Description

Technology Field

[0001] The present invention relates to a compression belt for the sacroiliac joint designed to maintain normal sacral tilt. Background Technology

[0002] The sacroiliac joint is an anatomical structure consisting of two joints located between the sacrum below the lumbar vertebrae and the hip bones (iliac bones) on both sides, situated behind the spine. It is the most central major joint in the human skeletal system.

[0003] The stability of the sacroiliac joint consists of force closure by muscles (muscle stability) and form closure by ligaments (ligament stability); however, the sacroiliac joint can become unstable due to deformative factors such as weakening of the closure mechanism, aging, and poor posture. An unstable sacroiliac joint affects gait, physical work, and functional activities, causing compensatory reactions in the surrounding musculoskeletal system, which can lead to symptoms such as lower back pain, pelvic girdle pain, and hip pain.

[0004] The representative movements of the sacroiliac joint are the two movements shown in Fig. 1a, which appear in the anterior-posterior direction in the sagittal plane (left and right planes when looking at the front of the body) relative to the coronal axis.

[0005] 1) Nutation (NT) is a movement in which, due to forward flexion, the spine tilts forward relative to the pelvis, causing the base of the sacrum to move forward and the inferior lateral angle of the sacrum to move backward, thereby placing a nutation load on the sacroiliac joint. 2) Counter-nutation (CNT) is a movement in which, conversely, due to extension (backward tilting), the base of the sacrum moves backward and the inferior lateral angle of the sacrum moves forward, placing a counter-nutation load on the sacroiliac joint.

[0006] The two movements of the sacroiliac joint (NT and CNT) within the normal range each occur within a range of 3°, but repeated movements exceeding this abnormal range can cause lower back pain accompanied by inflammation around the sacroiliac joint (Meanwhile, in addition to the above NT and CNT movements, rotational and lateral flexion movements of the sacroiliac joint occur, but since they are very limited to ranges of approximately 1.5° and 0.8°, respectively, they are not specifically considered).

[0007] Therefore, conventional sacroiliac joint belts are configured with a specific width (or shape) so as not to compress the lumbar region at the height where the sacroiliac joint is located, and the focus is on the function of correcting posture by selectively providing compressive force only to the sacroiliac joint located below the lumbar region. For example, prior art document 1 (Japanese Patent Publication No. 2023-015771) describes a device for correcting the position of the sacrum and ilium. When a difference in the NT direction of the sacroiliac joint is recognized as a result of an examination, a moment force in the forward tilting direction is applied to the ilium (112) according to the tension of the strap (6) (see dotted arrow) for the CNT procedure (see solid arrow), and a moment force in the backward rotation direction is applied to the ilium (106) according to the pressure of the pad (4) (see white arrow), thereby demonstrating the effect of performing the CNT function as a correction device. In addition, for the NT procedure, the belt is inverted vertically so that the tension of the strap applies a moment force in the backward tilting direction to the ilium, and the pressure of the pad applies a moment force in the forward rotational direction to the ilium, thereby enabling the device to perform the NT function as an orthodontic device.

[0008] However, in the conventional belt surrounding the sacroiliac joint as described above, by simultaneously supporting the normal sacral tilt (35–50°) and the anterior pelvic tilt (about 13°), it is closely supported to the anatomical pelvic alignment, and thus 1) provides an accurate compressive force to the sacroiliac joint and 2) does not provide a method to minimize the up-and-down slippage of the belt fixation part that may occur because the existing linear belt does not adhere to the shape of the rounded pelvis.

[0009] In addition, there is a problem in that there is no belt design that includes an assistive function to maintain the normal sacral angle range (35~50°) and a corrective function to compress in abnormal sacral angle ranges (less than 35°, more than 50°) that deviate from this range. The problem to be solved

[0010] The objective of the present invention is to provide a sacroiliac joint belt that preserves rotational movement of the sacrum within the normal sacroiliac tilt range and prevents rotational movement of the sacrum within the abnormal sacroiliac tilt range, thereby maintaining a normal sacroiliac tilt (35 to 50°).

[0011] In addition, it aims to preserve and support the rotational movements (NT, CNT) of the sacrum to maintain normal sacral tilt, while simultaneously allowing natural movement of the spine and pelvis.

