The pillow can reduce load on the cervical vertebrae mounting part of the back of the head of the user in the supine posture and may hold the neck of the user in the supine posture in a natural posture by receiving everything around the posterior parietal, the part on the cervical vertebrae side, or the part on the temporal region side of the user in the supine posture by the posterior parietal reception part.SELECTED DRAWING: Figure 2

Description

[Technical Field]

[0001] The present invention relates to a pillow, and more particularly to a pillow that can keep the neck in a natural position without applying excessive force to the neck and shoulders when lying on one's back. [Background technology]

[0002] If unnecessary stress is placed on the muscles around the neck, shoulders, or back while sleeping, it can cause stiff shoulders or stiff necks, so it is important to be able to sleep in a comfortable supine position that does not put unnecessary stress on the muscles.

[0003] For example, a pillow has been proposed that has elevated side pillow sections on both sides of the central pillow section, so that when lying on one's back, the back of the head or the back of the head and cervical vertebrae can be placed in a comfortable upward position on the central pillow section, while when lying on one's side, the sides of the head can be placed in a comfortable sideways position on the side pillow sections (Patent Document 1, Patent Document 2, Patent Document 3, Patent Publication 4). [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Utility Model Registration No. 3077473 [Patent Document 2] Japanese Patent Publication No. 2020-110293 [Patent Document 3] Patent Publication No. 2021-53254 [Patent Document 4] Japanese Patent Application Publication No. 11-253286 DISCLOSURE OF THE INVENTION [Problem to be solved by the invention]

[0005] Incidentally, the shape of the back of the head varies from person to person in terms of the curvature of the back of the head, and it can protrude backward or be flat. Even if it protrudes backward, it can protrude significantly or barely protrude at all and be nearly flat.

[0006] However, with the pillows described in Patent Documents 1 to 4, depending on the shape of the back of the head, the shape of the pillow may not match the shape of the back of the user's head, causing the cervical vertebrae to not assume a natural shape when lying on one's back, and causing excessive pressure to be applied to the neck and shoulders.

[0007] In view of the above problems, the present invention aims to provide a pillow that can keep the neck in a natural position without applying excessive force to the neck and shoulders when lying on one's back. [Means for solving the problem]

[0008] Therefore, when the most protruding part of the back of the user's head is the occipital vertex, the pillow of the present invention has a three-dimensional shape that has a occipital vertex support portion that can support the entire circumference of the occipital vertex of a user in a supine position, either the cervical or temporal part, when placed on the floor, and a cervical vertebrae support portion that is continuous with the occipital vertex support portion and can support the cervical vertebrae of a user in a supine position, and the cervical vertebrae support portion has at least the width of the cervical vertebrae of a user in a supine position, and by the occipital vertex support portion supporting the entire circumference of the occipital vertex of the user in a supine position, either the cervical or temporal part, the load on the occipital vertebrae of the user in a supine position on the cervical vertebrae support portion is reduced and the neck of a user in a supine position can be kept in a natural position.

[0009] One of the features of the present invention is that the pillow has a three-dimensional shape with a posterior parietal support portion and a cervical vertebrae support portion, and by having the posterior parietal support portion support the entire area around the posterior parietal of a user in a supine position, either the part on the cervical vertebrae side or the part on the temporal side, the weight on the occipital region can be shared by the posterior parietal support portion, and the neck can be kept in a natural position without applying excess force to the neck, neck area or shoulders of a user in a supine position.

[0010] As a result, you will not suffer from stiff shoulders, stiff necks, or arm pain, and you can also prevent modern-day illnesses such as headaches and physical discomfort of unknown causes, as well as stiff necks caused by overuse of computers and smartphones.

[0011] For adult men and women, the neck width is about 9 cm to 12 cm, and the neck length is about 9 cm to 11 cm, so the cervical support part should be about 10 cm x 10 cm in size. Also, for children, for example, an average sixth grader, the neck width is about 9 cm, and the neck length is about 8 to 9 cm, so the back of the head support part can be made a little smaller for children.

[0012] The filling material for the pillow can be anything that provides cushioning, such as synthetic resin foam beads that flow when pressed, molded synthetic resin beads or plastic pipes, cotton that deforms when pressed, polyurethane foam, polyethylene fiber, polyester fiber, or a three-dimensional mesh structure in which these fibers are intricately entangled, a three-dimensional structure made from elastomer resin, such as a polyester-based elastomer resin, pipes resembling short straws, or buckwheat husks. When using foam beads or molded beads, it has been confirmed that a comfortable sleep can be achieved if the average particle size is between 0.5 mm and 10 mm, preferably between 0.5 mm and 2 mm.

[0013] According to the present invention, the pillow has a double cover structure with an inner and outer cover, the inner cover contains the above-mentioned internal components, and an outer cover of appropriate dimensions is selected for the outer cover, and the internal components of the inner cover can be compressed or stretched, thereby expanding the uses of the pillow.

[0014] In addition, the inner cover may be made of a stretchable fabric and the outer cover may be made of a less stretchable fabric, or both the inner and outer covers may be made of a stretchable fabric, or both the inner and outer covers may be made of a less stretchable fabric, and the appropriate choice may be made depending on the application.

