Description

FIELD OF TECHNOLOGY TO WHICH THE INVENTION RELATES

The present invention relates to a neck support device, and in particular to a neck support device provided with three independent inflatable airbags, which can be adjusted in this device so that the user can independently inflate or deflate the inflatable airbags, thereby thereby modifying the appearance, size, height, and stiffness of the neck support device and adjusting the force exerted by the neck support device on the user's neck and head to provide improved neck and head support and help restore and maintain a neutral anatomical, spinal-flat head position , cervical spine and upper thoracic spine for both back and side sleepers. The neck support device of the present invention is comfortable for use by both back sleepers and side sleepers, resembles a comfortable pillow, and the user can use the neck support device when going to bed or sleeping.

BACKGROUND OF THE INVENTION

Conventional pillow designs simply involve making an inflatable shell and stuffing it with soft, lightweight materials such as cotton balls, shaped foam, foam pieces, or other lightweight, soft materials. Although ordinary pillows may have some softness and resilience at the beginning, but with prolonged use, the softness of the pillows gradually decreases, and therefore their ability to serve as a support deteriorates. When using pillows that are made of soft lightweight materials, after prolonged pressure on them by the head and neck, these pillows lose their shape, and the angle of the user's head when the user rests his head on the pillow will become too low or too high, resulting in excessive fatigue and tension of the muscles of the neck, causing pain in the neck and shoulders, cervicogenic headaches, and adversely affects the smoothness of breathing. In addition, the soft and lightweight materials in conventional pillows can also warp and clump as a result of prolonged compression, resulting in poor breathability. Pillows with poor air permeability can have limited airflow in the pillows and cause health problems for users who typically sleep in a prone or side position, and may even pose greater safety concerns for a user suffering from sleep apnea. In addition, the regular pillow does not adapt to the different body contours and sleep habits of different users, and its height cannot be adjusted to the height of the user's neck and head in order to provide proper support for, and restore and maintain a neutral anatomical, spinal-flat position of the head, cervical spine and upper thoracic spine of the user. More specifically, with regard to molded profiled pillows, otherwise known as orthopedic pillows, for example, the types of foam used in the molded profiled pillow may be too soft or too hard. The molded profiled cushion made from high density resilient foam can be very hard and rigid and if the shape is not consistent with the shape of the user, the user may experience neck pain and discomfort. On the other hand, even though a shaped pillow made from softer memory foam can conform better to the shape of the wearer's neck and head than a pillow made from high-density resilient foam, it is usually too soft and does not recover to its original molded shape. profile. In addition, this pillow flattens during use and therefore does not conform to the shape of the wearer's head and neck. Further, since the materials inside a traditional pillow are uniform throughout the entire volume of the pillow, the softness or firmness over the entire surface of such a pillow is the same and does not change according to the different softness/hardness requirement of different parts of the user's body, such as the head and neck. As a result, the lack of support for the head and neck of the user causes pain and inconvenience to the user. If the foam density of the pillow is too high or too low, then the pillow becomes uncomfortable and in turn causes pain to the user. Misalignment of the shapes of the molded foam pillow and the user's neck and head also results in discomfort and pain.

The seriousness of the aforementioned problems becomes more apparent only in view of the fact that the cervical vertebrae connect the skull on the upper side and the thoracic spine on the lower side, and their significance is self-evident. However, more recently, people have been suffering from cervical spondylosis (also called cervical spine syndromes), mainly due to whiplash injuries in accidents, sports injuries or falls, and mainly due to poor lifestyle habits (for example, prolonged use of mobile phones). telephones, game consoles or computers, head-down posture or incorrect standing or sitting posture), work needs (such as driving) that require you to keep your neck in a constant position for a long time, or excessive psychological pressure, etc. These factors cause the user's neck muscles to remain highly tense for a long time, the muscles become rigid and contracted for a long time, and a harmful wrong posture of the cervical spine is adopted, which even causes degeneration of the cervical spine joints or degeneration and herniation of the intervertebral discs (so how they experience excessive compression) and further leads to an even greater predisposition to pinching of the nerves, arthritis, joint pain and premature degeneration or thinning of the intervertebral discs, etc., and, ultimately, the development of symptoms such as throbbing pain in the arm , hand numbness, chronic headache, chronic fatigue, insomnia, chronic neck and shoulder pain, etc.

For the most part, cervical spondylosis, especially the chronic dysfunction of the neck and shoulders, can be due to conditions such as neck and shoulder stiffness or excessive compression of the cervical spine joints, which causes irritation and nerve entrapment. Such a patient may suffer from neck pain almost every day, and the pain may be particularly aggravated after a full day of work, making it difficult for the patient to relax and fall asleep at night. In addition, the conventional commercially available pillow provides little, if any, benefit to the patient with cervical spondylosis; on the contrary, after a long rest on such a pillow, the patient may suffer from even more severe pain in the neck and shoulders, headache and/or pain or numbness of the hands.

Indeed, most patients are often unable to allocate the time or money required for conventional treatment, leaving such patients untreated and suffering from pain that could be partially relieved. In addition, many of the patients treated with conventional methods did not receive care from the proper medical professionals capable of providing treatment according to the needs of the patients. Therefore, the pain in these patients was not effectively removed. In case of not receiving treatment or receiving ineffective treatment, some patients try to take pain medications, use ointments or patches, etc. However, their actions are limited, and long-term use of such drugs can have serious side effects.

Since the head and neck of different people have unique sizes, shapes, lengths and flexibility, creating a regular stuffed pillow or molded profiled pillow that can fit and properly support each person's head and neck is an extremely difficult task. Further, since people tend to move while sleeping, a traditional stuffed pillow or a molded profiled pillow cannot equally fit and properly support the user's head and neck when they sleep in the supine position and when they sleep on their right or left. side. That is, a one-size-fits-all pillow with a consistent density or shape simply cannot fit and properly support the wearer's head and neck in both side and back sleep positions equally well. In addition, sleeping on a pillow that does not support or maintain the wearer's head, neck, and upper back in a natural, neutral, spinal alignment can cause spinal misalignment, paraspinal muscle tension, nerve irritation, and pinching, which can in turn , lead to acute and chronic pain in the neck and shoulders, cervicogenic headaches, and numbing pain in the upper extremities. Discomfort and pain in the neck and shoulder further make it difficult for such a user to fall asleep or be able to sleep deeply.