[0012] Specifically, by allowing the normal anterior pelvic tilt (tilt of approximately 10–15°) in the sagittal plane of a standing position, the belt can maintain its close fit (fit) to specific parts of the body, and while the belt is in close contact with the body, it preserves / supports the normal sacral tilt range while effectively inhibiting rotational movement of the sacrum in the abnormal sacral tilt range (less than 35° and greater than 50°). means of solving the problem

[0013] One embodiment of the present invention provides a compression belt for a sacroiliac joint designed to be mounted on a part of the body having a sacroiliac joint and to maintain a normal sacral inclination, comprising: a non-stretchable belt body that can be mounted on said part of the body; a flexible pad portion located at the center in the extension direction of said belt body and installed on an inner surface in the thickness direction to preserve rotational movement of said sacrum in a normal sacral inclination range (35 to 50°); and a pair of elastic wing portions formed extending from the center to both sides in the extension direction of said belt body and installed on an outer surface in the thickness direction to prevent rotational movement of said sacrum in an abnormal sacral inclination range (less than 35° and greater than 50°).

[0014] The above-mentioned non-stretchable belt body may include a first area in which the flexible pad portion is installed on the inner side and the elastic wing portion is installed on the outer side, in the direction of extension of the belt body when the belt is worn, surrounding the rear of the body including the sacrum; a second area in which the elastic wing portion is installed connectedly on the outer side, surrounding both sides of the body including the anterior superior iliac spine; and a third area in which the belt's connecting portion is installed, surrounding the front of the body including the pubic bone.

[0015] The above flexible pad portion may be a) composed of a viscoelastic material, b) formed with a gradient in which the thickness decreases from the top to the bottom with respect to the width direction, and the cross-sectional shape may include a protrusion that forms an angle of 35 to 50° between the side of the belt body and the side of the body when the belt is worn, thereby c) preserving the rotational movement of the sacrum in the nutation / counter-nutation direction up to the maximum / minimum normal sacral inclination (50° / 35°).

[0016] The elastic wing portion may include a) a stretchable material, b) a first pressure wing extending from the center / upper end / lower end based on the extension / width direction of the belt body; and a second pressure wing extending from the center / lower end / upper end, thereby c) applying pressure to the rotational movement of the sacrum in the nutation direction in the counter-nutation direction when the abnormal sacral inclination range exceeds 50°, and applying pressure in the nutation direction when the abnormal sacral inclination range is less than 35°.

[0017] A compression belt according to one embodiment of the present invention may further include an elastic connecting portion located in a second region of the belt body and installed in connection with at least a part of the belt body in the extension direction of the belt body, and which is stretchable in the extension direction of the belt body in response to the occurrence and disappearance of anterior pelvic tilt and / or increase and decrease in the circumference of the pelvis.

[0018] The above elastic connecting part may be a) a) a stretchable material, b) located at the bottom with respect to the width direction, and formed with a gradient in which the thickness increases from the top to the bottom and from both ends of the belt body to the center with respect to the width direction and the extension direction, and the cross-sectional shape may be formed at an angle of 10 to 15° between the first area side surface and the bottom side surface, thereby c) when the anterior tilt of the pelvis occurs or disappears, the length of the elastic connecting part increases or decreases in the extension direction and width direction of the belt body, and when the circumference of the pelvis increases or decreases, the length of the elastic connecting part increases or decreases in the extension direction of the belt body.

[0019] In one embodiment of the present invention, the elastic wing portion may be formed such that, with respect to the belt body, a) the upper and lower lengths of the second region of the belt body are each longer than the upper and lower lengths of the first region of the belt body, respectively, with respect to the centerline in the width direction; b) the elastic wing portion may be formed such that, with respect to the width direction of the belt body, the first pressure wing is installed in a diagonal line extending from the upper part of the first region of the belt body to the lower part of the second region, and the second pressure wing is installed in a diagonal line extending from the lower part of the first region of the belt body to the upper part of the second region, and c) the intersection point of the first pressure wing and the second pressure wing may be located in the first region of the belt body.

[0020] In one embodiment of the present invention, the elastic wing portion may be configured such that, with respect to the elastic connection portion, a) the elastic connection portion is configured to include an upper portion and a lower portion of the elastic connection portion with respect to a centerline in the width direction, and b) the elastic wing portion may be installed at a position where the first pressure wing and the second pressure wing overlap or exceed at least a portion of the upper portion of the elastic connection portion with respect to the width direction of the belt body. Effects of the invention

[0021] According to the present invention, by simultaneously supporting normal sacral tilt (35~50°) and anterior pelvic tilt (about 13°), the anatomical pelvic alignment is closely supported, resulting in 1) providing an accurate compressive force to the sacroiliac joint and 2) minimizing the up-and-down slippage of the belt fixing part that may occur when the existing linear belt does not adhere to the shape of the rounded pelvis.

