Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pillow that accommodates movement of the head during tossing and turning.

Pillows can be used during sleep to assist in lying on one's back (supine or supine) in a relaxed state. However, if the height of the pillow is too high or too low, the cervical vertebrae will be burdened and it will be impossible to relax and sleep. Normally, the most preferable sleeping position in the supine position is considered to be to reproduce the upright posture on a futon, mattress, etc., and this sleeping position that reproduces the upright posture puts the most burden on the cervical spine. It is said to be difficult.

By the way, in recent years, even when the sleeping position changes from a supine position to a sideways position (recumbent position or lateral position) due to rolling over, the height of the head, that is, the height of the temporal region from the floor, is considered to be the optimum height. Pillows that can support the body have been gaining attention.

For example, in Patent Document 1, as shown in FIG. 7, in order to support the right temporal region or the left temporal region when lying down, an occipital region supporting part 31 in the supine position has an occipital region supporting part 31 that supports the occipital region in the supine position. A pillow 30 is proposed which is divided into three sections (blocks) with two temporal support sections 32, 33 which are formed thicker than the section 31. FIG. This three-part pillow 30 can always support the sides of the head at an optimum height even when the person rolls over from the supine position to the lateral position.

The occipital region support portion 31 and the two temporal region support portions 32 and 33 are separated by linear boundaries (boundary lines 34 and 35), and the neck side (shoulder side) of these three blocks are generally formed in a straight line. The pillow 30 is arranged (placed) on a floor surface such as a bed so that these sides 36, 37 and 38 are substantially parallel to the shoulder width direction in the supine position as shown in the figure.

It should be noted that not only the pillow 30 described above, but also a person who generally sleeps using a pillow, when turning over from a supine position to a sideways lying position as shown in FIG. The line L11) is said to take a "natural" posture in which the line L11) leans slightly forward with respect to the line L10 of the spine, and the forward tilt angle R4 of the head (neck) in this natural posture is usually about 5 to 15 degrees. It is said.

Japanese Patent No. 2873019

However, in the pillow divided into the three parts mentioned above, the boundary or dividing line between the occipital head support in the center and the temporal support on both sides of the pillow is the top of the head to the neck in the supine position. It is parallel to the imaginary body center line (see straight line L20 in FIG. 7) extending from the waist to the toes. Therefore, when the head (neck) is tilted forward by about 5 to 15 degrees by rolling over from the supine position to the side position, the whole pillow may be misunderstood as being misaligned from the proper position. In some cases, the head (temporal region) is positioned at the edge or edge of the temporal region support, making it feel unstable and disturbing a good night's sleep.

In particular, children who have a lot of body movement when tossing and turning may pull their chins and curl their bodies when sleeping on their side (recumbent position), or raise their chins and lie on their backs. In some cases, the head falls off from the support, and improvement is desired.

SUMMARY OF THE INVENTION An object of the present invention is to provide a pillow in which the temporal region is reliably supported by the temporal region support part even when the user rolls over from the supine position to the lateral position, and stable sleep is not disturbed. be.

The pillow of the present invention comprises an occipital support part that supports the occipital region,
a first temporal support portion arranged on one side of the occipital region support portion for supporting the right temporal region when lying on one's back from a supine position with the tip of the right shoulder as a support point;
a second temporal support part that is disposed on the other side of the occipital support part and supports the left temporal region when lying on one's back from a supine position with the left shoulder as a supporting point; A pillow on which the head of
In plan view, a first boundary line between the first temporal region support portion and the occipital region support portion and a second boundary line between the second temporal region support portion and the occipital region support portion are the occipital region support portion. and the first temporal support portion and the second temporal support portion are line-symmetrical with respect to the center line of the occipital region support portion perpendicular to the arrangement direction of the first temporal support portion and the second temporal support portion, and the first boundary line and the second boundary line is decreasing from one end to the other end of the center line, and
The occipital head support, the first side head support, and the second side head support each have a pillow block composed of a bag containing stuffing,
The pillow is a custom-made pillow,
The first temporal support portion has the first side positioned on the first boundary line and a third side continuous with the other end of the first side, and the second side supports the second side. The temporal support portion is continuous with the second side located on the second boundary line and the other end of the second side, and is line-symmetrical with the third side with respect to the center line. and have sides of
The distance in plan view between the midpoint of the third side and the midpoint of the fourth side is from the tip of the right shoulder to the tip of the left shoulder of the back half circumference of the outer circumference length of the shoulder circumference of the user. is the length obtained by multiplying the length of by 1.1 ,
the third side and the fourth side, wherein the distance between the third side and the fourth side increases from the one end to the other end of the center line; The third side and the fourth side form an angle of 7° or more and 25° or less with the arrangement direction .

