Summary of the Invention

Problems to be Solved by the Invention

[0004] By the way, when a user places their body on a cushion body such as the aforementioned pillow, as a result of the main body bag being compressed by the weight of the body, the contents such as feathers filled in the main body bag may move within the internal space of the main body bag. For example, it is easy for the contents to move from the part where the neck of the cushion body is placed to other parts. When the contents move excessively, the amount of the contents decreases in the part where the user's body is placed, so there is a concern that a part of the cushion body sinks too much and makes the user feel uncomfortable.

[0005] One approach is to restrict the movement of contents within the interior space by incorporating gussets that divide the interior space into multiple compartments. In particular, when a cushion has multiple gussets, the volume of the space where the contents are stored can be reduced, thus more effectively restricting the movement of the contents. However, a current problem is that when there are many gussets, the structure of the cushion becomes more complex, which can increase the manufacturing cost of the cushion.

[0006] This disclosure aims to provide a cushioning body that can suppress excessive movement of contents while suppressing an increase in manufacturing costs, and a method for manufacturing the cushioning body. [Means for solving the problem]

[0007] The cushion body according to this disclosure comprises (1) a bag-shaped cover, contents housed in the internal space of the cover, and a first gusset located in the internal space, wherein the first gusset has a partition portion that divides the internal space into multiple spaces, and a movement-restricting portion that extends from the partition portion toward the internal space and restricts the movement of the contents within the internal space.

[0008] In this cushion, the movement-restricting section extends outward from the partition section that divides the internal space into multiple compartments, and also restricts the movement of contents within the internal space. For example, when a user rests their neck on the cushion, the contents may move from the part of the cushion that supports the neck to the part that does not support the neck. At this time, the movement of at least a portion of the contents is restricted by the movement-restricting section. As a result, excessive movement of contents within the internal space can be suppressed, thereby reducing discomfort for the user. Furthermore, in this cushion, since the movement-restricting section of the first gusset restricts the movement of contents, there is no need to increase the number of gusset sections themselves. Therefore, the number of gusset sections can be reduced, thus suppressing an increase in the manufacturing cost of the cushion.

[0009] (2) In (1) above, the movement-restricting part may be a bag portion having an opening into which the moving contents enter. In this case, the contents moving in the internal space can be allowed to enter the bag portion through the opening, thereby trapping the contents inside the bag portion. This makes it possible to suppress the movement of the contents in the internal space even more reliably.

[0010] (3) In (2) above, the opening of the bag portion may be open toward the neck rest portion on which the user's neck rests. When the user of the cushion rests their neck on the neck rest portion, the contents move from the neck rest portion toward the portion other than the neck rest portion. Therefore, if the opening of the bag portion is open toward the neck rest portion, the contents moving away from the neck rest portion can be more reliably drawn into the bag portion through the opening. As a result, the movement of the contents from the neck rest portion can be suppressed, and discomfort when resting the neck can be further reduced.

[0011] (4) In any of (1) to (3) above, the outer fabric may be rectangular in shape, the first gusset may extend in the longitudinal direction of the outer fabric, and the movement-restricting portion may restrict the movement of the contents in a direction away from the neck rest portion on which the user's neck rests. In this case, when the user of the cushion rests their neck on the cushion, the movement of the contents in a direction away from the neck rest portion in the longitudinal direction of the outer fabric can be restricted.

[0012] (5) In any of (1) to (3) above, the cover fabric may be rectangular in shape, and the cushion body may have a pair of first gussets. The pair of first gussets may extend in the short direction of the cover fabric. One of the pair of first gussets may be provided on one side in the longitudinal direction of the cover fabric from the neck rest portion on which the user's neck rests. The other of the pair of first gussets may be provided on the other side in the longitudinal direction of the cover fabric from the neck rest portion. The movement restraint portion may restrain the movement of the contents in the direction away from the neck rest portion in the short direction. In this case, when the user of the cushion body places their neck on the cushion body, the movement of the contents in the direction away from the neck rest portion in the short direction can be restrained. In addition, the first gussets are provided on both one side and the other side in the longitudinal direction of the cover fabric as seen from the neck rest portion. This allows for a more balanced restraint of the movement of the contents in the internal space compared to, for example, a case where the first gussets are provided only on one or the other side in the longitudinal direction of the cover fabric as seen from the neck rest portion.

[0013] (6) In any of (1) to (3) above, the outer fabric may be rectangular in shape, and the cushion body may have a pair of first gussets. One of the pair of first gussets may be provided on one side in the longitudinal direction of the outer fabric from the neck rest portion on which the user's neck rests. The other of the pair of first gussets may be provided on the other side in the longitudinal direction of the outer fabric from the neck rest portion. The pair of first gussets may be spaced apart from each other in the longitudinal direction as they move away from the neck rest portion along the short direction of the outer fabric. The movement restraint portion may restrain the movement of the contents away from the neck rest portion. In this case, when the user of the cushion body places their neck on the cushion body, the movement of the contents away from the neck rest portion can be restrained. In addition, the first gussets are provided on one side and the other side in the longitudinal direction of the outer fabric as seen from the neck rest portion. This allows for a more balanced suppression of the movement of contents within the internal space compared to, for example, a case where the first gusset is provided only on one or the other side of the side fabric in the longitudinal direction when viewed from the neck rest.

[0014] (7) In any of (1) to (6) above, the cushion body may have a pair of ear rests. The pair of ear rests may be provided on one side and the other side in the longitudinal direction of the side fabric, as seen from the neck rest on which the user's neck rests. Each of the pair of ear rests may have a pair of second gussets separated in the short direction of the side fabric. In this case, when the user of the cushion body places their ears on the ear rests, the contents can be moved from the area between the pair of second gussets separated in the short direction to the other parts, so that the height of the ear rests can be lower than the height of the parts other than the ear rests. This prevents the ears from being compressed by the cushion body when the user places their ears on the ear rests.

