Description

Pillow, pillow manufacturing method, pillow manufacturing system, computer program, and sleeping posture measuring device

The present invention relates to a pillow, a pillow manufacturing method, a pillow manufacturing system, a computer program, and a sleeping posture measuring apparatus.

According to the results of the 2016 National Health and Nutrition Survey, the percentage of those who have not been fully rested due to sleep in the last month is 19.7%, and this percentage is increasing year by year. According to the Ministry of Health, Labor and Welfare's “Sleep Guidelines for Health Promotion 2014”, it is confirmed that if there is a problem with sleep, anxiety, stress hormones increase, accidents occur, and depression is likely to occur. Short sleep times and insomnia have been shown to cause problems such as obesity, hypertension, impaired glucose tolerance, cardiovascular disease, and metabolic syndrome.
In order to improve such various problems relating to sleep, consumers are considering replacing bedding. According to a questionnaire survey, “Pillow” is listed as the first place to focus on good sleep and goods.

Conventionally, various pillows have been developed to meet the demand for a good sleep.
Patent Document 1 discloses a occipital region support unit that supports the occipital region when supine, a cervical region support unit that supports the cervical region, and a occipital region that is positioned on both sides of the occipital region support unit and the cervical region support unit. The occipital region and the cervical region are adjusted so that the height of the nose and chin is almost horizontal when lying on the back. There is disclosed a body corrective pillow in which the height of the head support portion is adjusted so that the cervical vertebra and the thoracic vertebra are substantially straight when lying down.

Japanese Patent Laid-Open No. 11-253287

Although the user's bone shape is different, the pillow of Patent Document 1 is a general-purpose product for everyone, so a gap is created between the user's head and the pillow, and the load on the head (body pressure) However, there is a problem in that the number of times that the device is applied is biased and the number of times of turning over is increased, and the user cannot obtain a feeling of rest due to sleep.
Customization is also required for bedding.
However, the “made-to-order pillow” currently on the market is said to measure the line on the midline with a rod-like thing, and change the padding that receives the head along that line, At the stage of measurement, it is classified into several types and several dozen types that are biased, and after roughly deciding the height, it is made at almost the same amount as the production site, so it cannot be said that it is sufficiently in line with the user's body shape. .

The present invention has been made in view of such circumstances, and a portion to which a load on the user's head is applied and the pillow are in close contact, body pressure is well dispersed, and shoulder and neck stiffness are prevented from occurring. An object of the present invention is to provide a pillow, a pillow manufacturing method, a pillow manufacturing system, a computer program, and a sleeping posture measuring apparatus that can reduce the number of times of turning over and obtain good sleep.

The pillow according to the present invention is formed by a 3D printer, and is based on a bone shape including at least a portion from the back of the head to the cheek or a portion from the face to the cheek of the user and the sleeping posture of the user. And a support part that supports the core part.

According to the present invention, since the core portion has a shape based on the bone shape and sleeping posture of the user, the portion to which the load of the user's head is applied and the pillow are in close contact, and the load on the head (body Pressure) is well dispersed, there is no sense of incongruity, and shoulder and neck stiffness and headache are suppressed. Rolling over can be done smoothly, and the number of times can be reduced, resulting in good sleep.

(Description of Embodiment of the Present Invention)
First, embodiments of the present invention will be listed and described. You may combine arbitrarily at least one part of the embodiment described below.

The pillow according to one aspect of the present invention is formed by a 3D printer, and includes a bone shape including at least a portion from the back of the head to the cheek or a portion from the face to the cheek of the user, and the sleeping posture of the user. And a support part that supports the core part.

Here, “a shape based on at least a bone shape including a portion from the back of the head to the cheek or a portion from the face to the cheek and the sleeping posture of the user” in addition to “the sleeping shape of the neck and shoulders” It is the meaning that "the shape at the time of a posture" may also be included.
The “shape based on the bone shape and the sleeping posture of the user” includes “the shape of the bone and the surrounding meat in the sleeping posture”.
In this aspect, the core part formed by the 3D printer has a shape based on the bone shape and the sleeping posture of the user. The core portion corresponds to a portion where the user's head is abutted and fixed when the user is lying on his back, lying down, or lying down, that is, the portion where the load is most applied. The head and the pillow are in close contact, the body pressure is well dispersed, there is no sense of incongruity, and the occurrence of stiff shoulders and necks and headaches is suppressed. Rolling over can be done smoothly, and the number of times can be reduced, resulting in good sleep.

