A lumbar support component

Abstract

This application relates to the technical field of lumbar health care devices, specifically to a lumbar support component, which includes a support portion having a first surface and a second surface facing away from each other. The first surface has a first accommodating cavity, and the second surface has an elastic support portion. The ratio of the width of the support portion along the first direction to the width of the human waist is i1, where 0.3 ≤ i1 ≤ 1.2, and the ratio of the length of the support portion along the second direction to the height of the human waist and back is i2, where 0.3 ≤ i2 ≤ 1.2. A quantitative adaptation model based on anthropometry is established to ensure that the size of the support portion accurately matches the lumbar support area of ​​users with different body types. The elastic support portion on the second surface directly conforms to the waist, increasing the area that can be flexibly deformed, and can effectively support the lumbar and back areas of different individuals, resulting in a better support effect. This effectively solves the problem that the use of lumbar support components in the prior art does not consider individual differences, leading to a poor experience for some users.

Description

Technical Field

[0001] This application relates to the technical field of lumbar health care devices, and more specifically, to a lumbar support. Background Technology

[0002] With the transformation of modern life and work patterns, prolonged periods of desk work, driving, and studying are becoming increasingly common. This places a continuous static load on the lower back, leading to a year-on-year increase in the incidence of conditions such as lumbar muscle strain and herniated discs. Therefore, devices that provide lumbar support have a significant market potential. However, existing lumbar support devices offer limited support and health benefits and cannot meet users' needs for proper support and health maintenance.

[0003] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0004] The purpose of this application is to overcome the shortcomings of the prior art and provide a new lumbar support to solve the problem that the health support effect of the existing lumbar support is limited and cannot meet the needs of users.

[0005] In a first aspect, some embodiments of this application provide a lumbar support member, which mainly includes a bearing portion. The bearing portion has a first surface and a second surface arranged opposite to each other. The first surface is configured with a first accommodating cavity, and the second surface is provided with an elastic support portion. The width of the coronal plane of the human body is defined as a first direction, and its length is defined as a second direction. The ratio of the width of the bearing portion along the first direction to the width of the human waist is i1, where 0.3≤i1≤1.2. The ratio of the length of the bearing portion along the second direction to the height of the human waist and back is i2, where 0.3≤i2≤1.2.

[0006] The first accommodating cavity allows for functional expansion and caters to the support needs of different users. Its design, combined with the elastic support section, generates corresponding support forces for different users. Furthermore, this ergonomically based quantitative adaptation model ensures that the dimensions of the supporting section precisely match the lumbar support area of ​​users with different body types. The elastic support section on the second side directly conforms to the waist, increasing the area of ​​flexible deformation and providing effective lumbar support for different body types, resulting in better support.

[0007] In some embodiments of this application, the elastic support portion is constructed with a smooth convex surface that adapts to the human lumbar region in a second direction. This smooth convex surface in the second direction precisely conforms to the physiological curvature of the lumbar spine, guiding the lumbar region to maintain a normal biomechanical posture through the mechanical transmission characteristics of the curved surface, thus reducing lumbar kyphosis compensation during prolonged sitting.

[0008] In some embodiments of this application, the smooth convex surface is adapted to the waist of the human body in a first direction. Further defining the smooth convex surface as adapted to the waist in the first direction, a three-dimensional curved surface fitting structure is formed.

[0009] In some embodiments of this application, the ratio of the width of the elastic support portion along the first direction to the width of the human waist is i3, where 0.2≤i3≤1.

[0010] In some embodiments of this application, the ratio of the length of the elastic support portion along the second direction to the length of the human lumbar vertebra is i4, where 0.5 ≤ i4 ≤ 1. This configuration allows the elastic support area to precisely cover the entire lumbar vertebrae or provide focused reinforcement of the lower lumbar spine. For segments with a high incidence of lumbar disc herniation, a longer elastic support portion can provide more continuous pressure relief on the nucleus pulposus.

[0011] In some embodiments of this application, the thickness of the elastic support is greater than or equal to 10 mm. This ensures that the material has sufficient compressive resilience.

[0012] In some embodiments of this application, the elastic support is integrally formed with the load-bearing portion. This eliminates the problems of complex assembly and inconvenient production associated with traditional splicing structures.

[0013] In some embodiments of this application, the second surface is configured with a second receiving cavity facing away from the first receiving cavity, and the volume of the second receiving cavity is smaller than that of the first receiving cavity. The structure of the second receiving cavity can accommodate other components, and the embedded design does not affect the flatness of the second surface.

[0014] In some embodiments of this application, the supporting portion is provided with a reinforcing member. The reinforcing member can enhance the bending stiffness of the supporting portion and prevent irreversible deformation of the lumbar support due to lumbar lordosis during prolonged sitting.

