[0049] Specifically, each of the first connecting seats 5 is arranged around the lower end of the backrest frame 1 and is fixedly connected to the lower end of the backrest frame 1. The first connecting seat 5 is provided with an opening facing the corresponding second bracket 32. The rear end of the second bracket 32 ​​is disposed inside the first connecting seat 5 and is rotatably connected to the first connecting seat 5.

[0050] like Figure 1 As shown, each of the first connecting seats 5 is provided with a guide portion 10, and each guide portion 10 is inclined downward from front to back. Each of the second brackets 32 is rotatably and slidably connected to its corresponding guide portion 10. The guide portion 10 is specifically a guide hole.

[0051] like Figure 2 and Figure 4As shown, the first bracket 31 has a buffer cavity 4, and the front bottom wall of the buffer cavity 4 has a first abutment portion. The front end of the second bracket 32 ​​has a second abutment portion. The elastic reset member 33 is disposed in the buffer cavity 4 and between the first abutment portion 34 and the second abutment portion 34. The elastic reset member 33 includes a spring. The buffer cavity 4 makes the installation of the elastic reset member 33 more stable and more stable when the second bracket 32 ​​compresses the elastic reset member 33.

The backrest frame 1 is arranged in the second connecting seat 6 and is rotatably connected to the second connecting seat 6.

[0060] Working principle explanation:

[0061] In this invention, the seat achieves automatic reset of the backrest assembly through the elastic reset member 33;

[0062] When an external force drives the backrest assembly to rotate backward relative to the seating support, each of the first supports 31 moves forward relative to its corresponding second support 32, pressing the elastic reset member 33. Each of the elastic reset members 33 stores energy and provides an elastic reset force to the backrest assembly to rotate forward and reset. This elastic reset force pushes the first support 31 backward, causing the first support 31 to return to its initial position.

[0063] The first support rod 7, the second support rod 8, and the third support rod 9 ensure that the backrest frame 1 will not completely collapse due to excessive external force.
