[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0019] In this embodiment, as Figures 1 to 3 As shown, a lightweight passenger seat with a foldable seat cushion includes a slide rail assembly, on which a seat base assembly is slidably mounted. A seat cushion assembly and a backrest assembly are mounted on the seat base assembly. The backrest assembly is angled via a backrest angle adjustment assembly located on its outer side. The seat cushion assembly is rotated via a seat cushion folding locking structure located on its outer side. Both the seat cushion assembly and the backrest assembly are constructed from an internal frame and a flexible material covering the internal frame.

[0020] In this embodiment, the backrest angle adjustment component adopts existing technology, including an unlocking handle, a pull cable, and other related mechanisms to realize the backrest angle adjustment function, providing passengers with different backrest angles. Furthermore, a single pull cable is used for backrest angle adjustment, reducing costs. The unlocking handle is the part of the backrest angle adjustment component that the user can directly operate. When you need to adjust the backrest angle, you can activate the adjustment mechanism by flipping or pressing the unlocking handle. It is usually designed in a location easily accessible to the user, such as the side of the seat. Its function is to send an unlocking signal to the entire adjustment system, allowing the backrest to change from its current fixed angle state to an adjustable state. The pull cable plays the role of transmitting force and movement in the backrest angle adjustment component. When the unlocking handle is operated, it pulls the pull cable. One end of the pull cable is connected to the unlocking handle, and the other end is connected to a key part of the adjustment mechanism. It acts like a bridge, transmitting the user's operation from the unlocking handle to the relevant mechanisms. The pull cable generally has a certain strength and flexibility, enabling it to accurately transmit force within different angles and spatial ranges, ensuring smooth and reliable backrest angle adjustment.

[0021] This component typically consists of meshing gears and racks. When the cable is pulled, it triggers the rotation of the gears, which in turn moves the meshing rack. The rack's movement changes the backrest angle. The gear and rack design provides precise angle adjustment and can withstand a certain amount of force, ensuring the backrest remains stable at different angles. After the backrest angle is adjusted, a locking mechanism secures it. When the unlocking handle is released, the locking mechanism automatically locks, preventing the backrest from accidentally changing angle during use. The locking mechanism usually employs a mechanical latch, cam lock, or other reliable locking methods to ensure the backrest maintains a stable angle under various usage conditions. Springs and dampers play an auxiliary role in the backrest angle adjustment process. Springs provide a certain amount of rebound force, making the backrest adjustment smoother. Dampers control the speed of backrest movement, preventing the backrest from moving too quickly or abruptly during adjustment, improving safety and comfort. The backrest angle adjustment component achieves flexible adjustment of the seat backrest angle through the coordinated work of the unlocking handle, cable, and related mechanisms. This component is widely used in various types of seating, such as car seats, office chairs, and airplane seats, providing users with a more comfortable and personalized seating experience.

[0022] The seat cushion folding and locking structure adopts a push-push locking mechanism, a relatively advanced and convenient design solution for achieving the seat cushion flipping function. This mechanism typically works by pressing a specific part of the seat cushion to trigger the internal locking and unlocking mechanism. When it is necessary to flip the seat cushion, simply rotating the seat cushion assembly easily achieves the locking and unlocking functions.

[0023] The pre-installed mounting positions on the backrest frame ensure accurate installation and secure fastening of the push-push locking mechanism. This design allows for a tighter and more stable connection between the seat cushion and backrest, while also facilitating installation and maintenance. The pre-installed mounting positions require precise design and measurement to ensure a perfect fit between the locking mechanism and the latch mechanism on the seat cushion frame, achieving reliable locking and unlocking.

[0024] Welding the corresponding locking tongue mechanism onto the seat cushion frame is a crucial step in enabling the seat cushion's flip-up function. The locking tongue mechanism works in conjunction with the push-push locking mechanism, locking and unlocking the seat cushion through rotation of the seat assembly. Welding the locking tongue mechanism ensures a secure and reliable connection to the seat cushion frame, preventing loosening or detachment during use. Simultaneously, the welding process guarantees the positioning accuracy of the locking tongue mechanism, allowing it to precisely engage with the locking mechanism on the backrest frame.

[0025] This design utilizes a push-push locking mechanism, with pre-installed mounting positions on the backrest frame and a corresponding locking tongue welded to the seat cushion frame, enabling the seat cushion to flip. This design not only improves the ease of use and comfort of the seat but also enhances its functionality and practicality.

[0026] In one or more embodiments of this utility model, the seat base assembly includes two opposing support sheet metals 1 fixed to the slide rail assembly. Two bottom crossbeams 2 are fixed between the lower ends of the two support sheet metals 1. Outer support rods 3 are fixed to the outer sides of the support sheet metals 1 respectively. A top crossbeam 4 is fixed between the two outer support rods 3. A connecting rod 5 is also fixed to the upper side of the two outer support rods 3. A backrest angle adjustment assembly is provided on the outer side of the outer support rods 3. The backrest assembly is hinged to the backrest angle adjustment assembly. The seat cushion folding locking structure is installed on the inner side of the backrest angle adjustment assembly. The seat cushion assembly is installed on the movable end of the seat cushion folding locking structure.

