Description

Technical Field

[0001] This invention relates to the field of bedding technology, and more specifically to a sleep support pillow for improving the distribution of body pressure when lying on one's side. Background Technology

[0002] Pillows, as tools to aid sleep, are formed by stuffing materials into pillowcases for comfort.

[0003] In daily sleep, sleeping on one's side is the most common sleeping position for most people. When the human body lies on its side, the head, neck, shoulders, waist, and legs will form a natural physiological difference. Traditional sleep pillows are mostly single-filling or simple height-low structure, which is difficult to accurately adapt to the pressure requirements brought about by this difference. This can easily lead to problems such as the neck side being unsupported and pressure concentration in the acromion area, resulting in uneven pressure distribution in various parts of the body. Long-term use can easily cause tension and soreness in the neck and shoulder muscles, and even affect the physiological curvature of the cervical spine, reducing sleep comfort. Therefore, developing a sleep support pillow that is specifically designed to improve the body pressure distribution when sleeping on one's side, and can achieve precise support for the head, neck, waist, and legs and even pressure distribution, has become an urgent need to solve the pain points of existing technologies.

[0019] The present invention will be further described below with reference to specific embodiments. However, those skilled in the art should understand that the detailed description given herein with reference to the accompanying drawings is for better explanation. The structure of the present invention necessarily exceeds the limited embodiments described herein. Some equivalent alternatives or common means will not be described in detail herein, but still fall within the protection scope of this application.

[0020] Figures 1-6 This is the preferred embodiment of the present invention, which is described below in conjunction with the accompanying drawings. Figures 1-6 The present invention will be further described below.

[0021] A sleep support pillow for improving body pressure distribution when lying on one's side includes a pillow body, which comprises a headrest portion 1, a lumbar support portion 2, and a leg support portion 3. The headrest portion 1 and the lumbar support portion 2 are movably connected by a first pull-out mechanism. The first pull-out mechanism includes two first columnar filling strips 7, one end of which is fixedly connected to the end of the lumbar support portion 2. The end of the headrest portion 1 is provided with two first inner holes 5, and the other ends of the two first columnar filling strips 7 are slidably disposed within the two first inner holes 5. The lumbar support portion 2 and the leg support portion 3 are movably connected by a second pull-out mechanism, which includes two first inner holes 5. Two columnar filling strips 8, one end of each of the two second columnar filling strips 8 is fixedly connected to the other end of the lumbar pillow 2. Two second inner holes 6 are provided in the leg pillow 3. The other ends of the two second columnar filling strips 8 are respectively slidably disposed in the two second inner holes 6. The supporting pillow body also includes a lumbar pad 4. The lumbar pad 4 is recessed in the middle and adapted to the lumbar pillow 2. The head pillow 1, lumbar pillow 2, leg pillow 3 and lumbar pad 4 all adopt a layered structure design, which is composed of two functional layers stacked along the thickness direction. The two functional layers are wrapped by an outer wrapping layer 15. The layers are fixedly connected by bonding, sewing or hot pressing processes.

[0022] Through the aforementioned structure, an integrated support design is achieved, providing segmented support for the head, waist, and legs, with adjustable overall length and even distribution of pressure during side sleeping. This precisely addresses the core pain points of traditional pillows, such as their inability to adapt to the physiological differences in side sleeping posture and uneven body pressure distribution. The headrest 1, lumbar support 2, and leg support 3 utilize built-in first and second pull-out mechanisms to freely adjust their overall length and spacing, flexibly adapting to the user's height, body type, and side sleeping position. This perfectly matches the physiological needs of people of different heights during side sleeping. The lumbar support 4 precisely conforms to the curve of the human waist, effectively supporting and filling the gaps in the lumbar region during side sleeping, maintaining the natural support of the lumbar spine. Combined with layered functional materials, this ensures stable support for key areas such as the head, waist, and legs, while also achieving even pressure distribution and rapid pressure release. This effectively avoids localized pressure and muscle tension in protruding areas such as the acromion, hip, and legs, significantly optimizing body pressure distribution during side sleeping. While improving sleep comfort, it comprehensively protects the healthy curvature of the cervical and lumbar spine.

