. Two sets of soft plastic support strips are symmetrically attached to the fabric layer, and the two sets of soft plastic support strips are located on the outer side of the corresponding airfoil support plate. The soft plastic support strips and the airfoil support plate are arranged at intervals.

[0014] Furthermore, the soft plastic support strips and wing-shaped support plates together form a lateral support width of 330mm to 380mm for the lower back.

[0015] Furthermore, the soft plastic support strips and / or airfoil support plates are detachably plugged into the fabric layer; or the soft plastic support strips and / or airfoil support plates are fixedly connected to the fabric layer.

[0016] According to another aspect of the present invention, a posture correction belt is also provided, which includes the aforementioned back support.

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

[0018] This utility model's back support features a wing-shaped support plate whose radius of curvature dynamically matches the physiological lordosis angle of the lumbar spine, avoiding localized pressure concentration caused by traditional plank supports. Symmetrically arranged wing-shaped support plates precisely cover the lower serratus posterior and middle and lower erector spinae muscles, forming a directional mechanical loading on deep stabilizing muscle groups and effectively distributing muscle load. The two sets of wing-shaped plates form a centripetal converging force system, generating an equivalent supporting torque along the midline of the spine. The intermittent dynamic stress applied by the wing-shaped support plates stimulates the erector spinae muscles to produce an adaptive contraction response. Through the "biomechanical clamping effect" formed by the double-wing-shaped support plates, lateral spinal displacement is reduced, and the peak pressure at the posterior edge of the intervertebral disc is lowered, effectively preventing abnormal contractures of the intervertebral joints. The fabric layer, combined with the gradually flexible transition zone at the edge of the wing-shaped plates, reduces the standard deviation of skin contact pressure and extends the wearing tolerance time. During rapid torso rotation, the support system can deform accordingly, ensuring freedom of movement while maintaining effective support, and reducing the deviation rate of lumbar spine movement trajectory. Through the synergistic effect of biomechanical adaptive design, precise mechanical loading mechanism and dynamic response characteristics, it breaks through the technical defects of traditional posture correction products of "static fixation-muscle inhibition" and achieves the organic unity of the three functions of "support-exercise-protection".

[0019] In addition to the objectives, features, and advantages described above, this utility model has other objectives, features, and advantages. The present utility model will now be described in further detail with reference to the figures. Attached Figure Description

[0027] 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.

[0028] Figure 1 is a schematic diagram of the back support structure of a preferred embodiment of the present invention; Figure 2 is a schematic diagram of the wing-shaped support plate structure of a preferred embodiment of the present invention; Figure 3 is a schematic diagram of the back support structure acting on human muscles in a preferred embodiment of the present invention; Figure 4 is a schematic diagram of the back support structure acting on the thoracic and lumbar vertebrae in a preferred embodiment of the present invention.

[0029] As shown in Figures 1, 2, 3, and 4, the back support in this embodiment includes a fabric layer 100 and a wing-shaped support plate 200. The fabric layer 100 is used to fit in close contact with the human body to increase comfort. Two sets of wing-shaped support plates 200 are provided, and the two sets of wing-shaped support plates 200 are symmetrically attached to the fabric layer 100. The wing-shaped support plates 200 are used to fit and support the serratus posterior inferior muscle and the middle and lower erector spinae muscles on the corresponding sides. Through the coordinated cooperation of the two sets of wing-shaped support plates 200, the spine is supported from both sides and the spine is limited. This utility model's back support features a wing-shaped support plate 200 whose radius of curvature dynamically matches the physiological lordosis angle of the lumbar spine, avoiding localized pressure concentration caused by traditional plank supports. The symmetrically arranged wing-shaped support plates 200 precisely cover the lower serratus posterior and middle and lower erector spinae muscles, forming a directional mechanical loading on deep stabilizing muscle groups and effectively distributing muscle load. The two sets of wing-shaped plates form a centripetal converging force system, generating an equivalent supporting torque along the midline of the spine. The intermittent dynamic stress applied by the wing-shaped support plates 200 stimulates the erector spinae muscles to produce an adaptive contraction response. Through the "biomechanical clamping effect" formed by the double wing-shaped support plates 200, lateral spinal displacement is reduced, and the peak pressure at the posterior edge of the intervertebral disc is lowered, effectively preventing abnormal contracture of the intervertebral joints. The fabric layer 100, combined with the gradually flexible transition zone at the edge of the wing-shaped plates, reduces the standard deviation of skin contact pressure and extends the wearing tolerance time. During rapid torso rotation, the support system can undergo dynamic deformation, ensuring freedom of movement while maintaining effective support, and reducing the deviation rate of lumbar spine movement trajectory. Through the synergistic effect of biomechanical adaptive design, precise mechanical loading mechanism and dynamic response characteristics, it breaks through the technical defects of traditional posture correction products of "static fixation-muscle inhibition" and achieves the organic unity of the three functions of "support-exercise-protection".

