A theater chair movable seat device is characterized in that: comprises an underframe 1, a positioning plate 4, a cushion component 7, a leg rest component 6, a backrest component 8 and a push rod motor 2.
The underframe 1 comprises a left side plate 11, a right side plate 11 and a front positioning pipe and a rear positioning pipe which are fixed between the two side plates 11. Supporting legs 13 are arranged at two ends of each positioning pipe respectively, the upper ends of the supporting legs 13 are fixed on the supporting pipes in a bolt or welding mode, connecting holes are formed in the lower ends of the supporting legs 13, and the supporting legs 13 can be fixed on the ground through the connecting holes and the bolts. When the positioning pipes with different lengths are selected, the distance between the two side plates 11 can be adjusted, namely the width of the theater chair can be adjusted.
As shown in fig. 2, the positioning plate 4 has a notch rearward rear mounting groove 42 at a rear position, and the positioning plate 4 has a notch downward front mounting groove 41 at a front position, while the front mounting groove 41 and the rear mounting groove 42 are perpendicular to each other. The base frame 1 has a rear mounting pin 111 for the rear mounting groove 42 and a front mounting pin 112 for the front mounting groove 41. The seat cushion assembly 7 is mounted on the positioning plate 4 and can swing back and forth relative to the positioning plate 4. When the seat cushion assembly 7 swings forwards, the height of the front side of the seat cushion assembly 7 is gradually higher than the height of the rear side of the seat cushion assembly 7, so that the comfort of lying and sitting is improved; leg rest subassembly 6 sets up in the front side of cushion subassembly 7, back subassembly 8 sets up in the rear side of cushion subassembly 7. The back assembly 8 is a back plate fixed to the rear end of the cushion assembly 7 by bolts.
The rear end of the push rod motor 2, i.e. the motor end, is connected to the positioning tube 14 located at the rear side through a U-shaped hinged base, which is the rear motor tube in this embodiment, so that the push rod motor 2 is connected to the chassis 1. The front end of the push rod motor 2 is connected with a front motor pipe 5 and is connected to a connecting rod 63 in the leg rest assembly 6 through the front motor pipe 5 so as to drive the leg rest assembly to expand or furl and the cushion assembly 7 to swing back and forth.

The upper end of the rear connecting rod 73 is hinged on the backrest plate, so that the height of the rear end of the cushion component 7 can be reduced, and the comfort of lying and sitting is improved.
Further, when the seat cushion 71 moves forward, the upper end position of the rear link 73 is gradually lowered, and the upper end position of the front link 72 is gradually raised. Specifically, the straight lines formed by the hinge holes at both ends of the rear link 73 form an angle a with the horizontal line in the clockwise direction, and the straight lines formed by the hinge holes at both ends of the front link 72 form an angle B with the horizontal line in the counterclockwise direction. When the seat device is in a fully folded state, namely a sitting position, the angle of the included angle A is smaller than or equal to 90 degrees, and the angle of the included angle B is smaller than 90 degrees. When the seat cushion 71 moves forward step by step, the included angle a decreases step by step and the included angle B increases step by step. Until the seat unit is completely opened to the leisure posture, the included angle A reaches the minimum angle, the included angle B reaches the maximum angle, and the included angle B is not more than 90 degrees. With this structure, in the process of unfolding the seat device, the height of the front end of the seat cushion 71 gradually rises, and the height of the rear side gradually falls, so that the height difference between the two ends is increased, and the comfort of lying and sitting is improved.
