Description

[Technical Field]

[0001] FIELD The present disclosure relates to a cushion body having protrusions and a method for manufacturing the cushion body. [Background technology]

[0002] Various cushion bodies with protrusions have been known in the past. Registered Utility Model No. 3217333 describes a mattress-integrated pillow in which the mattress and pillow are integrally molded. The pillow has a protrusion for supporting the user's neck when lying on their back, and a recess located on the opposite side of the mattress across the protrusion. A raised portion is formed in the center vertical direction of the mattress, increasing its height on the upper side.

[0003] In plan view, the mat is trapezoidal and the pillow is rod-shaped. The convex portion of the pillow is rod-shaped. The convex portion has both side portions and a central portion, and the height of the both side portions is higher than the height of the central portion. In this integrated mattress pillow, the pillow, which has a convex portion with a central portion and both side portions higher than the central portion, and the mat are molded as a single unit, so that the entire pillow is an irregularly shaped cushion body. The integrated mattress pillow is made of a mixed material of gel and urethane, and its elasticity provides flexibility and resilience. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Registered Utility Model No. 3217333 Summary of the Invention [Problem to be solved by the invention]

[0005] Like the aforementioned mattress-integrated pillow, the cushion body with protrusions is manufactured by integral molding using a foam resin material such as urethane. Because this irregularly shaped cushion body is manufactured by integral molding, it is solidified while still having high elasticity. This type of cushion body is solid. Therefore, it may be prone to heat buildup due to poor breathability.

[0006] An object of the present disclosure is to provide a cushion body that can improve breathability and a method for manufacturing the cushion body. [Means for solving the problem]

[0007] The cushion body according to the present disclosure is a cushion body made of a flexible material. The cushion body includes a cushion body main body and a protrusion-forming fabric sewn to the outer surface of the cushion body to form a protrusion of the cushion body. Contents can be contained inside the protrusion of the cushion body formed by the protrusion-forming fabric. The cushion body has a rectangular shape in plan view. A plurality of protrusion-forming fabrics are arranged on one side of the cushion body in the short direction and on both ends of the cushion body in the longitudinal direction. Each of the plurality of protrusions has a protrusion that protrudes outward in the longitudinal direction of the cushion body from the end of the short side of the cushion body, and an apex located on the opposite side of the protrusion from the short side. The apex protrudes diagonally upward from a corner of the protrusion in plan view.

[0008] In this cushion, a protrusion-forming fabric that forms a protrusion of the cushion made of a flexible material is sewn into the outer surface of the cushion body main body. The protrusion-forming fabric is provided to form the protrusion of the cushion body, and forms the protrusion of the cushion body when sewn into the outer surface of the cushion body main body. The protrusion is capable of containing contents inside. Therefore, the protrusion is hollow, and since the hollow portion can contain contents, the breathability of the protrusion of the cushion body can be improved. In other words, unlike a solid, solid cushion, air can circulate inside, resulting in a cushion with good breathability. Furthermore, the protrusion of this cushion is formed by sewing the protrusion-forming fabric into the outer surface of the cushion body main body. Therefore, even when an external force is applied to the protrusion, the shape of the protrusion can be maintained.

[0009] The protrusion-forming fabric may be made up of multiple pieces of fabric. In this case, the protrusions can be formed by bonding multiple pieces of fabric together, which simplifies the shape of the fabric and more reliably maintains the shape of the protrusions.

[0010] child This allows the cushion body to be a pillow, and allows protrusions to be formed on both sides of the portion where the neck rests, so that the protrusions can fill the gap between the neck and the pillow when the cushion body user sleeps on their side, improving the comfort of sleeping on their side.

[0011] The contents may be hollow granular bodies. In this case, the hollow granular bodies are accommodated inside the protruding parts, so that the shape of the protruding parts can be maintained and the breathability of the protruding parts can be improved.

