Description

Technical Field

[0001] The present invention relates to a pillow for supporting a user's head.

Background Art

[0002] Pillows are used by many people to rest their heads during sleep (see, for example, Patent Document 1). The pillow of Patent Document 1 is formed in a curved shape that bulges downward, so that it naturally rests in a balanced state while rocking back and forth, enabling stable support of the user's head and neck.

Summary of the Invention

Problems to be Solved by the Invention

[0004] However, since a conventional pillow such as that of Patent Document 1 mainly supports the user's head, a gap is created between the user's neck and the pillow, futon, etc. when in use. When such a gap occurs, the user's cervical and thoracic vertebrae are burdened, resulting in a decrease in the quality of the user's sleep and potentially leading to sleep deprivation.

[0005] The present invention has been made to solve the above problems, and an object thereof is to provide a pillow that reduces the burden on the user's cervical and thoracic vertebrae.

Means for Solving the Problems

[0006] The pillow according to one aspect of the present invention includes a main fabric composed of a surface fabric facing upward during use, a back fabric facing downward during use, and a back fabric connecting the surface fabric and the back fabric, and a pair of side fabrics forming both side portions. The pair of side fabrics are respectively portions from the joint portion with the back fabric to the joint portion with the partition member, and include a first side fabric having a rectangular shape with the vertical direction during use as the short side direction in side view, and a second side fabric having a right triangle shape in side view and having the shorter side of the two sides sandwiching the right angle connected to the short side opposite to the back fabric of the first side fabric. The space surrounded by the main fabric, the pair of first side fabrics, and the partition member is filled with a first elastic member, and the space surrounded by the main fabric, the pair of second side fabrics, and the partition member is filled with a second elastic member.

Advantages of the Invention

[0007] The present invention has a main fabric, a pair of side fabrics forming both side portions, and a partition member that partitions the space covered by the main fabric and the pair of side fabrics. The spaces before and after the partition member are filled with elastic members respectively. And the pair of side fabrics have a rectangular first side fabric and a right triangle-shaped second side fabric. Therefore, while supporting the user's head and neck at the portion on the first side fabric side, the user's shoulders and scapulae can be supported at the portion on the second side fabric side, so that the burden on the user's cervical vertebrae and thoracic vertebrae can be reduced.

[0009] Embodiment A configuration example of a pillow 100 according to an embodiment will be described with reference to Figs. 1 to 5, 7 to 9, and 11 to 15. For convenience of explanation, xyz axes are shown in Figs. 1 to 5, 7 to 9, and 11 to 15 to specify the orientation of the pillow 100 when in use. When the pillow 100 is in use, the x-axis direction corresponds to the left-right direction, the y-axis direction corresponds to the front-back direction, and the z-axis direction corresponds to the up-down direction. In particular, the positive y-axis direction is the front side, and the positive z-axis direction is the upper side. These directions do not necessarily correspond to the pillow 100 when it is being carried, etc.

[0010] In each figure, some of the reference signs are appropriately omitted for the purpose of avoiding complication of the drawings. Also, in each figure, for portions of different constituent members having the same length, the same reference signs shall be used. Note that the pillow 100 is made by covering an elastic member such as cotton with a cloth, and since wrinkles, slack, errors due to sewing, etc. also occur, the length varies irregularly in all directions. However, in the following description, the designed length is exemplified, and double-headed arrows corresponding to the lengths of each part are shown for convenience in each figure.

[0011] As illustrated in FIGS. 1 to 5, the pillow 100 has a main fabric 10, a pair of side fabrics 30, and a partition member 50. The main fabric 10 has a front fabric 11 that faces upward during use, a back fabric 12 that faces downward during use, and a back fabric 13 that connects the front fabric 11 and the back fabric 12. The pair of side fabrics 30 form both side portions of the pillow 100 and are joined to the main fabric 10.