[0030] As shown in Figures 1 and 2, in this embodiment, the wing-shaped support plate 200 includes a first plate portion 201 and a second plate portion 202 arranged sequentially from bottom to top. The first plate portion 201 is arranged along the middle and lower erector spinae muscles and fits the middle and lower erector spinae muscles. The second plate portion 202 is arranged with its free end inclined toward the direction of the lower serratus posterior muscle and fits the middle and lower erector spinae muscles and the lower serratus posterior muscle at the same time. An inflection point G is formed between the first plate portion 201 and the second plate portion 202. The first plate 201 is positioned along the direction of the lower middle erector spinae muscle belly, precisely covering the area with the largest cross-sectional area of ​​the erector spinae muscle, providing vertical main support force to directly counteract the lumbar flexion torque; the second plate 202 extends at an obtuse angle towards the lower serratus posterior muscle, its axis matching the direction of the lower serratus posterior muscle fibers, activating the lower serratus posterior-thoracolumbar fascia biomechanical chain through oblique traction force; the inflection point G corresponds to the biomechanical neutral axis of the lumbar spine, ensuring that the support force line precisely passes through the pressure center of the posterior edge of the intervertebral disc, avoiding the generation of harmful shear forces; the vertical support force of the first plate 201 and the oblique traction force of the second plate 202 combine at the obtuse angle inflection point G to form an equivalent torque, meeting the torque threshold required for lumbar spine stability; the vertical load is directly transmitted to the pelvis through the first plate 201, and the remaining load is transmitted obliquely through the second plate 202. The pressure is distributed to the thoracolumbar fascia and the serratus posterior inferior muscle; the obtuse angle design of the inflection point G allows the wing-shaped support plate 200 to flex in the sagittal plane, corresponding to the normal flexion range of the lumbar spine, thus improving lateral bending stiffness; the inclined linear traction of the second plate 202 generates pretension in the serratus posterior inferior muscle, inducing synergistic contraction of the erector spinae and multifidus muscles, forming a dual mechanism of "passive support + active stability"; the straight plate design of the first plate 201 ensures that the pressure is evenly distributed along the longitudinal direction of the erector spinae muscles, avoiding the edge effect of traditional curved plates; the inclined linear extension of the second plate 202 shifts the pressure peak area from the rib margin to the junction of the erector spinae and serratus posterior inferior muscles, reducing the depth of skin indentations; the double straight plate structure generates reverse deformation when the human body bends laterally, tracking the dynamic displacement of the muscle group in real time and maintaining continuous and effective support. Through the triple mechanism of biomechanical adaptation and fitting of the first plate 201 and the second plate 202, obtuse angle mechanical synthesis, and dynamic deformation response, the synergistic optimization of support strength, freedom of movement, and muscle function maintenance is achieved.