[0012] The method for manufacturing a cushion body according to the present disclosure is a method for manufacturing a cushion body made of a flexible material, and includes the steps of forming a cushion body main body, sewing a protrusion-forming fabric onto the outer surface of the cushion body to form a protrusion of the cushion body, and accommodating a content inside the protrusion of the cushion body. The cushion body has a rectangular shape in plan view. A plurality of protrusion-forming fabrics are arranged on one short-side side of the cushion body and on both longitudinal ends of the cushion body. Each of the plurality of protrusions has a protrusion that protrudes outward in the longitudinal direction of the cushion body from the end of the short side of the cushion body, and an apex located on the opposite side of the short side of the protrusion. The apex protrudes diagonally upward from a corner of the protrusion in plan view.

[0013] In this method of manufacturing a cushion body, a protrusion-forming fabric that forms a protrusion of a cushion body made of a flexible material is sewn onto the outer surface of the cushion body main body. The protrusion of the cushion body is formed by the protrusion-forming fabric sewn onto the outer surface of the cushion body main body, and contents are accommodated inside this protrusion. Therefore, the protrusion is hollow and can accommodate contents in the hollow portion, so that, similar to the cushion body described above, good breathability can be achieved in the protrusion. Furthermore, the protrusion is formed by sewing the protrusion-forming fabric onto the outer surface of the cushion body main body. Therefore, even if an external force is applied to the protrusion, the shape of the protrusion can be maintained. [Effects of the Invention]

[0014] According to the present disclosure, good breathability can be achieved. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0016] Hereinafter, embodiments of a cushion body and a method for manufacturing a cushion body according to the present disclosure will be described with reference to the drawings. In the description of the drawings, identical or corresponding elements are designated by the same reference numerals, and duplicate explanations will be omitted as appropriate. In addition, the drawings may be partially simplified or exaggerated for ease of understanding, and dimensional proportions and the like are not limited to those shown in the drawings.

[0017] The cushion body according to the present disclosure is made of a flexible material. "Flexible material" refers to a cushioning material that deforms when a body is placed on it and receives a load. The cushion body according to the present disclosure includes a cushion body main body. The "cushion body main body" refers to the main body of the cushion body, and refers to the part that functions as a cushion body even when it is the cushion body main body alone.

[0018] The cushion body according to the present disclosure includes a protrusion-forming fabric that forms a protrusion of the cushion body. "Protrusion" refers to a portion that protrudes from a location other than the protrusion of the cushion body. "Protrusion-forming fabric" refers to a fabric for forming the protrusion of the cushion body. Contents can be accommodated inside the protrusion of the cushion body. "Contents" refers to an object accommodated inside the cushion body, and may be, for example, a hollow content such as pipe material, a solid content such as buckwheat husks, adzuki beans, or cypress, or a flexible content such as cotton.

[0019] Fig. 1 is a plan view showing a cushion body 1 according to an embodiment. Fig. 2 is a bottom view of the cushion body 1. As shown in Fig. 1 and Fig. 2, the cushion body 1 according to the embodiment is a pillow having long sides 1b extending along a longitudinal direction D1 of the cushion body 1 and short sides 1c extending in a lateral direction D2 intersecting the longitudinal direction D1.

[0020] The cushion body 1 has a long side 1b and a pair of short sides 1c aligned along the longitudinal direction D1. The cushion body 1 has a convex portion 1d located on the opposite side of the long side 1b from the center C of the cushion body 1 in a plan view. In a plan view, the convex portion 1d protrudes outward in the short-side direction D2 of the cushion body 1. For example, the convex portion 1d is provided in a region including the center of the cushion body 1 in the longitudinal direction D1. For example, the convex portion 1d is rounded in a plan view.

[0021] The cushion body 1 has a protrusion 10 on one side in the short-side direction D2 and on both ends in the longitudinal direction D1. The protrusion 10 has a protruding portion 10b that protrudes outward in the longitudinal direction D1 of the cushion body 1 from the end of the short side 1c, an apex 10c that is located on the opposite side of the protruding portion 10b from the short side 1c, and an extending portion 10d that extends from the apex 10c to the convex portion 1d. The protrusion 10 will be described in detail later.

[0022] The cushion body 1 has a central portion 2 on which the user's back of the head is placed, and side portions 3 located on both sides of the central portion 2 in the longitudinal direction D1 and on which the user's sides of the head are placed. The central portion 2 has a first central portion 2b located on the opposite side of the convex portion 1d when viewed from the center C, and a second central portion 2c located between the first central portion 2b and the convex portion 1d.

