[0034] According to the embodiment of the present utility model, the seat 100 is improved in terms of adaptability and personalization by setting a detachable first support assembly 1 and a second support assembly 2, thereby enhancing the assembly flexibility of the seat 100. The seat 100 can be more widely used in various scenarios, enabling the seat 100 to better meet the needs of different user groups.

[0035] In some embodiments of this utility model, the chassis 3 includes: a fixed shell 31 and a tail plate 32. The tail plate 32 is located on the rear side of the fixed shell 31 and is rotatably connected to the fixed shell 31. The first support assembly 1 includes a first connecting rod 11. One end of the first connecting rod 11 is rotatably connected to the sliding rod 4 of the seat basin, and the other end of the first connecting rod 11 is connected to the tail plate 32. The armrest assembly is connected to the first connecting rod 11. Figures 1-4As shown, the chassis 3 and the backrest assembly are rotatably connected relative to each other via the tail plate 32. The tail plate 32 is connected to the rear side of the fixed shell 31, and the tail plate 32 and the fixed shell 31 can rotate relative to each other. The upper end of the first connecting rod 11 is rotatably connected to the sliding rod 4 of the seat basin, and the lower end of the second connecting rod 12 is connected to the tail plate 32. The armrest assembly is detachably connected to the first connecting rod 11. Therefore, the connection method between the chassis 3 and the first support assembly 1 is simple, reducing the difficulty of disassembly and assembly, and facilitating disassembly and assembly.

[0036] In some embodiments of this utility model, the first support assembly 1 further includes a second connecting rod 12, one end of which is rotatably connected to the sliding rod 4 of the seat basin, and the other end of which is rotatably connected to the fixed shell 31. The second connecting rod 12 and the first connecting rod 11 are arranged parallel to each other in the front-back direction. Figures 1-4 As shown, the upper end of the second link 12 is rotatably connected to the sliding rod 4 of the seat, and the lower end of the second link 12 is rotatably connected to the fixed shell 31. The second link 12 is located in front of the first link 11 and is arranged parallel to the first link 11, which increases the stability of the first support assembly and ensures the smooth movement of the seat in different postures. In short, the first support assembly 1, together with the seat and the chassis 3, forms a four-bar linkage mechanism, which is simple, stable, and easy to assemble and disassemble.

[0037] In some embodiments of this utility model, there are two first connecting rods 11, located on the left and right sides of the rear end of the chassis 3, respectively. There are also two second connecting rods 12, located on the left and right sides of the front end of the chassis 3, respectively. The ends of the first connecting rods 11 and the second connecting rods 12 are rotatably connected between the chassis 3 and the seat, allowing the seat to be movably positioned above the chassis 3 via the two first connecting rods 11 and the two second connecting rods 12. It is understood that having two first connecting rods 11 and two second connecting rods 12 ensures that changes in the seat's posture are smooth and coordinated, and also guarantees that the movement of the armrests on the left and right sides is coordinated and consistent.

[0038] In some other embodiments of this utility model, the first support assembly 1 is replaced by the second support assembly 2. The chassis 3 includes a fixed shell 31 and a tail plate 32. The tail plate 32 is located on the rear side of the fixed shell 31 and is rotatably connected to the fixed shell 31. The second support assembly 2 includes an armrest link 21. The first end of the armrest link 21 is rotatably connected to the sliding rod 4 of the seat. The second end of the armrest link 21 is connected to the tail plate 32, and the third end of the armrest link 21 is connected to the armrest assembly. Figures 5-11As shown, the chassis 3 and the backrest assembly are rotatably connected relative to each other via the tail plate 32. The tail plate 32 is connected to the rear side of the fixed shell 31, and the tail plate 32 and the fixed shell 31 can rotate relative to each other. The upper end of the armrest link 21 is rotatably connected to the sliding rod 4 of the seat basin, the lower end of the armrest link 21 is connected to the tail plate 32, and the front end of the armrest link 21 is connected to the armrest assembly. The armrest assembly and the armrest link 21 are detachable. Therefore, the connection method between the chassis 3 and the second support assembly 2 is simple, reducing the difficulty of disassembly and assembly, and facilitating disassembly and assembly.

