[0018] To make the embodiments of this application clearer, they will be described below in conjunction with the accompanying drawings. It should be understood that the content mentioned below represents only some embodiments of this application, and not all embodiments are listed exhaustively. Therefore, other embodiments that can be obtained based on the following embodiments without any inventive effort fall within the protection scope of this application.

[0019] It should be understood that the terminology used herein is for the purpose of describing specific embodiments only and is not intended to impose strict limitations on the technical solutions unless the context clearly indicates otherwise. For example, the use of "a," "an," and "the" to modify a feature does not preclude the possibility that the feature may be plural in other embodiments.

[0020] It should be understood that the terms "comprising," "including," and "having" are open-ended, indicating the presence of the stated features but not excluding the possibility of other features in the embodiment. Similarly, the use of terms such as "first," "second," etc., to describe multiple features only indicates the distinction between one feature and another, and such terms do not imply order or sequence unless explicitly stated in the context.

[0021] It should be understood that, unless the context clearly indicates otherwise, the terms "setup," "connection," and "installation" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integrated connection; they can refer to a direct connection or an indirect connection via a medium. Those skilled in the art will understand the specific meaning of these terms in this document based on the specific circumstances.

[0022] In addition, for ease of description, the text will use terms of spatial relative relationship to describe the position of one feature relative to another feature, such as "inner", "outer", "end", "side", "upper", "middle", "lower", "high", "low", "axial", "circumferential", "radial", "horizontal", "vertical", "first direction", "second direction", etc. It can be understood that the spatial relative relationship between two features should include other specific situations besides those shown in the accompanying drawings of the specification.

[0023] The embodiments of this application are described below with reference to the accompanying drawings. It can be understood that the technical features involved in the different embodiments described below can be combined with each other as long as they do not conflict with each other.

[0024] Firstly, referring to Figures 1 to 6 This application discloses a seating system, comprising a first aspect, a seat cushion, a backrest, armrests, a linkage, and a seatbelt buckle. The backrest is connected to the seat cushion, the armrests are located on the backrest, and the backrest can rotate the armrests in a direction closer to the seat cushion. The seatbelt buckle is connected to the seat cushion and located below the armrests. The seat cushion includes a first part and a second part, the first part being located above the second part and movable relative to the second part in a direction away from the backrest. The linkage is located between the seat cushion and the seatbelt buckle, and when the first part moves away from the backrest, the linkage rotates the seatbelt buckle in a direction away from the armrests.

[0025] In this embodiment, when the first part of the seat cushion moves away from the backrest, the linkage drives the seat belt buckle to rotate away from the armrest, thereby avoiding the armrest. This ensures that when the backrest moves the armrest closer to the seat cushion, the seat belt buckle and the armrest will not interfere with each other, which is beneficial for the backrest to fold forward and lie flat. This application has a simple structure, low cost, reliable control, and improved convenience.

[0026] Specifically, the first part can move away from the backrest relative to the second part, i.e., slide forward, to achieve the functions of "seat cushion extension" or "seat depth adjustment," improving riding comfort and accommodating users of different body sizes. It also provides motion input for subsequent linkage components to achieve their functions. Furthermore, the backrest drives the armrest to rotate towards the seat cushion, indicating that the backrest can tilt forward, for example, to achieve "movie viewing mode" or "getting on / off mode." The armrest then presses down, expanding the entry and exit space for easier passenger (especially children or the elderly) getting on and off the vehicle, and facilitating integration with projection equipment to enhance the viewing experience. Moreover, the seatbelt buckle is located below the armrest and can rotate relative to the seat cushion. This avoids the risk of the buckle being suspended or exposed, resulting in a high degree of integration. The linkage connects the seat cushion and the seatbelt buckle; when the first part moves forward, it triggers the seatbelt buckle to move away from the armrest, effectively avoiding the downward pressure path of the armrest. Specifically, this prevents the armrest from pressing on the seatbelt buckle when the backrest tilts forward, causing jamming or damage, and also prevents the seatbelt buckle from leaving indentations on the armrest.

[0027] Optionally, the seating system in this embodiment is applicable to the front seats, second-row seats, third-row seats, etc. in a vehicle.

[0028] In some embodiments, refer to Figures 2 to 5 The linkage includes a first connecting part, an elastic part, and a second connecting part. The first connecting part is connected to the seat cushion, the second connecting part is connected to the seat belt buckle, and the elastic part is located between the first connecting part and the second connecting part.

[0029] In this embodiment, the linkage includes an elastic part, which allows it to have a certain buffering and reset capability to absorb impact force and prevent damage to parts caused by rigid transmission; it also supports an automatic reset function, and understandably, it works better in conjunction with the elastic reset part described later; in addition, the elastic part can improve the system durability and the smoothness of transmission.

[0030] In some embodiments, refer to Figure 4 and Figure 5 The first connecting part is connected to the first part, and the first part can drive the seat belt buckle to rotate through the linkage.

[0031] In this embodiment, the first connecting part is connected to the first part, that is, the first part moves forward, which will directly pull the linkage, thereby driving the lock to rotate, resulting in rapid response and high transmission efficiency.