[0015] A method for manufacturing a cushion body according to the present disclosure (8) A method for manufacturing a cushion body comprising a bag-shaped outer fabric including a first outer fabric and a second outer fabric, contents to be contained in the internal space of the outer fabric, and a gusset portion located in the internal space, comprising the steps of: creating a gusset portion having a partition portion that divides the internal space into a first internal space and a second internal space, and a movement-restricting portion that protrudes from the partition portion into the internal space and restricts the movement of the contents in the internal space; forming a first internal space defined by the first outer fabric and the gusset portion by sewing the gusset portion to one end and the other end of a curved first outer fabric; forming a second internal space defined by the second outer fabric and the gusset portion by sewing the curved second outer fabric to the gusset portion; and containing the contents in the first internal space and the second internal space.

[0016] In this method of manufacturing a cushion, a gusset is created that extends outward from a partition that divides the internal space into a first internal space and a second internal space, and includes a movement-restricting portion that suppresses the movement of contents within the internal space. The gusset with the movement-restricting portion is located within the internal space of the cushion. Therefore, in this method of manufacturing a cushion, similar to the cushion described above, the movement of at least a portion of the contents is suppressed by the movement-restricting portion, thus suppressing excessive movement of contents within the internal space. As a result, discomfort for the user of the cushion can be reduced. Furthermore, in this method of manufacturing a cushion, since the movement-restricting portion of the gusset suppresses the movement of the contents, similar to the cushion described above, there is no need to increase the number of gussets. Therefore, the number of gussets can be reduced, thereby suppressing an increase in the manufacturing cost of the cushion. [Effects of the Invention]

[0017] According to this disclosure, it is possible to suppress excessive movement of contents while keeping manufacturing costs down. [Brief explanation of the drawing]

Embodiments for Carrying Out the Invention

[0019] Hereinafter, embodiments of a cushion body and a method for manufacturing the cushion body according to the present disclosure will be described with reference to the drawings. In the description of the drawings, the same or corresponding elements are denoted by the same reference numerals, and redundant descriptions are omitted as appropriate. The drawings may be drawn with some parts simplified or exaggerated for ease of understanding, and dimensional ratios and the like are not limited to those described in the drawings.

[0020] The "cushion body" is composed of a flexible material. The "flexible material" refers to a cushioning material that deforms when the body is placed on it and receives a load. The flexible material is, for example, cloth. The cushion body is, for example, a pillow. The cushion body is not limited to a pillow and may also be a futon, a hanging futon, a zabuton, a mat, or a mattress.

[0021] The cushion body has a flexibility such that it deforms when the user's body is placed on it. The "user" is a person who uses the cushion body by bringing their own body into contact with the cushion body. For example, when the cushion body is a pillow, the user is a person who places their own body (e.g., the neck) on the pillow. The "user" is, for example, a person who lies on the purchased cushion body or a person who lies on the cushion body for the purpose of purchase.

[0022] The cushion body includes a bag-shaped outer fabric made of a flexible material and contents accommodated in the inner space of the outer fabric. The "outer fabric" refers to the bag-shaped fabric that constitutes the cushion body. The "contents" refers to what is accommodated in the inner space of the outer fabric to support the load of the user. The contents have, for example, a fluidity such that they can move in the inner space.

[0023] [First Embodiment] Figure 1 is a schematic plan view showing a cushion body 1 according to the first embodiment. Figure 2 is a cross-sectional view taken along line II-II in Figure 1. As shown in Figure 1, the cushion body 1 has a rectangular shape overall. The cushion body 1 extends in the longitudinal direction D1 and the transverse direction D2 perpendicular to the longitudinal direction D1. The cushion body 1 also has thickness in the thickness direction D3 perpendicular to both the longitudinal direction D1 and the transverse direction D2. In the example of Figure 1, the longitudinal direction D1 corresponds to the left-right direction of the paper, the transverse direction D2 corresponds to the up-down direction of the paper, and the thickness direction D3 corresponds to the direction perpendicular to the paper.

[0024] The length of the cushion body 1 in the longitudinal direction D1 is, for example, 30 cm or more and 80 cm or less (54 cm as an example). The length of the cushion body 1 in the short direction D2 is, for example, 20 cm or more and 60 cm or less (38 cm as an example).

[0025] In this embodiment, the cushion body 1 is a pillow. The user of the cushion body 1 places their head and neck on the cushion body 1. At this time, the direction in which the user's body lies (i.e., the direction connecting the user's head and legs) coincides, for example, with the shorter direction D2 of the cushion body 1. The cushion body 1 has a neck rest portion 11 on which the user's neck rests. In this embodiment, the neck rest portion 11 is located in the center of the longitudinal direction D1 of the cushion body 1 and to one side (downward in the example of Figure 1) of the center of the shorter direction D2 of the cushion body 1.

[0026] The cushion body 1 comprises a bag-shaped cover fabric 2. In this embodiment, the cover fabric 2 is rectangular in shape. The cover fabric 2 is, for example, opaque. The cover fabric 2 extends in the longitudinal direction D1 and the transverse direction D2. The cover fabric 2 has long sides 2a, 2b extending in the longitudinal direction D1 and short sides 2c, 2d extending in the transverse direction D2. The cover fabric 2 includes a first cover fabric 21 located on one side of the cover fabric 2 in the transverse direction D2 and a second cover fabric 22 located on the other side of the cover fabric 2 in the transverse direction D2. The first cover fabric 21 and the second cover fabric 22 are aligned in the transverse direction D2.

[0027] The longer sides 2a and 2b are bent in a V-shape in a plan view. The longer sides 2a and 2b are inclined with respect to the longitudinal direction D1 such that the distance between them decreases as they approach the center of the longitudinal direction D1 of the side fabric 2. The longer side 2a (the lower longer side in the example of Figure 1) extends from the shorter side 2c (the left shorter side in the example of Figure 1) toward the other side of the short direction D2 (the upper side in the example of Figure 1) as it approaches the center of the longitudinal direction D1 of the cushion body 1. Also, the longer side 2a extends toward one side of the short direction D2 (the lower side in the example of Figure 1) as it approaches the shorter side 2d (the right shorter side in the example of Figure 1) from the center of the longitudinal direction D1 of the cushion body 1. The longer side 2b (the upper longer side in the example of Figure 1) extends from the shorter side 2c toward one side of the short direction D2 as it approaches the center of the longitudinal direction D1 of the cushion body 1. Furthermore, the longer side 2b extends from the center of the longitudinal direction D1 of the cushion body 1 toward the other side of the shorter direction D2 as it moves toward the shorter side 2d. As a result, the shape of the side fabric 2 in plan view is a butterfly shape, where the length of the shorter direction D2 increases toward both ends of the longitudinal direction D1.

