Description

headrest cushion

[0001] The present invention relates to a headrest cushion, and more particularly, to a headrest cushion that can relax the neck while pulling the chin, thereby achieving a posture correction effect.

[0002] Modern people who frequently use smartphones or computers tend to lower their heads and stretch their necks forward. This posture causes turtle neck syndrome, which stretches the muscles and ligaments of the neck and shoulders, causing pain, as well as round shoulders, which can cause degenerative diseases such as shoulder impingement syndrome and rotator cuff tears.

[0003] Forward head posture and rounded shoulders can cause stiffness in the shoulders and back, headaches, and numbness in the arms. They can also reduce work and learning efficiency, lead to fatigue, and, in rare cases, even cause incoordination and dizziness. Furthermore, those with forward head posture and rounded shoulders are more likely to develop scoliosis and pelvic distortion, leading to imbalances throughout the body.

[0004] To correct this turtle neck and rounded shoulders, devices like neck traction devices and neck stretchers are used. However, neck traction devices only straighten the neck area, which can strain the back and waist, and restrict the movement of the neck muscles already stiff due to turtle neck, further stiffening them. Furthermore, neck stretchers, while promoting a normal cervical curve, can also exacerbate turtle neck.

[0005] The present invention is intended to solve the above-mentioned problems and provides a headrest cushion that can maintain a state in which the chin of a prone user is pulled and the neck is relaxed, thereby obtaining a posture correction effect through stretching using gravity.

[0006] In order to achieve the above object, the headrest cushion of the present invention comprises: a support cushion member that has a horseshoe shape when viewed from a plan view and supports the edge of the face and chin of a prone user; and a height adjustment member that is provided on the lower side of the support cushion member to position the support cushion member at a predetermined height so that the head of the user resting on the support cushion member is positioned higher than the feet, and to tilt the support cushion member downward toward the front in the direction in which the crown of the head of the prone user faces.

[0007] In addition, the height adjustment member may include a first height adjustment member that is formed to have a ring shape when viewed from a plane and whose height gradually decreases from the rear end of the side toward the center of the front end, and to which a support cushion member is coupled on the upper side.

[0008] In addition, the central portion of the rear side of the upper surface of the first height-adjusting member may be formed to have a concave shape in the left-right direction, with a portion of the support cushion member located on the upper side thereof that is open toward the rear.

[0009] In addition, the height adjustment member may further include a second height adjustment member that is formed to have a ring shape when viewed from a plane and has a constant height as a whole, and has a central portion of the front end formed to be convex upward so that the entire upper surface is in contact with the entire lower surface of the first height adjustment member.

[0010] In addition, the support cushion member and the first height-adjusting member, and the first height-adjusting member and the second height-adjusting member can be mutually connected by a protruding groove structure.

[0011] According to the present invention, the headrest cushion can be positioned at an appropriate height for the user's body through the height-adjusting member, and when the user lies face down with the head positioned higher than the feet and the face rests on the headrest cushion, the chin is pulled and the posterior muscles of the neck are relaxed. While maintaining this state, stretching using gravity occurs, so even without stretching that strains the body, the effect of posture correction can be achieved by resolving body imbalances such as turtle neck and rounded shoulders.

[0012] And, through the breathing hole formed in the height-adjusting member, a user lying face down with his or her face pressed against the headrest cushion can breathe comfortably while using the present invention.

[0024] The present invention proposes a headrest cushion characterized by including: a support cushion member that has a horseshoe shape when viewed from a plan view and supports the edge of the face and the chin of a prone user so that the chin of a prone user can be pulled and the neck can be maintained in a relaxed state, thereby obtaining a posture correction effect through stretching using gravity; and a height adjusting member that is provided on the lower side of the support cushion member so that the support cushion member is positioned at a predetermined height so that the head of the user resting on the support cushion member is positioned higher than the feet, and the support cushion member is arranged to be inclined downward toward the front in the direction in which the crown of the head of the prone user faces.

[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 headrest cushion of the present invention will be described in detail with reference to the attached drawings 1 to 11.