Further, the pillow of the present invention is characterized in that the first boundary line and the second boundary line form an angle of 3° or more and 15° or less with the center line .

According to the pillow of the present invention, when turning over, such as when shifting from a supine position to a lying position, the boundary line provided in a slanted shape with respect to the center line of the occipital region support part as described above will move the head. Since it hits in the direction perpendicular to the direction of movement, there is no sense of incongruity that the barrier (step) hits the head obliquely when turning over. Therefore, the pillow of the present invention can suppress the occurrence of factors that cause light sleep.

In addition, among the pillows of the present invention, the two boundary lines are inclined at 3° or more and 15° or less with respect to the center line, so that it is easier to get over the boundary line when turning over. It has the effect of

On the other hand, among the pillows of the present invention, one side of one temporal region support portion and one side of the other temporal region support portion, which are continuous with one side of the occipital region support portion in plan view, are aligned with the center line. and the distance between the one side of the one temporal support and the one side of the other temporal support is from the one end of the center line toward the other end of the center line The large pillow keeps the distance between the shoulders and the pillow (temporal head support) short even when you roll over from your back to the side, stabilizing the side of your head resting on the temporal head support. easier. In addition, since the distance between the shoulders and the pillow is close, even if the shoulders are used as a fulcrum to roll over from the supine position, and the chin is pulled back to take a lying position that is close to a natural posture, the central occipital support part will not move. After rolling over, the temporal region of the head can be easily accommodated approximately in the center of the temporal region supporting portions located on both sides. Therefore, with the pillow of the present invention, the temporal region is reliably supported by the temporal region support portion even after rolling over, and stable sleep is not disturbed.

Furthermore, the pillow of the present invention is suitable for infants, children, etc., who have large body movements when tossing and turning. Even so, it is possible to reduce the possibility that the temporal region falls off from the temporal region support portion.

Further, in the pillow of the present invention, the one side of the one side of the head support and the one side of the other side of the side of the head are arranged in the occipital region support and the side of the side of the side of the head, respectively. If the angle is 7° or more and 25° or less with respect to the installation direction, the distance between the neck and the pillow in the recumbent posture after rolling over is closer, and the support of the temporal region by the temporal region support part is reduced. can be done with certainty.

Further, among the pillows of the present invention, the distance between the midpoint of the one side of the one side head support and the midpoint of the side of the other side head support is The length obtained by multiplying the shoulder width of the user by a predetermined value makes it easier for the temporal region of the head after rolling over to fit substantially in the center of the temporal region support portion. Therefore, in the pillow of the present invention, the temporal region is reliably supported by the temporal region support portion, and it is easy to maintain a restful sleep.

FIG. 2 is a diagram showing a sleeping position on a conventional three-compartment pillow;

FIG. 1 is a plan view showing the configuration of a pillow according to a first embodiment of the present invention, and FIG. 2 is a cross-sectional view taken along line A-A' of FIG. 3 is a diagram for explaining the relationship between a person and a pillow when lying down, and FIG. 4 is a diagram for explaining the relationship between a person and a pillow when lying on the back. Note that hatching in the cross-sectional view is omitted. In addition, it is assumed that the pillow in each figure is placed on the head side of the floor surface of a futon, bed, etc. in this state, and the left and right sides of the figure are the left side of the user. and the right side. The points indicated by P1 to P6 in the drawing are midpoints (midpoints in the length direction) of each side or each line segment.

As shown in FIG. 1, the pillow 10 of the present embodiment has a trapezoidal occipital support portion 1 and a substantially trapezoidal shape, which are symmetrical with respect to the center line L0 in the width direction of the pillow (horizontal direction in the drawing). , a left first temporal support 2 and a substantially trapezoidal, right second temporal support 3, the first temporal support 2 and the second temporal support 3 is connected to the occipital support 1 via boundary lines 4 and 5 . In addition, as shown in FIG. 3, the width direction center line L0 of the occipital region support portion 1 extends from the top of the head in the supine posture toward the neck-waist-toe direction when placed on a futon or bed. It coincides with the straight line L20, which is the center line of the virtual body.

