Description

  The present invention relates to a cushion suitable for posture recovery training for disabled people, elderly people, etc. and capable of holding a sitting posture comfortably for a long time.

  Conventionally, a large number of cushions using expanded polystyrene beads as a filler in a bag body exist. For example, a granular foamed resin body of 1 mm or less of fine particle beads made of expanded polystyrene is filled in a stretchable bag of one bag, and this bag is accommodated in a cushion cover. However, it is easy for the user to maintain the target posture because the bead of the granular material filled by the load of the user is easily moved inside the bag and sometimes the bag itself may be stretched too much. Rather, it was not always enough to keep the body comfortable in the desired posture position.

  Therefore, a cushion has been developed in which a part of the cushion cover is made of a stretchable material and the other surface is made of a non-stretchable material. For example, Patent Document 1 discloses a cylindrical bead cushion sofa in which the upper surface of the cushion cover is made stretchable using spandex and the other surface is made of a non-stretchable material made of a vinyl chloride sheet. Further, Patent Document 2 discloses a cushion in which one surface of a flat surface or a bottom surface is made of a stretchable spandex fabric made of polyurethane elastic fiber, and the other surface is made non-stretchable.

Japanese Patent Laid-Open No. 2000-93260 JP, 2009-219558, A

  Certainly, the combination of these stretchable and non-stretchable material cushions the movement of the granular foam resin inside with the non-stretchable material of the other surface by limiting the stretchable surface to a part of the surface. Since it can be suppressed, the tendency of the beads supporting the body to flow so as to escape from side to side and the attitude change is somewhat reduced.

  However, the size of the cushion is generally about 60 cm square and about 15 to 30 cm in thickness, so the weight of the body is greatly influenced when it is put on the body, and the particulate foamed resin is small. Move without.

  However, even if it is known that it sinks in advance, wrinkles are likely to occur between the expected sinking and the actual sinking, and it may be necessary to re-set several times to obtain the desired posture position. . In addition, once the body was leaned, it was difficult to correct the holding position to a desired posture position in a lying posture.

  And even if it is a healthy person, it may be difficult to easily change the sitting posture when it is deeply embedded so as to be buried in fine bead-like particles during use. When the particles are fine foamed resin bodies of 1 mm or less, the particles are easily moved each time a load is applied, and a force is hardly applied.

  Then, in the case of physically handicapped persons and elderly people, it may not be easy to sit in the first place, and the shape of the cushion is likely to change due to load even if the support of an attendant is obtained and seated at the time of seating. However, it was not always possible to sink to the expected position, it was not easy to achieve the desired posture, and it was extremely difficult to adjust to the desired position after sitting. Therefore, a cushion that can be easily adjusted to a desired posture after sitting is desired.

  By the way, there are many disabled people and elderly people who are working on daily rehab with the condition that their muscles are getting stiff while their posture is distorted. It is not easy for these persons to fit their body to the ideal posture provided by the device, even if they sit on the device in a comfortable sitting position for the general public. Being forced, it is difficult to get out of tension by sitting.

  Therefore, using a bead cushion made of granular foam resin, which has room to support the body appropriately according to the posture of the person, can be used to provide the desired posture in which the person can relax comfortably. It can be expected to be easier to relax. Therefore, it is considered to be useful in rehabilitation for posture recovery.

  In order to expand the working range of joints in rehabilitation, it is desirable for the seat occupant to first release the muscle tension by allowing the body to be released from tension and forming a comfortable seating posture. In this way, if it is possible to hold the posture released from tension for a while, by sitting down, the body rests, and the muscles released from tension can expand and contract. Therefore, joints that have been difficult to move can gradually expand their working range due to relaxation of surrounding muscles, which can lead to effective rehabilitation training. Therefore, what can be provided as a simple device for relieving the tension of stiff muscles is desired.

  Furthermore, if the working range of the seat occupant's joint is expanded by sitting, the position of the sitting posture changes gradually by being released from the tension state, so that it is easy to be released from the tension state every time you sit down. Attitude is different. Therefore, it is also desired that the position can be finely adjusted so as to be a comfortable posture position for a seated person, and the posture can be easily easily readjusted.

  By the way, the ideal relaxed posture at the time of general sitting including the healthy person is not to reproduce the posture in which the spine is stretched as in the upright state. In the upright posture, the two muscles of the "Impostomus group" on the lower abdomen side and the "tendon muscle group" on the buttock side act as antagonistic muscles, so tensions that pull each other across the unstable joint of the hip joint The pelvis is held firmly and firmly in a “stand-up position” with the ischium located directly below, but when a person takes a sitting position and the hip joint bends nearly 90 degrees, In the case of the iliopsoas muscle group, the positions of the lumbar spine and the femur where the muscles are attached become close, and the stretched muscles become loose, so the tension becomes weak. On the other hand, since the “gluteusnum group” on the buttocks side is stretched from the pelvis to the femur around the hip joint as it goes around the outer side, tension is strongly applied. On the contrary, since a large load is applied to the ischium and a partial load is applied to a part of the buttocks in contact with the seat surface, it does not become relaxed even when the upright posture is reproduced.

  Rather, the relaxed sitting position of the skeletal and muscle tensions is a slightly reclining back-backed position. In the sitting position, when these antagonist muscles supporting the pelvis try to balance tension, the pelvis, which is located at the lower position in the standing position and is in the "standing position" vertically, pushes the sciatic forward. As you tilt, you will be in the "tilted position". In the sitting position, it acts as a muscle tension that causes the pelvis to tilt around the hip joint.

  As described above, since the pelvis serving as the foundation is tilted, it is necessary to have an extra muscular strength to maintain the posture in which the lumbar spine and the like located above the spine extend straight in a S-shape. . And, even in the case of a healthy person or a disabled person, when sitting down relaxedly, the pelvis tilts naturally, and the back is rounded accordingly.

  Therefore, when sitting on a cushion made of foam granules, the general relaxed posture is a posture such that the knees are raised and the back is rounded while the entire back is deposited on the cushion while lowering the waist. Become. A cushion that can easily form and hold such a posture is desired.

  However, in the cushioning process, since the bead-like granular foamed resin body in the inner bag flows internally in the seating process during the seating process, the posture is likely to shake during seating, and it is difficult to stabilize the body until it is completely seated. . Then, it may be difficult for the disabled and elderly people to sit on a thick cushion having a cylindrical or rectangular shape, and it is difficult to sit down. In some cases, it may not be possible to take a sitting position. Therefore, there is also a demand for a structure in which the sitting motion is easy to take so that a disabled person or the like can easily sit in a relaxed position.

  From the above, the problem to be solved by the present invention is a cushion which can be comfortably seated for a long time by supporting the load of the body appropriately and supporting it, and it is easy to take a sitting motion of the sitting posture, and To provide a cushion that can be easily adjusted so as to form a desired posture and support and hold the desired posture even after sitting, and a sitting posture suitable for posture recovery training for disabled people and elderly people It is to provide a cushion that is easy to adjust and sit on.

  A first means for solving the problems of the present invention is to form an outer bag body by combining a seating surface and a bottom surface made of an elastic material with a side surface made of a non-elastic material, and the side surface of the outer bag body A cushion characterized in that an inner bag portion made of a stretchable material filled with a shock absorbing material made of a granular foam resin body is housed inside a cushion cover in which a restraint band is circulated in a part of the is there.

