Description

Pillow with ergonomic structure {Ergonomic pillow}

The present invention relates to a pillow having an ergonomic structure, and more particularly, to a pillow capable of correcting a comfortable sleeping posture by supporting the upper part of the back from the head to the body curve according to the lordosis of the cervical spine and the kyphosis of the thoracic spine. it's about

Recently, as the importance of sleep has been highlighted, interest in functional pillows for a good night's sleep is increasing.

In general, pillows are used only for supporting only the head during sleep, and are used by filling the inside of the pillow with cushioning materials such as cotton and foam so as not to press the head.

Such a conventional pillow rests or sleeps while supporting the back of the head, that is, the back of the head, in a lying state. At this time, the head is bent forward and the C-shaped cervical vertebrae are pressed in the reverse direction, resulting in neck flexibility due to stiffness of the back neck muscles. On the other hand, it is not able to absorb the load of the head and is transmitted to the spine, resulting in a disc disease.

Among the vertebrae, the cervical vertebrae located in the neck form a lordosis that forms a C-curve convexly toward the front, while the thoracic vertebrae form a kyphosis that is convexly curved backwards, opposite to the cervical vertebrae. In this way, the S-shaped line of the spine can alleviate the gravitational force applied to the body.

Accordingly, various pillows for supporting the cervical spine capable of maintaining the C-shaped curve of the cervical spine by supporting the cervical spine higher than the head at night have been developed. This type of pillow proposes a pillow shape with a curved structure similar to the curved shape of the cervical vertebrae. In this case, the heart rate becomes unnatural, and there is a risk that cardiovascular function may be impaired. In addition, conventional pillows for supporting the cervical vertebrae do not provide a function of towing/supporting the user's shoulders and the connection between the cervical vertebrae and the thoracic vertebrae that are spaced apart from the ground (or bed) during sleep.

In addition, in describing the present invention, if it is determined that a detailed description of related known technologies may unnecessarily obscure the subject matter of the present invention, the detailed description will be omitted. In this specification, terms such as first and second are used to distinguish one element from another element, and elements are not limited by the terms. In the accompanying drawings, some components are exaggerated, omitted, or schematically illustrated, and the size of each component does not entirely reflect the actual size.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The present invention is ergonomically configured so that a person can comfortably sleep in an upright posture while maintaining lordosis of the cervical spine and kyphosis of the thoracic spine. Specifically, the present invention is formed to stably support not only the head, neck, upper back, but also the shoulder during a sound sleep.

As is widely known, the body consists of 7 cervical vertebrae, 12 thoracic vertebrae, 5 lumbar vertebrae, and 5 sacral vertebrae, as shown in FIG. It can be supported by using the spine composed of the coccyx (consisting of four coccyx vertebrae, but fused into one as an adult) as the central skeleton.

The spine is made up of 26 bones, supporting the head upward and connecting with the pelvis downward. It not only maintains a stable posture by normal sagittal curvature of the spine, but also effectively absorbs the load applied to the spine and relieves tension and strain on soft tissues. It can be prevented. Among the vertebrae, the cervical vertebrae located in the neck form a lordosis that forms a C-curve convexly toward the front, while the thoracic vertebrae form a kyphosis that is convexly curved backwards, opposite to the cervical vertebrae.

Accordingly, a pillow having an ergonomic structure (hereinafter referred to as a pillow) according to a preferred embodiment of the present invention proposes a pillow having a curved shape corresponding to a body shape in consideration of a body structure such as a head or neck.

2 to 3, the pillow according to a preferred embodiment of the present invention includes a base portion 110, a neck support portion 120 for supporting the user's cervical spine, and a head seating portion 130 for supporting the back of the user's head. ), and a shoulder/back mounting unit 140 capable of supporting a part of the user's back. Furthermore, the present invention is configured to support both shoulder blades with the shoulder/back mounting portion 140 together with the upper thoracic vertebrae spaced apart from the ground (or floor) of the sleeping place by the lordosis structure of the thoracic vertebrae.

