[0044] The present invention relates to a structural design of a cockpit seat of an electric aircraft. Figure 4a The metal main structure of the cockpit seat is shown in the figure. The backrest includes a metal U-shaped backrest bracket 110, a plastic seat back plate 220 and a seat back 320. The U-shaped backrest bracket 110 is used to fix Figure 2 The plastic seat back panel 220, the seat back 320 is arranged on the plastic seat back panel 220, and a headrest is arranged above the U-shaped backrest bracket 110. The U-shaped backrest bracket 110 is composed of three parts, namely 110a, 110b and 110c, and the three-section design can facilitate the later metal processing. In view of the riding needs of different passengers, the headrest is designed as a fine-tunable modular sliding headrest, and can meet the riding comfort of passengers with different sitting heights. The modular headrest has two different forms, which can be replaced according to the different usage needs of the driver's seat and the passenger seat.

[0045] The first form is that the passenger seat headrest is designed to have a certain bending angle on one side, which can protect the passenger's privacy on the one hand and facilitate the passenger to enjoy the scenery outside the window on the other hand. The headrest includes a fixed back plate 210 and a soft support component 310, and the soft support component 310 is fixed in the fixed back plate 210. Figure 6a The fixed back plate 210 of the headrest shown has a certain bending angle.

Preferably, a hidden display screen can also be installed inside the fixed back plate 210 to simply display the information of the reserved seat passengers, so that passengers can find their seats when boarding.

[0046] The driver's seat headrest does not have a bending angle. Figure 6a Center folding headrest replaced with Figure 6b The medium flat headrest provides a wider field of vision for the occupant in the driving seat.

[0047] Figure 6c The figure shows the connection between the fixed back plate 210 and the seat back plate 220. The fixed back plate 210 can be fixed to the seat back plate 220 by the headrest fixing ring 211, and the position of the headrest can be adjusted by adjusting the position of the ring. The modular seat back plate is mainly to meet the different usage needs of rear passengers. An entertainment screen or a small table and a cup holder can be added behind the seat back plate for the convenience of passengers. Figure 7a A non-functional seat back panel 220 is shown having no other functions but can reduce the overall weight of the seat. Figure 7b Another multifunctional seat back panel 220 is shown in the figure, behind which is a multimedia display screen 221 and a folding small table 222 to meet the different usage needs of rear passengers.

[0048] Due to the limited cabin space in the electric vertical take-off and landing aircraft eVTOL, the seat armrests are not necessary facilities for every seating position. Therefore, the armrests are configured to be detachable. The armrests 410 and 420 are arranged above the seat surface on both sides of the backrest and are fixed by fixed shafts 413 and 423. Specifically, the two ends of the U-shaped opening of the U-shaped backrest bracket 110, the upper ends of the two supporting feet and the intersection of the armrests 410 and 420 are fixed by fixed shafts 413 and 423. In addition, the seat armrests can also be rotated by fixed shafts 413 and 423, thereby reducing the time for passengers to board and disembark. The seat armrest 410 or 420 is composed of three parts, namely a metal component 410a or 420a, a soft material component 410b or 420b, and a plastic component 410c or 420c. The three components can be fixed by bolts and combined into a seat armrest. In addition, when it is not needed, by removing the Figure 5The fixed shafts 413, 423 in the middle can remove the seat armrests 410 and / or 420. By removing some of the seat armrests, not only the overall weight of the seat can be reduced, but also the space utilization of the overall cabin can be improved.

[0049] Preferably, the support legs of the present invention are Y-shaped metal legs. Figure 4a The two Y-shaped metal legs 131 and 132 are fixedly connected to the U-shaped backrest bracket 110 and the seat arms 121 and 122 to support most of the weight of the seat. The forked end of the Y-shaped metal leg is arranged below the seat surface as the bottom end, and the vertical end is arranged above the seat surface as the top end, and the top end is connected to the open end of the U-shaped backrest bracket 110.