[0023] The first central portion 2b corresponds to the portion on which the top of the user's head is placed, and the second central portion 2c corresponds to the portion on which the back of the user's head is placed. For example, the area of ​​the first central portion 2b is larger than the area of ​​the second central portion 2c. The convex portion 1d corresponds to the portion on which the user's neck is placed. The boundary line B1 between the first central portion 2b and the second central portion 2c, and the boundary line B2 between the second central portion 2c and the convex portion 1d are each sewn. For example, the boundary line B1 and the boundary line B2 extend along the longitudinal direction D1, and the length of the boundary line B1 is longer than the length of the boundary line B2. Each of the boundary lines B1 and B2 has a three-dimensional gusset.

[0024] The boundary line B3 between the side portions 3 and the central portion 2 extends in a direction inclined in both the longitudinal direction D1 and the lateral direction D2 from the corner 1f on the opposite side of the cushion body 1 from the protruding portion 10. The side portions 3 are made of, for example, a mesh material. In this case, good ventilation can be achieved for the sides of the user's head when lying on their side on the side portions 3.

[0025] For example, the outer edge of the protrusion 10 has, in addition to the overhanging portion 10b, the peak 10c, and the extending portion 10d, a first boundary portion 10f which is the boundary with the convex portion 1d, a second boundary portion 10g which is the boundary with the central portion 2, and a third boundary portion 10h which is the boundary with both side portions 3. The first boundary portion 10f, the second boundary portion 10g, and the third boundary portion 10h are curved so as to protrude toward the center C of the cushion body 1 in a plan view.

[0026] The first boundary 10f curves from the end of the extending portion 10d opposite the apex 10c toward the center in the longitudinal direction D1 and the center in the lateral direction D2. The second boundary 10g curves to protrude toward the center in the longitudinal direction D1 and the center in the lateral direction D2. The third boundary 10h connects the second boundary 10g and the protruding portion 10b to each other. For example, in a plan view, both side portions 3 have a triangular shape. The both side portions 3 are defined by the short side 1c, the boundary line B3, and the third boundary 10h.

[0027] The cushion body 1 has a lower surface portion 4 that faces downward. When the cushion body 1 is placed on bedding and used, the lower surface portion 4 comes into contact with the bedding. The lower surface portion 4 is made of, for example, a mesh material. For example, the lower surface portion 4 has a protrusion 4b located below the protrusion 1d, and the protrusion 4b protrudes outward in the short direction D2 at the center in the longitudinal direction D1.

[0028] The lower surface portion 4 has a protruding portion 4c that protrudes from the lower surface portion 4 and extends along the longitudinal direction D1, and can be opened and closed via the protruding portion 4c. Fig. 3 is a diagram showing the lower surface portion 4 in an open state. As shown in Figs. 2 and 3, the lower surface portion 4 is, for example, bag-shaped and can be opened and closed via the protruding portion 4c. For example, the lower surface portion 4 has a zipper 4d located inside the protruding portion 4c and can be opened and closed via the zipper 4d.

[0029] As shown in FIGS. 1 to 3, boundary line B1 separates the internal space of first central portion 2b from the internal space of second central portion 2c. However, boundary line B2 does not separate the internal space of second central portion 2c from the internal space of protruding portion 1d. Boundary line B3 does not separate the internal space of first central portion 2b from the internal spaces of both side portions 3. However, at first boundary line 10f, second boundary line 10g, and third boundary line 10h, the internal space of protruding portion 10 is separated from the internal spaces of portions of cushion body 1 other than protruding portion 10 (protruding portion 1d, central portion 2, and both side portions 3).

[0030] The inside of the lower surface portion 4 is provided with a central back side portion 6, which is the back side (lower side) of the first central portion 2b, a convex portion back side portion 7, which is the back side of the convex portion 1d, and a protrusion portion back side portion 11, which is the back side of the protrusion portion 10. For example, the inside of the central back side portion 6 is connected to the inside of the first central portion 2b and the inside of both side portions 3. The inside of the convex portion back side portion 7 is connected to the inside of the second central portion 2c and the inside of the convex portion 1d. The inside of the protrusion portion back side portion 11 is connected to the inside of the protrusion portion 10.

