[0033] The technical solutions in the embodiments (or "implementations") of this application will be clearly and completely described herein with reference to the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0034] If the embodiments of this application contain terms relating to directional indications or positional relationships (such as up, down, left, right, front, back, inside, outside, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, width, counterclockwise, clockwise, axial, radial, circumferential, etc.), such terms are only used to explain the relative positional relationships and movements between components in a specific posture (as shown in the attached figures); if the specific posture changes, the directional indications or positional relationships will also change accordingly. Furthermore, the terms "first" and "second" used in the embodiments of this application are only for descriptive convenience and should not be construed as indicating or implying relative importance.

[0035] The embodiments described in this specification will now be described in detail.

[0036] Reference Figure 1 As shown, this application discloses a seating arrangement including a base 10, a seat frame 20, a backrest 30, armrests 40, connectors 50, and a headrest 60. Each part is an independent module and uses a convenient connection method. Thus, the seating arrangement can be disassembled for transportation and storage, significantly reducing space occupation and lowering transportation difficulty and costs. When a component is damaged, only the corresponding module needs to be replaced, eliminating the need for complete replacement and reducing maintenance costs.

[0037] Please refer to the reference again. Figures 2 to 4As shown, the base 10 includes a crossbar 11, legs 12, mounting plate 13, and gas spring 14. The crossbar 11 is a metal tube composed of multiple tubes, with adjacent tubes not on the same straight line. Compared to a straight cylindrical tube, the overall structure of the tube in this embodiment has greater strength.

[0038] The support leg 12 is fixed to the middle of the crossbar 11. In this embodiment, the bottom of the crossbar 11 is provided with a threaded hole, and the support leg 12 is threadedly connected to the crossbar 11. In this way, the base 10 can be further disassembled, enhancing the portability and maintainability of the seating.

[0039] Mounting plates 13 are located at both ends of the crossbar 11. Mounting plates 13 are square plates with multiple threaded mounting holes. Mounting plates 13 and handrails 40 are fixedly connected through the threaded mounting holes. In other embodiments, mounting plates 13 and handrails 40 can also be connected by snap-fit ​​or pins, etc., to facilitate the assembly and disassembly of handrails 40 and base 10.

[0040] The fixed end of the gas spring 14 is connected to the crossbar 11, and the telescopic end of the gas spring 14 is connected to the seat frame 20. When the telescopic end of the gas spring 14 moves back and forth, it will cause the seat frame 20 to move synchronously, changing the state of the seat. Figures 3 to 4 This shows the seat switching from a sitting position to a reclining position.

[0041] The bottom of the seat frame 20 is provided with two connectors 50, which are located on both sides of the bottom of the seat frame 20. Specifically, the connectors 50 include a fixing plate 51 and a guide plate 52. The fixing plate 51 is fixed to the seat frame 20, and the guide plate 52 bends and extends from the mounting plate 13 toward the ground. The guide plate 52 is provided with a groove 21. By adding the connectors 50, the groove 21 is formed without damaging the structure of the seat frame 20. Moreover, when the groove 21 wears out later, only the connectors 50 need to be replaced, which is simple and convenient. In another embodiment, the groove 21 is directly set on the seat frame 20.

[0042] The slide rail 21 is inclined backward from top to bottom. Preferably, the inclination angle of the slide rail 21 relative to the horizontal ground is between 15° and 30° to balance the relationship between the seat height change and the reclining angle of the backrest 30. It should be noted that the reference plane for "up and down" here is the horizontal ground, and "backward" refers to the side closer to the backrest 30.

[0043] The front end of the guide plate 52 is smaller than the rear end. For example, the guide plate 52 is a trapezoid or wedge shape with a narrow front end and a wide rear end. This structure can significantly improve its bending and torsional stiffness. The extension and retraction direction of the gas spring 14 is parallel to the length direction of the slide groove 21, and the axial thrust direction of the gas spring 14 is completely consistent with the movement trajectory of the seat frame 20. This achieves efficient force transmission, minimizes wasted effort and friction loss, and makes it easy and effortless for users to adjust their sitting posture.

