When the user's buttocks apply pressure to the cushion module 40, the user's buttocks contact the fabric 43 and apply pressure to the sponge 42 to change the shape of the sponge 42 so that the fabric 43 fits the user's buttocks, thereby improving the comfort of the user's buttocks.

[0032] Please refer to the attached document. Figure 1 and 5In this embodiment, the portion of the fabric 43 connected to the connecting seat 41 serves as a connecting arm. This connecting arm is bonded to the side wall of the connecting seat 41 facing away from the sponge 42 using glue or double-sided adhesive. This allows the connecting arm to be fixedly connected to the side wall of the connecting seat 41 facing away from the sponge 42 by means of glue, preventing the glue from sticking to the sponge 42 and ensuring the performance of the sponge 42. Alternatively, the connecting arm is heat-pressed onto the side wall of the connecting seat 41 facing away from the sponge 42. This allows the connecting arm to be fixedly connected to the side wall of the connecting seat 41 facing away from the sponge 42 by means of heat pressing. The connecting arm extends along the outer contour of the peripheral side wall of the connecting seat 41 and is circumferentially connected to the connecting seat 41, so that the fabric 43 completely wraps around the sponge 42, ensuring the wrapping performance of the fabric 43 and the connecting seat 41 on the sponge 42.

[0033] Please refer to the attached document.

[0035] Alternatively, the connecting seat 41 is connected to the first support part 10 via a magic hook; so that the connecting seat 41 can be detachably connected to the first support part 10 via the magic hook, and when the magic hook is detached from the first support part 10, the seat cushion module 40 is in a detached state relative to the first support part 10.

[0036] Alternatively, the connecting seat 41 is connected to the first support portion 10 by screws, so that the connecting seat 41 can be detachably connected to the first support portion 10 by screws. When the screws are removed from the first support portion 10, the seat cushion module 40 is in a detached state relative to the first support portion 10.

[0037] Please refer to the attached document. Figures 1-4 In this embodiment, when the massage member 33 is a vibrating member 331, the vibrating member 331 is detachably connected to the mounting part 321 so that the vibrating member 331 can be connected to or detached from the mounting part 321. When the vibrating member 331 is connected to the mounting part 321, the vibrating member 331 is housed in the mounting part 321. The vibrating member 331 outputs vibration force in the working state and outputs the vibration force to the mounting part 321 to perform vibration massage on the user's waist, so that the user can perform vibration massage on the waist during use.

[0038] Please refer to the attached document. Figures 1-4 In this embodiment, the mounting part 321 is provided with a receiving groove 321a and an opening 321b, and the receiving groove 321a is connected to the opening 321b; the vibrating member 331 enters the receiving groove 321a through the opening 321b; so that the vibrating member 331 can be fixed inside the receiving groove 321a, thereby facilitating the fixation of the vibrating member 331 to the inside of the mounting part 321 through the receiving groove 321a, reducing the space occupied by the vibrating member 331 and the connecting member 32.

[0039] When the vibrating element 331 is in the receiving groove 321a, the inner sidewall of the receiving groove 321a elastically fits against the outer sidewall of the vibrating element 331, and the mounting part 321 positions and connects the vibrating element 331; so that the mounting part 321 restricts the range of motion of the vibrating element 331, ensuring the positional accuracy of the vibrating element 331 relative to the mounting part 321, avoiding the displacement of the vibrating element 331 relative to the user's waist, and ensuring the vibration output capability of the vibrating element 331 to the user's waist.

[0040] The diameter of the receiving groove 321a is larger than the diameter of the opening 321b to form an inverted structure with a larger inner diameter and a smaller outer diameter, preventing the vibrating element 331 from being directly pulled out from the opening 321b; the width of the vibrating element 331 is larger than the diameter of the opening 321b; the opening 321b is arranged in a long strip shape; the vibrating element 331 enters the opening 321b along an inclined direction and enters the receiving groove 321a through the opening 321b, so that the vibrating element 331 cannot be directly pulled out in a direction perpendicular to the opening 321b, ensuring that the vibrating element 331 is not easy to loosen or accidentally move out after installation; the vibrating element 331 is laid flat in the receiving groove 321a and is subjected to the positioning force of the mounting part 321; ensuring the positional accuracy of the vibrating element 331 and preventing the vibrating element 331 from shaking or shifting.

[0041] The portion of the mounting section 321 that forms the receiving groove 321a is recessed inward from the outer surface of the mounting section 321. The structural depth enhances the support for the vibrating element 331, improves reliability, and achieves reliable installation and anti-loosening of the vibrating element 331, while also providing ease of assembly and safety of use.

[0042] Please refer to the attached document. Figures 1-4In this embodiment, when the massage element 33 is a heating element 332, the heating element 332 is installed on the mounting portion 321 and covered by the metal housing 34. The heating element 332 outputs heat towards the metal housing 34 during operation, and the metal housing 34 heats the user's waist when it comes into contact with the user's waist. The heating element 332 has a connecting portion and a heating body. The connecting portion connects to the heating body, which faces the metal housing 34. The connecting portion is connected to the surface of the mounting portion 321, and the heating body is integrated into the connecting portion, outputting heat towards the metal housing 34 during operation. The metal housing 34 heats the user's waist when it comes into contact with the user's waist, thereby achieving a heated massage for the user's waist. This heated massage can relieve the user's lower back pain, improve local blood circulation, and enhance the comfort of the seat cushion assembly 100.