[0031] That is, the cushion body 1 has a first internal space S1 located inside the first central portion 2b and inside the side portions 3, a second internal space S2 located inside the second central portion 2c and inside the convex portions 1d, a third internal space S3 located inside the protruding portions 10 on one side in the longitudinal direction D1, and a fourth internal space S4 located inside the protruding portions 10 on the other side in the longitudinal direction D1. The central back side portion 6, the convex portion back side portions 7, and the protruding portion back side portions 11 each have a fastener 8.

[0032] For example, the cushion body 1 has four fasteners 8, and each fastener 8 opens and closes a first internal space S1, a second internal space S2, a third internal space S3, and a fourth internal space S4, respectively. Each of the first internal space S1, the second internal space S2, the third internal space S3, and the fourth internal space S4 is capable of containing an object 9.

[0033] The contents 9 are, for example, hollow granular materials. Specific examples of the contents 9 include pipe materials or beads. For example, the contents 9 may be cylindrical polyethylene pipe materials. However, the contents 9 may also be, for example, solid granular materials. Examples of solid granular materials include buckwheat husks, cypress, and adzuki beans.

[0034] Furthermore, the contents 9 may be made of a soft material including cotton (wadding) containing polyester granules, urethane, or feathers. In this way, various contents 9 can be put in and taken out of the first internal space S1, the second internal space S2, the third internal space S3, and the fourth internal space S4 by opening and closing the fasteners 8.

[0035] For example, a height adjustment sheet T for adjusting the height of the cushion body 1 can be inserted and removed from the inside of the bag-shaped lower surface portion 4. Fig. 4 is a diagram showing the height adjustment sheet T. As shown in Figs. 3 and 4, for example, the shape of the height adjustment sheet T in a plan view is similar to the shape of the cushion body 1 in a plan view. The height adjustment sheet T is made of, for example, urethane or solid cotton.

[0036] The following describes the configuration around the protrusion 10 according to this embodiment. Fig. 5 is a perspective view showing the protrusion 10. Fig. 6 is a view showing the protrusion 10 and both side portions 3. As shown in Figs. 1, 5, and 6, the both side portions 3 extend from the central portion 2 to the lower surface portion 4. Parts of the both side portions 3 form side surfaces located at both ends of the cushion body 1 in the longitudinal direction D1.

[0037] The cushion body 1 includes a protrusion-forming fabric 12 that forms the protrusion 10 of the cushion body 1. The protrusion-forming fabric 12 is sewn onto the outer surface of the cushion body main body 1A that is composed of the protrusion 1d, the central portion 2, and the side portions 3. In this embodiment, the protrusion-forming fabric 12 is sewn onto the outer surfaces of the protrusion 1d, the central portion 2, and the side portions 3. Inside the protrusion-forming fabric 12, contents 9 are accommodated.

[0038] The protrusion-forming fabric 12 is composed of a first fabric 13 facing upward, a second fabric 14 facing in the short-side direction D2, and a third fabric 15 facing in the long-side direction D1. The first fabric 13 has, for example, an elliptical shape (teardrop shape) in which one end along the major axis of the ellipse is deformed into a pointed apex 10c that protrudes along the major axis direction.

[0039] For example, the apex 10c protrudes obliquely upward from a corner of the protruding portion 10 in a plan view. In this case, when the user sleeps on their side with their head resting on the cushion body 1, the gap between the neck and the cushion body 1 can be filled, thereby protecting the neck and improving comfort when sleeping on one's side.

[0040] The second fabric 14 extends in the longitudinal direction D1 and along a height direction D3 of the cushion body 1. The height direction D3 is a direction intersecting both the longitudinal direction D1 and the lateral direction D2 and corresponds to the height direction of the cushion body 1 when the cushion body 1 is placed on bedding or the like. The second fabric 14 has a pair of protrusions 14b aligned along the height direction D3 at the end of the second fabric 14 in the longitudinal direction D1, and a constricted portion 14c extending in the height direction D3 between the pair of protrusions 14b and curved so as to protrude toward the center of the second fabric 14 in the longitudinal direction D1. A portion (lower portion) of the constricted portion 14c of the second fabric 14 is sewn to the both side portions 3, and a bottom edge 14d of the second fabric 14 extending in the longitudinal direction D1 is sewn to the underside portion 4.