In the pillow according to one aspect of the present invention, the core portion has a recess corresponding to the shape, size, and position information of an ear when the user lies down sideways.

Here, the concave portion includes the case of penetrating to the bottom of the pillow.
The ear protrudes from the head side, and the body pressure concentrates on the ear part in the horizontal sleeping posture. Therefore, the blood flow stops at the ear, the number of times of turning over so that the blood flow does not stagnate is increased, and the user may wake up before and after turning over. Taking an unreasonable posture so as not to crush the ears may cause stiffness in the neck or shoulder muscles. In this aspect, since the ears are accommodated in the recesses corresponding to the shape, size, and position information of the user's ears, and the head side part and the cheek load are applied to the parts other than the recesses, this problem is caused. Does not occur. Conventionally, there are pillows in consideration of ears, but the size, shape, and position of the ears vary greatly among individuals, and the above problems cannot be solved because they are not considered.

The manufacturing method of the pillow which concerns on 1 aspect of this invention acquires the 1st data which concerns on the bone shape containing the part from a user's at least the part from a back head to a cheek, or the part from a face to a cheek, and the said 1st data Based on the second data, the second data based on the user's lying-down posture or the lying-down posture and the horizontal sleeping posture is generated, and a pillow is manufactured using a 3D printer based on the second data.

In this aspect, the first data relating to the bone shape of the user is acquired, the second data based on the sleeping posture of the user is generated based on the first data, and the 3D printer is generated based on the second data. Since the pillow is manufactured using the pillow, the pillow according to the actual sleeping posture of the user can be obtained.
The pillow is manufactured based on the bone shape including the portion from the back of the user's back to the cheek (when lying on the back) or the portion from the face to the cheek (when lying on the bed), and the sleeping posture, where the pillow is most loaded at bedtime. Therefore, the user's body and the pillow can be brought into close contact with each other, the body pressure is well dispersed, there is no sense of incongruity, and the occurrence of stiff shoulders and necks and headaches are suppressed. Rolling over can be done smoothly, and the number of times can be reduced, resulting in good sleep.

In the method for manufacturing a pillow according to one aspect of the present invention, a core portion based on the second data and a covering portion including an elastic gel having a hardness of 0 to 12 are formed on a support portion using the 3D printer. .

In this embodiment, when using a highly repulsive and hard material for the core portion to shorten the pillow manufacturing time, the pillow can be obtained by using an elastic gel having a hardness of about the level of human skin that is also used for prosthetic devices. The surface of can be made to feel soft.

In the method of manufacturing a pillow according to one aspect of the present invention, the first data includes data relating to the shape, size, and position information of the user's ear, and has a recess corresponding to the data. The core part is formed.

In this aspect, since the ear is accommodated in the concave portion corresponding to the shape, size, and position information of the user's ear, and the head side portion and the cheek load are applied to the portion other than the concave portion, it is dispersed. The number of unnecessary rollovers to be performed more than necessary can be reduced. Since the adjustment of each part such as a distorted body joint while waking up is naturally performed by turning over, it is necessary to turn over itself. However, it is said that turning over caused by blood circulation inhibition such as crushing of ears has a different purpose and is likely to be turned over unnecessarily, causing shallow sleep.

The method for manufacturing a pillow according to one aspect of the present invention acquires the first data in a state where the head of a user in a sleeping position is suspended from the torso.