  A second means of the present invention is characterized in that the restraint band is made of a non-stretchable material whose band length can be variably adjusted, and at least two places of the outer periphery of the outer bag body are anchored. It is a cushion as described in a 1st means.

Third means of the present invention, the restraining bands, a portion of the constraining band comprises a sewing portion which is sewn to the side surface of the outer bag, the tip of the band extending from the sewing area It is those which arranged band side as mooring unit tethered to the side surface of the outer bag in the circumferential direction, wherein, wherein, the band length can be variably adjusted between the anchoring portion and the stitched portion It is a cushion of Claim 1 or Claim 2.

According to a fourth means of the present invention, the restraint band is one in which a part of the band is branched into a plurality of parts, and a part of the branched parts is arranged in parallel so as to be separated in parallel to the side surface of the outer bag body A cushion according to claim 3, characterized in that it is sewn in the longitudinal direction.

Fifth means of the present invention, the constraining band, the sewn portion is either from the inner surface side of the outer bag side third or 4, characterized in that it is the outer bag sides and sewing the It is a cushion as described in a means of. That is, the restraint band is inserted into the gap between the outer bag body and the inner bag from the hole opened in the outer bag body side surface, and the band portion inserted into the gap is outside from the inner surface side of the outer bag body side. the bag is sewn on the side.

  According to a sixth means of the present invention, any one of the first to fifth aspects is characterized in that a plurality of the restraining bands are arranged, and each restraining band is circulated around a part of the outer bag body side surface. It is a cushion as described in or means 1.

A seventh means of the present invention comprises a granular foamed resin body inside a cushion cover formed in an outer bag body by combining a seating surface and a bottom surface made of an elastic material and a side surface made of a non-elastic material. A cushion that accommodates an inner bag portion made of a stretchable material filled with a shock absorbing material, and the outer bag body and a pullout belt in which the inner side and the both end portions of the opposite left and right sides of the outer bag body are sewn The cushion is characterized in that it is disposed between the inner bag portion and the center portion of the drawer belt is exposed so as to be extractable from the opening of the side surface of the outer bag body.

That is, the left and right ends of the lead belt, respectively the inner side of the side surface of the outer bag are sewn, the pull-out belt is arranged between the outer bag body and the inner bag portion, the central portion of the lead belt Is exposed to the outside from the opening provided on the side surface of the outer bag body, and the drawer belt is used to be pulled out further while seated on the cushion. For example, when the exposed portion of the central portion of the drawer belt is the side surface of the head of the seated person and provided on the left and right sewing portions of the side of the outer bag and the left and right sides of the buttocks of the seated person, the central portion of the drawer belt is pulled When it is pulled out, it flows in the direction in which the beads of the surrounding granular foam resin body are pulled out, so that the upper body of the seated person is lifted up so as to be pulled up, and the beads follow the line of the seated body It will be held. And since the state as it is is hold | maintained without returning by the load of a seating person even if it does not fix a drawer belt, arrangement | positioning of the bead along a seating person's comfortable attitude | position can be comfortably formed.

Eighth means of the invention, arranged restraint band band length on the side face of the outer bag is made of a variable adjustable non elastic material, sewn to the side surface part of said restraining bands sewn It can be variably adjusted band length between the end that is anchored with the sewn portion a band portion which is not moored to the wall part is a cushion according to the seventh means, characterized in.

  According to a ninth means of the present invention, the outer bag body is a surface in which a part of the seating surface is inclined downward, and a lower end side outer edge portion of the inclined surface is for supporting an upper limb outside the outer bag body. It is a cushion as described in any one of the means of 1st-8th characterized by protruding and providing the leg stand which consists of a support part which supports a mounting part and a mounting part.

  According to a tenth means of the present invention, the mounting portion of the footrest has one end joined with the lower end side outer edge of the outer bag body, and a posture in which the joint portion is horizontally lowered and a posture raised obliquely According to a ninth means characterized in that the movable mounting portion which can be positioned up and down, and the mounting portion in a state of being raised obliquely is supported by a support portion which supports from below, so as to be adjustable in angle. It is a cushion of a statement.

  The eleventh means of the present invention is characterized in that the inner bag portion is one in which two inner bags, a large inner bag and a small inner bag, are filled with a shock absorbing material consisting of a particulate foamed resin body. A cushion according to any of the eighth means.

  According to the present invention, since a part of the outer bag body is restrained by the restraining band and is difficult to be extended, the side shape is easily maintained, and the flow of the filled granular foam resin body is suppressed, and seating of the seated person Since the shape of the cushion easily conforms to the state, the simple restraint band suppresses the sinking due to the load of the seat occupant, the posture is less likely to collapse, and the sitting motion of the desired seating posture is easy to take. It becomes easy to disperse and support the load properly, and it becomes possible to sit comfortably for a long time.

  In addition, the restraint band is looped around a part of the side circumference, and at least two points on the side circumference are moored and the length of the restraint band between them is made variable so that a part of the side circumference can be tightened by adjustment. In addition to being difficult, the outer bag body can be positively restrained as needed by tightening it, and a part of the side can be tightened so that the shape can be made less likely to collapse in the state of being previously tightened from before seating. Not only the desired posture can be easily obtained, but after the seating, the length of the restraint band is pulled and contracted to adjust the length of the restraint band, and a part of the side surface of the outer pouch body is a restraint band around the outer periphery of the outer pouch body. Because it is possible to fix the shape of the cushion in the sitting state, it is not only that it is not easy to swell, but also after sitting the posture that has been changed by the load of the user Even it is easy to continue to further modified to a desired position.

Furthermore, when a part of the restraint band is sewn to a part of the side surface, the strength of a part of the side surface is increased and the shape of the sewn peripheral portion is less likely to collapse, so the shape change under load Is reduced.

Furthermore, in a sewing area is central, the case in which the anchoring portion to the left and right two positions are respectively provided on the left and right sides of the outer bag wall part so as to sandwich the central sewn section, both ends of the band, respectively Since it is moored to the mooring part, the band length can be variably adjusted between the end of the sewn part and the mooring part at these left and right positions. When it shrinks, a restraining band circling a part of the side of the outer bag will tighten the side of the outer bag, but the central reinforced seam will be integral with the surrounding outer bag. Since the outer bag is shrunk in the vicinity of the portion where the left and right length fluctuates, the circumference of the sewn part moves integrally as a face to the center side of the cushion because it is pressed as a face to the center side of the cushion. These movements generally result in granular foam inside the cushion It becomes possible to move the fat body to push large around, can be part of the easy to shape correction to a more bulky state of the outer bag.

Further, when a part of the restraint band is branched to arrange a plurality of bands in parallel so as to be separated in parallel, and a part of the branch part is sewn on the side surface of the outer bag body. The band portion is sewed on a part of the side surface of the outer bag body with a width in the height direction. On the other hand, since it is one band-like band between the mooring part and the sewing part, when the length of this part is adjusted and contracted, the part which is branched into a plurality is drawn by tightening one band-like band. It is convenient in that it can be greatly varied by one adjustment.