[0028] In the example shown in Figure 1, the short sides 2c and 2d are parallel to each other in a plan view. Each of the short sides 2c and 2d may extend in a straight line or be bent. An opening / closing member (not shown) for opening and closing the side fabric 2 may be provided on at least one of the short sides 2c and 2d. The opening / closing member is, for example, a linear fastener. The position where the opening / closing member is provided is not particularly limited.

[0029] As shown in Figure 2, the first outer fabric 21 and the second outer fabric 22 are bag-shaped. The first outer fabric 21 includes a first fabric portion 23 and a second fabric portion 24 that faces the first fabric portion 23 along the thickness direction D3. The first fabric portion 23 and the second fabric portion 24 are sewn together at one end (the left end in the example of Figure 2) in the short direction D2 of the cushion body 1. The sewn portion of the first fabric portion 23 and the second fabric portion 24 constitutes the long side 2a of the outer fabric 2.

[0030] The second outer fabric 22 includes a third fabric portion 25 and a fourth fabric portion 26 that faces the third fabric portion 25 along the thickness direction D3. The third fabric portion 25 and the fourth fabric portion 26 are sewn together at the other end of the cushion body 1 in the short direction D2 (the right end in the example of Figure 2). The sewn portion of the third fabric portion 25 and the fourth fabric portion 26 constitutes the long side 2b of the outer fabric 2.

[0031] The cushion body 1 includes a first gusset portion 4 located in the internal space S. The first gusset portion 4 divides the internal space S into multiple spaces. In this embodiment, the first gusset portion 4 divides the internal space S into a first internal space S1 and a second internal space S2. The first gusset portion 4 is a three-dimensional quilt. The first internal space S1 is defined by the first outer fabric 21 and the first gusset portion 4. The second internal space S2 is defined by the second outer fabric 22 and the first gusset portion 4.

[0032] The first gusset portion 4 is sewn to one end 21a and the other end 21b of the curved first outer fabric 21. The one end 21a of the first outer fabric 21 is, for example, the end of the first fabric portion 23 in the short direction D2 (the right end in the example of Figure 2). The other end 21b of the first outer fabric 21 is, for example, the end of the second fabric portion 24 in the short direction D2 (the right end in the example of Figure 2).

[0033] One end 22a and the other end 22b of the curved second fabric 22 are sewn to the first gusset portion 4. The one end 22a of the second fabric 22 is, for example, the end of the third fabric portion 25 in the short direction D2 (the left end in the example of Figure 2). The other end 22b of the second fabric 22 is, for example, the end of the fourth fabric portion 26 in the short direction D2 (the left end in the example of Figure 2).

[0034] As shown in Figure 1, in this embodiment, the first gusset portion 4 extends in the longitudinal direction D1. The first gusset portion 4 extends from the short side 2c to the short side 2d. The first gusset portion 4 curves toward the long side 2a as it moves from the short side 2c toward the center of the longitudinal direction D1 of the cushion body 1. Furthermore, the first gusset portion 4 curves toward the long side 2b as it moves from the center of the longitudinal direction D1 of the cushion body 1 toward the short side 2d.

[0035] The length of the first side fabric 21 in the shorter direction D2 gradually decreases from the shorter side 2c toward the neck rest portion 11 of the cushion body 1 (the center of the longitudinal direction D1 of the cushion body 1), and gradually increases from the neck rest portion 11 of the cushion body 1 toward the shorter side 2d. In other words, the width of the first side fabric 21 (length in the shorter direction D2) narrows as it approaches the center of the longitudinal direction D1 of the cushion body 1.

[0036] In this embodiment, the cushion body 1 includes an upper gusset portion 5 extending in the longitudinal direction D1 of the cover fabric 2. The upper gusset portion 5 is located in the center of the longitudinal direction D1 of the cover fabric 2 and on the opposite side from the neck rest portion 11 when viewed from the first gusset portion 4. The upper gusset portion 5 and the first gusset portion 4 are aligned, for example, along the short direction D2 of the cushion body 1. The upper gusset portion 5 is located in the second internal space S2. The upper gusset portion 5 connects the third fabric portion 25 and the fourth fabric portion 26 of the second cover fabric 22 to each other. Unlike the first gusset portion 4, the upper gusset portion 5 does not divide the internal space S of the cover fabric 2 into multiple spaces.

[0037] When the user's neck is placed on the neck rest 11, the position of the upper gusset portion 5 corresponds to the position where the user's occipital bone rests. Therefore, when the occipital bone rests on the cushion body 1, the contents may move from the part of the cushion body 1 that supports the occipital bone to the part that does not support the occipital bone. At this time, the upper gusset portion 5 suppresses the movement of the contents 3 in the short direction D2 in the part that supports the occipital bone. Note that the upper gusset portion 5 is not required.

[0038] The cushion body 1 comprises contents 3 housed in the internal space S (first internal space S1 and second internal space S2) of the cover fabric 2. For example, the contents 3 may be removable from the cover fabric 2. The contents 3 may be either hollow contents or solid contents. Hollow contents are contents with a hollow part, such as pipe material or beads. Solid contents are solid contents without a hollow part, such as buckwheat hulls, adzuki beans, cypress wood, or urethane chips. The contents 3 are fluid enough to be movable in the internal space S of the cover fabric 2. One example of contents 3 is pipe material. One example of pipe material is cylindrical in shape. In this case, the diameter of the pipe material is, for example, 1 mm or more and 10 mm or less (5 mm as an example). The material of the pipe material may be polyethylene, thermoplastic elastomer, polypropylene, or these materials that have been processed with tea kneading, binchotan charcoal kneading, etc. Tea-infused processing refers to processes such as kneading tea leaf extract into materials like polyethylene. Binchotan charcoal-infused processing refers to processes such as kneading finely powdered binchotan charcoal into materials like polyethylene. Thus, contents 3 may contain tea leaf extract or finely powdered binchotan charcoal, and the type, size, and materials of contents 3 can be changed as appropriate.

