Description

  The present invention relates to a cushion that corrects the posture when seated.

  In the human body, there is a difference in the amount of muscle tension in the front, back, left and right due to lifestyle habits, such as the difference between the right and left of the dominant arm and dominant hand, and office work in the same posture for a long time. As a result, the skeleton is pulled toward the person with more muscle tension, and the skeleton may be distorted back and forth and left and right. It is known that when such skeletal distortion occurs, the posture deteriorates, and as a result, the load acting on each part of the body due to gravity is biased in one direction, causing stiff shoulders, headache, decreased visual acuity, etc. .

  When the balance is lost due to such skeletal distortion, the load on the upper body acts on the hips even when sitting on a chair, etc. It becomes stable. Further, if such a state continues, there is a risk of causing back pain and the like.

Patent Document 1 describes a cushion that corrects the posture when sitting on the basis of a difference in thickness between another part and the thick part, with half of the seating surface being a thick part. As shown in FIG. 8, in this cushion 1, the right side portion of the seat surface 2 in FIG. 8 is a thick portion 3 that is thicker than the left side portion. According to such a cushion 1, as shown in FIG. 9, the portion in contact with the thick portion 3 in the seated state is held in a state of being lifted more than the other portions. Thereby, the posture when sitting can be corrected, and the distortion of the skeleton can be corrected.
JP 2000-237221 A

  By the way, the lifestyles described above are different for each person, so the direction of the skeletal distortion caused by the difference in the amount of muscle tension, the degree of the distortion, and the way the balance is lost due to this distortion are different for each person. It will be. Therefore, in order to correct the posture when sitting with the cushion 1 as described above, the direction and the degree of correcting the posture are adjusted according to the distortion of the skeleton and the balance of each person. Is desirable.

  However, in the case of manufacturing cushions in which the posture is corrected in accordance with the skeletal distortion and balance of each person, and the degree of the cushion is adjusted, an increase in cost is inevitable. .

  The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a cushion that can easily correct postures corresponding to different skeletal distortions and balances.

In the following, means for achieving the above object and its effects are described.
The invention according to claim 1 is a seat cushion for correcting a posture when seated by making a part of the seat surface thicker than other portions, and the seat surface is centered on the center thereof. Are divided into four parts that respectively contact the right thigh, left thigh, stark buttock, and left buttock, and one of the four parts serves as a first thick part, and the 4 The gist of the present invention is that an adjustment member having this part as the second thick part is detachably provided at a part adjacent to the first thick part among the two parts.

  According to the above configuration, the seat surface is divided into four parts so as to correspond to the right thigh, the left thigh, the starboard part, and the starboard part with the center at the center, and one of the parts is the first part. It is considered to be a thick part. For this reason, by changing the laying direction of the cushion, that is, by rotating the cushion around the center of the seating surface, the portion where the first thick part abuts is the right thigh, left thigh, starboard, It can be selected from the left side and the direction of correcting the posture when seated can be adjusted. Moreover, since the adjustment member which makes this site | part 2nd thick part detachable is provided in the site | part adjacent to the said 1st thick part, by attaching the said adjustment member, 1st thick part And the second thick part can cooperate with each other so that two adjacent parts of the four parts can be made thick parts. Even when the adjustment member is attached as described above, the left and right thighs, the right thigh and the right hip, the left and right hips, and the left thigh can be rotated by rotating the cushion on the center of the seating surface. And the site | part with which a thick part contact | abuts can be selected from among port part. In other words, according to the first aspect of the present invention, the direction in which the posture is corrected is selected in the form of the four patterns in the form of only the first thick part, the four patterns in the form of the adjustment member attached, and the total of eight patterns. Will be able to. This makes it possible to easily correct postures corresponding to different skeletal distortions and balances.

  In addition, when the seating surface is divided into four parts so as to correspond to the right thigh, left thigh, starboard, and left hips, the seating surface is divided into four equal parts approximately 90 ° centering on the center. It is desirable to partition it. The thickness of the thick portion is particularly preferably about the thickness of the palm in consideration of the comfort of sitting when sitting.