[0022] It can simultaneously provide an auxiliary function to maintain the normal sacral angle range (35~50°) and a corrective function to compress in abnormal sacral angle ranges (less than 35°, more than 50°) that deviate from this range. Brief explanation of the drawing

Specific details for implementing the invention

[0024] The advantages and features of the present invention and the methods for achieving them will become clear by referring to the embodiments described below in detail together with the accompanying drawings. However, the present invention is not limited to the embodiments disclosed below but may be implemented in various different forms. These embodiments are provided merely to ensure that the disclosure of the present invention is complete and to fully inform those skilled in the art of the scope of the invention, and the present invention is defined only by the scope of the claims.

[0025] Unless otherwise defined, all terms used in this specification (including technical and scientific terms) may be used in a meaning that is commonly understood by those skilled in the art to which the present invention belongs.

[0026] When a part of a specification is described as "comprising" a certain component, unless specifically stated otherwise, this means that it does not exclude other components but may include additional components. Furthermore, the singular form includes the plural form unless specifically stated otherwise in the text.

[0027] In this specification, when a part such as a layer, membrane, region, plate, structure, frame, member, or section is described as being “on” or “on top of” another part, this includes not only cases where it is “immediately on” another part, but also cases where there is another part in between.

[0029] One embodiment of the present invention provides a compression belt for a sacroiliac joint that is mounted on a part of the body having a sacroiliac joint and is designed to maintain a normal sacral inclination.

[0030] FIG. 2 is a schematic diagram (a) viewed from the inside and a schematic diagram (b) viewed from the outside of the belt of a compression belt for a sacroiliac joint according to one embodiment, and FIG. 3 is a schematic diagram of the compression belt for a sacroiliac joint mounted on a specific part of the body, viewed from the front (left), back (middle), and side (right).

[0031] Referring to FIGS. 2 and 3, the belt (10) comprises: a non-stretchable belt body (100) that can be mounted on a part of the body having a sacroiliac joint; a flexible pad portion (200) located in the center in the extension direction of the belt body and installed on the inner side in the thickness direction to preserve rotational movement of the sacrum in a normal sacral inclination range (35 to 50°); and a pair of elastic wing portions (300) formed extending from the center to both sides in the extension direction of the belt body and installed on the outer side in the thickness direction to prevent rotational movement of the sacrum in an abnormal sacral inclination range (less than 35° and greater than 50°).

[0032] Conventional sacroiliac joint belts are configured with a width that does not compress the lumbar region at the height where the sacroiliac joint is located, and thus have limitations in that they focus only on the function of correcting abnormal posture by selectively providing compressive force only to the sacroiliac joint located below the lumbar region. However, the present invention provides a sacroiliac joint belt that preserves rotational movement of the sacrum within the normal sacroiliac tilt range and inhibits rotational movement of the sacrum within the abnormal sacroiliac tilt range, thereby maintaining a normal sacroiliac tilt (35~50°).

[0034] As shown in FIGS. 2 and 3, the belt body (100) is formed to extend so as to be mounted in close contact with specific parts of the body, including the sacrum and sacroiliac joint on the rear side of the body, the anterior superior iliac spine on both sides, and the pubic bone on the front, and the upper and lower width, thickness, and shape of each part (region) are appropriately designed to reduce the burden on the body and are mounted on the body.

[0035] The above belt body (100) may be provided with a non-stretchable material, and thus, when the sacrum rotates within an abnormal sacral inclination range, the protrusion of the upper and lower rearward in the width direction of the belt body can be compressed and prevented by the non-elastic properties of the belt body. For example, the non-stretchable material of the belt body may be nylon, non-slip silicone rubber, polyurethane, neoprene, etc., and is not particularly limited as long as it provides a soft and comfortable feel in the part that contacts the body, does not slip, and has non-elastic and non-stretchable properties.

[0036] Meanwhile, the term "inelastic and non-stretchable materials" used here generally excludes materials in which high elasticity or high stretchability characteristics are particularly emphasized, and includes materials having substantially low stretchability or low elasticity, such as low elasticity and low stretchability materials; it does not refer to materials that do not stretch at all physically or chemically or lack elasticity.