[0041] The third fabric 15 has, for example, a triangular shape. A portion of the third fabric 15 is sewn into both side portions 3. For example, the third fabric 15 has a first side 15b sewn into both side portions 3, a second side 15c sewn into the first fabric 13, and a third side 15d sewn into the second fabric 14.

[0042] Next, an example of a manufacturing method of the cushion body 1 according to this embodiment will be described. FIGS. 7(a) and 7(b) are diagrams schematically showing one step of the manufacturing method of the cushion body 1. First, the cushion body main body 1A is formed. In this embodiment, the convex portion 1d, the central portion 2, and the side portions 3 are sewn together to manufacture the cushion body main body 1A. Then, the protrusion-forming fabric 12 is prepared (step of preparing the protrusion-forming fabric). In this embodiment, a first fabric 13, a second fabric 14, and a third fabric 15 are prepared. Then, the first fabric 13, the second fabric 14, and the third fabric 15 are sewn together to manufacture the protrusion-forming fabric 12.

[0043] The protrusion-forming fabric 12 is sewn onto the outer surface of the cushion body main body 1A to form the protrusion 10 of the cushion body 1 (protrusion forming step). After that, the fastener 8 (see FIG. 4) on the protrusion back side part 11 located on the back side of the protrusion 10 is opened and the contents 9 are placed inside the protrusion 10 (content placing step). After that, the series of steps in the manufacturing method of the cushion body 1 according to this embodiment is completed.

[0044] Next, the effects obtained from the cushion body 1 according to this embodiment and the manufacturing method of the cushion body 1 will be described. As shown in FIGS. 1, 5, and 6, in the cushion body 1, a protrusion-forming fabric 12 that forms the protrusion 10 of the cushion body 1 made of a flexible material is sewn onto the outer surface of the cushion body main body 1A. The protrusion-forming fabric 12 is provided to form the protrusion 10 of the cushion body 1, and forms the protrusion 10 of the cushion body 1 while being sewn onto the outer surface of the cushion body main body 1A. Contents 9 can be accommodated inside the protrusion 10. Therefore, the protrusion 10 is hollow, and the contents 9 can be accommodated in the hollow portion, thereby improving the breathability of the protrusion 10 of the cushion body 1.

[0045] That is, unlike cushion bodies made of solid, solidified molded urethane, air can circulate inside, making it possible to provide a cushion body 1 with good breathability while maintaining the shape of the protrusions 10. Furthermore, the protrusions 10 of the cushion body 1 are formed by sewing the protrusion-forming fabric 12 onto the outer surface of the cushion body main body 1A. Therefore, even when an external force is applied to the protrusions 10, the shape of the protrusions 10 can be maintained.

[0046] In this embodiment, the protrusion-forming fabric 12 is made up of multiple pieces of fabric (first fabric 13, second fabric 14, and third fabric 15). Therefore, the protrusion 10 can be formed by bonding multiple pieces of fabric together, which simplifies the shape of the fabric. Furthermore, the shape of the protrusion 10 can be more reliably maintained.

[0047] In this embodiment, the cushion body 1 has a rectangular shape in a plan view. A plurality of protrusion-forming fabrics 12 are arranged on one side of the cushion body 1 in the short direction D2 and on both ends of the cushion body 1 in the long direction D1. This allows the cushion body 1 of this embodiment, which is a pillow, to have protrusions 10 on both sides of the portion on which the neck is rested. Therefore, when the user of the cushion body 1 sleeps on their side, the protrusions 10 can fill the gap that forms between the neck and the pillow, thereby improving the sleeping comfort when sleeping on their side.

[0048] The contents 9 may be hollow granular bodies. In this case, the hollow granular bodies are housed inside the protrusions 10, so that the shape of the protrusions 10 can be maintained and the breathability of the protrusions 10 can be improved.

