Description

The present invention relates to a roll pillow and a method of wearing a roll pillow that prevents low back pain, alleviates the symptoms of low back pain, and realizes a smooth turning over between the supine position and the lateral decubitus position of a sleeping user.

As a tool for preventing and treating low back pain, a waist belt that tightens the waist and stabilizes the lumbar spine has long been known. As an example of such a waist belt, for example, as shown in FIG. 8, the main body belt 101 is made of an elongated strip-shaped elastic material, and the main body belt 101 is wrapped around the abdomen to apply a constant tension along the longitudinal direction. A waist belt 100 is known that enhances the stability of the abdominal spine 102 by locking both ends of the main body belt in the generated state and uniformly pressing the body surface around the abdomen (Patent Document 1).

In addition, as shown in FIG. 9, in the sleeping posture in the supine position, the dent formed in the arch shape on the back side is filled, and the weight concentrated on the lumbar region and the back surface and the pressure due to the bedding are dispersed to prevent the initial low back pain. A blood circulation promoting device 110 that improves blood flow during sleep is also known (Patent Document 2).

Furthermore, as a means of achieving a smooth turn over between the supine and lateral positions of the sleeping user, the inventor of the present application puts the cervical spine in a stable position in both the supine and lateral sleeping positions. We have invented a method for adjusting the height of a pillow that can be held and dynamically turned over (Patent Document 3).

Japanese Unexamined Patent Publication No. 6-78943 Japanese Patent No. 11-566536 Japanese Patent No. 4024152

Since the waist belt of Patent Document 1 uses an elastic material for the main body belt 101 to be wound around the abdomen, even if it is wound while a certain tension is generated, the amount of bending of the main body belt 101 in the longitudinal direction due to the elastic material is equivalent. However, the lumbar spine is mobile and cannot be sufficiently stabilized.

On the other hand, it is also possible to wrap the main body belt 101 around the abdomen by generating an excessive tension exceeding the elastic limit of the elastic material, so that the abdominal pressure becomes high due to excessive tightening, which puts a burden on the internal organs in the abdominal cavity. There is also a risk of this.

Since the blood circulation promoting device 110 of Patent Document 2 only disperses the pressure received from the bedding in the supine position and does not stabilize the lumbar spine by applying pressure from the surroundings, prevention of low back pain and improvement of symptoms cannot be expected. ..

Further, the blood circulation promoting device 110 disperses the pressure received from the bedding to promote blood circulation during sleep, but in the state where the supine sleeping posture is maintained, the state in which the body pressure changes locally is long. It continues for a long time, and as a result, ischemia occurs in that part, nerve compression and abnormal posture of the vertebral pelvis occur, which causes back pain and the like.

Therefore, it is desired to repeatedly turn over between the supine and lateral positions during sleep, and according to the invention of Patent Document 3, the cervical spine is held in a stable position so that the supine and lateral positions are held. I tried to turn over without putting a burden on the cervical spine, but I haven't been able to turn over smoothly enough. That is, the rotational force for turning over between the supine and lateral decubitus positions is triggered by the rotation of the legs bent from the knees, but the chest and hips are supported by the ribs and pelvis. While it is a fixed mass, the abdomen between them flexes flexibly, so the torque in the rolling direction transmitted from the legs to the waist is absorbed by the flexible abdomen and is difficult to be transmitted to the chest. , In order to turn over, you have to turn over while lifting your hips and shoulders many times, or you have to be half awake during sleep and use extra muscles, and fatigue accumulates even during bedtime. Met.

The present invention has been made in consideration of such conventional problems, and is a method of attaching a roll pillow and a roll pillow that can smoothly turn over between the supine position and the lateral decubitus position with a comfortable force. The purpose is to provide.