[0012] The partition member 50 is joined to the front fabric 11, the back fabric 12, and the pair of side fabrics 30, and partitions a space (hereinafter also referred to as the "inner space of the pillow") covered by the main fabric 10 and the pair of side fabrics 30. The partition member 50 is a belt-shaped member having a sewing margin, but each side may be curved. The width W of the pillow 100 is set to, for example, 62 cm and can be changed as appropriate. The width W of the pillow 100 is preferably made longer than the shoulder width of a relatively large-sized person. Each constituent member is joined by sewing.

[0013] Each of the pair of side fabrics 30 consists of a first side fabric 31 and a second side fabric 32 with the joint portion with the partition member 50 as a boundary. The first side fabric 31 is a portion from the joint portion with the back fabric 13 to the joint portion with the partition member 50, and has a rectangular shape with the vertical direction during use as the short side direction in side view. That is, the first side fabric 31 is arranged on the back fabric 13 side. The second side fabric 32 has a right-angled triangular shape in side view, and the shorter side of the two sides sandwiching a right angle is connected to the short side of the first side fabric 31 opposite to the back fabric 13.

[0014] In the pillow 100, the space surrounded by the main fabric 10, a pair of first side fabrics 31, and the partition member 50 is filled with a first elastic member C1, and the space surrounded by the main fabric 10, a pair of second side fabrics 32, and the partition member 50 is filled with a second elastic member C2. The first elastic member C1 and the second elastic member C2 may be the same member or different members. When referring to the first elastic member C1 and the second elastic member C2 without distinction, it is also referred to as an "elastic member".

[0015] The elastic member is preferably one that is composed of materials such as cotton that are joined in a separable manner or a plurality of elastic bodies and is easy to adjust the filling amount. As the cotton constituting the elastic member, for example, polyester medium cotton for bedding having appropriate elasticity, easy to cut and join, and excellent in heat retention, such as "FT DREAMTHERMO (registered trademark)" jointly developed by Toray Industries, Inc. and Toray International Co., Ltd., is preferable. By using cotton as the elastic member, it is possible to design so that heat does not accumulate inside the pillow 100.

[0016] Here, with respect to the pillow 100, the portion on the rear side of the partition member 50, that is, the portion on the back fabric 13 side of the partition member 50 is referred to as the head support portion 110, and the portion on the front side of the partition member 50, that is, the portion on the side opposite to the back fabric 13 of the partition member 50 is referred to as the scapula support portion 120. The pillow 100 of the present embodiment has a separate structure using the partition member 50, and the elastic member does not flow back and forth between the head support portion 110 that supports the head and the like and the scapula support portion 120 that supports the scapula and the like. Therefore, the height and elasticity of each of the head support portion 110 and the scapula support portion 120 can be maintained.

[0017] As illustrated in FIG. 3, in the pillow 100 in a state where no load is applied, it is preferable to adjust the amount of the elastic member so that the maximum thickness H in the vertical direction is longer than the length Tz of the short side of the first side fabric 31. The first side fabric 31 shares the short side opposite to the back fabric 13 with the second side fabric 32. Therefore, the length of the shorter side among the two sides sandwiching the right angle of the second side fabric 32 is also Tz.

[0018] In FIG. 3, a side fabric 30 including a first gusset 31 with a short side length Tz of about 11 cm and a long side length L1 of about 32 cm is illustrated. The length L1 is preferably about twice the stable length S described later. In FIG. 3, a side fabric 30 including a second gusset 32 with a long side length L2 of about 20 cm among the two sides sandwiching a right angle is illustrated. The size of the side fabric 30 in the above description does not include the seam allowance, that is, it corresponds to the size of the area surrounded by the seams.

[0019] The second gusset 32 is preferably set so that the support angle θ, which is the inclination angle on the side opposite to the first gusset 31 in a right triangle shape, that is, the inclination angle not facing the first gusset 31, is about 30 degrees. The second gusset 32 shares the short side (the shorter of the two sides sandwiching the right angle) with the first gusset 31, and the support angle θ is the angle formed by the hypotenuse and the middle side (the longer of the two sides sandwiching the right angle) in the right triangle shape of the second gusset 32.