That is, many people, whether sleeping on their back or sleeping on their side, do not receive proper support for the cervical spine and cannot regain and maintain a neutral anatomical, spinal-flat position of the head, cervical spine, and upper thoracic spine when they are at rest. or sleep, and therefore suffer from chronic headaches, dysfunctions of the neck and shoulders and the resulting pain due to muscle stiffness, excessive compression of the joints of the cervical spine, herniated discs, entrapment and irritation of the paraspinal nerves, etc., and therefore from deterioration in health and quality of life without having a good affordable solution. Accordingly, it has become an important object of the present invention to effectively solve the aforementioned problems in such a way that a suitable neck support device can be obtained for back sleepers or side sleepers, adapting to the contour of the neck or sleep pattern, with improved sleep comfort. or rest, and did not require much time and/or money to be spent on the treatment of the cervical spine, but it was possible to alleviate and/or prevent cervical spine syndromes by themselves with the help of a suitable and adjustable neck support.

SUMMARY OF THE INVENTION

One aspect of the present invention relates to a neck support device, which may be in the form of a pillow and contain three built-in adjustable air cushions, for example, inflatable airbags in three separate empty cavities within the neck support device. In some embodiments, the neck support device may be made from molded composite foam. The combination of adjustable inflatable airbags and the neck support material can function to lift the head and/or face of a wearer, sleeping either on their back or on their side, up until their head, cervical spine, and upper thoracic spine the spine does not align along a straight line. This adjustable inflatable neck support device allows the user to adjust the neck support device to support the head, neck and upper back in their natural neutral anatomically-level position, thereby preventing tension and pain whether or not the user is resting. or sleeps in side or back lying positions.

In some embodiments, the neck support device includes, in a front-to-back direction, a support portion including a central support portion and a first inflatable air bladder and a carrier portion. The carrier portion can support the back of the user's head when the user is in a supine position. The upper surface of the bearing section has a height less than the height of the upper surface of the supporting section. The central bearing portion is disposed on the central portion of the bearing portion. The central support part has an upper surface configured to provide support for the user's neck and a lower surface provided with a first cavity in the form of a notch. The first inflatable air chamber may be placed inside the first cavity, expand or contract along the displacement axis, and displace the upper surface of the central support portion along the displacement axis. The neck support device further includes two second inflatable air chambers and an inflation device. Each of the two second inflatable air chambers can be placed inside the corresponding one of the second cavities, which are provided in the form of recesses in the lower surface of the support device for the neck and are located on opposite sides of the first cavity, expand or contract along the displacement axis and displace the upper surface of the support device for neck along the axis. The inflation device may be connected to the first inflatable air chamber and the second inflatable air chambers, respectively, and inflate or deflate the first inflatable air chamber and the second inflatable air chambers together or separately to change the expansion or contraction ratio of the first inflatable air chamber and the second inflatable air chambers. . In addition, the pumping device can be either manually operated or powered pumping device. Therefore, the user can independently control the inflation device to adjust the degree of expansion or contraction of the first inflatable air chamber and the second inflatable air chambers in order to change the force applied to the neck by the central support portion and/or areas of the upper surface of the neck support device that correspond to according to the position of inflatable air chambers, in order to restore and maintain a neutral anatomical, spinal-flat position of the head, cervical spine and upper thoracic spine.

In some embodiments, the inflation device includes a plurality of tubular parts, a first air valve that can be assembled with one of the tubular parts, at least one second air valve that can be assembled with another of the tubular parts, and at least one area for pumping. The inflation section is connected to the first inflatable air chamber and the second inflatable air chambers by means of tubular parts, inflates and deflates the first inflatable air chamber when the first air valve is open, and inflates and deflates the second inflatable air chambers when the second air valve is opened.

In some embodiments, the first and second cavities are sized to provide the first and second inflatable airbags with enough space required for various levels of expansion as desired by the user when inflating the airbags so that the user can adjust the level of stiffness/ softness and height of the neck support according to the individual requirements of the user. At least one of the air chambers may be designed with an expandable top end and a non-expandable or minimally expandable base, and therefore most of the expansion of the air chambers, when inflated, may occur on the top side of the air chambers and towards the user resting on the support device for neck, and downward expansion towards the bottom of the neck support device can be minimized, resulting in the air chambers being pushed upward towards the wearer's neck and head when inflated, since downward expansion of the airbags can cause excessive directional forces. outward expansion on the structure of the supporting device S for and, in turn, its damage. That is, such a minimally flexible/expandable base of the airbox prevents possible damage to the structure of the neck support device when the expansion is directed upwards towards the user.

In some embodiments, the first inflatable air bladder, which may be located in the first cavity, is semi-tubular and has a rounded front end that must face the upper inner surface of the first cavity, and an opposite second end that is a flat base and must be facing the lower opening of the first cavity. When inflated, for example, by a user actively inflating air into the first inflatable air bladder, the first inflatable air bladder rises upward towards the back of the cervical spine of the user who is resting on the neck support device in the supine position and can conform to the anatomical shape his cervical spine. When the user inflates the airbag to a level of height and softness/hardness that provides the desired customization for the user through the combined effect provided by the inflated airbag and the neck support material that accommodates the airbag, such as orthopedic shape memory foam, the support device for neck can comfortably accommodate the slightly lordotic curvature of the user's cervical spine in the supine position and provide individually adjusted support for their head and neck so that the head, neck and upper back are held in a natural and neutral anatomically-level position to prevent strain and pain that the user may otherwise experience when lying on their back.

In some embodiments, the second inflatable airbags, which may be located in the second cavities, form the side portions of the neck support device on which the head, face, and neck of the wearer rests when the wearer lies on the side of the neck support body. The second inflatable airbags, when uninflated, are larger in length and/or volume than the first inflatable airbag, when uninflated, to provide a larger surface area that can cover areas of the body including most of the surface area of the side profile of the head and face resting on it. Each of the second cavities is larger than the first cavity. At least one of the second inflatable air chambers has a flat upper end, which must face the upper inner surface of the corresponding second cavity, and a flat lower base, which is opposite the flat upper end, and must face the lower opening of the second cavity. The flat bottom base is inflexible/non-expandable and can minimize downward expansion when the second inflatable airbag is inflated by the user. The flat top end is expandable and expands upwardly towards the side of the user's head, face and neck during inflation. Each of the second inflatable air chambers located in the second cavities and side portions of the neck support device can support the wearer's head and neck resting on a respective side portion, such as the right side portion, when the user lies on the right side of the neck support device. , or left side portion when the user lies on the left side of the neck support device. In addition, the airbags are sized to provide a wide range of support and lift that is suitable for both adults and children, as well as people with different head and neck sizes, shoulder widths, and neck stiffness.