In order to achieve the above object, the roll pillow according to claim 1 has an elongated band-shaped front and back surfaces made of cloth, and is wrapped around a sleeping body and a flexible wrapping band, and the wrapping band as a whole. It is a roll pillow equipped with a locking part that locks the tail end of the wrapping band to the corresponding part that appears on the surface of the lower layer while generating tension along the longitudinal direction and wrapping it around the body. hand,
The locking portion includes a first hook-and-loop fastener formed on the back surface of the tail end portion of the winding band.
It is provided with a second surface fastener formed on the surface of the corresponding portion of the wrapping band, which is in close contact with the facing first surface fastener and is locked to each other, and the wrapping band is continuous in the longitudinal direction along the upper edge. , At least a rib tightening band wrapped around the 10th rib and a longitudinal continuation along the rib tightening band below the rib tightening band, with the lower edge wrapped along the upper edge of the iliac bone and almost uniform around the abdomen. It consists of an abdominal tightening band that compresses toward its center, the lateral width of the wrapping band is narrower than the width between the iliac bone and the 8th rib, and the longitudinal length is at least ventral to the torso. The thickness of the wrapping band wrapped around the torso in the back stacking direction is approximately equal to the depth of the back dent around the torso in the recumbent position, at least the first. The 12th to 10th ribs bend inward in the torso, and the flat elliptical contour around the abdomen approaches a circle, so that the outer peripheral surface of the wrapping band approaches a cylindrical surface.

Further, in the method of attaching the roll pillow according to claim 3, the front and back surfaces of the elongated band are made of cloth, and the width in the lateral direction is narrower than the width between the ilium and the eighth rib. It is a method of attaching a roll pillow that wraps the band around the body by generating tension along the longitudinal direction around the entire wrapping band.
Wrap a longitudinally continuous rib tightening band along the strip-shaped upper edge over at least the 10th rib, and a lower edge of the longitudinally continuous abdominal tightening band below the rib tightening band along the rib tightening band. Wrap along the upper edge of the ribs, compressing the abdomen almost evenly towards its center, creating longitudinal tension throughout the wrap band, at least doubly on the ventral side of the torso. In the state of being wrapped around the torso, the first surface fastener formed at the tail end of the wrapping band is brought into close contact with the second surface fastener formed at the corresponding portion appearing on the outer surface of the lower layer and locked to each other. However, the thickness of the wrapping band on the back side in the stacking direction is almost equal to the depth of the back side depression around the torso in the supine position, and at least the 12th to 10th ribs bend inward of the torso. The flat elliptical contour around the abdomen approaches a circular shape, so that the outer peripheral surface of the wrapping band approaches a cylindrical surface.

In the inventions of claims 1 and 3 , since the front and back surfaces of the wrapping band are made of cloth, a high frictional force is generated between the layers to be wound in layers, and even if the wrapping band is turned over during bedtime, it does not loosen and is constant in the longitudinal direction. Maintain the state where the tension is generated for a long time.

Further, since the rib tightening band is wrapped from the 12th rib onto at least the 10th rib, excessive tightening by the wrapping band is restricted, and excessive abdominal pressure does not impose a burden on the internal organs in the abdominal cavity.

Since the locking positions of the first-side fastener and the second-side fastener can be adjusted, the tension generated in the longitudinal direction of the wrapping band can be adjusted to adjust the abdominal pressure generated in the abdominal cavity.

On the other hand, the 11th and 12th ribs around which the rib tightening band is wrapped are floating ribs whose anterior ends are free from other bones, and the 10th ribs are also temporary ribs whose anterior ends do not reach the sternum directly, so that they are longitudinally The abdominal tightening band, which is made of fabric and is integrated with the rib tightening band, bends slightly in the direction of the central axis of the body by being tightened by the rib tightening band that is tensioned along the rib bone. Since it is wrapped along the upper edge, it presses around the abdomen almost evenly toward its center with appropriate pressure, stabilizing the entire abdomen and the lumbar spine in the abdomen. At this time, the width of the wrapping band along the upper edge of the ilium in the lateral direction is narrower than the width between the ilium and the 8th rib, and the pelvis where the wrapping band does not deform and the true of the 1st to 7th ribs. Since it is not wrapped around the ribs, it does not interfere with the tightening of the abdomen by the abdominal tightening band.

