Description

Technical Field

[0001] The utility model relates to the technical field of aircraft seats, in particular to an aircraft seat backrest connecting plate. Background Art

[0002] Aircraft seats are comfortable companions for passengers during air travel. They are cleverly designed and installed in the aircraft cabin to adapt to the needs of different flight phases. Although aircraft seats have similarities with car and train seats in basic structure, they are tailor-made for air travel in details and functions.

[0003] Aircraft seats consist of a seat cushion and a backrest, which are tightly connected by a sturdy connecting plate. The connecting plate is usually designed on the side of the seat, which not only keeps the seat's appearance neat but also ensures the stability of the structure. This design allows passengers to easily adjust the angle of the backrest according to their personal preferences for optimal support and comfort.

[0004] Although the design of aircraft seats is constantly improving, there are still some challenges in the current installation process. Existing aircraft seats usually use screws and screws to fix the seat cushion and backrest to the connecting plate. Although this installation method ensures the stability of the seat, it also brings certain complexities. In actual operation, this installation process may appear to be more cumbersome and requires a certain amount of time and professional skills to complete. In particular, the backrest part is easily stained and dusty during frequent use. In order to maintain the comfortable riding experience of passengers, airlines need to clean and disinfect the backrest regularly. However, since the disassembly process of the backrest involves screws and connecting plates, this requires the use of professional tools, which increases the difficulty and time cost of maintenance. Therefore, an aircraft seat backrest connecting plate is proposed to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See also Figure 1-6 In this embodiment, an aircraft seat back connection plate includes a connection plate body 1, a first mounting hole 2 is provided inside the connection plate body 1, a second mounting hole 3 is provided inside the connection plate body 1, a movable shaft mounting hole 4 is provided inside the connection plate body 1, an arc-shaped adjustment groove 5 is provided inside the connection plate body 1, and a convenient disassembly mechanism 6 is provided outside the connection plate body 1;

[0028] The disassembly mechanism 6 includes a plug-in sleeve 601, a movable shaft body 602, an adjusting sleeve 603, a backrest fixing plate 604, a limiting rod 605, a limiting block 606, an arc ring 607, a threaded sleeve 608, a threaded shaft 609, a limiting ring 610, a fixing sleeve 611, a first tension spring 612, a cross plug-in rod 613 and a cross plug-in seat 614. The plug-in sleeve 601 is fixedly installed inside the movable shaft mounting hole 4, the movable shaft body 602 is plugged inside the plug-in sleeve 601, the outer sleeve of the movable shaft body 602 is sleeved with the adjusting sleeve 603, the top of the adjusting sleeve 603 is fixedly installed with the backrest fixing plate 604, and the backrest fixing plate 614 is fixedly installed on the top of the adjusting sleeve 603. 04 is fixedly installed with a limit rod 605 on the front side, the limit rod 605 is threadedly connected to a limit block 606 on the front side, an arc ring 607 is fixedly installed on the bottom of the adjusting sleeve 603, a threaded sleeve 608 is fixedly installed on the back side of the connecting plate body 1, the threaded sleeve 608 is internally rotatably connected to a threaded shaft 609, the threaded shaft 609 is externally threadedly connected to a limit ring 610, a fixed sleeve 611 is fixedly installed on the front side of the connecting plate body 1, the inner front wall of the fixed sleeve 611 is rotatably connected to a first tension spring 612, the interior of the first tension spring 612 is sleeved with a cross plug rod 613, and the outside of the threaded shaft 609 is fixedly installed with a cross plug seat 614.

[0029] Specifically, after the cross plug rod 613 is plugged into the cross plug seat 614, the entire disassembly mechanism 6 is activated. At this time, it is possible to rotate the threaded shaft 609 and control the movement of the limit ring 610. When the threaded shaft 609 is rotated, it drives the limit ring 610 to move along the axial direction of the adjustment sleeve 603. Specifically:

[0030] This movement is divided into two directions: leftward and rightward. When the limiting ring 610 moves to the left, it pushes the adjusting sleeve 603 to move along the axis direction of the movable shaft body 602, thereby increasing the effective length of the movable shaft body 602. At this time, the movable shaft body 602 is plugged into the plug-in sleeve 601 to achieve stable fixation of the backrest, ensuring that passengers enjoy stable support during the flight.

[0031] On the contrary, when the limit ring 610 moves to the right, the adjustment sleeve 603 will move in the opposite direction, and the effective length of the movable shaft body 602 will be reduced, which causes the connection between the movable shaft body 602 and the plug-in sleeve 601 to be released, so that the backrest can be pulled upward and removed, thereby simplifying the disassembly process and greatly improving the efficiency and convenience of maintenance.

[0032] Specifically, the movable shaft body 602 includes a connecting sleeve 6021, two movable plug rods 6022, a plug-in shaft 6023 and a second tension spring 6024. The second tension spring 6024 will continuously pull the two movable plug rods 6022. This makes it possible for the two movable plug rods 6022 to move rapidly relative to each other when the limit ring 610 moves to the right due to the loss of the locking and limiting effect of the limit ring 610 on the arc ring 607. Therefore, the length of the entire movable shaft body 602 is reduced and it is disengaged from the plug-in sleeve 601.

[0033] Specifically, the first mounting hole 2 and the second mounting hole 3 match the corresponding parts of the seat cushion to ensure a firm connection between the seat cushion and the connecting plate, and a backrest fixing plate 604 is fixedly installed on the top of the adjustment sleeve 603 to facilitate the close combination of the backrest and the connecting plate. A limit rod 605 is fixedly installed on the front of the backrest fixing plate 604 and passes through the arc-shaped adjustment groove 5, thereby providing convenience for adjusting the angle of the backrest. With the guidance of the arc-shaped adjustment groove 5, the passenger can easily adjust the angle of the backrest according to his or her comfort and enjoy a more personalized riding experience. At the same time, the arc-shaped adjustment groove 5 also limits the angle of the backrest to ensure safety during the adjustment process and the integrity of the seat structure.

[0034] In summary, the aircraft seat back connection plate, through the easy-to-disassemble mechanism 6, only needs to easily rotate and remove the limit block 606, and then drive the threaded shaft 609 by rotating the cross plug rod 613, so as to cause the arc ring 607 to separate from the limit ring 610, and then the plug sleeve 601 is disengaged from the movable shaft body 602, and the backrest can be directly pulled upward, so as to be easily separated from the seat cushion. The whole process does not require the removal of screws and bolts, which simplifies the disassembly steps and greatly improves the maintenance efficiency. It solves the problem that the existing aircraft seats usually use bolts and bolts to fix the seat cushion and the backrest on the connection plate. This installation method is relatively cumbersome and increases the difficulty and time cost of seat back maintenance.
