Description

cervical pillow

[0001] The present invention relates to a cervical pillow, and more particularly, to a cervical pillow that can provide comfortable sleep while maintaining the cervical curvature.

[0002] Pillows are typically used to support the head and neck while lying down, ensuring a comfortable sleep. Recently, a variety of functional pillows have emerged to improve sleep quality and promote proper sleeping posture. Among these are cervical pillows, which support the head and neck, creating a lordotic curve.

[0003] Cervical pillows support the neck, preventing neck muscle fatigue and reducing tension in the neck and shoulders. They are also known to relieve headaches and neck pain. They also dilate the trachea and airways, improving breathing. This is why many people use them. Most cervical pillows have a concave shape for the head and a convex shape for the neck.

[0004] In this way, the concave and convex parts of the pillow's upper surface, which are designed to support the user's head and neck, only function as a cervical pillow when the user is lying down in an upright position without moving. Since they interfere with the user's natural tossing and turning during sleep, they can also increase the user's tossing and turning. In addition, the part that supports the neck in conventional cervical pillows is designed to create a lordotic curve in the cervical spine, but this is excessively high, which can cause the user's chin to rise and the crown of the head to face the floor, making it difficult to breathe comfortably. In addition, since it is hard and supports the stiff occipital muscles, it can actually cause pain. In addition, users who lie down with their heads on the flat parts on either side of the concave parts that are designed to support the user's head while lying down in an upright position will inevitably experience cervical misalignment because the neck area will not be supported.

[0005] The present invention is intended to solve the above problems, and the purpose of the present invention is to provide a cervical pillow that allows the cervical spine of a user lying in an upright posture to form a forward curve while the structure of the pillow does not interfere with the natural tossing and turning that occurs during sleep, thereby providing a comfortable sleep.

[0006] In addition, the purpose is to provide a cervical pillow that can support the user's neck along with the user's head when lying in a side posture to align the cervical spine.

[0007] In order to achieve the above object, the cervical pillow of the present invention comprises: a pillow body including a normal posture support portion; and side posture support portions formed to extend in both directions from the normal posture support portion, and made of a material having elasticity and resilience; wherein the normal posture support portion is formed such that an upper surface thereof is flush with an upper surface of the side posture support portion, and an alignment-inducing groove is formed upwardly on a lower surface corresponding to an upper surface portion where the head and neck of a user lying in a normal posture are supported.

[0008] In addition, the alignment-inducing home may include a first alignment-inducing part that is turned off by the head of a user lying in an upright posture, and a second alignment-inducing part that is recessed to have a lower height than the first alignment-inducing part and is turned off by the neck of a user lying in an upright posture.

[0009] In addition, the first alignment guide unit may have a square pyramid shape, and the second alignment guide unit may have a left-right width at the bottom that is the same as the left-right width at the bottom of the first alignment guide unit, and an upper left-right width at the top that is larger than the upper left-right width of the first alignment guide unit.

[0010] In addition, the device may further include an off-adjustment pad having a plate shape that is lower in height than the first alignment induction unit and that can be provided within the first alignment induction unit.

[0011] In addition, the back side of the pillow body, which is located near the shoulder of the user lying down, has a convex curved shape toward the front so that the user's shoulder line is adjacent when viewed from a flat surface, and has a curved shape that protrudes toward the rear from the bottom to the top so that the top can wrap around the upper side of the shoulder.

[0012] According to the present invention, the alignment-inducing groove is pressed by the weight of the head and neck of a user lying in an upright posture, and a natural depression occurs on the upper surface of the upright posture support part. Therefore, even if the user tosses and turns while sleeping while maintaining an upright posture, the user's head and neck are stably supported, so that the user can sleep comfortably.

[0013] In addition, due to the difference in the degree of deflection of the first alignment guide and the second alignment guide, the neck can be supported and wrapped so that the cervical vertebrae are aligned, and the cervical vertebrae can be in a lordotic state. In addition, due to the rear structure of the pillow body (A), the user's entire head and neck can be stably supported not only when lying in a normal posture but also when lying in a lateral posture.