Further, since the wrapping band is not wrapped around the true ribs of the 1st to 7th ribs above the 8th rib, it does not hinder the movement of the lungs that swell anteriorly and upwardly due to breathing, and does not cause suffocation.

The torque in the rolling direction around the body axis, which is transmitted from the legs to the waist by rotating the legs while sleeping, is hardened by tightening the abdomen with the abdominal tightening band, so that it is not attenuated by the abdomen. It is transmitted to the chest, and you can turn over with ease. In addition, when the bed rest surface is the surface of a cloth such as a bed or a mattress, the front or back surface of the wrapping band, which is the cloth, comes into contact with a high frictional force, so that the wrapping band touches the bed rest surface when turning over. You can turn over smoothly without slipping.

Furthermore, the twelfth rib around which the rib tightening band is wrapped is slightly bent in the central axial direction of the trunk by being tightened by the rib tightening band in which tension is generated along the longitudinal direction, and the rib tightening band is integrated with the fabric. Since the entire wrapping band including the abdominal tightening band uniformly tightens the body surface around the torso, the outer surface of the wrapping band approaches the cylindrical surface around the abdomen and easily rolls on the lying floor surface.

The thickness of the wrapping band on the back side in the stacking direction is approximately equal to the depth of the dent on the back side around the torso in the supine position, so the wrapping band fills the dent and is flush with the chest and buttocks on both sides thereof. In contact with the lying floor surface, the outer peripheral surface of the wrapping band guides the entire body to rotate in the turning direction.

A first surface fastener provided on the tail end of the wrapping band, by close contact with the second surface fastener provided on the surface of the corresponding portion of the underlying, locked tail end with a corresponding site of the winding band engagement, longitudinal The wrapping band wrapped around the body is held in a state where tension is generated along the direction.

The roll pillow according to claim 2 is characterized in that the wrapping band is formed of a towel cloth.

Since the wrapping band is made of towel cloth, there is no discomfort even if you touch the body surface directly, and it expands and contracts by a certain amount in the thickness direction, so it absorbs fine irregularities on the body surface when wrapped around the body, and its The outer surface approaches the cylindrical surface.

According to the invention of claim 1, since an appropriate abdominal pressure that does not burden the internal organs in the abdomen uniformly tightens the circumferences of the upper lumbar spine and the lower lumbar spine, the lumbar spine is stabilized, the occurrence of low back pain is suppressed, and low back pain is suppressed. If is occurring, the symptoms are alleviated.

Furthermore , since the lumbar spine that connects the rib cage and the pelvis, which is a fixed mass, is tightened to a certain hardness, the torque generated in the leg in the turning direction is not attenuated by rotating the leg, and the rib cage is reached. It is transmitted and turns over to rotate the entire body with a comfortable force. As a result, smooth rollovers are naturally repeated during overnight sleep, blood, lymph and joint fluid circulate, promoting thermoregulation and metabolism.

Further, according to the inventions of claims 1 and 3, the outer peripheral surface of the wrapping band wound around the body near the center of gravity of the body in the supine position close to the cylindrical surface is flush with the chest and the buttocks on both sides thereof. Since it touches the lying floor surface and acts as a rotating body that rolls on the lying floor surface, the abdomen is tightened and the rotational torque in the turning direction is transmitted from the legs to the chest without being attenuated. You can turn over by moving your body.

Further, the wrapping band can be held in a state where tension is generated in the longitudinal direction as a whole only by bringing the pair of the first surface fasteners and the second surface fasteners in close contact with each other.

Even if the pair of hook-and-loop fasteners are brought into close contact with each other and locked to each other, the thickness in the stacking direction is thin, so even if a hook-and-loop fastener that comes into close contact with the bed rest is interposed, it is absorbed by the thickness of the wrapping band of the fabric. No large irregularities occur on the outer peripheral surface of the wrapping band.