[0039] Figure 3 is a schematic perspective view of the first gusset portion 4 shown in Figure 2, viewed along the short side direction D2. In Figure 3, only the first gusset portion 4 of the cushion body 1 is shown, and the other components are omitted from the illustration. As mentioned above, the first gusset portion 4 divides the internal space S of the side fabric 2 into multiple spaces and is provided in the internal space S. As mentioned above, since the side fabric 2 is opaque, the first gusset portion 4 is not visible from the outside of the cushion body 1. The first gusset portion 4 extends in the longitudinal direction D1 and the thickness direction D3. The first gusset portion 4 has a partition portion 41 and a movement-restricting portion 42.

[0040] The partition 41 divides the internal space S into multiple spaces. The outer edge of the partition 41, as viewed from the short side direction D2, is sewn to the side fabric 2. The partition 41 has a narrow section 43 extending in the longitudinal direction D1 at the center of the longitudinal direction D1 of the first gusset section 4, and a pair of wide sections 44 provided at both ends of the narrow section 43 in the longitudinal direction D1 (left and right ends in the example of Figure 3).

[0041] The length of the narrow section 43 in the thickness direction D3 gradually decreases from one end of the narrow section 43 in the longitudinal direction D1 (the right end in the example of Figure 3) towards the center. The length of the narrow section 43 in the thickness direction D3 gradually increases from the center of the narrow section 43 in the longitudinal direction D1 towards the other end of the longitudinal direction D1 (the left end in the example of Figure 3). In other words, the width of the narrow section 43 (length in the short direction D2) narrows as it approaches the center of the narrow section 43 in the longitudinal direction D1.

[0042] Unlike the example in Figure 3, a portion of the wide portion 44 may have an elliptical shape. In this case, the wide portion 44 may have a gradually increasing portion where the length in the thickness direction D3 gradually increases from the end in the longitudinal direction D1 toward the center of the longitudinal direction D1, and a gradually decreasing portion where the length in the thickness direction D3 gradually decreases toward the center of the longitudinal direction D1. The gradually increasing portion constitutes both ends of the wide portion 44 in the longitudinal direction D1 (the left and right ends in the example in Figure 3). The gradually decreasing portion is located between the gradually increasing portion and the narrow portion 43.

[0043] The movement-restricting portion 42 protrudes from the partition portion 41 toward the internal space S. In this embodiment, the movement-restricting portion 42 protrudes from the partition portion 41 toward the first internal space S1. The movement-restricting portion 42 restricts the movement of the contents 3 in the internal space S. In this embodiment, the movement-restricting portion 42 is a bag portion 45 having an opening 46. The contents 3 that move in the internal space S enter into the opening 46 of the bag portion 45. Multiple bag portions 45 are provided (four as an example).

[0044] The opening 46 of the bag portion 45 opens toward the center of the longitudinal direction D1 of the first gusset portion 4. As mentioned above, the neck rest portion 11 is located in the center of the longitudinal direction D1 of the cushion body 1. That is, the opening 46 of the bag portion 45 opens toward the neck rest portion 11.

[0045] In this embodiment, the first gusset portion 4 that partitions the internal space S of the outer fabric 2 extends in the longitudinal direction D1. Therefore, when the user places their neck on the neck rest portion 11 of the cushion body 1, the contents 3 move in the direction D4 (see Figure 1) away from the neck rest portion 11 in the longitudinal direction D1. At this time, a part of the contents 3 enters the bag portion 45 through the opening 46, thereby suppressing the movement of the contents 3 in the internal space S. In this way, the movement suppression portion 42 suppresses the movement of the contents 3 in the direction D4 away from the neck rest portion 11 in the longitudinal direction D1.

[0046] Next, a method for manufacturing the cushion body 1 according to this embodiment will be described. First, as shown in Figures 4(a), 4(b), and 4(c), the first gusset portion 4 is made from the gusset fabric 51 (step for making the gusset portion). In this embodiment, the shape of the gusset fabric 51 is such that it is located in the center of the longitudinal direction D1 of the gusset fabric 51 and is symmetrical with respect to the line of symmetry L extending in the thickness direction D3. Therefore, in the examples of Figures 4(a) to 4(c), only one side of the longitudinal direction D1 of the gusset fabric 51 (the left side in the example of Figure 4(a)) is shown, and the other side of the longitudinal direction D1 of the gusset fabric 51 is omitted from the illustration.

[0047] In the process of creating the gusset, first, as shown in Figure 4(a), the gusset fabric 51, which is the material for the first gusset 4, is prepared. The gusset fabric 51 may be a single piece of fabric, or it may be made up of multiple pieces of fabric layered together. The gusset fabric 51 may be treated with an anti-slip finish. The gusset fabric 51 may be, for example, a fabric to which a resin of a predetermined height is attached. The height of this resin may be, for example, about 1 mm. Also, this resin may be attached to the fabric in a dot pattern, for example. The gusset fabric 51 may be, for example, a fabric that has been napped or textured. By using a gusset fabric 51 with an anti-slip finish, the movement of contents 3 in the internal space S can be further suppressed compared to when using a gusset fabric 51 without an anti-slip finish. The length D1 in the longitudinal direction of the gusset fabric 51 is longer than the length D1 in the longitudinal direction of the first gusset 4. The gusset fabric 51 has a wide section 44 and a narrow section 53 which constitutes a narrow section 43.

[0048] The length of the narrow portion 53 in the thickness direction D3 gradually decreases from one end of the narrow portion 53 in the longitudinal direction D1 (the left end in the example of Figure 4(a)) towards the center of the longitudinal direction D1. The length of the narrow portion 53 in the thickness direction D3 gradually increases from the center of the narrow portion 53 in the longitudinal direction D1 towards the other end of the longitudinal direction D1 (the right end in the example of Figure 4(a)).