[0020] The support angle θ of the second gusset 32 is set based on the physiological curvature of the spine (vertebral column). More specifically, when viewed from the side, the spine draws an S-shaped curve as shown in FIG. 6, and this S-shaped curve is called the physiological curvature. Among the physiological curvatures of the spine, the curvature of the cervical vertebrae is called "lordosis", and the curvature of the thoracic vertebrae is called "kyphosis", but the support angle θ of the second gusset 32 is set based on the bending angle β related to kyphosis (see FIG. 6).

[0021] The bending angle β related to kyphosis is about 20 degrees to 40 degrees, but in reality, people with a bending angle β of about 25 degrees account for a fairly large range. Since the pillow 100 is filled with an elastic member, when a load is applied to the pillow 100, the scapula support portion 120 sinks (concaves) together with the head support portion 110. Therefore, in order to make the inclination angle of the second gusset 32 about 25 degrees in the state where the user's load is applied, it is preferable to set the support angle θ to about 28 degrees to 30 degrees. The support angle θ may be adjusted according to the filling amount and material of the elastic member.

[0022] Incidentally, the weight of the upper part of a person's scapula has less individual variation compared to the person's total body weight. Therefore, a support angle θ for a relatively large number of people can be set according to the filling amount, material, etc. of the elastic member. The second side fabric 32 is preferably set such that the support angle θ is 23 degrees or more and 44 degrees or less, and more preferably such that the support angle θ is 25 degrees or more and 35 degrees or less. The second side fabric 32 may be set such that the support angle θ is 25 degrees or more and 30 degrees or less on the premise that the bending angle β is in the range of 20 degrees to 25 degrees.

[0023] The length L2 of the longer side of the two sides sandwiching the right angle of the second side fabric 32 is preferably 18 cm or more and 22 cm or less, and more preferably 19 cm or more and 21 cm or less. The length Tz of the short side of the first side fabric 31 is preferably 9 cm or more and 13 cm or less, and more preferably 10 cm or more and 12 cm or less. When the length L2 is 20 cm and the length Tz is 11 cm, the support angle θ is approximately 28.81° according to the following formula (1). When the length L2 is 20 cm and the length Tz is 11.5 cm, similarly, the support angle θ is approximately 29.90°. When the length L2 is 20 cm and the length Tz is 12 cm, similarly, the support angle θ is approximately 30.96°. When the length L2 is 19 cm and the length Tz is 11 cm, similarly, the support angle θ is approximately 30.07°. When the length L2 is 21 cm and the length Tz is 12 cm, similarly, the support angle θ is approximately 29.74°.

[0024]

Number

[0025] As illustrated in FIGS. 4 and 5, the back fabric 12 is provided with a first opening / closing member K1 for adjusting the filling amount of the first elastic member C1 and a second opening / closing member K2 for adjusting the filling amount of the second elastic member C2. The first opening / closing member K1 and the second opening / closing member K2 illustrated in each figure are constituted by fasteners.

[0026] As illustrated in FIG. 5, in the pillow 100 of the present embodiment, an auxiliary member 1m for assisting the insertion and removal of the first elastic member C1 is attached around the first opening / closing member K1, and an auxiliary member 2m for assisting the insertion and removal of the second elastic member C2 is attached around the second opening / closing member K2. The auxiliary member 1m and the auxiliary member 2m are formed by sewing one or two pieces of cloth in a loop shape. One opening of the auxiliary member 1m is sewn to the first opening / closing member K1, and the first elastic member C1 can be filled, replenished, and extracted through the other opening. One opening of the auxiliary member 2m is sewn to the second opening / closing member K2, and the second elastic member C2 can be filled, replenished, and extracted through the other opening.

[0027] In the pillow 100 of the present embodiment, the main fabric 10 is composed of a first fabric 10A that constitutes a part of the surface fabric 11, the back fabric 13, and the inner fabric 12, and a second fabric 10B that is the remaining part of the inner fabric 12, so that the first opening / closing member K1 and the second opening / closing member K2 can be easily sewn. That is, the first opening / closing member K1 and the second opening / closing member K2 are sewn to the central part of the joint between the first fabric 10A and the second fabric 10B.

