[0025] In addition, the technical features involved in different embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0026] Please refer to Figure 1 and Figure 2 As shown in and, an embodiment of the present utility model provides a seat 100, which includes a foot tube assembly 10, a first support assembly 20, and a seat back assembly 30. The foot tube assembly 10 includes a first foot tube 11 and a second foot tube 12 that are spaced apart along a first direction X, so as to form a space between the first foot tube 11 and the second foot tube 12. Two ends of the first support assembly 20 are detachably connected to the first foot tube 11 and the second foot tube 12 respectively, thereby fixing the first foot tube 11 and the second foot tube 12. The seat back assembly 30 is disposed between the first foot tube 11 and the second foot tube 12, and the seat back assembly 30 includes a first bracket 31, a flexible pad 32, and a second bracket 33, wherein two sides of the flexible pad 32 along the first direction X are respectively connected to the first bracket 31 and the second bracket 33. The first bracket 31 is detachably connected to the first foot tube 11, and the second bracket 33 is detachably connected to the second foot tube 12. Compared with the prior art structure in which the seat back assembly 30 directly connects and fixes the foot tube assembly 10, resulting in the seat back assembly 30 being unable to contract along the first direction X, in the seat 100 of the present utility model, the foot tube assembly 10 is fixed by the first support assembly 20. Therefore, after the seat back assembly 30 including the flexible pad 32 structure is detached from the foot tube assembly 10, it can contract along the first direction X, thereby reducing the volume of the seat back assembly 30. At the same time, the first support assembly 20 and the foot tube assembly 10 are detachably connected, so the volumes of the foot tube assembly 10 and the first support assembly 20 can also be further reduced, effectively reducing the volume of the seat 100 after disassembly and facilitating transportation.

[0027] It can be understood that the flexible pad 32 can at least contract or fold in the first direction X, so that after the seat back assembly 30 is disassembled, the first bracket 31 and the second bracket 33 can be brought closer together for storage to reduce the volume. In some embodiments, the flexible pad 32 includes, but is not limited to, flexible cloth, flexible woven rattan, flexible rope, flexible rope surface, elastic tendons, etc., or a splicing combination thereof.

[0028] In some embodiments, please refer to Figure 2, the first leg tube 11 includes a first front leg 111, a first armrest 112, and a first rear leg 113. Both ends of the first armrest 112 are respectively connected to the first front leg 111 and the first rear leg 113. The first leg tube 11 is generally in an inverted U-shaped structure, and the first armrest 112 generally forms the bottom of the U-shaped structure. The second leg tube 12 includes a second front leg 121, a second armrest 122, and a second rear leg 123. Both ends of the second armrest 122 are respectively connected to the second front leg 121 and the second rear leg 123. The second leg tube 12 is generally in an inverted U-shaped structure, and the second armrest 122 generally forms the bottom of the U-shaped structure. The first support assembly 20 includes a first support member 21 and a second support member 22. The two ends of the first support member 21 are respectively connected to the first front leg 111 and the second front leg 121, and the second support member 22 is respectively connected to the first rear leg 113 and the second rear leg 123. On the premise of ensuring the connection stability between the first support assembly 20 and the leg tube assembly 10, by arranging the first support member 21 and the second support member 22 substantially parallel to the first direction X, a certain space can be formed between the first support member 21 and the second support member 22, so that a plurality of seats 100 can be stacked and nested.

[0029] In some embodiments, please refer to Figure 2 , the first support member 21 is connected to the first front leg 111 and the second front leg 121 by bolts (not shown in the figure), and the second support member 22 is connected to the first rear leg 113 and the second rear leg 123 by bolts. By means of screwing, on the one hand, the connection stability between the first support member 21 and the first front leg 111 and the second front leg 121 can be ensured, and on the other hand, the first support member 21 and the first front leg 111 and the second front leg 121 can be made detachable for easy disassembly and transportation. In other embodiments, please refer to Figure 1 , the first support member 21 is connected to the first front leg 111 and the second front leg 121 by snap connections, and the second support member 22 is connected to the first rear leg 113 and the second rear leg 123 by snap connections. By means of snap connections, additional bolts for screwing can be reduced, thereby reducing the number of parts and improving the assembly efficiency.