[0049] Next, as shown in Figure 4(b), the narrow portion 53 is folded along the longitudinal direction D1. In the example in Figure 4(b), the narrow portion 53 is folded into thirds. As a result, a first folded portion 61 is formed in the folded part of the narrow portion 53, located towards the end of the longitudinal direction D1 of the narrow portion 53, and a second folded portion 62 is formed, located closer to the center of the longitudinal direction D1 of the narrow portion 53 than the first folded portion 61. In addition, an overlapping portion 63 is formed in which multiple (three in the example in Figure 4(b)) narrow portions 53 are stacked on top of each other.

[0050] Next, as shown in Figure 4(c), a bag portion 45 having an opening 46 is formed. Both ends of the overlapping portion 63 in the thickness direction D3 (the upper and lower ends in the example of Figure 4(b)) are folded toward the shorter direction D2. The bag portion 45 is formed by sewing these ends of the overlapping portion 63 to the narrow portion 53. The first folded portion 61 forms the bottom of the bag portion 45. The second folded portion 62 forms the opening 46 of the bag portion 45. By repeating the process shown in Figures 4(b) and 4(c), a first gusset portion 4 having multiple bag portions 45 is manufactured.

[0051] As shown in Figure 5(a), the first outer fabric 21 is then fabricated by sewing the first fabric portion 23 and the second fabric portion 24 together. The first gusset portion 4 fabricated above is then sewn to one end 21a and the other end 21b of the curved first outer fabric 21. For example, the first gusset portion 4 is sewn so that the bag portion 45 protrudes into the first internal space S1. By sewing the first gusset portion 4 to the first outer fabric 21, the first internal space S1 is formed by the first outer fabric 21 and the first gusset portion 4 (step of forming the first internal space).

[0052] Next, the second outer fabric 22 is made by sewing the third fabric portion 25 and the fourth fabric portion 26 together. Then, as shown in Figure 5(b), one end 22a and the other end 22b of the curved second outer fabric 22 are sewn to the first gusset portion 4. By sewing the second outer fabric 22 to the first gusset portion 4, a second internal space S2 is formed by the second outer fabric 22 and the first gusset portion 4 (step of forming the second internal space).

[0053] Next, as shown in Figure 5(c), the contents 3 are placed in the first internal space S1 and the second internal space S2 (the process of placing the contents). For example, the contents 3 may be placed into the internal space S via an opening / closing member provided on at least one of the short sides 2c, 2d of the outer fabric 2. After these steps, the series of steps for manufacturing the cushion body 1 according to this embodiment is completed.

[0054] The embodiments of the method for manufacturing a cushion body according to this disclosure have been described above. However, the content and order of each step in the method for manufacturing a cushion body according to this disclosure are not limited to the embodiments described above and can be modified as appropriate.

[0055] Next, the effects of the cushion body 1 and the method for manufacturing the cushion body 1 according to this embodiment will be described in detail. In the cushion body 1 according to this embodiment, the movement-restricting part 42 protrudes toward the internal space S from the partition part 41 that divides the internal space S into multiple spaces and suppresses the movement of the contents 3 within the internal space S. For example, when a user of the cushion body 1 rests their neck on the cushion body 1, the contents 3 may move from the part of the cushion body 1 that supports the neck to the part other than the part that supports the neck. At this time, the movement of at least a portion of the contents 3 is suppressed by the movement-restricting part 42. As a result, excessive movement of the contents 3 within the internal space S can be suppressed, thereby reducing discomfort for the user.

[0056] Furthermore, in this cushion body 1, the movement-restricting portion 42 of the first gusset portion 4 suppresses the movement of the contents 3, eliminating the need to increase the number of gusset portions themselves. In this embodiment, the gusset portion that divides the internal space S of the cushion body 1 is only one first gusset portion 4. Therefore, the number of gusset portions can be reduced, thus suppressing an increase in the manufacturing cost of the cushion body 1.

[0057] In the cushion body 1 according to this embodiment, as shown in Figure 3, the movement-restricting portion 42 is a bag portion 45 having an opening 46 into which the moving contents 3 enter. In this case, the contents 3 moving in the internal space S can be allowed to enter the bag portion 45 through the opening 46, thereby trapping the contents 3 inside the bag portion 45. This makes it possible to more reliably suppress the movement of the contents 3 in the internal space S.

[0058] In the cushion body 1 according to this embodiment, the opening 46 of the bag portion 45 opens toward the neck rest portion 11 on which the user's neck rests. When the user of the cushion body 1 rests their neck on the neck rest portion 11, the contents 3 move from the neck rest portion 11 toward the portion other than the neck rest portion 11. Therefore, if the opening 46 of the bag portion 45 opens toward the neck rest portion 11, the contents 3 moving from the neck rest portion 11 can be more reliably drawn into the bag portion 45 through the opening 46. As a result, the movement of the contents 3 from the neck rest portion 11 can be suppressed, and discomfort when resting the neck can be further reduced.

[0059] In the cushion body 1 according to this embodiment, the outer fabric 2 has a rectangular shape. The first gusset portion 4 extends in the longitudinal direction D1 of the outer fabric 2. The movement restraining portion 42 restrains the movement of the contents 3 in the direction away from the neck rest portion 11 on which the user's neck rests, in the longitudinal direction D1. In this case, when the user of the cushion body 1 rests their neck on the cushion body 1, the movement of the contents 3 in the direction away from the neck rest portion 11, in the longitudinal direction D1 of the outer fabric 2 can be restrained.

[0060] Furthermore, in the cushion body 1 according to this embodiment, multiple bag portions 45 are provided. In this case, since the first gusset portion 4 is provided with multiple bag portions 45 into which the moving contents 3 enter, the movement of the contents 3 in the internal space S can be suppressed even more reliably.

[0061] Furthermore, in the cushion body 1 according to this embodiment, as shown in Figure 1, the side fabric 2 has a rectangular shape with long sides 2a, 2b and short sides 2c, 2d. The side fabric 2 has a first side fabric 21 that includes the neck rest portion 11. The length of the first side fabric 21 in the short direction D2 gradually decreases from the short side 2c toward the neck rest portion 11 of the cushion body 1, and gradually increases from the neck rest portion 11 toward the short side 2d of the cushion body 1. That is, the width of the first side fabric 21 (length in the short direction D2) narrows toward the center of the longitudinal direction D1 of the first side fabric 21 (for example, the neck rest portion 11). In this case, the first internal space S1 formed by the first side fabric 21 narrows toward the neck rest portion 11. As a result, when the user of the cushion body 1 rests their neck on the neck rest portion 11, the shorter length D2 of the first outer fabric 21 around the neck rest portion 11 is narrower, which more effectively suppresses the movement of the contents 3 in the longer direction D1. Consequently, discomfort when resting the neck can be further reduced.

