Description

Technical Field

[0001] This utility model relates to the field of marine rescue auxiliary equipment technology, and in particular to a seat cover for a marine rescue helicopter and a rescue helicopter. Background Technology

[0002] For professional maritime rescue flight teams, aircraft are an indispensable rescue tool. Rescue helicopters operate year-round in the saline environment of the sea, where the temperature and humidity are high, and the seawater is rich in salt. Seawater is a natural electrolyte solution with a very high salt concentration, which creates an excellent reaction environment for electrochemical corrosion, making our helicopter cabins highly susceptible to corrosion.

[0003] In actual rescue operations, helicopters fly close to the sea surface, exposing them to severe corrosion. Especially after a rescue flight, lifeguards who dive into the water bring seawater into the cabin. When they sit on the seats, this seawater seeps into the fuel tank seats, causing corrosion and potentially leading to fuel leaks.

[0004] It should be noted that the information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model, and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0024] Please see Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the structure of a seat cover for a maritime rescue helicopter provided in one embodiment of the present invention; Figure 2 This is a structural schematic diagram from another perspective of a seat cover for a maritime rescue helicopter provided in one embodiment of the present invention.

[0025] To solve the technical problem of seawater easily seeping into the fuel tank seat and causing corrosion, or to achieve at least one or more of the aforementioned advantages, an embodiment of this utility model provides a seat cover for a maritime rescue helicopter.

[0026] As shown in the figure, the seat cover for the maritime rescue helicopter includes a seat surface 10 and a backrest 20. Both the seat surface 10 and the backrest 20 are made of leather or other waterproof materials, possessing good abrasion resistance and waterproof performance, and can repel seawater to prevent seawater leakage.

[0027] The backrest 20 and the seat 10 are sewn together. Of course, the size and specifications of the seat 10 and the backrest 20 can be customized according to the actual size of the seat of the rescue helicopter to be installed, and this case does not impose such restrictions.

[0028] Because rescuers often have a lot of seawater on them after a rescue flight, the seat cover for this maritime rescue helicopter also includes side wings 30 to prevent seawater from seeping into the helicopter's fuel tank seats and causing corrosion.

[0029] The side wings 30 are connected to the seat surface 10 and the backrest 20 respectively. In practice, the side wings 30 are also made of leather or waterproof material. The side wings 30 are sewn together with the seat surface 10 and the backrest 20. The side wings 30 can improve the waterproof performance of the seat cover for the maritime rescue helicopter, and can prevent seawater from seeping into the fuel tank seat of the rescue helicopter from the sides of the seat surface 10 and the backrest 20, causing corrosion.

[0030] Preferably, a waterproof layer may be provided on the back of the seat surface 10, the backrest 20 and the side wings 30 (on the side closest to the helicopter seat) to further improve the waterproof performance of the seat cover for the maritime rescue helicopter.

[0031] Furthermore, the side wing 30 can be filled with supporting material to provide support for the side wing 30, keep the side wing 30 upright, increase the protective area of ​​the side wing 30, and prevent seawater leakage caused by deformation and collapse of the side wing 30. Preferably, the supporting material filled inside the side wing 30 is a soft foam material, such as EVA, which can provide support while having a certain degree of softness and elasticity, providing protection and avoiding impacts.

[0032] Based on the above, the side wing 30 has an extension 40 and an extension 50.

[0033] The extension 40 is formed by extending the side wing 30 away from the backrest 20. The extension 40 is also made of leather or waterproof material. The extension 40 and the side wing 30 can be integrally molded or sewn together. The extension 40 is not filled with support material, which allows the extension 40 to be flexible and have a large deformation space.

[0034] The extension portion 40 has several attaching portions 60. The attaching portions 60 can be fasteners such as Velcro or snap fasteners, all of which are within the scope of this application. During assembly, the extension portion 40 can be attached to the side wall of the rescue helicopter, increasing the waterproof area of ​​the seat cover for the maritime rescue helicopter and preventing seawater leakage.

[0035] The extension section 50 protrudes higher than the side wing 30. The extension section 50 is also made of leather or waterproof material. The extension section 50 and the side wing 30 can be integrally molded or sewn together. The interior of the extension section 50 is also filled with supporting material. The extension section 50 increases the waterproof area of ​​the side wing 30 in height. When the lifeguard is seated in the helicopter seat, the extension section 50 is positioned beside the lifeguard's upper body, preventing corrosion from seawater dripping onto the lifeguard's upper body.

[0036] In some preferred embodiments, the seat cover for the maritime rescue helicopter also includes a bottom curtain 70. Specifically, the bottom curtain 70 is made of leather or other waterproof material. The bottom curtain 70 can be integrally formed with the seat surface 10 or sewn together with it. The bottom curtain 70 increases the waterproof area of ​​the seat cover for the maritime rescue helicopter, preventing seawater leakage to the lifeguard's legs or the floor of the helicopter cabin.

[0037] Preferably, the back of the bottom curtain 70 (the side closest to the helicopter seat) may be provided with a waterproof layer to further improve the waterproof performance of the seat cover for the maritime rescue helicopter.

[0038] Furthermore, the bottom curtain 70 is movably connected to the extension portion 40. Specifically, the extension portion 40 can be adhered to the bottom curtain 70 via the fitting portion 60, further sealing off any space where seawater may leak.

[0039] In some preferred embodiments, the seat cover for the maritime rescue helicopter also includes several seatbelt openings 80. The seatbelt openings 80 are located on the seat back 20 and protrude beyond it, preventing seawater leakage and facilitating the installation and use of seatbelts. Preferably, as... Figure 3 As shown, the opening 81 of the seat belt opening 80 adopts an elastic band tapered design to improve waterproof performance.

[0040] Furthermore, the seatbelt opening 80 is higher than the seat surface 10. Specifically, the seatbelt opening 80 is 60mm-70mm higher than the seat surface 10. This raised design prevents seawater accumulated on the seat surface 10 from leaking into the fuel tank seat of the rescue helicopter through the seatbelt opening 80.

[0041] In some preferred embodiments, the present invention also provides a rescue helicopter with a seat cover for a maritime rescue helicopter having any of the above-mentioned features.

[0042] In summary, the present invention provides a seat cover for a maritime rescue helicopter and a rescue helicopter. Compared with the prior art, the seat cover has side wings filled with supporting material between the seat surface and the backrest, which improves the waterproof performance of the seat cover and prevents seawater from leaking into the fuel tank seat from the side. At the same time, the side wings have extensions that can be bonded to the seat surface and the side wall of the rescue helicopter. This not only makes it compatible with rescue helicopters of different specifications, but also improves the waterproof performance of the seat cover.

[0043] Although this document frequently uses terms such as flanks and extensions, the possibility of using other terms is not excluded. These terms are used merely for the convenience of describing and explaining the essence of this invention; interpreting them as any additional limitation would contradict the spirit of this invention.