Then, since the sewn portion of the band branched in parallel to the plurality of sewn portions and the periphery thereof become large surfaces and move toward the cushion center while being pulled up so as to push up the entire circumference, for example, In the case of a configuration in which the left and right mooring points are provided and the central part is branched, the entire length of the sewn part of the multiple branched band parts is made wider by shrinking the left and right lengths of one band respectively. As a surface, it is strongly pressed toward the inside of the cushion, and a wide range of restraining force is applied not only to the sewn portion of the band but also to the periphery widely, and it can be easily realized that the cushion shape is greatly varied. Become. And since the movement amount of the granular foam resin body by the length adjustment of the band becomes large, the seat occupant can easily make a large adjustment by the adjustment of one band, so the cushion thickness and the height can be more easily sufficient. It will be easier to secure

And since the restraint band inserted into the gap between the inner bag and the hole from the hole opened on the side of the outer bag is sewed to the inside of the side of the outer bag, it is between the mooring part of the band and the opening hole Only the band portion of is the exposed portion of the restraint band in the cushion cover. Then, not only sewed portion of the constraining band is provided smooth sides less caught by being arranged on the inner side, between the sewn part and the opening and does not restrain the outer bag body side, the outer Since it can be greatly tightened without being obstructed by the fabric on the side of the bag, a greater change in posture can be realized.

  In addition, if a plurality of restraint bands are provided to a part of the side surface of the outer bag, the tightening length can be adjusted for each restraint band. The posture adjustment can be performed more finely by changing the other part from the other part, and the posture that can be easily applied to a seated person can be formed more simply and appropriately.

  When the draw-out belt is disposed between the outer bag and the inner bag, both ends of the belt are fixed to the side of the outer bag, and the central portion of the belt is exposed to the outside of the outer bag so that it can be pulled out. The bead of granular foam resin inside is moved following the pulled-out belt. Therefore, when the user pulls this out in the sitting state, the bead around the seated person moves so as to fill the surrounding gap so as to be in line with the posture of the seated person being leaned back and supported. In addition, for example, when the belt is pulled out to the head side, the bead moves from the waist toward the head, so that the upper body of the seater can be lifted up so that the head side becomes high. It becomes possible to easily realize the formation of a comfortable posture, such as easy formation of the state. And, even if the drawer belt is not fixed, it is kept as it is without returning by the load of the seated person, so that the arrangement of the beads along the comfortable posture of the seated person can be kept comfortably formed. .

  Furthermore, when the restraint band and the draw-out belt are combined, the draw-out belt is pulled out after sitting, and the granular foamed resin is driven to move along with the posture, which makes it easy to realize the support along the posture of the seated person At the same time, by further adjusting the length of the restraining band and restraining, since the shape of the cushion cover is held firmly by restraining the shape of the side surface, the posture once formed is held without being broken It will be easier to do so, and the attitude will continue to be supported more stably, so it will be possible to realize the support that was found in a comfortable attitude and hold it for a long time.

  In addition, even if the seated person's posture is not stable due to the muscles stiffening, etc. and can not stretch back and back and can not take the same posture as a healthy person, the side before and after sitting By adjusting the length of the restraining band, it is possible to actively change the shape of the cushion so that it can be supported along the posture of the seated occupant, making it possible for persons with physical disabilities. Even if it is, it can be seated by the cushion of the present invention, and the tension can be relieved, so that the rigid tension state is relaxed and becomes easy to move. And since it is a simply adjustable restraint band when making it sit on the cushion of the present invention repeatedly, the position of a restraint band is adjusted each time, and the posture of the state where the tense muscle of a seating person can be relieved is appropriate Because the seat occupant's body is kept in a relaxed state repeatedly, and when the rehabilitation that gradually improves the range of movement is tried, it is extremely easy to work, and the body posture is relaxed. It is possible to provide a cushion with high compliance.

  Furthermore, in the cushion provided with the outer bag body having a shape in which a part of the seating surface is inclined downward, and the footrest protruding from the lower end of this inclination, the back surface of the seated person is obliquely sloped Since the upper limbs are placed on the pedestal of the footrest while being supported so as to be in contact with the surface, the granular foam resin body in the cushion disperses the load on the upper body of the seat occupant As it is supported, the upper thigh side of the upper limb is also supported by the footrest, so it can sit in a bent shape with its waist bent, and the ischium of the seated person is pushed forward and tilted, lower iliopsoas muscle group in lower abdomen Since the two muscles of the gluteus muscle group on the buttock side can be balanced, it is possible to easily form a relaxed comfortable posture.

  Furthermore, the seat occupant can sit in a state where the placement portion of the footrest is laid horizontally by freely raising and lowering from the state where the placement portion of the leg is laid down horizontally to a state where the placement portion of the footrest is raised. It becomes easy to take a desired sitting posture by adjusting and fixing the inclination angle of the footrest by the support portion so that the mounting portion is obliquely raised from the horizontal position while the C is placed. Therefore, after making a person with a disability or elderly person sit at a height close to the horizontal floor surface, lift the upper leg diagonally from the bottom so that the back side of the knee becomes higher to the state where the upper limbs are placed on the placement portion. Since it can be done, it can be safely and stably seated on the cushion of the present invention as well as healthy people.

  Also, by dividing the inner bag part into two inner bags, the large inner bag and the small inner bag, the movement of the cushioning material made of the particulate foamed resin body filled in the inner bag part is restricted to each inner bag. Since the inner bags are pressed against each other internally, the flow of the particulate foamed resin body generated by the load applied from the seated occupant's body is suppressed. For example, when the head and body of a seated person are seated on the large inner bag so that the legs are positioned on the small inner bag, the large inner bag and the small inner bag are in contact with each other. The sitting position can be maintained without excessively sinking the lumbar portion located on the boundary of the seat.

  Furthermore, by tightening the restraint bands of the outer bag on the head side and the leg side, it is possible to form and maintain an appropriate comfortable state during or after sitting, so the body was relaxed. It will be easy to realize the state. In particular, since there are two types of inner bags of different sizes, the bag with a large amount of filler material is bulked up in response to the tightening of the restraining band and the height can be easily obtained. It becomes easy to form the shape of making it high. Then, while sitting on a cushion filled with foam particles that are usually easy to flow, the head side is particularly high while the knee side is higher than the waist while leaving the entire back on the cushion as if lowering the waist. It is also easy to easily take a posture in which the back is rounded, that is, a general relaxed comfortable seating posture, because it is easy to position it high. Then, it becomes a cushion suitable for a seated person continuing to sit comfortably for a long time.

It is a perspective view which shows the cushion of Embodiment 1 of this invention, Although large and small two inner bag parts were described above, this is accommodated in the outer bag body shown below, and it becomes a cushion. It is the figure which showed a mode that the shape of cushion of Embodiment 1 of this invention was adjusted using a restraint band. An upper stage (a) is a figure before adjustment, and a middle stage (b) shows a mode after pulling a cuff part of a restraint band and adjusting shape, and a lower stage (c) adjusted a length of a restraint band It is a figure which shows a mode that it seated in the state. It is a front view of the cushion of Embodiment 1 of this invention. The left is the head side, and the right is the seating direction of the leg. It is a perspective view of the cushion of Embodiment 2 of this invention. It is the figure which assembled the base of the cushion of Embodiment 2 of this invention. It is a top plan view of the cushion of Embodiment 2 of this invention. It is a front view of the cushion of Embodiment 2 of this invention. Head toward the head, the right is a footrest, the footrest is in a state of being folded horizontally. It is the figure which showed sequentially a mode that it was seated on the cushion of Embodiment 2 of this invention. (A) shows a state where the leg stand is seated horizontally, (b) shows a state where the leg stand is raised obliquely, and (c) shows a state where the restraint band and the pullout belt are adjusted and seated. It is a perspective view of the cushion of Embodiment 3 of this invention.