[0015] In some embodiments of this application, the reinforcing member is disposed within the first accommodating cavity. The reinforcing member does not require external installation, thus avoiding the need to occupy external space and increase the volume of the lumbar support member.

[0016] In some embodiments of this application, the middle part of the supporting portion is further provided with a smooth, tapered waist section. This allows it to fit the narrowest part of the human waist, making it convenient for the user to hold and place the lumbar support.

[0017] In summary, the technical solution of this application can effectively overcome the shortcomings of the prior art and provide a lumbar support, solving the problem that the use of lumbar support in the prior art does not take into account individual differences, resulting in a poor experience for some users.

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0029] The following disclosure provides numerous different embodiments or examples for implementing various structures of this application. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of this application. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0030] For ease of description, spatial relative terms may be used in the text to describe the relative position or movement of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "front," "back," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure undergoes a positional flip, orientation change, or change of motion, these directional indications will change accordingly. For instance, an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0031] In the description of this application, "multiple" means two or more.

[0032] It should be noted that existing lumbar support components use standardized dimensions and do not fully consider individual differences in anthropometry. Specifically, the width of the lumbar support is not well matched with the width of the human body in the coronal plane. When the support area is too narrow, it is difficult to effectively distribute the pressure concentration in the lumbar spine; when it is too wide, the lateral restraint force decreases, affecting the human body's freedom of movement in the sagittal plane. In terms of longitudinal dimensions, if the length of the support component cannot cover the key spinal area, it will significantly reduce the support efficiency for the thoracolumbar junction, while excessive extension will increase the burden of wearing and cause secondary discomfort. In addition, at the structural design level, the mechanical coupling relationship between the load-bearing part 1 and the elastic support part 121 in existing products has not been fully optimized. The rigid load-bearing structure is prone to stress concentration, while the flexible elastomer is difficult to provide continuous and stable support force, making it difficult to balance support stability and wearing comfort, and failing to meet the performance requirements of dynamic support in ergonomics.

[0033] To address the problem that existing lumbar support devices do not consider individual differences, resulting in a poor user experience for some users, an improvement to the lumbar support device technology is provided. The technical solution related to this application is illustrated below with reference to the accompanying drawings.

[0034] Please see Figures 1 to 4 In some exemplary embodiments of this application, a lumbar support member is provided, which mainly includes a support part 1. The support part 1 has a first surface 11 and a second surface 12 arranged opposite to each other. The first surface 11 is configured with a first accommodating cavity 111, and the second surface 12 is provided with an elastic support part 121. The width of the coronal plane of the human body is defined as the first direction X, and its length is defined as the second direction Y. The ratio of the width of the support part 1 along the first direction X to the width of the human waist is i1, 0.3≤i1≤1.2. The ratio of the length of the support part 1 along the second direction Y to the height of the human waist and back is i2, 0.3≤i2≤1.2.

[0035] For a detailed description of the coronal plane distribution, please refer to [reference needed]. Figure 5 As shown.

[0036] The first accommodating cavity 111 can accommodate the expansion of auxiliary functions and also match the support needs of different users. It can be used in conjunction with the elastic support part 121 to generate corresponding support force when used by different users.

[0037] This anthropometry-based quantitative adaptation model ensures that the dimensions of the support unit 1 are precisely matched to the lumbar support area of ​​users with different body types. The elastic support unit 121 on the second side 12 directly fits the waist, increasing the area that can be flexibly deformed, and can effectively support the lumbar region of different people, resulting in a better support effect.

[0038] The lumbar support component, through the elastic support part 121, ensures a close fit between the support and the lower back, achieving a stable and reliable lumbar support function. Simultaneously, the lumbar support component can also be functionally expanded through the first receiving cavity 111 on the first surface 11 to meet the different needs of various users, effectively improving support stability and structural flexibility.

[0039] It should be noted that the waist width of a human body refers to the overall width of the waist region in the projection of the human body onto the coronal plane. The waist width of an adult ranges from 18cm to 42cm, covering extremely thin or slender body types, normal body types, and overweight or obese body types. That is to say, the width of the bearing part 1 along the first direction X is between 5.4cm and 46.2cm.

[0040] The human lumbar height refers to the overall length of the lumbar region in the projection of the human body onto the coronal plane, ranging from 40cm to 73cm, covering people with a height of 1.4m to 1.9m. In other words, the length of the supporting part 1 along the second direction Y is between 12cm and 87.6cm.

[0041] In one embodiment, standard male anatomy parameters are used, with a waist circumference between 70.2cm and 78.2cm, and a waist width of 26cm as the median. A height of 175cm is used, and a back height between 58cm and 65cm is selected. Using a value of 0.65 ≤ i1 ≤ 0.75, the width of the supporting part 1 along the first direction X is between 16.9cm and 19.5cm, with a median of 18.2cm. The back height is selected with a value of 0.5 ≤ i2 ≤ 0.7, and a median back height of 61.5cm. Therefore, the length of the supporting part 1 along the second direction Y is between 30.75cm and 43.05cm, with a median of 36cm.