[0014] And, by adjusting the degree of off-time of the alignment guide home through the off-time control pad, it is possible to achieve an off-time suitable for the user.

[0024] The present invention proposes a cervical pillow comprising: a pillow body made of a material having elasticity and resilience, including a posture support portion; and side posture support portions extending in both directions from the posture support portion, so as to provide a comfortable sleep by allowing the cervical vertebrae of a user lying in an upright posture to form a lordotic curve while not interfering with the natural tossing and turning that occurs during sleep; wherein the posture support portion is formed such that an upper surface thereof is flush with an upper surface of the side posture support portion, and an alignment-inducing groove is formed upwardly on a lower surface corresponding to an upper surface portion where the head and neck of the user lying in an upright posture are supported.

[0025] The scope of the present invention is not limited to the embodiments described below, and various modifications may be made by a person having ordinary knowledge in the relevant technical field without departing from the technical spirit of the present invention.

[0026] Hereinafter, the cervical pillow of the present invention will be described in detail with reference to the attached drawings 1 to 9.

[0027]

[0028] The cervical pillow of the present invention includes a pillow body (A) on which a user lies down while sleeping or resting, as illustrated in FIGS. 1 to 4, and the pillow body (A) includes a posture support part (100) that supports the head and neck when the user lies down in a posture, and a side posture support part (200) that extends in both directions from the posture support part (200) to support the head and neck when the user lies down in a side posture.

[0029] This pillow body (A) is made of a material that has elasticity and resilience so that it can firmly support the user's head and neck while collapsing due to the weight of the user's head and neck, and can return to its original shape when the weight is removed. For example, the pillow body (A) can be made of a polyurethane material, but it is preferable to make it of a latex material, which has superior support, durability, breathability, and safety compared to memory foam.

[0030] Hereinafter, in explaining the present invention, the height direction of the pillow body (A) is referred to as the up-down direction, the length direction of the pillow body (A) is referred to as the lateral direction, and the width direction of the pillow body (A) is referred to as the front-back direction.

[0031] The upright posture support member (100), as illustrated in FIG. 1, is formed so that its upper surface is flush with the upper surface of the lateral posture support member (200), and an alignment-inducing groove (110) is formed upwardly on the lower surface corresponding to the upper surface portion where the head and neck of a user lying in an upright posture are supported, as illustrated in FIGS. 2 to 4. As illustrated in FIG. 5, when the user lies down in an upright posture and his or her head and neck are placed on the upright posture support member (100), the alignment-inducing groove (110) is pressed by the weight of the user's head and neck, and a natural depression occurs in the upper surface of the upright posture support member (100), so that a portion of the user's head and neck may be buried between the lateral posture support members (200) located on both sides.

[0032] In this way, as the upper surface of the posture support member (100) naturally sinks, a user whose head and neck are supported by the posture support member (100) can sleep comfortably, even if he or she tosses and turns while maintaining the posture, as the point at which the sinking is maximum only changes slightly as he or she tosses and turns, the user's head and neck are stably supported.

[0033] The alignment-inducing groove (110) may include a first alignment-inducing portion (111) that is depressed by the head of a user lying in an upright posture, as illustrated in FIGS. 2 to 4, and a second alignment-inducing portion (112) that is depressed by the neck of a user lying in an upright posture. The first alignment-inducing portion (111) is formed as the central portion of the bottom surface of the upright posture support portion (100) is recessed upward, and the second alignment-inducing portion (112) is formed as the rear end of the bottom surface of the upright posture support portion (110) is recessed upward. At this time, it is preferable that the second alignment-inducing portion (112) is recessed to have a lower height than the first alignment-inducing portion (111).