  According to a second aspect of the present invention, in the cushion according to the first aspect, the seat surface is interposed between a pair of cushion members made of an elastic member and the pair of cushion members, and the first meat. It is formed by laminating a fixing member that forms a thick portion, and the gist is that the adjustment member is detachably interposed at a portion adjacent to the fixing member between the pair of cushion members. .

  Specifically, according to the invention described in claim 2, the seat is formed by laminating a pair of cushion members and a fixing member interposed between the pair of cushion members to form the first thick portion. A configuration for forming a surface can be employed. According to such a configuration, the first thickened portion that is thicker than the other part due to the thickness of the fixing member and the step between the other part do not appear directly on the seating surface, so the sitting comfort when sitting is improved. can do. Moreover, a 2nd thick part can be formed now by interposing an adjustment member between a pair of cushion members.

The gist of the invention described in claim 3 is that, in the cushion cushion according to claim 2, the pair of cushion members have different thicknesses.
The gist of the invention described in claim 4 is that, in the cushion cushion according to claim 2 or claim 3, the pair of cushion members are formed of members having different elastic coefficients.

  According to the third aspect of the present invention, since the thickness of the pair of cushion members constituting the seat surface is different, when using this cushion with the thinner cushion member as the upper surface, a pair of cushion members is used. A step due to the thickness of the fixing member and the adjusting member interposed between the two members appears on the seating surface through the cushion member having the smaller thickness. Therefore, the difference in thickness between the thick part and other parts is likely to appear on the seating surface when seated. On the other hand, when this cushion is used with the thicker cushion member as the upper surface, a step due to the thickness of the fixing member and the adjusting member appears on the seat surface via the thicker cushion member. For this reason, when the user sits down, the thickness difference between the thick portion and the other portion appears more gently on the seat surface than when the cushion member having the smaller thickness is used as the upper surface. That is, according to the configuration of the third aspect, it is possible to select the degree of correction and the seating comfort, so-called feeling of use, with respect to the correction directions of the eight patterns by properly using the front and back of the cushion. The correction method can be adjusted in a total of 16 patterns.

  Moreover, even when the pair of cushion members are formed of members having different elastic coefficients as in the invention according to the fourth aspect, the feeling of use can be selected by properly using the front and back of the cushion. It becomes like this. Specifically, when using this cushion with a smaller elastic coefficient, that is, a softer cushion member as the upper surface, there is a step due to the thickness of the fixing member and the adjustment member interposed between the pair of cushion members. It appears on the seat surface through the softer cushion member. Therefore, the difference in thickness between the thick part and other parts is likely to appear on the seating surface when seated. On the other hand, when this cushion is used with the larger elastic coefficient, that is, the harder cushion member as the upper surface, a step due to the thickness of the fixing member and the adjusting member appears on the seating surface through the harder cushion member. Therefore, when seated, the difference in thickness between the thick portion and other parts appears more gently on the seat surface than when the harder cushion member is laid on the upper surface.

  In addition, the structure of Claim 3 and the structure of Claim 4 are combined, and the feeling of use of the front and back surfaces of the cushions may be made different by making the thickness of the pair of cushion members different from the material thereof. it can. In this case, one surface is formed thick with a hard member, while the other surface is formed thin with a soft member, thereby suppressing an increase in the overall thickness of the cushion, and a difference in feeling of use due to a difference in the front and back of the cushion Can be made clear.

  According to a fifth aspect of the present invention, in the cushion according to the first aspect, the seat surface is formed by a cushion member made of an elastic member, and the first thick portion is a surface of the cushion member or It is formed so as to protrude to one of the back surfaces, and the adjustment member is detachably provided on the surface of the seat surface or the back surface of the first thick portion protruding. The gist.