[0062] In this method of manufacturing the cushion body 1, as shown in Figures 5(a) to 5(c), a first gusset portion 4 is created that extends toward the internal space S from a partition portion 41 that divides the internal space S into a first internal space S1 and a second internal space S2, and includes a movement-restricting portion 42 that suppresses the movement of contents 3 within the internal space S. The first gusset portion 4 on which the movement-restricting portion 42 is formed is located in the internal space S of the cushion body 1. Therefore, in this method of manufacturing the cushion body 1, similar to the cushion body 1 described above, the movement of at least a portion of the contents 3 is suppressed by the movement-restricting portion 42, thus suppressing excessive movement of contents 3 within the internal space S. As a result, discomfort for the user using the cushion body 1 can be reduced.

[0063] Furthermore, in this method of manufacturing the cushion body 1, the movement-restricting portion 42 of the first gusset portion 4 restricts the movement of the contents 3, so, as with the cushion body 1 described above, there is no need to increase the number of gusset portions. Therefore, the number of gusset portions can be reduced, thereby suppressing an increase in the manufacturing cost of the cushion body 1.

[0064] [Second Embodiment] Next, the cushion body 1A according to the second embodiment will be described. In the following description, the differences from the cushion body 1 according to the first embodiment will be mainly described, and redundant explanations will be omitted as appropriate by using the same reference numerals.

[0065] As shown in Figure 6, the side fabric 2A of the cushion body 1A has a first side fabric 21A, a second side fabric 22A, and a third side fabric 23A. The first side fabric 21A, the second side fabric 22A, and the third side fabric 23A are arranged in this order along the longitudinal direction D1 of the side fabric 2A. The cushion body 1A has a pair of first gussets 4A and 4B instead of the first gusset 4.

[0066] The first gusset portions 4A and 4B extend in the short direction D2 of the side fabric 2A. The first gusset portion 4A is located on one side of the side fabric 2A in the longitudinal direction D1 (the left side in the example of Figure 6) relative to the neck support portion 11. The first gusset portion 4B is located on the other side of the side fabric 2A in the longitudinal direction D1 (the right side in the example of Figure 6) relative to the neck support portion 11.

[0067] Each of the first gusset sections 4A and 4B extends in the short direction D2 of the side fabric 2A, curving toward both ends of the longitudinal direction D1. That is, the first gusset sections 4A and 4B move further apart from each other as you move from one end of the short direction D2 of the side fabric 2A (the lower end in the example of Figure 6) toward the center of the short direction D2. Also, the first gusset sections 4A and 4B move closer to each other as you move from the center of the short direction D2 of the side fabric 2A toward the other end of the short direction D2 (the upper end in the example of Figure 6).

[0068] The first gusset sections 4A and 4B divide the interior space of the side panel 2A into multiple (three) spaces. The first gusset section 4A divides the interior space of the side panel 2A into the interior space of the first side panel 21A and the interior space of the second side panel 22A. The first gusset section 4B divides the interior space of the side panel 2A into the interior space of the second side panel 22A and the interior space of the third side panel 23A.

[0069] Each of the first gusset sections 4A and 4B has a movement-restricting section 42 that extends toward the space defined by the second side fabric 22A and the first gusset sections 4A and 4B. The movement-restricting section 42 restricts the movement of the contents 3 in the direction D5 away from the neck rest section 11 in the short-side direction D2.

[0070] The cushion body 1A has a lower gusset portion 5A that extends in the longitudinal direction D1 of the fabric cover 2A, instead of an upper gusset portion 5. The lower gusset portion 5A is located in the center of the longitudinal direction D1 of the fabric cover 2A, and to one side of the center of the short direction D2 of the fabric cover 2A. The lower gusset portion 5A is located in the space defined by the second fabric cover 22A and the first gusset portions 4A and 4B. Unlike the first gusset portions 4A and 4B, the lower gusset portion 5A does not divide the internal space of the fabric cover 2A into multiple spaces.

[0071] When the user's neck is placed on the neck rest 11, the position of the lower gusset portion 5A corresponds to the position where the area between the user's neck and the back of their head is placed. Therefore, when the user's body is placed on the cushion body 1, the lower gusset portion 5A suppresses the movement of the contents 3 in the short direction D2 at the part that supports the user's neck. The lower gusset portion 5A is optional.

[0072] Next, the effects of the cushion body 1A according to the second embodiment will be described in detail. In this embodiment, the side fabric 2A is rectangular in shape, and the cushion body 1A has first gussets 4A, 4B (a pair of first gussets). The first gussets 4A, 4B extend in the short direction D2 of the side fabric 2A. One of the first gussets 4A (one of the first gussets) is provided on one side of the side fabric 2A in the longitudinal direction D1 from the neck rest 11. The other gusset 4B (the other gusset) is provided on the other side of the side fabric 2A in the longitudinal direction D1 from the neck rest 11. The movement suppression part 42 suppresses the movement of the contents 3 in the direction D5 away from the neck rest 11 in the short direction D2.

[0073] In this case, when the user of the cushion body 1 rests their neck on the cushion body 1, the movement of the contents 3 in the direction D5 away from the neck rest portion 11 in the short direction D2 can be suppressed. Furthermore, a first gusset portion 4A is provided on one side of the longitudinal direction D1 of the side fabric 2A as viewed from the neck rest portion 11, and a first gusset portion 4B is provided on the other side of the longitudinal direction D1 of the side fabric 2A as viewed from the neck rest portion 11. This allows for a more balanced suppression of the movement of the contents 3 in the internal space S compared to, for example, a case where the first gusset portion is provided only on one or the other side of the longitudinal direction D1 of the side fabric 2A as viewed from the neck rest portion 11.