In other words, the pillow according to a preferred embodiment of the present invention has the head seating portion 130 and the neck on the upper surface of the base along the longitudinal direction (ie, longitudinal direction) of the pillow so that the head, shoulders and back can be comfortably supported. The supporting portion 120 and the shoulder/back mounting portion 140 may be arranged.

The base part 110 is a component member formed in a size and shape capable of supporting and holding the previously described neck support part 120, the head mounting part 130, and the shoulder/back mounting part 140. It may be formed in a rectangular parallelepiped shape having a supportable horizontal length (W), a supportable vertical length (L) from the back of the head to the upper thoracic vertebrae of the user, and a predetermined height (H). For example, the base portion may be formed with a horizontal length (W) of 49 cm to 57 cm, a vertical length (L) of 28.6 cm to 31.2 cm, and a height (H) of 1.5 cm to 2.5 cm.

Here, the horizontal length (W) of the base part 110 has a range of 49 cm to 57 cm to sufficiently support the average torso width (45.5 cm, refer to the National Standard Posture Survey Report (1997)) of Korean adult males. . In addition, the vertical length (L) of the base portion 110 has a range of 28.6 cm to 31.2 cm to accommodate the head seating portion, the neck support portion, and the shoulder/back portion to be arranged on the base portion. In particular, the base portion is to have a height H in the range of 1.5 cm to 2.5 cm. When the user lies on the pillow, the upper thoracic vertebrae adjacent to the cervical vertebrae are inevitably separated from the ground for kyphosis of the thoracic vertebrae. The degree of deflection due to kyphosis of the thoracic spine can be compensated. That is, without considering the kyphosis curvature of the thoracic vertebrae, the shoulder and back parts spaced apart from the ground can be supported as shown in FIG. 5 .

In addition, one side edge of the base portion is positioned in the width direction (i.e., horizontal direction) of the pillow by the separation gap provided between the shoulder/back of the user lying on the pillow in supine position (upright lying position) and the ground through the height H. An air flow path can be secured, and shoulder jamming can be minimized by stimulating the area from the shoulder to the back with the upper edge of one side edge.

As shown, the base 110 has a flat lower surface so that it can be placed horizontally on the ground in a sleeping place (eg, a bed, a blanket, etc.). Of course, the upper surface of the base part is also formed flat, so that the bottom surface of the neck support part 120, the bottom surface of the head seating part 130, and the bottom surface of the shoulder/back mounting part 140 are on the same plane (or the same level). It can be placed so that it lies on .

Thus, the present invention arranges the head seating part 130 at a second height (H ₂ ) lower than the first height (H ₁ ) of the neck support part 120, and at the same time lower than the first height of the neck support part, while lowering the thoracic spine The shoulder/back mounting portion 140 may be formed with a downward slope so as to maintain kyphosis. A detailed description of this will be described below.

As is well known to those skilled in the art, the cervical vertebrae located in the neck induce a normal person's cervical lordosis angle to about 35° so as to maintain a C-shaped curve toward the front. The term cervical lordosis refers to the degree of convex curvature of the cervical vertebrae toward the front. It is an angle consisting of an imaginary extension line extending from the center of cervical vertebrae #1 in the direction of formation and an imaginary extension line extending from the center of #7 cervical vertebrae in the direction of formation. can be measured If the user sleeps in the supine position without a pillow, the cervical vertebrae are subjected to a downward load, and neck muscles and shoulder muscles are inevitably stiff to support it.

Accordingly, the present invention provides a pillow capable of inducing lordosis of the cervical vertebrae, so that the cervical vertebrae can be correctly aligned and a comfortable sleeping posture can be taken.

As shown, the neck support part 120 is disposed in the center of the upper surface of the base part 110 and is convex upward to maintain the C-curve of the cervical vertebrae. Specifically, the neck support portion 120 may have a first upper surface 121 formed in a semicircular cross-sectional shape perpendicular to the vertical direction and extend in a dome structure in the horizontal direction of the pillow.