In some embodiments, the top and sides of at least one of the air chambers are made from a soft and flexible thermoplastic material to allow for easy expansion at low pressure and with minimal air leakage over time and to eliminate excessive noise generated by user movement on the support device. for the neck, which may otherwise interfere with the user's sleep.

In some embodiments, the inflation portion that inflates the second inflatable air chambers located in the second cavities is independent of the inflation portion that inflates the first inflatable air chamber located in the first cavity, or the neck support device contains different valves for creating separate systems for pumping the second inflatable air chambers and the first inflatable air chamber. Separate inflation slots or air valves that create separate inflation systems serve to provide different inflation/expansion volumes required for the air chambers, as the volume of inflation/expansion required for the first inflatable air chamber can, and often does, differ from the corresponding volume. for the second inflatable air chambers. When the user inflates the second inflatable airbag to obtain the desired level of height and softness/stiffness of the side portion of the neck support device, the second inflatable airbag rises towards the head, face and neck of the user resting on the right or left side of the body in the side portion.

In some embodiments, the pumping station(s) may be one or more manual pumps, such as manual pumps, or more mechanized pumps, such as electric pumps, and the air chambers may be pumped by the pumping stations using different arrangements of the tubular parts, for example, the second inflatable airbags are connected to the tubular parts so as to inflate or deflate at the same time, while the first inflatable airbag is independent of the interconnection of the tubular parts and the second inflatable airbags, and therefore the inflation and deflation of the first inflatable The air chamber can be adjusted independently of the second inflatable air chambers.

In some embodiments, the inflation device includes only one hand pump or motorized pump and a plurality of air valves and tubular assemblies to control airflow into and out of the various air chambers.

In some embodiments, the air chambers are nested deep within the first and second cavities within the neck support device, and each chamber is closed at least on the sides and top of the pillow body, which may be molded from foam, to provide maximum comfort. In contrast, if the neck support device is designed to contain only inflatable airbags, without foam or other materials to cover the airbags, then the neck support device will be uncomfortable for the wearer and will not effectively fit the user's head and neck. The design of the neck support device of the present invention better takes into account and ensures the fit of the air chambers, the ductility of the material(s) from which the neck support device is made, and its orthopedic shape, to allow the user to easily make adjustments. support device for the neck, and thereby adjust to his needs its height, softness/hardness, size and/or shape, which he finds most comfortable when lying on his back or sides.

In some embodiments, the area of the neck support device in which the back of the head of the supine user rests on the neck support device is softer than the area that conforms to the user's neck so that the head can be comfortably pressed into the pillow, and the corresponding neck area is stiffer to provide improved neck support. For example, the central support portion is stiffer than the central portion of the carrier portion which corresponds to the back of the head when the user rests their neck on the central support portion.

In some embodiments, the region of the neck support device in which the back of the head of the supine user rests on the neck support device is softer than the side regions, and the side regions, which are more rigid, may provide more stable support when the user lies on their side. For example, the side portions of the cushion body, which include respective portions of the support portion and the carrier portion and correspond to the second cavities, are stiffer than the remainder of the carrier portion.

In some embodiments, a plurality of holes may be made in the body of the cushion to provide a difference in stiffness. The central area of the neck support device, on which the back of the head rests, has larger holes drilled into it to make the pillow body material(s) softer and more deformable under the weight of the head. Other areas of the neck support device where more stable support is desired may include smaller openings to reduce the softness or potential for the pillow body material(s) to deform under the weight of the head in such areas. Such holes made in the material(s) of the body of the pillow also make the pillow more breathable for the wearer to breathe, cooler to sit on and easier to move around. That is, holes of different sizes in different areas of the neck support device further improve the shape auto-adjustment characteristics of the neck support device to provide more comfort to the user. In some embodiments, the body of the pillow may be provided with a pillow cover, which is a removable paper or fabric that is secured with physiotherapy sites such as electrode blocks, or a conventional pillow cover. The physiotherapy areas are arranged to be co-ordinated with at least one of the positions on the back of the neck and upper parts of the shoulders of the user when he lies on the support device for the neck in the supine position. For a user suffering from neck and shoulder pain and desiring to receive electrotherapy, the removable tissue or tissue secured by the physiotherapy areas in such positions of the present invention allows the user to easily receive targeted electrotherapy for symptoms such as headaches and/or pain in the neck and shoulders without necessarily knowing where to place the physiotherapy areas on the back of the neck and upper shoulders for effective treatment. The physiotherapy areas on the pillow cover are positioned to stimulate the nerves and muscles of the upper neck and lower neck and shoulder joint. These physiotherapy sites can be used with or made from electrically conductive materials and/or adhesive gel and can be connected to or used with an electrotherapy device used to relieve muscle tension and pain.

In some embodiments, the first inflatable air chamber may expand to a state of maximum expansion, wherein the maximum height of the first inflatable air chamber in the direction of the displacement axis is between 5.5 cm and 9.5 cm.

In some embodiments, at least one of the second inflatable air chambers may expand to a state of maximum expansion, wherein the maximum height of the second inflatable air chamber in the direction of the displacement axis is from 6.5 cm to 10.5 cm.

In some embodiments, at least one of the physiotherapy portions is secured to the pillow cover in a position that corresponds to the position of the central support portion, and may be adjacent to the user's neck and electrically connected to the physiotherapy device to receive electrical power transmitted from the physiotherapy device.

In some embodiments, at least one of the physiotherapy sites is provided with an electrotherapy unit that can receive electrical power transmitted from the physiotherapy device and provide electrical stimulation to the user's neck.

In some embodiments, at least one of the physiotherapy sites is provided with a thermotherapy unit that can receive electrical power transmitted from the physiotherapy device and generate heat to warm the user's neck.

In some embodiments, at least one of the physiotherapy sites is provided with a combined electrotherapy-thermotherapy unit that can receive electrical power transmitted from the physiotherapy device, provide electrical stimulation to the user's neck, and generate heat to heat the neck.

In some embodiments, the first inflatable airbag and the second inflatable airbags are located within the pillow body, with the inflation device outside the pillow body and pillowcase, and the tubular portions may extend into the pillow body through the pillowcase.