[0049] Next, a cushion body 21 according to a first modified example will be described with reference to Fig. 8. Various modified examples will be described below. Since part of the configuration of the cushion body according to each modified example described below overlaps with part of the configuration of the cushion body 1 described above, the description of the overlapping parts will be omitted as appropriate.

[0050] 8, the cushion body 21 includes a cushion body main body 21A and a protrusion-forming fabric 22 that is sewn onto the outer surface 21b of the cushion body main body 21A. The cushion body 21 includes a pair of protrusion-forming fabrics 22, and the cushion body main body 21A is provided between the pair of protrusion-forming fabrics 22.

[0051] As an example, the cushion body 21A has a rectangular parallelepiped shape. The cushion body 21A has a pair of main surfaces 21c on the front and back, and four side surfaces 21d that face in a direction intersecting the main surfaces 21c. The protrusion-forming fabric 22 is sewn into two of the four side surfaces 21d.

[0052] Fig. 9(a) is a perspective view showing the protrusion-forming fabric 22. As shown in Fig. 8 and Fig. 9(a), the protrusion-forming fabric 22 is composed of a first fabric 23, a second fabric 24 sewn to the first fabric 23, and a third fabric 25 sewn to the first fabric 23 and the second fabric 24.

[0053] For example, the first fabric 23 has a triangular shape. The second fabric 24 has a first side 24b sewn into the first fabric 23, a second side 24c sewn into the third fabric 25, and a third side 24d sewn into the cushion body main body 21A. The third fabric 25 has a first side 25b sewn into the first fabric 23, a second side 25c sewn into the second fabric 24, and a third side 25d sewn into the cushion body main body 21A. For example, the second fabric 24 and the third fabric 25 have shapes that are symmetrical to each other.

[0054] The first fabric 23, the second fabric 24, and the third fabric 25 configured as described above are sewn together to form the protrusion-forming fabric 22. The protrusion-forming fabric 22 is sewn into the outer surface 21b of the cushion body main body 21A to form the protrusion 21B of the cushion body 21.

[0055] For example, a zipper 26 is provided on any of the first fabric 23, the second fabric 24, and the third fabric 25. FIG. 9(a) shows an example in which the zipper 26 is provided on the second fabric 24. By opening the zipper 26, it becomes possible to store the contents 9 inside the protrusion-forming fabric 22.

[0056] As described above, in the cushion body 21 according to the first modified example, the protrusion-forming fabric 22 is sewn into the outer surface 21b of the cushion body main body 21A, and the contents 9 can be accommodated inside the protrusion 21B formed by the protrusion-forming fabric 22. Therefore, similar to the cushion body 1 described above, the shape of the cushion body 21 can be maintained while improving the breathability of the cushion body 21.

[0057] In the first modified example, the protrusion-forming fabric 22 is made up of three pieces of fabric, namely, the first fabric 23, the second fabric 24, and the third fabric 25. However, instead of the protrusion-forming fabric 22, a protrusion-forming fabric 22A made up of two pieces of fabric, namely, the first fabric 23, and a fourth fabric 27 in which the second fabric 24 and the third fabric 25 are integrally formed, may be used.

[0058] The cushion body 31 according to the second modification will be described with reference to Figures 10(a) and 10(b). As shown in Figure 10(a), the cushion body 31 includes a cushion body main body 31A and a protrusion-forming fabric 32 sewn into the outer surface 31b of the cushion body main body 31A.

[0059] The protrusion-forming fabric 32 forms a protrusion 31B that protrudes at an acute angle from the cushion body 31. For example, the cushion body main body 31A has a rectangular portion 31c and a trapezoidal portion 31d that is continuous with the rectangular portion 31c, and the protrusion-forming fabric 32 is sewn into a portion that corresponds to the oblique side of the trapezoidal portion 31d.

[0060] The protrusion-forming fabric 32 is composed of two pieces of fabric 33 each having a triangular shape with one rounded corner. The two pieces of fabric 33 have, for example, the same shape. The fabric 33 has a first side 33b sewn to the cushion body main body 31A and a second side 33c sewn to the other piece of fabric 33.

