Abstract
Description
Technical Field
[0001] This invention relates to lumbar support technology, specifically to a lumbar support device that simulates the high and low position support of crossed hands while lying flat. Background Technology
[0002] In today's society, with the fast pace of life and changing work styles, prolonged sitting or engaging in single-posture activities has become the norm. This has led to a rising incidence of lumbar diseases, such as lumbar disc herniation and lumbar muscle strain, seriously affecting people's quality of life and physical health. As a vital support structure for the human body, the lumbar region plays a crucial role in maintaining balance, bearing body weight, and performing various movements. Therefore, effective support and protection for the lumbar region are of paramount importance.
[0003] Currently, lumbar support products on the market can be mainly divided into the following categories:
[0004] Hard lumbar supports / cushions: These products are typically made of materials such as memory foam, latex, or hard plastic, possessing a certain degree of shaping and support capabilities, such as the ventilated and massage-enhancing lumbar support foam disclosed in publication number CN204838765U. However, their shapes are mostly fixed arcs or wedges. Since the physiological curves of the lower back vary greatly from person to person, this fixed shape makes it difficult to perfectly conform to each user's lower back, resulting in a significant reduction in support effectiveness. More importantly, the support they provide is singular and rigid, lacking dynamic adaptability to the human lumbar muscles and spine. During prolonged use, this may actually cause excessive local pressure on the lower back, leading to discomfort and potentially exacerbating existing lower back problems.
[0005] Inflatable lumbar supports: A key feature of these products is their ability to inflate and deflate, allowing for adjustment of the support's firmness and providing a degree of adjustability, as seen in the inflatable lumbar support pad disclosed in publication number CN217835430U. However, their support principle still relies on a single air column or air bag, making it impossible to achieve precise pressure control over different areas and key points of the lower back. In practical use, it's difficult to provide targeted support based on the specific stress levels in different parts of the lower back, thus failing to meet the complex and varied needs for lumbar support.
[0006] Lumbar supports with massage function: These products add components such as vibration motors to basic support functions, attempting to relieve lower back fatigue through mechanical vibration massage. However, they are essentially still mechanical physical stimulation, a relatively simple stimulation method that cannot simulate the delicate touch and precise pressure of a natural massage from human hands. Moreover, there is a lack of effective coordination between the massage and support functions; they cannot synchronously adjust the support intensity and massage method according to the needs of the lower back in different states, making it difficult to achieve the ideal effect of relieving fatigue and protecting the lower back.
[0007] Furthermore, most existing lumbar support products are single-function, focusing only on one aspect such as support or massage, lacking a comprehensive solution. Moreover, their design rarely takes ergonomic principles into account, failing to perfectly conform to the human lumbar region and resulting in poor comfort during use. Summary of the Invention
[0008] The purpose of this invention is to provide a lumbar support device that simulates the cross-arm high-low position support while lying flat, in order to solve the problem that the existing lumbar support products have a fixed shape and cannot provide biomimetic support.
[0009] To achieve the above objectives, the present invention provides the following technical solution: a lumbar support device simulating a cross-arms high-low position support while lying flat, comprising a lumbar support and a flexible support base, wherein:
[0010] The lumbar support is configured as a wearable back panel structure that is fixed by Velcro, elastic straps or buckles. The inner contour of the wearable back panel structure is an adaptive curved surface with adjustable support curvature. The wearable back panel structure has an opening near the lower back of the human body, and the four corners of the outer side of the opening have strap buckles.
[0011] The flexible support base is configured as a targeted support structure embedded within the lumbar support opening and in direct contact with the lower back. This targeted support structure includes a strap assembly and a support body in the shape of crossed hands. The support body includes a first support unit and a second support unit, both of which are biomimetic hand-shaped supports with the head higher than the tail. The first and second support units are arranged individually or in combination and crosswise within the opening to accommodate unilateral or bilateral support. For unilateral support, a single support unit is placed in the opening corresponding to the left or right side area requiring support. For bilateral support, the first and second support units are arranged in a crosswise pattern of upper left and lower right or upper right and lower left within the opening, forming a crosswise support layout covering both sides of the lumbar spine.
[0012] Furthermore, the strap assembly covers and acts on the back of the lumbar support. The strap assembly includes an X-shaped fixing buckle, a strap body connected to each end of the X-shaped fixing buckle, and a damping slip buckle on the strap body. The strap serves two purposes: first, it restrains and stabilizes the entire flexible support base, preventing it from shifting when the body rolls or moves, ensuring that the support body (first support unit, second support unit) always fits the target lumbar region; second, it provides multi-dimensional adjustment capabilities. By sliding and locking the damping slip buckle at different positions, the user can precisely control the coverage of the support unit, achieving a wide range of adaptations to different body types (such as height and weight) and different support needs (such as overall support or unilateral pressure).