Another aspect of the present invention relates to a method for manufacturing an adjustable inflatable neck support device. The method includes the steps of: forming a pillow body having a support top surface that can serve as a support for the user's neck, a bearing top surface that can support the back of the user's head when the user is in a supine position, and a bottom surface that can support the user's neck. made with the first cavity and two second cavities located on opposite sides of the first cavity, while the bearing upper surface has a height less than the height of the supporting upper surface; forming a bottom plate having edges consistent with lower inner edges of the pillow body; placing the first inflatable air chamber in the first cavity, placing two second inflatable air chambers in the second cavities, respectively, and assembling the tubular portions with the first inflatable air chamber and the second inflatable air chambers; and assembling the pillow body to the bottom plate by adhesively bonding the lower inner edges of the pillow body to the matching edges of the bottom plate to form an adjustable inflatable neck support device with a first inflatable air chamber and second inflatable air chambers contained within the adjustable inflatable neck support device.

For example, "substantially" may indicate that the value is within, for example, ±5%, ±3%, ±1%, ±0.5%, or ±0.1%, or one or more standard deviations from a particular value.

One aspect of the present invention relates to an adjustable inflatable neck support device. For ease of understanding only, unless the context clearly requires otherwise, the lower right side of FIG. 1 is referred to as the front sides of the components shown in FIG. 1, upper left side in FIG. 1 is referred to as the rear sides of the components, the upper right side in FIG. 1 is referred to as the right sides of the components, the lower left side in FIG. 1 is referred to as the left sides of the components, the top side in FIG. 1 is referred to as the top sides of the components, and the bottom side in FIG. 1 is designated as the undersides of the components. However, the present invention is not limited to this. In some embodiments, the adjustable inflatable neck support S may be divided from front to back into at least a support portion S1 and a carrier portion S2. The shape of the upper surfaces of the support portion S1 and the bearing portion S2 are ergonomically designed to conform to the natural curvature of the cervical spine, and therefore the upper surface of the bearing portion S2 has a height less than the height of the upper surface of the bearing portion S1.

As shown in FIG. 1, 3 and 4, when the user is resting on the neck support device S in the supine position, the support portion S2 falls on and supports the back of the user's head (as shown in FIG. 3), while the support portion S1 falls on and supports the user's neck. As shown in FIG. 5 and 6, when the user is lying on their side on the neck support device S, the support portion S2 rests on and supports the side of the user's head (as shown in FIG. 6), while the support portion S1 rests on and supports the side of the neck. user. The contour of the support portion S1 is consistent with the natural cervical lordosis of the human cervical spine to provide an appropriate support force to assist the user in restoring the correct position and posture of the head, cervical spine and upper thoracic spine to natural states. Further, since the neck support device S is resilient when the user rests on the neck support device S, the neck support device S deforms so that the top surface conforms to the contour of the user's head and neck and provides support and support actions.

As shown in FIG. 7 and 8, the neck support device S includes a pillow body 1 and a pillow case 2. The pillow case 2 is provided with a containing space 20 and is configured to cover the main part 1 of the pillow so that the main part 1 of the pillow can be located in the containing space 20. blocks, and have a profile consistent with the contour of the main part 1 of the pillow. However, the present invention is not limited to this. In some embodiments, the pillow case may be a regular pillow case. Since the contour of the pillow case 2 conforms to the contour of the pillow body 1, when the pillow body 1 is placed in the pillow case 2, the structure of the pillow body 1 can still be clearly indicated by the contour of the pillow case. Accordingly, in FIG. 1, for ease of description only, the positions of the components of the pillow body 1 to be described below are also indicated at the corresponding positions on the pillowcase 2.

As also shown in FIG. 7 and 8, in some embodiments, the pillow body 1 may be made of foam and/or other elastomer and/or filling/padding material and may have a support portion S1 and a bearing portion S2. The central portion of the support portion S1 is provided with a central support portion 11. The upper surface of the central support portion 11 can serve as a neck support for the wearer (as shown in FIG. 3). Further, in order to better provide a neck support effect, the front side of the central support portion 11 protrudes forward so as to support the whole or almost the whole neck of the wearer. Accordingly, when the central support portion 11 rests against and supports the user's neck, the user's head will naturally tilt back, which helps to fix the user's head more firmly on the support portion S2. In some embodiments, the central support portion 11, which conforms to the neck of the user, is more rigid than the central portion of the bearing portion S2, which conforms to the back of the head of the user, when the user leans his neck on the central support portion 11. The difference in stiffness between the central support portion 11 and the center portion of the support portion S2 allows the head to be comfortably pressed into the pillow body 1, while the central support portion 11 can provide sufficient support for the neck. In some embodiments, the difference in stiffness is created by differences in density, total area of holes, diameter and/or location of holes made in the body 1 of the pillow. For example, the foam of the center portion of the carrier portion S2 may comprise more densely spaced holes, larger holes and/or holes of a larger diameter than the holes made in the central support portion 11 so that the central portion of the carrier portion S2 is softer than the central support portion 11, and the central support portion 11 had a higher support capacity. In some embodiments, the central support portion 11 is more rigid than the entire bearing portion S2.