The occipital region support 1 supports the occipital region in a supine position where a person lies on his/her back, and the first temporal region support 2 and the second temporal region support 3 are respectively illustrated in FIG. It supports the right and left sides of the head in a recumbent position where a person lies on their side. The position of the temporal region of the head (the height from the floor surface) in the recumbent position is based on the support points of the shoulder tips of the side peripheral surfaces of the left and right shoulders, so as shown in FIG. The thickness (height from the floor surface) of the first temporal support section 2 and the second temporal support section 3 is smaller than the thickness of the occipital support section 1 so that the temporal region can be supported at an optimum height. It's getting thicker.

The greatest features of the pillow 10 in this embodiment are, as shown in FIG. A pair of two boundary lines 4 and 5 dividing the occipital region support portion 3 and the occipital region support portion 3 are oriented perpendicular to the arrangement direction of the occipital region support portion 1 and the temporal region support portions 2 and 3, respectively. Boundary lines 4 and 5 approach each other with respect to the center line L0 in the width direction of the portion 1 from the top of the head (upward in the drawing), which is one end of the person in the supine position, to the neck direction (downward in the drawing), which is the other end. It is formed in an inclined shape (inclination angle R1). In the drawing, the inclination angle R1 is shown with respect to an auxiliary line (line L1 parallel to the center line L0) drawn adjacent to the boundary lines 4 and 5 in order to make the inclination angle of the boundary lines easier to see. ing.

In addition, in the pillow 10 of the present embodiment, the boundary lines 4 and 5 are formed in a slanted shape. Similarly, the neck side short side 8 of the substantially trapezoidal second temporal region support portion 3 is oriented parallel to the arrangement direction of the occipital region support portion 1 and the temporal region support portions 2 and 3, respectively. It is arranged so as to be inclined at an inclination angle R2 toward the neck or shoulder (the other end side) of the person in the supine position with respect to the continuous direction of the neck side short side 6 of the center trapezoidal occipital head support 1 in plan view. characterized in that To make it easier to see, the inclination angle R2 is also shown in FIG. It is displayed with respect to the straight line L2.

The structure of the pillow 10 will be described in detail. The occipital region support portion 1, the first temporal region support portion 2, and the second temporal region support portion 3 are each made of a pillow block made up of cotton bags. A padding forming the main body of the pillow is enclosed inside the pillow block. In this embodiment, the pillow 10 is formed by sewing each pillow block. The surface may be covered with cloth material.

As the stuffing inside the pillow block, for example, buckwheat, cypress chips, pipe, polyethylene beans, feathers, feathers, cotton cotton, polyester cotton, fiber balls and the like can be used. As the material for the cover, for example, cotton, silk, linen, wool, nylon, rayon, acrylic, polyester cloth, double raschel mesh cloth, or the like can be used.

Before joining (connecting) by sewing, each pillow block has an inverted trapezoidal shape with the parallel short side, which is usually the upper side or the upper base, facing downward, as shown in FIG. Parallel long sides are arranged on the sides. The oblique sides of the trapezoid on both sides in the width direction form a boundary line that connects the adjacent inverted trapezoidal pillow blocks. The right oblique side of the first temporal support portion 2 is joined by sewing, and the boundary line 5, which is the right oblique side, is joined to the left oblique side of the second temporal support portion 3 by sewing, and is integrated in the width direction. A pillow 10 is made.

Here, the boundary lines 4 and 5 formed by the above-described sewing are respectively aligned with the center line L0 in the width direction of the central occipital region support portion 1 from the top of the head (one end: upper side in the drawing) of the person in the supine position in the neck direction. The boundary lines 4 and 5 are formed in an inclined shape in which the boundary lines 4 and 5 approach each other toward (the other end: downward in the drawing). The inclination angle R1 is usually set to 3° or more and 15° or less, preferably 5° or more and 10° or less for a general-purpose adult product (pillow). As described above, in the drawing, in order to make the inclination angle of the boundary lines easier to see, the inclination angle R1 is the auxiliary line drawn at the position adjacent to the boundary lines 4 and 5 (parallel to the center line L0). It is shown relative to the line L1).