[0013] Furthermore, the lower end of the X-shaped fastener has a pressure head that protrudes towards the inside of the waist, and the end of the strap body away from the X-shaped fastener is connected to the strap buckles at the four corners of the back of the wearable back panel.
[0014] Furthermore, the first support unit and the second support unit include an outer support layer, an extension layer and an intermediate support layer arranged sequentially from the outer edge to the middle. The extension layer is an elastic skeleton structure that can be stretched laterally. By adjusting the width of the extension layer in the horizontal direction, the contact coverage area with the back can be changed.
[0015] Furthermore, airbags and soft silicone modules are arranged in an alternating array within the outer and middle support layers. By inflating and deflating the airbags in different areas and combining the different hardness / thickness of the soft silicone modules, the precise distribution and dynamic adjustment of the support pressure are achieved, which is used to simulate the soft touch and progressive pressure of the palms and knuckles when the hands are crossed for support.
[0016] Furthermore, the lower end of the damping slip is connected to the outer support layer of the first support unit and the second support unit. The damping slip slides along the strap body and locks in order to adjust the tightening force and traction angle on the support unit, thereby coordinating the control of its support height, fit and cross shape.
[0017] Furthermore, the airbag is connected to a miniature air pump and control module, allowing users to adjust the airbag pressure in real time via an external controller or smart device. Users can independently, in real time, and precisely adjust the pressure of each airbag via a wired or wirelessly connected external controller (such as a handheld remote control) or smart device, thereby achieving personalized and dynamic control of the support force distribution.
[0018] Furthermore, the soft silicone module is molded using a multi-hardness gradient composite material, with its distribution corresponding to the muscle groups and key stress points on both sides of the lumbar spine. For example, in its distribution design, based on ergonomic data, the high-hardness area (30-40A) is precisely aligned with the areas where the erector spinae muscles on both sides of the lumbar spine typically require reinforced support; the medium-hardness area (20-30A) is aligned with muscle groups such as the quadratus lumborum; and the low-hardness, high-compliance area (10-20A) is placed near the spinous processes of the lumbar spine and other key stress points that are sensitive to pressure or require avoidance of rigid pressure. The multi-hardness gradient design simulates the tactile changes of the human hand from the base of the palm (firmer) to the fingertips (softer). When the user changes posture or applies different pressures, the silicone areas of different hardness produce differentiated deformations and feedback, thus more realistically replicating the rich and subtle mechanical interactions of the human hand during support.
[0019] Compared with existing technologies, this invention provides a lumbar support device that simulates the high-low position of crossed hands while lying down. It deeply integrates bionic design with an adjustable support structure. Utilizing a combination of a bionic hand support body with a high head and low tail, zoned and controllable airbags / silicone modules, and strap components, it achieves dynamic, precise, and personalized lumbar support. In particular, it effectively simulates the combined mechanical effects of surface support and point pressure when a person's hands are crossed. Compared to traditional rigid, inflatable, or vibrating massage lumbar supports, it offers a more ergonomic support effect, greater comfort, stronger adaptability, and effectively prevents and alleviates lumbar strain. Specific technical effects include the following:
[0020] 1. Through its modular, cross-support unit design, along with a laterally expandable extension layer and independently adjustable airbags / soft silicone modules, it dynamically conforms to the waistline of users with different body types. Users can choose to use a single support unit or a cross-combination mode based on discomfort on one or both sides, achieving a personalized and precise fit from structure to function. This design allows the support to actively adapt to the human body, and it simulates the gentle enveloping feeling and progressive support provided by the natural posture of crossing one's arms.
[0021] 2. By controlling the inflation and deflation of airbags arranged in an alternating array within each support unit, and combining this with the layout of soft silicone modules of varying hardness, this device can provide real-time adjustable pressure distribution with varying degrees of softness and hardness for key areas such as the muscle groups on both sides of the lumbar spine and the area beside the spinous processes. This simulates the synergistic effect of the large-area support of the palm and the localized deep pressure of the finger joints when supporting with both hands, achieving progressive support from surface to point and from shallow to deep.
[0022] 3. By combining a wearable back panel with a flexible support base, the overall weight and structural volume are reduced to the minimum while ensuring stability, making it suitable not only for home bedrooms but also for use during lunch breaks in offices or clinical rehabilitation treatments.

[0029] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.
[0030] As attached Figure 1 To be continued Figure 2 As shown:
[0031] Example 1:
[0032] The present invention provides a lumbar support device that simulates the high and low position support of the hands crossed while lying flat, including a lumbar support 1 and a flexible support base 2.