[0031] As shown in Figures 1 and 2, in this embodiment, the angle between the first plate portion 201 and the second plate portion 202 is 160° to 170°. When the angle between the first plate portion 201 and the second plate portion 202 is 160°-165°, the supporting force line accurately passes through the principal stress direction of the middle and lower erector spinae muscle fibers, and the electromyographic signal shows an improvement in muscle activation efficiency. When the angle between the first plate portion 201 and the second plate portion 202 is 165°-170°, the second plate portion 202 applies pretension to the serratus posterior inferior muscle, inducing muscle proprioceptive feedback and enhancing dynamic stability. The angle between the first plate portion 201 and the second plate portion 202 is 160° to 170°, allowing the wing-shaped support plate 200 to produce 12°-15° adaptive deformation when the lumbar spine is flexed forward by 30°, while the rigidity limitation is not significantly reduced. When the angle between the first plate 201 and the second plate 202 is less than 160°, the peak pressure in the inflection point G region increases, increasing the risk of inflammation at the erector spinae muscle attachment point. A small angle leads to increased sagittal flexion stiffness, restricting the lumbar flexion angle and reducing the practicality of the garment. When the angle between the first plate 201 and the second plate 202 is greater than 170°, the angle between the pulling force direction of the second plate 202 and the direction of the serratus posterior inferior muscle increases, resulting in a decrease in effective force component and insufficient composite torque. A large angle weakens control over lumbar rotation, causing the axial rotation angle to recover, thus losing its orthopedic significance. An angle range of 160°-170°, through precise adjustment of the biomechanical vector ratio and anatomical adaptation, maximizes the preservation of functional mobility while maintaining lumbar stability, overcoming the contradiction of "excessive restriction - insufficient support" in traditional posture correction products. Exceeding this range will lead to a significant decrease in biomechanical efficacy or a surge in the risk of clinical side effects.

[0032] In this embodiment, the maximum spacing between the two sets of wing-shaped support plates 200 is 10cm to 14cm; and / or the minimum spacing between the two sets of wing-shaped support plates 200 is 3cm to 5cm. The maximum spacing between the two sets of wing-shaped support plates 200, at 10cm-14cm, covers the lateral edge of the erector spinae muscle to the anterior edge of the serratus posterior inferior muscle, with the support area accounting for 85%-92% of the projection area of ​​the erector spinae-serratus posterior inferior muscle complex. When the maximum spacing between the two sets of wing-shaped support plates 200 is >14cm, the pressure transmission efficiency of the lateral erector spinae muscle decreases, the anti-lateral bending moment is insufficient, the lumbar scoliosis angle returns to near normal, and the corrective significance is lost; excessively wide spacing leads to increased lateral tension of the thoracolumbar fascia, increasing the risk of inducing fascial inflammation. When the maximum distance between the two sets of wing-shaped support plates 200 is less than 10cm, it only covers less than 50% of the medial area of ​​the erector spinae muscles, leading to compensatory contraction of the lateral erector spinae muscles and accelerating muscle fatigue. The narrow distance causes the lateral edge of the wing-shaped support plates 200 to compress the lower ribs, resulting in an increase in local pressure peaks and easily triggering intercostal neuralgia. The minimum distance between the two sets of wing-shaped support plates 200 is 3-5cm, preserving physiological space for movement in the midline of the spine (spinous process region), avoiding compression of the supraspinous and interspinous ligaments, and forming a mechanical clamping zone to limit lateral slippage of the lumbar vertebrae. When the minimum distance between the two sets of wing-shaped support plates 200 is greater than 5cm, there is no effective mechanical constraint in the midline region of the spine, increasing lateral slippage of the lumbar vertebrae and raising the intervertebral disc shear stress; the lack of support in the midline region leads to insufficient activation of the multifidus muscle and decreased segmental stability of the lumbar vertebrae. When the minimum distance between the two sets of wing-shaped support plates 200 is less than 3cm, the inner edge of the wing-shaped support plate 200 directly compresses the spinous process, increasing the local pressure and increasing the risk of periostitis; too small a distance restricts the lumbar spine rotation angle too much, shortening the wearing tolerance time.

