[0016] The present invention will be further described below with reference to the accompanying drawings.

[0017] like Figures 1 to 5 A foldable training chair includes a chair frame 1, a seat 2, and a backrest 3. The chair frame 1 has the seat 2 and backrest 3. The bottom of the seat 2 has two flip seats 4 and two limiting seats 5. The flip seat 4 includes a base 6 and a connecting plate 7. The bottom of the base 6 is connected to a connecting groove 8 and a limiting groove 9. The connecting plate 7 has a sliding groove 13 and a second fixing hole 14. The center of the connecting groove 8 has a first fixing hole 10. Bolts 15 are used to fix the connecting plate 7 and the base 6 through the second fixing hole 14 and the first fixing hole 10 in sequence. The lower end of the limiting seat 5 has a container. The receiving slot 16 and the chair frame 1 include two front chair legs 17, two rear chair legs 18, a flip rod 19 and a support rod 20. The two rear chair legs 18 are connected to the two front chair legs 17 through the support rod 20. One end of the support rod 20 abuts against the receiving slot 16. The flip rod 19 passes through the flip seat 4. Both ends of the flip rod 19 are fixedly connected to the support rod 20. The flip rod 19 has a protrusion corresponding to the sliding groove 13. The flip rod 19 moves along the sliding groove 13. Each of the two rear chair legs 18 has a crossbar 21 at its upper end. The crossbar 21 is connected to the chair back 3.

[0018] The seat 2 includes a hip support area 22 and a leg support area 23. The hip support area 22 is connected to the leg support area 23 on one side. The other three sides of the hip support area 22 are curved upwards, and the outer edge of the leg support area 23 is curved downwards, which improves the comfort of sitting for a long time.

[0019] The backrest 3 has several ventilation holes to increase air circulation and improve the breathability of the seat.

[0020] The flip seat 4 is fixedly connected to the seat 2 by fasteners.

[0021] The connecting plate 7 includes a straight section 11 and an arc section 12. The two ends of the arc section 12 are connected to the straight section 11. The inner side of the arc section 12 is provided with a sliding groove 13. The straight section 11 of the connecting plate 7 is provided with a fixing hole 14. The straight section 11 of the connecting plate 7 abuts against the connecting groove 8 of the base 6. The arc section 12 of the connecting plate 7 and the limiting groove 9 of the base 6 form a rotating cavity.

[0022] The bottom of the front chair leg 17 and the rear chair leg 18 are equipped with wheels 24, and each wheel 24 is equipped with a lock to facilitate the overall movement and positioning of the training chair.

[0023] When the user pulls the front end of the chair seat 2 upwards, the chair seat 2 causes the flip seat 4, which is fixed to it, to rotate around the flip rod 19. The protrusion on the outer wall of the flip rod 19 moves within the sliding groove 13 of the connecting plate 7, causing the chair seat 2 to flip to the vertical position.