  Further, the first thick portion is formed by forming the first thick portion so as to protrude from one of the front surface and the back surface of the seat surface as in the invention described in claim 5. The structure which forms a 2nd thick part by attaching an adjustment member to the surface which protrudes can also be employ | adopted. In the case of adopting such a configuration, when this cushion is used with the surface formed so that the first thick portion protrudes as the upper surface, the first thick portion and the second thick portion are used. A step due to the thickness of the thick part appears directly on the seating surface. On the other hand, when this cushion is used with the other surface as an upper surface, a step due to the thickness of the first thick portion and the second thick portion appears on the seat surface via the cushion member. That is, even when the configuration according to claim 5 is adopted, it is possible to select a feeling of use for each of the eight patterns of correction directions by properly using the front and back of the cushion. The correction method can be adjusted in the pattern mode.

  The invention according to claim 6 is the cushion according to any one of claims 1 to 5, wherein the cushion is further provided with a bag-like cover and is used in the state of being put in the cover. The gist of the present invention is that a mark is provided on at least one of a position corresponding to the first thick part and a position corresponding to the second thick part.

  According to the invention described in claim 6, the cushion includes a cover provided with a mark in at least one of a position corresponding to the first thick part and a position corresponding to the second thick part, It is desirable to use it in this cover. By using the cover in such a state, it is possible to visually recognize the position of each thick portion and determine the orientation of the cushion.

  In addition, although the structure which provides the said mark in any one of the position corresponding to a 1st thick part and the position corresponding to a 2nd thick part can also be employ | adopted, the said 1st thick part is adopted. It is more desirable to provide marks at both the corresponding position and the position corresponding to the second thick portion. And when providing a mark in both positions, a mutually different mark can be provided and the position corresponding to a 1st thick part and the position corresponding to a 2nd thick part can be discriminate | determined visually. It is further desirable to do so.

  In addition, the mark here includes a color, a pattern, a display by characters, a combination of these, and a decorative object such as a tag or a ribbon, and visually distinguishes each thick part from other parts. Anything is possible.

  The invention according to claim 7 is the cushion according to any one of claims 3 to 5, wherein the cushion is further provided with a bag-like cover, and is used in a state of being put in the cover. The gist of the cover is that the design differs between the front surface and the back surface of the seat surface.

  The invention according to claim 8 is the cushion according to claim 7, wherein the cover has at least one of a position corresponding to the first thick part and a position corresponding to the second thick part. The gist is that a mark is provided on the.

  When adopting a configuration in which the feeling of use can be selected by properly using the front and back of the cushion as in the inventions of claims 3 to 5, the invention of claim 7 is used. It is desirable to provide a cover with different designs on the front and back surfaces of the cushion and use the cover in this cover.

  Hereinafter, an embodiment embodying a cushion according to the present invention will be described with reference to FIGS. First, the structure of this cushion is described with reference to FIG. FIG. 1 is an exploded perspective view showing the configuration of the cushion according to the present embodiment.

  As shown in the center of FIG. 1, the cushion body 10 is formed by laminating a first cushion member 11, a second cushion member 12, and a fixing member 13. The 1st cushion member 11 and the 2nd cushion member 12 consist of elastic members, such as urethane foam, and comprise the substantially square plate shape where the length L2 and the width W2 are respectively equal as FIG. 1 shows. ing. In addition, the thickness T2 of the first cushion member 11 is set to a value larger than the thickness T1 of the second cushion member 12.

  Between the first cushion member 11 and the second cushion member 12, a fixing member 13 having a substantially square plate shape having a length L1 and a width W1 is fixed. The fixing member 13 is made of an elastic member such as urethane foam that is harder than the first cushion member 11 and the second cushion member 12, that is, has a large elastic coefficient, and the length L1 and the width W1 thereof are the cushion members 11, The size is set to approximately half the length L2 and the width W2. Further, the thickness T3 of the fixing member 13 is set to a value larger than the thickness T2 of the first cushion member 11 and the thickness T1 of the second cushion member 12. Note that the thickness T3 of the fixing member 13 is preferably set to a thickness of the palm in consideration of sitting comfort.

  As shown in FIG. 1, the fixing member 13 is a lower right portion in FIG. 1 among four portions that divide the first cushion member 11 from the center thereof in the circumferential direction approximately every 90 °, that is, approximately in four equal parts. It is adhered to the part located in

  The second cushion member 12 is bonded onto the first cushion member 11 so as to sandwich the fixing member 13 fixed to the first cushion member 11, and thus the first cushion member 11 and The main body 10 is formed in a state where the fixing member 13 is stacked between the second cushion member 12 and the second cushion member 12.