[0030] In some embodiments, please refer to Figures 2 to 5The first leg tube 11 is provided with a first mounting hole 114 extending therethrough, and the first bracket 31 is provided with a first threaded hole 311 corresponding to the position of the first mounting hole 114 on the side facing the first leg tube 11. The seat 100 further includes a first fastener (not shown), which passes through the first mounting hole 114 from the side of the first leg tube 11 away from the first bracket 31 and is then screwed with the first threaded hole 311. During the screwing process, the first fastener exerts a pulling force on the first bracket 31 toward the first leg tube 11, so that the first bracket 31 moves closer to the first leg tube 11. The second leg tube 12 is provided with a second mounting hole 124 extending therethrough, and the second bracket 33 is provided with a second threaded hole 331 corresponding to the position of the second mounting hole 124 on the side facing the second leg tube 12. The seat 100 further includes a second fastener (not shown), which passes through the second mounting hole 124 from the side of the second leg tube 12 away from the second bracket 33 and is then screwed into the second threaded hole 331. During the screwing process, the second fastener exerts a pulling force on the second bracket 33 toward the second leg tube 12, thereby causing the second bracket 33 to approach the second leg tube 12. Under the action of the first fastener and the second fastener, the first bracket 31 and the second bracket 33 move away from each other in the first direction X, thereby stretching the flexible pad 32 to be in a straight state.

[0031] In some embodiments, see Figure 6 , along the first direction X, the width K1 between the first bracket 31 and the second bracket 33 and the width K2 between the first leg tube 11 and the second leg tube 12 satisfy: K1≤K2. By setting the distance K1 between the first bracket 31 and the second bracket 33 to be less than or equal to the width K2 between the first leg tube 11 and the second leg tube 12, the first bracket 31 and the second bracket 33 can have enough space in the first direction X to stretch the flexible pad 32 during the process of the first fastener being screwed to the first bracket 31 and the second fastener being screwed to the second bracket 33.

[0032] In some embodiments, the first bracket 31 and the first leg tube 11 form at least two connection positions. Through the above structure, the connection between the first bracket 31 and the first leg tube 11 can be made more stable, and the first bracket 31 and the first leg tube 11 can be prevented from rotating relative to each other at a single connection position. Similarly, the second bracket 33 and the second leg tube 12 form at least two connection positions. Through the above structure, the connection between the second bracket 33 and the second leg tube 12 can be made more stable, and the second bracket 33 and the second leg tube 12 can be prevented from rotating relative to each other at a single connection position.

[0033] In further embodiments, see Figures 2 to 5The number of the first mounting holes 114 is at least two, and at least one first mounting hole 114 penetrates through the first front foot 111 along the first direction X, and at least one first mounting hole 114 penetrates through the first rear foot 113 along the first direction X. The number of the first threaded holes 311 and the number of the first fasteners are the same as the number of the first mounting holes 114. By arranging the first fasteners on both the first front foot 111 and the first rear foot 113 to pass through the first mounting holes 114 and be screwed with the first threaded holes 311, the first bracket 31 can be more stably and firmly connected to the first leg tube 11. The number of the second mounting holes 124 is at least two, and at least one second mounting hole 124 penetrates through the second front foot 121 along the first direction X, and at least one second mounting hole 124 penetrates through the second rear foot 123 along the first direction X. The number of the second threaded holes 331 and the number of the second fasteners are the same as the number of the second mounting holes 124. By arranging the second fasteners on both the second front foot 121 and the second rear foot 123 to pass through the second mounting holes 124 and be screwed with the second threaded holes 331, the second bracket 33 can be more stably and firmly connected to the second leg tube 12.

