[Technical Field]

[0001] The present disclosure relates to bedding. [Background technology]

[0002] Patent Document 1 discloses a sleep device and a sleep system. This sleep device and sleep system include a body support unit that supports the user's body, sleep information detection means that detects the user's sleep information, a memory unit that stores the user's sleep information, exercise imparting means that causes the user's body to exercise, sleep state evaluation means that evaluates the user's sleep state based on the user's sleep information, and control means that can output a control method for the exercise imparting means based on the evaluation result of the sleep state evaluation means.

[0004] [Patent Document 1] Japanese Patent Application Publication No. 2019-150134 Summary of the Invention [Problem to be solved by the invention]

[0005] Like the sleep device with multiple air cells described above, bedding is known that has multiple airbags and controls the air supply to the multiple airbags to perform multiple stretching courses. However, while such bedding can perform multiple stretching courses, there is room for improvement in the accuracy of airbag inflation and deflation during each stretching course. This type of bedding is required to more accurately inflate and deflate the airbags to promote more comfortable sleep and awakening.

[0006] The present disclosure aims to provide bedding that can promote more comfortable falling asleep and waking up. [Means for solving the problem]

[0007] The stretch bedding according to the present disclosure comprises: (1) a bedding body having a thickness in a first direction, extending along a plane perpendicular to the first direction, and having a first surface on which a person's body rests; multiple airbags attached to the bedding body and performing operations including inflation by supplying air and deflation by exhausting air; a cover that houses the bedding body and the multiple airbags; an air control device connected to the multiple airbags and supplies and exhausts air to each of the multiple airbags; and a control unit that controls the supply and exhaust of air to the air control device. The multiple airbags inflate and deflate according to a first course and a second course organized by at least one operation mode defined by the number of operations, which is the number of times the multiple airbags operate, and the operation time, which is the time for each operation. The first course is executed when a person falls asleep. The second course is executed when a person wakes up. The control unit comprises a receiving unit that receives execution information indicating whether the first course or the second course should be executed, and an execution unit that causes the air control device to execute at least one of the first course and the second course in accordance with the execution information received by the receiving unit. The number of operation modes executed per unit time in the first course is less than the number of operation modes executed per unit time in the second course.

[0008] In this bedding, an airbag is attached to the bedding body. An air control device is connected to the airbag, and the airbag inflates by supplying air and deflates by exhausting air. The air control device controls the supply and exhaust of air to the airbag by a control unit. An operation mode is defined by the number of operations, which is the number of times the airbag operates, and the operation time, which is the time for the operation. The airbag included in this bedding operates according to an operation mode in which the number of operations and operation time are defined, thereby improving the accuracy of airbag inflation and deflation. A first course and a second course are organized according to the operation mode. The first course is executed when a person falls asleep, and the second course is executed when a person wakes up. The number of operation modes executed per unit time in the first course is less than the number of operation modes executed per unit time in the second course. As a result, the first course executed when falling asleep provides a stimulus that promotes relaxation to the person through slow movements, activating the person's parasympathetic nervous system and guiding the person smoothly into sleep. On the other hand, the second course, which is performed when waking up, stimulates the person with active movements and activates the person's sympathetic nerves. This helps the person to start being active immediately after waking up, and promotes awakening. Therefore, this bedding can promote more comfortable falling asleep and waking up.

[0009] (2) In the above (1), the bedding body may have a second surface facing the opposite side to the first surface and a first slit provided on the second surface. In this case, the first slit is provided on the second surface of the bedding body opposite the first surface on which the person's body rests, allowing the bedding body to deform locally. This allows the bedding body to deform locally and flexibly, making it easier for the deformation of the bedding body to follow the inflation of the airbag. For example, the bedding body can be placed in a state that surrounds the inflated airbag. This more reliably reduces discomfort for a person resting on the bedding body, facilitating more comfortable sleep and awakening.

[0010] (3) In the above (2), the air control device may have an air hose connected to each of the multiple airbags and supplying air to each airbag. At least a portion of the air hose may be provided within the first slit. In this case, providing at least a portion of the air hose within the slit reduces the amount of the air hose exposed on the surface of the bedding body. This prevents deformation of the bedding body due to the air hose exposed on the second surface, making it less likely for the person to feel uncomfortable and promoting more comfortable falling asleep and waking up.

[0011] (4) In any of the above (1) to (3), the bedding body may have a second slit on the first surface. In this case, the second slit is provided on the first surface of the bedding body on which the person's body rests, allowing the bedding body to deform locally. This allows the bedding body to deform locally and flexibly, making it easier for the deformation of the bedding body to follow the inflation of the airbag. For example, the bedding body can be placed in a state in which it surrounds the inflated airbag. This more reliably reduces discomfort felt by a person resting on the bedding body, facilitating more comfortable falling asleep and waking up.

[0012] (5) In any of the above (1) to (4), the upper part of the side fabric facing the first surface of the bedding body may be made of a stretchable material. The lower part of the side fabric, located on the opposite side of the bedding body from the multiple airbags, may be made of a non-stretchable material with lower stretchability than the stretchable material. The air control device may have an air hose connected to each of the multiple airbags and supplying air to each airbag. The air hose may be fixed to the lower part of the side fabric. In this case, since the upper part of the side fabric, which is the part that contacts the bedding body, is made of a stretchable material, the bedding body can easily flexibly follow the movements of the human body. This allows the bedding body to flexibly deform according to the shape of the human body. This reduces discomfort felt by the person, thereby promoting more comfortable falling asleep and waking up. Since the air hose is fixed to the lower part of the side fabric made of a non-stretchable material, the position of the air hose can be stabilized even when the person turns over in bed. This allows for a stable supply of air to the airbags.

[0013] (6) In any of the above (1) to (5), the thickness of the bedding body may be 3 cm or more and 15 cm or less. If the thickness of the bedding body is 3 cm or more, slits can be easily formed in the bedding body. If the thickness of the bedding body is 15 cm or less, the thickness of the bedding body can be prevented from becoming too thick.

[0014] (7) In any of the above (1) to (6), the bedding body may have an upper bedding and a lower bedding placed opposite the upper bedding. The plurality of airbags may be interposed between the upper bedding and the lower bedding. In this case, the bedding body and the plurality of airbags are integrated. This makes it easier to manage the bedding. [Effects of the Invention]

[0015] According to the present disclosure, it is possible to promote more comfortable falling asleep and waking up. [Brief explanation of the drawings]

[0017] Hereinafter, an embodiment of bedding 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 designated by the same reference numerals, and duplicate explanations will be omitted as appropriate. The drawings may be partially simplified or exaggerated for ease of understanding, and the dimensional proportions and the like are not limited to those shown in the drawings.

[0018] (First embodiment) FIG. 1 is a perspective view showing bedding 1 according to the first embodiment. FIG. 2 is an exploded perspective view showing bedding 1 according to the first embodiment. As shown in FIGS. 1 and 2, the bedding 1 comprises a mattress 20 (bedding main body) and an airbag 30. In addition to the mattress 20 and the airbag 30, the bedding 1 also comprises, for example, a bed frame 2 and a base mattress 3. In this embodiment, the mattress 20, the airbag 30 and the base mattress 3 form a bed frame. The bed frame 2 forms a bed support platform.

[0019] In the following description, the longitudinal direction of the bedding 1 is referred to as the longitudinal direction D1, the width direction of the bedding 1 as the width direction D2 (second direction), and the height direction of the bedding 1 as the height direction D3 (first direction). For example, the longitudinal direction D1 and the width direction D2 are horizontal directions, and the height direction D3 is vertical. For example, the longitudinal direction D1, the width direction D2, and the height direction D3 are perpendicular to one another.

[0020] The bed frame 2 has a rectangular parallelepiped shape. The length of the bed frame 2 in the longitudinal direction D1 is longer than the length of the bed frame 2 in the width direction D2. The length of the bed frame 2 in the width direction D2 is longer than the length of the bed frame 2 in the height direction D3. The bed frame 2 is placed on the floor surface on which the bedding 1 is placed. An indirect lighting device (not shown) may be provided between the bottom surface of the bed frame 2 and the floor surface.

[0021] The bed frame 2 has a headboard 2a. The headboard 2a is provided at one end of the bed frame 2 in the longitudinal direction D1. The headboard 2a protrudes from the mattress 20 in the height direction D3.

[0022] The base mattress 3 is placed on the bed frame 2. The base mattress 3 has a rectangular parallelepiped shape with a thickness in the height direction D3. The length of the base mattress 3 in the longitudinal direction D1 is longer than the length of the base mattress 3 in the width direction D2. The length of the base mattress 3 in the width direction D2 is longer than the length of the base mattress 3 in the height direction D3. The base mattress 3 has a flat surface extending along both the longitudinal direction D1 and the width direction D2.

[0023] The airbag 30 performs operations including inflation by air supply and deflation by air exhaust. The airbag 30 is provided on the base mattress 3. The airbag 30 may be detachable from the base mattress 3. Alternatively, the airbag 30 may be fixed to the base mattress 3. The airbag 30 is provided between the center of the base mattress 3 and the end of the base mattress 3 in the longitudinal direction D1. The airbag 30 is arranged in a portion that comes into contact with the waist and back of a person when the person is lying on the bedding 1.

[0024] The airbag 30 has, for example, a rectangular parallelepiped shape. The length of the airbag 30 in the longitudinal direction D1 is longer than the length of the airbag 30 in the width direction D2. The length of the airbag 30 in the width direction D2 is longer than the length of the airbag 30 in the height direction D3. The length of the airbag 30 in the longitudinal direction D1 is, for example, not less than 70 cm and not more than 90 cm. The width of the airbag 30 in the width direction D2 is, for example, not less than 30 cm and not more than 60 cm.

[0025] The bedding 1 has a rug 35 interposed between the airbag 30 and the base mattress 3. The rug 35 functions as a base on which the airbag 30 is placed. The rug 35 may be fixed to the base mattress 3 or may be detachable from the base mattress 3. The rug 35 extends in both the longitudinal direction D1 and the width direction D2. The rug 35 has a rectangular shape with long sides extending along the longitudinal direction D1 and short sides extending along the width direction D2. The airbag 30 is fixed to the rug 35, for example. If the airbag 30 is fixed to the rug 35 and the rug 35 is detachable from the base mattress 3, the airbag 30 can be easily attached and detached.

[0026] FIG. 3 is a plan view showing the airbag 30. The airbag 30 is attached to the mattress 20, which will be described in detail later. The airbag 30 is bag-shaped. The airbag 30 is filled with air by air supply and expands. The airbag 30 is deflated by air exhaust.

[0027] For example, the bedding 1 has a plurality of airbags 30. In this embodiment, the bedding 1 has three airbags 30. For example, the plurality of airbags 30 includes an airbag 31 that acts on the chest region and an airbag 32 that acts on the waist region. As an example, the plurality of airbags 30 includes one airbag 31 and two airbags 32. In the following description, when it is not necessary to distinguish between the airbag 31 and the airbag 32, the airbag 31 and the airbag 32 will be collectively referred to as airbag 30.