[0027]

[0028] The headrest cushion (A) of the present invention supports the head of a prone user, and includes a support cushion member (100) on which the user's face rests, as shown in FIGS. 1 to 5, and a height adjustment member (200) provided on the lower side of the support cushion member (100).

[0029] The support cushion member (100) is formed in a horseshoe shape when viewed from the plane as shown in FIGS. 6 and 10, and is positioned so that the open portion faces rearward to support the edges of the face (forehead, both cheeks) and the chin of a prone user, so that the user can comfortably lie prone with the eyes, nose, and mouth accommodated on the inside of the support cushion member (100). It is preferable that the support cushion member (100) be formed to have a strength sufficient to support the head while maintaining a predetermined height, and may be formed to have a left-right width such that the outer edge is positioned outside the user's head and the inner edge is positioned inside the user's head contour.

[0030] In addition, the support cushion member (100) is formed so that the upper surface slopes downward from the outer edge toward the inside, so that the edge of the face and the chin are in close contact with the upper surface while the eyes, nose, and mouth are accommodated on the inside, so that the user can maintain a stable prone posture with minimal contact with the face. For example, the front center portion of the upper surface of the support cushion member (100) where the forehead is rested may be formed to have an incline of about 5 to 10 degrees, and the remaining portion may be formed to have a greater incline (for example, about 30 to 40 degrees) than the front center portion.

[0031] And the support cushion member (100) is formed so that the upper surface forms a downwardly sloping curved surface toward the inside and is open toward the rear, so that a user whose face edge and chin are supported by the upper surface can breathe smoothly even when lying face down and feel a sense of visual openness and mental stability.

[0032] The height adjustment member (200) is provided on the lower side of the support cushion member (100) as illustrated in FIGS. 1 to 5 so that the support cushion member (100) is positioned at a predetermined height, and is arranged so that the support cushion member (100) is inclined downward toward the front. Here, the predetermined height at which the support cushion member (100) is positioned means a height at which the head of a user lying face down on the support cushion member (100) is positioned higher than the feet, as illustrated in FIG. 11. In other words, it refers to a state in which the user lying face down is inclined upward with respect to the floor toward the front in the direction in which the crown of the head of the user lying face down is directed. The angle that the user lying face down makes with respect to the floor may be about 10 to 20°, but is not limited thereto, and may vary depending on the circumference of the user's upper and lower body. However, a user who is lying face down with his head supported by a headrest cushion (A) with an upward slope forward can have his pelvis and shoulders supported together using another cushion to maintain a stable lying state while strengthening the balance of the pelvis and shoulders, and his shoulders can be supported by a shoulder rest cushion (B) to ensure that both shoulders are straightened to maximize the correction effect of turtle neck and rounded shoulders.

[0033] As illustrated in FIG. 5, the height-adjusting member (200) is arranged so that the support cushion member (100) provided on the upper side thereof is inclined downward toward the front. That is, the entire body of the user lying face down except for the head is inclined upward toward the front, and the head resting on the support cushion member (100) is horizontal or inclined downward toward the front. Accordingly, the user lying face down with the head positioned higher than the feet and the face resting on the headrest cushion (A) can have the chin pulled in, the posterior muscles of the neck relaxed, and the ears and shoulders positioned on the same plane. This posture of the user is the same as / similar to the posture of a user standing up with a normal neck, not a turtle neck. Since stretching is performed using gravity while the user assumes this posture, it is possible to resolve body imbalances, including turtle neck and rounded shoulders, without having to do any stretching that strains the body.

[0034] The height adjustment member (200) may include, for example, a first height adjustment member (210) having a ring shape when viewed from a plan view, as illustrated in FIGS. 1 to 5 and FIG. 7, and having a support cushion member (100) coupled to the upper side. Specifically, the first height adjustment member (210) may be formed to have a left-right thickness such that the inner edge is positioned further outward than the inner edge of the support cushion member (100), and the outer edge is positioned further inward than the outer edge of the support cushion member (100). And the first height adjustment member (210) is formed so that the height gradually decreases from the rear end of the side toward the center of the front end, so that when the first height adjustment member (210) is placed horizontally, the upper surface of the first height adjustment member (210) is inclined downward toward the front, and accordingly, the support cushion member (100) placed on the upper side can be arranged to be inclined downward toward the front.