A mode for carrying out the present invention will be described using drawings and the like as appropriate.
First, the cushion 1 of the present invention has an elastic inner bag portion 7 inside the outer bag body 2, and the inner bag of the inner bag portion has a bead-like particle diameter as the granular foamed resin body 8 of the filler. Is filled with a small amount of expanded polystyrene resin. The particle diameter of the beads may be a particle diameter of several millimeters or less, but from the viewpoint of flowability and body pressure dispersion, for example, particles having a particle diameter of 1 mm or less, particularly 0.5 mm or less are desirable. Then, the inner bag of the inner bag portion 7 made of a stretchable material filled with a foamed polystyrene resin having a small bead-like particle diameter as a filler is an outer bag formed of a stretchable surface and a non-stretchable side surface. It will be stored in the body 2 and one or more restraint bands 11 will be further circulated on the non-contractile side surface 5.

  Next, it is desirable that the inner bag of the inner bag portion 7 be a stretchable bag body from the viewpoint of followability. The inner bag is filled with the granular foamed resin body 8 having the same amount or more as the normal volume of the outer bag body 2 of the cover and then sealed by closing a fastener or the like. By increasing the filling amount in this manner, it is easy to suppress the movement that flows too much, and it becomes easy to avoid depression of the cushioning property. Then, the shape of the side surface 5 restrained by the band 11 is easily maintained, and the flow of the filled granular foamed resin body 8 is suppressed, so that the sinking by the load of the seated person is suppressed and the posture is less likely to collapse .

  The outer bag body 2 has, for example, a rectangular solid shape (full length 1200 mm × width 600 mm × height 450 mm) or a cylindrical shape, and the upper flat seating surface 3 has the bottom surface 4 as a lower base, and these surfaces use an elastic material. Shall be As the stretchable material, for example, a material having stretchability secured by using polyurethane elastic fiber yarn such as spandex can be used. In addition, by using a structure in which a two-layered knit fabric called "dampole knit" is joined with a middle thread, it may be structurally able to obtain stretchability, and further, for a middle thread of a cardboard knit fiber, etc. Spandex yarns may be combined to enhance elasticity. If a knitted fabric such as a cardboard knit consisting of such a two-layered knitted fabric is used, it becomes a strong and stretchable material. Therefore, when applied to the present invention, the air permeability of the seating surface 3 and the bottom surface 4 Since durability can be ensured, it is particularly suitable because it is suitable for long-time seating. The elastic seating surface 3 and the bottom surface 4 may be made of the same material, or may be used by replacing the upper and lower surfaces. The outer bag body is not limited to a rectangular parallelepiped, and may have a trapezoidal shape or a teardrop shape having a wide lateral width on the head side and a narrow leg side in plan view from above. By making the head side larger, it becomes easy to increase the thickness, and the room for posture adjustment on the body side becomes large.

  On the other hand, general thick cloth, plastic resin sheet such as vinyl chloride resin, rubber sheet, leather, artificial leather etc. can be applied to the non-stretchable material of the side part 5, but strength, air permeability and heat dissipation In view of the above, thick and durable fabrics such as canvas are particularly suitable.

  Further, the restraining band 11 is made of a non-stretchable band or string, and in particular, a strong and hard to stretch nylon or polypropylene band belt or the like is preferable. The restraint band 11 is turned around a part of the side surface 5 of the outer bag body 2 so that the side surface 5 around the restraint band can be pushed out and spread out by the load of the seat occupant, so that the posture change is suppressed. By arranging the non-stretchable restraint band 11 on the side surface 5 in the form of a belt, the extension of the side surface 5 around the restraint band 11 can be restrained. Then, since it becomes lightweight compared with the case where the side surface 5 whole is firmly restrained by a thick member, it becomes easy to handle. In addition, using the restraining band 11 is more economical than using all of the material of the entire side surface 5 to be replaced with a thick and strong one.

  And in the case of the 2nd means, after making the restraint band 11 run around a part of the side 5, at least two points of the side 5 are moored and the length of the band between them is made variable, The band length is reduced accordingly. By constraining part of the side surface 5 with the band 11, in addition to the side of the outer bag body around the restraining band 11 flowing under the load of the seated person and being difficult to spread outward, the band is further stretched after seating. By adjusting the length of the restraining band 11 by carrying out, etc., it becomes possible to easily tighten a part of the outer bag body side surface 5 with the restraining band 11 wrapped around the outer bag body side surface 5. By positively fastening in this way, it is not only difficult to swell, but it is easy to further correct the posture, which has fluctuated due to the load of the user, to a desired position even after sitting. It has become.

The restraint band 11 is in the form of a belt (for example, made of propylene having a total length of 2200 mm and a width of 38 mm), and one end thereof is sewn on the side surface 5 of the outer bag body 2 to form a mooring part. A ring-shaped hook made of metal or plastic resin (for example, flat can, D-can, carabiner) sewed on the side, or a belt material of the same material as a ring, these are used as the anchoring portion 12 and passed through the belt And the other end of the belt of the folded restraint band is held by using a buckle, an adjuster or the like so that the length of the folded back can be adjusted and held. May be Since the length of the restraint band 11 can be freely adjusted by these buckles and the mooring part, the sitting posture can be positively adjusted.

And the restraint band 11 connects the belt divided into the belt of the part A on the sewing part side and the part B on the mooring part side via a buckle and distributes it in the side circumferential direction of the outer bag body 2 as a single restraint band. It is also possible to For example, the part A locks one end of the belt extending from the sewing part 14 to the buckle, while the part B uses the buckle side as the folded back part of the belt and the other end of the belt of the part B as the mooring part 12 The belt length of the restraint band 11 can be adjusted by adjusting the length on the part B side by sewing on the side surface 5 of 2 and inserting and folding back to the ring portion in the buckle, that is, the sewing portion 14 and the mooring portion The length between 12 may be adjustable.

Then, as in the above-mentioned third means, for example, the central portion of the restraining band 11 is sewn to a part of the side surface 5 of the outer bag body 2 to increase the strength of a part of the side surface 5 As well as being able to do this, it is possible to suppress the expansion of the periphery by pulling the periphery of the sewn portion 14 strongly inward by adjusting the band length. Specifically, when the outer bag body 2 is a rectangular solid, if one of the short sides of the upper plane is on the head side and the other is on the leg tip side, the side surface of the outer bag body 2 on the head side or the leg tip side A belt-like restraining band 11 circumferentially wound around the center of the belt is sewn about 30 to 80 cm over the longitudinal direction, and this is used as a central horizontal sewing portion 14 of the restraining band 11. The left and right bands extending from the central sewing portion 14 are engaged with the buckles, and the parts B of the mooring portion 12 provided on the left and right sides of the outer bag body 2 are sewn to the mooring portion 12 By adjusting the length between the end of the portion 14, the band length can be variably adjusted.

Then, first, the shape of the peripheral portion of the sewn portion 14 is unlikely to be deformed , and the shape change is reduced even if a load is applied. Then, when the band length is adjusted and the lengths of the left and right portions of the restraining band 11 are reduced, the restraining band 11 circulated around a part of the side 5 of the outer bag 2 tightens the side 5 of the outer bag 2 However, the central reinforced sewing portion 14 is pressed as a surface on the center side of the cushion 1 integrally with the surrounding outer bag body 2. The outer bag body 2 shrinks in response to the shrinkage of the belt in the vicinity of the varying portion of the belt length on the left and right, but the periphery of the sewn portion 14 integrally moves toward the center of the cushion as a surface. It is possible to easily move a part of the outer bag body 2 into a bulky state by moving the granular foamed resin body 8 inside the cushion 1 so as to push it up to the periphery.