[0028] The airbag 31 is aligned with the chest of a person lying on the bedding 1 in the height direction D3. The airbag 32 is aligned with the waist of a person lying on the bedding 1 in the height direction D3. The airbag 31 is adjacent to two airbags 32 in the longitudinal direction D1. Each of the airbags 31 and 32 is bag-shaped.

[0029] The airbag 31 extends from one end in the longitudinal direction D1 of an area formed by the plurality of airbags 30 (a vertically elongated rectangular area in FIG. 3 ) to the center in the longitudinal direction D1. The airbag 31 extends across substantially the entire width direction D2 of the area. The airbag 31 has a portion (portion “A” in FIG. 3 ) aligned with the right chest of a person lying on their back on the bedding 1 in the height direction D3, and a portion (portion “D” in FIG. 3 ) aligned with the left chest of a person lying on their back on the bedding 1 in the height direction D3. In this embodiment, portion “A” and portion “D” are integrated. The airbag 31 may be a portion that contacts a person's back when the person lies on their back on the mattress 20. The length of the airbag 31 in the longitudinal direction D1 is, for example, 30 cm or more and 50 cm or less. The length of the airbag 31 in the width direction D2 is, for example, 40 cm or more and 60 cm or less.

[0030] The airbag 32 is provided, for example, in a portion other than the airbag 31 in the area formed by the plurality of airbags 30. The airbag 32 is arranged so as to surround the airbag 31 when viewed from the height direction D3. The two airbags 32 are lined up along the width direction D2. The airbags 32 are lined up with the waist of a person lying on the bedding 1 in the height direction D3.

[0031] In FIG. 3, the two airbags 32 are indicated as "B" and "C", respectively. The airbag 32 designated as "B" is aligned with the right hip of a person lying on their back on the bedding 1 in the height direction D3. The airbag 32 designated as "C" is aligned with the left hip of a person lying on their back on the bedding 1 in the height direction D3. The airbag 32 may be the part that comes into contact with the person's hips when the person is lying on the mattress 20.

[0032] For example, the airbag 32 has a portion 321 that is aligned with the airbag 31 in the longitudinal direction D1, and a portion 322 that is aligned with the airbag 31 in the width direction D2. The airbag 32 has, for example, two portions 321 and two portions 322. The portion 321 is adjacent to the airbag 31 in the longitudinal direction D1. The portion 321 extends in the longitudinal direction D1 from the end of the region formed by the multiple airbags 30 opposite the airbag 31 to the center of the region.

[0033] The portion 322 is adjacent to the airbag 31 in the width direction D2. The two portions 322 are arranged, for example, at both ends in the width direction D2 of an area formed by a plurality of airbags 30. The two portions 322 are arranged at positions sandwiching the airbag 31 in the width direction D2. That is, the portion 322, the airbag 31, and the portion 322 are lined up in this order in the width direction D2. Note that the dashed lines shown in FIG. 3 are lines indicating the portions 321 and 322, and the dashed lines do not physically separate the portions 321 and 322. That is, the portions 321 and 322 are integrated with each other.

[0034] The length of the portion 321 in the longitudinal direction D1 is, for example, 20 cm or more and 40 cm or less. The length of the portion 321 in the width direction D2 is, for example, 15 cm or more and 35 cm or less. The length of the portion 322 in the longitudinal direction D1 is, for example, 40 cm or more and 60 cm or less. The length of the portion 322 in the width direction D2 is, for example, 2 cm or more and 20 cm or less. The portion 321 of the airbag 32 and the portion 322 of the airbag 32 are aligned along the longitudinal direction D1.

[0035] In the longitudinal direction D1, the end 31b of the airbag 31 opposite to the airbag 32 is disposed at a position, for example, 20 cm or more and 40 cm or less, away from the headboard 2a (see FIG. 1). In this way, the airbag 30 is disposed at a position away from the headboard 2a in the longitudinal direction D1.

[0036] The airbag 30 has a non-inflatable portion 37. An air hose 51, which will be described later, is not connected to the non-inflatable portion 37. Therefore, the non-inflatable portion 37 is a portion of the airbag 30 that does not inflate when air is supplied. The non-inflatable portion 37 is provided between the airbag 31 and the airbag 32 in the longitudinal direction D1. The non-inflatable portion 37 is provided in the center of the airbag 30 when viewed along the height direction D3. The non-inflatable portion 37 is a portion that is aligned with the abdomen of the person when the person is resting on the mattress 20. The non-inflatable portion 37 can prevent the person's body from moving significantly due to the operation of the airbag 30, thereby stabilizing the person's body.

[0037] The bedding 1 has an air hose 51 through which air passes to the airbag 30. In the airbag 32, the air hose 51 is attached to a portion 322 on the opposite side of the portion 321 (upper side in FIG. 3). For example, one air hose 51 is connected to one portion 322. In the airbag 31, the air hose 51 is attached to a portion on the opposite side of the portion 321 (upper side in FIG. 3). For example, two air hoses 51 are attached to the airbag 31. When air is supplied from the air hose 51, each of the airbag 31 and the airbag 32 inflates. When air is exhausted to the air hose 51, each of the airbag 31 and the airbag 32 deflates.

[0038] The airbags 30 (airbags 31 and 32) can be stopped after air supply and maintained in the supplied state without being exhausted. This allows the airbags 30 to maintain an inflated state. In this way, stopping the airbags 30 after air supply creates a state in which the mattress 20 is locally raised in the height direction D3. This allows the mattress 20 to be inclined. If the mattress 20 has an inclination, it becomes easier for people with reflux esophagitis or elderly people with hunched backs to use the bedding 1.

[0039] The mattress 20 will be described with reference to Figure 2 again. The mattress 20 is a bedding body on which a person's body rests. The mattress 20 has a thickness in the height direction D3. The mattress 20 extends along a plane perpendicular to the height direction D3, and has a surface 21 (first surface) on which the person's body rests.

[0040] The mattress 20 has a rectangular parallelepiped shape. The length of the mattress 20 in the longitudinal direction D1 is longer than the length of the mattress 20 in the width direction D2. The length of the mattress 20 in the width direction D2 is longer than the length of the mattress 20 in the height direction D3. Furthermore, the mattress 20 of the bedding 1 has a back surface 22 (second surface) that faces the opposite side to the front surface 21 in the height direction D3. The back surface 22 of the mattress 20 faces the airbag 30.

[0041] The mattress 20 is placed on the base mattress 3 and the airbag 30. The bedding 1 has a first portion in which the mattress 20, airbag 30, rug 35, base mattress 3, and bed frame 2 are arranged in this order along the height direction D3, and a second portion in which the mattress 20, rug 35, base mattress 3, and bed frame 2 are arranged in this order along the height direction D3. The second portion differs from the first portion in that it does not have the airbag 30. A portion of the back surface 22 of the mattress 20 is in contact with the airbag 30. The airbag 30 is interposed between the mattress 20 and the rug 35.

[0042] When viewed from the height direction D3, the length of the mattress 20 in the longitudinal direction D1 is, for example, 180 cm or more and 210 cm or less. When viewed from the height direction D3, the length of the mattress 20 in the width direction D2 is, for example, 90 cm or more and 110 cm or less. The thickness of the mattress 20 is, for example, 3 cm or more and 15 cm or less. The material of the mattress 20 is, for example, polyurethane.

[0043] When a person stands on the mattress 20, a load is applied to the mattress 20. When the airbag 30 is inflated, the internal pressure of the airbag 30 that is under this load increases. As a result, the weight of the person standing on the mattress 20 and the pressure from the airbag 30 are applied to the mattress 20 in the height direction D3. Therefore, the hardness of the mattress 20 becomes harder in the part where the person stands on the mattress 20.

[0044] Fig. 4 is a cross-sectional view of the bedding 1 taken along a plane perpendicular to the longitudinal direction D1. For convenience, the bed frame 2, base mattress 3, and air hose 51 are not shown in Fig. 4. The bedding 1 includes a cover 40. The cover 40 is bag-shaped.

[0045] The cover 40 accommodates the mattress 20, the airbag 30, and the rug 35. The cover 40 unites the mattress 20, the airbag 30, and the rug 35. For example, the cover 40 has an opening and closing member that allows the cover 40 to be opened and closed. The opening and closing member is, for example, a zipper. The cover 40 may be configured so that the mattress 20, the airbag 30, and the rug 35 can be taken in and out by opening and closing the opening and closing member. The cover 40 may be fabric that covers the mattress 20, or may be fabric that covers a futon.

[0046] The length of the side fabric 40 in the longitudinal direction D1 is longer than the length of the side fabric 40 in the width direction D2. The length of the side fabric 40 in the longitudinal direction D1 is longer than the length of the mattress 20. The length of the side fabric 40 in the width direction D2 is longer than the length of the mattress 20.

[0047] The side fabric 40 has an upper portion 41 on which a person's body rests. The upper portion 41 faces the surface 21 of the mattress 20. The upper portion 41 of the side fabric 40 facing the surface 21 of the mattress 20 is made of a stretchable material. Therefore, the side fabric 40 facing the surface 21 on which a person's body rests is easily stretchable. When a person rests on the mattress 20, the upper portion 41 of the side fabric 40 easily deforms to match the shape and movement of the person's body.

[0048] "Stretchable material" refers to a material with a stretch rate of at least a certain value. "Stretch rate" refers to a numerical value that indicates how much a fabric stretches and shrinks. The stretch rate is generally expressed as a percentage. In this embodiment, the stretchable material is a fabric with a stretch rate of at least 15% and at most 100%.

[0049] For example, the upper part 41 is made of a stretchable material. However, a portion of the upper part 41 may be made of a stretchable material, and the remaining portion of the upper part 41 may be made of a non-stretchable material, as described below. The material of the upper part 41 is, for example, polyester, polyurethane, cotton, rayon, acrylic, silk, wool, or a blend thereof. The stretchable material is, for example, knit.

[0050] The lower portion 42 of the side fabric 40 is located on the opposite side of the mattress 20 from the airbag 30. The lower portion 42 of the side fabric 40 is made of a non-stretchable material that is less stretchable than a stretchable material. "Non-stretchable material" means a material whose stretch rate is less than a certain value. The lower portion 42 may be made of a non-stretchable material. However, a portion of the lower portion 42 may be made of a non-stretchable material, and the remaining portion of the lower portion 42 may be made of a stretchable material. The lower portion 42 is not limited to the above example and may also be made of a stretchable material. The non-stretchable material is, for example, a non-woven fabric. This non-woven fabric is, for example, felt. However, the non-stretchable material may be something other than a non-woven fabric. For example, the non-stretchable material may be a cotton material, or a high-density plain weave or twill weave using polyester or the like.

[0051] As described above, when the side fabric 40 is provided with an opening and closing member, it is possible to use the bedding 1 by replacing the mattress 20 housed inside the side fabric 40. Furthermore, inside the side fabric 40, the airbag 30 is located below the mattress 20. In this case, the airbag 30 inside the side fabric 40 can be inflated appropriately.

[0052] In this embodiment, "operation" means inflation by supplying air to the airbag 30 and deflation by exhausting air. The airbag 30 inflates and deflates in accordance with a sleep course (first course) and a good morning course (second course) organized by at least one operation mode, which is defined by the number of operations, which is the number of times the airbag 30 operates, and the operation time, which is the time for which the operation is performed. The "operation mode" indicates the content of a series of operations, the number of operations and the operation time, which are defined. "Organized by at least one operation mode" indicates that the airbag 30 is configured by one or more operation modes.