In addition, the inclination angle R1 of the boundary lines 4 and 5 (the other half line of the corner: the other side) with respect to the parallel line L1 (substitute line for the center line L0, one half line of the corner: one side) is These two sides (half lines) are defined as "corner sides", and midpoints P1 and P2 of boundary lines 4 and 5 are defined as "corner vertices". It should be noted that all subsequent measurements of inclination angles (including inclination angles R2 and R3 described later), unless otherwise noted, are one of the two sides forming an angle (boundary line or neck The midpoints P1 to P6 of the short side) are defined as "corner vertices", and the angle between these corner vertices is measured.

Further, the numerical range of the inclination angle R1 of the boundary lines 4 and 5 with respect to the width direction center line L0 (parallel line L1) indicates the range of specifications for general-purpose (ready-made) products, which will be described later. It does not limit the specifications of the one-of-a-kind item that is made to order according to the user's body shape and preferences. In addition, general-purpose products for children, who are said to sleep with their bodies curled up in many cases, are usually set to 3° or more and 25° or less, preferably 4° or more and 21° or less.

According to the above configuration, since the boundary lines 4 and 5 hit the direction perpendicular to the moving direction of the head when rolling over, there is no sense of incongruity that the head hits the barrier (step) obliquely when the user rolls over. . Therefore, this pillow 10 can smoothly roll over.

In any case, when the inclination angle R1 is less than the lower limit or exceeds the upper limit, the left and right first temporal support parts 2 and second temporal support parts 3 are The head (temporal region) cannot be supported stably, and there is a risk of disturbing a restful sleep.

In relation to the fact that the boundary lines 4 and 5 are formed in an inclined shape, the pillow 10 of the present embodiment has the first temporal support portion 2 and the second temporal region as shown in FIG. Opposite sides 12 and 13 of the head support portion 3 with respect to the boundary lines 4 and 5 are oriented perpendicular to the arrangement direction of the occipital head support portion 1 and the temporal head support portions 2 and 3, respectively. With respect to the center line L0 in the width direction, it is formed in an inclined shape (inclination angle R3) that approaches each other from the top of the head (upward in the drawing), which is one end of the person in the supine position, to the neck direction (downward in the drawing), which is the other end. It is The inclination angle R3 is set to be the same as the inclination angle R1 of the boundary line, or R1+20° or less, preferably R1+5° or more and R1+15° or less.

As with the inclination angle R1 of the boundary line, the inclination angle R3 is an auxiliary line (line L3 ). Also, as described above, the inclination angle R3 is measured at the midpoints P5 and P6 of the opposite sides 12 and 13. As shown in FIG.

According to the above configuration, since the opposite sides 12 and 13 are inclined at a predetermined angle, when lying down, the bent hands do not interfere with the pillow (see FIG. 7) and sleep is not disturbed as in the conventional product. It is possible to move the hand freely during sleep (see FIG. 3). Therefore, restful sleep is maintained.

On the other hand, the parallel short sides (neck-side short sides 7) of the first temporal region support portions 2 on both sides in the width direction located on the neck side (lower side in the drawing) of the pillow 10 and the parallel directions of the second temporal region support portions 3 The short sides (neck-side short sides 8) are line-symmetrical with respect to the center line L0 in the width direction of the central occipital head support portion 1, and as shown in FIG. , that is, the continuous direction ( It is arranged so as to be inclined at an inclination angle R2 in a direction toward the neck side (the other end side: downward in the figure) with respect to the straight line L2).

The inclination angle R2 of the neck-side short sides 7 and 8 is usually set to 7° or more and 25° or less, preferably 3° or more and 10° or less for a general-purpose adult product (pillow). In addition, the above-mentioned suitable angle range, like the angle of inclination R1, indicates the range of specifications for general-purpose (ready-made) products. It is not limited. Furthermore, general-purpose products for children, who are said to sleep with their bodies curled up, are usually set to 3° or more and 25° or less, preferably 5° or more and 20° or less.

As described above, the straight line L2 is a half straight line connecting the midpoint P3 of the short neck side 7 and the midpoint P4 of the short neck side 8 . Further, the inclination angle R2 is an angle with the midpoint P3 of the neck-side short side 7 or the midpoint P4 of the neck-side short side 8 as the "apex of the corner."