  Here, when the first cushion member 11 and the fixing member 13 are bonded to the second cushion member 12, the upper surface of the fixing member 13 and the above-described four portions in the first cushion member 11 are partitioned. Of the formed parts, the part excluding one of the parts adjacent to the part to which the fixing member 13 is adhered, that is, the part indicated by hatching in FIG. 1 is adhered. As a result, the first cushion member 11 and the second cushion member 12 are not bonded to each other at a portion adjacent to the fixing member 13 between the first cushion member 11 and the second cushion member 12. A gap is formed between the cushion members 11 and 12.

  In this gap, an elastic member similar to the fixing member 13 is formed, and as shown in FIG. 1, a substantially square plate having the same shape as the fixing member 13, that is, a length L1, a width W1, and a thickness T3. The adjusting member 20 having a shape is inserted.

  The main body 10 formed in this way is put into a bag-like cover 30 formed by sewing cloths as shown in FIG. As shown in FIG. 1, an opening 35 for inserting and removing the main body 10 is formed on one side of the cover 30. A slide fastener that can freely open and close the opening 35 by sliding a slider in the opening 35. 36 is provided.

  Further, the cover 30 is formed of a white cloth having a front surface 31 which is an upper surface in FIG. 1, while a back surface 32 which is a lower surface in FIG. 1 is a black cloth. Is formed. The front surface 31 is printed with a black circle 33 at a position corresponding to the fixing member 13 in a state in which the main body 10 is included, and also corresponds to a portion where the adjusting member 20 is detached. A black square mark 34 is printed at the position. On the back surface 32, a white circle 37 is printed at a position corresponding to the fixing member 13, and a white square mark 38 is printed at a position corresponding to a portion where the adjustment member 20 is attached and detached. ing.

  FIG. 2 is a perspective view showing a state in which the main body 10 is put in the cover 30. In this cushion 100 formed as described above, the portion where the fixing member 13 is sandwiched as shown in FIG. 2 is thicker than the other portions by the thickness T3. The thick portion 111 is formed.

  Further, as shown in FIG. 2, a gap 15 in which the adjustment member 20 can be inserted is provided between the first cushion member 11 and the second cushion member 12 in a portion adjacent to the first thick portion 111. Is formed. By inserting the adjusting member 20 into the gap 15 as indicated by an arrow in FIG. 2, the portion adjacent to the first thick portion 111 is made thicker than the other portions in the same manner as the first thick portion 111. The thick second thick portion 112 can be obtained. That is, in the seat cushion 100 of the present embodiment, by removing the adjustment member 20, the area of the thick portion 110 that is thicker than other portions can be changed, and half of the seating surface can be changed to other portions. The state where the thick part 110 which is thicker than the part occupies and the state where the thick part 110 occupies a quarter of the seating surface (hereinafter referred to as ¼) can be appropriately changed.

Hereinafter, the usage mode of the cushion 100 will be described in detail with reference to FIGS.
FIGS. 3A to 3D are schematic views showing a mode in which the cushion 100 is used without attaching the adjustment member 20, that is, a state in which the thick portion 110 occupies ¼ of the seating surface. . In addition, in this figure, the state when the cushion 100 is laid on a seat such as a chair and seated is viewed from above.

  As shown in FIGS. 3A to 3D, when the cushion 100 is used in a state where the thick portion 110 occupies 1/4 of the seating surface, the laying direction is changed by rotating the cushion 100. By doing so, it is possible to select a portion with which the thick portion 110 abuts out of the starboard, port, right thigh, and left thigh.