[0053] The sleep course will be described with reference to Fig. 5(a) and Fig. 5(b). Fig. 5(a) is a diagram showing a table of the sleep course. Fig. 5(b) is a diagram showing height adjustment of the airbag 30 in the sleep course. The unit in Fig. 5(b) is [seconds]. The sleep course is executed when a person falls asleep.

[0054] In FIG. 5(a), the "height adjustment," "back raising," "back lowering," "back adjustment," "left and right raising," and "one-step raising and then dropping" shown in the top row of the table each indicate the "operation modes" that make up the sleep course. In "height adjustment," the height of the airbag 30 is adjusted. In "back raising," the airbag 31 is inflated to raise the back. In "back lowering," the airbag 31 is deflated to lower the back. In "back adjustment," the amount of air in the airbag 31 is adjusted to adjust the height of the back.

[0055] In the "left and right lift" operation, the airbag 32 located below the right hip of the user (person) (hereinafter sometimes referred to as the right airbag 32) and the airbag 32 located below the left hip of the user (person) (hereinafter sometimes referred to as the left airbag 32) are alternately inflated, thereby lifting the right and left hips of the user alternately. In the "all-at-once lift->drop" operation, air is supplied to the airbag 31 to lift the user's back, and then the airbags 31, 32 are exhausted to lower the user's body.

[0056] "I" in the table of Fig. 5(a) indicates the supply of air (In) to the airbag 30, "K" in the table of Fig. 5(a) indicates a state in which the amount of air in the airbag 30 is maintained (Keep), and "O" in the table of Fig. 5(a) indicates the exhaust of air (Out) from the airbag 30. That is, at "I", the airbag 30 inflates, at "K", the amount of air in the airbag 30 is kept constant, and at "O", the airbag 30 deflates.

[0057] In the table of Fig. 5(a), "back" indicates the airbag 31 located below the user's back, "right hip" indicates the right airbag 32, and "left hip" indicates the left airbag 32. The "★" in Fig. 5(a) is related to the "★" in the table of Fig. 5(b), and indicates the time (in seconds) for adjusting the height of the airbag 31 when the person's body is soft ("soft" in Fig. 5(b)), when the person's body is hard ("hard" in Fig. 5(b)), and when the person's body is medium soft ("medium" in Fig. 5(b)).

[0058] In the sleep course, in the "height adjustment," when the reception unit 61 (see FIG. 8) described later receives that the person's body is soft, air is supplied for 20 seconds to make the airbag 31 harder; when the reception unit 61 receives that the person's body is hard, air is supplied for 12 seconds to make the airbag 31 softer; and when the reception unit 61 receives that the person's body is medium hardness, air is supplied for 17 seconds to make the airbag 31 medium hardness.

[0059] 5(a) indicates the operation time (in seconds) of the airbag 30. For example, in the "back lift" operation, air is supplied to the airbag 31 for 5 seconds, the amount of air in the airbag 31 is maintained (or the air is exhausted from the airbag 31) for 2 seconds, and then the airbag 31 is exhausted for 4 seconds.

[0060] The "☆" in Figure 5(a) relates to the "☆" in the table in Figure 5(b), and indicates the height (unit: [seconds]) of the airbag 31 for "quick lift → quick drop" when the person's body is soft, hard, and medium softness.

[0061] In the sleep course, at the beginning of the "quick rise → drop" process, when the reception unit 61 receives that the person's body is soft, air is supplied for 25 seconds to make the airbag 31 harder, when the reception unit 61 receives that the person's body is hard, air is supplied for 15 seconds to make the airbag 31 softer, and when the reception unit 61 receives that the person's body is medium soft, air is supplied for 20 seconds to make the airbag 31 medium hard.

[0062] In the sleep course, the number of times each of "back lifting," "back lowering," and "left and right lifting" is performed is, for example, 10. The number of times each of "height adjustment," "back adjustment," and "one-time lifting and then dropping" is performed is, for example, 1. The number of times each of these operation modes is performed is defined as the "number of operations." The numbers below "back lifting" and the like in the table of FIG. 5(a) indicate the "operation time." As mentioned above, the "operation time" is the time for which the airbag 30 is activated. The sleep course is organized by each of the above operation modes. The total operation time in the sleep course is, for example, approximately 10 minutes.

[0063] Depending on the hardness of the body of the person resting on the mattress 20, the inflation of the airbag 30 may place a strain on the body of the person, increasing discomfort or causing physical pain. Therefore, the height of the airbag 30 is adjusted according to the hardness of the body of the person resting on the mattress 20. The height of the airbag 30 can be adjusted to three levels: "soft," "medium," and "hard."

[0064] If the body of the person resting on the mattress 20 is soft, the setting is "soft." If the body of the person resting on the mattress 20 is hard, the setting is "hard." If the hardness of the body of the person resting on the mattress 20 is between "soft" and "hard," the setting is "medium." As a result, when a person with a soft body rests on the mattress 20, the height of the airbag 30 (in the height direction D3) is higher than when a person with a hard body rests on the mattress 20.

[0065] For example, in the bedding 1, before "height adjustment" is performed, it is possible to input whether the person's body is soft, whether the person's body is hard, or whether the softness of the person's body is medium. That is, the user can input "soft" if the body is soft, "hard" if the body is hard, and "medium" if the body is medium hard.

[0066] The height of the airbag 30 correlates with the hardness of the airbag 30. In other words, when the height of the airbag 30 is adjusted to "soft," the internal pressure of the supplied airbag 30 is high, so the airbag 30 becomes relatively hard. When the height of the airbag 30 is adjusted to "hard," the internal pressure of the supplied airbag 30 is low, so the airbag 30 becomes relatively soft. Therefore, the hardness of the airbag 30 is adjusted by adjusting the height of the airbag 30, and it is possible to adjust the hardness of the bedding 1 (mattress 20) via the airbag 30.

[0067] An example of the operation of supplying and discharging air to the airbag 30 in the sleep mode will be described in more detail. The sleep mode is executed from left to right in the table of FIG. 5(a). First, as described above, the receiving unit 61 receives whether the person's body is flexible, stiff, or medium stiffness. Then, the "height adjustment" described above is executed.

[0068] After the "height adjustment," "back lifting" is performed 10 times. In the "back lifting," air is supplied to the airbag 31 for 5 seconds, the amount of air in the airbag 31 is maintained (or the airbag 31 is exhausted) for 2 seconds, and then the airbag 31 is exhausted for 4 seconds. This cycle of supplying air, maintaining (or exhausting) the amount of air, and exhausting is performed 10 times.

[0069] After the "back raising," the "back lowering" is executed 10 times. In the "back lowering," the amount of air in the airbag 31 is maintained and air is supplied to each airbag 32 for 5 seconds, air is exhausted from the airbag 31 and the amount of air in each airbag 32 is maintained for 2 seconds, and then air is exhausted from each of the airbags 31 and 32 for 4 seconds.

[0070] After "back lowering," "back adjustment" is executed once. In "back adjustment," air is supplied to the airbag 31 and exhausted from each airbag 32 for eight seconds. After "back adjustment," "left and right raising" is executed ten times. In "left and right raising," air is supplied to and exhausted from the right airbag 32 and the left airbag 32 alternately. That is, when air is being supplied to the right airbag 32, exhaust from the left airbag 32 is performed, and when air is being exhausted from the right airbag 32, air is supplied to the left airbag 32. As a result, the left and right sides of the user's body are lifted alternately.

[0071] In "left and right raising," the amount of air in airbag 31 is maintained, air is supplied to the right airbag 32, and air is exhausted from the left airbag 32 for 10 seconds, the amount of air in airbag 31 and the right airbag 32 is maintained, and air is exhausted from the left airbag 32 for 2 seconds, the amount of air in airbag 31 is maintained, air is supplied to the left airbag 32, and air is exhausted from the right airbag 32 for 10 seconds, and the amount of air in airbag 31 and the left airbag 32 is maintained, and air is exhausted from the right airbag 32 for 2 seconds.

[0072] After the "left and right lift" sequence, a "quick lift → drop" sequence is executed once. In the "quick lift → drop" sequence, the amount of air in each airbag 32 is maintained, and air is supplied to the airbag 31 according to the flexibility of the body. Air is supplied to the airbag 31 for the number of seconds indicated by the "☆" in the table shown in FIG. 5(b). That is, air is supplied to the airbag 31 for 25 seconds when the body is soft ("soft"), for 15 seconds when the body is hard ("hard"), and for 20 seconds when the body is medium hardness ("medium"). The longer the time for which air is supplied to the airbag 31, the harder the airbag 31 becomes, and the shorter the time for which air is supplied to the airbag 31, the softer the airbag 31 becomes. In this embodiment, when the body is soft, the time for which air is supplied to the airbag 31 is longer than when the body is hard, thereby making the airbag 31 harder.

[0073] The air volume in each of the airbags 31 and 32 is maintained for 10 seconds, and air is exhausted from each of the airbags 31 and 32 for 40 seconds. After that, the series of steps in the sleep course is completed. The sleep course mainly moves the back area, which has a large amount of muscle mass, which relieves tension in the body compared to falling asleep without the sleep course, and induces smoother falling asleep.

[0074] Next, the Good Morning course will be described with reference to Figures 6(a) and 6(b). Figure 6(a) is a diagram showing a table of the Good Morning course. Figure 6(b) is a diagram showing height adjustment of the airbag 30 in the Good Morning course. The unit in Figure 6(b) is [seconds]. The Good Morning course is executed when a person wakes up.

[0075] Like the Good Morning Course, the Good Morning Course is organized into multiple operation modes. Some of the "operation modes" of the Good Morning Course are the same as some of the "operation modes" of the Good Morning Course. Therefore, in the following, explanations that overlap with the explanation of the Good Morning Course will be omitted as appropriate. For example, the Good Morning Course has more types of operation modes than the Good Morning Course.

[0076] The table in FIG. 6(a) can be read in the same way as the table in FIG. 5(a). For example, FIG. 6(b) is the same as FIG. 5(b). The "operation modes" that make up the "Good Morning Course" are, for example, "cradle," "back lift," "simultaneous left and right lift," "back up and down," "back down," and "drop." In "cradle," similar to the aforementioned "left and right lift," the right airbag 32 and the left airbag 32 are alternately inflated to alternately lift the user's right and left hips. In "simultaneous left and right lift," the right airbag 32 and the left airbag 32 are simultaneously inflated to simultaneously lift the user's right and left hips. In "back up and down," the airbag 31 is inflated to lift the user's back, and then the airbag 31 is deflated to lower the user's back. In "drop," the airbags 31 and 32 are each deflated to lower the user's body.

[0077] An example of the operation of supplying and exhausting air to the airbag 30 in the Good Morning course will be described in more detail. The Good Morning course is executed from left to right in the table of FIG. 6(a). First, the "height adjustment" is executed, as in the above-mentioned Good Morning course. In the "height adjustment" of the Good Morning course, air is supplied to the airbag 31 for the number of seconds indicated by the "★" in the table shown in FIG. 6(b). That is, air is supplied to the airbag 31 for 20 seconds when the body is soft ("soft"), for 12 seconds when the body is hard ("hard"), and for 17 seconds when the body is medium hardness ("medium").