By the way, the sewn portion 14 of the restraining band 11 sews the restraining band 11 to the canvas of the non-stretchable material which is the side surface 5 of the outer bag body 2, and the sewn portion 14 is surrounded according to the change of the band length. Can be moved following along with the outer bag body side surface 5. The sewn portion 14 is suitable if those are sewn large as the non-stretchable side 5 of the outer bag along the longitudinal direction of the restraining band 11, the other, 10 cm about sewing the end of the restraining band 11 It may be just worn . Then, when sewing the end, apply a non-stretchable canvas or the like to the inner surface side of the outer bag body around the sewing portion to reinforce the periphery and reinforce the restraining force. It is also good.

Furthermore, as in the fourth means, the restraint band 11 circumferentially turned around a part of the side surface of the outer bag body 2 is 1 between the vicinity of the left and right ends of the sewn portion 14 and the mooring portion 12 It is sewn to the side surface 5 of the outer bag body 2 so that a plurality of bands may be separated in parallel and separated at the central sewing portion 14 while forming a band-like band of a book Can. Band central portion, which is respectively horizontally sewn with branched into plural has a what is sewn spaced and parallel to different heights of the part of the side surface of the outer bag. Then, since there is one belt-like belt between the mooring portion 12 and the sewing portion 14, when adjusting and shrinking the band length of this portion, the left and right bands are tightened one by one, As a result, a plurality of parallel band central portions of the sewing portion 14 move to the central side of the cushion 1 while making the surface large and pushing up the periphery.

For example, the restraint band 11 is sewn horizontally approximately 25 to 50 cm horizontally so that the center height position is 10 cm and 32 cm on the side surface 5 of the rectangular outer bag body 1 having a height of 45 cm. . Bands of about 4 cm in width, and bands that are sewn in parallel horizontally and separated by about 20 cm will be stitched on the side.

Then, by shortening the left and right lengths of the restraining band 11, the whole of the plurality of belt sewn parts 14 is strongly compressed as a surface toward the inside of the cushion in a wider range by adjusting the length of one band. It will be. Since the sewn parts 14 separated from each other are pushed in the center direction as a surface, the restraining force to the contained inner bag part 7 is increased, and it becomes easy to greatly change the cushion shape near the sewn parts 14. For example, when there is a sewn portion 14 on the upper side of the top of the head of the seated person, the head of the granular foamed resin body 8 inside is pushed up greatly, and when the waist is low and the upper body is obliquely high, etc. By tightening the part to be held, it is possible to secure a sufficient cushion thickness and height on the head.

Incidentally, a band sewn portion 14 parallel with the so important that may compress as a surface, in addition to sewing the branched ahead, may be beginning to sewn from the portion that branches. It is possible to positively deform the shape by constraining the surrounding outer bag body so as to be rolled up while having the horizontal sewing part 14 separated, so that it is possible to reinforce the surface larger than the band itself without further reinforcing it. As it is finished, it can be realized with the minimum reinforcement.

As in the fifth means, the restraint band 11 is locked to the outside of the side surface of the outer bag body 2 by the mooring portion 12 and the outer bag body is inserted from the insertion hole opened in the side surface of the outer bag body 2. The band central portion 13 is inserted to the inner surface side of the outer bag body so as to pass through the gap between the inner surface of the inner bag 7 and the outer surface of the inner bag 7, and the band 11 is again from the other opening to the outer surface of the outer bag body 2. It may be arranged to be exposed. And since the inner surface of the side of the outer bag and the central portion of the band are sewed , there is no exposure of the band on the side of the outer bag of the sewn portion 14 and a smooth outer surface is provided. It becomes.

In addition, since the band can tighten the inner bag from the both ends of the sewn portion 14 to the opening without restraining the outer bag body 2, the unstretchable outer bag body 2 is not obstructed. By squeezing the inner bag directly to the body with a band, it is possible to restrain the flow and the posture movement of the particulate foamed resin body 8, and it is possible to exhibit a greater tightening effect.

  Further, as in the sixth means, when a plurality of restraint bands 11 circulated around a part of the side surface of the outer bag body 2 are arranged, the length adjustment can be appropriately made for each band, so Adjustment for each restraint band makes it easy to realize appropriate sitting comfort. As the arrangement of the plurality of restraint bands 11, for example, the outer bag body side surface 5 may be disposed in order so as to go around the circumference direction using a plurality of bands, or the restraint bands 11 are changed in height. You may distribute it up and down. For example, by arranging the restraining band 11 around the side of the head of the seated person and the restraining band 11 around the side of the foot, the method of tightening the band on the head side and the end of the foot Since the method of tightening the restraining band 11 can be changed, it becomes easy to adjust the height position of each of the head and the leg to a desired state. This is because the flow area of the beads of the particulate foamed resin body 8 filled in the inner bag is suppressed.

  In addition, by arranging a plurality of restraint bands 11 in parallel while changing the height on the side surface around the head side of the outer bag body 2, it is possible to adjust the tightening for each restraint band 11 so that granular foaming can be achieved. The movement of the resin body 8 is efficiently restrained to facilitate formation of a desired sitting posture. For example, it is also possible to change the tightness with the restraining bands 11 disposed on the head side and the leg side respectively. Further, in the case where the plurality of restraint bands 11 are arranged in parallel by changing the height in the vertical direction to the head side, the tightening condition of the upper restraint band 11 is relaxed while loosening the clamps of the lower restraint bands 11. It is possible to secure the rising of the cushion on the head side to a height of 45 cm or more to make it difficult for the head cushion to sink down by tightening the upper side.

By the way, as in the seventh means, when the pull-out belt 18 is provided separately from the restraint band 11 in the cushion 1 of the present invention, the beads of the granular foam resin body 8 are driven in the pulled-out direction only by pulling out. Can be moved. Then, since the beads flow around and support the seated person, the posture can be easily maintained. For example, the draw-out belt 18 has a width of 4 cm and a length of about 1 m50 cm to 2 m50 cm, and the left and right sewn parts 19 face the lower end of the left and right side inner surface side of the rectangular outer bag body 2 at both ends of the belt. It shall sewn in position, keep the belt central portion 21 from the outer bag 2 of the opening 20 is exposed to the outside in advance so as to withdraw any. The openings 20 are provided at one or two places on the side remote from the side to which the belt is sewn , and the belt central portion 21 is exposed to the outside from the openings 20. By providing two openings 20 so that the belt center portion 21 of the draw-out belt 18 can be taken out of those openings, the draw-out belt can be inserted into the outer bag 2 between the openings 20 and 20 of the outer bag side 5. Since the movement is blocked, it does not get into the gap between the inner surface of the outer bag body 2 and the inner bag portion, and the belt central portion 21 is always exposed, so that it becomes easy to pull out.

When the draw-out belt 18 is pulled out, the side surface around the sewn portion 19 is pulled so as to be drawn to the center of the cushion, and the beads 8 generally flow largely as the belt moves. . In addition, the belt central portion 21 may be bent in advance by curving the belt in advance so as to be easily grasped, and may be used as a handle. Incidentally, the pull-out belt is a pull out relationship, sewn portion may be provided at the lower end side of the leg and waist of the left and right sides, openings may be provided at a position of the center of the slightly higher head side surface, It is desirable for the bead to be fitted while the bead is pulled up with an operation of pulling up slightly from the lower side.