When humans are standing, they have power to support the spine, and when they are sleeping, they are relaxed and relaxed, so when standing or sitting and sleeping, the shape of bones and muscles Different. In this mode, since the first data is acquired in a state where the user's head in the sleeping position is suspended from the torso, a pillow that matches the shape of the actual sleeping position can be manufactured. When the measurement was performed while the user was sleeping, the sleeping posture data could be obtained, but even when the measurement was performed in the normal sleeping state, the lower surface was not visible from the side, and the shape of the lower surface could not be measured. In a water bed or the like made of vinyl that can penetrate the periphery of the head, the bottom surface shape may be measured from the side, but it is difficult to measure the exact shape. Moreover, there was a big difference from a normal sleeping posture, for example, the waist was too low, except for the user of the water bed, and the measurement data could not be utilized for sleep improvement.

A method for manufacturing a pillow according to one aspect of the present invention is based on the first data, and a model of the user's head is produced using the 3D printer, the model is rolled on an elastic body, Data relating to the user's lying-down sleeping position or lying-down sleeping position and sideways sleeping position is acquired.

In this mode, the model is rolled on the elastic body so as to reproduce the user's actual sleeping posture, for example, the angle of the head and shoulders when lying sideways to the left, how to curl, etc. The model can be rolled based on the user's request, and data relating to the lying-down sleeping position or the lying sleeping position and the lying-down sleeping position can be acquired. If there is motion capture data relating to the acquired sleeping posture, this may be used as with the model.

The pillow manufacturing system which concerns on 1 aspect of this invention is an acquisition apparatus which acquires the 1st data which concerns on the bone shape containing the part from a user's at least the part from a back head to a cheek, or the part from a face to a cheek, and said 1st A generating device that generates second data based on the user's lying-down or lying-down posture and a side-by-side sleeping posture, and a 3D printer that manufactures a pillow based on the second data.

In this aspect, the first data related to the bone shape of the user is acquired face-to-face, the second data is generated, and a part of the pillow is manufactured by the 3D printer. The user's body and pillow can be in close contact with each other's sleeping posture, the body pressure is well dispersed, there is no sense of incongruity, stiff shoulders and neck and headaches are suppressed, and the number of times that the rolling can be done smoothly and Can produce and hand over pillows that require less. After completion, it can be corrected and remanufactured on the spot.

In the pillow manufacturing system according to an aspect of the present invention, the 3D printer creates a model of the user's head based on the first data, and the generation device rolls the model on an elastic body. The second data is generated based on the moved data.

In this mode, the second data is generated by rolling the model on the elastic body so as to reproduce the actual sleeping posture of the user and rolling the model based on the user's request. can do. If there is motion capture data related to the acquired sleeping posture, the model may be rolled based on the data.

The computer program which concerns on 1 aspect of this invention acquires the 1st data which concerns on the bone shape containing the part from a user's at least the part from a back head to a cheek or the part from a face to a cheek to a computer, The said 1st data The second data based on the user's lying-down or lying-down posture and the side-by-side sleeping posture is generated, and a process of outputting the second data to the 3D printer is executed.

In this aspect, a pillow is obtained along the actual sleeping posture of the user.
Since the pillow is manufactured based on the bone shape including the portion from the back of the head to the cheek or the portion from the face to the cheek and the sleeping posture, the user's head and the pillow can be brought into close contact with each other. The pressure is well distributed, there is no sense of incongruity, shoulder and neck stiffness, and headaches are also suppressed. Rolling over can be done smoothly, and the number of times can be reduced, resulting in good sleep.

A sleeping posture measuring apparatus according to an aspect of the present invention includes a measuring unit including a frame, a sheet stretched over an opening surface of the frame, and a supporting unit that supports a human body in the sleeping posture, A part of the human body is opposed to the opening, the other part of the human body is supported by the support part, and the bone shape of the part is measured in a state in which the sheet is adjusted along the part.

In this embodiment, since it is possible to measure the bone shape that matches the sleeping posture of the actual human body with a weak force, it is possible to produce bedding such as pillows and mats that provide good sleep.

Hereinafter, the present invention will be specifically described with reference to the drawings illustrating embodiments thereof.
(First embodiment)
1 is a plan view of the pillow 1, FIG. 2 is a sectional view taken along the line II-II in FIG. 1, and FIG. 3 is a sectional view taken along the line III-III in FIG.
The pillow 1 includes a cover part 2, a height adjustment part 3, a support part 4, a core part 5, core parts 6 and 6, and a covering part 7.