[0078] After the "height adjustment," the "cradle" and the "back lift" are alternately performed. In this embodiment, the first "cradle," the first "back lift," the second "cradle," the second "back lift," the third "cradle," the third "back lift," the fourth "cradle," and the fourth "back lift" are performed in this order.

[0079] The first "cradle" is executed twice. In the first "cradle," the air volume in the airbag 31 is maintained, air is supplied to the right airbag 32, and air is exhausted from the left airbag 32 for 10 seconds, the air volume in the airbag 31 and the right airbag 32 is maintained, and air is exhausted from the left airbag 32 for 1 second, the air volume in the airbag 31 is maintained, air is exhausted from the right airbag 32, and air is supplied to the left airbag 32 for 10 seconds, and the air volume in the airbag 31 and the left airbag 32 is maintained, and air is exhausted from the right airbag 32 for 1 second.

[0080] The first "back lift" is executed once. In the "back lift," the air volume in the airbag 31 and the left airbag 32 is maintained and air is supplied to the right airbag 32 for five seconds, and air is supplied to the airbag 31 and the air volume in each airbag 32 is maintained for seven seconds.

[0081] The second "cradle" is the same as the first "cradle" except that "maintaining the amount of air in the airbag 31 and the right airbag 32, and exhausting the air from the left airbag 32 (for 1 second)" in the first "cradle" is changed to "exhausting the air from the airbag 31 and the left airbag 32, and maintaining the amount of air in the right airbag 32 (for 1 second)." The second "cradle" is executed twice.

[0082] The second "back lift" is the same as the first "back lift" except that air is supplied to the airbags 31 and the air volume in each airbag 32 is maintained for 25 seconds instead of 7 seconds. The second "back lift" is performed once.

[0083] The third "cradle" is identical to the first "cradle" except that the air volume in the airbag 31 is maintained, air is supplied to the right airbag 32, and air is exhausted from the left airbag 32 for seven seconds, and the air volume in the airbag 31 is maintained, air is exhausted from the right airbag 32, and air is supplied to the left airbag 32 for seven seconds.

[0084] The third "back lift" is the same as the first "back lift" except that air is supplied to the airbags 31 and the amount of air in each airbag 32 is maintained for 15 seconds.

[0085] In the fourth "cradle" test, the air volume in airbag 31 is maintained, air is supplied to right airbag 32, and air is exhausted from left airbag 32 for 7 seconds, air is exhausted from airbag 31 and left airbag 32, and air is supplied to right airbag 32 for 1 second, the air volume in airbag 31 is maintained, air is exhausted from right airbag 32, and air is supplied to left airbag 32 for 7 seconds, air is exhausted from airbag 31 and right airbag 32, and air is supplied to left airbag 32 for 1 second.

[0086] The fourth "back lift" is the same as the third "back lift". After the fourth "back lift", "left and right simultaneous lift" is executed four times. In the "left and right simultaneous lift", air is exhausted from the airbag 31 and supplied to each airbag 32 for four seconds, and air is exhausted from the airbag 31 and the amount of air in each airbag 32 is maintained for two seconds.

[0087] After "Lift left and right simultaneously," "Back up and down" is executed once. In "Back up and down," air is supplied to the airbag 31 and the amount of air in each airbag 32 is maintained for 15 seconds, and air is exhausted from the airbag 31 and each airbag 32 for 4 seconds.

[0088] After the "back up and down" command, the "back up" command is executed five times. In the "back up" command, air is supplied to the airbag 31 and exhausted from each airbag 32 for 15 seconds, and the amount of air in the airbag 31 is maintained and exhausted from each airbag 32 for 5 seconds.

[0089] After "back raising," "back lowering" is executed once. In "back lowering," air is exhausted from the airbag 31 and each airbag 32 for 7 seconds, the amount of air in the airbag 31 is maintained, and air is exhausted from each airbag 32 for 5 seconds.

[0090] After the "back lowering," the "cradle" is executed four times. In the "cradle," the airbag 31 and the left airbag 32 are vented and air is supplied to the right airbag 32 for three seconds, the airbag 31 is vented, the air volume in the right airbag 32 is maintained, and air is supplied to the left airbag 32 for three seconds, the airbag 31 is vented, the right airbag 32 is supplied, and the air volume in the left airbag 32 is maintained for three seconds, and the airbag 31 is vented, the right airbag 32 is supplied, and the air volume in the left airbag 32 is maintained for three seconds.

[0091] After "cradle," "back up and down" is executed once. In "back up and down," air is supplied to the airbags 31 according to the body's flexibility while the amount of air in each airbag 32 is maintained. Air is supplied to the airbags 31 for the number of seconds indicated by the "☆" in the table shown in FIG. 6(b). This air supply adjusts the height of the airbags 31 for 25 seconds when the body is flexible ("soft"), 15 seconds when the body is stiff ("hard"), and 20 seconds when the body's stiffness is medium ("medium"). Thereafter, air is exhausted from the airbags 31 and each airbag 32 for 10 seconds.

[0092] After the "back up and down" command, the "back up" command is executed five times. In the "back up" command, air is supplied to the airbag 31 and exhausted from each airbag 32 for five seconds, and the amount of air in the airbag 31 is maintained and exhausted from each airbag 32 for two seconds.

[0093] After the "back lift" step, a "drop" step is performed once. In the "drop" step, the airbag 31 and each airbag 32 are vented for 20 seconds. After that, the series of steps in the good morning course is completed. The total operation time in the good morning course is, for example, the same as the operation time in the good night course, which is about 10 minutes. In the good morning course, the heat metabolism is increased by gradually moving the muscles when waking up, and the body temperature is raised, promoting waking.

[0094] The number of operation modes executed per unit time in the sleep course is less than the number of operation modes executed per unit time in the good morning course. Therefore, the sleep course executed when falling asleep generates slow movements, thereby providing a stimulus that promotes relaxation in the person and activating the person's parasympathetic nervous system. On the other hand, the good morning course executed when waking up generates active movements, thereby providing a stimulus to the person.

[0095] 7(a) and 7(b) are diagrams showing a stretching course. The stretching course is, for example, a course (third course) positioned between the good night course and the good morning course. The stretching course is executed, for example, when one wants to stretch the whole body evenly.

[0096] The number of operation modes executed per unit time in the stretch course is greater than the number of operation modes executed per unit time in the sleep course and is less than the number of operation modes executed per unit time in the good morning course. The stretch course can be executed at any timing, for example. The stretch course may be executed after the good morning course or before the sleep course, for example.

[0097] The table in FIG. 7(a) can be read in the same way as the table in FIG. 5(a), and the table in FIG. 7(b) can be read in the same way as the table in FIG. 5(b). The stretching course also has operation modes, similar to the good morning course and the good night course. The operation modes in the stretching course are the segments shown in the top row of FIG. 7(a), such as "raise your back and stretch your shoulder blades," "twist your hips side by side," "raise your hips side by side and arch your back," "lift your whole body," and "rhythmically lift your hips." "raise your back and stretch your shoulder blades," "rhythmically lift your hips," "twist your hips side by side," and "raise your hips side by side and arch your back" are performed, for example, twice. "Lift your whole body" is performed, for example, four times. The stretching course is organized according to the operation modes described above.

[0098] The table in Fig. 7(a) shows the operation of the airbag 30 when a person's body is placed on the surface 21 of the mattress 20. The bottom three rows of the table in Fig. 7(a) show, from top to bottom, the operation of the airbag 30 for the back, right hip, and left hip. The back, right hip, and left hip correspond to airbag 31, right airbag 32, and left airbag 32, respectively. The total operation time for the stretching course is the same as the total operation time for the sleep course and the good morning course, for example, and is approximately 10 minutes.

[0099] For example, the first stretching course, "raise your back and stretch your shoulder blades," is executed once. In "raise your back and stretch your shoulder blades," air is supplied to the airbag 31 for 20 seconds, exhausted from the airbag 31 for 5 seconds, and the amount of air in the airbag 31 is maintained for 5 seconds. None of the airbags 32 are activated.

[0100] Each operation mode in the stretching course involves large body movements, such as arching the back or twisting the waist. The body movements in the stretching course are greater than those in the sleep course and the good morning course. Therefore, the stretching course is performed when you want to stretch your entire body evenly.

[0101] FIG. 7(b) is a diagram showing the height adjustment of the airbag 30 in the stretch course. In the stretch course, "height adjustment" is performed, as in the sleep course and good morning course. In "height adjustment," the height of the airbag 30 is adjusted according to the hardness of the body of the person placed on the mattress 20. For example, if a person with a flexible body is placed on the mattress 20, air is supplied to the airbag 30 for 15 seconds immediately before the "high back lift and shoulder blade stretch" step so that the hardness of the airbag 30 in the height direction D3 becomes hard. Similarly, in the final "full lift" step, for example, air is supplied to the airbag 30 for 15 seconds so that the hardness of the airbag 30 in the height direction D3 becomes hard.

[0102] 8 is a schematic diagram showing the control unit 60 and the air control device 50. The bedding 1 includes the air control device 50 and the control unit 60. The air control device 50 supplies and exhausts air to and from each of the airbags 30. The air control device 50 is, for example, an air pump.

[0103] 1 and 2, the air control device 50 will be described. The air control device 50 is connected to the airbag 30 and has an air hose 51 that supplies air to the airbag 30. The air hose 51 is arranged at both ends of the mattress 20 in the width direction D2, which is a direction intersecting the height direction D3. The air hose 51 extends along the longitudinal direction D1 on each of both ends in the width direction D2 as seen from the airbag 30. In a plan view (when viewed along the height direction D3), the air hose 51 is not arranged in the center of the bedding 1, but extends along the outer periphery of the bedding 1 (e.g., the mattress 20). This prevents the body of a user lying on the bedding 1 from being positioned above the air hose 51, thereby reducing discomfort felt by the user.

[0104] 2 and 3, the air control device 50 has a plurality of air hoses 51 (four, for example). One end of each air hose 51 is connected to the airbag 31 and the airbag 32, respectively. Specifically, at the connection points between the air hoses 51 and the airbag 30, the plurality of air hoses 51 are lined up along the width direction D2. Of the plurality of air hoses 51, two air hoses 51 located on the inner side in the width direction D2 are connected to the airbag 31. Of the plurality of air hoses 51, two air hoses 51 located on the outer side in the width direction D2 are connected to the portion 322 of the airbag 32.

[0105] The air control device 50 has an air hose group 53, which is a bundle of multiple air hoses 51. The air hose group 53 extends, for example, from the main body of the air control device 50 (the rectangular parallelepiped part in FIGS. 1 and 2) toward the airbag 30.

[0106] The air control device 50 has an adapter 52. In the adapter 52, multiple air hoses 51 branch off from an air hose group 53. The adapter 52 has one end face and the other end face facing opposite each other in the longitudinal direction D1. Each of the branched air hoses 51 extends from one end face of the adapter 52, and the air hose group 53 extends from the other end face of the adapter 52.