[0033] In this embodiment, the length dimension of the wing-shaped support plate 200 is 15cm to 18cm; and / or the width dimension of the wing-shaped support plate 200 is 4cm to 6cm. The length dimension of the wing-shaped support plate 200, 15cm-18cm, covers the lumbar spine to the upper edge of the sacrum, completely encompassing the middle and lower erector spinae muscles and the lower serratus posterior muscle. The support area occupies most of the target muscle group's projection area, avoiding the problem of unbalanced spinal load distribution caused by traditional support plates. When the length dimension of the wing-shaped support plate 200 is >18cm, the lower end of the wing-shaped support plate 200 extends into the sacral foramen area, increasing local pressure and potentially increasing the risk of sacral pain; excessive length leads to excessive anti-flexion torque, restricting the lumbar flexion angle and shortening the wearing tolerance time. When the length dimension of the wing-shaped support plate 200 is <15cm, it does not cover the support structure of the lower lumbar spine, increasing pressure on the posterior edge of the intervertebral disc and accelerating the risk of intervertebral disc degeneration; the short lever arm results in insufficient anti-flexion torque, reducing lumbar spine stability. The width of the wing-shaped support plate 200 is 4cm-6cm, laterally covering the lateral edge of the erector spinae muscle to the medial band of the multifidus muscle, forming a full-width wrap around the erector spinae-thoracolumbar fascia complex. The edge of the wing-shaped support plate 200 maintains a safe distance from the lower edge of the 12th thoracic vertebra to avoid compression of the thoracic spine. When the width of the wing-shaped support plate 200 is >6cm, the lateral side of the wing-shaped support plate 200 compresses the posterior segment of the ribs, increasing the incidence of intercostal neuralgia; the excessively wide design restricts the contraction space of the transverse abdominis muscle, reducing the efficiency of abdominal synkinesis and weakening core stability. When the width of the wing-shaped support plate 200 is <4cm, the lateral region of the erector spinae muscle is unsupported, leading to an increase in the peak pressure in the remaining area and an increased risk of inflammation at the erector spinae muscle attachment point; a narrow wing-shaped support plate 200 has a small anti-lateral bending moment, and the lumbar scoliosis angle returns to near normal, thus losing its orthopedic significance.

[0034] In this embodiment, the wing-shaped support plate 200 is made of PE soft plastic sheet with a thickness of 0.1cm to 0.4cm. The 0.1cm-0.2cm thinner section of the PE soft plastic sheet generates 8%-12% elastic deformation when the lumbar spine is flexed at 30°, providing dynamic support torque and preserving most of the normal range of motion. The 0.3cm-0.4cm thicker section of the PE soft plastic sheet has relatively high bending stiffness, providing static support torque and limiting the lumbar lateral bending angle relatively more. The wing-shaped support plate 200, using a PE soft plastic sheet with a thickness of 0.1cm-0.4cm, achieves an optimal balance between support strength, freedom of movement, and wearing comfort through a stiffness-flexibility gradient design and biomechanical adaptation. When the thickness of the PE soft plastic sheet is <0.1cm, the bending stiffness is too low, plastic deformation occurs at 30° of flexion, the support torque decreases, and fatigue life is shortened. When the thickness of the PE soft plastic board is greater than 0.4cm, the sagittal plane flexion stiffness increases dramatically, and the lumbar flexion angle is restricted.

[0035] As shown in Figure 1, in this embodiment, the back support also includes soft plastic support strips 300. Two sets of soft plastic support strips 300 are symmetrically attached to the fabric layer 100, and the two sets of soft plastic support strips 300 are respectively located on the outer side of the corresponding airfoil support plate 200. The soft plastic support strips 300 and the airfoil support plate 200 are arranged at intervals. The soft plastic support strip 300 is positioned along the junction of the posterior border of the external oblique muscle and the anterior sheath of the latissimus dorsi muscle, precisely covering the weak area of ​​the lumbar triangle and forming a lateral stability anchor point. The soft plastic support strip 300 reduces the peak pressure in the outer region of the wing-shaped support plate 200, absorbing lateral impact energy through its flexible deformation. The wing-shaped support plate 200 provides anti-flexion moment, while the soft plastic support strip 300 supplements anti-lateral bending moment. The two form a mechanical buffer zone, reducing the standard deviation of pressure in the paraspinal muscle group. The wing-shaped support plate 200 and the soft plastic support strip 300 form a stepped damping effect, reducing lumbar spine vibration acceleration under walking impact loads. The wing-shaped support plate 200 restricts excessive sagittal flexion, and the soft plastic support strip... The support strip 300 controls coronal lateral curvature, and together they achieve multi-directional controllable movement of the lumbar ball-and-socket joint. The wing-shaped support plate 200 stimulates the deep fibers of the erector spinae muscles, while the soft plastic support strip 300 activates the latissimus dorsi-thoracolumbar fascia tension, both enhancing the rhythmic coordination of the lumbar spine and pelvis. The wing-shaped support plate 200 (medial main support) and the soft plastic support strip 300 (lateral dynamic anchoring) form a double-ring biomechanical framework, covering most of the stable muscle projection area behind the spine, while preserving physiological micro-movement space through spaced placement. The hysteresis response characteristics of the soft plastic support strip 300 compensate for the rapid rigidity feedback of the wing-shaped support plate 200, forming a multi-frequency vibration damping system. This collaborative design breaks through the technical limitations of the single mechanical path in traditional posture correction products, achieving an integrated biomechanical solution of active and passive stability coordination, rigid-flexible load grading, and multi-directional dynamic adaptation through a composite support structure.