[0034] Accordingly, the posture support member (100) is formed so that the thickness from the upper surface to the upper end of the second alignment-inducing member (112) is thicker than the thickness from the upper surface to the upper end of the first alignment-inducing member (111), and as a result, the sagging of the upper surface portion of the posture support member (100) corresponding to the second alignment-inducing member (112) is relatively less than the sagging of the upper surface portion of the posture support member (100) corresponding to the first alignment-inducing member (111), so that the cervical spine of a user lying in an upright posture can form a forward curve.

[0035] For example, the first alignment guide member (111) may be formed into a cylindrical shape or a polygonal cylinder shape, but it is preferable to be formed into a horn shape to ensure natural sinking and stable support even when tossing and turning. Specifically, considering the shape of the user's head and the natural connection structure with the second alignment guide member (112), it is more preferable that the first alignment guide member (111) has a square horn shape as shown in FIGS. 2 to 4. At this time, it is preferable that the second alignment guide member (112) has a lower left-right width equal to the lower left-right width of the first alignment guide member (111) and an upper left-right width greater than the upper left-right width of the first alignment guide member (111), so as to easily wrap and support the neck so that the cervical vertebrae are aligned.

[0036] And in the present invention, the pillow body (A) can be configured to support the head and neck together not only when the user is lying in the upright posture but also when the user is lying in the side posture. To this end, the back side of the pillow body (A), which is located near the shoulder of the lying user, can have a convex curved shape toward the front so that the user's shoulder line is adjacent, as shown in FIG. 6 when viewed from the plan. That is, the side posture support part (200) can be formed so that the front-to-back width is longer than the front-to-back width of the upright posture support part (100), and so that the length increases as it gets farther away from the upright posture support part (100). This is to ensure that even when the user is lying in the side posture using the side posture support part (200), not only the user's side head but also the entire side of the neck is supported, as shown in FIG. 8, so that the cervical spine is aligned in a straight line.

[0037] In addition, the back of the pillow body (A) may be formed to have a curved shape that protrudes rearward from the bottom to the top, as illustrated in FIG. 7. Accordingly, as illustrated in FIGS. 6 and 7, when the user lies down in an upright posture, the upper back of the pillow body (A) wraps around the entire user's shoulder from above, thereby preventing the pillow body (A) from being twisted due to tossing and turning during sleep, and supporting the entire cervical spine, thereby more effectively maintaining the cervical lordosis. In addition, as illustrated in FIG. 8, when the user lies down in a side posture, the user's shoulder, which is positioned lower, is wrapped around the neck area due to the curved surface forming the back of the pillow body (A), thereby seamlessly filling the space between the user's chin and shoulder, thereby aligning the entire cervical spine.

[0038] Meanwhile, the present invention may further include a sleep adjustment pad (B) that allows for sleep adjustment, as each user has a different body shape, head shape, cervical spine condition, and preferred sleeping posture. The sleep adjustment pad (B), like the pillow body (A), may be made of a material having elasticity and resilience, and as illustrated in Fig. 9, may be formed in a plate shape that is lower in height than the first alignment guide part (111) and may be provided within the first alignment guide part (111). This sleep adjustment pad (B) may be detachably attached to the pillow body (A), and may be configured such that a plurality of pads can be detachably attached to each other.

[0039] For example, the off-adjustment pad (B) may be provided in multiple pieces by dividing the square pyramid having the same size and shape as the first alignment guide (111) into a predetermined number of pieces at a predetermined height. At this time, the remaining off-adjustment pads (B) except for the off-adjustment pad (B) that can be positioned at the lowest side in the first alignment guide (111) may be provided with Velcro on the upper and lower surfaces, and the off-adjustment pad (B) that can be positioned at the lowest side in the first alignment guide (111) may be provided with Velcro on the upper surface. In addition, the upper end of the first alignment guide (111) may be provided with Velcro for attachment and detachment with the off-adjustment pad (B) that can be positioned at the highest side.

[0040] Accordingly, the user can adjust the number of the off-adjustment pads (B) attached within the first alignment induction unit (111) to allow the user to sleep comfortably while naturally causing the cervical spine to be aligned.