In any case, if the tilt angle R2 is a pillow with specifications below the lower limit or above the upper limit, after turning over, the head (temporal head) will be on the edge or edge of the temporal support parts 2 and 3. A restful sleep may be disturbed by feeling that the position is unstable, or by dropping the head from the temporal support parts 2 and 3 .

In addition, the shape of the lower side (neck side short sides 6, 7, 8) of the entire pillow 10 including the central neck side short side 6 is the same as the neck side of the left and right temporal region support portions when lying on one's back as shown in FIG. The short sides 7 and 8 spread left and right along the slope of the shoulder across the position of the person's neck (the neck side short side 6 of the occipital support part). It can also be said that it is a Chinese numeral) shape. These neck side short sides 6, 7, and 8 do not necessarily have to be straight lines, and may be curved, arc-shaped, or wavy, for example.

In addition, the shape of the entire pillow 10 including each parallel long side (parietal side long side) of the occipital region support portion 1, the first temporal region support portion 2, and the second temporal region support portion 3 is a circular ring with a width. A part of the ring, that is, a shape obtained by cutting a part of the ring in a fan shape, or a shape in which three or more polygons (trapezoids) are connected in an arc shape on the same circumference. The temporal support portion may be a curved surface including a polygon with a pentagon or more, a semicircle, a semiellipse, and the like. There are no restrictions on the shape of the temporal support part, but the size (width) that the entire head can be placed on is required.

According to the pillow 10 configured as described above, the distance between the shoulders and the pillow (temporal head support portion) is short, and the position of the head after rolling over is easily stabilized. That is, when turning over from a supine position to a side-lying position during sleep, as shown in FIG. may adopt a recumbent position close to Even in such a case, with the pillow 10 configured as described above, the side of the head after tossing and turning can be accommodated in a stable position in the center of the side of the head supporting part, It can be supported by this side head support. Therefore, with the pillow 10 of the present embodiment, even after rolling over, the temporal region is reliably supported by the temporal region support portion, and stable sleep is not disturbed.

Next, a case where the pillow 10 is not a general-purpose off-the-shelf product, but a made-to-order product (pillow 11) whose specifications can be changed according to the user's body type and preferences will be described.

The custom-made pillow 11 shown in FIG. can be set according to the body shape and preferences of a specific user (pillow owner). (shoulder tip) is added.

That is, the characteristics of the custom-made pillow 11 include the characteristic configuration of the pillow 10 described in FIGS. The distance (distance W1) between the midpoint P3 of the short side 7 and the midpoint P4 of the neck-side short side 8 of the second temporal support portion 3 is a predetermined value equal to the length W0 of the user's shoulder width. (hereinafter referred to as a "coefficient"; in this example, 1.1).

The user's shoulder width W0 can be measured using the following method. That is, first, a user is photographed using a 3D image photographing and recording device that measures a stereoscopic (three-dimensional) image and dimensions of each part of the body using an imaging means such as a camera, and stereoscopic image data of the body (body coordinate data). As for the user's posture during shooting, the standing posture is preferable because the standing posture is close to the ideal sleeping posture.

Next, from the recorded stereoscopic image data, it is possible to obtain the distance from tip to tip of the side circumferential surfaces of the left and right shoulders by calculation. Strictly speaking, the length W0 of the shoulder width of the user is preferably set to the value (W0) of the half circumference of the circumference of the shoulder circumference, considering the rotation of the body when turning over. Also, as a simple method of measuring W0, the distance between the user's shoulders (linear distance) is measured using a tape measure or the like, and the calculated value obtained by multiplying the measured value by the above-mentioned coefficient (for example, 1.1) is It may be used as the interval (distance W1) between the midpoint P3 and the midpoint P4.

As described above, if the specification takes into account the length W0 of the shoulder width of the user, even if the user rolls over from the supine position to the side lying position with the shoulder as the fulcrum, the side sleeping posture will be natural (see FIG. 3). ), and since the shoulders and the pillow are in close contact, the head and chin are less likely to protrude from the pillow.

In the above-described first embodiment, in order to clarify the effect of the characteristic configuration of the pillow of the present invention, a relatively simple pillow has been described as an example. It can also be applied to a pillow or the like having a complicated configuration in which the support style differs for each part.