As shown in FIG. 7 and 8, the first cavity 110 may be recessed in the lower surface of the central support portion 11, and the first inflatable air chamber 13 may be accommodated in the first cavity 110. At least the upper inner surface of the first cavity 110 is expandable in the first maximum expansion ratio. upwards to provide the first inflatable air chamber 13 with a sufficient amount of space required for various levels of expansion, as desired by the user, when he inflates the first inflatable air chamber 13, to adjust according to his individual requirements the level of hardness/softness and the height of the corresponding upper surface of the support device S for the neck. The first maximum degree of upward expansion may be 5-9 cm, and in some embodiments, 6.5-7.5 cm. 8, which may be made of plastic, metal, or other material that is non-expandable, minimally expandable, or less expandable than foams, and therefore most of the expansion of the first inflatable air chamber 13, when inflated, occurs on the upper side of the first inflatable air chamber 13 , which faces the upper surface and is directed towards the neck and head of the wearer resting on the neck support device S, while restraining the expansion down to the bottom of the neck support device S and therefore restraining excessive outward expansion forces acting on the bottom structure of the support device S for the neck, which may cause damage to the supporting device S for the neck, and the direction, together with the expandable upper inner surface of the first cavity 110, expansion upward. In some embodiments, the first cavity 110 may be formed by a selection of a molded foam containment space that, at a first maximum upward expansion ratio, gives the first inflatable air bladder 13 space to expand to various levels. Additionally, it should be noted that since the first cavity 110 can accommodate the first inflatable air chamber 13 and allow the first inflatable air chamber 13 to expand or contract to displace the upper surface of the central support portion 11, the first cavity 110 is defined as located within the lower surface of the central support portion 11 The first inflatable air bladder 13 may be inflated to expand or deflated to contract along an axis of displacement (eg, the Z-axis shown in FIG. 7). In some embodiments, the uninflated first air bladder 13 has a volume of 9-21 cm ³ , in some embodiments, 14-17 cm ³ , while the uninflated first air bladder 13, respectively, adjoins the upper side to the upper inner surface and has the bottom side is flush with the bottom opening of the first cavity 110 along the displacement axis, that is, also adjacent to the bottom plate 16 if the bottom plate 16 covers the bottom opening, and the sides of the uninflated first inflatable air chamber 13, respectively, are adjacent to the four side inner surfaces first cavity 110 along the longitudinal axis of the cavity of the first cavity 110, which is perpendicular or substantially perpendicular to the axis of displacement and parallel or substantially parallel to the anteroposterior direction of the neck support device S, and along the transverse axis of the cavity of the first cavity 110, which is perpendicular to or, substantially perpendicular to the longitudinal axis of the cavity and parallel or substantially parallel to the right-to-left direction of the neck support device S. By adjoining the first inflatable air chamber 13 in an uninflated state to the inner surfaces of the first cavity 110, the expansion of this chamber causes the first cavity 110 to expand more effectively, since the delay time between their coordinated expansions, which can otherwise occur when between the first cavity 110 and the uninflated first air chamber 13 there are gaps. However, the present invention is not limited to this, and in some embodiments, at least one of the upper and lower sides of the uninflated first inflatable air chamber 13 is not adjacent to the upper inner surface or is not located flush with the lower opening of the first cavity 110 along the displacement axis, and/or at least one of the sides of the uninflated first inflatable air chamber 13 is not adjacent to any of the four side interior surfaces of the first cavity 110 along the longitudinal cavity axis or the transverse cavity axis of the first cavity 110.

When the first inflatable air bladder 13 expands or contracts along the displacement axis, the expansion or contraction displaces the upper surface of the central support portion 11 along the displacement axis, for example, up or down. In some embodiments, the first inflatable air bladder 13 is semi-tubular and has a rounded front end that faces the upper inner surface of the first cavity 110 and an opposite second end that is a flat base that faces the lower opening of the first cavity 110. In some embodiments, the flat base is inflexible or minimally expandable, and when the first inflatable airbag 13 is inflated, the expansion ratio along the displacement axis of the first end exceeds the expansion ratio of the second end. When the first inflatable air bladder 13 is inflated, the first inflatable air bladder 13 may expand upward towards the rear side of the user's cervical spine when the user is resting in a supine position on the central support portion 11 of the neck support device S, and cause an upward movement of the displaceable corresponding the upper surface of the central support portion 11 to conform to the anatomical shape of the cervical spine, for example to conform to the slightly lordotic curvature of the user's cervical spine. In some embodiments, when the first inflatable airbag 13 is inflated to expand to the first state of maximum expansion, the maximum height of the first inflatable airbag 13 in the direction of the displacement axis is from 5.5 cm to 9.5 cm or, in some embodiments, from 7 cm up to 8 cm. However, the present invention is not limited to this. Accordingly, when the user inflates the first inflatable air bladder 13 to a level of height and softness/hardness that provides the desired adjustment to the user due to the inflated first inflatable air bladder 13 and the material(s) of which the neck support device S is made, and fixes the inflated first air bladder 13, the upper surface of the neck support device S, which corresponds to the inflated first air bladder 13, can comfortably conform to the curvature of the user's cervical spine when the user is resting in the supine position. Additionally, through the combined actions provided by the adjustable inflatable air bladder 13 located within the material of the neck support device S, such as orthopedic shaped foam, an individually adjusted support can be provided to the user's head and neck to hold the head, neck and upper back in a natural position. and a neutral anatomically-flat position to prevent strain and pain when the user is lying on their side or back. As also shown in FIG. 7 and 8, in some embodiments, the neck support device S further includes at least two second inflatable airbags 19 in addition to the first inflatable airbag 13. Each of the second inflatable airbags 19 in an uninflated state is larger than the first inflatable air chamber 13 in the uninflated state, for example, the maximum cross-sectional area perpendicular or substantially perpendicular to the axis of displacement of the second inflatable air chambers 19 in the uninflated state exceeds the same area of the first inflatable air chamber 13 in the uninflated state by 120-170 cm ² or, in some embodiments, 135-155 cm ² , or exceeds 5-15 cm in length along the corresponding cavity longitudinal axis, or, in some embodiments, 8.5-11.5 cm in length along the corresponding cavity longitudinal axis and has a maximum expanded volume greater than the expanded volume of the first inflatable air chamber 13, for example, by 720-1800 cm ³ to displace, on the upper surface of the neck support device S, an area greater than the area on the upper surface of the neck support device S, displaced by the first inflatable air bladder 13 to cover a larger portion, for example more than 50%, of the side profile surface area of the user's head, face and neck when sleeping on their side on either side of the neck support device S. In the lower surface of the pillow body 1, two second cavities 190 can be formed in the form of recesses on two opposite sides of the first cavity 110 and near opposite ends of the pillow body 1, respectively, for example, one near the right side of the pillow body 1, and the other near the left side of the pillow body 1, that is, one cavity is closer to the right side of the pillow body 1 than its left side, and another cavity is closer to the left side of the pillow body 1 than its right side. Each second cavity 190 has a longitudinal axis of the cavity that is perpendicular or substantially perpendicular to the axis of displacement and parallel or substantially parallel to the anteroposterior direction of the neck support device S, and a transverse axis of the cavity that is perpendicular or substantially perpendicular to the longitudinal axis cavity and parallel or substantially parallel to the right-to-left direction of the neck support device S. In some embodiments, at least the length along the longitudinal axis of the cavity of the second inflatable air chambers 19 in the uninflated state exceeds the length of the first inflatable air chamber 13 in the uninflated state, for example, by 6-15 cm or, in some embodiments, by 8.5- 11.5 cm. Each of the second cavities 190 has an upper inner surface, the area of which is greater than the area of the upper inner surface of the first cavity 110, and a length along the longitudinal axis of the cavity, which is greater than the length of the first cavity 110, so that the displacement area on the upper surface of the support device S for the area on the upper surface of the neck support device S displaced by the first inflatable air bladder 13 in order to cover a greater part, for example more than 50%, of the surface area of the side profile of the head, face and neck of the user when he sleeps on his side on either side of the neck support device S. Each of the second cavities 190 may be located entirely within the support portion S1, so that the regions of the upper surface of the neck support device S corresponding in position to the second cavities 190 may be displaced by the expansion or contraction of the second inflatable air chambers 19 placed in the second cavities 190 to to adjust the height of such areas according to the height of the neck of the user, resting on his side, and provide proper support for his cervical spine. However, the present invention is not limited to this. In some embodiments, at least one of the second cavities 190 is located in both the support section S1 and the bearing section S2, wherein the first section of such second cavity 190 located in the support section S1 is the same as or larger than a second portion of such a second cavity 190 disposed in the carrier portion S2 so that the height of the regions of the upper surface of the neck support device S can be adjusted corresponding to the position of such second cavities 190 corresponding to the heights of both the neck and head of the wearer resting on their side, and provide proper support for and support for a neutral anatomical, spinal-flat position of the user's head, cervical spine and upper thoracic spine, without excessive head tilt. In some embodiments, the first portion of the second inflatable air chamber 19, which is located in the support portion S1, has a first maximum inflatable height of 6.5-10.5 cm, or in some embodiments, 8.0-9.0 cm. the portion of the second inflatable air chamber 19 which is located in the carrier portion S2 has a second maximum inflatable height of 5.5-9.5 cm or, in some embodiments, 7.0-8.0 cm. In some embodiments, the first maximum the inflatable height exceeds the second maximum inflatable height, and the ratio of the first maximum inflatable height to the second maximum inflatable height may be 1.11:1-1.90:1.