[0036] As shown in Figures 1 and 3, in this embodiment, the soft plastic support strip 300 and the wing-shaped support plate 200 together form a support width of 330mm to 380mm for the lateral aspect of the lower back. This 330mm support width precisely covers the lateral edges of the bilateral erector spinae muscles and the serratus posterior-latissimus dorsi complex band, with a support area accounting for 92%-96% of the stabilizing muscle group of the lower back; it forms a full-length wrap around the quadratus lumborum muscle, generating a lateral stabilizing moment and limiting the lumbar scoliosis angle to a reasonable range. When the support width of the soft plastic support strip 300 and the wing-shaped support plate 200 for the lateral aspect of the lower back is less than 330mm, it only covers a small area on the inner side of the erector spinae muscles, leading to compensatory contraction of the lateral erector spinae muscles and accelerating muscle strain. When the soft plastic support strip 300 and the wing-shaped support plate 200 together form a lateral support width for the lower back >380mm, the outer side of the support system compresses the posterior segment of the 12th thoracic vertebra, causing a surge in the incidence of intercostal neuralgia.

[0037] In this embodiment, the soft plastic support strip 300 and / or the wing-shaped support plate 200 are detachably plugged into the fabric layer 100; or the soft plastic support strip 300 and / or the wing-shaped support plate 200 are fixedly connected to the fabric layer 100. The specifications of the soft plastic support strip 300 and / or the wing-shaped support plate 200 can be freely changed according to waist circumference and body shape characteristics, improving the fit rate. The soft plastic support strip 300 and / or the wing-shaped support plate 200 can be detached and washed separately, extending the machine wash life of the fabric layer 100. If one side of the soft plastic support strip 300 and / or the wing-shaped support plate 200 is damaged, it can be replaced independently, reducing maintenance costs. Fine-tuning of the plug hole positions avoids long-term pressure on the same area. In the later stages of rehabilitation, the soft plastic support strip 300 is removed, while the wing-shaped support plate 200 is retained for progressive muscle strengthening training. The soft plastic support strip 300 and / or the wing-shaped support plate 200 are heat-fused together with the fabric layer 100, increasing the vertical load distribution path and reducing intervertebral disc pressure. The integral molding of the soft plastic support strip 300 and / or the wing-shaped support plate 200 with the fabric layer 100 reduces costs and improves mass production consistency. Optionally, the wing-shaped support plate 200 is fixed to ensure stable main support torque, while the soft plastic support strip 300 is detachable for fine-tuning lateral stiffness to meet dynamic rehabilitation needs. Optionally, the soft plastic support strip 300 and / or the wing-shaped support plate 200 with the fabric layer 100 employs a composite design of Velcro and interlocking grooves, allowing for quick switching between "fixed" and "detachable" modes, adapting to acute phase immobilization and active training scenarios during the recovery phase.

[0038] The posture correction belt in this embodiment includes the back support described above.

