[0003] The technical solution of this utility model is as follows: a mechanical mechanism for linking the position of the rear seat slide rail and the angle of the backrest, comprising: a vehicle body fixing bracket, a connecting rod, a backrest lock, a locking hook, a backrest, a backrest pivot, a seat cushion, a slide rail, and a fixing frame. The vehicle body fixing bracket is fixed to the vehicle. The vehicle body fixing bracket is provided with a slide rail. The connecting rod is slidably connected to the slide rail. The backrest is hinged to the fixing frame through the backrest pivot. The backrest is provided with a backrest lock. The connecting rod is provided with a locking hook. The locking hook is locked to the backrest lock. The connecting rod is hinged to the fixing frame through the backrest pivot. The backrest is hinged to the fixing frame through the backrest pivot. The seat cushion is hinged to the fixing frame. The fixing frame and the slide rail are slidably connected.

[0004] When the mounting bracket reciprocates on the slide rail, it drives the seat cushion and backrest to move simultaneously on the slide rail. At this time, the connecting rod can reciprocate on the slide rail of the vehicle body mounting bracket.

[0005] Furthermore, the end of the connecting rod is provided with a longitudinal protrusion structure, which can slide within the slide.

[0006] The beneficial effects of this utility model are as follows:

[0007] Precise linkage adjustment: Through the mechanical linkage of components such as slide rails, rotating shafts, and connecting rods, the backrest angle can be precisely changed with the movement of the slide rails, and the adjustment process is stable and reliable.

[0008] Simple and reliable structure: It adopts a simple mechanical connection and sliding fit structure, without complex electrical control components, which makes it easy to assemble, highly stable, and convenient for maintenance and manufacturing.

[0009] High adaptability: Designed specifically for rear-seat cars, it can be adapted to the structural characteristics of rear seats in different car models to meet diverse car seat design needs.

[0010] Excellent comfort: The backrest angle can be flexibly adjusted to provide support that conforms to the back of the passenger, effectively optimizing the riding experience and improving comfort. Attached Figure Description

[0018] It should be noted that in the description of this utility model, the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", "clockwise", "counterclockwise", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.

[0019] In this utility model, unless otherwise explicitly specified and limited, the terms "setting," "installing," "connecting," and "joining" should be interpreted broadly. For example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; a connection can be a mechanical connection or an electrical connection; a joint can be a direct connection or an indirect connection through an intermediate medium, and can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0020] A mechanical mechanism linking the position of the rear seat slide rail and the angle of the backrest includes a vehicle body fixing bracket 1, a connecting rod 2, a backrest lock 3, a locking hook 4, a backrest 5, a backrest pivot 6, a seat cushion 7, and a slide rail 8.

[0021] The vehicle body mounting bracket 1 is fixed to the car. The vehicle body mounting bracket 1 is provided with a slide rail 101, and the connecting rod 2 is slidably connected to the slide rail.

[0022] The sliding connection specifically has a longitudinal protrusion 201 at the end of the connecting rod 2. The protrusion 201 can slide within the slide rail 101. This is only one type of sliding connection, and the protrusion 201 is not fixed within the slide rail.

[0023] The backrest 5 and the fixed frame 9 are hinged by the backrest pivot 6. The backrest 5 is provided with a backrest lock 3, and the connecting rod 2 is provided with a locking hook 4. The locking hook 4 is locked and connected with the backrest lock 3. After locking, the connecting rod and the backrest form a fixed whole.

[0024] Link 2 and fixed frame 9 are hinged together by backrest pivot 6.

[0025] The seat cushion 7 is hinged to the fixing frame 9.

[0026] The fixed frame 9 and the slide rail 8 are slidably connected.

[0027] The vehicle body fixing bracket 1 is fixed to the vehicle body, i.e., its relative position is fixed. When the fixing bracket 9 reciprocates on the slide rail 8, it drives the seat cushion 7 and backrest 5 to move simultaneously on the slide rail 8. At this time, the connecting rod 2 can reciprocate on the slide rail 101 of the vehicle body fixing bracket 1, so that the entire backrest 5 can make slight adjustments to the backrest angle according to the movement of the seat cushion. When the slide rail forms adjustment B, the backrest can adjust the angle A in conjunction with the adjustment. See Figure 5 .

[0028] This mechanism employs a mechanical linkage system comprised of a slide rail 8, a seat cushion frame 7, a backrest pivot 6, a connecting rod 2, and a vehicle body support slide rail structure. The slide rail 8 connects to the seat cushion frame 7, while the backrest pivot 6 connects the backrest 5 to the connecting rod 2. When the slide rail 8 moves, the connecting rod 2 rotates around the backrest pivot 6, and its upper end slides within the vehicle body support slide rail, causing a change in the angle of the backrest 5. The backrest 5 can be secured to the connecting rod 2 via a backrest lock 3 and a locking hook 4, thus enabling flexible adjustment of the seat back angle to meet the passenger's desired comfortable seating posture. This mechanism is compatible with rear-seat car seats and can precisely adjust the backrest angle according to different seating habits, enhancing passenger comfort.
