And the pulling member 4 can be wound around the guiding bracket 38, thereby guiding and limiting the pulling member 4 through the guiding bracket 38, so that the force conduction direction of the pulling member 4 can be changed, which is convenient for the user to pull the pulling member 4 from different angles.

[0063] Furthermore, as Figure 2 shown, the guiding bracket 38 is provided with two side plates 381 having the same shape. In actual use, the two side plates 381 can also be set to have different shapes. And the two side plates 381 are arranged relatively spaced apart. The guiding bracket 38 is further provided with a limiting post 382. The limiting post 382 is arranged between the two side plates 381 and extends along the distribution direction of the two side plates 381. The limiting post 382 is rotatably connected between the two side plates 381. The limiting post 382 can be set as a pin, etc. And the pulling member 4 can be set as an annular pull belt. One end of the annular pull belt forms an annular structure and is sleeved on one end of the connecting rod 51 and is clamped into the installation groove 511 of the connecting rod 51. The other end extends out from the rear side of the seat backrest 3 and also forms an annular structure, which is convenient for the installation of the annular pull belt and the connecting rod 51 and convenient for the user to operate.

[0064] Meanwhile, the annular pull belt is wound around the limiting post 382, so that when the user pulls the annular pull belt, the friction between the annular pull belt and the limiting post 382 can be reduced, the service life of the annular pull belt can be prolonged, and the force applied by the user to pull the annular pull belt can be reduced, improving the user experience.