[0039] In practice, a posture corrector belt with a pair of wing-shaped support plates is provided. The narrowest distance between the pair of wing-shaped support plates is 4 cm, the longest distance is 6 cm, the vertical length is 15-18 cm, and the horizontal coverage width is 13-15 cm, which can cover the middle and lower erector spinae muscles of the human body. The wing-shaped design conforms to the natural curvature of the lumbar spine and fits the waist curve. It solves the problem of the lumbar support plates of traditional posture corrector belts not fitting properly, provides necessary support for the serratus posterior and erector spinae muscles and other surrounding muscle tissues, reduces muscle burden, supports and fixes the spine while not restricting the range of motion in other directions, and achieves the purpose of support and fixation through a combination of dynamic and static external force support and voluntary exercise. It can also prevent the adverse consequences of long-term continuous fixation, such as disuse atrophy of lumbar muscles, decreased muscle strength, and spinal joint contracture and stiffness.

[0040] This posture corrector includes a waist belt with a pair of wing-shaped support plates 200 on the waist belt, and a pair of soft plastic support strips 300 on both sides of the wing-shaped support plates 200. The wing-shaped support plates 200 are made of lightweight soft plastic PE board with a thickness of 0.2 cm.

[0041] The narrowest gap between the pair of wing-shaped support plates 200 is 4 cm, and the longest gap is 12 cm. The vertical length is 15-18 cm, and the horizontal coverage width is 13-15 cm. Through in-depth research in ergonomics, it has been found that the width of the human spine, composed of multiple vertebrae, is affected by factors such as age, gender, body type, and health condition. The width also varies depending on the location. Generally, the total height of the lumbar spine in adults is usually around 15 to 20 cm, and the width of the lumbar vertebrae is approximately 3-5 cm. The pair of wing-shaped support plates 200 in this posture corrector have a vertical coverage length of 15-18 cm and a horizontal coverage width of 13-15 cm, which can completely cover the lumbar spine area. The gap between the pair of wing-shaped support plates 200 cleverly avoids the spinous processes of the thoracic and lumbar vertebrae (see Figure 4, overall view of the spine). The coverage of the wing-shaped support plates 200 starts vertically along the lower boundary of the twelfth thoracic vertebra, providing support for the lumbar vertebrae, and extends to the horizontal line of the fifth lumbar vertebra, providing necessary support for the surrounding muscle tissues such as the serratus posterior and erector spinae muscles, and reducing the burden on the muscles.

[0042] The wing-shaped support plate 200 has a fabric layer 100 covering the side closest to the torso to increase comfort and reduce the resistance of the support plate to the skin, thus avoiding discomfort. The soft plastic support strip 300 also provides support for the external oblique muscles on the back, and its fabric layer 100 increases fit and comfort.

[0043] As shown in Figure 2, the wing-shaped support plate 200 has an inflection point G in its middle. The wing-shaped support plate 200 is perpendicular to the ground below inflection point G, and the arc H between the wing-shaped support plate 200 and the line perpendicular to the ground above inflection point G is 70-80 degrees. This allows it to conform to the lumbar curve, primarily covering the iliocostalis and longissimus muscles of the erector spinae. The erector spinae muscles, a common cause of lower back pain, are located on both sides of the spine, extending from the lumbar region to the neck. The erector spinae muscles include the iliocostalis, longissimus, and spinae. When a person stands or sits, habitually hunching over, bending forward, or extending their head forward, the erector spinae muscles must continuously exert force, easily leading to continuous stretching and stiffness, resulting in muscle strain. The upper part of the wing-shaped support plate 200 increases the contact area with the erector spinae muscles, covering the erector spinae muscles (longissimus and iliocostalis) in the lower back, providing support. The curved design at both ends prevents abrasion of muscles and skin during spinal movement.

[0044] The wing-shaped support plate 200 and the soft plastic support strip 300 form a 350mm horizontal support width for the lower back. Combined with the elastic fabric that gently presses against the abdomen, the posture corrector belt's lumbar support not only supports and fixes the spine but also does not restrict movement in other directions. This achieves a combination of dynamic and static external support and self-exercise, thus providing support and fixation. It also prevents long-term continuous fixation from causing disuse atrophy of the lumbar muscles, decreased muscle strength, and spinal joint contractures and stiffness. The improved lumbar fit also enhances the flexibility of use.