The support portion 4 includes a synthetic resin material such as low-resilience urethane, has a semicircular shape in plan view, and has a shape recessed from both ends of the string toward the center. The shape of the support part 4 is not limited to this case.
The support part 4 has the recessed part 41 extended in a transversal direction in the center part of the longitudinal direction of the pillow 1, and has the recessed parts 43 and 43 extended in a transversal direction in the both ends part side of a longitudinal direction.
The cover 2 has a plurality of compartments (not shown) that contain materials such as urethane chips and soft polyester pipes. The height of each part of the pillow 1 is adjusted by adjusting the amount of the material accommodated in the accommodating part.
The height adjusting unit 3 is formed by superposing thin urethane, and adjusts the height.

The core portion 5 and the core portions 6 and 6 disposed on both sides thereof are formed by the recessed portion 41 and the later-described 3D printer 13 so as to fit into the recessed portions 43 and 43, respectively. It has a shape based on the bone shape including the part up to the cheeks and the user's sleeping posture. The sleeping posture includes a lying sleeping posture and left and right lateral sleeping postures.

In FIG. 1, the core portion 5 has a shape based on a supine posture, and the core portion 6 has a shape based on a sideways sleeping posture.
The core portion 5 has a through hole 51 at a substantially central portion in the longitudinal direction. The support part 4, the height adjustment part 3, and the cover part 2 have a through hole 42, a through hole 31, and a through hole 21 that are continuous with the through hole 51. In addition, it is not limited when it has the through- holes 21, 31, 42, 51. Further, without providing the through holes 21, 31, and 42, a concave portion 51 whose bottom surface coincides with the bottom surface of the concave portion 43 may be provided instead of the through hole 51. The through-hole 51 or the recess 51 is provided so that air permeability is improved and a line required for the head-shoulder is easily provided even by a person with a different occipital shape, but it is not always necessary to provide it. The shape of the core part 5 should just respond | correspond to a supine sleeping posture.

The core portion 6 further includes a through hole 61 corresponding to the shape, size, and position information of the ear when the user lies down sideways. In FIG. 1, the through hole 61 is schematically shown, but the through hole 61 is based on the exact shape, size, and position of each user's ear.
The bone shape data is extracted from first data acquired by the acquisition device 11 described later for each user. Data regarding the shape, size, and position of the ear is also acquired from the acquisition device 11 for each user.
The through hole 61 preferably has a shape that is 0.5 cm to 2 cm larger than the outer edge of each user's ear. Thereby, while turning over easily, the load of the head can be favorably supported by the portion other than the through hole 61 of the core portion 6. It is more preferable that the through hole 61 has a shape that is 1 cm to 1.5 cm larger than the outer edge portion.
The support part 4, the height adjustment part 3, and the cover part 2 have a through hole 44, a through hole 32, and a through hole 22 that are continuous with the through hole 61. Note that the through hole 44, the through hole 32, and the through hole 22 may not be provided, and instead of the through hole 61, a recess 61 whose bottom surface coincides with the bottom surface of the recess 43 may be provided.
In FIG. 1, the core part 5 and the core parts 6 and 6 are separated, but they may be made continuous.

The data relating to the sleeping posture can be created by reverse engineering software such as 3D CAD software based on the first data. That is, the first data can be rolled to obtain the data. The first data may be acquired using a sleeping posture measuring device 8 to be described later in a state where the head of the user in the sleeping posture is suspended from the trunk. In addition, a model including the user's head is prepared by a 3D printer 13 described later based on the first data, and the model is rolled on an elastic body such as a viscosity so that the trajectory of the sleeping posture is on the elastic body. And the data related to the trajectory may be acquired by the acquisition device 11. Further, the user's sleeping posture may be measured in advance by motion capture or the like, and data relating to the sleeping posture may be acquired. You may decide to acquire the data which concern on a user's sleeping posture with the acquisition apparatus 11. FIG.