[0074] [Third Embodiment] Next, the cushion body 1B according to the third embodiment will be described with reference to Figure 7. As shown in Figure 7, the side fabric 2B of the cushion body 1B has a first side fabric 21B, a second side fabric 22B, and a third side fabric 23B. The cushion body 1B is equipped with a pair of first gussets 4C, 4D that are different from the first gusset 4.

[0075] Each of the first gusset portions 4C and 4D is formed in an arc shape in a plan view (viewed from the thickness direction D3). The first gusset portions 4C and 4D are spaced apart from each other in the longitudinal direction D1 as they move away from the neck support portion 11 along the short direction D2 of the side fabric 2. That is, the distance between the first gusset portions 4C and 4D increases as they move away from the neck support portion 11. The first gusset portion 4C is located on one side of the side fabric 2 in the longitudinal direction D1 relative to the neck support portion 11. The first gusset portion 4D is located on the other side of the side fabric 2 in the longitudinal direction D1 relative to the neck support portion 11.

[0076] The first gusset sections 4C and 4D divide the interior space of the side panel 2B into multiple (three) spaces. The first gusset section 4C divides the interior space of the side panel 2B into the interior space of the first side panel 21B and the interior space of the second side panel 22B. The first gusset section 4D divides the interior space of the side panel 2B into the interior space of the second side panel 22B and the interior space of the third side panel 23B.

[0077] Each of the first gusset sections 4C and 4D has a movement-restricting section 42 that extends toward the space defined by the second side fabric 22B and the first gusset sections 4C and 4D. Therefore, the movement-restricting section 42 suppresses the movement of the contents 3 in the direction D6 away from the neck rest section 11. Specifically, in the area where the neck rest section 11 is located, the first gusset sections 4C and 4D extend in the short-side direction D2 of the side fabric 2. Therefore, the movement-restricting section 42 suppresses the movement of the contents 3 in the direction D6 away from the neck rest section 11 in the short-side direction D2.

[0078] Furthermore, on the side opposite to the neck rest portion 11 in the short direction D2 of the cushion body 1 (the upper end side in the example of Figure 7), the first gusset portions 4C and 4D extend in the longitudinal direction D1 of the side fabric 2 while curving. For example, the movement restraining portion 42 restrains the movement of the contents 3 in the direction D7 away from the neck rest portion 11 in the longitudinal direction D1.

[0079] The cushion body 1B has ear rests 71 and 72. The ear rest 71 is provided on one side of the fabric 2B in the longitudinal direction D1 as viewed from the neck rest 11. The ear rest 71 is provided on the first fabric 21B. The ear rest 71 has second gussets 7 and 8 that are separated in the short direction D2 of the fabric 2B. The second gussets 7 and 8 extend in the longitudinal direction D1 of the fabric 2B. The distance from the second gusset 7 to the second gusset 8 is, for example, 3 cm or more and 15 cm or less.

[0080] The ear rest portion 72 is provided on the other side of the fabric 2B in the longitudinal direction D1 as viewed from the neck rest portion 11. The ear rest portion 72 is provided on the third fabric 23B. The ear rest portion 72 has second gusset portions 9 and 10 that are separated in the short direction D2 of the fabric 2B. The second gusset portions 9 and 10 extend in the longitudinal direction D1 of the fabric 2B. The distance from the second gusset portion 9 to the second gusset portion 10 is, for example, 3 cm or more and 15 cm or less.

[0081] The cushion body 1B has an upper gusset portion 5B that has a different shape from the upper gusset portion 5. The upper gusset portion 5B is curved so as it approaches the center in the longitudinal direction D1 of the cushion body 1B, it moves away from the neck rest portion 11. The upper gusset portion 5B is located in the space defined by the second side fabric 22B and the first gusset portions 4C and 4D. The upper gusset portion 5B suppresses the movement of the contents 3 in the short direction D2 within this space.

[0082] Next, the effects of the cushion body 1B according to the third embodiment will be described in detail. In the third embodiment, the side fabric 2B is rectangular in shape, and the cushion body 1B has first gussets 4C, 4D (a pair of gussets). The first gusset 4C (one gusset) is provided on one side of the side fabric 2B in the longitudinal direction D1 from the neck rest 11. The first gusset 4D (the other gusset) is provided on the other side of the side fabric 2B in the longitudinal direction D1 from the neck rest 11. The first gussets 4C, 4D move away from the neck rest 11 along the short direction D2 of the side fabric 2B and move away from the neck rest 11 in the longitudinal direction D1. The movement suppression part 42 suppresses the movement of the contents 3 in directions D6, D7 away from the neck rest 11.

[0083] In this case, when the user of the cushion 1B rests their neck on the cushion 1B, the movement of the contents 3 in directions D6 and D7 away from the neck rest 11 can be suppressed. Furthermore, a first gusset portion 4C is provided on one side of the longitudinal direction D1 of the side fabric 2B as viewed from the neck rest 11, and a first gusset portion 4D is provided on the other side of the longitudinal direction D1 of the side fabric 2B. This allows for a more balanced suppression of the movement of the contents 3 in the internal space compared to, for example, a case where the first gusset portion is provided only on one or the other side of the longitudinal direction D1 of the side fabric 2B as viewed from the neck rest 11.

[0084] The cushion body 1B has a pair of ear rests 71 and 72. The ear rest 71 is provided on one side of the fabric 2B in the longitudinal direction D1 as viewed from the neck rest 11. The ear rest 72 is provided on the other side of the fabric 2B in the longitudinal direction D1 as viewed from the neck rest 11. The ear rest 71 has a pair of second gussets 7 and 8 that are separated in the short direction D2 of the fabric 2B. The ear rest 72 has a pair of second gussets 9 and 10 that are separated in the short direction D2 of the fabric 2B.

[0085] In this case, when the user of the cushion body 1B places their ears on the ear rests 71 and 72, the contents 3 can be moved from the area between the second gusset sections 7 and 8 (or the area between the second gusset sections 9 and 10) which are separated in the short direction D2 to other areas. This allows the height of the ear rests 71 and 72 to be lower than the height of the other areas. As a result, when the user places their ears on the ear rests 71 and 72, the ears are not compressed by the cushion body 1B.