Preferably, the neck support part 120 may define a first height H ₁ between the uppermost end of the first upper surface 121 and the upper surface of the base part 110 in the range of 4.3 cm to 4.7 cm. The present invention supports the neck higher than the head of a user lying down on a pillow and supports the head relatively low, so that the cervical spine can be naturally maintained in a C-shaped curve.

In addition, the neck support part 120 of the present invention is a predetermined length corresponding to the length of the cervical vertebrae that can support from cervical vertebrae 1 to 7, more preferably from cervical vertebrae 1 to 6 along the C-shaped curve of the cervical vertebrae. has a vertical length of In other words, the first vertical length (L ₁ ) of the neck support part 120 is 16.2 cm to 17.4 obtained by orthogonal projection of cervical vertebrae No. 1 to No. 6 forming the lordosis of the C-curve on a plane. It has a range of cm.

As shown in FIG. 1, a normal spine forms lordosis in the cervical vertebrae while forming kyphosis in the thoracic vertebrae when viewed from the side, as shown in FIG. The curvature of the spine and the curvature of the thoracic spine are different. Therefore, the present invention can align the cervical vertebrae in a C-curve by supporting the first cervical vertebrae to the sixth cervical vertebrae using the neck support.

The pillow according to a preferred embodiment of the present invention arranges the head seating part 130 on the other side of the neck support part 120 on the upper surface of the base part 110. The head seating portion 130 has a second upper surface 131 and is formed long in the horizontal direction of the pillow. Preferably, the present invention, since the height of the head seating portion 130 is located relatively lower than the neck support portion 120, by slightly tilting the head of the user lying down on a pillow and positioning the head above the shoulder, the cervical spine It can induce lordosis and is ergonomically designed to disperse and reduce body pressure applied to the head and cervical spine so that you can have a comfortable sleep.

As shown in FIG. 5, the head seating part 130 may be deployed to a second vertical length L ₂ to stimulate the external occipital protuberance of the user in a lying state, and the second vertical length may range from 1.6 cm to 1.6 cm. Let it have a range of 2.2 cm. As is widely known to those skilled in the art, the external occipital prominence is a part to which the trapezius muscle is attached, and when the tension of the trapezius muscle increases, it causes headache, neck, and shoulder pain. Accordingly, the present invention can expand the head seating portion 130 to a second vertical length so as to support the head by dispersing the pressure while stimulating the external occipital ridge with the upper edge of the other edge of the head seating portion.

In addition, when the user's neck is tilted back, the height from the upper surface of the base part 110 to the back of the head so that the back of the head is located below the cervical vertebrae, that is, the second height between the second upper surface 131 and the upper surface of the base part 110 (H ₂ ) is designed to be smaller than the first height of the neck support 120. If the second height of the head resting unit 130 is very low, the user lying down on a pillow has no choice but to take an uncomfortable sleeping posture with his or her head bent. This causes the neck to be bent back excessively, and as a result, not only a lot of strain is transmitted to the neck, but also has a problem of causing spinal disease.

According to the present invention, the second height H 2 of the head seating part 130 is relatively lower than the neck support part 120 so as to support the user's head while maintaining an appropriate height, by defining the second height H ₂ in the range of 2.5 cm to 2.7 cm. , positioning the head slightly above the shoulders (or torso) can provide an optimal sleeping posture. In a normal spine, the second height H 2 can be calculated by Equation 1 below using the angle between the ground and the head (β; see FIG. ₁ ) as a parameter based on the third thoracic vertebrae in a lying state.

[Equation 1]

The first height (H ₂ ) = vertical length of the pillow (L) × tan (β)

Here, the angle (β = 5°) is an angle composed of the ground (horizontal reference line) extending from the posterior surface of thoracic vertebrae 3 (e.g., the spinous process of thoracic vertebrae 3) and an imaginary extension line extending from the posterior surface of thoracic vertebrae 3 to the occipital region ( see Figure 1).

According to Equation 1, the head seating part 130 has a second height H ₂ of approximately 2.5 cm to 2.7 cm.