In some embodiments, the side sections of the pillow body 1, in which the second cavities 190 are located, consisting of the respective sections of the support section S1 and the bearing section S2, are more rigid than the rest of the bearing section S2, and have a rigidity not lower than the rigidity of the central support section. of the part 11 to provide more stable support when the user lies on their side on either side of the neck support device S. In some embodiments, the portion of the carrier portion S2 in the side portion where the second cavity 19 is located is softer than the portion of the support portion S1 in the side portion to allow the head to comfortably tuck into the pillow body 1 while the portion of the support portion S1 on sufficient support for the neck can be provided in such a side portion. Said difference in stiffness between the side section and the rest of the bearing section S2 and between the section of the bearing section S2 in the side section and the section of the support section S1 in the side section can be created by the density, the total area of the holes, the diameter and / or differences in the location of the holes made in the main part 1 pillow. In some embodiments, the material of the carrier portion S2, excluding the side portions, may comprise more densely spaced holes, larger holes, and/or larger diameter holes than the holes made in the side portions, so that the carrier portion S2, excluding the side portions, was softer than the side sections, and the side sections had more supportive ability. In some embodiments, the material of the portion of the bearing portion S2 in the side portion may comprise more tightly spaced holes, larger holes, and/or larger diameter holes than the holes made in the portion of the bearing portion S1 in the side portion, so that the portion of the bearing portion S2 in the side portion the section was softer than the section of the support section S1 in the side section, and the section of the support section S1 in the side section had a greater support ability. In some embodiments, the upper surface of the portion of the support portion S1, which is located on the side portion, has a first maximum offset of 2.1-5.7 cm and, in some embodiments, 3.5-4.3 cm. section S2, which is located on the side section, has a second maximum displacement of 1.4-5.0 cm and, in some embodiments, 2.9-3.5 cm. In some embodiments, the first maximum displacement exceeds the second maximum displacement, and the ratio of the first maximum displacement to the second maximum displacement is 1.14:1-4.07:1.

As also shown in FIG. 7 and 8, second inflatable airbags 19 may be placed in second cavities 190, respectively, and inflate to expand or deflate to contract along an axis of displacement (eg, the Z-axis shown in FIG. 7). At least the upper interior surface of each of the second cavities 190 is expandable in a second maximum upward expansion ratio to provide the respective second inflatable airbags 19 with a sufficient amount of space required for various levels of expansion as desired by the user when he inflates the second inflatable airbags 19, in order to adjust the firmness/softness levels and the height of the respective upper surface of the neck support device S according to your individual needs. The second maximum degree of upward expansion may be 6-10 cm or, in some embodiments, 7.5-8.5 cm. In some embodiments, only the top and sides of at least one of the first and second inflatable air chambers 13, 19 are expandable and its underside is non-expandable or minimally expandable. For example, only the tops and sides of the first and second inflatable air chambers 13, 19 are made of soft and flexible thermoplastic material to allow rapid top and side expansion even in response to low pressure inflation, which reduces the risk of air leakage over time, which may occur when the air chamber has a relatively high internal pressure, and reduces the likelihood of noises and, if any, their loudness, which may be generated by the movement of the user on the neck support device S, which may otherwise disturb the sleep of the user. The bottom opening of each second cavity 190 may be covered by a bottom plate, such as bottom plate 16 shown in FIG. 8, which may be made of plastic, metal, or other material that is non-expandable, minimally expandable, or less expandable than foams, and therefore most of the expansion of the second inflatable airbags 19, when inflated, occurs on the upper side of the second inflatable airbags 19 , which faces the upper surface of the neck support device S, and towards the neck and head of the user resting on this device, while restraining the expansion down to the bottom of the neck support device S and therefore restraining excessive outward expansion forces acting on the lower structure of the support device S for the neck, and the direction, together with the expandable upper inner surface of the second cavity 190, expanding upward. In some embodiments, the second cavities 190 may be formed by a selection of molded foam containing spaces which, at a second maximum upward expansion ratio, gives the second inflatable airbags 19 room to expand to various levels. In some embodiments, the uninflated second airbag 19 has a volume that is greater than the volume of the uninflated first airbag 13 and is 25-36 cm ³ or, in some embodiments, 28-33 cm ³ , while the uninflated airbag 19, respectively, adjoins the upper side to the upper inner surface and has the lower side flush with the lower opening of the corresponding second cavity 190 along the axis of displacement, that is, also adjacent to the bottom plate 16 if the bottom plate 16 closes the bottom hole, and the sides of the uninflated inflatable air the chambers 19 respectively adjoin the four side inner surfaces of the respective second cavity 190 along the longitudinal axis of the cavity and the transverse axis of the cavity of the second cavity 190. By adjoining the inflatable air chamber 19 in an uninflated state to the inner surfaces of the second cavity 190, the expansion of this chamber more effectively causes expansion the second cavity 190, since the delay time between their matched expansions, which can otherwise occur when there are gaps between the second cavity 190 and the uninflated second inflatable air chamber 19, is reduced. However, the present invention is not limited to this, and in some embodiments, at least one of the upper and lower sides of the uninflated second inflatable air chamber 19 is not adjacent to the upper inner surface or is not located flush with the lower opening of the second cavity 190 along the displacement axis, and/or at least one of the sides of the uninflated second inflatable air chamber 19 is not adjacent to any of the four side interior surfaces of the second cavity 190 along the longitudinal axis of the cavity and the transverse axis of the cavity of the second cavity 190.