[0061] The protrusion-forming fabric 32 is formed into a bag shape by sewing two pieces of fabric 33 together, and the opening portion (the portion of a pair of first sides 33b) formed into the bag shape is sewn to the cushion body main body 31A. In addition, a zipper 36 is provided on one of the pair of fabrics 33, and by opening the zipper 36, it is possible to store contents 9 inside the protrusion-forming fabric 32.

[0062] A cushion body 41 according to a third modified example will be described with reference to Fig. 11(a). As shown in Fig. 11(a), the cushion body 41 includes a rectangular parallelepiped cushion body main body 41A and a protrusion-forming fabric 42 that forms a protrusion 41B that protrudes obliquely upward from the cushion body main body 41A.

[0063] For example, cushion body 41A has a main surface 41c on which the body rests and a side surface 41d facing in a direction intersecting with main surface 41c. Protrusion 41B has, for example, a butterfly shape that protrudes diagonally upward from main surface 41c. Protrusion-forming fabric 42 is composed of a first fabric 43 sewn onto main surface 41c of protrusion 41B, and a second fabric 44 sewn onto first fabric 43, the side surface 41d, and the underside (the surface facing away from main surface 41c) of cushion body 41.

[0064] For example, a zipper 46 is provided on the second fabric 44, and by opening the zipper 46, it is possible to store the contents 9 inside the protrusion-forming fabric 42. Note that, although Fig. 11(a) shows an example in which the protrusion-forming fabric 42 is sewn onto one side of the cushion body main body 41A, the protrusion-forming fabric 42 may be sewn onto both sides of the cushion body main body 41A.

[0065] A cushion body 51 according to a fourth modified example will be described with reference to Fig. 11(b). The cushion body 51 includes a cushion body main body 51A and a protrusion-forming fabric 52 sewn to an outer surface 51b of the cushion body main body 51A. The protrusion-forming fabric 52 is made of a single piece of fabric 53.

[0066] For example, fabric 53 is fan-shaped and sewn into cushion body main body 51A in a conical state. Fabric 53 has first side 53b where rolled pieces of fabric 53 are sewn together, and second side 53c where fabric 53 is sewn into cushion body main body 51A. First side 53b is linear, and second side 53c is arc-shaped.

[0067] For example, the space inside the protrusion-forming fabric 52 and the space inside the cushion body main body 51A are connected to each other. For example, the cushion body main body 51A is provided with a fastener 56, and by opening and closing the fastener 56, it is possible to store contents 9 inside the cushion body main body 51A and inside the protrusion-forming fabric 52. Cushion bodies according to various modifications have been described above, but cushion bodies according to these modifications can also achieve the same effects as the cushion body 1 described above.

[0068] The above describes embodiments and various modifications of the cushion body according to the present disclosure. However, the present disclosure is not limited to the above-described embodiments or modifications, and may be modified or applied to other things without departing from the spirit of the claims. In other words, the shape, size, material, number, and arrangement of each part of the cushion body, as well as the content and order of the steps in the manufacturing method of the cushion body, may be modified as appropriate without departing from the spirit of the present disclosure.

[0069] For example, in the above-described embodiment, an example was described in which the protrusion-forming fabric 12 is made up of three pieces of fabric, namely, the first fabric 13, the second fabric 14, and the third fabric 15, and in the above-described modified example, an example was described in which the protrusion-forming fabric 52 is made up of one piece of fabric 53. In this way, the number of pieces of fabric that make up the protrusion-forming fabric may be one, two, three, four or more, and can be changed as appropriate.

[0070] In the above embodiment, the cushion body 1 is described as a pillow. However, the cushion body according to the present disclosure may be something other than a pillow. For example, the cushion body may be a cushion, a floor cushion, a mattress, or other bedding, or a comforter.

[0071] In the above embodiment, an example has been described in which the cushion body 1 is manufactured by sewing the protrusion-forming fabric 12 that forms the protrusion 10 into the cushion body main body 1A. However, the protrusion-forming fabric may be sewn later onto an existing cushion body. In this case, the same effect as above can be obtained. Furthermore, the cushion bodies according to the embodiment and the first to fourth modified examples have been described above. Parts of these cushion bodies may be combined with other forms (modified examples). In this way, it is also possible to combine the cushion bodies according to the embodiment and the first to fourth modified examples. [Explanation of symbols]