[0033] 1. In one embodiment of the present invention, the lumbar support 1 is configured as a wearable back panel structure that is fixed by Velcro, elastic straps or buckles. The inner contour of the wearable back panel structure is an adaptive curved surface with adjustable support curvature. The wearable back panel structure has an opening near the lower back of the human body, and strap buckles 101 are provided at the four corners of the outer side of the opening.
[0034] 2. In one embodiment of the present invention, the flexible support base 2 is configured as a targeted support structure embedded in the opening of the lumbar support 1 and in direct contact with the lower back of the human body. The targeted support structure includes a strap assembly 3 and a support body in the shape of crossed hands. The support body includes a first support unit 201 and a second support unit 202. Both the first support unit 201 and the second support unit 202 are biomimetic hand-shaped supports with a high head and low tail. The first support unit 201 and the second support unit 202 are arranged individually or in combination and crosswise in the opening to adapt to unilateral or bilateral support. The strap assembly 3 covers and acts on the back side of the lumbar support 1. The strap assembly 3 includes an X-shaped fixing buckle 301, a strap body 302 connected to each end of the X-shaped fixing buckle 301, and a damping sliding buckle 303 provided on the strap body 302. The straps serve two purposes: firstly, they restrain and stabilize the entire flexible support base 2, preventing it from shifting during body rotation or movement, ensuring that the support body (first support unit 201, second support unit 202) always fits snugly against the target lumbar region; secondly, they provide multi-dimensional adjustment capabilities. By sliding and locking the damping buckles 303 at different positions, users can precisely control the coverage area of the support unit, achieving broad adaptability to different body types (such as height, weight, and build) and different support needs (such as overall support or unilateral pressure). The lower end of the X-shaped fixing buckle 301 has a pressure head protruding inward towards the lumbar support 1, and the end of the strap body 302 away from the X-shaped fixing buckle 301 is connected to the strap buckles 101 at the four corners of the back of the wearable back panel.
[0035] 3. In one embodiment of the present invention, the lower end of the damping slip buckle 303 is connected to the outer support layer 4 of the first support unit 201 and the second support unit 202. The damping slip buckle 303 slides and locks along the strap body 302 to adjust the tightening force and traction angle on the support unit, thereby coordinating the control of its support height, fit and cross shape.
[0036] Working Principle: Embodiment 1 provides a highly biomimetic and customizable lumbar support solution. Its core lies in dynamically simulating and replicating the optimal support posture of crossing one's arms to support the lower back, conforming to human biomechanics, through a combination of structural biomimicry and mechanical adjustment. In use, the user first wears and secures the lumbar support 1 to their lower back, then inserts the flexible support base 2 into the opening. Depending on whether the discomfort is unilateral or bilateral, the user can choose to place the first and second support units 202 individually or in a cross combination. Subsequently, by adjusting the damping hooks 303 on the strap assembly 3, the user can intuitively adjust the shape of the support until the most fitting and comfortable support is achieved. This embodiment, through its adjustable physical structure, provides stable and adaptive basic support for the lumbar spine in a lying position.
[0037] As attached Figure 1 To be continued Figure 3 As shown:
[0038] Example 2:
[0039] This embodiment is basically the same as the previous embodiment, except that the first support unit 201 and the second support unit 202 include an outer support layer 4, an extension layer 5 and an intermediate support layer 6 arranged sequentially from the outside to the middle. The extension layer 5 is an elastic skeleton structure that can be stretched laterally. By adjusting the width of the extension layer 5 in the horizontal direction, the contact coverage area with the back can be changed.
[0040] 1. In one embodiment of the present invention, airbags and soft silicone modules (not shown in the figure) are distributed in an alternating array within the outer support layer 4 and the middle support layer 6. By inflating and deflating the airbags in different areas and combining the different hardness / thickness of the soft silicone modules, the precise distribution and dynamic adjustment of the support pressure can be achieved, which is used to simulate the soft touch and progressive pressure of the palm and knuckles when the hands are crossed for support.
[0041] 2. In one embodiment of the present invention, the airbag is connected to a miniature air pump and a control module, allowing the user to adjust the airbag pressure in real time via an external controller or smart device. The user can independently, in real time, and precisely adjust the pressure of each airbag via a wired or wirelessly connected external controller (such as a handheld remote control) or smart device, thereby achieving personalized and dynamic control of the support force distribution.