Based on the data relating to the sleeping posture, the 3D printer 13 generates second data for forming the core parts 5, 6, 6 and outputs the synthetic resin from the 3D printer 13 based on the second data. , 6 and 6 are formed. Any material can be selected for the synthetic resin. The material may be changed for each of the core parts 5, 6 and 6 and for each part of the core part. For example, the core portion 6 corresponding to the lying-down posture can be easily turned over by using a material having higher resilience than the core portion 5 corresponding to the lying-down posture.

The covering portion 7 includes an elastic gel having a hardness of 0 to 12, and covers the portion of the support portion 4 where the core portions 5, 6, 6 are not provided. Even in the case of shortening the manufacturing time of the pillow using a highly repulsive and hard material for the core parts 5, 6, 6, the surface of the pillow 1 can be made soft by using the elastic gel. The core part 5, 6, 6 may be covered with the covering part 7.

As shown in FIG. 2, in the central portion in the longitudinal direction of the pillow 1, the support portion 4 has a shape close to a sleeping posture in which no spin is applied, for example, the spine draws a gentle S shape when lying on its back. . The shape of the support portion 4 is determined in advance based on the bone shape from the average person's head to shoulder. In addition, it is not limited to this shape.
The support portion 4 has the concave portion 41 and the concave portions 43 and 43 for receiving the core portion 5. The support 4 preferably has an angle between the axis of the head and the horizontal line of 5 to 20 degrees.
The surface of the core portion 5 has a shape corresponding to the shape of the occipital region of the supine sleeping posture for each user, so that the occipital region of each user and the pillow 1 can be brought into close contact with each other at the portion where the load is applied. The pressure disperses well. Therefore, there is no sense of incongruity, and the occurrence of stiff shoulders and necks and headaches is suppressed.
The core unit 5 may be configured such that the user's head is loosely fitted based on the acquired bone shape data and data relating to the sleeping posture.

As shown in FIG. 3, at the end of the pillow 1 in the longitudinal direction, the support 4 has a shape in which the spine is parallel to the bottom of the pillow 1, the top of the bedding, or both. In addition, it is not limited to this shape.
The ear protrudes from the side of the head, and the head body pressure concentrates on the ear portion in the horizontal sleeping posture. Therefore, the neck or shoulder muscles become stiff, the blood flow stops, the number of times of turning over is increased so that the blood flow does not stagnate, and the patient may wake up before and after turning over. By taking an unreasonable posture so as not to crush the ear, the neck or shoulder muscles may become stiff. In the present embodiment, the ear is accommodated in the through hole 61 corresponding to the shape, size, and position information of the user's ear, and corresponds to the cheek shape of the user's sideways sleeping posture other than the through hole 61. This portion does not cause this problem because the load applied to the head side and the cheek is dispersed. Rolling over can be done smoothly and good sleep can be obtained.

FIG. 4 is a block diagram showing the pillow manufacturing system 10 according to the present embodiment.
The pillow manufacturing system 10 is an acquisition device 11 that acquires imaging data, and a generation device that extracts the first data and data related to the shape, size, and position of ears from the imaging data and generates the second data. PC 12 and a 3D printer 13 that manufactures the pillow 1 based on the second data.
Examples of the acquisition device 11 include a 3D scanner. The acquisition device 11 preferably includes two or more cameras or lenses, and can simultaneously photograph the upper body of the user from a plurality of directions at a time in order to prevent movement and displacement. Although it is possible to shoot with only one camera, the shooting time can be shortened with two or more cameras. When the user is standing or sitting, take a swim cap or wrap a bandana to remove the effects of the hair so that the bone shape of the measurement site is as accurate as possible. Preferably it is done. In addition, although it is not limited when image | photographing a user's upper body, imaging data are acquired so that the bone shape including the part from a back head to a cheek at least can be extracted.
It is preferable to obtain not only the head but also the shapes of the neck bone, shoulder bone, scapula, and hip bone as the first data. The neck bone needs to have a shape that fits the S-curve, and in the case of a straight neck, it must have a shape that does not compress. If the shoulder bones and the hip bones are tied to the skull and neck bones, it is easy to roll over. Since the step between the scapula and the occipital region corresponds to the height of the pillow 1, it is preferable to measure.
In the present embodiment, “the shape of bones and meat when sleeping” is acquired without using X-rays. Determine the posture based on the correct sleeping posture, and measure the shape of bones and surrounding meat based on the posture. At that time, the bone shape can be imaged in the part where the bone shape can be confirmed with the naked eye, but for the user who has the part whose shape cannot be confirmed due to individual differences, the meat and bone shape in the posture will be measured. .