When the second inflatable air bag 19 expands or contracts along the axis of displacement, the expansion or contraction moves the upper surface of the pillow body 1, and therefore also the upper surface of the pillowcase 2, along the axis of displacement, for example up or down, which may also contribute to additional blocking. the head and shoulder of the user from shifting laterally and away from the central support portion 11 due to the movement of the first inflatable air bag 13 during use of the neck support device S, in order to better fix the user's head and neck in such a position on the neck support device S, which corresponds to the first inflatable air cameo 13 and which is shown in FIG. 2 for reference, and by such fixation, also maintain the correct positioning of the user's shoulders relative to the neck support device S so that high-quality electrotherapeutic, thermotherapeutic and/or stretching effects can be provided. In some embodiments, at least one of the second inflatable airbags 19 has a flexible, flat top end that must face the upper interior surface of the respective second cavity 190, and a non-flexible or minimally expandable flat bottom base that is opposite the flat top end and must be facing the lower opening of the second cavity 190, and when the second inflatable air chamber 19 is inflated, the expansion ratio along the displacement axis of the flexible flat top end exceeds the expansion ratio of the inflexible flat bottom base. In some embodiments, when the second inflatable airbag 19 is inflated to expand to the second state of maximum expansion, the maximum height of the second inflatable airbag 19 in the direction of the displacement axis is from 6.5 cm to 10.5 cm or, in some embodiments, from 8 cm to 9 cm. However, the present invention is not limited to this. In addition, the maximum height of one of the second inflatable air chambers 19 may be the same as or different than the height of the other of the second inflatable air chambers 19, so that the user can be given a more versatile height adjustment of the different sides of the support device S. for the neck.

In addition, the introduction and positioning of the second inflatable airbags 19 in the structure(s) of the neck support device S may also allow a user who normally sleeps on their side, i.e., a side sleeper, to adjust the height and stiffness of the side regions of the neck support device S to necks on which a person sleeping on their side rests with the side of their head when lying on their side on the neck support device S. While the user of the neck support device S of the present invention who is accustomed to sleeping on his back, that is, the person sleeping on his back, can adjust the height and rigidity of the region of the neck support device S, which corresponds to the center support portion 11 and the first inflatable airbag 13 and the user's neck when he sleeps on his back, by inflating or deflated and changing the degree of expansion or contraction of the first inflatable airbag 13 in order to better support the cervical spine and restore the lordotic curvature of his cervical spine to a natural state, height adjustment and The stiffness of the central support portion 11 and the first inflatable airbag 13 may not be satisfactory in terms of head and neck support and alignment and support of the head, cervical spine and upper thoracic spine for a side sleeper who is more accustomed to lying on the side on the neck support device S and in the area of the neck support device S which is spaced from the central support part 11 and the first inflatable air chamber 13. Moreover, a person sleeping on his side may even more need additional head and neck support and restoring and maintaining the correct position of the spine, compared to people sleeping on the back, due to the fact that there is a greater vertical distance between the shoulder and the head / neck when the person is in the sleeping position on the side, for example, sleeping with the head laid on the side, than between the back and the head/neck when the person sleeping on their back is in the supine sleeping position. As also shown in FIG. 7 and 8, the neck support device S with the second inflatable airbags 19 provides the necessary additional support for the head and cervical spine and restores and maintains the correct position of the head, cervical spine and upper thoracic spine for the side sleeper, since the side sleeper can also adjust, in addition to the height and stiffness of the area of the neck support device S, which corresponds to the central support part 11 and the first inflatable air chamber 13, the height and stiffness of the side areas of the neck support device S, for example, areas of the upper surface the pillow body 1 and the upper surface of the pillowcase 2, which are adjacent to, respectively, the right and left sides of the pillow body 1 and the pillowcase 2, and are consistent with and can be displaced by the expansion or contraction of the second inflatable air chambers 19, when inflated or deflated, and changing the degree of expansion or contraction of the second inflatable air chambers 19 when the person sleeping on his side rests with the side of his head on these side regions of the neck support device S. When the second inflatable air bladder 19 is inflated, the second inflatable air bladder 19 may expand upwardly toward the side of the head, cervical spine, and upper thoracic spine of the user when the user is resting on their side and either side of the neck support device S, and causes the displaceable upper surface of the neck support device S, which corresponds to the second inflatable air bag 19, to move upward to straighten the head, cervical spine, and upper thoracic spine of the wearer. When the user inflates the second(s) inflatable(s) air(s) 19 to a level of height and softness/hardness that provide the desired adjustment for the user through the combined effects provided by the inflated(s) second(s)(- th) inflatable air chamber(s) 19 and the material(s) from which the support device S for the neck is made, and fixes the inflated second inflatable air chamber 19, the upper surface of the support device S for the neck, which corresponds to the inflated second airbag(s) 19, can comfortably conform to the contour of the sides of the head, cervical spine and upper thoracic region spine and align the head, cervical spine and upper thoracic spine of the user who sleeps on their side. That is, a side sleeper can adjust the height and stiffness of the area of the neck support device S, which supports the side of the head when he sleeps on his side, to provide a height and stiffness that he considers suitable for head and neck support, and maintain and restore alignment and neutrality of the head, cervical spine, and upper thoracic spine. However, the present invention is not limited to this. In addition, through the combined effects of an adjustable inflatable airbag 19 within an orthopedic shaped foam, such as an orthopedic shape memory foam, individually adjusted head and neck support for the wearer can be provided to keep the head, neck, and upper back in their natural anatomically neutral position. - an even position in order to avoid tension and pain when the user is resting on his side. Accordingly, with the features of the first inflatable airbag 13 and the second inflatable airbags 19 and their advantages, the neck support device S is suitable for both back and side sleepers as an everyday sleeping pillow.