[0023] like Figure 3 As shown, both first inner holes 5 and two second inner holes 6 are T-shaped, and the diameter of the two first inner holes 5 and two second inner holes 6 on the side away from the lumbar support 2 is larger than the diameter on the side closer to the lumbar support 2.

[0024] The above structure forms a sliding channel with a large end limiting and a small end guiding, which allows the first columnar filling strip 7 and the second columnar filling strip 8 to extend and retract smoothly. When stretched to the limit, the inner diameter changes to form a barrier to prevent them from coming off, ensuring that the headrest 1, waist pillow 2, and leg pillow 3 are stably connected and will not separate or fall apart during use.

[0025] like Figure 3 and Figure 5 As shown, the ends of the two first columnar filling strips 7 and the two second columnar filling strips 8 are all fixedly installed with limiting filling blocks 9. The diameters of the four limiting filling blocks 9 are equal to the larger diameters of the two first inner holes 5 and the two second inner holes 6, respectively. The ends of the four limiting filling blocks 9 are all provided with two pull grooves 12.

[0026] With the above structure, the limiting filler block 9 slides within the large end of the first inner hole 5 and the second inner hole 6 of the T-shape. When it reaches the limit position, it is stuck by the inner hole step to achieve anti-dislodgement and limiting. The pull groove 12 makes it easy for users to hold and stretch with their fingers, making it easier to adjust the length. At the same time, it keeps the filler strip full and prevents it from collapsing or deforming.

[0027] like Figure 4 and Figure 5 As shown, each of the two matching limiting filling blocks 9 is provided with a first connecting component. The first connecting component includes a first connecting strap 10 and a first button 11. One end of the first connecting strap 10 is fixedly connected to the end of one of the limiting filling blocks 9. The first connecting strap 10 is provided with a first buttonhole. The first button 11 is provided on the other limiting filling block 9 and is adapted to the first buttonhole.

[0028] The above structure locks the stretched and positioned filling blocks 9 together, so that the headrest 1, lumbar pillow 2, and leg pillow 3 can remain fixed when combined, thus forming a columnar support pillow. This achieves multiple functions and provides stable and continuous overall support, preventing support failure due to length rebound when lying on your side, and improving the reliability of use.

[0029] like Figure 1 , Figure 4 and Figure 5 As shown, the headrest 1 and the leg pillow 3 are provided with a second connecting component at their two ends that are far apart from each other. The second connecting component includes a second connecting strap 16 and a second button 17. One end of the second connecting strap 16 is fixedly installed at the end of the leg pillow 3. A second buttonhole is provided on the second connecting strap 16. The second button 17 is fixedly installed at the end of the headrest 1 and is adapted to the second buttonhole.

[0030] With the above structure, the second connecting strap 16 and the second button 17 can be used to tighten and fix the head and tail of the support pillow body, so that the head, waist and legs form a U-shaped whole, which can meet different usage needs. The connection is stable and will not fall apart at will. The overall support contour remains unchanged and the usage effect is good.

[0031] like Figure 4 As shown, a third connecting component is provided between the lumbar pillow part 2 and the lumbar pad part 4. The third connecting component includes multiple third connecting straps 18 and multiple third buttons 19. One end of each of the multiple third connecting straps 18 is fixedly disposed on the outer periphery of the lumbar pad part 4. Each of the multiple third connecting straps 18 is provided with a third buttonhole. Each of the multiple third buttons 19 is fixedly installed on the lumbar pillow part 2 and is adapted to the multiple third buttonholes respectively.