  The pull-out belt 18 and the restraining band 11 can be used by mounting them in one cushion. The draw-out belt 11 is suitable for causing the granular foamed resin body 8 to largely flow to fit the posture of the seated person, and can be adjusted only by pulling it out, and it is convenient because it does not require an operation of fixing the length. In addition, if the constraining bands 11 are arranged short on the side and around the side, the length can be adjusted locally and fixed, so that the length of the constraining bands can be maintained to maintain the posture formed by the draw-out belt 18 By adjusting the height, the posture can be further moved, and the obtained posture can be held for a long time, so it is suitable for holding a suitable posture for a certain period of time.

  By the way, you may make it provide a footrest in the exterior side of the cushion of this invention. For example, as in the ninth means, the cushion is inclined in advance so that a part of the seating surface 3 is an inclined surface, the head of the seated person is on the right side, and the seated person's leg is on the left side. In this case, the right side of the cushion that supports the head is high, and the outer bag body 2 has a shape that gently inclines downward from the middle of the cushion toward the left side, and the inner bag is filled with the granular foam resin body 8 Supports the seat occupant in an inclined state, and the leg base 15 for mounting the leg from the lower end of the slope can be provided to project from the outer bag body 2 to support the seat occupant's upper limb outside the cushion It can be

  The footrest for supporting the upper limbs is such that the support portion 17 supports the placement portion 16 from the lower side, and is inclined in the direction opposite to the inclination on the cushion side. The placement unit 16 is slightly elevated. That is, the inclination of the cushion and the inclination of the mounting portion 16 of the footrest 15 for supporting the upper limb draw a loose V-shape. The seat occupant can then sit to bend the body in a v-shaped manner along the loose V-shape, i.e., with the waist positioned near the lower end of the slope of the cushion. Then, the load on the upper body of the seat occupant is distributed and supported by the granular foamed resin body 8 in the cushion, and the inner thigh side of the upper limb is also supported by the footrest so that the waist can be seated in a bent shape It is possible to easily form a relaxed comfortable posture because the sciatic of the person is pushed forward and inclined and the two muscles of the lower iliopsoum and lower gluteus muscle groups in the lower abdomen are balanced. It becomes.

Further, as in the tenth means, the leg base 15 projecting so as to project outward may be constructed as an adjustable one so that it can be raised and lowered in a state where it rises obliquely from the horizontal state. The leg base has a placing portion 16 for placing and placing the upper limbs, and the placing portion 16 is joined to the outer edge of the lower bag 2 on the lower end side by sewing or the like, and the joined outer edge As an axis, the mounting portion 16 can freely move up and down from a horizontal posture in a state of being lowered to a posture which is raised obliquely. Moreover, the mounting part 16 raised diagonally is supported by the support part 17 supported from the lower side so that angle adjustment is possible.

In order to make it foldable, the placement unit 16 places a cloth such as canvas on a 30 cm long board with a width of about 50 cm, and supports the right and left with a cushion frame, and the placement unit 16 Since the lower end of the case is sewn to the outer bag body 2, the lower end of the lower case stands obliquely around the sewn portion 14 as an axis. Since the support portion 17 supports the support portion 17 from the lower side from the lower side of the mounting portion 16 in a manner similar to a rod, the inclination angle at which the leg of the mounting portion 16 is placed can be freely adjusted depending on the inclination of the support portion 17 It will be. The support portion 17 may be a member formed in a rectangular frame or the like using, for example, a lumber having a thickness of about 1 cm so as not to be an obstacle when folded horizontally.

  If it is a healthy person, since it can sit without using the foldable mounting portion 16 or the like, it is possible to take a comfortable sitting posture by sitting on a rectangular cushion without using such a foot stand 15. However, some disabled people working on rehabilitation include those who can not take enough action for sitting because the muscles are stiff and their moving range is limited etc. . Even if those persons with disabilities try to sit on the cushion of the present invention in order to relieve tension and relax, the cushions having a height, even with the help of an attendant, do not require labor and do not require a rectangular parallelepiped. It is not easy to sit in the center, so it will be difficult to use it for rehabilitation casually.

  Therefore, while sitting down stably on the lower side of the upper flat surface where the height is lowered, and putting the upper body on the cushion, the upper limbs are placed on the horizontal footrest mounting portion 16 Then, by raising the placement portion 16 so as to incline obliquely, bending the upper limbs, adjusting the left and right band lengths, and adjusting the height and position of the cushion on the head side, appropriate relaxation is possible. We will form a shape that matches the posture.

  The cushion 1 of the present invention is also suitable for long-term rest, but is particularly suitable for use in rehabilitation for disabled people. Normally, the muscles become tense and become rigid and the movable range narrows, adjust the length of each restraint band 11 to balance the load so that the cushion of the present invention releases the tension. If you adjust the sitting posture to suit you, muscle tension will be relaxed. Then, as a result of the muscles being relieved from tension, the body becomes comfortable, and it takes only 10 minutes to sit, and the joints of the limbs that have been strained can be moved easily.

  For example, when sitting on the cushion 1 of the present invention for the rehabilitation of an elderly person who has suffered physical disability due to a cerebral infarction etc., first, after sitting on the cushion 1, he should follow the person's curved posture. The height of supporting the head and legs is formed by adjusting the height of the restraint band 11 and the footrest 15. After obtaining a comfortable posture, you will sit for about 10 minutes and then exercise for the four limbs to extend the range of motion as rehabilitation to move the physical joints. When the treatment was repeated after several days and the treatment was performed, recovery of the movable range could be smoothly progressed without excessive burden on the person or the practitioner. It is very laborious to promote movement by the operator's arm strength etc. without relieving tension, so the efficiency of rehabilitation has greatly changed.

  Also, as in the above-mentioned 11 means, filling the head side and the leg side by making the sizes of the inner pouch of the large inner pouch 9 and the small inner pouch 10 different from the size of the inner pouch of the inner pouch portion 7 different. Since the amount of material can be changed, it is easy to make a difference in height that can be formed by shrinking the restraint band 11. For example, the large inner bag 9 has a width 750 mm × length 750 × height 450 mm, the small inner bag 10 has a width 750 mm × length 400 mm × height 270 mm, and the inner bag portion 7 has a capacity larger than the capacity of the outer bag body 2 Further, as the granular foamed resin body, 3 kg of powdery beads are filled in the large inner bag and 2 kg in the small inner bag. Now, by forming the inner bag portion 7 having a larger capacity than the outer bag body 2, the outer bag body 2 is pressed from the inside centering on the expansion and contraction surface and is in a state of being rounded on a curved surface . By doing this, the rectangular outer bag body 2 is sufficiently inflated by the contents, so that even if the load of the seated person is supported, the beads of the granular foam resin body do not flow too much and it is easy to maintain the sitting posture It will be a thing and will not be dented like a cushion being crushed. On the other hand, while the large inner bag and the small inner bag are sufficiently filled with beads, respectively, they can expand and contract, and although the outer bag body is sufficiently inflated, the large inner bag and the small inner bag In any case, each single substance has a size large enough for the beads to move inside, and if the shape changes, there is room for the beads to flow inside. Therefore, if the length of the restraint band 11 is adjusted and tightened, it becomes easy to change its posture, and the bead of the granular foam resin body 8 flows even when the seated person applies a load. Since there is no need to overdo it, the desired cushion height can be secured sufficiently.

