[0027] In this embodiment, the third limiting component 7 and the second limiting component 6 have the same structure, and the rotation center 1 provides installation conditions for the backrest 2, the first cushion 3 and the second cushion 4. When the backrest 2 needs to be rotated, the limitation of the backrest 2 is released by the two first limiting components 5, and the backrest 2 is rotated along the rotation center 1 to the side close to the first cushion 3, so that the backrest 2 can be folded. The limitation of the first cushion 3 is released by the second limiting component 6, and the first cushion 3 is rotated along the rotation center 1 to fold the first cushion 3. The limitation of the second cushion 4 is released by the third limiting component 7, and the second cushion 4 is rotated along the rotation center 1 to fold the second cushion 4. The utility model can realize separate adjustment of the backrest 2, the first cushion 3 and the second cushion 4 through the setting of the rotation center 1, thereby solving the problem that the seat cushion is a one-piece structure and the seat must be lifted as a whole when it needs to be lifted.

[0028] Furthermore, the backrest 2 includes a back plate 8 and an armrest assembly 9, the back plate 8 is rotationally connected to the rotation center 1, and is rotationally connected to the first seat cushion 3, and is rotationally connected to the second seat cushion 4, and the armrest assembly 9 is arranged on the back plate 8.

[0029] In this embodiment, the back panel 8 provides installation conditions for the armrest assembly 9, and the armrest assembly 9 can support the user's hands to improve the user's usage experience.

[0030] Furthermore, the armrest assembly 9 includes two rotating frames 10, two limit blocks 11 and an armrest body 12, the back panel 8 has two slide grooves 20, the two rotating frames 10 are respectively rotatably connected to the back panel 8 and are both located on the back panel 8, the two limit blocks 11 are respectively fixedly connected to the two rotating frames 10 and are respectively located in the two slide grooves 20, and the armrest body 12 is fixedly connected to the two rotating frames 10 and is located on the two rotating frames 10.

[0031] In this embodiment, when the armrest body 12 needs to be used, the armrest body 12 is rotated to the side away from the back panel 8, and the armrest body 12 drives the two limit blocks 11 on the two rotating frames 10 to slide in the two sliding grooves 20 until the armrest body 12 is rotated to the preset position, and the armrest body 12 can be unfolded.
