Description

Technical Field

[0001] This utility model relates to the field of seat armrest technology, specifically to an adjustable device for civil aviation seat armrests. Background Technology

[0002] With the development of technology and the improvement of living standards, the modern aviation industry is paying more and more attention to the comfort of aircraft seats. Armrests are an indispensable part of aircraft seats, providing support for passengers' arms and playing a crucial role in the comfort of the seats.

[0003] Currently, the armrests of seats in civil aircraft, transport aircraft, and helicopters have relatively simple functions, with only two usage states: lying flat and folding back to be flush. The position of the armrests is relatively fixed, and this fixed armrest device cannot meet the seating needs of all passengers, affecting seating comfort. To address this, we propose an adjustable armrest device for civil aircraft seats. Utility Model Content

[0004] To address the shortcomings of existing armrests with fixed positions that cannot meet the seating needs of all passengers and affect seating comfort, this utility model provides an adjustable armrest device for civil aviation seats. It has the advantage of extending the top length of the armrest shell to meet the support needs of passengers' arms at different placement positions, thus solving the problems mentioned in the background art.

[0005] The technical solution of this utility model is implemented as follows: A civil aviation seat armrest adjustment device includes an adjustment seat slidably connected to the top of the armrest housing, a sponge pad installed on the top of the adjustment seat, and a strip groove opened on the top of the armrest housing, and a sliding seat slidably connected in the strip groove, thereby rotatably connecting the adjustment seat and the top of the sliding seat; an installation chamber is opened on the top of the sliding seat, and a connecting seat is rotatably connected in the installation chamber, thereby fixing the connecting seat to the bottom of the adjustment seat.

[0006] Optionally, a first guide groove is formed on the sliding seat, and a first guide rod passing through the first guide groove is tightly fixed in the strip groove.

[0007] Optionally, a rubber sleeve is coaxially connected inside the first guide groove, and the first guide rod is coaxially connected to the rubber sleeve.

[0008] Optionally, a second guide groove is symmetrically opened on the sliding seat along the first guide groove, and a second guide rod is installed through the second guide groove, with the second guide rod being fastened to the inner wall of the strip groove.

[0009] Optionally, a support rod is fastened to the bottom of the connector, and the bottom of the support rod is rotatably connected to the bottom of the mounting chamber via a bearing.

[0010] Optionally, multiple second paddles are connected circumferentially on the inner wall of the mounting cavity, and multiple first paddles are fixedly connected circumferentially on the outer wall of the support rod, with the first paddles and second paddles spaced apart.

[0011] Optionally, one end of the armrest housing has a downwardly extending arc segment.

[0012] Compared with the prior art, this utility model can push and rotate the adjustment seat according to the passenger's usage needs, thereby driving the adjustment seat and sponge pad to extend the top length of the armrest shell. At the same time, under the action of rotation adjustment, it can also meet the support of the passenger's arm at different placement positions, effectively improving the practicality of the device and improving the passenger's riding comfort.

[0020] The technical solution of this utility model will be clearly and completely described below with reference to its embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] Reference Figures 1 to 5 This utility model provides a technical solution: a civil aviation seat armrest adjustment device, including an adjustment seat 5 slidably connected to the top of the armrest housing 2, a sponge pad 4 installed on the top of the adjustment seat 5, and a strip groove 3 formed on the top of the armrest housing 2, with a sliding seat 9 slidably connected within the strip groove 3. Figure 3 , 5 As shown, in order to achieve stable sliding of the adjusting seat 5 in the strip groove 3, a first guide groove 17 is opened on the sliding seat 9, and a first guide rod 6 passing through the first guide groove 17 is tightly fastened in the strip groove 3. At the same time, in order to ensure the stable placement of the adjusting seat 5 after sliding adjustment, a rubber sleeve 11 is coaxially connected in the first guide groove 17. The first guide rod 6 is coaxially connected to the rubber sleeve 11. Under the damping action of the rubber sleeve 11, not only can the adjusting seat 5 be properly slid adjusted, but the position of the adjusted adjusting seat 5 can also be fixed.

[0022] Meanwhile, to further improve the stability of the sliding seat 9 sliding within the strip groove 3, such as... Figure 3 , 5 As shown, a second guide groove 7 is symmetrically opened on the sliding seat 9 along the first guide groove 17, and a second guide rod 8 is installed through the second guide groove 7. The second guide rod 8 is fastened to the inner wall of the strip groove 3. By pushing the adjusting seat 5, the length of the top of the handrail shell 2 can be extended to meet the usage needs of different passengers.

[0023] To further improve the practicality of the armrest shell 2, such as Figure 2 , 3 As shown in Figure 5, the top of the adjusting seat 5 is rotatably connected to the top of the sliding seat 9. An installation chamber 10 is opened on the top of the sliding seat 9. A connecting seat 12 is rotatably connected inside the installation chamber 10. A support rod 13 is fastened to the bottom of the connecting seat 12. The bottom of the support rod 13 is rotatably connected to the bottom of the installation chamber 10 through a bearing 16. The connecting seat 12 is fixedly connected to the bottom of the adjusting seat 5. The adjusting seat 5 is rotated so that the bottom of the support rod 13 can rotate stably inside the installation chamber 10, which can meet the needs of passengers' arms to be placed and supported in different directions.

[0024] like Figure 5As shown, to ensure the stable placement of the adjusting seat 5 after rotation, multiple second paddles 15 are connected circumferentially on the inner wall of the mounting chamber 10, and multiple first paddles 14 are fixedly connected circumferentially on the outer wall of the support rod 13. The first paddles 14 and the second paddles 15 are spaced apart. When the adjusting seat 5 is rotated, the first paddles 14 and the second paddles 15 move against each other and limit and lock each other, effectively limiting the placement of the adjusting seat 5.

[0025] In summary, this civil aviation seat armrest adjustment device, when in use, has a downwardly extending arc-shaped section 1 at one end of the armrest housing 2, and the arc-shaped section 1 is rotatably connected to the seat. According to the needs of use, the passenger pushes the adjustment seat 5, causing it to slide on the top of the armrest housing 2, effectively extending the length of the top of the armrest housing 2. Moreover, the adjustment seat 5 can be rotated and adjusted on the top of the armrest housing 2, thereby meeting the support needs of the passenger's arm at different placement positions, effectively improving the practicality of the device.

[0026] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