[0037] As in one embodiment, the belt body (100) sequentially includes first to third regions (110, 130, 150), and the left side (one side) and the right side (the other side) may be symmetrically formed with respect to the center line (L1) of the first region in the extension direction of the belt body.

[0038] Specifically, the first region (110) may surround the rear of the body including the sacrum when the belt is worn, with the flexible pad portion (200) installed on the inner side and the elastic wing portion (300) installed on the outer side. Additionally, the second region (130) may surround both sides of the body including the anterior superior iliac spine when the belt is worn, with the elastic wing portion (300) installed connectedly on the outer side. Furthermore, the third region (150) may surround the front of the body including the pubic bone when the belt is worn, with the belt's connecting portion (not shown) installed on the inner and outer sides.

[0039] The connecting portion of the belt is installed on the inner and outer surfaces of the third area (150), respectively, and may include a Velcro fastening member and / or a buckle including a hook surface or a loop surface, thereby allowing the belt to be effectively attached to a specific part of the body by easily attaching and detaching the connecting portion.

[0041] As shown in FIGS. 2 and 3, the flexible pad portion (200) is intended to preserve rotational movement of the sacrum within a normal sacral inclination range (35 to 50°) and is located in the center (first region of the belt body) in the extension direction of the belt body and installed on the inner surface in the thickness direction.

[0042] As in one embodiment, the flexible pad portion (200) may be installed at a position corresponding to the sacrum below the lumbar vertebrae located behind the spine as a first region of the belt body (center in the extension direction of the belt body); and two joints (sacroiliac joints) located between the two iliac bones (hip bones).

[0043] At this time, the flexible pad portion (200) may have a shape on the front or rear that has a gradient in which the width narrows from top to bottom with respect to the width direction, for example, it may include the shape of an inverted triangle, an inverted trapezoid, an inverted polygon, and / or a fan shape, and it is obvious that some straight lines on the front or rear of the flexible pad portion may be replaced with curves such as arcs so as to correspond to the shape of the sacrum. Accordingly, it is possible to wear a comfortable and close-fitting belt that sufficiently surrounds the sacrum and sacroiliac joint, connects to both sides of the lower end of the sacrum, and does not rest on the protruding ilium (hip and pelvic bone).

[0044] Specifically, the flexible pad portion (200) is installed on the inner side in the thickness direction of the belt body and may have a shape that protrudes toward the body side when the belt is worn (hereinafter, protrusion). Accordingly, in the normal sacral inclination range of 35 to 50°, the rotational movement of the sacrum presses against the protrusion of the flexible pad portion, and as the flexible protrusion is formed according to the shape of the sacrum, the rotational movement of the sacrum can be supported and preserved. In addition, when the abnormal sacral inclination range is less than 35° or greater than 50°, the rotational movement of the sacrum exceeds the maximum formed shape of the protrusion of the flexible pad portion and subsequently presses against the belt body located on the outer side of the flexible pad portion, the rotational movement of the sacrum (in the abnormal sacral inclination range) can be compressed and inhibited by the inelastic characteristics of the belt body described above and the elastic characteristics of the elastic wing portion described later.

[0045] As in one embodiment, the flexible pad portion (200) may include a) a viscoelastic material. Since the viscoelastic material has both viscosity that absorbs and dissipates shock and elasticity that bounces back in response to shock, it stably absorbs the pressure applied during the rotational movement of the sacrum and forms a shape (viscous characteristic), thereby reducing the amount of shaking or force released again, so it can support and preserve the rotational movement of the sacrum. At the same time, when the rotational movement of the sacrum is restored and returns to its original position, the flexible pad portion can return to its original shape (low elasticity characteristic). Examples of the types of viscoelastic materials include memory foam, latex, gel cushion, air cushion, and bulletproof foam (HR Foam). Specifically, the flexible pad portion (200) is not particularly limited as long as it is a viscoelastic material having a rebound elasticity of less than 30% (shock absorption rate exceeding 70%), preferably 30% or less (shock absorption rate exceeding 70%), 25% or less (shock absorption rate exceeding 75%), and more preferably 20% or less (shock absorption rate exceeding 80%) as measured by a ball-rebound tester (DIN EN ISO 8307).