The PC 12 stores a pillow manufacturing program 123 described later. The PC 12 receives imaging data from the acquisition device 11, and at least the bone including the portion from the back of the user to the cheek and the shape data of the meat surrounding the sleeping posture, and the shape, size, and Extract data related to position.

In the case of the first manufacturing method of the pillow 1, the PC 12 simulates the user's movement based on the bone shape data using 3D CAD software or the like, and the user's lying-down posture or lying-down posture, and left and right lateral sleeping postures Based on this, second data for the 3D printer 13 for producing the core unit 5 or 6 is created. Instead of simulating the user's movement, the user may have the posture and posture. As described above, the second data is obtained based on the data related to the user's sleeping posture acquired by motion capture or the like. You may decide to create it. Further, the PC 12 simulates the user's movement based on the bone shape data and the movement data based on the user's sleeping posture (when lying on the side, curled up, etc.) or the user's request. You may decide.
The PC 12 outputs the second data to the 3D printer 13, and the 3D printer 13 creates the core unit 5 or 6 based on the second data.

Hereinafter, in the first manufacturing method, a case where the first data is acquired by the sleeping posture measuring device 8 will be described.
FIG. 5 is a perspective view showing the sleeping posture measuring device 8, and FIG. 6 is a schematic diagram showing a state in which the sleeping posture measuring device 8 is used to acquire the shape of the user's head and the meat surrounding the sleeping posture. is there.
The sleeping posture measuring device 8 supports a user in a sleeping posture, and a measuring unit 84 including a square frame-like frame body 82 and a sheet 83 such as a vinyl sheet stretched over the opening surface of the frame body 82. Support portions 81, 81, 81 are provided. The frame body 82 is not limited to a square frame, and the support portion 81 is not limited to a box shape. When there are three support parts 81, it is not limited. The support part 81 is arranged corresponding to the part of the user's body that is desired to be measured. When the part to be measured is the head, as shown in FIG. 6, one end side of the support parts 81, 81, 81 arranged in the longitudinal direction so that the head faces the opening of the measurement part 84. To place. When the part to be measured is the waist, the measurement unit 84 is disposed so as to face the waist, and the support units 81, 81, 81 are disposed so that the measurement unit 84 is sandwiched between the support units 81, 81.
The outer edge portion of the rectangular sheet 83 is attached to the upper edge portion of the frame body 82 so that the tension can be adjusted with a string or the like. The adjustment using the string is performed using, for example, a string stopper or a cord stopper. The sheet 83 may be other soft materials. The shape of the sheet 83 is not limited to a square shape. The sheet 83 is preferably thin and can recognize the bone shape well.
The support unit 81 may be adjusted so that, for example, several kinds of bedding used by the user at home and samples similar thereto are prepared in advance and can be measured in a sleeping posture as close as possible to the home.

As shown in FIG. 6, when the head is opposed to the measurement unit 84, the portion that extends from the shoulder to the top of the head protrudes from the support unit 81 so as to float in the air, and the other part of the user is the support unit 81, 81, 81. Support by. Then, the bone shape is measured by the acquisition device 11 in a state where the seat 83 is adjusted so as to follow the bone shape of the base of the neck from the head in the sleeping posture. The position of the seat 83 is determined by pulling or loosening the string etc. while checking whether it is easy to breathe and whether there are any parts that make it difficult or uncomfortable to sleep. Is preferred. When measuring, it is necessary to make fine adjustments so that the sheet 83 is not wrinkled in order to obtain a clean shape.
In the measurement, the relative height between the support part 81 and the measurement part 84 is adjusted. Considering the mat and mattress used by the user, when using the produced pillow 1, a sleeping posture with a natural spine curve that does not involve force is obtained. The height of the measurement unit 84 may be adjusted using a pantograph or the like.

