Description

Technical Field

[0001] This utility model relates to the field of automotive seats, specifically a manually adjustable multi-position rear lift automotive seat frame. Background Technology

[0002] Existing car front seats can generally recline flat for passengers to rest. However, due to structural limitations caused by the center of the backrest pivot, when the seat back is fully reclined, the lower back support can cause lumbar compression if the passenger lies down directly. Typically, people would sit forward and then lie down, but this results in a lack of lumbar support. Prolonged lying down can cause pressure on the buttocks and back, leading to soreness and discomfort. With societal development, people are increasingly demanding higher product functionality and user experience. Car usage scenarios are becoming more diverse, and comfort is gradually improving. The number of taxis and ride-hailing vehicles is increasing, and drivers' need to rest in their seats is also growing. While conventional car seats can recline flat, the common lumbar compression issue often requires adding a pad at the connection between the seat cushion and backrest to achieve a flat surface. This results in a poor overall experience and makes it difficult to easily adjust to a comfortable height. Furthermore, the pad must be removed during normal driving to avoid safety concerns.

[0003] Therefore, it is necessary to provide a manually adjustable, multi-position adjustable rear seat frame for automobiles to solve the above-mentioned technical problems. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a manually adjustable multi-level seat cushion rear lift car seat frame.

[0005] This utility model provides a manually adjustable multi-position rear lift car seat frame, including a seat frame assembly and a backrest frame assembly installed behind the seat frame assembly. The inner walls of the two side plates of the seat frame assembly are respectively fixed with a left bracket and a right bracket. An Armrest armrest angle adjuster (a relatively mature existing product, not described in detail here) is installed on the right bracket. A U-shaped lift frame is installed between the left bracket and the right bracket. The pivot of the Armrest armrest angle adjuster is fixedly connected to one end of the U-shaped lift frame.

[0006] Preferably, the U-shaped lifting frame includes a U-shaped rear lifting tube and a left connecting bracket and a right connecting bracket welded and fixed to both ends of the U-shaped rear lifting tube. The right connecting bracket is fixedly connected to the rotating shaft of the Armrest handrail adjuster, and the left connecting bracket is rotatably connected to the left bracket by a step bolt.

[0007] It should be emphasized that a tension strap is installed on the U-shaped lifting frame.

[0008] By rotating the U-shaped rear lift tube, the U-shaped rear lift tube will rotate a certain angle around the pivot of the Armrest handrail angle adjuster installed in the core rotating component. When adjusted to the appropriate angle, the Armrest handrail angle adjuster will be rotated in the reverse direction to lock. It will not rotate when under pressure. When it needs to be restored, simply pull the strap to rotate the lift tube and restore it in the opposite direction.

[0009] Preferably, the U-shaped lifting frame further includes a steel wire fixed inside the U-shaped rear lifting tube, and the steel wire is U-shaped to increase the strength of the U-shaped lifting frame.

[0010] Preferably, the Armrest armrest angle adjuster is fixedly connected to the right bracket by fastening screws, and the left and right brackets are fixed to the side plates of the seat cushion frame assembly by welding, which makes the fixation relatively stable.

[0011] Preferably, both the left and right connecting brackets have an arc-shaped portion at their ends that mates with the U-shaped rear lifting tube, resulting in a better welding effect.

[0012] Compared with related technologies, the present invention provides the following beneficial effects:

[0013] This multi-position adjustable car seat rear lift mechanism can achieve multiple lifting positions and a single reset function for the rear of the seat cushion. End users can adjust the height of the rear of the seat cushion while the seat back is reclined flat, thus solving the common structural problem of the lower back beam "pushing against the waist" and allowing for more comfortable rest. After resting, it can also be reset in one go. The operation is convenient and reliable, and the overall user experience is better. Attached Figure Description

Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please refer to 1- Figure 6 A manually adjustable, multi-position rear-mounted car seat frame mainly consists of a seat cushion frame assembly 2 and a backrest frame assembly 1 located behind it. A left bracket 3 and a right bracket 4 are securely mounted on the inner walls of the two side panels of the seat cushion frame assembly 2, serving as the supporting foundation for the entire structure. Specifically, a mature Armrest armrest adjuster 10 is mounted on the right bracket 4. While the specific working principle of this component will not be elaborated here, it is a key component for achieving the adjustment function.

[0023] A U-shaped lifting frame is cleverly installed between the left support 3 and the right support 4, playing a crucial role in adjusting and raising the seat cushion. This U-shaped lifting frame consists of a U-shaped rear lifting tube 5, a left connecting bracket 6, and a right connecting bracket 7. The two ends of the U-shaped rear lifting tube 5 are respectively welded to the left connecting bracket 6 and the right connecting bracket 7. It is worth noting that the right connecting bracket 7 is tightly connected to the pivot of the Armrest armrest angle adjuster 10, ensuring synchronous rotation; while the left connecting bracket 6 is flexibly rotated to the left support 3 through the step bolt 12, allowing the U-shaped lifting frame to adjust its angle within a certain range.

[0024] To further enhance the stability and strength of the U-shaped lifting frame, a U-shaped steel wire 8 is fixed to the inside of the U-shaped rear lifting pipe 5. This steel wire effectively improves the load-bearing capacity and durability of the overall structure.

[0025] In terms of detailed design, the Armrest armrest adjuster 10 is firmly fixed to the right bracket 4 by fastening screws 11, while the left bracket 3 and the right bracket 4 are firmly welded to the side plate of the seat frame assembly 2 by welding technology. This connection method is not only stable and reliable, but also ensures the sturdiness of the entire seat frame structure.

[0026] In addition, the ends of the left connecting bracket 6 and the right connecting bracket 7 are cleverly designed with arc-shaped parts that match the U-shaped rear lifting tube 5. This design not only improves the convenience of welding, but also ensures the stability and aesthetics of the welded part.

[0027] During use, users can adjust the seat angle simply by rotating the U-shaped rear lift tube 5. Once the desired angle is achieved, the Armrest armrest angle adjuster 10 will lock in the opposite direction, ensuring the seat cushion does not rotate accidentally under pressure. To return to the original position, simply pull the strap gently, and the U-shaped lift frame will rotate in the opposite direction and return to its original position.

[0028] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
