Technical Field
[0001] The present application relates to the technical field of aviation seats, and in particular to an aviation seat back dining table without a tray arm structure. Background Art
[0002] Airline seats refer to the seats used on airplanes. A dining table is usually set behind the airline seat backs for passengers to have meals. In the existing technology, the dining table on the backs of airline seats usually adopts a tray arm structure. When the plane encounters turbulence, the rear passengers are prone to collide with the front seats. The connection structure of the tray arm may become a hard point in the event of a collision, and the passenger's head is prone to collide with it, causing injury to the passenger. There is a safety hazard, so it needs to be improved. Utility Model Content

The connecting bolt passes through the guide ring and the dining table tray connecting arm in sequence and is inserted into the dining table cross tube. A connecting piece is provided in the dining table cross tube, and the connecting bolt is connected to the connecting piece.
[0010] By adopting the above technical solution, guide rings and connecting bolts are used to connect with the connecting parts. On the one hand, the detachable connection of the dining table tray connecting arm can be realized, which is convenient for quick disassembly or replacement of the dining table tray connecting arm and the dining table cross tube. At the same time, the rotation of the dining table tray connecting arm can also be limited, reducing the risk of the dining table tray connecting arm falling off during rotation.
[0011] Optionally, the connecting piece is a star nut.
[0012] By adopting the above technical solution, the star nut has high stability, anti-slip and anti-vibration capabilities, which can effectively improve the stability of the connecting bolts, thereby making the pallet assembly more stable during use.
[0013] Optionally, a fixing structure for connecting the dining table cross tube to the seat back cover is provided on the dining table cross tube.
[0014] By adopting the above technical solution, setting up a fixed structure can realize a detachable connection between the dining table cross tube and the seat back cover, thereby facilitating the disassembly, maintenance or replacement of the dining table cross tube and other components, thereby improving the assembly convenience and practicality.
[0015] Optionally, the fixed structures are provided in several groups, and the several fixed structures are distributed along the length direction of the horizontal tube of the dining table.
[0016] By adopting the above technical solution and arranging the fixing structure into several groups, the stability of fixing the horizontal tube of the dining table can be fully improved, thereby ensuring the stability of the tray assembly during use.
[0017] Optionally, a tray latch for fixing the tray assembly is provided on the outside of the seat back cover.
[0018] By adopting the above technical solution, a tray latch is provided to fix the tray assembly when the tray assembly is not in use, so as to prevent the tray assembly from sliding or turning over by itself, thereby effectively improving the stability of the tray assembly.
[0019] Optionally, an outer shape transition area is provided on the outside of the seat back cover, and the outer shape transition area is located below the tray assembly.
[0020] By adopting the above technical solution, the opening of the outer shape transition area can achieve a smooth transition with the tray assembly, making the tray assembly smoother when in use.
[0021] In summary, this application includes at least one of the following beneficial technical effects:
[0022] 1. The tray assembly is slidably connected to the table tray connecting arm. When not in use, the table tray connecting arm is hidden in the tray slide, thus eliminating the safety hazard of the seat's structural hard points and the risk of passenger head impact, thereby improving the overall safety of the seat;
[0023] 2. Since the seat table tray arm structure is no longer needed, the overall weight of the seat is reduced, fuel economy is improved, and costs are saved;
[0024] 3. The guide ring and connecting bolts are used to connect with the connecting parts. On the one hand, it can realize the detachable connection of the dining table tray connecting arm, which is convenient for quick disassembly or replacement of the dining table tray connecting arm and the dining table cross tube. At the same time, it can also limit the rotation of the dining table tray connecting arm, reducing the risk of the dining table tray connecting arm falling off during rotation.
