Description

Technical Field

[0001] This utility model relates to the field of seat structure technology, and in particular to a seat structure with a reclining seat cushion. Background Technology

[0002] With the development of automotive technology, people are paying more and more attention to the comfort of car seats. Currently, some front seats have the function of tilting forward, that is, the backrest can be adjusted forward to provide rear passengers with better legroom and leg support for comfortable rest.

[0003] In the prior art, the backrest of the front seat is usually rotated and mounted at the rear end of the seat cushion frame.

[0004] When the backrest rotates forward, there is only rotation between the seat cushion and the backrest, without any other displacement. When the backrest rotates, the seat cushion interferes, preventing it from tilting forward at a large angle, which affects its practicality. Utility Model Content

[0005] The purpose of this utility model is to provide a seat structure with a reclining seat cushion, which aims to solve the problem in the prior art that when the backrest rotates forward, there is only rotation between the seat cushion and the backrest without any other displacement, and the seat cushion interferes with the backrest when it rotates, making it impossible to achieve a large angle of reclining forward, thus affecting its practicality.

[0006] To achieve the above objectives, this utility model provides a seat structure with a reclining seat cushion, including a base frame, a backrest frame, an adjustment assembly, and a reclining assembly. The reclining assembly includes a seat cushion frame, two side arms, two first support members, two second support members, a first angle adjustment motor, a first angle adjuster, and a bottom rail component. The backrest frame is rotatably connected to the base frame and located between the base frame components. The adjustment assembly is connected to both the base frame and the backrest frame. The reclining assembly is connected to the base frame. The seat cushion frame is positioned above the base frame, and the two side arms are movably connected to the seat cushion frame. Located below the seat cushion frame, the first angle adjustment motor is connected to the seat cushion frame, the first angle adjuster is connected to the first angle adjustment motor and located at the output end of the first angle adjustment motor, and the first angle adjuster is rotatably engaged with the two side arm members respectively. The base frame has symmetrical sliding holes, the symmetrical sliding holes are rotatably engaged with the two first support members, the two first support members are rotatably connected to the corresponding side arm members respectively and located on one side of the side arm members, the two second support members are rotatably connected to the base frame and the first angle adjuster respectively, and the bottom rail member is located below the base frame.

[0007] The bottom rail component includes a drive assembly, a slide rod, and a slide rail. The slide rail is located below the base frame. The drive assembly is connected to the base frame and located below the base frame. The slide rod is connected to the slide rail and located above the slide rail, and the slide rod is adapted to the drive assembly.

[0008] The bottom rail component also includes a fixing member, which is detachably connected to the slide rail and located below the slide rail.

[0009] The diving assembly further includes two limiting members, which are fixedly connected to the corresponding first support members and located on one side of the first support members.

[0010] The adjustment assembly includes a second angle adjustment motor and a second angle adjuster. The second angle adjuster is connected to the base frame and the backrest frame, respectively, and the second angle adjustment motor is connected to the second angle adjuster.

[0011] This utility model discloses a seat structure with a reclining seat cushion. In use, the adjustment component receives control signals from the vehicle's electrical system to generate rotational power, thereby adjusting the angle of the backrest frame. Simultaneously, the first angle adjustment motor and the first angle adjuster work together to drive the second support member to rotate around the base frame, causing the seat cushion frame to move forward and recline. At this time, the first support member rotates around the side arm member and moves within the symmetrical sliding hole, realizing the forward movement and reclining of the seat cushion frame. The bottom rail component is used to adjust the overall forward and backward movement of the base frame. In this way, the movement interference caused by the seat cushion rotating on the backrest is avoided, allowing the backrest to fold smoothly onto the seat, achieving a large angle of forward reclining of the backrest, increasing the flexibility of the seat and the usable space in the rear.
