[0066] Refer to Figure 8 , as a preferred embodiment, in this embodiment, the top frame 103 includes at least one front beam 1031, at least one rear beam 1032, and side beams 1033 connecting the front beam 1031 and the rear beam 1032. Among them, the side beams 1033 and the rear beam 1032 are rectangular structural beams. Preferably, square structural beams are used.

[0067] Refer to Figure 8 , as a preferred embodiment, in this embodiment, the front beam 1031 is a sheet metal part; with this setting, a front beam 1031 with a larger load-bearing area can be manufactured as needed.

[0068] Refer to Figure 7 , as a preferred embodiment, in this embodiment, the connecting support member 102 includes a horizontal portion 1021 and support arms 1022 connected to both sides of the horizontal portion 1021. The two support arms 1022 are connected to the horizontal portion 1021 so that the connecting support member 102 is in an outwardly extended U shape.

[0069] Refer to Figure 7 , as a preferred embodiment, in this embodiment, the support arm 1022 is fixed to the side beam 1033.

[0070] Refer to Figure 5 , as a preferred embodiment, in this embodiment, a support connection plate 10221 is provided on the support arm 1022. The support connection plate 10221 is attached to the surface of the side beam 1033, and then the support connection plate 10221 is fixed to the side beam 1033 by means of threaded connectors or welding.

[0071] Refer to Figure 5 、 Figure 6 , as a preferred embodiment, in this embodiment, the support arm 1022 is parallel to the axial direction of the rotating shaft 1011, and the surface of the support connection plate 10221 forms an inclination angle a with the support arm 1022, so that the top frame 103 forms an angle b equal to a with the axial line of the rotating shaft 1011, where 0° < b < 90°.

[0072] Furthermore, 40° < b < 80°.

[0073] Refer to Figure 5 , as a preferred embodiment, in this embodiment, b is 75°.

[0074] The purpose of making the top frame 103 form an inclination angle b with the axial line of the rotating shaft 1011 is that when a person sits on a seat cushion (not shown in the figure) above the top frame 103, the center of gravity of the person moves in the direction of the backrest assembly 3, so as to achieve the purpose of comfort, and it is beneficial to prevent the person from falling off the seat cushion and getting injured when sitting or lying normally;

[0075] The purpose of setting the inclination angle a is that the rotating shaft 1011 of the bottom plate support frame can be arranged in the direction of the backrest assembly 3, so that the support arm 1022 can avoid the footrest assembly 2, providing sufficient storage space for the footrest assembly 2 to be stored below the top frame 103, reducing the interference between the footrest assembly 2 and the connecting support 102. When the storage space is sufficient, the size of the footrest assembly 2 can also be increased, so that it has a larger support area or a larger extension length.