[0107] As described above, the multiple air hoses 51 constituting the air hose group 53 branch off at the adapter 52. Some of the multiple air hoses 51 extend from the adapter 52 to one side in the width direction D2, and the remaining portions of the multiple air hoses 51 extend from the adapter 52 to the other side in the width direction D2. The air hoses 51 extending from the adapter 52 to the end sides in the width direction D2 are bent in the longitudinal direction D1 at corners (e.g., four corners) of the floor covering 35. The air hoses 51 bent in the longitudinal direction D1 extend along the longitudinal direction D1 at the end parts of the floor covering 35 in the width direction D2 and are folded back towards the airbag 30. Each of the multiple air hoses 51 folded back towards the airbag 30 is connected to the airbag 30.

[0108] The adapter 52 is fixed to the end of the rug 35 on the opposite side to the headboard 2a in the longitudinal direction D1. The adapter 52 is fixed to the side fabric 40 with a portion of the adapter 52 exposed from the side fabric 40. The adapter 52 is placed at the feet of a person resting on the mattress 20. Therefore, the air hose group 53 is configured to extend from the person's feet to the outside of the mattress 20. This makes it possible to prevent the air hose 51 (air hose group 53) from coming into contact with the person's body.

[0109] The air hose 51 is fixed onto the rug 35. The air hose 51 is fixed to the rug 35 by, for example, a tape-shaped member. The tape-shaped member covers a portion of the air hose 51 and is fixed to the rug 35 while extending in a direction intersecting the air hose 51. For example, both ends of the tape-shaped member are fixed to the rug 35 by sewing. As an example, the tape-shaped member is made of a fabric made of a non-stretchable material. The length of the tape-shaped member in a direction intersecting the air hose 51 is longer than the width (thickness) of the air hose 51. The length of the tape-shaped member in a direction along the air hose 51 is shorter than the length of the tape-shaped member in the direction intersecting the air hose 51. The bedding 1 has multiple tape-shaped members, which are arranged in a line along the air hose 51. In this case, the air hose 51 can be fixed to the rug 35 at multiple points by the multiple tape-shaped members. As a result, the position of the air hose 51 can be stabilized even when a person lying on the mattress 20 turns over in their sleep. The air hose 51 is housed in the side fabric 40.

[0110] The control unit 60 will be described again with reference to Fig. 8. The control unit 60 is mounted on, for example, a terminal 65. The control unit 60 is, for example, software (application) installed on the terminal 65. In this embodiment, the "terminal" includes a mobile terminal such as a tablet or a smartphone, and a computer such as a personal computer or a laptop computer.

[0111] The control unit 60 controls the air supply and exhaust of the air control device 50. As a result, the air bag 30 is inflated and deflated by the air control device 50. Therefore, the control unit 60 can cause the air bag 30 to perform a desired operation, and a good night's sleep course, a good morning course, or a stretch course is executed.

[0112] The terminal 65 is, for example, a computer (which may be a server). The terminal 65 includes, for example, a processor (for example, a CPU) that executes an operating system and an application program, a main memory unit configured with ROM or RAM, an auxiliary memory unit configured with a hard disk or flash memory, and a communication control unit configured with a network card or a wireless communication module.

[0113] Each functional element of the terminal 65 is realized by loading software into the processor or main memory and executing the software. The processor operates the communication control unit in accordance with the software and reads or writes data from or to the main memory or auxiliary memory. Data required for computer processing is stored in the main memory or auxiliary memory.

[0114] The control unit 60 includes, as functional elements, a reception unit 61 and an execution unit 62. The reception unit 61 receives execution information, which is information indicating whether or not to execute the good night course and the good morning course. The reception unit 61 also receives execution information, which is information indicating whether or not to execute the stretch course. By the reception unit 61 receiving the execution information, the good night course, the good morning course, and the stretch course can be selected and started.

[0115] The reception unit 61 displays a screen on the display of the terminal 65 that allows the user to select, for example, at least one of a good night course, a good morning course, and a stretching course. As an example, buttons indicating the good night course, the good morning course, and the stretching course are displayed on the display of the terminal 65. In this case, the user (person) can select at least one of the good night course, the good morning course, and the stretching course by tapping the display. The user may select at least one of the good night course, the good morning course, and the stretching course by operating a mouse provided on the terminal 65.

[0116] The reception unit 61 receives at least one of the selected sleep course, good morning course, and stretch course. This determines which course will be executed by the air control device 50 and the airbag 30. For example, the reception unit 61 may receive the time at which the sleep course, good morning course, and stretch course will be executed. In this case, the sleep course, good morning course, and stretch course can be executed at that time. The reception unit 61 may be password-locked. In this case, unintended operation of the terminal 65 by others can be prevented.

[0117] The reception unit 61 includes, for example, a communication unit constituting a network module, and may include a wireless communication interface such as wireless LAN or Bluetooth (registered trademark). The reception unit 61 may be able to communicate with the control unit 60 via the communication unit described above. As a result, the reception unit 61 may function as a remote control.

[0118] The receiving unit 61 receives either that the person's body is flexible or that the person's body is hard. The receiving unit 61 may also receive that the person's body flexibility (hardness) is medium. When the receiving unit 61 receives that the person's body is flexible, the control unit 60 controls the air control device 50 to increase the amount of air supplied to the airbag 30 compared to when the receiving unit 61 received that the person's body is hard. When the receiving unit 61 receives that the person's body flexibility is medium, the control unit 60 may control the air control device 50 to increase the amount of air supplied to the airbag 30 compared to when the receiving unit 61 received that the person's body is hard, or may control the air control device 50 to decrease the amount of air supplied to the airbag 30 compared to when the receiving unit 61 received that the person's body is flexible. This achieves the height adjustment of the airbag 30 in FIGS. 5(b), 6(b), and 7(b).

[0119] The execution unit 62 causes the air control device 50 to execute at least one of a good night's sleep course and a good morning course in accordance with the execution information received by the reception unit 61. The execution unit 62 also causes the air control device 50 to execute a stretching course in accordance with the execution information received by the reception unit 61.

[0120] The execution unit 62 may be capable of communicating with the air control device 50 via, for example, a wired cable. The execution unit 62 may also include, for example, a communication unit constituting a network module, or may include a wireless communication interface such as wireless LAN or Bluetooth (registered trademark). The execution unit 62 may be capable of communicating with the air control device 50 via the communication unit described above.

[0121] The good morning course may be set before going to bed. The execution unit 62 is, for example, a program that executes a good night course that was set before a person went to bed when the person falls asleep. In this case, the reception unit 61 receives which course to execute (execution information) by operating the terminal 65 before the person goes to bed, and the execution unit 62 executes the good night course (or stretching course) included in the execution information received by the reception unit 61 when the person falls asleep.

[0122] The execution unit 62 may be a program that executes a good morning course set before a person goes to bed when the person wakes up. In this case, the reception unit 61 receives execution information by operating the terminal 65 before the person goes to bed, and the execution unit 62 executes the good morning course (or stretching course) included in the execution information received by the reception unit 61 when the person wakes up.

[0123] The execution unit 62 may be a program that executes the good morning course (or stretching course) when, for example, a person wakes up by operating the terminal 65. Furthermore, the execution unit 62 may be a program that executes the good morning course when an alarm (an alarm that prompts a person to wake up) that the person set before going to bed goes off.

[0124] Next, the effects obtained from the bedding 1 according to this embodiment will be described in more detail. In this bedding 1, an airbag 30 is attached to the mattress 20. An air control device 50 is connected to the airbag 30, and the airbag 30 performs operations such as inflation by supplying air and deflation by exhausting air. The air control device 50 controls the supply and exhaust of air to the airbag 30 by a control unit 60. An operation mode is defined by the number of operations, which is the number of times the airbag 30 operates, and the operation time, which is the time for which the operation is performed. The airbag 30 provided in this bedding 1 operates according to an operation mode in which the number of operations and operation time are defined, so that the accuracy of inflation and deflation of the airbag 30 can be increased.

[0125] The operation modes are then organized into a good night course and a good morning course. The good night course is executed when a person falls asleep, and the good morning course is executed when a person wakes up. The number of operation modes executed per unit time in the good night course is fewer than the number of operation modes executed per unit time in the good morning course. As a result, the good night course executed when falling asleep provides stimulation that promotes relaxation through slow movements, activating the person's parasympathetic nervous system and guiding the person to sleep smoothly. On the other hand, the good morning course executed when waking up provides stimulation through active movements, activating the person's sympathetic nervous system. This can help the person start activities immediately when they wake up, thereby promoting their awakening. Therefore, this bedding 1 can promote more comfortable falling asleep and waking up.

[0126] In this embodiment, when a person's body is flexible, the amount of air supplied to the airbag 30 can be increased to raise the airbag 30, and when a person's body is stiff, the amount of air supplied to the airbag 30 can be reduced to lower the height of the airbag 30. By lowering the height of the airbag 30 when the person's body is stiff, the pain and discomfort felt by the person due to stretching can be reduced. By raising the airbag 30 when the person's body is flexible, the stretching effect can be enhanced for people with flexible bodies. Therefore, it is possible to promote more comfortable falling asleep and waking up.

[0127] Furthermore, because the upper portion 41 of the side fabric 40, which is the portion that contacts the mattress 20, is made of an elastic material, the mattress 20 can easily flexibly follow the movements of the person's body. This allows the mattress 20 to flexibly deform according to the shape of the person's body. This reduces discomfort felt by the person, promoting more comfortable sleep and awakening. Because the air hose 51 is fixed to the lower portion 42 of the side fabric 40, which is made of a non-elastic material, the position of the air hose 51 can be stabilized even when the person turns over in sleep. This allows for a stable supply of air to the airbag 30.

[0128] Furthermore, since the air hoses 51 are arranged at both ends of the mattress 20 in the width direction D2, it is possible to reduce the possibility that the body of a person placed on the surface 21 of the mattress 20 will come into contact with the air hoses 51. This reduces the discomfort felt by the person, thereby promoting more comfortable falling asleep and waking up.

[0129] Furthermore, if the thickness of the mattress 20 is 3 cm or more, slits can be easily formed in the mattress 20. If the thickness of the mattress 20 is 15 cm or less, the thickness of the mattress 20 can be prevented from becoming too thick.

[0130] (Second embodiment) Next, a bedding 1A according to a second embodiment will be described. As shown in Figs. 9 and 10, the bedding 1A has a mattress 20A that is different from the mattress 20 described above. The mattress 20A has slits 22a1 and 22a2 (first slits) formed on a back surface 22A. The back surface 22A is a surface that faces vertically downward. The back surface 22A faces the opposite side to the body of a person who will be resting on the mattress 20A. The mattress 20A has slits 21a1 and 21a2 (second slits) formed on a front surface 21A. In these respects, the mattress 20A of the bedding 1A differs from that of the first embodiment. However, some of the configuration of the bedding 1A is the same as some of the configuration of the bedding 1 described above. Therefore, in the following, explanations that overlap with the first embodiment will be omitted as appropriate.