  As an example of the embodiment of the present invention in FIG. 1, a substantially rectangular outer bag 2 having a total length of 120 cm, a total width of 60 cm and a height of 45 cm, and an inner bag portion 7 therein, 1 mm of the granular foamed resin body Fig. 6 shows a cushion that encloses inner bags of two different sizes, of different lengths, consisting of elastic cardboard knits filled with beads of diameter. The inner bag portion has the same overall width and height as the outer bag body, but includes the inner bag 9 having a total length of 75 cm and the small inner bag 10 having a total length of 40 cm in the outer bag body 2. The upper flat surface of the outer bag body 2 is a seating surface 3 made of a cardboard knit which is a 120 cm × 60 cm stretchable material, the side surface is made of 240 × 45 cm non-stretchable canvas, and they are sewn, Fasteners are provided in a part thereof to provide an openable / closable opening so that the inner bag can be stored inside the outer bag body. Both large and small inner bags are filled with beads to the extent that the bags extend and expand slightly, and the capacity is rather large, so the inner bag part is stored inside the outer bag body so as to spread out. As a result, bulkiness is likely to be secured. The large inner bag 9 side supports the upper body portion from the head of the seated person to the waist, and the small inner bag 10 side supports the buttocks and upper limbs of the seated person. Also, from the side of the head side to the bottom, the outer bag is loosely rounded at about R 20 cm, and the rounded corners are also made of canvas similar to the side, so a cardboard knit of elastic material at the bottom As for the size, the bottom surface is 90 cm long × 60 cm wide, while the upper flat surface has a length of 120 cm over the entire top surface. That is, on the bottom side near the head of the seated person, expansion and contraction is difficult by securing a large surface of the rounded canvas material. By using a material that does not easily expand and contract around the head side, it is difficult for the beads to flow around, so when adjusting the band length of the restraining band, it becomes easier to secure the thickness (height) on the head side, It is suitable.

On the side surface 5 of the rectangular outer bag body 2 of the cushion 1, a restraining band 11 from the center on the right side to the center on the left side through the head side and the center from the left side to the side on the leg side to the center Restraint bands 11 are arranged in a total of 4 sets of 2 sets at different heights. Each of these restraint bands 11 is formed as a restraint band 11 by connecting the part A on the side of the sewn part and the part B on the side of the mooring part via the buckle 25. In part A, the band is inserted into the inside from the left and right side openings (band insertion hole 22) of the outer bag, and bifurcated after being inserted in the vicinity of the left and right openings (band insertion hole 22) (Branch part 23), the band which has branched from the inner bag part 7 along the side inner surface of the outer bag body 2 in a state where the outer bag body inner surface on the head side or leg side is separated in parallel The center of the spaced apart portion is sewn on approximately 50 to 60 cm in the longitudinal direction (horizontal direction) with the inner surface side of the outer bag to form a sewn portion.

Part B of the restraining band 11 is formed in a string-like pulling the folded portion 24 of the buckle 25 side as a folded belt, and sewn to the side surface 5 of the outer bag 2 and the other end of the belt part B as mooring unit 12, By adjusting the length on the part B side by inserting and folding back to the ring part in the buckle, the entire band length of the restraint band 11, ie, the length between the sewing part 14 and the mooring part 12 is adjusted It is possible. (A) and (b) of FIG. 2 show how the shape of the cushion 1 changes before and after the length of the restraint band 11 is adjusted. In addition, although each restraint band 11 of FIG. 2 is strip | belt shape, although the one part is distribute | arranged along the inside of the outer bag body 2, it simplifies and shows arrangement by a straight line. It is the distance between the mooring portion 12 and the sewing portion 14 that the length is specifically clogged in the side surface 5, and the surface on the sewing portion 14 side only moves as a whole as a surface . The movement of the side surface is indicated by an arrow as a thick arrow in FIG. Since the side 5 around the sewn part is not contracted, when the length of the band 11 is reduced, the sewn part 14 disposed on the side on the upper side of the head or the side on the lower side of the leg It moves so as to be drawn toward the center of the cushion 1 with the surrounding outer bag side 5.

Posture adjustment of a seated person at the time of sitting on this cushion is carried out as follows. First, the large bag side is the upper body, and the small bag side is the direction to put the legs, and the outer bag body of the bottom of the large bag side near the head is rounded and the non-elastic canvas is large. Because it is distributed and non-stretchable, the sitting posture on the upper body side is likely to change significantly when the band length is adjusted. First, the restraint band is loosened, and after sitting down, the folded side 24 of the band on both sides is grasped by hand and pulled to cushion the side surface 5 on the head side centering on the sewn portion 14 of the restraint band 11 Since it moves as a surface so as to be drawn to 1, the bead of the particulate foamed resin body 8 filled in the inner bag portion 7 following this movement flows and moves so as to escape to an expandable portion. As a result, the head side is held by the upper body located high. Since there are two sets of restraint bands 11 with different heights at the top and bottom, the length is changed at the top and bottom to adjust the degree of tightening appropriately so that a comfortable posture can be obtained. For example, in order to shorten the length of the lower band, by pulling the folded back portion 24 largely, the seat surface is slightly pushed upward, and the shape of the cushion changes as the thickness increases. Similarly, the restraining band around the lower leg can be easily pulled higher after sitting to increase the height of the lower knee than the waist. In addition, if you continue to adjust the band length at one end, if you sit again and again, without having to adjust each time, because it holds the previous position, in the posture as shown in Figure 2 (c), from the beginning It becomes easy to obtain a comfortable comfortable posture.

  Now, when sitting on the above cushion 1 and adjusting the band length of the restraining band 11 by pulling the folded back portion 14 respectively, the side shape of the cushion shrinks and changes more complicatedly as compared with a simple rectangular bead cushion. The cushion has a three-dimensional shape as shown in FIG. For example, obtain a shape such that the bead on the head side is thick, the contact area of the waist is low, and the upper limb bends in the opposite direction from the part where the upper limb is placed to the back of the knee. It becomes possible to hold this. Then, by making the head high, the seated person can easily view the front of the television etc. without applying a load on the neck and can lean against the body diagonally, so the body pressure is dispersed and the body is wider. It is held by the surface. In addition, since the hips and the upper limbs can be seated on the opposite inclined surface so as to round the waist, the balance of the iliopsomus group and the gluteus muscle group is balanced, and it is easy without stress. Being able to form a posture makes it easy to maintain a relaxed state of the muscles of the body. Furthermore, since the elastic upper plane conforms to the shape of the body and the beads support the periphery of the body from the periphery by the general grounding, sufficient body pressure distribution can be achieved, and the elastic upper plane Unlike the cushions that are simply restrained by restraint because they have the ability to keep supporting even if you shake your body a little while sitting, you can sit comfortably without being tired even if you keep sitting for a long time did it.

  Next, as another embodiment, as shown in FIG. 4, the upper surface of the outer bag body 2 of the cushion 1 is inclined from the middle and descended, and the cushion provided with the footrest 15 at the lowered end is an embodiment. Shown as 2. The shape and size of the outer bag body 1 is 70 cm in width on the head side and 50 cm in width on the leg base side when the left side is the head side and the right side is the foot side of the outer bag body having a total length of 90 cm. In the plan view from above, the two corners on the head side of the outer bag body 1 are rounded at a radius of 30 cm. In addition, the outer bag body 1 has a height of 40 cm on the upper side of the head side and a height of 4 cm on the leg base side when viewed from the side, and 30 cm from the head side end It descends to the pedestal side while drawing a gentle arc of the lower chord with a radius of 60 cm. Further, the outer bag body is a full-length stretchable cardboard knit on the bottom surface and a non-stretchable canvas fabric on the side surface. In addition, although elastic cardboard knits are used for the upper flat surface on the inclined surface which is the seating surface to be in contact with the back surface of the seat occupant, the non-stretchable width of about 20 to 25 cm wide on the upper flat surface on the head side I use canvas. In this case, when tightening the head of the seat occupant, the portion adjacent to the stretchable seating surface is made non-stretchable to increase the restraint force and follow the change in the cushion shape.

