DETAILED DESCRIPTION

[0027] In the present disclosure, proposed is a cervical pillow that allows the user's cervical spine to have a lordotic curve while lying in a supine position, while ensuring comfortable sleep as the structure of the pillow does not interfere with the natural tossing and turning that occurs during sleep. To this end, the cervical pillow includes a pillow body consisting of: a supine posture support part; and a side-lying posture support part that extends in each direction from the supine posture support part, and made of a material with elasticity and resilience, wherein the supine posture support part is formed such that the upper surface thereof is flush with the upper surface of the side-lying posture support part, and has an alignment guide groove recessed upward on the bottom surface corresponding to the upper surface part where the head and neck of a user lying in the supine position are supported.

[0028] The scope of the present disclosure is not limited to the embodiments described below, and various modifications may be made by those skilled in the art without departing from the technical gist of the present disclosure.

[0029] Hereinafter, a cervical pillow of the present disclosure will be described in detail with reference to the attached FIGS. 1 to 9B.

[0030] As shown in FIGS. 1 to 4, the cervical pillow of the present disclosure includes a pillow body A on which a user lies while sleeping or resting, and the pillow body A consists of a supine posture support part 100 that supports the head and neck of a user when the user lies in a supine position; and a side-lying posture support part 200 that extends in each direction from the supine posture support part 100 to support the head and neck when the user is in a side lying position.

[0031] The pillow body A is made of a material with elasticity and resilience, so that a depression occurs due to the load of the user's head and neck, and the user's head and neck are firmly supported and may return to the original state thereof when the load is removed. As an example, the pillow body A may be made of polyurethane material, but is preferably made of latex material, which is more supportive and offers superior durability, breathability, and safety compared to memory foam.

[0032] Hereinafter, in describing the present disclosure, the height direction of the pillow body A is referred to as the vertical 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 (front-rear) direction.

[0033] The supine posture support part 100 is formed such that the upper surface thereof is flush with the upper surface of the side-lying posture support part 200 as shown in FIG. 1, and has an alignment guide groove 110 recessed upward on the bottom surface corresponding to the upper surface part where the head and neck of a user lying in the supine position are supported as shown in FIGS. 2 to 4. As shown in FIGS. 5A and 5B, when the user lies in the supine position and the head and neck of the user are placed on the supine posture support part 100, due to the load of the user's head and neck, the alignment guide groove 110 is pressed and the upper surface of the supine posture support part 100 is naturally depressed, causing part of the user's head and neck buried between the side-lying posture support parts 200 respectively located on opposite sides of the supine posture support part 100.

[0034] In this way, as the upper surface of the supine posture support part 100 is naturally depressed, even if the user whose head and neck are supported by the supine posture support part 100 tosses and turns during sleeping while maintaining the supine posture, only the most depressed point in the supine posture support part 100 changes slightly as the user tosses and turns, the user's 30 head and neck are stably supported, and thus the user may sleep comfortably.

[0035] As shown in FIGS. 2 to 4, the alignment guide groove 110 may include: a first alignment guide part 111 configured to be depressed by the head of the user lying in the supine position; and a second alignment guide part 112 configured to be depressed by the neck of the user lying in the supine position. The first alignment guide part 111 is formed as the central portion of the bottom of the supine posture support part 100 is recessed upward, and the second alignment guide part 112 is formed as the rear end of the bottom of the supine posture support part 100 is recessed upward. At this time, it is preferable that the second alignment guide part 112 is recessed to have a lower height than the first alignment guide part 111.

[0036] Accordingly, the supine posture support part 100 is formed such that the thickness from the upper surface to the top of the second alignment guide part 112 is greater than the thickness from the upper surface to the top of the first alignment guide part 111. Due to this, the degree of depression of the upper surface of the supine posture support part 100 corresponding to the second alignment guide part 112 is relatively less than the degree of depression of the upper surface of the supine posture support part 100 corresponding to the first alignment guide part 111, and thus the cervical spine of the user lying in the supine posture may have a lordotic curve.

[0037] As an example, the first alignment guide part 111 may be formed in a cylindrical or polygonal cylinder shape, but is preferably recessed to form a cone shape to promote natural depression and provide stable support even when the user tosses and turns. To be specific, when considering the shape of the user's head and a structure that facilitates natural connection with the second alignment guide part 112, it is more preferable for the first alignment guide part 111 to be in the shape of a square horn as shown in FIGS. 2 to 4. At this time, it is preferable that the second alignment guide part 112 has a left-right width of the bottom that is the same as the left-right width of the bottom of the first alignment guide part 111, and a left-right width of the top that is larger than the left-right width of the top of the first alignment guide part 111, so as to easily fit around and support the neck so that the cervical spine is aligned.

[0038] In addition, the pillow body A of the present disclosure may be configured to support both the head and neck not only when the user lies supine but also when the user lies sideways. To this end, the back side of the pillow body A located near the shoulder of the lying user may form a convex curve toward the front side so that the user's shoulder line is adjacent as shown in FIG. 6 when viewed from top. That is, the side-lying posture support part 200 may be formed to have a front-back width longer than the front-back width of the supine posture support part 100, and may be formed to become longer as the distance from the supine posture support part 100 increases. This is to ensure that not only the temporal region of the side of the user's head but also the entire side of the neck is supported so that the cervical spine is aligned even if the user lies in the side lying posture using the side-lying posture support part 200 as shown in FIG. 8.

[0039] Additionally, the back side of the pillow body A may form a curved surface that protrudes backward from the bottom to the top, as shown in FIG. 7. Accordingly, as shown in FIGS. 6 and 7, when the user lies in the supine position, the upper end of the back side of the pillow body A cradles the entire shoulder of the user from the upper side, thereby inhibiting the pillow body A from being twisted due to tossing and turning of the user during sleep, and helping to maintain the lordotic curve of the cervical spine more effectively. In addition, as shown in FIG. 8, when the user lies in the side lying position, the user's shoulder, which is located below, is cradled around the neck due to the curved surface that forms the back side of the pillow body A, and the space between the user's chin and shoulder is tightly filled by the pillow, so that the entire cervical spine may be aligned.

[0040] Meanwhile, since each user has different body type, head shape, cervical spine condition, and preferred sleeping position, the present disclosure may further include a depression control pad B configured to control depression. The depression control pad B, like the pillow body A, may be made of a material with elasticity and resilience, and as shown in FIGS. 9A and 9B, may have a plate shape with a height lower than that of the first alignment guide part 111 and may be provided within the first alignment guide part 111. The depression control pad B may be detachable from the pillow body A, and may be configured as a plurality of the pads, with the pads being detachable from each other.

[0041] As an example, the depression control pad B may be provided in a plural number by dividing a square horn having the same size and shape as the first alignment guide part 111 into pieces at every predetermined height. At this time, except for the depression control pad B, which may be located at the lowermost side of the first alignment guide part 111, the remaining depression control pads B may be provided with Velcro on the upper and lower surfaces thereof, and the depression control pad B, which may be located at the lowermost side of the first alignment guide part 111, may be provided with Velcro on the upper surface thereof. In addition, at the top of the first alignment guide part 111, Velcro may be provided for attachment to and detachment from the depression control pad B, which may be located at the uppermost side.

[0042] Therefore, the user is able to adjust the number of depression control pads B attached within the first alignment guide part 111 to produce an appropriate level of depression to ensure comfortable sleep and alignment of the cervical spine.