According to the invention of claim 2 , since the wrapping band is formed of a towel cloth, there is no discomfort even if it comes into direct contact with the body surface, and it expands and contracts by a certain amount in the thickness direction, so that the body is wrapped around the body. It absorbs the fine irregularities on the surface and the irregularities on the locking part of the tail end of the wrapping band, and the irregularities do not appear on the outer surface, so it does not resist the rotation of the body due to turning over.

In addition, since the wrapping band of the towel cloth is wrapped around the body including the abdomen, the abdomen is kept warm.

FIG. 5 is a side view showing a state in which the conventional blood circulation promoting device 110 is worn on a user in a supine sleeping posture.

Hereinafter, the roll pillow 1 and the method of attaching the roll pillow according to the embodiment of the present invention will be described with reference to FIGS. 1 to 7. In this specification, each part of the roll pillow 1 and its wearing direction will be described with the head direction of the user around which the roll pillow 1 is wound upward, the leg direction downward, the chest side forward, and the back side backward. To do.

As shown in FIG. 1, the roll pillow 1 is composed of a wrapping band 2 wrapped around the body of the user and a hook-and-loop fasteners 3a and 3b which are a pair of locking portions attached to the front surface and the back surface of the wrapping band 2. To. The figure shows a wrapping band 2 in an unfolded state before being wrapped around a body portion, and is formed by cutting a cloth made of a towel cloth into an elongated band shape as shown in the drawing. However, if it does not expand and contract in the longitudinal direction and at least the back surface (the surface appearing on the plane in FIG. 1) and the front surface (the surface on the bottom surface side in FIG. 1) are elongated strips, the fabric is made of synthetic fibers such as polyester fibers. It may be present, or a low-resilience material may be used as a core material and the front and back surfaces thereof may be covered with a cloth.

The width W in the lateral direction, the width L in the longitudinal direction, and the thickness t of the wrapping band 2 are set from the physical characteristics of the user. The breadth W of the winding band 2, and iliac upper 6U user wider than the width between the first 12 ribs 4 _12, a narrow or wide than the width between the iliac upper 6U and the eighth rib 4 ₈ Set. Thus, as shown in FIG. 3, the winding along the iliac upper end of the user's lower edge 2L, the upper edge 2U becomes wrapping between the eighth rib 4 ₈ to 12 ribs 4 ₁₂ of the user , The upper portion 2A of the wrap band 2 is wrapped around at least the 10th rib. In the present invention, the portion 2A shown in FIG. 1 from the portion wound on the twelfth rib to the upper edge 2U of the wrapping band 2 is referred to as a rib tightening band 2A, and is continuous in the longitudinal direction along the rib tightening band 2A. The portion wrapped around the abdomen from the lower part of the rib tightening band 2A to the lower edge 2L is called the abdominal tightening band 2B.

Due to the structure of the human skeleton, the 1st to 7th ribs 4 _{1 to} 4 ₇ are called "true ribs" whose anterior ends are connected to the lateral edge of the sternum, and the 8th to 12th ribs 4 _{8 to} 4 ₁₂ are direct. It is called "temporary ribs" that do not reach the sternum. Of the "provisional ribs", the eighth to tenth rib _{4 8-4 10} is attached immediately upper costal cartilage making "rib arch" but the eleventh rib _{4 11} 12 rib _{4 12} It is called a relatively unstable "floating rib" because the front end is free.

In the present invention, as shown in FIG. 3, the rib tightening band 2A is wound around the rib 4 from the 12th rib 4 ₁₂ to at least the 10th rib 4 ₁₀ above, so that excessive tightening around the body is restricted. Therefore, the internal organs in the abdominal cavity are not burdened by the increase in internal pressure. On the other hand, the portion of the rib tightening band 2A is wound from the relatively flexible 12th rib 4 ₁₂ to the upper 10th rib 4 ₁₀ , so that the band 2 is wound around the body while generating a certain tension. As a result, the floating ribs and temporary ribs from the 12th rib 4 ₁₂ to the 10th rib 4 ₁₀ are slightly bent inward of the body, and the circumference of the body of the elliptical contour that is longer in the left-right direction on both sides than the front-back direction is Approaching a circular contour.