And the restriction bands 11 made of polypropylene of short length are arranged on the left and right sides respectively. Each restraint band is a band integrated with a part B having a part A provided with a sewn part on the side 5 on the head side and a mooring part disposed on the left side or the right side via a buckle. Part B has a buckle that allows the length of the mooring part and the buckle to be variably adjusted by folding the band. Sewn portion of the part A are those inserted through the belt inside the opening of the outer bag is the inner surface side and the sewing of the outer bag, the inner surface of the sewn portion 14, further outer bag A triangular patch is placed on the side for reinforcement, and this patch can be moved so as to draw the side of the surrounding as a face. Against this may be allowed sewn to further reinforce the polypropylene band and the same material of the belt to the cloth. In addition, also in the mooring portion, the belt inserted from the opening of the outer bag body is fixed to the side surface of the outer bag body. Since the left and right restraint bands 11 can be adjusted individually, the degree of tightening can be changed individually for persons with disabilities etc. who tend to lean left or right when seated, so it is possible to follow the sitting posture Being supportive, it is easy to form an appropriate support for releasing tension.

Furthermore, a central portion 21 serving as a handle of the drawer belt 18 is exposed at the center on the side of the head side of the outer bag body, and the drawer belt 11 is made of propylene having a width of 4 cm. It is fixed by sewing to the lower end near the foot stand 15 of the right and left of each side of the outer bag through the inside of the outer bag from two openings 20 at the center of the side of the side. When the center part of the drawer belt is pulled out after sitting, the upper body of the seat occupant is lifted up while being pulled up while flowing in the direction in which the bead of the granular foam resin body is pulled out when pulling out. In the body, the beads flow to the lines of the body and naturally follow it. And since the state as it is is hold | maintained without returning by the load of a seating person even if it does not fix a drawer belt, arrangement | positioning of the bead along a seating person's comfortable attitude | position can be comfortably formed. As shown in FIG. 5, the footrest 15 is foldable, and after being seated, the footrest 15 is used in an inclined manner so that the support 17 supports the mounting portion 16 from below. The tilt angle is adjusted in accordance with the tilt of the support 17. A wooden laminated board or the like is used as the support 17 and covered with canvas or the like in the same manner as the outer bag.

  An elderly disabled person whose working range of the joints in the limbs was narrowed was used by sitting on the above cushion as follows. It shows a state of sitting on (a) to (c) of FIG. First, the waist of the seated person is located below the inclined surface of the cushion, and as shown in FIG. 8 (a), the buttocks and the heel are placed on the placement portion 16 of the footrest 15 which remains horizontal. The seater is seated on his back, with the head positioned on the side of the non-tilted, high-bulk area opposite to the legs. Under the present circumstances, as shown in FIG. 4, if a circular position mark is drawn on the foot stand 15 and a buttocks will be contact | abutted to this, it will become easy to form an appropriate seating attitude. Since the leg base 15 has a low position at the time of sitting in the horizontal position to lower the waist, it is possible to easily sit safely even if there is an obstacle in the body.

  Next, as shown in FIG. 5 and FIG. 8 (b), the support portion 16 of the footrest 15 is inclined to support the support portion 17 from below to make the back of the knee of the seat occupant high. Lift the upper limbs to form a sitting posture with the upper body and upper limbs bent gently. By raising the placement portion 16 diagonally from the horizontal state, the buttocks and the thighs are supported by the placement portion 16 and the upper body is placed on the seating surface 3 of the cushion. At that time, in order to be able to put the upper body of the seated person on the outer bag body 2 comfortably, the thickness is adjusted so that the cushion on the head side becomes high according to the posture of the upper body. Therefore, as shown in FIG. 8C, the belt length of the restraint band 11 is adjusted by pulling in the direction of the arrow, etc., and the outer bag body 2 left and right side face 5 are tightened. Move to the whole. Then, the drawer belt 18 exposed to the head side from the lower side is pulled out in the direction of the arrow in FIG. 8C, and the upper side surface is entirely contracted to the center together with the outer bag body. As the beads of the granular foam 8 are drawn back slightly upward to flow into the gaps around the body, the beads are naturally induced to fill the gaps generated by the posture movement.

  In this way, after a seated person with four limbs is seated, the length of the restraint band is adjusted, the pullout belt is pulled to maintain the posture sufficiently, and then it is left for 10 minutes as it is comfortably seated. After that, the difference in movement range of the shoulder joint immediately after sitting and after 10 minutes was confirmed. Then, the range of motion of the shoulder joint was expanded by about 10 degrees compared with that immediately after sitting, and the shoulder turned slightly, and a change in the range of motion was observed. The muscle remained rigid due to the shape not conforming to the body by simply placing it on a general level cushion or bed, and it was not recognized that the range of motion changed in only about 10 minutes. On the other hand, in the case of the cushion of the present invention, a change was observed in 10 minutes. This is because it is possible to support while dispersing the body pressure so as to follow the posture of the current seated person, so that by supporting the whole body without hesitation, a comfortable state where strain is relieved is fostered I think that the. It was confirmed that the range of motion of the joint was expanded despite the use of only a few minutes to about 10 minutes because the muscle tension of the seated person was relieved.

  As described above, when the present invention is applied to a disabled person, it is possible to support with a comfortable posture in accordance with the current posture, so that rehabilitation capable of expanding the range of motion of the joint can be effectively realized. Then, since it is not necessary to apply an exercise load which forcibly extends the movable range, subsequent rehabilitation training can be advanced efficiently. And there is little physical burden on the seated person and the person who assists, and it is possible to work on rehabilitation repeatedly. In addition, when rehabilitation training is repeated, it is possible to make adjustments such as adjusting gradually from the previous fixed position, so that it is possible to flexibly follow the difference in posture that changes according to the progress of rehabilitation. Therefore, it is a cushion suitable for rehabilitation with high adjustment width and good followability, such as being effective for application to patients whose seating posture changes as the condition gradually improves. confirmed.

Further, as another embodiment, FIG. 9 shows a cushion 1 with a footrest 15 and using only a restraining band 11 whose length can be adjusted without using the pullout belt 18. There are two sets of restraint bands 11 at the top and bottom, and in each set, the center of the band is bifurcated and sewed on the inner surface side of the outer bag side 5 at the top of the head. And the length between the sewing part 14 and the mooring parts 12 on the left and right sides can be changed by adjusting the amount of withdrawal of the folded back part 24 so that the shape of the cushion on the head side can be largely changed. ing. The usage method of adjusting the length of the restraint belt 11 after seating to form the seating posture is the same as that of the second embodiment, but when using the drawer belt 18, the upper body is lifted by pulling out and the beads are at the same time When the restraint belt 11 is used, the beads can be made to flow by moving the side surface 5 on the head side toward the center of the cushion 6 and the upper body of the seater can be largely pushed up. .