[0032] In some embodiments, refer to Figures 1 to 3 The first connecting part is connected to the second part; the first part is provided with a limiting part. Under the initial working condition, the limiting part abuts against the seat belt buckle, and the elastic part has an elastic force on the seat belt buckle to move it away from the armrest; when the first part moves away from the backrest, the limiting part disengages from the seat belt buckle, and the elastic part drives the seat belt buckle away from the armrest.

[0033] In this embodiment, when the first part is in the initial state, the limiting part abuts against the seat belt buckle to prevent it from rotating. At this time, the elastic part is preloaded with elastic force, which makes the seat belt buckle tend to rotate forward. When the first part moves forward, the limiting part disengages from the seat belt buckle. At this time, the elastic part releases energy, thereby driving the buckle to rotate forward quickly, realizing "trigger-type" automatic pop-out, improving convenience and practicality.

[0034] In some embodiments, refer to Figures 2 to 5 The seatbelt buckle includes a lock body, a connecting rod, and a protective sleeve. The lock body is located at one end of the connecting rod, and the other end of the connecting rod is rotatably connected to the seat cushion. The protective sleeve covers at least part of the connecting rod. The second connecting part includes a hook structure, which is hooked onto the outside of the protective sleeve.

[0035] In this embodiment, the protective sleeve covers the connecting rod, serving to prevent dust, corrosion, and noise, and also enhancing the overall quality. Furthermore, the hook structure is located on the outside of the protective sleeve, facilitating easy installation and disassembly, improving maintainability, and simultaneously increasing the friction between the second connecting part and the connecting rod, preventing relative sliding and ensuring a secure connection. It also reduces frictional noise and prevents damage to the connecting rod from the hook structure, thus providing protection. This embodiment has a simple structure, requires no screws for fastening, and reduces costs.

[0036] In some embodiments, refer to Figure 6 The seating system also includes a drive unit connected between the first part and the second part, which can drive the first part to move relative to the second part.

[0037] In this embodiment, the drive unit connects the first part and the second part, and can drive the seat cushion to extend or retract electrically or manually. The control is reliable, the seat space is increased, and it is suitable for a variety of cabin scenarios.

[0038] In some embodiments shown in the figures, the seat system also includes a resilient reset member disposed between the seat cushion and the seat belt buckle; when the first portion approaches the backrest, the resilient reset member drives the seat belt buckle to rotate toward the armrest.

[0039] In this embodiment, when the first part retracts and approaches the backrest, the elastic reset member pulls the seat belt buckle to rotate towards the armrest, that is, retracts it to its original position, thereby ensuring that the seat belt buckle is in an easily accessible position when in a normal sitting posture, forming a complete "extend-retract" cycle and realizing closed-loop control.

[0040] Optionally, the elastic reset element is a torsion spring.

[0041] In some embodiments, refer to Figure 3 and Figure 5When the seatbelt buckle is turned away from the handrail, the seatbelt buckle is lower than the top surface of the first part.

[0042] In this embodiment, the seat belt buckle will not be higher than the seat cushion surface after rotation, so that the backrest and seat cushion can fit more closely after the backrest is folded forward, avoiding interference between the backrest side wings and the seat belt buckle, which is conducive to the backrest being laid flat; at the same time, it can prevent the passenger's legs from being bumped by the buckle, ensure the seat cushion edge is flat, and improve comfort.

[0043] In some embodiments not shown in the figures, when the first portion moves away from the backrest, the first portion extends beyond the second portion and forms an overhang; when the backrest rotates the armrest in a direction close to the seat cushion, the armrest corresponds to the overhang.

[0044] In this embodiment, the armrest, when pressed down, faces the extended area of ​​the seat cushion, forming a continuous support surface visually and structurally, guiding the user to sit correctly, while enhancing the overall sense of unity and design aesthetics. It can also serve as an auxiliary support reference position for other devices, such as when installing a child safety seat.

[0045] Secondly, this application proposes a vehicle that includes the seating system of the first aspect.

[0046] In this embodiment, the vehicle of the second aspect includes the seating system of the first aspect, and therefore the vehicle of the second aspect includes all the technical effects of the seating system of the first aspect.

[0047] It should be noted that, in addition to the seating system, the vehicle may also include tires, hydraulic pumps, engines, etc. Other components will not be described in detail.

[0048] Optionally, the vehicle may be a new energy vehicle, a fuel vehicle, a hybrid vehicle, or a flying car.

[0049] In particular, the term "and / or" in this application should be understood as follows: In the first case, the term “and / or” between the first subject and the second subject includes any of the following meanings: (1) only the first subject; (2) only the second subject; and (3) both the first subject and the second subject.

[0050] In the second case, the term "and / or" between the last two of three or more subjects means including at least one of the subjects. For example, "first subject, second subject and / or third subject" has the same meaning as "first subject and / or second subject and / or third subject", specifically including the following combinations: (1) only the first subject; (2) only the second subject; (3) only the third subject; (4) first subject and second subject and no third subject; (5) first subject and third subject and no second subject; (6) second subject and third subject and no first subject; and (7) first subject, second subject and third subject; Furthermore, the character " / " in this application indicates that the objects before and after it are in an "or" relationship.

[0051] Finally, although the embodiments of this application have been described above in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the concept of this application, and such modifications and variations all fall within the scope of protection of this application.
