[0025] Reference Figure 1 , 2 3. The sofa chair includes a backrest 200, a seat frame 100, a driving assembly, a telescopic frame and a footrest 400. The overall structure of the seat frame 100 is a rectangular cube structure. The footrest 400 and the backrest 200 are respectively arranged at both ends of the seat frame 100. The driving assembly is arranged in the seat frame, which includes a first telescopic rod 310 and a second telescopic rod 320. The backrest 200 is hinged to the seat frame 100 near the lower end. One end of the first telescopic rod 310 is hinged to the base, and the other end is hinged to the lower end of the backrest 200. The backrest 200 is driven to rotate around the hinge with the seat frame 100 through the extension and retraction of the first telescopic rod 310. The telescopic frame is used to connect the footrest 400 and the seat frame 100. It can drive itself to extend and retract under the drive of the second telescopic rod 320, so that the footrest 400 can be stored or extended out of the seat frame 100.
[0026] Reference Figure 3 and 4 The seat frame 100 includes two side frames 110 and a cross frame 120 connected to the frame.