[0028] The length Th from the joint with the surface fabric 11 to the joint with the back fabric 12 at the central part in the left-right direction of the partition member 50 may be equal to the length Tz of the side part, or may be a length (Tz + P) obtained by adding an adjustment length P to the length Tz of the side part. The adjustment length P is set to, for example, 0.5 cm and can be changed as appropriate. The adjustment length P is preferably set to 1 cm or less. Note that since the length of the side part of the partition member 50 is equal to the length of the short side of the first side fabric 31, the same reference symbol "Tz" is used.

[0029] Here, with reference to the schematic diagrams of FIGS. 7 to 9, the shape of the partition member 50 will be specifically described. In FIGS. 7 to 9, the sewing part is indicated by a broken line, and the inside of the broken line is the part that actually partitions the pillow inner space, and the outside of the broken line is the sewing allowance n. The partition member 50 may have a rectangular shape with straight sides as shown in FIG. 7 (Tz = Th).

[0030] As shown in FIG. 8, the partition member 50 may have a shape in which one of the long sides in the rectangular shape is curved outward. In FIG. 8, the partition member 50 having a shape in which the long side arranged on the upper side during use is curved outward is illustrated. In the partition member 50 illustrated in FIG. 8, due to the curvature of one long side, the length Th is longer than the length Tz by the curved length a. The curved length a corresponds to the adjustment length P (a = P).

[0031] As shown in FIG. 9, the partition member 50 may have a shape in which two long sides in the rectangular shape are curved outward. In the partition member 50 illustrated in FIG. 9, due to the curvature of each long side, the length Th is the length obtained by adding the curved length a and the curved length b to the length Tz. The sum of the curved length a and the curved length b corresponds to the adjustment length P (a + b = P).

[0032] As shown in FIGS. 8 and 9, by making the length Th longer than the length Tz, the central portion where the user's load is large can be made higher than the side portions. That is, with such a configuration, since the amount of the elastic member in the left - right central portion is larger than that in the side portions, the front - rear inclination of the scapula support portion 120 can be made more uniform across the left and right.

[0033] The pillow 100 has a belt - shaped gathering member 60 joined to the front fabric 11 and the back fabric 12 at a position on the left - right center closer to the back fabric 13 side than the partition member 50. The gathering member 60 is joined to the front fabric 11 and the back fabric 12 at a position on the back fabric 13 side by a stable length S from the partition member 50. The stable length S is set to, for example, 15 cm or 16 cm and can be changed as appropriate.

[0034] Here, referring to FIGS. 6 and 10, the setting of the stable length S and its advantages will be described. As shown in FIG. 6, the spine is divided into the cervical vertebrae (7 pieces), the thoracic vertebrae (12 pieces), the lumbar vertebrae (5 pieces), the sacrum (5 pieces), and the coccyx (3 to 5 pieces). Among them, the cervical vertebrae are numbered C1 to C7 in order from the top, and the thoracic vertebrae are numbered T1 to T12. Therefore, in the following, these numbers will be used for the description.

[0035] FIG. 10 is a table that organizes the lengths from the EOP (external occipital protuberance) to C7 and the lengths from the EOP to T5 for a plurality of people with different heights. From this table, it can be seen that the length from the EOP to T5 has a large variation among people, while the individual differences in the length from the EOP to C7 are small. Note that among people with a height of 180 cm or more, there are those whose length from the EOP to C7 is within 16 cm, but in FIG. 10, people who do not fall within this range are deliberately exemplified.

[0036] Since the partition member 50 has the shape exemplified in FIG. 7 and the like, the pillow 100 filled with an appropriate amount of elastic member will sink somewhat at the location of the partition member 50. Here, if the pillow 100 is configured such that the stable length S is 15 cm or more and 19 cm or less, when an ordinary person uses the pillow 100, C7 (the 7th cervical vertebra) or its vicinity will hit the location of the partition member 50. The pillow 100 with a stable length S of 14 cm or more and 17 cm or less is considered to be particularly suitable for people with a height of 140 cm or more and 180 cm or less.