For example, in the case of the pillow 20 of the second embodiment shown in FIGS. 5 and 6, the occipital region support 1, which is one block in the pillow 10 of the first embodiment, has the same function as the occipital region support 1. The occipital head support section 21, the cervical spine support section 29 arranged on the neck (shoulder) side of the occipital head support section 21, and the occipital head support section 21 arranged between the occipital head support section 21 and the first side head support section 2 on the left side. It is divided into four blocks consisting of a first inclined surface portion 22 and a second inclined surface portion 23 disposed between the occipital region support portion 21 and the second temporal region support portion 3 on the right side. Reference numerals 24 and 25 in the figure denote boundaries (inflection curves) between the plane and the slope.

When the pillow 20 of the second embodiment is viewed from the cross-sectional direction, as shown in FIG. 6(b), the occipital region support part 21 supports the floor height of the occipital region in the supine position as in the first embodiment. In addition to being thick, the cervical spine support part 29 is thick enough to support the neck (cervical spine) when lying on one's back. Further, as shown in FIG. 6(a), the left and right first temporal support parts 2 and second temporal support parts 3 correspond to the floor surface height of the head (temporal region) when lying down. The first slanted surface portion 22 and the second slanted surface portion are arranged between the occipital region support portion 21 and the first temporal region support portion 2 and the second temporal region support portion 3. 23 is an inclined surface connecting the upper surface of the occipital region supporting portion 21 and the upper surfaces of the temporal region supporting portions 2 and 3, respectively. Therefore, the step between the occipital region support portion 21 and the first temporal region support portion 2 and the second temporal region support portion 3 is reduced, and the pillow 20 can be used when turning over from the supine position to the lateral position. , tossing and turning smoothly.

In the second embodiment, the neck side short side 26 of the substantially trapezoidal occipital region support portion 21 (including the cervical spine support portion 29, the first inclined surface portion 22, and the second inclined surface portion 23) and the first temporal region Because the neck side short side 27 of the head support portion 2 and the neck side short side 28 of the second side head support portion 3 are formed in a curved line (arc shape), which is different from the linear shape of the first embodiment. , supposing that the tangents of these arcs represent the continuous direction of the neck short side 26 (straight line L2) and the continuous direction of the neck short side 27 and the neck short side 28, The angle (inclination angle R2) between these neck-side short sides is calculated.

In the pillow 20 of the second embodiment having the above configuration, the occipital region support portion 21 and the cervical spine support portion 29 located in the center of the pillow, and the first temporal region support portion 2 and the second lateral region connected to the left and right sides thereof A pair of two boundary lines 4 and 5 that divide the support portion 3 are respectively aligned with the width direction center line L0 of the occipital region support portion 21 from the top of the head (one end: upper side in the figure) to the neck of the person in the supine position. The boundary lines 4 and 5 are formed in an inclined shape in which the boundary lines 4 and 5 approach each other in the direction (the other end: downward in the figure), and the direction perpendicular to the arrangement direction of the occipital region support portion 21 and the temporal region support portions 2 and 3 The inclination angle R1 with respect to the center line L0 in the width direction is normally set to 3° or more and 15° or less, preferably 3° or more and 10° or less for general-purpose products for adults (pillows). In the drawing, the inclination angle R1 is shown with respect to an auxiliary line (line L1 parallel to the center line L0) drawn adjacent to the boundary lines 4 and 5 in order to make the inclination angle of the boundary lines easier to see. ing.

Further, similarly to the first embodiment, the (tangent to) the neck-side short side 27 of the first temporal support section 2 and the (tangent to) the neck-side short side 28 of the second temporal support section 3 are With respect to the continuous direction of the neck side short side 26 of the central cervical spine support 29 (the straight line L2 by the tangent line) in the direction parallel to the arrangement direction of the occipital region support 21 and the temporal region support 2, 3 , toward the neck or shoulders (the other end side) of a person in a supine position at an inclination angle R2, and this inclination angle R2 is usually 7° or more and 25° for general-purpose products for adults (pillows). Below, it is preferably set to 5° or more and 20° or less.