In addition, the present invention provides a shoulder/back mounting unit 140 on one side of the neck support unit 120 on the opposite side of the head seating unit 130 based on the neck support unit 120, that is, on the upper surface of the base unit 110. It is configured to support the upper part of the user's shoulder and back by arranging.

As shown, the shoulder/back mounting portion 140 is formed on one side of the neck support portion 120 to gently incline downward toward one edge of the base portion 110 to induce kyphotic curvature of the thoracic vertebrae. Specifically, the shoulder/back mounting portion 140 has a third upper surface 141 inclined downward and is formed long in the horizontal direction of the pillow.

Preferably, the shoulder/back mounting portion is generally formed in a right triangle cross-sectional shape perpendicular to the vertical direction so as to support the upper thoracic vertebrae adjacent to the cervical vertebrae and at the same time support the scapula. For reference, it _is known that the thickness of each vertebrae is approximately 2.7 cm to 2.9 cm. It can be defined in the range of 10.8 cm to 11.6 cm. In the present invention, the third height (H ₃ ) of the shoulder/back mounting part 140 coupled to the boundary of the neck support part 120 is the third vertical length (L ₃ ) and the inclination angle of the third upper surface 141 ( It can be calculated by Equation 2 below using θ') as a parameter.

[Equation 2]

Third height (H ₃ ) = Third vertical length (L ₃ ) × tan(θ')

Here, the inclination angle θ' is the ground (horizontal reference line) extending from the posterior surface of thoracic vertebrae 3 (eg, spinous process of thoracic vertebrae 3) and the posterior surface of cervical vertebra 3 from the posterior surface of thoracic vertebrae 3 (eg, spinous process of cervical vertebrae 3). It is an angle (θ = 15 °, see FIG. 1) consisting of an imaginary extension line extended to .

According to Equation 2, the shoulder/back mounting portion 140 has a third height H ₃ of 2.9 cm to 3.1 cm. For reference, the third height (H ₃ ) of the shoulder/back mounting portion 140 connected to the neck support portion 120 is lower than the uppermost end of the neck support portion and is higher than the second height H ₂ of the head seating portion 130 It can be positioned high, so that it can support the 7th cervical vertebrae, which is the inflection point of the curve according to the lordosis of the cervical spine and the kyphosis of the thoracic spine.

Based on the above-mentioned inclination angle θ', the shoulder/back mounting part 140 may provide an oblique length L ₃ 'in the range of 11.2 cm to 12 cm according to a cosine definition.

As shown, the pillow of the present invention, especially the shoulder/back portion 140, has the same size as the horizontal length (W) of the base portion 110 so as to sufficiently support the user's torso width, so that the body during sleep By preventing the twisting and tossing of the bed, the supine position can be maintained, and the change to an uncomfortable sleeping position such as the side lying position can be prevented. As a result, it is possible to support the user's cervical vertebrae together with the upper thoracic vertebrae together with the scapula, providing stabilization of the cervical vertebrae, thoracic vertebrae, and scapulae.

In addition, the pillow according to a preferred embodiment of the present invention may be a single member integrally formed with the base portion 110, the neck support portion 120, the head seating portion 130, and the shoulder/back portion 140, , It is not limited to this, and a neck support part, a head seating part, or a shoulder/back mounting part may be selectively attached or detached on the base part.

In addition, the pillow may be formed of various materials such as memory foam, latex, urethane, sponge, and styrofoam, and may utilize an elastically deformable material as needed. Of course, the pillow may be used by filling the outer shell with a soft material such as natural cotton or synthetic fiber.

Optionally, the pillow according to the preferred embodiment of the present invention may include a non-slip member 150 on the lower surface of the base portion 110 as shown in FIG. 4 . Here, the non-slip member 150 has a configuration capable of preventing the pillow from slipping on the ground of a sleeping place, and may be made of a pad made of rubber or silicon. Not limited to this, the non-slip member may also be composed of Velcro (velcro, also known as Velcro). For example, when a female Velcro is installed on the lower surface of a pillow, a male Velcro may be installed on a duvet or bed corresponding to this.