[0131] The mattress 20A has a front surface 21A facing vertically upward and a back surface 22A facing in the opposite direction to the front surface 21A. FIG. 9 is a bottom view showing the back surface 22A of the mattress 20A according to the second embodiment. A plurality of slits 22a1, 22a2 are formed on the back surface 22A. The slit 22a1 extends along the width direction D2. The slit 22a2 extends along the longitudinal direction D1.

[0132] The slits 22a2 are formed in an area including the center of the mattress 20A in the width direction D2. The slits 22a2 are not formed at either end of the mattress 20A in the width direction D2. The slits 22a1 are formed in the center of the mattress 20A in the longitudinal direction D1 and at positions closer to the ends of the mattress 20A in the longitudinal direction D1. For example, the multiple slits 22a1 are formed in a portion of the mattress 20A closer to the headboard 2a than the center of the mattress 20A in the longitudinal direction D1.

[0133] The underside 22A of the mattress 20A has a chest region 25 and a lumbar region 26. The chest region 25 is a portion that is aligned with the chest of a person lying on their back on the bedding 1 in the height direction D3. The lumbar region 26 is a portion that is aligned with the waist of a person lying on their back on the bedding 1 in the height direction D3. Both the chest region 25 and the lumbar region 26 are formed with both a slit 22a1 and a slit 22a2. The chest region 25 and the lumbar region 26 are regions where the slits 22a1 and 22a2 intersect. The lumbar region 26 and the chest region 25 are aligned with each other in the longitudinal direction D1. The lumbar region 26 is located between the chest region 25 and the adapter 52.

[0134] For example, the area of ​​the chest region 25 is larger than the area of ​​the lumbar region 26. The chest region 25 and the lumbar region 26 are, for example, rectangular. For example, the length of the chest region 25 in the width direction D2 is longer than the length of the chest region 25 in the longitudinal direction D1, and the length of the lumbar region 26 in the width direction D2 is longer than the length of the lumbar region 26 in the longitudinal direction D1. However, the area, shape, and length of each part of the chest region 25 and the lumbar region 26 are not limited to the above example and can be changed as appropriate.

[0135] The mattress 20A has, for example, a non-slit region where no slits are formed, a single-slit region where either the slit 22a1 or the slit 22a2 is formed, and a multi-slit region where both the slit 22a1 and the slit 22a2 are formed. The multi-slit regions are the chest region 25 and the lumbar region 26 described above. The single-slit regions are formed between two multi-slit regions aligned along the longitudinal direction D1, on both sides of the multi-slit region in the longitudinal direction D1 of the mattress 20A, and on both sides of the multi-slit region in the width direction D2 of the mattress 20A. The non-slit regions are formed at the four corners of the mattress 20A in a plan view and between two single-slit regions aligned along the longitudinal direction D1. The single-slit region is more easily deformed than the non-slit region, and the multi-slit region is more easily deformed than the single-slit region. By having the single-slit region and the multi-slit region, the mattress 20A can be locally deformed in each region.

[0136] The end of the chest region 25 on the headboard 2a side is located at a distance L2 from the end of the mattress 20A on the headboard 2a side. The distance L2 is, for example, 15 cm or more and 35 cm or less. The length L3 of the chest region 25 in the longitudinal direction D1 is, for example, 40 cm or more and 60 cm or less. The length L1 of the chest region 25 in the width direction D2 is, for example, 50 cm or more and 70 cm or less. The length of the lumbar region 26 in the width direction D2 is, for example, 50 cm or more and 70 cm or less, similar to the length L1.

[0137] In the longitudinal direction D1, the chest region 25 and the waist region 26 are spaced apart from each other by a distance L4. The distance L4 is, for example, 1 cm or more and 10 cm or less. The length L5 of the waist region 26 in the longitudinal direction D1 is, for example, 25 cm or more and 45 cm or less.

[0138] The depths (lengths in the height direction D3) of the slits 22a1 and 22a2 are, for example, the same throughout both the longitudinal direction D1 and the width direction D2. The arrangement interval d11 (pitch) of the slits 22a1 in the longitudinal direction D1 is uniform. The arrangement interval d12 of the slits 22a2 in the width direction D2 is uniform. The arrangement intervals d11 and d12 are, for example, the same length. The arrangement intervals d11 and d12 are, for example, 1 cm or more and 5 cm or less.

[0139] 10 is a plan view showing the surface 21A of a mattress 20A according to the second embodiment. A plurality of slits 21a1 and 21a2 are formed on the surface 21A. The slit 21a1 extends along the width direction D2. The slit 21a2 extends along the longitudinal direction D1.

[0140] The slits 21a1 and 21a2 are formed, for example, over the entire surface 21A. The depths of the slits 21a1 and 21a2 in the height direction D3 are, for example, the same over the entire surface 21A in both the longitudinal direction D1 and the width direction D2. The arrangement interval d21 of the slits 21a1 in the longitudinal direction D1 is, for example, uniform. The arrangement interval d22 of the slits 21a2 in the width direction D2 is, for example, uniform. The arrangement intervals d21 and d22 are, for example, the same length. The arrangement intervals d21 and d22 are, for example, 1 cm or more and 5 cm or less.

[0141] As described above, the arrangement intervals d21 and d22 are, for example, the same length. However, the arrangement intervals d21 and d22 are not limited to the above. For example, the length of the arrangement interval d21 may be longer than the length of the arrangement interval d22. Furthermore, for example, the length of the arrangement interval d21 may be shorter than the length of the arrangement interval d22. In this case, the shape of the rectangular region of the mattress 20A defined by a pair of slits 21a1 adjacent to each other along the longitudinal direction D1 and a pair of slits 21a2 adjacent to each other along the width direction D2 becomes rectangular.

[0142] 9 and 10, mattress 20A has a first rectangular region defined by a pair of slits 21a1 aligned along longitudinal direction D1 and a pair of slits 21a2 aligned along width direction D2, and a second rectangular region defined by a pair of slits 22a1 aligned along longitudinal direction D1 and a pair of slits 22a2 aligned along width direction D2. The first rectangular region is formed on front surface 21A, and the second rectangular region is formed on back surface 22A. For example, the area of ​​the first rectangular region is larger than the area of ​​the second rectangular region.

[0143] The first rectangular region and the second rectangular region are surrounded by slits, and therefore can deform independently of each other. By including the first rectangular region and the second rectangular region in the mattress 20A, each of the first rectangular region and the second rectangular region can be locally deformed.

[0144] Fig. 11 is a diagram showing a portion of a cross section taken along line XI-XI in Fig. 9. The cross section in Fig. 11 shows a cross section perpendicular to the longitudinal direction D1. As shown in Figs. 9 to 11, the arrangement interval d22 of the slits 21a2 provided on the front surface 21A is wider than the arrangement interval d12 of the slits 22a2 provided on the back surface 22A. For example, the depth of the slits 21a2 is shallower than the depth of the slits 22a2.

[0145] For example, as the airbag 30 described above inflates, spaces V1 and V2 are formed on the back surface 22A of the mattress 20A. More specifically, when the airbag 30 inflates, the portion between the pair of slits 22a2 is locally recessed, thereby forming spaces V1 and V2 of different depths. In this way, by providing the slits 22a2 on the back surface 22A of the mattress 20A, the mattress 20A becomes more easily movable locally.

[0146] When the airbag 30 inflates, as described above, the spaces V1 and V2 are formed on the back surface 22A, and the front surface 21A bulges in the height direction D3. At this time, the front surface 21A bulges locally compared to when there are no slits 21a2. More specifically, when the airbag 30 inflates, the front surface 21A bulges and the multiple slits 21a2 located directly above the inflated airbag 30 widen, causing the portions between the multiple slits 21a2 to bulge locally.

[0147] As described above, the mattress 20A has the slits 21a2 formed in the front surface 21A and the slits 22a2 formed in the back surface 22A. This allows the mattress 20A to easily follow the inflation of the airbag 30. Therefore, the mattress 20A can surround the inflated airbag 30. In addition, the slits 22a2 allow the heights of the spaces V1 and V2 (lengths in the height direction D3) to be different from each other. This allows the height of the mattress 20A to be adjusted.

[0148] At least a portion of the air hose 51 described above may be provided in the slits 22a1 and 22a2 of the back surface 22A. The air hose 51 can be housed in the slits 22a1 and 22a2. The width (thickness) of the air hose 51 is set to a width that allows it to be inserted into the slits 22a1 and 22a2. For example, the air hose 51 is housed inside the slits 22a1 and 22a2 in a state in which the slits 22a1 and 22a2 are expanded.

[0149] When at least a portion of the air hose 51 is inserted into the slits 22a1, 22a2, the area of ​​the air hose 51 exposed on the back surface 22A can be reduced. That is, the amount of the air hose 51 exposed on the back surface 22A of the mattress 20A can be reduced. In this case, the bulging of the mattress 20A in the height direction D3 due to the air hose 51 being exposed on the back surface 22A can be reduced. Therefore, deformation of the mattress 20A due to the air hose 51 being exposed on the back surface 22A can be prevented, making it less likely that a person will feel uncomfortable.

[0150] 12(a) is an enlarged side view showing slit 21a2 or slit 22a2 of mattress 20A according to the second embodiment. The tip portions of slit 21a2 and slit 22a2 have a circular cross section. The portions of slit 21a2 and slit 22a2 other than the tip portions are linear.

[0151] FIG. 12(b) is an enlarged side view showing slit 21b2 or slit 22b2 of a mattress 20B according to a modified example. Slit 21b2 is a slit provided on the front surface 21B of the mattress 20B. Slit 22b2 is a slit provided on the back surface 22B of the mattress 20B. Slit 21b2 extends along the longitudinal direction D1. Slit 22b2 extends along the longitudinal direction D1. The tip portions of slit 21b2 and slit 22b2 do not have a circular cross section. Slit 21b2 and slit 22b2 are U-shaped.

[0152] The length (width) of the slits 21a2, 22a2 and slits 21b2, 22b2 in the width direction D2 is, for example, 1 mm or more and 10 mm or less. The depth of the slits 21a2, 22a2 and slits 21b2, 22b2 is, for example, 1 cm or more and 5 cm or less. If these slits were not present, the mattress would rise overall in the height direction D3 when the airbag 30 inflates. When a person sits on the mattress, the weight of the person acts on the mattress. At this time, the mattress is compressed in the height direction D3, making the mattress hard. However, if the mattress has slits as described above, the way the mattress sinks can be changed by changing the arrangement and shape of the slits, allowing the hardness of the mattress to be adjusted.

[0153] By providing the slits as described above, it is possible to locally adjust the hardness of the mattresses 20A, 20B when the airbag 30 is inflated. For example, when the airbag 30 is inflated, it is possible to make the mattresses 20A, 20B harder by targeting the areas of the mattresses 20A, 20B that are likely to bear weight, such as the lower back of a person lying on the mattresses 20A, 20B.

[0154] As described above, in the mattress 20A of the bedding 1A according to the second embodiment, the slits 22a1, 22a2 are provided on the back surface 22A opposite to the front surface 21A on which the person's body rests, thereby enabling the mattress 20A to deform locally. This allows the mattress 20A to deform locally and flexibly, making it easier for the deformation of the mattress 20A to follow the inflation of the airbag 30. For example, the mattress 20A can be set in a state in which it surrounds the inflated airbag 30. This more reliably reduces discomfort felt by a person resting on the mattress 20A, facilitating more comfortable sleep and awakening.