  More specifically, as shown in FIG. 3A, by laying the cushion cushion 100 by rotating it about 90 ° clockwise from the state where the thick portion 110 abuts on the starboard portion, FIG. As shown in FIG. 4, the portion with which the thick portion 110 abuts can be changed to the port portion. Similarly, each time the cushion 100 is further rotated about 90 ° clockwise, the portion where the thick portion 110 abuts can be changed from the left hip to the left thigh, and from the left thigh to the right thigh. it can. That is, as shown in FIG. 3C, by laying the cushion cushion 100 by rotating it about 180 ° clockwise from the state in which the thick portion 110 is in contact with the starboard portion as shown in FIG. The part with which the thick part 110 abuts can be changed to the left thigh. Similarly, as shown in FIG. 3 (a), by laying the cushion cushion 100 by rotating it about 270 ° clockwise from the state in which the thick portion 110 is in contact with the starboard portion, it is shown in FIG. 3 (d). As shown, the portion where the thick portion 110 abuts can be changed to the right thigh.

  Thus, when attaching the adjustment member 20, without forming the thick part 110 only by the 1st thick part 111, and the thick part 110 occupies 1/4 of a seat surface, when using the cushion 100 Can adjust the direction in which the posture is corrected by selecting the portion with which the thick portion 110 abuts from the starboard, port, right thigh, and left thigh.

  Next, by inserting the adjusting member 20 into the gap 15 and causing the first thick part 111 and the second thick part 112 to cooperate with each other, the seat cushion 100 in a state where the thick part 110 occupies half of the seating surface. A mode in the case of using will be described in detail with reference to FIG.

  4 (a) to 4 (d) are schematic diagrams showing an aspect in the case where the cushion 100 is used in a state where the thick portion 110 occupies half of the seating surface. FIG. 4 also shows the state when the cushion 100 is laid on a seating surface of a chair or the like as seen in FIG. 3 as seen from above.

  As shown in FIGS. 4A to 4D, when the cushion 100 is used in a state where the thick portion 110 occupies half of the seating surface, the laying direction is changed by rotating the cushion 100. Thus, it is possible to select a portion to contact the thick portion 110 from the left and right hips, the left thigh and the left hip, the right thigh and the right hip, and the left and right thighs.

  More specifically, as shown in FIG. 4A, the cushion 100 is rotated about 90 ° clockwise from the state in which the thick portion 110 is in contact with both the left and right collars, and is laid. As shown in b), the part with which the thick part 110 abuts can be changed to the left thigh and port part. Similarly, each time the cushion 100 is further rotated about 90 ° clockwise, the portion where the thick portion 110 abuts is changed from the left thigh and the left hip to the left and right thighs, and from the left and right thighs to the right. It can be changed to the thigh and starboard.

  That is, as shown in FIG. 4A, by laying the cushion 100 by rotating it about 180 degrees clockwise from the state in which the thick portion 110 abuts on both the left and right collars, it is shown in FIG. 4C. In this way, the portion where the thick portion 110 abuts can be changed to the left and right thighs. Similarly, as shown in FIG. 4 (a), the cushion 100 is rotated about 270 ° clockwise from the state in which the thick portion 110 is in contact with both the left and right collars, so that FIG. As shown in FIG. 4, the portion where the thick portion 110 abuts can be changed to the right thigh and starboard.

  In this way, the adjustment member 20 is attached and the first thick part 111 and the second thick part 112 cooperate to form the thick part 110 so that the thick part 110 occupies half of the seating surface. By using the lever cushion 100, the portion with which the thick portion 110 abuts is selected from the left and right hips, the left thigh and the left hip, the right thigh and the right hip, and the left and right thighs. Then, the direction for correcting the posture can be adjusted.

  Further, the cushion 100 is used with the front (front) surface 31, that is, the second cushion member 12 side as the upper surface, and the back (back) surface 32, that is, the first cushion member 11 side, as the upper surface. A difference from the case of using will be described with reference to FIG.

  FIG. 5A shows the cushion 100 when it is laid with the front surface 31 as the upper surface, and FIG. 5B shows the cushion 100 when it is laid with the back surface 32 as the upper surface. Cross-sectional views are shown respectively.