The upper limit of the upper edge 2U winding band 2 eighth ribs 4 _8, since the lower limit of the lower edge 2L is iliac upper, stable and hard without being wound around the "true ribs" or on the iliac, The abdomen can be tightened with an appropriate pressure that generates a constant tension in the longitudinal direction.

Further, ribs clamping band 2A winding band 2, since "true ribs" which is the first to have never wound on the seventh rib 4 ₁ -2 _7, band wound that swells upward lungs before the intake 2 does not interfere and does not cause suffocation.

The thickness t of the wrapping band 2 is defined as the lying floor surface (the flat surface of the bedding 10) and the user when the user who wraps the wrapping band 2 around the body lies on the bedding 10 such as a bed in the supine position. seventh thoracic 5 ₇ dorsal near its thickness t as depression winding band 2 wrapped around the barrel fill occurs between around dorsal sacral 7 is set in. That is, assuming that the number of windings to be wound around the back side of the roll pillow is n, and the thickness t of the winding band 2 to be wound becomes a thickness t'that expands and contracts to some extent by being wound while generating tension in the longitudinal direction. the thickness nt in the stacking direction of the back side of the winding band 2 wrapped around part 'is the depth of the recess occurs between around dorsal dorsal and around the sacrum 7 of the seventh thoracic 5 ₇ supine user The thickness t and the longitudinal width L of the winding band 2 are set so as to be substantially equal to each other.

In the present embodiment, the wrapping band 2 having a thickness t such that the thickness t'on the back side when the wrapping band 2 is wrapped around the body is substantially equal to the recess δ on the back side of the user is used. As shown in FIG. 2, the longitudinal width L of the band 2 is set to a length in which the back side of the winding band 2 is a single layer (the number of turns n is 1).

As described above, the width W in the lateral direction, the width L in the longitudinal direction, and the thickness t of the wrapping band 2 set from the physical characteristics of the user have a certain allowable range. Therefore, for example, there are about three types. If you prepare about 9 types of wrapping bands 2 with different shapes, which are combinations of combinations with different widths W in the lateral direction and combinations with different widths L in the longitudinal direction and different thicknesses t, almost all users. Either can be applied to.

The pair of hook-and-loop fasteners 9a and 9b formed on the front and back surfaces of the elongated strip shape are locked to each other by bringing the opposing surfaces into close contact with each other, and are formed along one end of the back surface as shown in FIG. One hook-and-loop fastener 3a to be formed is formed in a vertically long rectangle along the end 2E which is the tail end portion of the winding end of the winding band 2, and the other hook-and-loop fastener 3b formed on the surface is the base end 2S at the beginning of winding. It is formed with a wide rectangular contour at a position approximately separated from the width in front of the user's abdomen. Therefore, when the winding band 2 is wound around the waist, the other surface fastener 3b provided on the outer peripheral surface of the lower layer winding band 2 opposes the one surface fastener 3a provided at the tail end of the winding end, and both of them By bringing the facing surfaces into close contact with each other, the winding band 2 is fixed around the waist in a state where tension is generated along the longitudinal direction.

By making the width of one surface fastener 3a along the winding direction (longitudinal direction) of the other surface fastener 3b wider, the locking position between the pair of surface fasteners 3a and 3b can be adjusted. There is. As a result, the same roll pillow 1 can be applied to users having different lengths around the abdomen, and the tension generated in the longitudinal direction of the wrapping band 2 is adjusted to adjust the abdominal pressure generated in the abdominal cavity. it can.

Next, a mounting method of winding and fixing the roll pillow 1 configured as described above around the body of the user will be described. When the roll pillow 1 is attached, the user stands up as shown in FIG. 2, exhales lightly, and keeps the abdomen slightly retracted. Subsequently, the lower edge 2L of the wrapping band 2 is aligned with the upper end 6U of the ilium, and the proximal end 2S is positioned near the front of the left flank with the abdomen slightly retracted.