[0042] 3. In one embodiment of the present invention, the soft silicone module is molded from a multi-hardness gradient composite material, and its distribution corresponds to the muscle groups and key stress points on both sides of the lumbar spine. For example, in the distribution design, based on ergonomic data, the high-hardness area (30-40A) is precisely matched to the parts of the erector spinae muscle belly on both sides of the lumbar spine that usually require reinforced support, the medium-hardness area (20-30A) is matched to muscle groups such as the quadratus lumborum, and the low-hardness, high-compliance area (10-20A) is arranged at key stress points that are sensitive to pressure or need to avoid rigid pressure, such as beside the spinous processes of the lumbar spine. The multi-hardness gradient design simulates the tactile change of the human hand from the palm heel (firmer) to the fingertips (softer). When the user changes posture or applies different pressures, the silicone areas of different hardness can produce differentiated deformation and feedback, thereby more realistically reproducing the rich and delicate mechanical interaction when the human hand is supporting itself.
[0043] 4. In one embodiment of the present invention, to further enhance the adaptability and safety of the support, a thin-film pressure sensor network is integrated between the airbag surface or soft silicone module of the outer support layer 4 and the middle support layer 6. This sensor network is electrically connected to the control module and is used to monitor and provide feedback on the pressure distribution and pressure value between the support unit and the contact surface of the human waist in real time.
[0044] Working Principle: Based on the adjustable mechanical structure provided in Example 1, Example 2 further introduces an actively adjustable biomimetic support mechanism. Compared to the basic physical fit of Example 1, this example enables precise control of the support pressure distribution. During use, in addition to mechanical adjustments, users can preset or adjust the pressure of each airbag via smart devices, allowing the support unit to not only conform to the body shape but also respond to the specific needs of different areas of the lower back. For example, when experiencing unilateral lower back pain, the pressure of the airbag on that side can be increased individually to simulate acupressure; when overall relaxation is needed, the pressure can be evenly reduced to simulate gentle hand support. This upgrades the device from an adaptive instrument to a smart, interactive, and personalized lumbar support solution, significantly improving the comfort, targeting, and rehabilitation potential of the support.
[0045] In conjunction with Embodiments 1 and 2 above, the present invention also proposes a method for using the above-mentioned simulated hand-crossed high-low position support device for lying flat, comprising the following steps:
[0046] Step 1: The user wraps and secures the lumbar support 1 around the back of the waist according to their individual waist size and preferred tightness. Usually, the lower edge of the lumbar support 1 is aligned with the iliac crest (upper edge of the pelvis) and secured with Velcro, elastic bands or buckles to ensure stable wear without pressure or slippage.
[0047] Step Two: Based on the current location of lower back discomfort and support needs (such as unilateral soreness, bilateral fatigue, or overall support), select the layout of the first support unit 201 and the second support unit 202:
[0048] Unilateral support: If only the left or right side of the waist needs to be supported, a single support unit (first support unit 201 or second support unit 202) is embedded into the affected side area within the opening of the lumbar support 1.
[0049] Bilateral cross support: To simulate the overall effect of hands crossed under the waist, two support units are inserted into the opening in a cross pattern (such as upper left and lower right or upper right and lower left layout) so that they cover both sides of the lumbar spine in a cross layout.
[0050] Step 3: Cover the back of the lumbar support 1 with the strap assembly 3 and connect its four ends to the strap buckles 101 at the four corners of the back of the lumbar support 1. Manually slide the damping buckles 303 on each strap to observe and feel the shape change of the support unit in the waist area. By adjusting the position of the buckles, the tightening force and traction angle of the straps on the support unit can be changed, thereby achieving adjustment of fit and wrapping.
[0051] Step 4: Actively adjust the biomimetic pressure distribution:
[0052] Initial pressure setting: The device's control module is connected to the miniature air pump via an external controller or smartphone. Users can select from preset modes (such as full support, unilateral acupressure, and dynamic circulation) or enter a custom mode.
[0053] Fine-tuning of airbag pressure: In custom mode, users can independently adjust the inflation and deflation of airbags in different areas within the support unit. For example:
[0054] Increase the pressure of the air sacs in the areas corresponding to the erector spinae muscles on both sides of the lumbar spine to provide stronger support.
[0055] Reduce the pressure of the air sac near the spinous process of the lumbar vertebrae to avoid excessive compression.
[0056] When you feel soreness on one side, increase the airbag pressure in the key part of the support unit on that side.
[0057] It is important to note that the biomechanical core of the simulated crossed-hand support effect described in this embodiment of the invention lies in the fact that the cross-arranged support units create a pair of opposing torques on both sides of the lumbar spine, which helps maintain the physiological curvature of the lumbar spine when lying flat and disperses pressure on the intervertebral discs. This biomimetic design is superior to uniform support on a single plane.
[0058] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