[0042] In one embodiment, standard female anatomy parameters are used, with a waist circumference between 62.7cm and 69.3cm. A waist width of 22cm can be taken as the median. A height of 162cm can be taken as a back height between 57cm and 64cm. Selecting 0.6≤i1≤0.65, the width of the supporting part 1 along the first direction X is between 13.2cm and 14.3cm, with a median of 13.42cm. Selecting 0.55≤i2≤0.65 for the back height, with a median back height of 60.5cm, the length of the supporting part 1 along the second direction Y is between 33.275cm and 39.325cm, with a median of 36.3cm.

[0043] In one embodiment, the width of the support portion 1 along the first direction X is between 24cm and 44cm, and the length of the support portion 1 along the second direction Y is between 36cm and 52cm.

[0044] In one embodiment, the width of the support portion 1 along the first direction X is 40cm, and the length of the support portion 1 along the second direction Y is 46.7cm.

[0045] In one embodiment, the width of the support portion 1 along the first direction X is 36cm, and the length of the support portion 1 along the second direction Y is 44cm.

[0046] In one embodiment, the preferred range for the ratio of the width of the support portion 1 along the first direction X to the width of the human waist is 0.5 ≤ i1 ≤ 0.9.

[0047] In one embodiment, the ratio of the width of the bearing portion 1 along the first direction X to the width of the human waist can be i1=0.4, i11=0.45, i1=0.5, i1=0.55, i1=0.6, i1=0.65, i1=0.7, i1=0.75, i1=0.9, i1=1.1 or i1=1.15.

[0048] In one embodiment, the preferred range for the ratio of the length of the support portion 1 along the second direction Y to the height of the human waist and back is 0.4 ≤ i2 ≤ 1.

[0049] In one embodiment, the ratio of the length of the bearing portion 1 along the second direction Y to the height of the human waist and back can be i2=0.4, i2=0.45, i2=0.5, i2=0.55, i2=0.6, i2=0.65, i2=0.7, i2=0.75, i2=0.9, i2=1.1 or i2=1.15.

[0050] In one embodiment, the first accommodating cavity 111 can be configured as an arch, with one arched side abutting against the second side 12. When the user lies down, the elastic support part is first squeezed. If the elastic support part is fully deformed and there is still a downward pressure, it can be further supported by the arched structure formed by the first accommodating cavity 111 to provide more support and achieve a better support effect.

[0051] Please see Figure 2 In some exemplary embodiments of this application, the elastic support 121 is constructed with a smooth convex surface 1211 that adapts to the waist of the human body in the second direction Y.

[0052] The smooth convex surface 1211 constructed in the second direction Y (coronal length direction) precisely conforms to the physiological curvature of the lumbar spine (the lordosis angle of the L3-L5 segment is approximately 15° to 20°). Through the mechanical transmission characteristics of the curved surface, it guides the lumbar region to maintain a normal biomechanical posture, reducing lumbar kyphosis compensation during prolonged sitting. This design directly acts on the lumbar and back contact interface, ensuring even distribution of support force across the core muscle groups such as the erector spinae and quadratus lumborum, resulting in a more significant support effect. Simultaneously, this structural design reduces the risk of localized stress concentration compared to traditional planar support structures, effectively extending the service life of the lumbar support component.

[0053] Furthermore, in some exemplary embodiments of this application, the smooth convex surface 1211 is adapted to the waist of the human body in the first direction X.

[0054] This design allows the smooth convex surface 1211 to conform to the lumbar region in the first direction X (coronal plane width direction), forming a three-dimensional curved conforming structure (adapting to the physiological characteristics of the human lumbar region, which has a left-right transverse diameter of approximately 15-20cm). This design effectively wraps around the transverse processes on both sides of the lumbar vertebrae, avoiding skin friction or muscle compression problems caused by rigid edge contact in traditional planar supports.

[0055] In some exemplary embodiments of this application, the ratio of the width of the elastic support portion 121 along the first direction X to the width of the human waist is i3, where 0.2 ≤ i3 ≤ 1. This configuration can adapt to the user's lumbar region, increase the softness of that area, facilitate better fit, provide a more suitable support range, and improve the user's comfort.

[0056] In one embodiment, the preferred range for the ratio of the width of the elastic support portion 121 along the first direction X to the width of the human waist is 0.6 ≤ i3 ≤ 0.8.

[0057] In one embodiment, the ratio of the width of the elastic support portion 121 along the first direction X to the width of the human waist can be i3=0.3, i3=0.35, i3=0.4, i3=0.55, i3=0.6, i3=0.65, i3=0.7, i3=0.75, or i3=0.85.