After that, while holding the base end 2S, gently pull the wrapping band 2 to the right flank and the left flank that goes around through the back, and wrap the lower edge 2L parallel to the waistline along the upper end 6U of the ilium. Wrap from the position where it overlaps on 2S until the end 2E overlaps on the lower wrapping band 2 near the right flank, and in that state, the pair of surface fasteners 3a and 3b that oppose each other are brought into close contact with each other and locked. That is, in the present embodiment, the wrapping band 2 is double-wound at the front of the body and singly at the rear (back side).

When the wrapping band 2 is pulled and wrapped around the waist, the front surface and the back surface of the wrapping band 2, which are the fabrics, come into surface contact with each other, so that a high frictional force is obtained and the wrapping band 2 is tensioned along the longitudinal direction. It is hard to loosen even if it occurs.

By wrapping the wrapping band 2 around the waist while pulling it, tension is generated along the longitudinal direction of the rib tightening band 2A that is wrapped around the 12th rib 4 ₁₂ to the 10th rib 4 ₁₀ and the 12th rib 4 ₁₂ The 10th rib 4 ₁₀ bends slightly inward, and the outer surface of the rib tightening band 2A approaches a circular contour. Further, since tension is also generated along the longitudinal direction in the abdominal tightening band 2B integrally adjacent to the rib tightening band 2A, the 12th rib 4 ₁₂ to the 10th rib 4 ₁₀ are slightly inward in the abdomen. It is tightened to the extent that it bends, and an appropriate internal pressure that does not impose a burden on the internal organs is uniformly generated from the body surface toward the central axis of the abdomen.

With tension generated in the longitudinal direction, the end 2E of the wrapping band 2 wrapped around the waist is locked to the corresponding site in the lower layer, so that even if the user repeats natural breathing thereafter, the internal pressure in the abdominal cavity Is maintained.

Since the front surface and the back surface of the winding band 2 in which the pair of hook-and-loop fasteners 3a and 3b are locked and fixed around the waist are made of cloth, a high contact pressure is generated as described above. The upper edge 2U and the lower edge 2L sink inward of the torso (toward the central axis of the torso) from the relatively stable ribs 4 and the upper end 6U of the ilium, so that they do not loosen in the longitudinal direction. It is hard to shift the position.

However, if the wrapping band 2 loosens from the state in which the user is standing to lying on the bedding 10, the wrapping band 2 is gently wrapped around the waist in the standing state and temporarily fixed, and then the supine position lying on the bedding 10 is performed. Then, with the user exhaling and retracting his / her stomach, the end 2E of the wrapping band 2 may be pulled to generate a predetermined tension, and then the pair of hook-and-loop fasteners 3a and 3b may be locked.

If the user feels that the tightening is tight, the locking position between the pair of hook-and-loop fasteners 3a and 3b may be shifted so as to reduce the tension generated in the winding band 2.

In the method of attaching the roll pillow 1 described above, since the front surface and the back surface of the tightening band 2 are formed of cloth, the roll pillow 1 expands and contracts by a certain amount in the thickness direction, and even if the user's body surface and clothing have some irregularities. , Does not appear on the outer surface of the tightening band 2. Further, the steps appearing on the outer surface of the wrapping band 2 due to the difference in the number of layers at the positions of the base end 2S and the end end 2E of the wrapping band 2 are both on the front side of the body portion, and they roll over between the supine position and the lateral decubitus position. Since it does not appear on the outer surface of the wrapping band 2 in contact with the lying bed surface, the step does not hinder turning over.

Further, since the pair of hook-and-loop fasteners 3a and 3b that lock the end 2E to the corresponding portion are on the front side of the body portion, the user himself / herself can close the pair of hook-and-loop fasteners 3a and 3b and lock them. ..

Next, the action and effect when the roll pillow 1 is attached around the body will be described.
1. 1. Prevention of low back pain and relief of symptoms when low back pain occurs

By uniformly tightening the circumference of the abdomen with the abdominal tightening band 2B, the intra-abdominal pressure is increased to an appropriate pressure that does not impose a burden on the internal organs, and the pelvic pressure below the abdominal pressure is also indirectly increased. As a result, the organs in the abdominal cavity and the superficial muscles such as the rectus abdominis and oblique muscles are also stabilized.