[0027] In this embodiment, the seat base assembly consists of a supporting sheet metal, a bottom crossbeam, outer support rods, a top crossbeam, and connecting rods, providing stable support for the seat. The backrest assembly and seat cushion assembly are connected to the seat base assembly via a backrest angle adjustment assembly and a seat cushion folding locking structure, respectively, ensuring a secure and reliable connection.

[0028] In one or more embodiments of this utility model, the internal frame includes a seat frame 6 and a backrest frame 7, which are formed by enclosing and fixing with round tubes. The internal frame is formed by a plurality of welded steel wires 8 to form a crisscrossing support network.

[0029] In this embodiment, the seat cushion frame 6 and backrest frame 7 adopt a structure of round tubes combined with welded steel wires. While ensuring the strength of the seat and meeting the requirements of riding comfort, the weight of the seat cushion frame is reduced, thereby achieving a lightweight design. Furthermore, the single-adjustment mechanism structure is adopted, which also reduces costs.

[0030] In one or more embodiments of this utility model, the flexible material is a foamed material, which is made into a corresponding shape and then fitted onto the internal skeleton; a cover 9 is also fitted over the foamed material.

[0031] In this embodiment, the use of foam material and seat cover 9 makes the seat more comfortable.

[0032] In one or more embodiments of this utility model, an outer plate 10 is fixed to the outer side of the outer support rod 3, and connecting plates 11 are fixed to both sides of the backrest frame 7. The upper end of the outer plate 10 is hinged to the lower end of the connecting plate 11. The backrest angle adjustment component is fixed to the outer side of the outer plate 10, and the angle of the backrest frame 7 is adjusted by the backrest angle adjustment component.

[0033] In one or more embodiments of this utility model, an inner side plate 12 is mounted on the inner side of the outer side plate 10 via a pivot, and the seat cushion frame 6 is fixed to the lower side of the inner side plate 12.

[0034] In this embodiment, the seat cushion folding and locking structure allows users to easily rotate the seat cushion assembly to lock and unlock the seat cushion, providing convenience for users to place larger items in the front passenger seat.

[0035] In one or more embodiments of this utility model, a socket 13 for inserting a three-point seat belt is provided on the outer side of one of the outer side plates 10. The provision of a three-point seat belt socket on the outer side of the outer side plate provides safety assurance for the front passenger.

[0036] The slide rail assembly is connected to the seat base assembly and the vehicle body respectively, and the slide rail can be manually unlocked when the passenger is seated. The slide rail assembly adopts existing technology and includes a base frame. Two opposing fixed seats 14 are fixed on the base frame. A sliding bracket 15 is slidably arranged on the fixed seats. A locking structure is provided on the inner side of the sliding bracket. The relative position between the sliding bracket and the fixed seats is locked by the locking structure. The locking structure is driven by the unlocking handle 16.

[0037] In this embodiment, force is transmitted to the unlocking handle, causing the unlocking handle to drive upward, separating the fixed point between the sliding bracket and the fixed base, allowing the sliding bracket to move along the length of the fixed base, thus achieving the purpose of unlocking.

[0038] The locking structure includes an unlocking tooth 17 rotatably disposed inside the sliding bracket. The inner side of the extended end of the unlocking tooth has an inwardly bent locking plate. The locking plate has several locking holes. The edge of the fixed seat has several fixing teeth. By engaging and disengaging the fixing teeth with the locking holes, the locking and unlocking states between the sliding bracket and the fixed seat are controlled.

[0039] In this embodiment, the unlocking tooth is an integrally formed structure, which is a long strip plate-shaped structure with a rotating shaft forming on its inner side. The sliding bracket has a circular hole on its inner side, and the rotating shaft is rotatably disposed in the circular hole. The unlocking tooth rotates around the rotating shaft as a fulcrum. The fixing seat is an integrally formed structure, which is a long strip plate-shaped structure. Both sides of its length direction are first bent upward at 90 degrees, and the edges of the bent ends are bent again. Several rectangular grooves are formed on its edges, and a rectangular groove is formed between two of the tooth pieces. The opening of the rectangular groove is downward.

[0040] In one or more embodiments of this utility model, a fixing block is formed on the inner side of the unlocking tooth, and the inner end of the unlocking handle is sleeved and fixed on the fixing block.

[0041] In this embodiment, the rear end of the unlocking tooth plate forms two tail cones, which are bent inward at a 90-degree angle, forming a groove between the two tail cones. The inner end of the unlocking handle extends through the groove toward the fixing block. A retaining seat is also fixed to the inner side of the unlocking tooth plate. The retaining seat is located between the groove and the fixing block and is also used to fix the unlocking handle. Through the cooperation of the groove, the fixing block, the retaining seat, and the unlocking handle, the unlocking handle can better drive the unlocking tooth plate to rotate, and the rotation controls the engagement and disengagement of the retaining tooth plate with the lock hole.