[0043] When the heating element 332 is a flexible circuit board module, the connecting part serves as the base of the flexible circuit board module and is attached to the surface of the mounting part 321; the heating body is integrated into the connecting part and serves as the heating part of the flexible circuit board module; to form a unified heating structure, the heating element 332 of the flexible circuit board module is relatively thin, which facilitates the use of the narrow space between the connecting part 32 and the metal housing 34, and reduces the space occupied between the connecting part 32 and the metal housing 34. Alternatively, when the heating element 332 is a heating plate, the connecting part serves as the bottom of the heating plate and is attached to the surface of the mounting part 321; the heating body is integrated into the connecting part and serves as the heating part of the heating plate; so that the first connecting part only undertakes the bottom support and attachment functions and does not directly participate in the circuit or signal transmission, thereby facilitating the heating body to be an independent heating layer.

[0044] Alternatively, when the heating element 332 is a heating wire, the connecting part serves as the connecting element 32 to which the heating wire is connected and is attached to the surface of the mounting part 321; the heating body is integrated into the connecting part and serves as the main body of the heating wire; the first connecting part is equivalent to a small adhesive pad, which is only responsible for sticking, welding and conducting heat to both ends of the heating wire; the heating body is equivalent to the heating wire itself, and the structure of the heating wire is extremely simple, the positioning is extremely accurate and the space occupied is extremely small.

[0045] The metal housing 34 is installed on the mounting part 321, and the heating element 332 is installed on the mounting part 321 and is covered by the metal housing 34. When the heating element 332 is in operation, it outputs heat toward the metal housing 34. When the metal housing 34 comes into contact with the user's waist, it heats the user's waist to achieve heating massage. Heating massage can relieve the user's waist pain and improve local blood circulation.

[0046] Please refer to the attached document. Figures 1-4In this embodiment, the massage module 30 further includes a circuit board 35 and multiple LED beads 36; the lumbar support 31 is provided with a receiving groove 31a and multiple light-emitting holes 31b, the multiple light-emitting holes 31b being connected to the receiving groove 31a along the thickness direction of the lumbar support 31; the circuit board 35 is housed in the receiving groove 31a and connected to the lumbar support 31; the multiple LED beads 36 are electrically connected to the circuit board 35 and distributed at different positions on the circuit board 35, the multiple LED beads 36 being arranged along concentric circles, a ring array, or a directional array; the multiple LED beads 36 are exposed to the corresponding light-emitting holes 31b, and the multiple LED beads 36 output light under the action of the circuit board 35 to provide phototherapy and heating effects to the user's back, so that the user's back can achieve phototherapy and heating effects, avoiding the situation where only the user's waist can be supported but not phototherapy and heating can be provided, thus enriching the functionality of the seat cushion assembly 100.

[0047] When multiple LED beads 36 are arranged concentrically, they form a multi-ring LED combination, which is arranged sequentially to address the varying heat flux requirements of different areas of the user's waist, thereby achieving a uniform heat field. Each LED bead 36 generates corresponding heat when emitting light, which is applied to the user's waist for heating and massage, creating a non-contact deep heat therapy and avoiding the risk of allergic reactions to the electrode gel.

[0048] In a multi-ring LED combination, the LED beads 36 in two adjacent rings are staggered to expand the range of phototherapy and heating of the user's waist by each LED bead 36, thus ensuring the phototherapy and heating effect of the multi-ring LED combination on the user's waist; or the LED beads 36 in two adjacent rings are arranged opposite each other, which improves the arrangement efficiency of the LED beads 36 in the two-ring LED combination.

[0049] In the second embodiment, a lumbar support chair includes a seat cushion assembly 100; the lumbar support member 31 of the seat cushion assembly 100 is detachably connected to the second support portion 20 of the seat cushion assembly 100, so that the lumbar support member 31 of the seat cushion assembly 100 can be connected to or detached from the second support portion 20. Optionally, the lumbar support member 31 of the seat cushion assembly 100 is detachably connected to the second support portion 20 by an elastic band; the sidewall of the lumbar support member 31 facing the second support portion 20 is fitted to the surface of the second support portion 20, ensuring the fit between the lumbar support member 31 and the second support portion 20.

[0050] The lumbar support 31 comprises a sponge layer and a leather layer. The leather layer is located outside the sponge layer and serves as the surface layer of the sponge layer, allowing the leather layer to wrap around the sponge layer and prevent the sponge layer from being lost. The leather layer has through holes, allowing the mounting part 321 to pass through the through holes and insert the leather layer. A connecting part connects to either the leather layer or the sponge layer, allowing the second connecting part to connect to the lumbar support 31 via the sponge layer or the sponge layer. The leather layer is harder than the sponge layer, achieving a functional layered structure of hard outside and soft inside, thus balancing protection, support, comfort, and durability. The leather layer prevents wear and tear during daily use. The relatively stiff leather layer is not easily deformed, maintaining the shape and contour of the lumbar support 31, providing a crisp appearance and preventing sagging.