[0046] In addition, as shown in FIG. 4a, the flexible pad portion (200) is formed with a gradient in which the thickness decreases from the top to the bottom with respect to b) the width direction, and may include a protrusion that forms an angle of 35 to 50° between the side of the belt body and the side of the body when the belt is worn, and specifically, the cross-sectional shape may include an inverted triangle, an inverted trapezoid, and / or an inverted polygon that forms an angle of 35 to 50° between the side of the belt body and the side of the body when the belt is worn, and it is obvious that some straight lines in the cross-sectional shape may be replaced with curves such as arcs so as to correspond to the shape of the sacrum.

[0047] Accordingly, c) during rotational movement in the nutation direction of the sacrum, the rotation of the sacrum can be supported and preserved up to a maximum normal sacral inclination of 50° (see left side of Fig. 4b), and conversely, during rotational movement in the counter-nutation direction, the rotation of the sacrum can be supported and preserved up to a minimum normal sacral inclination of 35° (see right side of Fig. 4b).

[0049] The elastic wing portion (300) is intended to prevent and compress rotational movement of the sacrum in an abnormal sacral inclination range (less than 35° and greater than 50°), and is formed extending from the center to both sides in the extension direction of the belt body and is installed on the outer surface in the thickness direction.

[0050] Meanwhile, the elastic wing portion (300) may be formed symmetrically on the left side (one side) and the right side (the other side) with respect to the center line (L2) in the extension direction of the belt body.

[0051] As in one embodiment, the elastic wing portion (300) may include a) an elastic material. Since the elastic material has elasticity that bounces back in response to impact, rotational movement of the sacrum in abnormal sacral inclination can be compressed and prevented, and additionally, the belt body can be pressed against the body by exerting elastic force.

[0052] Specifically, examples of the types of the above elastic materials include polyurethane, natural rubber, synthetic rubber, etc. Specifically, the above elastic wing portion is not particularly limited as long as it is an elastic material having a rebound elasticity of 30 to 90%, 50 to 90%, or 50 to 80% (shock absorption rate 20 to 50%) as measured by a ball-rebound tester (DIN EN ISO 8307).

[0053] Additionally, the elastic wing portion (300) may include b) a first pressure wing (310) extending from the center / upper to both ends / lower based on the extension / width direction of the belt body; and a second pressure wing (330) extending from the center / lower to both ends / upper.

[0054] Accordingly, the elastic wing portion (300) can apply pressure in the counter-nutation direction when the rotational movement of the sacrum in the nutation direction exceeds 50°, which is the abnormal sacral inclination range, and in the nutation direction when the abnormal sacral inclination range is less than 35°. Specifically, when the sacroiliac joint rotates in the direction of nutation with a sacral inclination exceeding 50°, the second pressure wing (330) presses the inferior lateral angle of the sacrum moving posteriorly from the posterior / inferior direction in the anterior / upper direction (rotational moment force in the CNT direction) to press and inhibit the rotation of the sacrum (see left side of FIG. 4c). Conversely, when the sacroiliac joint rotates in the direction of counter-nutation with a sacral inclination of less than 35°, the first pressure wing (310) presses the base of the sacrum moving posteriorly from the posterior / upper direction in the anterior / lower direction (rotational moment force in the NT direction) to press and inhibit the rotation of the sacrum (see right side of FIG. 4c).

[0055] In addition, the first pressure wing (310) and the second pressure wing (330) are each formed in a band shape with a length of 30% or less, 25% or less, or 5 to 20% of the width of the belt body center, so that the first pressure wing (or the second pressure wing) compresses and inhibits the rotational movement of the sacrum appearing in one direction of the belt body in an abnormal sacral inclination, while the second pressure wing (or the first pressure wing) exerts elastic force to suppress lifting of the belt body in the other direction, thereby preventing the flexible pad portion from detaching from the body and allowing the belt to be attached to the body.

[0057] The compression belt (10) of the present invention may further include an elastic connecting part (400). The elastic connecting part (400) is intended to stretch the compression belt (10) in the extension direction of the belt body in response to the occurrence and disappearance of anterior pelvic tilt and / or increase and decrease in the circumference length of the pelvis, and may be located in a second region (130) of the belt body and installed to be connected to at least a part of the belt body (100) in the extension direction of the belt body.

