Technical Field

[0001] This application relates to the field of automotive seat technology, specifically to an aviation seat for commercial vehicles with a leg protection structure. Background Technology

[0002] In the design of seats in commercial vehicles, passenger comfort and safety are always the core considerations. As an important component of commercial vehicles, airline-style seats not only need to meet the comfort requirements of long journeys but also need to provide effective physical protection for passengers. Traditional airline-style seats in commercial vehicles typically focus only on support and comfort, using a conventional structure with a frame, foam padding, and leather upholstery. However, existing leg rests lack safety protection for the sides of the legs.

[0003] Therefore, adding protective structures to the sides of the legs to existing leg supports has become a technical problem that the industry urgently needs to solve. Utility Model Content

[0004] In view of this, this application provides an aviation seat for commercial vehicles with a leg protection structure to solve the technical problem that existing leg rests do not have protective structures on both sides and cannot actively protect the passenger's lower legs.

[0005] To achieve the above objectives, this utility model provides the following technical solution: This application provides an aviation seat for commercial vehicles with a leg protection structure, including: A cushion; A leg rest, installed at the front of the seat cushion, includes: A leg support frame is installed on the seat cushion, and the leg support frame consists of a leg support support plate and a pair of leg support side plates. One leg supports are made of foam, and the foam supports are set on the leg support frame; One leg support skin covers the outside of the leg support foam; The leg support plate is equipped with a leg protection device, and the leg protection frame of the leg protection device is welded to the front end of the leg support plate.

[0006] In one alternative embodiment, the leg protection frame includes: A connecting plate is welded to the front end of the leg support plate; A pair of protective baffles are respectively installed on the left and right sides of the connecting plate.

[0007] In one optional embodiment, the leg protection device further includes a pair of protective baffles, which are respectively disposed on the left and right sides of the connecting plate; a protective foam, which is disposed on the outside of the protective baffles; and a protective skin, which covers the outside of the protective foam.

[0008] In one alternative embodiment, the inner end of the protective baffle has an arc-shaped connecting portion, which is connected to the end of the connecting plate.

[0009] In one alternative embodiment, the protective baffle is provided with multiple weight-reducing grooves to reduce weight.

[0010] In one alternative embodiment, the leg support plate and a pair of leg support side plates are integrally formed by stamping.

[0011] In one alternative embodiment, the leg support plate is fixedly connected to a pair of leg support side plates by welding.

[0012] In an alternative embodiment, a headrest is also included, which is detachably attached to the upper end of the backrest.

[0013] As can be seen from the above technical solution, the advantages of this application are: 1. The connecting plate of the leg protection device provided in this application is directly welded to the front end of the leg support plate, so that the leg protection frame and the leg support frame are rigidly connected to form an integrated structure. The protective baffle, protective foam and protective skin can protect the passenger's lower leg, prevent external moving objects from colliding with the lower leg, and reduce the risk of passenger leg injury.

[0014] 2. The protective baffle of this application has multiple hollowed-out grooves, which reduces the weight by about 15%-20%.

[0015] 3. The protective foam of this application uses high-density EPP or PU foam material, which reduces weight while ensuring energy absorption effect. Attached Figure Description

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the embodiments and accompanying drawings. Here, the illustrative embodiments and their descriptions are used to explain this application, but are not intended to limit it.

[0027] refer to Figures 1 to 8 ,like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this application embodiment provides a business vehicle aviation seat with a leg protection structure. The seat mainly consists of a seat cushion 1, a leg rest 2, a backrest 4, and a headrest 5. The leg rest 2 is installed at the front end of the seat cushion 1 and includes a leg rest frame 21, leg rest foam 23, and leg rest cover 22. The leg rest frame 21 is installed on the seat cushion 1 and consists of a leg rest support plate 211 and a pair of leg rest side plates 212. The leg rest foam 23 is disposed on the leg rest frame 21, and the leg rest cover 22 covers the outside of the leg rest foam 23. A leg protection device 3 is provided on the leg rest 2. The leg protection device 3 has a U-shaped structure. When seated, the passenger's lower legs are located within the leg protection device 3, which provides protection for the passenger's lower legs. The leg protection frame 30 of the leg protection device 3 is welded to the front end of the leg rest support plate 211. Both the leg protection frame 30 and the leg support frame 21 are made of cold-rolled carbon steel plates with a thickness of 1.5mm to 3.0mm, formed by stamping or bending, and have good bending stiffness and fatigue strength.

[0028] In some embodiments, to ensure structural strength and ease of production, the leg support plate 211 and a pair of leg support side plates 212 are integrally formed by a stamping process.

[0029] like Figure 2 As shown, a layer of soft leg support foam 23 is provided on top of the leg support frame 21 to provide cushioning for the passenger's calves and ankles. The entire leg support foam 23 is completely covered by the leg support cover 22.

[0030] Preferably, the leg support skin 22 can be made of genuine leather or high-grade artificial leather.

[0031] In some embodiments, such as Figure 4 , Figure 5 As shown, the leg support frame 30 includes a connecting plate 31 and a pair of protective baffles 32. The connecting plate 31 is welded to the front end of the leg support plate 211, thereby firmly fixing it to the front edge of the leg support plate 211. The pair of protective baffles 32 are respectively arranged on the left and right sides of the connecting plate 31, which can provide good protection for the passenger's lower legs and prevent moving objects on the outside of the seat from colliding with the passenger's lower legs.

[0032] In some embodiments, such as Figure 4 , Figure 5 As shown, the connecting plate 31 is a plate adapted to the leg support plate 211. The length h of the leg support plate 211 is three times the width d of the connecting plate 31. The protective baffle 32 consists of a pair of vertically upward plates, respectively located at the left and right ends of the connecting plate 31. Their inner ends are smoothly connected to the ends of the connecting plate 31 via an arc-shaped connecting part 35. The arc-shaped connecting part 35 not only enhances the structural strength but also avoids sharp edges, thus making it safer.

[0033] In some embodiments, such as Figure 5 and Figure 6 As shown, the leg protection device 3 also includes protective foam 33 and protective skin 34. The protective foam 33 is disposed on the outside of the protective baffle 32. The protective skin 34 covers the outside of the protective foam 33.

[0034] To ensure comfortable contact with the sides of the passenger's legs, a protective foam 33 is attached to the outside of the protective baffle 32, and the outer layer of the foam is then wrapped with a protective skin 34 of the same material as the leg support skin 22.

[0035] Preferably, such as Figure 7 and Figure 8 As shown, the protective baffle 32 is provided with multiple weight-reducing grooves 36 to reduce weight. The multiple weight-reducing grooves 36 are arranged longitudinally or laterally at intervals, which effectively reduces the total weight while ensuring the protective strength.

[0036] When a passenger is seated, the leg protection device 3 located on the leg rest 2 effectively restricts the passenger's lower leg, preventing impact from moving objects on the outside. Additionally, when the vehicle turns or encounters bumps, it effectively limits the lateral sliding of the passenger's lower leg, providing extra lateral support and protection. Therefore, this leg protection device 3 enhances the passenger's sense of security and stability during the journey.

[0037] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to the embodiments of this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
