[0002] Many people need to sit for long periods of time at work, and the choice of office chair plays a decisive role in the user's comfort during long periods of sitting. Common office chairs include a seat, a backrest and a foot pad, and in order to facilitate the installation and fixation of the seat, backrest and foot pad, a bracket is usually provided, and the seat, backrest and foot pad are all installed on the bracket. However, the bracket of a conventional office chair cannot be adjusted after it is set, and the position of the backrest and foot pad set thereon is difficult to adjust compared to the position of the seat.
[0003] CN219920643U discloses a dual electric leisure office chair bracket, which includes a foot pad bracket for mounting a foot pad and a backrest bracket for mounting a backrest, and is also provided with a first electric push rod and a second electric push rod, which can adjust the positions of the foot pad bracket and the backrest bracket respectively. However, the dual electric leisure office chair bracket needs to be provided with a first electric push rod and a second electric push rod at the same time to adjust the backrest bracket and the foot pad bracket respectively. Although the adjustable range is large, the number of electric push rods required is large, and the cost is high.
[0004] On the other hand, the above-mentioned dual electric leisure office chair bracket also includes an armrest frame, and the armrest frame is correspondingly provided with protrusions. However, when the armrest frame of the bracket is actually used, in addition to the armrests, a seat needs to be provided together. Since it is an integrated design, the actual position of the armrest can only be close to the seat, and the flexibility of the armrest setting is poor. At the same time, the armrest frame only relies on the protrusions to increase the contact with the armrest, and the connection reliability between them is still not strong. Utility Model Content