  As shown in FIG. 5A, when the cushion cushion 100 is laid with the front surface 31 as the upper surface, the second cushion member 12 is on the upper side, and the fixing member 13 and the adjustment member A step between the thick portion 110 formed by the thickness of 20 and other portions appears on the seating surface via the second cushion member 12.

  On the other hand, when the cushion 100 is laid with the back surface 32 as the upper surface as shown in FIG. 5 (b), the first cushion member 11 is on the upper side, and the thick portion 110 and other parts A step with the part appears on the seating surface via the first cushion member 11.

  Since the first cushion member 11 is thicker than the second cushion member 12, as shown in FIG. 5B, the back (back) surface 32 is the upper surface, that is, via the first cushion member 11. When the seat cushion 100 is laid and seated so that the step of the thick portion 110 appears on the seating surface, the thick portion 110 and other portions are seated more than when seated with the front (front) surface 31 as the upper surface. A step with the part appears gently on the seat. In short, in this cushion 100, by selecting whether the front (front) surface 31 is the upper surface or the back (back) surface 32 is the upper surface when used, the thick portion 110 and others are selected. It is possible to select the degree of correction and the seating comfort, so-called feeling of use, which is caused by the size of the level difference from this part.

  Thus, according to the cushion 100 of this embodiment, by changing the laying direction, 4 patterns in the mode of only the first thick portion 111, and 4 patterns in the mode of attaching the adjustment member 20 are a total of 8 patterns. The correction direction can be selected, and the feeling of use in each pattern can be selected by properly using the front and back of the cushion 100, and the correction method can be adjusted in a total of 16 patterns.

According to the cushion 100 of the present embodiment described above, the following effects can be obtained.
(1) The seating surface is divided into four parts so as to correspond to the right thigh, the left thigh, the starboard part, and the left part with the center as the center, and one of the parts is more meat than the other part. The first thick portion 111 is thick. For this reason, as shown in FIGS. 3A to 3D, the first thick portion 111 is changed by changing the laying direction of the cushion 100, that is, by rotating the cushion 100 around the center of the seating surface. The abutting portion can be selected from the right thigh, left thigh, starboard, and port, and the direction of correcting the posture when seated can be adjusted. Moreover, since the adjustment member 20 which makes this site | part the 2nd thick part 112 detachable is provided in the site | part adjacent to the 1st thick part 111, by attaching the adjustment member 20, a 1st thickness is attached. The thick part 111 and the second thick part 112 can cooperate with each other, and two adjacent parts among the four parts can be used as the thick part 110. Even in the state where the adjustment member 20 is attached in this way, by rotating the cushion 100 around the center of the seating surface, the portions where the thick portion 110 abuts are located on both the left and right thighs and the right thigh. And the right hip, left and right hips, the left thigh, and the left hip. That is, according to the cushion 100 of the present embodiment, the direction in which the posture is corrected is selected in the form of 4 patterns in the form of only the first thick part 111, 4 patterns in the form of attaching the adjusting member 20, and the form of 8 patterns in total. Will be able to. This makes it possible to easily correct postures corresponding to different skeletal distortions and balances.

  (2) A seating surface is formed by stacking a pair of cushion members 11 and 12 and a fixing member 13 interposed between the pair of cushion members 11 and 12 to form the first thick portion 111. The configuration is adopted. According to such a configuration, the first thick portion 111 that is thicker than the other part due to the thickness of the fixing member 13 and the step between the other part and the other part do not appear directly on the seating surface. Can be better. Further, the second thick portion 112 can be formed by interposing the adjusting member 20 between the pair of cushion members 11 and 12.

  (3) Since the thicknesses T1 and T2 of the pair of cushion members 11 and 12 constituting the seat surface are different from each other, the cushion cushion 100 is fixed when the cushion cushion 100 is used with the thin second cushion member 12 as the upper surface. A step due to the thickness of the member 13 and the adjustment member 20 appears on the seating surface via the second cushion member 12 having the smaller thickness. Therefore, a difference in thickness between the thick portion 110 and other portions is likely to appear on the seating surface when seated. On the other hand, when the cushion 100 is used with the thicker first cushion member 11 as the upper surface, there is a step due to the thickness of the fixing member 13 and the adjustment member 20 via the thicker first cushion member 11. Appears on the seat. For this reason, when seated, the thickness difference between the thick portion 110 and other portions appears more gently on the seat surface than when the second cushion member 12 having the smaller thickness is placed on the upper surface. That is, by properly using the front and back sides of the cushion 100, it is possible to select the degree of correction and the comfort of sitting, so-called feeling of use.