[0015] Furthermore, with the double cover, the outer cover can be removed and washed when the pillow becomes soiled, ensuring the cleanliness of the pillow. [Brief explanation of the drawings]

[0017] The present invention will be described below with reference to the examples shown in the accompanying drawings. Figures 1 to 4 show a preferred embodiment of a pillow according to the present invention. In the drawings, when the most protruding part of the back of the head 31 of a user 30 is the occipital vertex 32, the pillow 10 has a three-dimensional shape having a occipital vertebra support portion 33 and a cervical vertebra support portion 35, and the cervical vertebra support portion 35 is configured to have a width that is at least the width of the cervical vertebrae of the user 30 in a supine position.

[0018] The occipital support portion 33 is adapted to support the temporal region 36 of the user's head around the occipital region 32 when the user 30 is lying on his / her back with the pillow 10 placed on the floor F. The occipital support portion 33 is made up of left and right portions, and is adapted to grip the temporal region 36 with an appropriate force by opening to the left and right depending on the size of the occipital region 31 of the user 30.

[0019] The cervical vertebrae support portion 35 is continuous with the occipital support portion 33 and is manufactured to a size of approximately 10 cm x 10 cm so as to be lower than the occipital support portion 33, and is capable of supporting the cervical vertebrae 34 of the user 30 in a supine position.

[0020] The pillow 10 is made of a stretchy material knitted with, for example, 70% cotton, 25% polyester, and 5% polyurethane, and contains spherical synthetic resin foam beads with an average particle size of 0.5 mm to 10 mm, preferably 0.5 mm to 2 mm. The pillow 10 may be made of a knitted fabric made of 100% cotton, or any other known fabric may be used.

[0021] Furthermore, although synthetic resin foam beads are embedded inside the pillow 10, it is also possible to embed molded synthetic resin beads, plastic pipes, cotton, polyurethane foam, polyethylene fiber, polyester fiber, a three-dimensional structure of entangled polyethylene fiber or polyester fiber, a three-dimensional structure of elastomer resin, a short cut pipe like a straw, or buckwheat husks.

[0022] When resting in a supine position, the back of the head 31 is lightly placed between the left and right posterior parietal support portions 33, and the cervical vertebrae 34 are placed on the cervical vertebrae support portion 35. Then, as shown in Figures 1 and 4, the left and right posterior parietal support portions 33 open appropriately to hold the temples 36 of the user with an appropriate amount of force, and the weight of the back of the head 32 against the cervical vertebrae 34 is received by the posterior parietal support portions 33 and distributed, so that no extra stress is applied to the cervical vertebrae 34, shoulders, neck, or back when sleeping in a supine position, allowing for comfortable sleeping.

[0023] 5 shows a second embodiment, in which the same reference numerals as in Figures 1 to 4 indicate the same or corresponding parts. In this example, a substantially circular recess is formed in the center of the rear parietal support portion 33, so that the rear parietal support portion 33 can support almost the entire periphery of the rear parietal 32.

[0024] 6 shows a third embodiment, in which the same reference numerals as in Figures 1 to 4 indicate the same or corresponding parts. In this example, a substantially triangular recess is formed in the center of the posterior parietal support part 33, and the posterior parietal support part 33 is designed to support the part of the periphery of the posterior parietal 32 on the side of the cervical vertebrae 34 and the temporal region 36.

[0025] 7 shows a fourth embodiment, in which the same reference numerals as in Figures 1 to 4 indicate the same or corresponding parts. In this example, a linear groove is formed in the center of the posterior parietal support part 33, and the part of the periphery of the posterior parietal 32 that is on the side of the temporal region 36 of the posterior parietal 32 is supported by the posterior parietal support part 33.

[0026] 8 shows a fifth embodiment, in which the same reference numerals as in Figures 1 to 4 indicate the same or corresponding parts. In this example, the central portion of the posterior parietal support part 33 is cut in a straight line, so that the portion of the periphery of the posterior parietal 32 on the side of the temporal region 36 of the posterior parietal 32 can be supported by the posterior parietal support part 33.

[0027] 9 shows a sixth embodiment, in which the same reference numerals as in Figures 1 to 4 indicate the same or corresponding parts. In this example, four small diameter circles are formed in the central portion of the posterior parietal support part 33, and by extending this central portion, almost the entire circumference of the posterior parietal 32 can be supported by the posterior parietal support part 33.

[0028] 1 to 4 indicate the same or corresponding parts. In this example, the central part of the posterior parietal support part 33 is cut in a radial straight line, so that the part of the periphery of the posterior parietal 32 on the side of the temporal region 36 of the posterior parietal 32 can be supported by the posterior parietal support part 33.

[0029] In addition, the pillow 10 of this example may be covered with an outer cover made of stretchy fabric, and if the pillow becomes soiled, the outer cover can be removed and washed to ensure the pillow remains clean.

[0030] In addition, although the rear parietal support portion is formed by cutting fabric in the above example, the rear parietal support portion may also be formed by overlapping two pieces of fabric, sewing the fabric to the outer shape of the rear parietal support portion, and inflating the periphery while preventing foam beads or the like from getting inside.