[0037] In a pillow where the location where the user's C7 hits is flat front and back, the area around the protrusion of C7 is pushed upward, the neck bends upward, and the chin faces upward. Therefore, a burden is imposed on the neck, which may lead to pain in the neck during or after sleep. In this regard, for the pillow 100 set within the range where the stable length S is 15 cm or more and 19 cm or less, due to the dent at the location of the partition member 50, extension is applied to the C7 of many users, and the curvature of the user's neck base is guided to a natural physiological curvature. Therefore, the burden on the user's neck can be reduced, and the occurrence of pain can be suppressed. However, the pillow 100 can also be manufactured by custom order or have a stepwise size setting according to height (for example, a two-step setting for those with a height less than 180 cm and those with a height of 180 cm or more). In addition, the stable length S may be set shorter than 14 cm or longer than 19 cm. Note that the pillow 100 with a stable length S of 14 cm or less is also suitable for children.

[0038] The length Ts of the gathering member 60 from the joint with the outer fabric 11 to the joint with the inner lining 12 may be set to be equal to or less than the length Tz in the short direction of the first side fabric 31. The length Ts corresponds to the length of the gathering member 60 excluding the seam allowance. The difference (Tz - Ts) between the length Tz and the length Ts is preferably 2 cm or less, more preferably 1 cm or less. The length Ts of the gathering member 60 may be in the range of not less than the length obtained by subtracting 2 cm from the length Tz in the short direction of the first side fabric 31 and not more than the length obtained by adding 1 cm to the length Tz in the short direction of the first side fabric 31 (Tz - 2 cm ≤ Ts ≤ Tz + 1 cm). That is, the length Ts of the gathering member 60 may be longer than the length Tz in the short direction of the first side fabric 31. The width Vs of the gathering member 60 is set to, for example, 6 cm and can be changed as appropriate.

[0039] Here, referring to FIGS. 11 and 12, the size of the pillow 100 filled with an appropriate amount of elastic member will be supplemented. FIG. 11 is a schematic cross-sectional view taken along line A-A of FIG. 2. FIG. 12 is an explanatory view in which the outer shape (two-dot chain line) of the side fabric 30 is superimposed on the schematic cross-section taken along line A-A of FIG. 2. In FIGS. 11 and 12, the cross-sectional shapes of the main fabric 10, the partition member 50, and the gathering member 60 are simplified and their thicknesses are exaggerated for easy understanding. In FIG. 11, the first opening / closing member K1 and the second opening / closing member K2 are simplified, and in FIG. 12, these are omitted. In FIGS. 11 and 12, the auxiliary members 1m and 2m are omitted, and in FIG. 12, the elastic member is omitted.

[0040] In the head support portion 110, the outer fabric 11 is pulled downward and the inner lining 12 is pulled upward by the gathering member 60. Therefore, the length Ts of the gathering member 60 is shorter than the maximum thickness Ta of the portion behind the gathering member 60 and the maximum thickness Tb of the portion in front of the gathering member 60 in the head support portion 110. Thus, the user's head can be stably supported with the gathering member 60 as the center.

[0041] Since the length Th of the partition member 50 is approximately the same as the length Tz, in the pillow 100 filled with an appropriate amount of elastic member, the partition member 50 pulls the surface fabric 11 downward and the back fabric 12 upward. Therefore, the length Th of the partition member 50 is shorter than the maximum thickness Tb of the front part and the maximum thickness Tc of the scapula support part 120 compared to the pulling member 60. Therefore, a dent occurs at the location of the partition member 50.

