Description

Technical Field

[0001] This utility model relates to the field of household products technology, and in particular to an anti-stiff neck airbag structure. Background Technology

[0002] An airbag pillow is a smart pillow that uses inflatable airbags as its core support unit. It embeds multiple independent and controllable airbag units within a flexible matrix, utilizing air pressure regulation technology to dynamically adjust the pillow's height, firmness, and shape. Most existing airbag pillows employ a zoned airbag design, adjusting height and firmness through independent inflation and deflation to improve sleep comfort. However, they generally suffer from unreasonable airbag layouts. Traditional designs often use airbags arranged in a single direction, lacking targeted support for the head and neck curves, resulting in uneven pressure distribution. The airbags are often similar in size and shape, making it difficult to simultaneously meet the needs of head support and neck contouring. Some products have excessively large airbag spacing, creating support blind spots and affecting overall stability. Furthermore, most airbag pillows have a single airbag movement direction, only allowing for vertical rise and fall, failing to adapt to the dynamic adjustments of the head and neck at multiple angles during sleep. Poor coordination between airbags can easily lead to localized pressure concentration, exacerbating muscle tension and increasing the risk of stiff neck. These structural defects limit the actual effectiveness of airbag pillows in precise posture correction and personalized support. Utility Model Content

[0003] The main purpose of this invention is to provide an anti-stiff neck airbag structure, which aims to optimize the airbag layout and provide a more comfortable experience in preventing stiff neck and snoring.

[0004] To achieve the above objectives, this utility model proposes an anti-stiff neck airbag structure, comprising:

[0005] A flexible base layer, wherein the surface of the flexible base layer is provided with adjacent head and neck regions;

[0006] Multiple airbags are provided, the airbags having a length direction, the head area has at least four airbags equidistantly arranged, the neck area has at least two airbags, and the length directions of the airbags in the head area and the airbags in the neck area are arranged perpendicularly.

[0007] In one possible implementation, the flexible base layer is further provided with side zones on both sides of the head and neck areas, and the side zones are also provided with airbags, and the length direction of the airbags in the side zones is consistent with that of the airbags in the head areas.

[0008] In one possible implementation, the maximum inflation height of the head region airbag is defined as A, the maximum inflation height of the neck region airbag is defined as B, and the maximum inflation height of the side region airbag is defined as C. <B<C。

[0009] In one possible implementation, the flexible base layer has a front and a back, the airbag is disposed on the front, and the back has a plurality of air vents corresponding to the plurality of airbags.

[0010] In one possible implementation, the flexible base layer is PT cotton.

[0011] This utility model's technical solution utilizes a soft PT cotton base layer, with airbags divided into head, neck, and side zones on the front. The V-shaped indentation created by the height difference in airbag inflation automatically corrects head position, preventing stiff neck. The directional layout of the airbags, combined with unidirectional support in the side zones, provides dual protection: cervical spine support when lying supine and prevention of lateral tilting when lying on one's side. The independent air vent design on the back allows for precise inflation and deflation adjustment. Combined with the breathability and elasticity of the PT cotton, it provides a zero-pressure fit while maintaining structural stability. The intelligent system dynamically adjusts the airbag pressure in conjunction with sleeping posture. Its modular design offers advantages such as easy maintenance and low cost, effectively preventing stiff neck caused by poor sleeping posture, and is suitable for both daily and medical scenarios.

[0018] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0020] Reference Figures 1 to 2 This utility model proposes an anti-stiff neck airbag 2 structure, including a flexible base layer 1 and multiple airbags 2. The surface of the flexible base layer 1 is provided with adjacent head area 11 and neck area 12. The airbags 2 have a length direction, and the head area 11 is provided with at least four airbags 2 at equal intervals, and the neck area 12 is provided with at least two airbags 2. The length directions of the airbags 2 in the head area 11 and the airbags 2 in the neck area 12 are arranged perpendicularly.

[0021] Understandably, the soft base layer 1 serves as the foundation layer, using soft materials such as memory foam or fabric to ensure comfort. Its surface is divided into two functional zones: the head zone 11 supports the head and has at least four airbags 2, while the neck zone 12 supports the neck and has at least two airbags 2. In this example, the head zone 11 airbags 2 have a length direction AA, and the neck zone 12 airbags 2 have a length direction BB, perpendicular to each other; that is, the neck zone 12 airbags 2 are arranged laterally, and the head zone 11 airbags 2 are arranged longitudinally. This vertical design allows for multi-directional pressure adjustment; the head zone 11 airbags 2 control the left and right roll of the head, while the neck zone 12 airbags 2 adjust the height angle of the neck.

[0022] All airbags 2 require external pipes or valves to connect to the air pump, allowing independent control of the inflation and deflation of each airbag 2 to dynamically adjust head and neck posture. When an airbag 2 inflates, it raises the corresponding area; for example, inflating the left head area airbag 2 (11) tilts the head to the right, while deflating the neck area airbag 2 (12) lowers the support height. By combining and controlling different airbags 2, improper head tilting, backward tilting, or lateral neck bending during sleep can be corrected, reducing the risk of stiff neck and preventing snoring. It should be noted that the above functions require external sensors such as pressure sensors, gyroscopes, and sound sensors to monitor head and neck position in real time. For example, if supine snoring is detected, the system inflates the head airbag 2 to turn the head to the side and open the airway; if excessive neck bending is detected, the airbag 2 pressure is adjusted to restore the natural curvature.