  (4) The cushion 30 has a cover 30 provided with round marks 33 and 37 at positions corresponding to the first thick part 111 and square marks 34 and 38 at positions corresponding to the second thick part 112. It has. By using the cover 30 in such a state, the positions of the thick portions 111 and 112 can be visually recognized and the orientation of the cushion 100 can be determined.

  (5) The cover 30 has a front (front) surface 31 formed of a white fabric and a back (back) surface 32 formed of a black fabric. The front (front) surface 31 and the back ( Ura) The surface 32 has a different design. Thus, by using the cushion 100 in a state where the front (front) surface 31 and the back (back) surface 32 are put in the cover 30 having different designs, the difference between the front and back of the cushion 100 is visually discriminated. Will be able to.

In addition, the said embodiment can also be implemented with the following forms which changed this suitably.
In the above-described embodiment, the configuration in which the feeling of use is changed depending on the front and back of the cushion 100 by changing the thickness T2 of the first cushion member 11 and the thickness T1 of the second cushion member 12 has been described. It can replace with such a structure and can also employ | adopt the structure which forms each cushion member 11 and 12 by the elastic member from which an elastic coefficient differs, and changes a usability by the front and back of the cushion 100. FIG. According to such a configuration, in the case where the cushion cushion 100 is used with the softer cushion member having the smaller elastic coefficient, that is, the soft cushion member, the fixing member 13 and the adjusting member interposed between the pair of cushion members 11 and 12 are used. A step due to the thickness of 20 appears on the seating surface via the softer cushion member. Therefore, a difference in thickness between the thick portion 110 and other portions is likely to appear on the seating surface when seated. On the other hand, when using the cushion cushion 100 with the elastic member having a large elastic coefficient, that is, the hard cushion member as the upper surface, the step due to the thickness of the fixing member 13 and the adjustment member 20 is placed on the seat surface via the hard cushion member. appear. Therefore, when seated, the difference in thickness between the thick portion 110 and other parts appears more gently on the seat surface than when the harder cushion member is the upper surface.

  In addition, it is possible to adopt a configuration in which the hardness of each of the cushion members 11 and 12 is varied and the thickness is varied. In that case, one cushion member is formed thick with a hard member, while the other cushion member is thinly formed with a soft member, thereby suppressing an increase in the thickness of the cushion cushion 100 as a whole. The difference in the feeling of use due to the difference can be made clearer.

  On the other hand, the first cushion member 11 and the second cushion member 12 may be formed of the same material and have the same thickness. When such a configuration is adopted, it is impossible to select the feeling of use by properly using the front and back of the cushion 100, but at least the area of the thick portion 110 is changed by detaching the adjustment member 20, and the cushion 100 Can be rotated to adjust the direction of correction.

In the above embodiment, the thickness T3 of the fixing member 13 and the adjustment member 20 is set to the thickness of a palm, but this can be changed as appropriate.
-Although the structure which set to the thickness T3 of the fixing member 13 and the adjustment member 20 and made the thickness the same was shown, the thickness of the fixing member 13 and the adjustment member 20 may differ a little. For example, a configuration in which a plurality of types of adjusting members 20 having different thicknesses are provided and the thickness of the second thick portion 112 can be changed according to preference may be employed. However, by rotating the cushion 100, the fixing member 13 and the adjusting member are determined in order to determine the direction for correcting the posture when seated due to the difference in thickness between the thick portion 110 and other portions as a predetermined direction. It is desirable that the thickness 20 is set to be the same, and the thickness of the thick portion 110 is uniform.