A pillow having an ergonomic structure according to another embodiment of the present invention is shown in FIGS. 6 and 7, and since it has a very similar structure except for the shape of the upper surface of the pillow, similar or similar to help a clear understanding of the present invention. A description of the same configuration will be omitted here.

As shown, the pillow according to another embodiment of the present invention forms a plurality of grooves 160 over the entire upper surface of the pillow. In other words, the pillow arranges a plurality of grooves 160 formed in the horizontal direction on its upper surface at predetermined intervals in the longitudinal direction of the pillow, and the plurality of grooves 160 are the first upper surface of the neck support 120 ( 121), the second upper surface 131 of the head mounting part 130, and the third upper surface 141 of the shoulder/back mounting part 140 are spaced apart from each other at a predetermined interval.

A pillow according to another embodiment of the present invention is characterized in that a plurality of grooves 160 are formed in the horizontal direction of the pillow as described above. As is well known to those skilled in the art, the skeletal muscles around the neck/shoulder have a transverse pattern and are therefore voluntary muscles called striated muscles. A plurality of grooves are formed in the same direction as the striated muscle to reduce discomfort to the skeletal muscle during sleep and prevent slipping of the skeletal muscle so as not to interfere with sleep. In addition, the plurality of grooves may be used as an air flow path to ensure air circulation at a contact boundary between the upper surface of the pillow and a part of the user's body.

Optionally, the plurality of grooves 160 may be spaced apart at regular intervals of 1.5 cm, and are arranged in a concave-convex pattern at positions corresponding to the occipital bone, cervical vertebrae, thoracic vertebrae, and scapula, so that the user's head, neck, Stimulate the shoulder/back to induce myofascial relaxation. In addition, each groove 160 has a depth of 0.5 cm and a width of 1 cm and is recessed to a predetermined depth on the upper surface of the pillow.

As described above, the ergonomically structured pillow according to the present invention is a sleeping product designed widely in the horizontal direction to stably support both shoulders and upper back of the user who are spaced apart from the ground while securely supporting the head and neck. .

When lying down on such a wide pillow, the scapula of the shoulder area is bent forward, which may cause tension in the shoulder and trapezius muscles. In order to solve this problem, a pillow according to another embodiment of the present invention is proposed through FIGS. 8 and 9.

Therefore, the pillow according to another embodiment of the present invention has a hollow inner space 171 located inside adjacent to both sides of the shoulder and back portion corresponding to the shoulder blade, and an incision line 172 communicating with the inner space. ) is provided. The hollow inner space 171 may be provided symmetrically in the horizontal direction of the pillow in an inverted triangle shape corresponding to the shoulder blade. In addition, the incision line 172 may be incised on both side surfaces 142 defining the shoulder/back portion 140 of the pillow, as shown. The incision line 172 is formed in a long and narrow shape to allow air to flow in and out between the external environment and the internal space 171 .

Therefore, in the present invention, a part of the third upper surface 141 in contact with the two shoulder blades that are deployed laterally based on the thoracic vertebrae in the supine position is curved and recessed so that the third upper surface of the shoulder/back mounting portion is formed on the shoulder of the user. It is closely adhered to and supported according to the shape. In other words, when the third upper surface of the shoulder/back portion is pressed with the shoulder at bedtime, the air filled in the hollow internal space 171 flows out to the external environment through the incision line 172 and the internal space 171 ) contracts, which in turn helps the scapula to roll toward the ground. Through the structure of this pillow, a user lying down on the pillow according to the present invention can fix the shoulder blades and thoracic vertebrae in place during sleep to distribute the load on the shoulders, and as a result, expand the ribcage through stabilization of the cervical, thoracic and scapular vertebrae. This can ensure good sleep breathing.

The present invention has been described in detail through the examples, but this is for explaining the present invention in detail, the pillow of the ergonomic structure according to the present invention is not limited thereto, and within the technical spirit of the present invention, conventional It will be said that it is clear that the modification or improvement is possible by those who have knowledge.