[0044] Please refer to the reference again. Figure 5 As shown, the backrest 30 is rotatably mounted on the rear end of the seat frame 20. The rear end of the seat frame 20 is provided with a rearwardly extending insert 22, and the lower end of the backrest 30 is provided with a notch 33, in which the insert 22 is rotatably placed.

[0045] Besides the engagement of the insert 22 and the notch 33, the rotatable connection between the backrest 30 and the seat frame 20 can also employ a hinge structure or a pivot structure. For example, connecting lugs with pivot holes can be provided on both sides of the rear end of the seat frame 20, and pivots can be provided at corresponding positions on the backrest 30. Inserting the pivot into the pivot hole will achieve a rotatable connection. To further limit the range of rotation, mechanical limit blocks can be provided at the notch 33 or the hinge to prevent the backrest 30 from tilting back excessively.

[0046] Two armrests 40 are mounted on the base 10 and are located on both sides of the seat frame 20 and the backrest 30, respectively. Each armrest 40 includes a body 43 and a connecting plate 44. The body 43 is placed outside the connecting plate 44 and covers the connecting plate 44. A first interface 41 and a second interface 42 are provided on the connecting plate 44.

[0047] In this way, on the one hand, the armrest 40 maintains a complete and simple appearance, effectively concealing the mounting port on the connecting plate 44 and enhancing the product's aesthetics and integration. On the other hand, this separate design allows the main body 43 to be independently replaced with armrest shells of different styles or materials without changing the internal structure, enhancing the product's personalization capabilities; the connecting plate 44, as an independent mounting frame, ensures the precision and strength of the connection with components such as the seat frame 20 and the backrest 30.

[0048] Considering that relying solely on a single connection point for installation between two modules results in significant installation freedom, is prone to cumulative errors, and suffers from insufficient connection stability, this application designs a system where one module is connected to at least two other modules, thus forming a stable over-constraint system. This multi-reference positioning method effectively restricts the displacement and rotational degrees of freedom of the module in all directions, significantly improving overall assembly accuracy and structural rigidity. For example, the armrest 40 is connected to the base 10, the seat frame 20, and the backrest 30.

[0049] Specifically, each armrest 40 includes a first interface 41 and a second interface 42. The side of the seat frame 20 is provided with a slide groove 21, and the first interface 41 is placed in the slide groove 21. The side of the backrest 30 is provided with a mounting hole 31 that rotatably engages with the second interface 42.

[0050] Please refer to the reference again. Figure 6 As shown, the bottom of the headrest 60 is provided with a plug rod 61, and the top of the backrest 30 is provided with a through hole, in which the plug rod 61 is placed. In this way, the headrest 60 can be disassembled without tools through a plug-in design, which can not only adjust the height, but also make it easy to disassemble and assemble, greatly reducing the packaging volume.

[0051] To allow for adjustment of the insertion and removal height of the headrest 60, a sleeve 32 is provided inside the through hole, and a slot 611 is provided on the insertion rod 61. The insertion rod 61 can move up and down within the sleeve 32, and after engaging with the sleeve 32 through the slot 611, the headrest 60 is positioned, which is beneficial for different height needs of different people and further enhances the seating experience.

[0052] Specifically, to achieve multi-level height adjustment, multiple annular slots 611 (or through holes) can be spaced axially on the insertion rod 61, while the inner wall of the sleeve 32 is equipped with elastic clips (such as spring steel balls). When height adjustment is required, the user pulls out or presses down the headrest 60 with slight force, causing the clips to disengage from the current slot 611. When the user slides to the desired height position of the slot 611, the clips automatically engage under the action of spring force, accompanied by a clear "click" sound, providing clear position feedback. This design achieves rapid and reliable stepless or stepped adjustment.

[0053] This application modularizes and integrates the various parts of the seating, thereby enhancing the product's portability and maintainability while ensuring its core functions. The assembly and disassembly process is simple and quick, and the application scenarios are more extensive. At the same time, it reduces production, transportation, and maintenance costs, giving it significant market competitiveness.

[0054] It should be noted that the technical solutions or features described in the above embodiments can be combined or supplemented with each other without conflict. The scope of protection of this application is not limited to the precise structures described in the above embodiments and shown in the accompanying drawings; all modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