[0058] As in one embodiment, the elastic connecting part (400) may include a) an elastic material. Since the elastic material has elasticity that bounces back in response to impact, it has the effect of preventing the flexible pad part from detaching from the body and keeping the belt close to the body by stretching the compression belt in the extension direction of the belt body when anterior tilt of the pelvis occurs and disappears and / or the circumference length of the pelvis increases and decreases.

[0059] Specifically, examples of the types of the above elastic materials include polyurethane, natural rubber, synthetic rubber, etc. Specifically, the above elastic wing portion is not particularly limited as long as it is an elastic material having a rebound elasticity of 30 to 90%, 50 to 90%, or 50 to 80% (shock absorption rate 20 to 50%) as measured by a ball-rebound tester (DIN EN ISO 8307).

[0060] Additionally, the elastic connecting part (400) is b) located at the bottom with respect to the width direction and is formed with a gradient in which the thickness increases from the top to the bottom and from the center of the belt body (100) to both ends with respect to the width direction and the extension direction, and the cross-sectional shape may form an angle of 10 to 15° between the first area side surface and the bottom side surface, and for example, may include a (right-angled) triangle, trapezoid, or polygon that forms an angle of 10 to 15° between the first area side surface and the bottom side surface.

[0061] Accordingly, the elastic connecting part (400) may be such that when c) anterior tilt of the pelvis occurs or disappears, the length of the elastic connecting part (400) increases or decreases in the extension direction and width direction of the belt body, and when the circumference of the pelvis increases or decreases, the length of the elastic connecting part (400) increases or decreases in the extension direction of the belt body (100).

[0062] For example, as shown in FIG. 5a, when a normal anterior pelvic tilt (an inclination of approximately 10 to 15° in the sagittal plane of the body in an upright position) occurs, the first and second regions of the belt body are bent by the amount of the anterior pelvic tilt through the elastic connecting part (400), so that the first region (110) of the belt body is closely attached to the sacrum, while the second region (130) is stably connected at the anterior superior iliac spine position. This effect is amplified because the elastic connecting part (400) is formed with a gradient in which the thickness increases from the top to the bottom and from the center of the belt body to both ends in the width direction / extension direction.

[0063] In addition, as shown in FIG. 5b, the compression belt can be stretched in the extension direction of the belt body when the circumference of the pelvis increases or decreases. When a normal squat posture occurs, the lower part of the ilium (hip bone) widens, and the circumference of the lower part of the belt body in the width direction corresponding to this increases. Through the elastic connecting part (400) of the present invention, the belt body is stretched in the extension direction, so that the second region (130) is stably connected at the position of the anterior superior iliac spine, while the first region (110) of the belt body is maintained in close contact with the sacrum. This is because the elastic connecting part (400) is formed with a gradient in which the thickness increases from the top to the bottom in the width direction, thereby doubling the above-described effect.

[0065] As in another embodiment, the elastic wing portion (300) may be formed such that, with respect to the belt body, a) the second region (130) of the belt body has upper and lower lengths that are longer than the upper and lower lengths of the first region (110) of the belt body, respectively, with respect to the centerline (L2) in the width direction, b) the elastic wing portion (300) may be formed such that, with respect to the width direction of the belt body, the first pressure wing (310) is installed in a diagonal line extending from the upper part of the first region (110) of the belt body to the lower part of the second region (130), and the second pressure wing (330) is installed in a diagonal line extending from the lower part of the first region (110) of the belt body to the upper part of the second region (130), and c) the intersection point of the first pressure wing (310) and the second pressure wing (330) is located in the first region (110) of the belt body.

[0067] As in another embodiment, the elastic wing portion (300) may be configured such that, with respect to the elastic connection portion (400), a) the elastic connection portion (400) is configured to include an upper portion (401) and a lower portion (403) of the elastic connection portion with respect to a centerline in the width direction, b) the elastic wing portion (300) may be installed such that, with respect to the width direction of the belt body, the first pressure wing (310) and the second pressure wing (330) overlap or exceed at least a portion of the upper portion (401) of the elastic connection portion.

[0068] Accordingly, as described above, the elastic connecting part (400) of the second region allows for natural movement even in the changing pelvic circumference and pelvic anterior tilt situation during a squat posture in which the pelvis is tilted forward, and at the same time, the elastic wing part (300) increases the compressive force from the posterior lower part to the anterior upper part in a direction that preserves the sacral tilt in a situation where the sacrum changes in the nutation direction, thereby restricting excessive movement of the pelvic joint to prevent injury and adding stability.
