The armrest cover plate covering component is installed outside the outer armrest cover. An armrest is installed above the armrest cover plate covering component. An integrated armrest mounting plate is installed between the armrest cover plate covering component and the outer armrest cover. The integrated armrest mounting plate and the outer armrest cover are fixedly installed. Linear slide rails are arranged on both sides of the integrated armrest mounting plate. Sliders are slidably installed on the linear slide rails, and the sliders are installed on the armrest cover plate covering component. The large gear, the small gear, the wire rope wheel, and the motor are installed on the integrated armrest mounting plate. The large gear and the small gear are meshed and installed. The small gear is driven by the motor. One wire rope wheel is installed on each side below the integrated armrest mounting plate, and one wire rope wheel is installed on each side above the integrated armrest mounting plate. The four wire rope wheels are distributed in a rectangle. Two tensioning wheels are installed below the inner sides of the two upper wire rope wheels. An auxiliary wheel is arranged between the two tensioning wheels. A wire rope crimping seat is arranged above the two lower wire rope wheels, and the wire rope crimping seat is fixedly installed inside the outer armrest cover.

[0004] A wire rope wheel is installed inside the large gear. After the wire rope winds out from below the wire rope wheel, it winds out from below the left lower wire rope wheel, then enters above the left upper wire rope wheel, above the right tensioning wheel, below the right lower wire rope wheel, above the right upper wire rope wheel, below the auxiliary wheel, and above the left upper tensioning wheel in sequence, and finally enters the wire rope wheel to form a closed loop. The wire rope crimping seat is respectively crimped on the wire ropes outside the two lower wire rope wheels.

[0005] The lifting principle of the lifting armrest for business area seats is as follows: the motor drives the small gear to rotate, the small gear drives the large gear to rotate, the large gear drives the movement of the wire rope wheel, the wire rope wheel further drives the rotation of the wire rope, the rotation of the wire rope drives the synchronous up and down movement of the two wire rope crimping seats, and the wire rope crimping seats drive the lifting of the armrest cover plate covering component, thereby driving the lifting of the armrest.

[0006] Further, magnetic switches are respectively installed on the upper, middle and lower parts of the armrest integrated mounting plate.

[0007] Further, a controller is installed on the armrest integrated mounting plate, and the lifting of the armrest can be controlled by a button in the private room, improving the comfort of using the seat.

[0008] The lifting function of the lifting armrest of the business area seat is controlled by a controller. When the sitting and lying postures of the seat are controlled by a button in the private room, the armrest is linked with the seat to realize the lifting of the armrest; when the seat is in a lying flat state, the armrest drops to the lowest point; when the seat is in a sitting position, the armrest rises to the middle position; when the small table board of the seat is in an open state, the armrest will rise to the highest point.

[0009] Beneficial effects:

[0010] 1. The structure of the present invention is simple and has low noise. The running direction of the steel wire ropes ensures that the two steel wire rope crimping seats move up and down together. The steel wire rope crimping seats drive the armrest cover plate to wrap and form a lift, and then drive the armrest to lift. The armrest adapts to the seat state and lifts.

[0011] 2. The reasonable layout of the steel wire rope wheels, rope wheels, tensioning wheels and auxiliary wheels in the present invention avoids the entanglement of the steel wire ropes and ensures the smooth traction of the steel wire ropes. Description of the drawings