[0058] In some exemplary embodiments of this application, the ratio of the length of the elastic support portion 121 along the second direction Y to the length of the human lumbar vertebrae is i4, where 0.5 ≤ i4 ≤ 1.

[0059] The ratio i4 between the length of the elastic support section 121 and the length of the lumbar spine is limited to 0.5 ≤ i4 ≤ 1 (the length of the lumbar spine in adults is approximately 15-18 cm), ensuring that the elastic support area precisely covers the entire lumbar spine (L1-L5) or provides focused support to the lower lumbar spine (L4-L5, L5-S1). For the L4-L5 segment, where lumbar disc herniation is common, a longer elastic support section 121 (i4 close to 1) can provide more continuous pressure relief on the nucleus pulposus; while a shorter design (i4=0.5) is suitable for scenarios where lumbar flexibility needs to be preserved, achieving a differentiated adaptation between support strength and mobility.

[0060] In one embodiment, the preferred range for the ratio of the length of the elastic support portion 121 along the second direction Y to the length of the human lumbar vertebrae is 0.65 ≤ i4 ≤ 0.9.

[0061] In one embodiment, the ratio of the length of the elastic support portion 121 along the second direction Y to the length of the human lumbar spine can be i4=0.55, i4=0.65, i4=0.7, i4=0.75, i4=0.8, i4=0.85, i4=0.9, i4=0.95, or i4=1.

[0062] like Figure 4 As shown, in some exemplary embodiments of this application, the thickness of the elastic support portion 121 is greater than or equal to 10 mm.

[0063] The elastic support section 121 has a thickness of ≥10mm to ensure that the material (such as memory foam, latex, or elastic polymer) has sufficient compression and rebound performance. This thickness can absorb the impact energy generated by lumbar movement (such as the instantaneous pressure when changing sitting posture) and avoid insufficient support stiffness due to excessive thinness, which would affect the support effect.

[0064] It should be noted that the thickness of the elastic support portion 121 refers to the maximum dimension of the elastic support portion 121 protruding outward from the surface of the second surface 12. The thickness of the elastic support portion 121 gradually decreases in the middle and towards the second surface 12.

[0065] like Figure 4 As shown, in some exemplary embodiments of this application, the elastic support portion 121 is integrally formed on the load-bearing portion 1. This arrangement eliminates the problems of complex assembly and inconvenient production associated with traditional splicing structures.

[0066] In some embodiments, the carrier 1 may be made of a skin-friendly material, such as rubber, silicone, etc., or its surface may be covered with an integral skin material, such as leather, cloth, etc.

[0067] like Figure 4 As shown, in some exemplary embodiments of this application, the second surface 12 is configured with a second receiving cavity 122 facing away from the first receiving cavity, and the volume of the second receiving cavity 122 is smaller than that of the first receiving cavity 111. The structure of the second receiving cavity 122 can accommodate other components, and the embedded design does not affect the flatness of the second surface 12.

[0068] In some alternative embodiments, the second receiving cavity 122 communicates with the first receiving cavity 111 and can be used for the installation of other mating components.

[0069] like Figure 4 As shown, in some exemplary embodiments of this application, the support portion 1 is provided with a reinforcing member 13. The reinforcing member 13 can enhance the bending stiffness of the support portion 1 and prevent irreversible deformation of the lumbar support member caused by lumbar lordosis during prolonged sitting.

[0070] like Figure 4 As shown, in some exemplary embodiments of this application, the reinforcing member 13 is disposed within the first receiving cavity 111. The reinforcing member 13 (such as a metal strip, carbon fiber plate, or high-strength plastic) is disposed within the first receiving cavity 111 to avoid occupying external space and increasing the volume of the lumbar support member. Simultaneously, it can enhance the bending stiffness of the bearing portion 1 in the vertical direction, suppressing deformation of the support member caused by lumbar lordosis during prolonged sitting.

[0071] like Figure 4 As shown, in some exemplary embodiments of this application, the middle part of the support portion 1 is also provided with a smooth waist section.

[0072] The support section 1 features a smooth, tapered section in the middle, making it easy for users to pick up and put down the lumbar support. It can also adapt to the narrowest part of the human waist, forming an hourglass shape. This design can save on the volume and materials used in the lumbar support, reducing costs while making it easier for users to move around.

[0073] It should be understood that this application is not limited to the detailed structure and arrangement of the components proposed in this application. This application can have other embodiments and can be implemented and executed in various ways. The foregoing variations and modifications fall within the scope of this application. It should be understood that the disclosure and definition of this application extends to all alternative combinations of two or more individual features mentioned or apparent in the text and / or drawings. All these different combinations constitute multiple alternative aspects of this application. The embodiments described in this application illustrate the best known mode for implementing this application and will enable those skilled in the art to utilize this application.