Back pain often occurs in the vicinity of the lower lumbar spine of the fourth lumbar vertebra 8 ₄ or 5 lumbar 8 _5. This is the fifth lumbar vertebra 8 ₅ from the fourth lumbar vertebra 8 ₄ to bend, especially sudden lumbar of lordosis, slippery forward, there shearing force is likely because it takes burden on the disc near occurred in ing. By uniformly tightening it from the surrounding abdominal Abdominal clamping band 2B roll pillow 1, the lower lumbar 8 such as the fourth lumbar vertebra and the fifth lumbar vertebra _4, 8 ₅ and the first lumbar vertebra 8 ₁ and the second lumbar vertebra 8 ₂ including upper lumbar 8 _{1, 8 2} and, takes uniformly intra-abdominal pressure from the surrounding, so it acts to align in a uniaxial lower lumbar ₈ 4, _{8 5} slippery forward upper lumbar ₈ 1, _{8 2,} lower lumbar 8 _{4, 8 5} shear force does not work on. Therefore, not burdened the lower lumbar vertebrae 8 _4, 8 ₅ near the disc, back pain does not occur.

Further, with respect to the lower lumbar vertebrae ₈ 4, _{8 5} is stable with respect to the coupling to rotation to the pelvis, unstable upper lumbar ₈₁ with respect to rotation, _{8 2} of instability lower lumbar ₈ 4, 8 While ₅ is transmitted to stimulate the nerves in the vicinity of the lower lumbar spine 8 _4, 8 ₅ back pain is generated, the intra-abdominal pressure is applied to uniformly around the upper lumbar 8 _1, 8 _2, upper lumbar 8 _1, 8 ₂ because instability is reduced, also reduced back pain caused by upper lumbar 8 _1, 8 ₂ instabilities.

2. Promotion of turning over between the supine and lateral positions.

(1) turn between supine and lateral position bedtime usually begins rotation bending the legs, the torque of turn direction generated in the legs, the pelvis and the lower lumbar 8 _4, 8 ₅ and the upper lumbar 8 _1, 8 ₂ is transmitted to the rib cage consisting thoracic 5 and ribs 4 through the entire body portion is rotated in turn direction. The legs and pelvis and lower lumbar 8 _4, 8 ₅ are connected, but rotation is stable, if not the roll mounted pillow 1, rotation of the upper lumbar vertebrae _81, 82 to 12 thoracic 5 ₁₂ It is unstable, and the torque generated in the legs is attenuated in this unstable part and is difficult to be transmitted to the pelvis, so I used the force to turn over while lifting the waist and shoulders, or to be half awake.

According to this embodiment, the evenly tightened convoluted upper lumbar 8 ₁ is an unstable _moiety, from 8 ₂ to 12 thoracic 5 ₁₂ from the surroundings by the winding band 2, to stabilize the rotation unites Therefore, the torque in the turning direction is transmitted to the thorax without being attenuated.

Furthermore, the chest formed by the thorax and the buttocks formed by the pelvis are relatively fixed masses, whereas the abdomen, which acts as a junction connecting the chest and buttocks, is flexible, so that the legs and buttocks are formed. The rolling torque transmitted to the chest is absorbed by the soft abdomen and is not transmitted to the chest. However, according to the present embodiment, since the entire abdomen is tightened and hardened from the surroundings by the abdominal tightening band 2B, the torque in the turning direction is transmitted to the thorax without being attenuated even in the entire abdomen.

Therefore, even if the leg rotates only by applying a light force, the rotational energy is transmitted to the thorax without being attenuated by the flexion of the lumbar spine or the abdomen, and the body is smoothly rotated to turn over. Can be done.