[0034] In some embodiments, please refer to Figure 2 and Figure 5 The seat-back assembly 30 includes a seat cushion portion 30a and a backrest portion 30b which are connected to each other. The seat cushion portion 30a is connected to the first leg tube 11 and the second leg tube 12 of the leg tube assembly 10, and the backrest portion 30b extends in a direction away from the first leg tube 11 and the second leg tube 12. The seat 100 further includes a second support assembly 50 which is detachably connected to the end of the backrest portion 30b far from the seat cushion portion 30a. When the seat 100 is in normal use, the seat cushion portion 30a mainly supports the human buttocks, and the backrest portion 30b mainly supports the human back and neck. Since there is a certain distance between the distal end of the backrest portion 30b and the seat cushion portion 30a, and there are no other support components between the first bracket 31 and the second bracket 33, in order to enhance the support ability of the distal end of the backrest portion 30b, the second support assembly 50 is arranged at the distal end of the backrest portion 30b to be connected to the first bracket 31 and the second bracket 33 respectively.

[0035] In some embodiments, please refer to Figure 5, the second support assembly 50 includes a main body portion 51 and a telescopic portion 52. One end of the main body portion 51 is connected to one end of the telescopic portion 52, the other end of the main body portion 51 is connected to one of the first bracket 31 and the second bracket 33, and the other end of the telescopic portion 52 is connected to the other of the first bracket 31 and the second bracket 33; the telescopic portion 52 can telescopically move relative to the main body portion 51 along the first direction X. By setting the telescopic portion 52 to be able to telescopically move relative to the main body portion 51 in the first direction X, it is convenient for the main body portion 51 and the telescopic portion 52 to be assembled or disassembled with the first bracket 31 and the second bracket 33 conveniently. The main body portion 51 and the telescopic portion 52 apply opposite acting forces to the first bracket 31 and the second bracket 33 in the first direction X respectively, so that the first bracket 31 and the second bracket 33 tend to move away from each other to keep the flexible pad 32 in a stretched and straightened state.

[0036] In some embodiments, one of one end of the main body portion 51 and one end of the telescopic portion 52 is provided with a third threaded hole, and the other is provided with a stud, and the stud is threadedly connected to the third threaded hole. The telescopic portion 52 can rotate relative to the main body portion 51 to extend or shorten the length of the second support assembly 50 along the first direction X. For example, when the telescopic portion 52 rotates clockwise relative to the main body portion 51, the length of the second support assembly 50 elongates; when the telescopic portion 52 rotates counterclockwise relative to the main body portion 51, the length of the second support assembly 50 shortens.

[0037] The seat 100 according to the embodiment of the present invention includes a foot tube assembly 10, a first support assembly 20, and a seat back assembly 30. The foot tube assembly 10 includes a first foot tube 11 and a second foot tube 12 arranged at intervals along the first direction X; the first support assembly 20 is detachably connected to the first foot tube 11 and the second foot tube 12 respectively; the seat back assembly 30 is arranged between the first foot tube 11 and the second foot tube 12, and the seat back assembly 30 includes a first bracket 31, a flexible pad 32, and a second bracket 33. The flexible pad 32 is connected to the first bracket 31 and the second bracket 33 respectively. The first bracket 31 is detachably connected to the first foot tube 11, and the second bracket 33 is detachably connected to the second foot tube 12. The present invention fixes the foot tube assembly 10 through the first support assembly 20, and the first bracket 31 in the seat back assembly 30 is connected to the first foot tube 11, and the second bracket 33 is connected to the second foot tube 12, so that the first bracket 31 and the second bracket 33 stretch the flexible pad 32 in the first direction X to complete the assembly of the seat 100. When disassembling, since the first bracket 31 and the second bracket 33 are connected through the flexible pad 32, the first bracket 31 and the second bracket 33 can contract in the first direction X, thereby reducing the overall volume of the seat back assembly 30. And the first support assembly 20 can also be disassembled relative to the foot tube assembly 10. Therefore, the volume of the parts after the seat 100 is disassembled is greatly reduced, which is convenient for transportation.

[0038] The above are only embodiments of the present utility model, and thus do not limit the patent scope of the present utility model. Any equivalent structural or equivalent process transformation made by using the content of the specification and drawings of the present utility model, or directly or indirectly applied in other related technical fields, shall similarly be included within the patent protection scope of the present utility model.
