The table board 11 can be used to place items. When not in use, the table board 11 can be screwed into the cover 2, and the armrest cover 10 can be rotated to cover the table board 11 and keep the appearance neat.

[0038] A sliding assembly 4 is installed on the swivel seat 7, and the seat body 3 is mounted on the sliding assembly 4. The sliding assembly 4 consists of a drive assembly 43, two slide rails 41, and a sliding plate 42. The two slide rails 41 are fixedly installed on the top wall of the swivel seat 7, and the two sliding plates 42 are slidably installed on the two slide rails 41. The drive assembly 43 is mounted on the two sliding plates 42. The drive assembly 43 consists of a servo motor, a gear set, and a lead screw. The lead screw is fixedly installed inside the slide rail 41, the gear set is mounted on the sliding plate 42 and connected to the lead screw, and the servo motor is connected to the gear set and drives the sliding plate 42 to reciprocate on the slide rail 41. In this application, two sliding assemblies 4 are installed, and the two sliding assemblies 4 are stacked vertically to increase the sliding distance of the seat body 3.

[0039] The seat body 3 includes a backrest 31, a seat cushion 32, a leg rest 33, and an adjustable frame 34. The adjustable frame 34 is mounted on a sliding plate 42, and the backrest 31, seat cushion 32, and leg rest 33 are mounted on an adjusting assembly. The adjustable frame 34 includes a seat frame 341, a backrest frame 342, a bracket 343, a first adjusting member 344, a second adjusting member 345, and a third adjusting member 346. The seat cushion 32 is fixedly mounted on the seat frame 341, the backrest 31 is fixedly mounted on the backrest frame 342, and the leg rest 33 is fixedly mounted on the bracket 343.

[0040] The seat frame 341 is rotatably mounted on the slide plate 42, and the first adjusting member 344 is mounted on the bottom of the seat frame 341. In this application, the first adjusting member 344 can be a motor linkage structure, and the first adjusting member 344 can drive the seat frame 341 to rotate and adjust on the slide plate 42.

[0041] The back frame 342 is rotatably mounted on one side of the seat frame 341, and the second adjusting member 345 is mounted on the seat frame 341. In this application, the second adjusting member 345 can be used as an angle adjuster, and the second adjusting member 345 can drive the back frame 342 to rotate and adjust on the seat frame 341.

[0042] The third adjusting member 346 is installed at the bottom of the seat frame 341 and on the side away from the back frame 342. The bracket 343 is installed on the adjusting end of the third adjusting member 346. In this application, the third adjusting member 346 can be a multi-link structure of a motor, and the third adjusting member 346 can drive the bracket 343 to rotate and adjust on the seat frame 341.

[0043] The sliding component 4 can drive the seat body 3 to move horizontally within the cover 2, allowing the backrest 31 to be adjusted at any angle without limitation. By adjusting the unified drive of the frame 34, the backrest 31, seat cushion 32, and leg rest 33 work together: the backrest 31 can recline at a large angle or lie flat according to the sitting posture requirements, the seat cushion 32 tilts accordingly to provide a uniform body pressure distribution, and the leg rest 33 automatically unfolds to provide effective support for the user's legs, thereby greatly improving the user's comfort and experience during the ride.

[0044] The seat body has three postures: riding posture, zero-gravity posture, and lying flat posture.

[0045] Reference Figure 1 When the seat is in a sitting position: the backrest 31 is adjusted to -5°, the leg rest 33 is adjusted to 0°, the seat cushion 32 is tilted at 4°, the first set of sliding components 4 is displaced at 0mm, and the second set of sliding components 4 is displaced at 0mm.

[0046] Reference Figure 6When the seat is in a zero-gravity posture: the backrest 31 is adjustable at an angle of 20°, the leg rest 33 is adjustable at an angle of 55°, the seat cushion 32 is tilted at an angle of 12°, the first set of sliding components 4 is displaced by 195mm, and the second set of sliding components 4 is displaced by 195mm.