[0023] The design advantages of this embodiment are: precise zone control, independent operation of head and neck zones with multiple airbags 2, flexibly adapting to different body types and sleeping positions; the vertical orientation of the head zone 11 and neck zone 12 airbags 2 can enhance multi-dimensional support for the head and neck.

[0024] refer to Figures 1 to 2 In one embodiment of this application, the flexible base layer 1 is further provided with side areas 13 on both sides of the head area 11 and the neck area 12. The side areas 13 are also provided with airbags 2, and the length direction of the airbags 2 in the side areas 13 is consistent with that of the airbags 2 in the head area 11.

[0025] Understandably, with traditional pillows, the head and neck are prone to tilting due to lack of support when sleeping on one's side, leading to muscle strain or cervical misalignment and causing a stiff neck. The 13 side-zone airbags provide extra support when the user is lying on their side, maintaining the natural alignment of the head, neck, and spine. Whether lying on their back or side, the 13 side-zone airbags dynamically adjust the pressure distribution, reducing localized pressure.

[0026] The side zone 13 airbags 2 and the head zone 11 airbags 2 are arranged in the same direction, ensuring that the mechanical direction of the head and lateral support airbags 2 is unified, avoiding discomfort caused by misalignment. When lying on one's side, the head zone 11 and side zone 13 airbags 2 work together to support the head and prevent lateral bending of the neck. The neck zone 12 airbag 2 maintains directional support for the cervical spine, forming a "cross-grid" structure with the head zone 11 / side zone 13, improving overall stability.

[0027] refer to Figures 1 to 2 In one embodiment of this application, the maximum inflation height of the airbag 2 in the head region 11 is defined as A, the maximum inflation height of the airbag 2 in the neck region 12 is defined as B, and the maximum inflation height of the airbag 2 in the side region 13 is defined as C. <B<C。

[0028] Understandably, the cervical region airbag 12 (airbag 2) is higher because the cervical spine needs stronger support to maintain its physiological curvature. When lying supine, the cervical region airbag 12 (airbag 2) is slightly higher than the head region airbag 11 (airbag 2) to prevent the neck from being unsupported due to excessive height. The lateral region airbag 13 (airbag 2) is the highest because the head sinks deeper when lying on one's side, requiring additional height compensation. The head region airbag 11 (airbag 2) is the lowest because the weight distribution of the head needs to be even; if it is too high, it will cause the cervical spine to flex forward.

[0029] The head region 11 is the lowest, the neck region 12 is slightly higher, and the lateral regions 13 are the highest, forming a V-shaped profile that is low in the center and high on both sides. When the head is placed in the head region 11, the lateral regions 13 on both sides and the lower neck region 12 form a surrounding limiting structure, keeping the head naturally centered and preventing excessive tilting. The V-shaped concave ramp structure generates a restoring force when the head tilts to the side, prompting the head to return to the midline position, effectively preventing stiff neck.

[0030] refer to Figures 1 to 3 In one embodiment of this application, the flexible base layer 1 has a front side 14 and a back side 15, the airbag 2 is disposed on the front side 14, and the back side 15 has a plurality of air vents 151 corresponding to the plurality of airbags 2.

[0031] Understandably, the soft base layer 1 can be made of memory foam, silicone, or flexible fabric. It consists of a front 14 and a back 15. The front 14, facing the head and neck, has multiple airbags 2. These airbags 2 can be embedded in or adhered to the surface of the base layer to ensure comfortable support. The back 15, away from the body, has air vents 151 corresponding to the position of each airbag 2. These vents connect to air supply tubes to supply or release air to the airbags 2. The air supply tubes are connected from the back 15 to avoid the tubing on the front 14 interfering with sleep comfort and reducing friction or pressure, unlike the internal stitching of traditional pillows which may cause discomfort to the head.

[0032] refer to Figures 1 to 3 In one embodiment of this application, the flexible base layer 1 is PT cotton.

[0033] Understandably, using PT cotton to make the soft base layer 1 has the following advantages: high softness; PT cotton is soft and can conform to the curve of the head and neck, reducing pressure. When combined with airbag 2, it can dynamically adapt to different sleeping positions and enhance the wrapping effect of the V-shaped indentation; good support and resilience; compared with the slow rebound of memory foam, PT cotton provides more immediate elastic support, preventing the head from sinking too much. It is not easy to collapse after long-term use and maintains the original height difference of the airbag 2 structure; high cost-effectiveness; PT cotton is a cost-effective synthetic fiber, suitable for mass-market product applications, easy to process and cut, and highly compatible with the assembly process of airbag 2.

[0034] This utility model's technical solution utilizes a soft PT cotton base layer 1, with 14 sections on the front panel featuring head zone 11, neck zone 12, and side zone 13 airbags 2. The V-shaped indentation formed by the height difference of the inflated airbags 2 automatically corrects head position, preventing stiff neck. The directional layout of the airbags 2, combined with the unidirectional support of the side zone 13, provides dual protection: cervical spine support when lying supine and prevention of lateral tilting when lying on one's side. The independent air vents 151 on the back support precise inflation and deflation adjustment. Combined with the breathability and elasticity of the PT cotton, it provides a zero-pressure fit while maintaining structural stability. The intelligent system can dynamically adjust the pressure of the airbags 2 in conjunction with sleeping posture. Its modular design offers advantages such as easy maintenance and low cost, effectively preventing stiff neck caused by poor sleeping posture, and is suitable for daily and medical scenarios.