As also shown in FIG. 7 and 8, the first inflatable air chamber 13 and the second inflatable air chambers 19 can respectively be connected with inflation devices 15 which are independent of each other. When the inflation device 15 is operating, it can inflate or deflate the first inflatable airbag 13 and the two second inflatable airbags 19 and change the expansion or contraction ratios of the first inflatable airbag 13 and the two second inflatable airbags 19. In some embodiments, the device 15 for inflation section includes at least one inflation section 151, a plurality of tubular portions 152, a first air valve 153, and a second air valve 155. The inflation section 151 may be a manual pressure pump for inflation. The tubular portions 152 may extend through the pillowcase 2 and the pillow body 1 to communicate with the first inflatable air chamber 13 and the two second inflatable air chambers 19, respectively, such that the inflation portion 151 may inflate or deflate the first and/or second inflatable air chambers 13, 19 through tubular portions 152. The first air valve 153 may be assembled with one of the tubular portions 152, and the tubular portion 152 may communicate with the first air chamber 13, and the second air valve 155 may be assembled with another tubular part 152 that communicates with the second inflatable airbags 19. However, the present invention is not limited to this. In some other embodiments, pumping section 151 may be an electric pumping pump, and in some embodiments, pumping device 15 includes a plurality of pumping sections 151. Each of the pumping stations 151 may be a manual pumping pump or an electric pumping pump. The first of the inflation sections 151 can be connected to at least one of the tubular parts 152 and communicate with the first inflatable air chamber 13 through the tubular part(s) 152 corresponding to the inflation section 151, which corresponds to and may communicate with the first inflatable air chamber(s) 13. The first air valve 153 may be assembled with one of the tubular parts 152 corresponding to the section 151 for pumping, which corresponds to and can communicate with the first inflatable air chamber(s) 13 The second of the inflation sections 151 can be connected to at least the other one of the tubular parts 152 and communicate with the second inflatable air chambers 19 through the tubular part(s) 152 corresponding to the inflation section 151, which corresponds to and can communicate with the second(s) inflatable(s) airbag(s) 19. That is, the section 151 for inflation, which inflates at least one of the second inflatable air chambers 19, may not depend on the section 151 for inflation, which inflates the first inflatable air chamber 13, while the sections 151 for inflation form an inflation control system that allows the user to separately control the respective sections 151 for inflation so that the degree of inflation of the first inflatable air chamber 13 can be adjusted by the user differently and independently of degrees of inflation of the second inflatable air chambers 19 via the inflation portions 151, since the necessary degree and time of inflation of the first inflatable air chamber 13 can be, and often is, different from those required for the second inflatable air chambers 19. The second air valve 155 may be assembled with one of the tubular parts 152 corresponding to the section 151 for pumping, which corresponds to and can communicate with the second(s) inflatable(s) air(s) chamber(s) 19.

As shown in FIG. 7 and 8, when the first air valve 153 is open, the inflation portion 151 can inflate or deflate the first air chamber 13. When the first air valve 153 is closed, the inflation portion 151 will not be able to inflate or deflate the first inflatable air chamber 13. Similarly, when second air valve 155 is open, inflation section 151 may inflate or deflate two second air chambers 19 at the same time. one inflation section 151, either an electric inflation pump or a manual inflation pump, is connected to the first inflatable air chamber 13 as well as to the second inflatable air chambers 19 to control the volume changes of the first inflatable air chamber 13 and the second inflatable air chambers 19 , control of the corresponding changes in the volumes of the air chambers can be performed by air valves on the pipe parts 152 corresponding to the air chambers 13, 19.

Although in FIG. 7 and 8, only a single second air valve 155 is shown to simultaneously adjust the inflation or deflation rates of the two second airbags 19, in some embodiments, two second air valves 155 may be provided to independently control the inflation or deflation ratios of either of the second airbags. 19. Additionally, in actual use, the user may open both the first air valve 153 and the second air valve 155 so that the inflation section 151 can simultaneously inflate the first inflatable air chamber 13 and the second inflatable air chambers 19. The user may also open the first air valve 153 and close the second air valve 155 to increase the inflation efficiency of the first inflatable air chamber 13. Similarly, the user can open the second air valve 155 and close the first air valve 153 to increase the inflation efficiency of the second inflatable air chambers 19. However, the present invention does this is not limited, and in some other embodiments, the inflation portions 151 corresponding to the first inflatable air chamber 13 and the second inflatable air chambers 19 may instead be a single electric inflation pump that can control inflation and/or deflation of the first inflatable air chamber 13 and/or second inflatable air chambers 19, respectively or simultaneously.

In other words, although in some embodiments, the neck support device S includes only one inflation portion 151, on which the air valve(s) can be used to direct airflow in and out of the first air chamber 13, which may be positioned under the neck of the wearer in the supine position, and may be adjusted to allow the air flow to the first air chamber 13 under the neck to be blocked and directed to the second air chambers 19 on both sides of the neck support device S, in some embodiments, in In the neck support device S, a plurality of inflation portions 151 can be applied such that one inflation portion 151 can direct air flow in and out of the first air chamber 13 under the neck of the user in the supine position, and the other inflation portion 151 can direct air flow in and out of the second air chambers 19 so that the pumping portions 151 operate independently of each other. Accordingly, the neck support device S may use a single inflation site system or a multiple inflation site system, and in some embodiments, in each system, the airflow in and out of the first air chamber 13 may still be separate from the airflow. in and out of the second air chambers 19, and inflation or deflation of the first air chamber 13 under the user's neck may still have no effect on the amount of air in the second air chambers 19, and inflation or deflation of the second air chamber(s) the chamber(s) 19 under the user's neck may still have no effect on the amount of air in the first air chamber 13. However, the present invention is not limited to this.

As shown in FIG. 1, 3 and 9, when the user's head is resting on the neck support device S, the first air chamber 13 can be inflated through the inflation portion 151. At the same time, the first air chamber 13 gradually expands so that the upper surface of the central support portion 11 gradually moves upward, thereby pushing the user's neck upward, and the user's cervical spine can return to its natural lordotic curvature and be presented in the form of an arc.
