The first motor 240 is coupled to the first main link and is adapted to drive the first main link to rotate, thereby driving the first secondary link to rotate.

Further, in this embodiment, the length of the first connector 210 is smaller than the length of the second connector 220 in the first vertical plane, and the design is such that when the movable armrest assembly 11 is in the first configuration, the end of the main body portion 110 away from the connecting portion 120 is closer to the cushion bracket 12 than the connecting portion 120 in the y direction, so that the armrest bracket 100 can be conveniently stored, and tilted toward the cushion bracket 12, so that the space is saved, and in some embodiments, the armrest bracket 100 can be directly received in the soft package of the cabin seat 10 in the first configuration (see fig. 6). Further, in the embodiment shown in fig. 2, the second connecting member 220 is curved, and the first connecting member 210 may overlap the second connecting member 220 when the movable armrest assembly 11 is in the first configuration.

Specifically, when the movable armrest assembly 11 is in the first configuration, the armrest support 100 is in the stored state, and at this time, the at least one first engagement portion 313 of the clutch assembly 310 is separated from the at least one second engagement portion 122 of the recliner 121, and the second driving assembly 300 cannot drive the armrest support 100. As the first driving assembly 200 drives the armrest support 100 to rotate upward in the first vertical plane, the at least one first clamping portion 313 of the clutch assembly 310 and the at least one second clamping portion 122 of the recliner 121 are clamped, and the second driving assembly 300 may drive the armrest support 100 to swing in the second vertical plane, thereby adjusting the angle of the armrest support 100 to extend in the y-direction. After use, it is also necessary that the second driving assembly 300 first drives the handrail support 100 to swing in the second vertical plane to extend along the z direction, and then the first driving assembly rotates the handrail support 100 downward in the first vertical plane, and the first clamping portion 313 and the angle adjuster 121 are separated until the handrail support 100 returns to the first configuration, and the handrail support 100 is received again.

Further, in this embodiment, the second motor 320 is connected to the flexible transmission shaft 330 through a second driving disc 340, the second motor 320 is adapted to drive the second driving disc 340 to rotate, a second protrusion (for an angle reason not shown) is formed on a surface of the second driving disc 340, a second groove (for an angle reason not shown) is formed on an end of the flexible transmission shaft 330, which is adapted to be connected to the second motor 320, the second groove is adapted to form-fit with the second protrusion, and the second groove and the second protrusion cannot rotate relatively. The specific matching manner can refer to the description of the first groove and the first protrusion in the foregoing, and will not be repeated here.

Further, in the preferred embodiment shown in FIGS. 1-4, the clip 311 is adapted to telescope in the x-direction. Since the clamping member 311 of the present application can rotate in the second vertical plane, there are some cases where the first and second clamping portions 313 and 122 are already close to but not aligned. When the first drive assembly 200 has rotated the armrest support 100 upward in the first vertical plane but the first and second clamping portions 313, 122 are not aligned, at which time the clamping member 311 is in contact with the recliner 121 but the at least one first and second clamping portions 313, 122 are not able to complete the clamping, the recliner 121 is adapted to compress the clamping member 311 in the x-direction and then continue to rotate the clamping member 311 in the second vertical plane until the at least one first and second clamping portions 313, 122 are aligned, the clamping member 311 is no longer compressed, pops out, and is clamped with the recliner 121. Specifically, the opposing surfaces of the clamping member 311 and the recliner 121 in the preferred embodiment are smooth.

The change in state of the movable armrest assembly 11 is described in detail below in connection with fig. 1-5:

When the first configuration of the movable armrest assembly 11 is switched to the second configuration, the angle of the armrest support 100 in the second vertical plane may not be temporarily adjustable because the second drive assembly 300 and the armrest support 100 are separated. First, the first driving assembly 200 drives the armrest support 100 to rotate upward in the first vertical plane, during which the second driving assembly 300 is connected to the armrest support 100, the armrest support 100 is first moved away from and then brought closer to the cushion support 12, and then the second driving assembly 300 drives the armrest support 100 to rotate in the second vertical plane until the armrest support 100 extends in the y-direction, thereby achieving a usable state while saving lateral space.

When the second configuration of the movable armrest assembly 11 is switched to the first configuration, the second drive assembly 300 first drives the armrest support 100 to rotate in the second vertical plane until the armrest support 100 extends in the z-direction, then the first drive assembly 200 drives the armrest support 100 to rotate downward in the first vertical plane, during which the armrest support 100 moves away from and again closer to the cushion support 12, and the second drive assembly 300 and the armrest support 100 separate, and the armrest support 100 returns to the stowed configuration.

Referring now to fig. 1-5 in combination, the present invention also provides a cabin seat 10 including a bracket structure and a movable armrest assembly 11 as in any of the previous embodiments. Wherein the support structure comprises a cushion support 12 and a cushion support 16 connected, the cushion support 12 comprising opposing first and second stringers 13, 14 and at least one cross member 15 located between the first and second stringers 13, 14, the first and second stringers 13, 14 extending in the z-direction and the cross member 15 extending in the x-direction perpendicular to the z-direction. The movable arm rest assembly 11 is mounted on the cushion bracket 12 and is adapted to rotate in a first vertical plane and in a second vertical plane. The movable armrest assembly 11 is described above for details, and will not be described in detail herein.

Fig. 6-7 are perspective views of the cabin seat of the present application in use.