  -Although the structure which attaches the adjustment member 20 to the main body 10 by inserting the adjustment member 20 in the clearance gap 15 formed between the 1st cushion member 11 and the 2nd cushion member 12 was shown, FIG. As indicated by the dashed line, the hook members 40, etc. may be provided on the cushion members 11, 12 and the adjustment member 20 as fixing fasteners.

  -Although the structure which forms the main body 10 by laminating | stacking so that the fixing member 13 may be pinched | interposed with the 1st cushion member 11 and the 2nd cushion member 12, you may abbreviate | omit one cushion member. That is, the fixing member 13 is fixed so as to protrude to one of the front surface and the back surface of the cushion member, the first thick portion 111 is formed, and the adjustment member 20 is provided on the surface from which the first thick portion 111 protrudes. The structure which forms the 2nd thick part 112 by attaching can also be employ | adopted. When one of the cushion members is omitted in this way, it is desirable to provide a surface fastener 40 or the like that holds the adjustment member 20 as described above.

  When such a configuration is adopted, when the cushion 100 is used with the surface formed so that the first thick portion 111 protrudes as the upper surface, the first thick portion 111 and the first thick portion 111 are used. A step due to the thickness of the second thick portion 112 appears directly on the seating surface. On the other hand, when the cushion 100 is used with the other surface as an upper surface, a step due to the thickness of the first thick portion 111 and the second thick portion 112 is seated through the flat surface of the cushion member. Appears on the surface. That is, even when such a configuration is adopted, it becomes possible to select a feeling of use by properly using the front and back of the cushion 100, and the correction method can be performed in a total of 16 patterns as in the above embodiment. Can be adjusted.

  In the above embodiment, the cover 30 is provided with the circle marks 33 and 37 and the square marks 34 and 38, and the first thick portion 111 and the second thick portion 112 are used as marks. The structure of these landmarks can be changed as appropriate, such as adding other patterns, making the fabric of the cover 30 different, changing the color, displaying by characters, attaching decorations such as ribbons and beads, etc. It is sufficient that the thick portions 111 and 112 can be discriminated.

  -Although the structure which attaches a different mark to the position corresponding to the 1st thick part 111 and the position corresponding to the 2nd thick part 112 was shown, respectively, even if these are the same marks, The position of the thick part 110 can be determined.

  -You may employ | adopt the structure which provides a mark in any one of the position corresponding to the 1st thick part 111, and the position corresponding to the 2nd thick part 112. FIG. In this case, it is desirable to employ a configuration in which a mark is provided at a position corresponding to the first thick portion 111 that is always thick.

-Moreover, you may employ | adopt the structure which does not provide such a mark.
In the above embodiment, the front (front) surface 31 of the cover 30 is formed of white fabric, while the back (back) surface 32 is formed of black fabric, so that the front (front) surface of the cushion 100 is formed. Although the structure which makes the design of 31 and the back (back) surface 32 different was shown, the material of the cover 30 which gives a different pattern by the front (front) surface 31 and the back (back) surface 32 is different. If it is possible to visually distinguish the front (front) surface 31 and the back (back) surface 32 of the cushion 100, such as display with characters, decoration such as ribbons and beads Good.

In addition, you may make the design of the front (front) surface 31 and the back (back) surface 32 of the cover 30 the same.
In addition, the cushion 30 may be configured by the main body 10 and the adjustment member 20 without providing the cover 30, and the cushion 100 may be used without the cover 30.

  In the above embodiment, the seat surface is divided into four equal parts about every 90 ° with the center at the center, and the fixing member 13 is fixed to one of the four divided portions. Is not necessarily divided into four equal parts around the center. However, if a configuration in which the seat is divided into four equal parts every 90 ° with the center of the seat surface as the center is adopted, the divided parts correspond to the starboard region, the left heel region, the right thigh region, and the left thigh region, respectively. Then, by rotating the cushion 100 by 90 °, the position where the thick portion 110 abuts can be appropriately changed.

  In the above-described embodiment, the mode of using the seat cushion 100 by laying it on the seat surface of a chair or the like has been described. However, other modes such as laying the seat cushion 100 directly on the floor and sitting on the floor, or an automobile seat It can also be used by laying it on.