[0042] The head support part 110 is thicker on both sides where the pulling member 60 does not exist than at the center left and right where the pulling member 60 exists. On the other hand, the scapula support part 120 is thicker at the center left and right than on both sides where the right-angled triangular second side fabric 32 exists. Incidentally, for the pillow 100 of the present embodiment, the following relationship holds among the length Tz, the length Th, and the length Ts. ·Length Tz ≤ Length Th ·Length Tz ≥ Length Ts ·Length Th ≥ Length Ts

[0043] Subsequently, referring to FIGS. 13 to 15, the usage state of the pillow 100 by the user will be described. FIG. 13 is an explanatory diagram illustrating a state where the user is about to place the head and scapula on the pillow 100. FIG. 14 is an explanatory diagram illustrating a state where the user has placed the head and scapula on the pillow 100. FIG. 15 is an explanatory diagram illustrating a state where the user is using the pillow 100 in a lateral position. In FIGS. 13 to 15, the user is illustrated by a dashed line.

[0044] When the user uses the pillow 100, for example, as shown in FIG. 13, the user places the shoulders on the scapula support portion 120, and then, as shown in FIG. 14, places the upper part of the neck on the head support portion 110. At this time, if the position of the approximate EOP of the head is deviated from the position of the alignment member 60, the user will feel discomfort and thus perform position adjustment. When the jaw is overly upward during sleep, the root of the tongue is likely to fall into the back of the throat. When the root of the tongue falls into the back of the throat (so-called tongue root sinking), it may lead to SAS (sleep apnea syndrome) or cause snoring. In this regard, since the pillow 100 can provide a natural sleeping posture for the user using it as shown in FIG. 14, it is possible to suppress the occurrence of SAS and snoring.

[0045] For example, when the user is sleeping in the side lying position, such as after turning over, as shown in FIG. 15, the user's shoulders will be located at the position of the partition member 50. In the pillow 100, since there are some recesses at the position of the partition member 50, the user's shoulders can fit well into the recesses. Therefore, even when the user is sleeping in the side lying position, it is possible to provide a stable sleeping comfort for the user and reduce the burden on the user's shoulders.

[0046] As described above, the pillow 100 in the present embodiment includes a main fabric 10 composed of a surface fabric 11, a back fabric 12, and a back surface fabric 13, a pair of side fabrics 30 forming both side portions and joined to the main fabric 10, and a partition member 50 joined to the surface fabric 11, the back fabric 12, and the pair of side fabrics 30 and partitioning the space covered by the main fabric 10 and the pair of side fabrics 30. Elastic members that can be divided are filled in the spaces in front of and behind the partition member 50. And each of the pair of side fabrics 30 has a rectangular first side fabric 31 with the vertical direction in use as the short side direction, and a second side fabric 32 that is a right triangle and has the shorter side of the two sides sandwiching a right angle connected to the short side opposite to the back surface fabric 13 of the first side fabric 31. Therefore, while the portion on the first side fabric 31 side, that is, the head support portion 110 stably supports the user's head and neck, the portion on the second side fabric 32 side, that is, the scapula support portion 120 can stably support the user's shoulders and scapulae, so that the burden on the user's cervical vertebrae and thoracic vertebrae can be reduced.

[0047] That is, the pillow 100 has a separate structure using the partition member 50. Since the elastic member does not move back and forth in the regions before and after the partition member 50, the heights and elasticities of the head support portion 110 and the scapula support portion 120 can be stably maintained. Further, the side fabric 30 has a second side fabric 32 in the shape of a right triangle that slopes from around the user's C7 toward T4, and the user's back side is connected to a futon or the like with a natural slope. Therefore, since there is no step at the portion where the user's back hits, the user can sleep comfortably in a relaxed state as if receiving treatment.

[0048] The second side fabric 32 is preferably configured such that the support angle θ, which is the inclination angle on the side opposite to the first side fabric 31 in the right triangle shape, is 23 degrees or more and 44 degrees or less. Thereby, it is possible to provide a sleeping posture along the natural physiological curvature to the user using the pillow 100. If the support angle θ of the second side fabric 32 is 25 degrees or more and 35 degrees or less, it becomes possible to provide a sleeping posture along the natural physiological curvature to more users.