[0032] With the above structure, the lumbar support 4 can be detached. By disconnecting the third connecting strap 18 from the third button 19, the lumbar support 4 can be removed and placed on the user's waist to enhance lumbar support. The concave design in the middle of the lumbar support 4 can be freely adjusted to fit the user's waist curve, fill the gap when lying on the side, distribute lumbar pressure, and facilitate disassembly and cleaning, thus improving hygiene and convenience.

[0033] like Figure 3 As shown, the functional layer includes a basic support layer 13, which is specifically a high-density, high-elasticity sponge material.

[0034] The above structure provides a stable, strong, and non-deformable foundation for the support pillow, effectively supporting the weight of the head, neck, waist, and legs, avoiding muscle tension caused by excessive collapse, maintaining the natural physiological curve of the human body when lying on its side, and ensuring the support effect from the bottom up.

[0035] like Figure 3 As shown, the functional layer also includes a pressure dispersion layer 14, which is specifically a natural latex material.

[0036] Through the aforementioned structure, utilizing the high resilience, conformability, and pressure-relieving properties of natural latex, localized pressure is evenly distributed across the body, reducing pressure on prominent areas such as the acromion, hips, and legs. This alleviates the problem of concentrated pressure when lying on one's side, enhancing softness and comfort. like Figure 3 As shown, the outer wrapping layer 15 is specifically made of long-staple cotton material.

[0037] The above structure provides a soft, skin-friendly, breathable, sweat-absorbent, and non-irritating surface feel, conforming to the skin comfortably without pressure, enhancing the sleep experience, while firmly wrapping the internal functional layer to prevent layer displacement and extend the overall service life.

[0038] like Figure 2As shown, the first columnar filling strip 7, the second columnar filling strip 8, and the limiting filling block 9 are all double-layered, with PP cotton filling inside and fabric wrapping the outside of the filling body to form a complete filling core.

[0039] The above structure makes the pull-out filling part full and soft, ensuring smoothness during stretching and adjustment, and also allowing it to bend, making it easy to fold the headrest 1 and lumbar support 2 to ninety degrees. This facilitates the simultaneous and even support of the head, waist and legs, without any hard edges, pressure or hollow feeling, resulting in a natural transition and more comfortable overall support.

[0040] The working principle and usage process of this invention: In normal use, the first connecting strap 10 and the first button 11 lock and limit the filling block 9, which enables the headrest 1, waist pillow 2 and leg pillow 3 to be connected into a whole to form a columnar support pillow. The second connecting strap 16 and the second button 17 fix the head and tail of the support pillow, so that the support pillow forms a U-shaped whole, thereby realizing different support functions and having strong functional diversity.

[0041] When the user needs to achieve sleep support, the connection between the two first connecting straps 10 and the two first buttons 11 is released. The distance and overall length of the headrest 1, waist pillow 2, and leg pillow 3 are adjusted by the first pull-out mechanism and the second pull-out mechanism. The first columnar filling strip 7 and the second columnar filling strip 8 slide along the first inner hole 5 and the second inner hole 6 respectively. The T-shaped structure, together with the limiting filling block 9, achieves anti-slip limiting and avoids falling off.

[0042] Bend the headrest 1 at a 90-degree angle to facilitate support for the head and neck. Disconnect the third connecting strap 18 from the third button 19, and detach the lumbar support 4 from the lumbar pillow 2. It can then be placed directly on the lower back to provide lumbar support and fill the gap in the side-lying sleeping area. The overall support pillow adopts a layered structure. The high-density, high-elasticity sponge base support layer 13 provides stable support; the natural latex pressure dispersion layer 14 evenly distributes body pressure; the long-staple cotton outer wrapping layer 15 enhances skin-friendly comfort; and the first columnar filling strip 7, the second columnar filling strip 8, and the limiting filling block 9 are filled with PP cotton, which is soft and flexible, achieving segmented and even support for the head, waist, and legs, optimizing the distribution of body pressure during side-lying sleeping, protecting the physiological curvature of the cervical and lumbar spine, and improving sleep comfort.

[0043] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the protection scope of the present invention.