[0086] [Differentiation] The above describes various embodiments of the cushion body and the method for manufacturing the cushion body. However, the cushion body and the method for manufacturing the cushion body according to this disclosure are not limited to the embodiments described above and can be modified as appropriate. In this disclosure, multiple embodiments of the cushion body (first embodiment, second embodiment, and third embodiment) have been described. The cushion body according to this disclosure may be a cushion body formed by combining a part of an embodiment selected from the multiple embodiments with the remainder of an embodiment different from that embodiment. In other words, the contents of the first embodiment, second embodiment, and third embodiment described above can be extracted and combined as appropriate. For example, the cushion body 1 according to the first embodiment or the cushion body 1A according to the second embodiment may have the ear rest portions 71 and 72 described above.

[0087] For example, in the embodiment described above, an example was described in which the movement-restricting portion 42 is a bag portion 45. However, as shown in Figure 8(b), the movement-restricting portion 42 may be a cylindrical portion 81 that protrudes from the partition portion 41 toward the internal space S of the side fabric 2.

[0088] In preparing the first gusset portion 4 having the aforementioned cylindrical portion 81, first, as shown in Figure 8(a), a gusset fabric 51 is prepared having protruding portions 82 and 83 that extend from the partition portion 41 in opposite directions. Each of the protruding portions 82 and 83 extends in the thickness direction D3 from the narrow portion 53 of the gusset fabric 51. The shape of the protruding portions 82 and 83 is, for example, triangular, but is not particularly limited.

[0089] Next, as shown in Figure 8(b), the ends of the protruding portions 82 and 83 in the thickness direction D3 are sewn together. Through these steps, the first gusset portion 4 having the aforementioned tubular portion 81 is manufactured.

[0090] Alternatively, one end of the tubular portion 81 in the longitudinal direction D1 may be sewn to the narrow portion 53 to seal it and form a bag portion 45. In this case, the other end of the tubular portion 81 in the longitudinal direction D1 functions as the opening 46 of the bag portion 45.

[0091] In this modified cushion body 1, the movement-restricting portion 42 also suppresses the movement of the contents 3 in the internal space S. As a result, when the user of the cushion body 1 rests their neck on the cushion body 1, excessive movement of the contents 3 in the internal space S is suppressed, thereby reducing discomfort for the user. Furthermore, in this cushion body 1 as well, the movement-restricting portion 42 (cylindrical portion 81) of the first gusset portion 4 suppresses the movement of the contents 3, eliminating the need to increase the number of gusset portions themselves. Therefore, the number of gusset portions can be reduced, thus suppressing an increase in the manufacturing cost of the cushion body 1.

[0092] In the above-described embodiment, an example was explained in which the bag portion 45 is formed by folding and sewing the narrow portion 53 of the gusset fabric 51. However, as shown in Figure 9, the bag portion 45 may also be formed by sewing a tubular member 85 to the narrow portion 53 of the gusset fabric 51. Specifically, the bag portion 45 is formed by sewing one end of the tubular member 85 in the longitudinal direction D1 to the narrow portion 53. In this case, the other end of the tubular member 85 in the longitudinal direction D1 functions as the opening 46 of the bag portion 45.

[0093] In the cushion body 1 according to this modified example, a bag portion 45 having an opening 46 can be formed in the first gusset portion 4. In this case, the contents 3 moving in the internal space S can be allowed to enter the bag portion 45 through the opening 46, thereby trapping the contents 3 inside the bag portion 45. This makes it possible to more reliably suppress the movement of the contents 3 in the internal space S.

[0094] In the first embodiment described above, an example was described in which the movement-restricting portion 42 protrudes from the partition portion 41 toward the first internal space S1. However, the direction in which the movement-restricting portion 42 protrudes is not particularly limited. The movement-restricting portion 42 may protrude from the partition portion 41 toward the second internal space S2. In the second and third embodiments as well, the direction in which the movement-restricting portion 42 protrudes is not particularly limited.

[0095] In the first embodiment described above, an example was described in which the first gusset portion 4 has multiple pouch portions 45. However, the number of pouch portions 45 is not limited, and for example, there may be just one.

[0096] In the first and second embodiments described above, examples were explained in which each of the long sides 2a, 2b, 2c, and 2d of the outer fabric 2 is composed of a sewn portion of two fabric sections. For example, in the first and second embodiments, the long side 2a of the outer fabric 2 is composed of a sewn portion of a first fabric section 23 and a second fabric section 24. However, at least one of the long sides 2a, 2b, 2c, and 2d of the outer fabric 2 may be composed of a gusset section including a movement-restricting section 42. In this case, the movement-restricting section 42 protrudes, for example, from the outer fabric 2 toward the internal space S. In this case, the movement-restricting section 42 inside the outer fabric 2 suppresses the movement of the contents 3 in the internal space S. Furthermore, in the third embodiment as well, at least a part of the fabric constituting the outer fabric 2 may be composed of a gusset section including a movement-restricting section 42. Thus, the movement-restricting section 42 can be appropriately placed in the part where it is desired to suppress the movement of the contents 3.

[0097] Furthermore, the modified cushion body may include a seat portion that supports the user's shoulder blades, etc. The seat portion is formed to protrude in the short direction D2 from, for example, cushion body 1 shown in Figure 1, cushion body 1A shown in Figure 6, or cushion body 1B shown in Figure 7. The user's shoulders and back rest on this seat portion. Cushion bodies 1, 1A, and 1B equipped with this seat portion have the effect of providing a more comfortable sleeping experience by gently supporting the user's shoulders and back. The seat portion includes, for example, a sheet-like contents and a sheet-like cover that contains the contents. The sheet-like cover may be provided with an opening and closing member for opening and closing the sheet-like cover. The sheet-like contents are, for example, a urethane sheet, but may be something other than a urethane sheet. The material of the sheet-like cover may be the same as the material of the cover 2.

[0098] In the above-described embodiment, an example was given in which the outer fabric 2 is opaque. However, the outer fabric 2 of the cushion body may be transparent. In this case, the structure of the first gusset and the movement of the contents can be seen from the outside of the cushion body. For example, by displaying the cushion body 1 in the storefront of a bedding store, it can be seen that the movement of the contents is suppressed, and thus a promotional effect on customers can be expected.