[0049] The pillow 100 has a strip-shaped gathering member 60 joined to the surface fabric 11 and the back fabric 12 at the left-right center position on the back fabric 13 side with respect to the partition member 50. The length Ts of the gathering member 60 is preferably within the range of not less than the length obtained by subtracting 2 cm from the length Tz in the short direction of the first side fabric 31 and not more than the length obtained by adding 1 cm to the length Tz in the short direction of the first side fabric 31 (Tz - 2 cm ≤ Ts ≤ Tz + 1 cm). By doing so, the portion of the gathering member 60 can be recessed by filling an appropriate amount of elastic member, so that the user's head can be stably supported at that portion.

[0050] The attaching member 60 may be joined to the front fabric 11 and the back fabric 12 at a position on the back fabric 13 side by a stable length S from the partitioning member 50. The stable length S may be set to 15 cm or more and 19 cm or less. With such a configuration, the C7 of the user or the vicinity thereof when the pillow 100 is in use will hit the location of the partitioning member 50. Therefore, the C7 of the user when the pillow 100 is in use is stretched, and the bending of the neck can be guided to a natural physiological curvature, so that the burden on the user's neck can be reduced and the occurrence of pain can be suppressed.

[0051] The partitioning member 50 is formed in a strip shape, but does not necessarily form an exact rectangle. For example, the partitioning member 50 may be configured such that the length Th from the joining location with the front fabric 11 to the joining location with the back fabric 12 in the central portion in the left-right direction is within a range of not less than the length (Tz) of the side portion and not more than the length obtained by adding 1 cm to the length (Tz) of the side portion. Within such a range, in the pillow 100 filled with an appropriate amount of elastic member, the location of the partitioning member 50 can be significantly recessed, so that the C7 of the user during use can be stretched and the bending of the user's neck can be guided to a natural physiological curvature.

[0052] The length L2 of the longer side of the two sides sandwiching the right angle of the second side fabric 32 may be set to 18 cm or more and 22 cm or less. In this way, the pillow 100 can gently cover the user from the head to the scapula. That is, at least the portion from the user's head to T4 can be stably supported by the pillow 100, and the user's body can be rested in a natural state. The first opening / closing member K1 and the second opening / closing member K2 may be provided on the back fabric 12. In this way, the filling amount of the elastic member can be freely adjusted, so that adjustments for each user, adjustments according to the physical condition and mood, etc. can be made for the height and elasticity of the pillow 100.

[0053] The above-described embodiments are merely examples of the pillow according to the present invention, and the technical scope of the present invention is not limited to these aspects. For example, in each figure, the separate-structured pillow 100 using one partition member 50 is illustrated, but it is not limited thereto. For example, the pillow 100 may be manufactured by separately creating a first part having the same shape as the head support part 110 and a second part having the same shape as the scapula support part 120 and joining them. In this case, the portion where the first part and the second part abut becomes the partition member 50. The partition member 50 may be configured such that the length Th of the central portion in the left-right direction is shorter than the length (Tz) of the side portion.

[0054] In the present embodiment, the main fabric 10 composed of the first fabric 10A and the second fabric 10B is illustrated, but it is not limited thereto. For example, the main fabric 10 may be composed of a single piece of cloth, or may be composed of three or more pieces of cloth. The first opening / closing member K1 and the second opening / closing member K2 are not limited to zippers, and may be constituted by opening / closing members such as hook-and-loop fasteners, hooks, buttons, and buttonholes. The pillow 100 may not have at least one of the auxiliary member 1m and the auxiliary member 2m. The elastic member may be a synthetic fiber or a natural fiber. The elastic member may be feathers (down), quills (feathers), as well as wool, cotton, etc. However, as the elastic member, cotton having appropriate elasticity and being easy to divide and combine is desirable. The joining of each constituent member may be automatic sewing using a dedicated machine, in addition to sewing by hand or using a sewing machine. The sizes and shapes of the respective constituent members in the above description are merely examples, and may be appropriately changed and adjusted.