[0035] The central portion of the rear side of the upper surface of the first height adjustment member (210) is positioned such that a portion that is open toward the rear from the support cushion member (100) is positioned thereon, and as illustrated in FIGS. 3 and 7A, is formed to have a concave shape in the left and right directions, so that a user lying face down with their face resting on the support cushion member (100) can breathe comfortably. In addition, the front end of the first height adjustment member (210) is formed so that the height gradually decreases toward the center, so that the bottom surface can be formed to have a convex shape upward. Accordingly, when the first height adjustment member (210) is placed on the ground, the vicinity of the center of the front end of the first height adjustment member (210) is spaced from the ground, so that a breathing hole can be secured toward the front. In addition, the first height adjustment member (210) may have at least one breathing induction hole (211) formed through the rear end thereof as shown in FIGS. 1 to 3 and FIG. 7 to additionally secure a breathing hole facing rearward.

[0036] In addition to the first height adjustment member (210) described above, the height adjustment member (200) may further include a second height adjustment member (220) coupled to the lower side of the first height adjustment member (210) as illustrated in FIGS. 1 to 5 and 8, and one or more second height adjustment members (220) may be provided. When a plurality of second height adjustment members (220) are provided as illustrated in FIG. 9, the plurality of second height adjustment members (220) may be coupled to be stacked on each other, and the first height adjustment member (210) may be coupled to the upper side of the second height adjustment member (220) located at the uppermost side.

[0037] This second height-adjusting member (220) may be formed, for example, in a ring shape when viewed from a plan view, to have a constant height as a whole. In this case, the constant height preferably means a height lower than the maximum height of the first height-adjusting member (210). In addition, the second height-adjusting member (220) may be formed to have a left-right thickness such that the inner edge matches the inner edge of the first height-adjusting member (210) and the outer edge matches the outer edge of the first height-adjusting member (210).

[0038] In addition, the second height adjustment member (220) can be formed so that its entire upper surface can be in contact with the entire lower surface of the first height adjustment member (210) as illustrated in FIGS. 2 to 5, and accordingly, the front central portion of the second height adjustment member (220) can be formed to be convex upward so as to correspond to the front central portion of the lower surface of the first height adjustment member (210). When such a second height adjustment member (220) is placed on the ground, a breathing hole is formed between the front central portion of the second height adjustment member (220) and the ground as illustrated in FIG. 4.

[0039] Meanwhile, the support cushion member (100) and the first height adjustment member (210), or / and the first height adjustment member (210) and the second adjustment member (220), may be mutually coupled in various ways. However, the support cushion member (100) and the height adjustment member (200) may be manufactured from EVA foam that has good elasticity and is easy to manufacture. In this case, in order to firmly couple each other, the support cushion member (100) and the first height adjustment member (210), and the first height adjustment member (210) and the second height adjustment member (220) may be configured to be mutually coupled by a protruding groove structure.

[0040] For example, as illustrated in FIGS. 1, 6, and 8, the first height-adjusting member (210) and the second height-adjusting member (220) may have a fastening protrusion (320) formed protrudingly in the front-back direction on the side of the upper surface thereof, and the support cushion member (100) and the first height-adjusting member (210) may have a fastening groove (310) formed recessedly in the bottom surface thereof corresponding to the fastening protrusion (320). Therefore, when the support cushion member (100), the first height-adjusting member (210), and the second height-adjusting member (220) are stacked in the vertical direction through the connection between the fastening protrusion (320) and the fastening groove (310), not only are they firmly coupled, but also the user lying face down can comfortably breathe with their face in close contact with the support cushion member (100) through the breathing holes formed toward the front and rear.
