When the side support plates 4 and the first adjustment plate 7 rotate relative to each other, the limit groove 36 contacts the surface of the limit rod 25 for limiting.

[0024] The angle adjustment mechanism includes a first driving device 15, the seat frame 5 is fixedly connected to a first mounting seat 18, the first mounting seat 18 is rotatably connected to the non-output end of the first driving device 15, the middle part of the adjustment branch pipe 22 is fixedly connected to a seat rotating seat 44, and the output end of the first driving device 15 is rotatably connected to the seat rotating seat 44; The leg support massage device includes a U-shaped massage side frame 29 and a side frame connector 31. The massage side frame 29 includes a telescopic rod 42 at the free ends on both sides. The side frame connector 31 is fixedly arranged with the massage connecting rod 28. One end of the fifth adjustment plate 26 is rotatably connected to the side frame connector 31, and the telescopic rod 42 is slidably arranged in the side frame connector 31.

[0025] The angle adjustment mechanism also includes a second driving device 16, the non-output end of the second driving device 16 is rotatably connected to a second mounting seat 19, the second mounting seat 19 is fixedly connected to one end of the U-shaped connecting frame 14, a backrest rotating seat 43 is fixedly connected to the middle part of the seat branch pipe 21, and the output end of the second driving device 16 is rotatably connected to the backrest rotating seat 43.

[0026] When in use, after the user sits on the load-bearing net 6, the user adjusts the position according to the user's own height conditions, starts the first driving device 15 and the second driving device 16, the output rod of the first driving device 15 extends, and the output rod of the second driving device 16 retracts. In this process, the supporting bottom member 3 and the side supporting plate 4 play a fixed supporting role. At this time, the first adjusting plate 7 rotates to one side, and the limiting groove 36 provided at one end of the first adjusting plate 7 rotates to one side. When the limiting groove 36 rotates to the set limit position, it will be stuck on the limiting rod 25, which is helpful to prevent the user from over-adjusting during use, resulting in an excessive opening and closing angle of the chair and causing the user to fall.