The acquisition of the first data can be performed in either a so-called standing position or sitting position and a sleeping position = a lying position.
Measurement can be performed very easily by standing or sitting. As described above, the shape of the bone around the ear, which is particularly important for dispersing body pressure in the shape measurement of the temporal region, and the shape of the bone from the top of the occipital region to the neck in the occipital region are also not clear due to the hair. It can be measured by using a swimming cap or the like that can hold and collect hair.
However, as described above, the shapes of human bones and muscles differ between the standing or sitting position and the lying position.
The human spine draws a curve to support the standing posture, and because it is a physiological phenomenon to support the body by the muscular strength, the depth of the curved part of the neck is measured while standing or sitting, and the output When reflecting in the case, there is a risk of feeling uncomfortable when sleeping. It is preferable to acquire the first data using the sleeping posture measuring device 8.

It is known that humans perform body temperature regulation, recovery from physical and mental fatigue, improvement of immunity, memory organization, body tissue repair, etc. by turning over. When the sleeping posture measuring device 8 is used, it is necessary to measure in a posture in which turning over is easy.
The posture that makes it easy to turn over is that the head, neck, spine, and hips are laid in parallel and as straight as possible to the bottom of the bedding when lying on the side. It has been confirmed by experiments that it is not difficult for the sleeping posture that the head is connected to the bottom surface with a straight line as much as possible and the head is oriented slightly above the straight line.
A test was conducted to find an angle that could be turned over easily. When the angle was in the range of 10 to 20 degrees, a comfortable pillow could be provided to all the subjects. It is preferable that after the user takes a sleeping posture, the measurement is performed by adjusting the angle so that there is no sense of incongruity on the basis of a range of 10 to 20 degrees, and the adjustment is preferably performed by the cover portion 2 when the pillow 1 is manufactured.

The sleeping posture for sideways sleeping is measured in the same manner as for sleeping on the back.
The second data is obtained from the ear shape, size, and position information of the first data acquired in the standing position or the sitting position without measuring the sleeping position of the sideways sleeping using the sleeping position measuring device 8. The core portion 6 may be manufactured by obtaining the shape and position information of the through hole 61.

In the case of the second manufacturing method of the pillow 1, the PC 12 uses 3D CAD software or the like to create 3D data for manufacturing a model including the user's head and neck based on the bone shape data and output the 3D data to the 3D printer 13. The model may be a miniature. Further, the model may be only the head.

The operator rolls the model on an elastic body such as a viscosity, reproduces the user's sleeping posture, and acquires data related to the user's lying-down posture or lying-down posture and sideways sleeping posture by the acquisition device 11 To do. The worker can roll the model on the basis of the user's sleeping posture (in the case of sleeping on the side, curled up or the like) or on the request of the user. When there is motion capture data relating to the sleeping posture acquired in advance, the data may roll the model based on the data. The PC 12 inputs data related to the sleeping posture from the acquisition device 11 and outputs second data based on the data to the 3D printer 13, and the 3D printer 13 produces the core unit 5 or 6.

The 3D printer 13 produces the core portion 5 or 6, and the operator rolls the model on the elastic body to reproduce the sleeping posture, corrects the way of rolling, and second data based on this is obtained from the PC 12. And the corrected core portion 5 or 6 may be produced by the 3D printer 13.

In this embodiment, when producing a pillow for a user who lies on his / her face, the acquisition device 11 causes the first data relating to the bone shape of the user's cheeks to the face and the bone shape from the neck to the chest, and the nose. And data related to the mouth shape and position information. Then, data related to the sleeping posture is acquired for each user, and second data is created based on the acquired data. The pillow may be used only for lying down, and it may be adapted for sideways sleeping in consideration of the sideways sleeping posture.
For users who have symptoms of apnea syndrome, obtain data on the ideal sleeping posture of the user so that the tongue base of the user does not sink and the upper respiratory tract is narrowed. 2 Create data.