[0155] Furthermore, by providing at least a portion of the air hose 51 within the slits 22a1, 22a2, the amount of the air hose 51 exposed on the back surface 22A of the mattress 20A can be reduced. This prevents the mattress 20A from being deformed by the air hose 51 exposed on the back surface 22A, making it less likely that the person will feel uncomfortable and promoting more comfortable falling asleep and waking up.

[0156] Furthermore, by providing slits 21a1 and 21a2 in the surface 21A of the mattress 20A on which the person's body rests, the mattress 20A can be locally deformed. This allows the mattress 20A to flexibly deform locally, making it easier for the deformation of the mattress 20A to follow the inflation of the airbag 30. For example, the mattress 20A can be set in a state in which it surrounds the inflated airbag 30. This more reliably reduces discomfort felt by a person resting on the mattress 20A, and promotes more comfortable falling asleep and waking up.

[0157] (Third embodiment) Next, bedding 1C according to a third embodiment will be described with reference to Fig. 13(a) and Fig. 13(b). Fig. 13(a) is a partial side view showing a mattress 20C according to a third embodiment as seen from the width direction D2. Fig. 13(b) is a partial side view showing a mattress 20C according to a third embodiment as seen from the longitudinal direction D1. The mattress 20C has a front surface 21C and a back surface 22C. Slits 21b1 and 21b2 are formed on the front surface 21C. Slits 22b1 and 22b2 are formed on the back surface 22C.

[0158] The mattress 20C has, on its surface 21C, a plurality of slits 21b1 aligned along the longitudinal direction D1 and a plurality of slits 21b2 aligned along the width direction D2. The depths of the plurality of slits 21b1 differ from one another. The plurality of slits 21b1 includes, for example, a deep slit 21b1 and a slit 21b1 shallower than the deep slit 21b1. For example, a plurality of (for example, two) shallow slits 21b1 are formed between two deep slits 21b1 aligned along the longitudinal direction D1.

[0159] The depths of the multiple slits 21b2 are different from one another. The multiple slits 21b2 include, for example, deep slits 21b2 and slits 21b2 shallower than the deep slits 21b2. For example, multiple (for example, two or four) shallow slits 21b2 are formed between two deep slits 21b2 aligned along the width direction D2.

[0160] The mattress 20C has, on its back surface 22C, a plurality of slits 22b1 aligned along the longitudinal direction D1 and a plurality of slits 22b2 aligned along the width direction D2. The depths of the plurality of slits 22b1 are different from one another. The plurality of slits 22b1 include, for example, deep slits 22b1 and slits 22b1 shallower than the deep slits 22b1. For example, a shallow slit 22b1 is formed between two deep slits 22b1 aligned along the longitudinal direction D1.

[0161] The depths of the multiple slits 22b2 are different from one another. The multiple slits 22b2 include, for example, deep slits 22b2 and slits 22b2 shallower than the deep slits 22b2. For example, multiple deep slits 22b2 are lined up along the width direction D2, and multiple shallow slits 22b2 are lined up along the width direction D2 at a location different from the deep slits 22b.

[0162] As described above, in the bedding 1C according to the third embodiment, a plurality of slits having different depths are formed on each of the front surface 21C and the back surface 22C of the mattress 20C. On each of the front surface 21C and the back surface 22C, areas of the mattress 20C where deep slits are formed are more susceptible to deformation than areas of the mattress 20C where shallow slits are formed. As described above, by forming a plurality of slits having different depths on each of the front surface 21C and the back surface 22C, the mattress 20C can be locally deformed.

[0163] (Fourth embodiment) Next, a bedding 1D according to a fourth embodiment will be described with reference to Fig. 14. Fig. 14 is a partial side view showing a mattress 20D according to the fourth embodiment. The mattress 20D has a front surface 21B and a back surface 22A.

[0164] In the fourth embodiment, a mattress 20D has a slit 21b1 formed on the front surface 21B and a slit 22a1 formed on the back surface 22A. The shape of the slit 21b1 is different from the shape of the slit 22a1. The slit 21b1 extends in a U-shape in the height direction D3 of the mattress 20D. The slit 22a1 has a linear portion extending from the back surface 22A of the mattress 20D in the height direction D3 and an extended portion located at the end of the linear portion opposite the back surface 22A. The extended portion extends, for example, into a circular shape from the linear portion. As such, the mattress 20D of the fourth embodiment has multiple slits formed on the front surface 21B and the back surface 22A, each having a different shape from the other. The slits 21b1 and 22a1 allow the mattress 20D to follow the inflation of the airbag 30 (not shown) in the height direction D3. The bedding 1D of the fourth embodiment also provides the same effects as the bedding of the second embodiment.

[0165] (Fifth embodiment) Next, bedding 1E according to a fifth embodiment will be described with reference to FIG. 15. FIG. 15 is a partial side view showing a mattress 20E according to the fifth embodiment. The mattress 20E has a surface 21E that has a different shape from the surface 21. No slits are formed in the surface 21E. The surface 21E has a convex portion 21e1 and a concave portion 21e2. The convex portion 21e1 protrudes in the height direction D3 relative to the concave portion 21e2. The convex portion 21e1 and the concave portion 21e2 face in opposite directions. That is, in the height direction D3, the convex portion 21e1 protrudes and the concave portion 21e2 is concave.

[0166] The protrusions 21e1 and recesses 21e2 are alternately arranged along the width direction D2. The protrusions 21e1 and recesses 21e2 are also alternately arranged along the longitudinal direction D1. In a plan view, the protrusions 21e1 and recesses 21e2 are arranged in a lattice pattern. In a plan view, the protrusions 21e1 and recesses 21e2 may be arranged in a staggered pattern. The protrusions 21e1 and recesses 21e2 are provided in the center of the mattress 20E in the longitudinal direction D1 and the width direction D2.

[0167] The length of the protrusions 21e1 in the longitudinal direction D1 is the same as the length of the protrusions 21e1 in the width direction D2. The length of the protrusions 21e1 in the longitudinal direction D1 is, for example, 1 cm or more and 5 cm or less. The length of the recesses 21e2 in the longitudinal direction D1 is the same as the length of the recesses 21e2 in the width direction D2. The length of the recesses 21e2 in the longitudinal direction D1 is, for example, 1 cm or more and 5 cm or less. In each of the longitudinal direction D1 and the width direction D2, the protrusions 21e1 and the recesses 21e2 are arranged at intervals of, for example, 2 cm or more and 10 cm or less.

[0168] As described above, in the bedding 1E according to the fifth embodiment, the convex portions 21e1 and the concave portions 21e2 are formed on the surface 21E, so that when a person lies on the mattress 20E, the person's body pressure is effectively dispersed. Therefore, the sleeping posture of the person lying on the mattress 20E can be maintained favorably.

[0169] The mattress 20E of the fifth embodiment has a front surface 21E and a back surface 22A including slits 21a1 and 21a2. However, the configuration of the mattress 20E is not limited to this. For example, the back surface 22A of the mattress 20E may not have slits 21a1 and 21a2. Even in this case, the formation of the convex portions 21e1 and the concave portions 21e2 on the front surface 21E effectively distributes the body pressure of the person when they lie on the mattress 20E. This allows the person lying on the mattress 20E to maintain a good sleeping posture.

[0170] (Sixth embodiment) Next, bedding 1F according to a sixth embodiment will be described with reference to Fig. 16(a) and Fig. 16(b). Fig. 16(a) and Fig. 16(b) are cross-sectional views showing a side fabric 40 according to the sixth embodiment. The side fabric 40 has a boundary portion 43 in addition to an upper portion 41 and a lower portion 42. The boundary portion 43 is interposed between the mattress 20 and the airbag 30.

[0171] 16(a), the upper portion 41, the lower portion 42, and the boundary portion 43 constituting the side fabric 40 are each made of a non-stretchable material. In this case, the airbag 30 inflates both toward the mattress 20 and the opposite side from the mattress 20 in the height direction D3.

[0172] 16(b), the upper portion 41 and the boundary portion 43 are each made of a stretchable material. The lower portion 42 is made of a non-stretchable material. In this case, the stretchability of the lower portion 42 is lower than that of the upper portion 41 and the boundary portion 43, so that the airbag 30 inflates only toward the mattress 20 in the height direction D3.

[0173] As described above, in the bedding 1F according to the sixth embodiment, the inflation manner of the airbag 30 can be changed depending on the types of materials used for the upper portion 41, the lower portion 42 and the boundary portion 43 that make up the cover 40.

[0174] Seventh embodiment 17 is an exploded perspective view showing a bedding 1G according to a seventh embodiment. The bedding 1G includes a mattress 20G (bedding body) and a plurality of airbags 30G. The mattress 20G includes an upper mattress 201 (upper bedding) and a lower mattress 202 (lower bedding).

[0175] The upper surface 201a of the upper mattress 201 has unevenness formed thereon. The unevenness is provided over the entire upper surface 201a. The unevenness protrudes or recesses in the height direction D3. A plurality of slits 201B are formed on the lower surface 201b of the upper mattress 201. The slits 201B are aligned in both the longitudinal direction D1 and the width direction D2. More specifically, a plurality of slits 201B extending in the longitudinal direction D1 are aligned along the width direction D2, and a plurality of slits 201B extending in the width direction D2 are aligned along the longitudinal direction D1.

[0176] The lower mattress 202 is disposed opposite the upper mattress 201. The upper surface 202a of the lower mattress 202 is flat. A plurality of slits 202B are formed in the lower surface 202b of the lower mattress 202. The slits 202B are aligned along both the longitudinal direction D1 and the width direction D2. More specifically, the plurality of slits 202B extending in the longitudinal direction D1 are aligned along the width direction D2, and the plurality of slits 202B extending in the width direction D2 are aligned along the longitudinal direction D1.

[0177] The plurality of airbags 30G are interposed between an upper mattress 201 and a lower mattress 202. A lower surface 201b of the upper mattress 201 faces the airbags 30G. An upper surface 202a of the lower mattress 202 faces the airbags 30G.

[0178] The airbag 30G is shaped like a bag and is longer in the width direction D2 than in the longitudinal direction D1. For example, the bedding 1G has a plurality of airbag units each composed of a plurality of airbags 30G arranged along the longitudinal direction D1. The example in FIG. 17 shows two airbag units arranged along the longitudinal direction D1. One of the two airbag units is composed of three airbags 30G, and the other of the two airbag units is composed of two airbags 30G.

[0179] The airbag 30G is provided on a floor mat 36. The airbag 30G is, for example, fixed to the floor mat 36. The airbag 30G may be detachable from the floor mat 36. The floor mat 36 extends in both the longitudinal direction D1 and the width direction D2. The floor mat 36 has a rectangular shape with long sides extending along the longitudinal direction D1 and short sides extending along the width direction D2.

[0180] As described above, in the bedding 1G according to the seventh embodiment, the mattress 20G and the plurality of airbags 30G are integrated together, which makes it easier to manage the bedding 1G.

