[0024] Compared with the prior art, the seat cover installation structure provided by the utility model makes the installation and removal of the cover 2 more convenient through the cooperation design of the first hook 32 and the first buckle hole 231 of the outer positioning plate 23, and the operation can be completed without professional tools. The cover 2 can be easily removed for cleaning or replacement, which helps to keep the seat clean and hygienic and extend the overall service life of the seat. The cooperation between the outer positioning plate 23 and the first hook 32 ensures the stability of the cover 2 during use, and avoids the cover 2 from loosening or falling off due to the movement of the user.

[0025] The seat cover installation structure provided by the utility model is suitable for different types of seats, and the appropriate material, color and pattern of the cover 2 can be selected according to specific needs to meet the needs of diverse decorative styles. Compared with the replacement of the entire seat, the cost of replacing only the cover 2 is lower, which provides users with an economical and efficient seat maintenance solution.

[0026] Specifically, there are four outer positioning sheets 23 arranged in a square shape, and the first hooks 32 are arranged in a square shape at intervals. In other words, the four outer positioning sheets 23 correspond to the positioning of the four directions of the front, back, left, and right of the surrounding edge portion 22 of the face cover 2, respectively, and each outer positioning sheet 23 is provided with a plurality of first buckle holes 231 arranged at intervals along its length direction, and the sheet metal frame 31 is provided with the same number of first buckle holes 231 and one-to-one corresponding first hooks 32, which evenly distribute the tension of the face cover 2, improve the stability of the face cover 2 on the seat, and prevent the face cover 2 from being loosened or deformed during use.

[0027] In this embodiment, the cushion portion 21 and the surrounding edge portion 22 of the face cover 2 are supported by cloth or leather, and the outer positioning piece is made of plastic. The plastic outer positioning piece body 23 has good toughness and can withstand a certain tensile force without being easily broken, thereby improving the durability of the entire face cover 2 structure, especially the outer positioning piece body 23 is not easily damaged during repeated disassembly and assembly. The outer positioning piece body 23 is connected to the surrounding edge portion 22 by sewing. Connecting the outer positioning piece body 23 to the surrounding edge portion 22 by sewing not only ensures the firmness of the connection part, but also simplifies the manufacturing process and reduces the production difficulty.

[0028] In order to improve the comfort of riding and reduce the discomfort caused by sitting for a long time, the sponge pad 12 will be designed according to ergonomics. In order to ensure that the cushion part 21 of the face cover 2 can be close to the surface of the cushion part 21, an inner positioning sheet 24 is provided inside the cushion part 21. The inner positioning sheet 24 can penetrate the sponge pad 12 and the part that passes through the sponge pad 12 is provided with a plurality of second buckle holes 241, that is, the sponge pad 12 is provided with a through hole 121 for the inner positioning sheet 24 to pass through and a second hook 33 for movable installation. The lower groove is connected to the through hole 121, and the seat plate 11 is provided with an avoidance hole 111 for the second hook 33 to pass through. The sheet metal frame 31 is provided with a plurality of second hooks 33 that cooperate with the second buckle holes 241. The matching design of the second buckle holes 241 and the second hooks 33 simplifies the installation process of the face cover 2, making the installation more convenient and eliminating the need for complicated tools. The inner positioning sheet 24 pulls the middle area of ​​the cushion portion 21 to fit tightly against the sponge pad 12, thereby preventing the face cover 2 from wrinkling or loosening during use.

[0029] If the cushion portion 21 of the face cover 2 is made of leather, a shaping seam line will be formed on the cushion portion 21 so that the cushion portion 21 converges and sinks toward the middle, and the shaping seam line in the middle extends horizontally and is connected to the inner positioning sheet 24 .

[0030] Similarly, the inner positioning sheet 24 is connected to the cushion portion 21 by sewing, and the sewing connection method ensures a firm connection between the inner positioning sheet 24 and the cushion portion 21, thereby improving the stability of the entire face cover 2 structure, especially being able to effectively resist the stress generated by the weight of the human body during use.

[0031] In order to facilitate the disassembly and assembly of the bottom shell 13, the bottom shell 13 is connected to the sheet metal frame 31 by snapping, and the sheet metal frame 31 is provided with a plurality of snap ears 34 snap-connected to the bottom shell 13, and the bottom shell 13 is provided with snap-connecting holes 131 matching with the snap ears 34. The matching of the snap ears 34 and the snap-connecting holes 131 ensures the tight connection between the bottom shell 13 and the sheet metal frame 31, and improves the overall structural stability of the seat. The snap-connecting design makes the installation and removal of the bottom shell 13 simpler and faster, without the need to use a screwdriver or other professional tools, reducing the difficulty of maintenance and cleaning, and improving the efficiency of disassembly and assembly.

[0032] In actual applications, the seat cushions of theater chairs and auditorium chairs have an automatic flipping function, that is, when the seats are not in use, the automatic flipping function can make the seat cushions upright, providing more space for pedestrians walking in the aisle, reducing the risk of collision and tripping; therefore, a laterally extending flip rod 41 is provided on the sheet metal frame 31, and the flip rod 41 is rotatably connected to the seat armrest, and a reset structure 42 is provided on the seat plate 11 for driving the seat plate 11 to flip and reset, and the reset structure 42 can be a counterweight positioning structure 42, a tension spring reset structure 42, etc., and the specific structure will not be elaborated.

[0033] To summarize, the disassembly process of the face cover 2 is as follows: the staff first presses the buckle ear 34 to separate the buckle ear 34 from the buckle hole 131 to remove the bottom shell 13, and then pulls the inner positioning sheet 24 to separate the second buckle hole 241 on the inner positioning sheet 24 from the second hook 33, and then pulls the outer positioning sheet 23 to separate the first buckle hole 231 on the outer positioning sheet 23 from the first hook 32 to release the fixation of the face cover 2, and finally pulls the face cover 2 and the sponge pad 12 to remove them.

[0034] On the contrary, the installation process of the face cover 2 is as follows: the inner positioning sheet 24 on the face cover 2 passes through the through hole 121 of the sponge pad 12, the surrounding edge 22 of the face cover 2 first covers the sponge pad 12 and then covers the seat plate 11, and then the first buckle hole 231 on the outer positioning sheet 23 is buckled on the first hook 32 of the sheet metal frame 31, and then the second buckle hole 241 on the inner positioning sheet 24 is buckled on the second hook 33 of the sheet metal frame 31, and finally the bottom shell 13 is installed.

[0035] The installation or disassembly process of the face cover 2 does not require the use of a screwdriver or other professional tools, which reduces the difficulty of maintenance and cleaning, and the disassembly efficiency is simple and efficient.
