It should be understood that the specific examples described herein are only used to explain the utility model and not to limit the utility model.

[0028] In order to solve the technical problem of how to maintain the stable upwarping angle of the seat plate 200, the utility model provides an aviation seat, which can keep the upwarping angle of the seat plate 200 within a proper range, thereby ensuring the passenger's riding experience.

[0029] It should be noted that the aviation seat of the utility model is used for but not limited to civil aircraft and the like. For the convenience of description, in the utility model, the aviation seat is only taken as an example applied to a civil aircraft, and the principle of the aviation seat applied to other types of equipment is substantially the same as that applied to the civil aircraft, which will not be described here.

[0030] Please refer to Figure 1 , Figure 1 Fig. 1 is a structural schematic view of the aviation seat in an embodiment of the utility model. The aviation seat comprises a support frame 100, a seat plate 200, a chair back 300 and a transmission assembly 400. The seat plate 200 is slidingly arranged on the support frame 100. The chair back 300 is rotatably installed on the support frame 100. The transmission assembly 400 comprises a first connecting piece 410 and a second connecting piece 420. One end of the first connecting piece 410 is rotatably connected to the chair back 300. The second connecting piece 420 is hingedly connected to the other end of the first connecting piece 410 and the seat plate 200 respectively.

[0031] In this embodiment, the seat plate 200 is slidingly arranged on the support frame 100, and the chair back 300 is rotatably installed on the support frame 100. The chair back 300 and the seat plate 200 are drivingly connected through the first connecting piece 410 and the second connecting piece 420, so that the overturned chair back 300 can drive the seat plate 200 to slide, and the relative positions of the seat plate 200 and the chair back 300 can adapt to the sitting posture of the passenger. Since the seat plate 200 can only slide relative to the support frame 100, the seat plate 200 can be prevented from overturning and upwarping, so that the upwarping angle of the seat plate 200 is within a proper range, thereby ensuring the passenger's riding experience.

[0032] As long as the embodiments in which the seat plate 200 can slide relative to the support frame 100 are feasible, in some of the embodiments, the support frame 100 has a sliding rail 110, and the seat plate 200 slides along the sliding rail 110.

[0033] On the basis of the above-mentioned embodiments, in some of the embodiments, the sliding rail 110 is provided with a first sliding groove 111, and the seat plate 200 is provided with a first guide wheel 210, and the first guide wheel 210 slides along the first sliding groove 111 to make the seat plate 200 slide along the first sliding groove 111. In the process of sliding of the seat plate 200, the first guide wheel 210 rolls along the first sliding groove 111, and the cooperation between the first guide wheel 210 and the first sliding groove 111 can limit the sliding track of the seat plate 200 on one hand, and can reduce the sliding resistance of the seat plate 200 relative to the support frame 100 on the other hand.

[0034] In some of the embodiments, the first sliding groove 111 is arc-shaped. Since the shape of the first sliding groove 111 determines the sliding track of the seat plate 200, the arc-shaped first sliding groove 111 makes the sliding track of the seat plate 200 also arc-shaped, so that the moving track of the seat plate 200 can be closer to the track of stretching the body of the passenger, thereby improving the comfort of the passenger.

[0035] In some of the embodiments, the transmission assembly 400 further comprises a resilient member 430, one end of the resilient member 430 is hingedly connected to the seat plate 200, the other end of the resilient member 430 is hingedly connected to the support frame 100, and the resilient member 430 has an elastic force to drive the seat plate 200 to be close to the chair back 300. When the aviation seat is not used, the resilient member 430 drives the seat plate 200 to be close to the chair back 300, and since the seat plate 200 and the chair back 300 are hingedly connected, the chair back 300 is further turned to the direction close to the seat plate 200, thereby being reduced. When the passenger sits on the aviation seat, the chair back 300 is turned backward, and the seat plate 200 moves in the direction away from the chair back 300, so that the relative positions of the chair back 300 and the seat plate 200 adapt to the needs of the passenger.

[0036] In some of the embodiments, the bottom surface of the seat plate 200 is provided with a receiving groove 220, and the resilient member 430 is partially hidden in the receiving groove 220. Since the resilient member 430 is partially hidden in the receiving groove 220, the space occupied by the seat plate 200 and the resilient member 430 overlaps each other, thereby saving the installation space of the resilient member 430.

[0037] On the basis of the above-mentioned embodiments, in some of the embodiments, the resilient member 430 comprises a pneumatic spring 431, one end of a cylinder body of the pneumatic spring 431 is rotatably embedded in the receiving groove 220, and a piston rod of the pneumatic spring 431 is hingedly connected to the support frame 100. When the seat plate 200 and the chair back 300 are away from each other, the pneumatic spring 431 is contracted to store elastic potential energy, and when the seat plate 200 and the chair back 300 are close to each other, the pneumatic spring 431 is elongated to release the elastic potential energy.

[0038] As long as the embodiments in which the piston rod of the pneumatic spring 431 can rotate relative to the support frame 100 are feasible, in some of the embodiments, the elastic member 430 further comprises a rotating shaft 432, one end of the rotating shaft 432 is rotatably installed on the support frame 100, and the other end of the rotating shaft 432 is connected to the piston rod of the pneumatic spring 431.

[0039] In some of the embodiments, the transmission assembly 400 further comprises a limiting pin 440, one end of the limiting pin 440 is connected to the rotating shaft 432, and the bottom end of the seat plate 200 is further provided with a limiting groove 230, and the limiting groove 230 is sleeved with the other end of the limiting pin 440. Since the limiting groove 230 is sleeved with the other end of the limiting pin 440, the limiting pin 440 can slide relative to the limiting groove 230, and the limiting pin 440 and the limiting groove 230 can play a limiting role in the process of sliding the seat plate 200, thereby further preventing the seat plate 200 from being upturned.

[0040] In some of the embodiments, the hinge point of the first connecting member 410 is coaxially arranged with the rotating shaft of the chair back 300, and the first connecting member 410 is further provided with a circular arc groove 411 surrounding the hinge point, and the chair back 300 is provided with a second guide wheel 310, and the second guide wheel 310 slides along the circular arc groove 411.

[0041] In order to better understand the present application, the technical solutions of the present application are described in detail as follows:

[0042] The first guide wheel 210 rolls along the first sliding groove 111, thereby causing the seat plate 200 to slide relative to the support frame 100, and the chair back 300 is rotatably installed on the support frame 100, and when the aviation seat is not in use, the elastic member 430 drives the seat plate 200 to move close to the chair back 300, and since the seat plate 200 and the chair back 300 are connected to each other, the chair back 300 is turned in the direction of moving close to the seat plate 200, thereby being reduced. After the passenger sits on the aviation seat, the chair back 300 is turned backward, and the seat plate 200 moves away from the chair back 300, so that the relative position of the chair back 300 and the seat plate 200 adapts to the needs of the passenger. Since the seat plate 200 can only slide relative to the support frame 100, the seat plate 200 can be prevented from being upturned, so that the upturning angle of the seat plate 200 is within a proper range, thereby ensuring the riding experience of the passenger.

[0043] The specific embodiments of the present application described above do not constitute a limitation on the protection scope of the present application. Any other corresponding changes and modifications made according to the technical concept of the present application shall be included in the protection scope of the claims of the present application.