Furthermore, in the pillow 20 of this embodiment, as in the first embodiment, the opposite sides 12 and 13 of the boundary lines 4 and 5 are perpendicular to the arrangement direction of the occipital region support portion 21 and the temporal region support portions 2 and 3, respectively. With respect to the width direction center line L0 of the occipital region support part 21 in the opposite direction, from the top of the head (upward in the figure) that is one end side of the person in the supine position to the neck direction (downward in the figure) that is the other end side, they approach each other. It is formed in an inclined shape (inclination angle R3). The inclination angle R3 is set to be the same as the inclination angle R1 of the boundary line, or R1+20° or less, preferably R1+5° or more and R1+15° or less. In the drawing, the inclination angle R3 is shown relative to an auxiliary line (a parallel line L3 to the center line L0) drawn at positions adjacent to the opposite sides 12 and 13 for easy viewing of the inclination angle. The angle R3 is similarly measured at the midpoints P5 and P6 of the opposite sides 12 and 13, respectively.

With the above configuration, the pillow 20, as in the first embodiment, hits the boundary lines 4 and 5 perpendicularly to the moving direction of the head when turning over, so that the head hits the barrier (step) obliquely. I never feel uncomfortable. Therefore, it is possible to roll over smoothly. Furthermore, since the pillow 20 is provided with inclined surface portions 22 and 23 connecting the upper surfaces of the occipital region support portion 21 and the temporal region support portions 2 and 3, the step is further alleviated. This makes it easier to roll over from the supine position to the side-lying position.

In addition, the pillow 20 has a short distance between the shoulders and the pillow (temporal head supporting portion), so that the head is easily stabilized after tossing and turning. Even in a lying position close to a natural body with the chin pulled in, where R4 is about 5 to 15 degrees, the temporal region after rolling over can be kept in a stable position at the center of the temporal region support. Therefore, with the pillow 20 of this embodiment as well, after rolling over, the temporal region is reliably supported by the temporal region support portion, and a stable sleep is not disturbed.

In this embodiment, the cervical spine support 29 is provided only at one end of the occipital region support 21, but the first temporal region support may be provided as long as the temporal region does not feel uncomfortable in the lying position. It may be provided at one end of the portion 2 and the second temporal support portion 3 (shoulder side in lying position). An inclined surface portion may be provided between the cervical spine support portion 29 and the temporal support portions 2 and 3 .

In addition, in this embodiment, the pillow 20 can be integrally molded with a material such as urethane foam. 2. After the inclined surface portion 23 and the cervical vertebra support portion 29 are prepared as pillow blocks consisting of bags containing stuffing, each pillow block is sewn to prepare a pillow core material, and the surface of the pillow core material is covered with cloth. It can also be produced by covering with

In that case, as a pillow block corresponding to the first inclined surface portion 22 and the second inclined surface portion 23, an intermediate height between the occipital region support portion 21 and the first temporal region support portion 2 and the second temporal region support portion 3 is used. You may use a pillow block with

In addition, in the present embodiment, the occipital region support portion 21, the first temporal region support portion 2, the second temporal region support portion 3, the first inclined surface portion 22, the second inclined surface portion 23, and one end of the occipital region support portion 21 Including the cervical spine support 29 disposed on the side (shoulder side in recumbent position), an embodiment in which each pillow block of the cervical spine support 29 has a different height is illustrated, but each pillow block has the same height. Even if there is, it should be designed so that the height of the head is the optimum height in the sleeping posture.

In other words, even if the height of each pillow block is the same when not compressed (when the pillow is not in use), the difference in sinking amount (height difference) when compressed (when the pillow is in use) Compressive deformable elastic materials with different hardnesses may be used as the material of the pillow block so as to make a difference. By using an elastic material for the pillow block, the repulsive energy stored by compression when rolling over acts when the head is lifted, so that the head can be easily lifted and turned over even with a pillow having steps.

Furthermore, the pillow 20 of this embodiment can also be custom-made like the pillow 10 of the first embodiment. For example, as shown in FIG. 6, the distance ( A specification that takes into account the shoulder width W0 of a specific user by setting the distance W1) to the length corresponding to rolling over, which is obtained by multiplying the length W0 of the shoulder width of the user by a predetermined coefficient (1.1 in this example). can be As a result, even when the specific user rolls over from the supine position to the side-lying position with the shoulder as a fulcrum, the user can more easily maintain the natural side-lying posture, and the shoulders and the pillow are in close contact with each other. And the chin is less likely to protrude from the pillow, which is preferable.