[0039] In some embodiments of this utility model, such as Figures 5-11 As shown, the armrest link 21 includes a first link 211 and a second link 212. The first link 211 extends vertically, and the second link 212 extends horizontally. The lower end of the first link 211 is connected to the second link 212 near the chassis 3, and the upper end of the first link 211 is rotatably connected to the sliding rod 4 of the seat basin. A bushing 22 is provided between the first link 211 and the sliding rod 4. One end of the second link 212 is connected to the chassis 3, and the other end of the second link 212 is connected to the armrest assembly. Thus, the combination of the first link 211 and the second link 212 realizes the linkage between the armrest assembly and the backrest assembly. When the backrest assembly rotates backward, the armrest assembly rotates backward with the backrest assembly, improving the flexibility of the seat 100 and enhancing the user experience of the seat 100.

[0040] In some embodiments of this utility model, a connecting hole is formed at the lower end of the first rod 211, and the first rod 211 and the second rod 212 are connected by fasteners 5 passing through the connecting hole. Thus, connecting the first rod 211 and the second rod 212 with fasteners 5 not only ensures a secure connection between the first rod 211 and the second rod 212, but also provides flexibility, facilitating user disassembly and assembly. This allows users to quickly replace the first support assembly 1 and the second support assembly 2, enabling the seat 100 to be applied more quickly and widely in various scenarios.

[0041] In some embodiments of this utility model, the second support assembly 2 further includes a second connecting rod 12, one end of which is rotatably connected to the sliding rod 4 of the seat basin, and the other end of which is rotatably connected to the fixed shell 31. The second connecting rod 12 and the second rod 212 are arranged parallel to each other in the front-back direction. Figures 5-11 As shown, the upper end of the second connecting rod 12 is rotatably connected to the seat, and the lower end of the second connecting rod 12 is rotatably connected to the fixed shell 31. The second connecting rod 12 is located on the front side of the armrest connecting rod 21, and the second connecting rod 12 is arranged parallel to the first rod 211 of the armrest connecting rod 21, which increases the stability of the second support assembly 2 and also ensures the smooth movement of the seat in different postures. In short, the second support assembly 2, together with the seat and the chassis 3, forms a four-bar linkage mechanism, which is simple and stable in structure and easy to assemble and disassemble.

[0042] In some embodiments of this utility model, the armrest connecting rod 21 includes two rods, which are respectively located on the left and right sides of the rear end of the chassis 3. The second connecting rod 12 also includes two rods, which are respectively located on the left and right sides of the front end of the chassis 3. The two ends of the armrest connecting rod 21 and the two ends of the second connecting rod 12 are rotatably connected between the chassis 3 and the seat, so that the seat is movably positioned above the chassis 3 via the two armrest connecting rods 21 and the two second connecting rods 12. It is understood that having two armrest connecting rods 21 and two second connecting rods 12 ensures that changes in the seat's posture are smooth and coordinated, and also guarantees that the movement of the armrests on the left and right sides is coordinated and consistent.

[0043] In some embodiments of this utility model, the second link 12 of the first support assembly 1 is the same as the second link 12 of the second support assembly 2. It is understood that when replacing the first support assembly 1 and the second support assembly 2, only the first link 11 of the first support assembly 1 and the armrest link 21 of the second support assembly 2 need to be disassembled and replaced; it is not necessary to replace the second link 12 of the first support assembly 1 and the second link 12 of the second support assembly 2. This reduces production complexity, decreases the number of molds, thereby reducing manufacturing costs and improving production efficiency. Simultaneously, it makes it easier for users to replace the armrest function of the seat 100.

[0044] In addition, this reduces the number of parts to be disassembled, ensuring both the reliability and stability of the seat 100 and the flexibility of its adjustment, allowing the seat 100 to better meet the needs of different user groups.