[0181] Various embodiments of the bedding according to the present disclosure have been described above. However, the bedding according to the present disclosure is not limited to the contents of the various embodiments described above, and may be further modified within the scope of the gist described in the claims. In other words, the shape, size, material, number, and arrangement of each part of the bedding according to the present disclosure can be changed as appropriate within the scope of the gist. The bedding according to the present disclosure may be a combination of multiple forms of the first to seventh embodiments described above.

[0182] For example, in the above-described embodiment, the bedding 1 has been described as having a rug 35 interposed between the airbag 30 and the base mattress 3. However, the bedding 1 does not have to have the rug 35. In this case, the lower part 42 of the side fabric 40 may be interposed between the airbag 30 and the base mattress 3. In this case, the airbag 30 may be fixed to the lower part 42 of the side fabric 40. In this case, the lower part 42 of the side fabric 40, which is disposed opposite the airbag 30, has low elasticity, thereby achieving the same effect as in the above-described embodiment.

[0183] In the above embodiment, an air control device 50 having an adapter 52 to which multiple air hoses 51 branch off from an air hose group 53 has been described. However, the configuration of the air control device is not limited to the configuration of the air control device 50 described above. For example, in the above embodiment, an example has been described in which the adapter 52 is placed at the feet of a person resting on the mattress 20. However, the adapter 52 may be placed on the head side of the person resting on the mattress 20 (the end on the headboard 2a side), or may be placed at any of the four corners of the mattress 20 in a plan view. In this way, the placement position and placement mode of the adapter 52 can be changed as appropriate.

[0184] Furthermore, the air control device does not have to have the adapter 52 and the air hose group 53. For example, the air control device may have the main body portion (the rectangular parallelepiped portion in FIGS. 1 and 2) described above and the air hose 51 extending from the main body portion. For example, the multiple air hoses 51 may branch off from the main body portion. However, when the air control device 50 has the air hose group 53 as in the above-described embodiment, there is an advantage in that the multiple air hoses 51 can be easily arranged.

[0185] In the above-described embodiment, an example has been described in which the air hose 51 is fixed onto the rug 35. However, if the bedding 1 does not have a rug 35, the air hose 51 may be fixed to the lower part 42 of the cover 40 made of a non-stretchable material. Even when the air hose 51 is fixed to the lower part 42, the same effects as in the above-described embodiment can be obtained.

[0186] In the above embodiment, an example has been described in which one airbag 31 acts on the user's chest (back) and two airbags 32 act on the user's waist. However, the number of airbags 31 may be two or more, and the number of airbags 32 may be one or three or more. The airbags 31 and 32 may be aligned along the longitudinal direction D1 or along the width direction D2. In this way, the number and arrangement of the airbags 31 and 32 can be changed as appropriate. Furthermore, the bedding may have at least one of an airbag acting on the neck, an airbag acting on the shoulders, an airbag acting on the arms, an airbag acting on the buttocks, and an airbag acting on the legs.

[0187] In the above embodiment, an example has been described in which four air hoses 51 are arranged side by side in the width direction D2 of the airbag 30. However, the air hoses 51 may be arranged at both ends of the airbag 30 in the longitudinal direction D1. For example, the air hoses 51 may be connected to the airbag 31 at the ends of the airbag 30 in the longitudinal direction D1. In this way, the arrangement of the air hoses 51 can also be changed as appropriate.

[0188] In the above embodiment, an example has been described in which the mattress 20 and the airbag 30 are integrated by the side fabric 40. However, the mattress 20 and the airbag 30 do not have to be integrated. That is, the mattress 20 and the airbag 30 may be separate bodies. At least one of the mattress 20 and the airbag 30 may be disposed outside the side fabric 40. In this way, the arrangement of the mattress 20, the airbag 30, and the side fabric 40 can be changed as appropriate.

[0189] In the above embodiment, an example was described in which the operation time for the sleep course, good morning course, and stretch course was approximately 10 minutes. However, the operation time for the sleep course, good morning course, and stretch course may be less than 10 minutes or may be longer than 10 minutes. In this way, the operation time of the airbag 30 for each course can be changed as appropriate.

[0190] In the above embodiment, an example has been described in which the number of air hoses 51 is four. However, the number of air hoses 51 may be three or less, or five or more. In this way, the number and arrangement of the air hoses 51 can be changed as appropriate.

[0191] In the above embodiment, an example was described in which the mattress 20A is provided with slits 21a1, 21a2, 22a1, and 22a2. In this example, the slits are provided on both the front surface 21A and the back surface 22A of the mattress 20A. However, the mattress 20A may only have slits 22a1 and 22a2 provided on the back surface 22A. Furthermore, the mattress 20A may only have slits 21a1 and 21a2 provided on the front surface 21A. In other words, the slits may be provided on only one surface of the mattress 20A in the height direction D3. In this way, the arrangement of the slits can be changed as appropriate.

[0192] In the above-described embodiment, an example has been described in which the arrangement interval d11 of the slits 22a1 and the arrangement interval d12 of the slits 22a2 are uniform. However, the arrangement intervals d11 and d12 do not have to be uniform. The number and arrangement of the slits 22a1 and 22a2 can also be changed as appropriate. The same applies to the above-described slits 21a1 and 21a2.

[0193] In the above-described embodiment, an example was described in which at least a portion of the air hose 51 was provided in the slits 22a1 and 22a2 in the back surface 22A of the mattress 20A. However, the air hose 51 may also be provided in the slits 21a1 and 21a2 in the front surface 21A of the mattress 20A. Even in this case, the amount of the air hose 51 exposed on the front surface 21A of the mattress 20A can be reduced, thereby achieving the same effect as in the above-described embodiment. In this case, the air hose 51 may also be provided in a through-hole that penetrates the mattress 20A. The through-hole penetrates from the front surface 21A to the back surface 22A of the mattress 20A. This allows the air hose 51 to be passed through the through-hole and connected to the airbag 30 located below the mattress 20A.

[0194] The mattress may not have a slit. Furthermore, in the above embodiment, the bedding 1 is described as having a mattress 20 as the bedding main body. However, the bedding may have a bedding main body other than a mattress. For example, the bedding may have a mattress as the bedding main body. In this way, the type of bedding main body is not particularly limited.

[0195] Next, bedding according to an embodiment will be described. Note that the present invention is not limited to the following embodiment. The bedding according to the embodiment is the same as the bedding 1 described above.

[0196] Various experiments using bedding according to the examples will be described below. Figure 18 is a diagram showing the relaxation scores calculated by the experiments. The "relaxation score" is an index for visualizing the relaxed state (degree of relaxation) of the subject. The higher the relaxation score, the more relaxed the subject is. The horizontal axis of Figure 18 indicates the good morning course, stretch course, and good night course. The vertical axis of Figure 18 indicates the relaxation score.

[0197] The top of the rectangular portion in Figure 18 indicates the average relaxation score. The top of the straight line extending upward from the rectangular portion in Figure 18 indicates the maximum relaxation score. Four subjects were used in measuring the relaxation score. To measure the relaxation score, each subject was fitted with an electroencephalograph while lying on the bedding, and their brain waves were acquired. An earphone-type electroencephalograph was used. Each subject wore the electroencephalograph for approximately 10 minutes during each of the Good Morning, Stretch, and Good Night courses. The relaxation score was then calculated using a program with a unique algorithm based on the intensity of the acquired brain wave data. Each subject's level of relaxation was determined by the presence or absence of alpha waves or by comparison with brain waves in other frequency bands. A high ratio of alpha waves to brain waves in other frequency bands is likely to increase the relaxation score. As shown in Figure 18, the Good Night course was suggested to be more relaxing for each subject than the Stretch and Good Morning courses.

[0198] Figure 19 shows the salivary amylase concentration (change) measured in the experiment. The amount of salivary amylase secreted changes depending on the sympathetic nervous function. Therefore, the degree of sympathetic nervous activity of the subject can be measured from the salivary amylase concentration. A high value of salivary amylase concentration indicates more active sympathetic nervous activity than a low value of salivary amylase concentration.

[0199] The horizontal axis of FIG. 19 represents the Good Morning Course, Stretch Course, and Good Night Course. The top of the rectangular portion shown in FIG. 19 represents the average value of salivary amylase concentration. The top of the straight line extending upward from the rectangular portion shown in FIG. 19 represents the maximum value of salivary amylase concentration. The vertical axis of FIG. 19 represents the salivary amylase concentration (unit: [kIU / L]). Salivary amylase is an enzyme. The International Unit (IU) is defined as a unit of enzyme amount. In salivary amylase tests, test results are obtained in units of [kIU / L] to indicate enzyme concentration. In addition, the amount of salivary amylase secreted increases, reflecting sympathetic nervous function due to stress, etc. Therefore, the amount of salivary amylase secreted (salivary amylase concentration) is used as an index of sympathetic nervous function and stress level. The number of subjects in the measurement of salivary amylase concentration was four. Salivary amylase concentrations were measured at the beginning and end of each course. For each course, salivary amylase concentrations were measured at time 0 and time 10. As shown in Figure 19, performing the Good Night course resulted in salivary amylase concentrations below 0 kIU / L (lower salivary amylase concentrations), suggesting that sympathetic nervous activity in each subject was suppressed. Furthermore, performing the Good Morning course resulted in salivary amylase concentrations above 0 kIU / L (increased salivary amylase concentrations), suggesting that sympathetic nervous activity in each subject was promoted.

[0200] FIG. 20 shows the subjective evaluations conducted in the experiment. The subjective evaluations were conducted by four subjects on a four-point scale before and after each course. The horizontal axis of FIG. 20 indicates the sense of relaxation, sense of stress, sense of refreshment, pain, muscle relaxation, and body tension. The vertical axis of FIG. 20 indicates the amount of change in the subjective evaluation.

[0201] The top of the rectangular portion shown in FIG. 20 (or the bottom if it is less than 0) indicates the average score given by the subjective evaluation. The top of the straight line portion extending upward from the rectangular portion shown in FIG. 20 indicates the maximum score given by the subjective evaluation. The bottom of the straight line portion extending downward from the rectangular portion shown in FIG. 20 indicates the minimum score given by the subjective evaluation. The scores given by the subjective evaluation were 4 ("very noticeable"), 3 ("somewhat noticeable"), 2 ("not noticeable at all"), and 1 ("not noticeable at all"). The score intervals given by the subjective evaluation were 1. That is, each subject was asked to answer only one of the scores 1, 2, 3, or 4. The subjective evaluation was conducted at the beginning and end of each course. The graph in FIG. 20 shows the average of the responses from four subjects.

[0202] For each course, subjective assessments were conducted at 0 minutes and 10 minutes. The change in subjective assessment for each subject (change over 10 minutes) for each course was calculated, and the average value was calculated. The "change" is the difference between the subjective assessment at the start of each course and the subjective assessment at the end of each course. For example, if the subjective assessment value at the start of each course was 2 and the subjective assessment value at the end of each course (10 minutes later) was 3, the change in subjective assessment would be 1. As shown in Figure 20, the results suggest that the "good night" course is suitable for before falling asleep and when you want to relax. The "good morning" course is suitable for when you wake up and want to refresh yourself. The results suggest that the "stretching" course is suitable for when you want to loosen up your body.