(2) As a result of analyzing the rolling motion of a large number of subjects, the inventor of the present application found that the central axis of mechanical rotation inside the torso defined by the body surface at the torso of the body is the sternum stalk in the standing position. It is defined by a straight line connecting the center of the sternum, which is the midpoint of the 7th cervical spine, and the center of the pelvis, which is the intersection of the diagonal lines of the quadrilateral connecting the left and right superior anterior iliac spines and the left and right superior posterior iliac spines. It is the central axis of the body, and it has been found that smooth turning is performed when the central axis of the body is parallel to the lying floor surface (plane of the bedding 10) in both the supine position and the lateral decubitus position. According to the present embodiment, since the wrapping band 2 tightens the body surface around the torso with a uniform force from the surroundings, the twelfth ribs 4 _{12 which} are relatively easy to bend bend slightly inward of the torso and around the abdomen. The contour of the flat oval shape around the abdomen is corrected so as to approach a circle, and the outer peripheral surface of the wrapping band 2 wrapped around the body approaches the cylindrical body around the central axis of the body parallel to the plane of the bedding 10. ..

In particular, in the lateral decubitus position, the spine from the lower thoracic vertebra 5 to the lumbar vertebra 8 bends in the direction of the bedding 10, and the abdomen around it also hangs in the direction of the bedding 10, but the circumference of the abdomen is tightened by the wrapping band 2. The central axis of the abdomen, defined by the spine of the abdomen and the body surface of the torso, is corrected to be parallel to the lying bed surface (the plane of the bedding 10).

Furthermore, in the supine position, as shown in FIG. 4, the thickness of the lamination direction of the back side of the winding band 2 wrapped around the body portion, the back of the back side near the sacrum 7 of the seventh thoracic 5 ₇ of the user approximately equal to the recess produced between the near side, in lateral position, as shown in FIG. 6, the thickness of the lamination direction of the winding band 2, lateral position of the user of the eighth rib 4 ₈ to ninth rib 4 ₉ Since the dent that occurs between the vicinity and the vicinity of the large trouser 9 is filled, the outer peripheral surface of the wrapping band 2 always fills the dent around the abdomen during turning over between the supine position and the lateral decubitus position. It is in contact with a flat surface. Therefore, as shown in FIGS. 5 and 7, the outer peripheral surface of the wrapping band 2 approaching the cylindrical body as described above guides the abdomen where the center of gravity of the entire body is present so as to roll on the surface of the bedding 10. Acts as a drum 21.

Further, since the outer surface of the wrapping band 2 that rolls and contacts the surface of the bedding 10 is a cloth, when the surface of the bedding 10 is a cloth such as a bed or a futon, the bedding 10 comes into contact with each other with a high frictional force. The outer peripheral surface of the band 2 slides on the surface of the bedding 10, and there is no loss of rotational energy in the turning direction.

Further, as described above, the chest formed by the thorax and the buttocks formed by the pelvis are relatively fixed masses, and as shown in FIGS. 5 and 7, a chest drum that rolls on the surface of the bedding 10. 20. Since it acts as a buttock drum 22, the abdominal drum 21 becomes a junction that connects the chest drum 20 and the buttock drum 22, and the entire body is made into an integral cylindrical body so that the entire body is rolled on the bedding 10. I will guide you to.

(3) Therefore, the action of (1) that the person can turn over with a light force of unconsciousness and the action of (2) that the wrapping band 2 guides the entire body to roll on the bedding 10 are combined. By collaborating, it is possible to turn over smoothly, and unconsciously turn over while sleeping, blood, lymph, and joint fluid circulate, and thermoregulation and metabolism are promoted.

In the above-described embodiment, the tail end portion of the wrapping band 2 is provided with a pair of hook-and-loop fasteners 3a and 3b at the end 2E which is the tail end portion and the corresponding portion to form a locking portion. It may be locked by other methods such as engaging the hook.

Furthermore, if the rib clamping band 2A is wound on at least a 10 rib _{4 10,} the upper edge 2U winding band 2, even the tenth rib _{4 10} anywhere between the eighth rib _{4 8} Good.

The present invention is suitable for a roll pillow and a method of wearing a roll pillow that the user wraps around the waist while sleeping.
