Description

Technical Field

[0001] This utility model relates to the field of automotive seat design technology, and in particular to an automotive seat backrest with a lateral support reinforcement structure. Background Technology

[0002] The car seat backrest is a core component of the car seat, mainly used to support the back and torso of the occupant, providing basic support and comfort during the driving and riding process. At the same time, it helps to fix the occupant's body under conditions such as vehicle movement, turning, and braking, ensuring riding safety. Therefore, a car seat backrest with a lateral support reinforcement structure is needed. Car seat backrests with reinforced lateral support are upgraded products based on traditional seat backrests, with the addition of dynamically adjustable lateral support components. Previous car seat backrests had rigid lateral support structures that lacked elasticity and adjustability. Smaller passengers could not get enough support, while larger passengers would feel restricted. Some simple lateral supports relied only on foam padding, which was not strong enough to prevent body shift when cornering or braking suddenly, affecting driving safety and comfort. Utility Model Content

[0003] To overcome the above shortcomings, this utility model provides a car seat backrest with a lateral support reinforcement structure, which aims to improve the problem that rigid lateral support structures lack elasticity and adjustability, making it difficult for slender occupants to obtain sufficient support, while occupants with larger builds will feel restricted.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a car seat backrest with a lateral support reinforcement structure, comprising a lateral support plate, a backrest bracket and a ball cup fixedly connected to the outer wall of the lateral support plate, a ball head rotatably connected inside the ball cup, a telescopic cylinder fixedly connected to the ball head, a connecting plate fixedly connected to the outer wall of the telescopic cylinder, a spring disposed inside the telescopic cylinder, one end of the spring fixedly connected to the outer wall of the ball head, the other end of the spring fixedly connected to the outer wall of the connecting plate, and an adjustment assembly disposed inside the lateral support plate.

[0005] Preferably, the adjustment assembly includes a connecting shaft, the outer wall of which is fixedly connected to the interior of a lateral support plate, and an angle adjuster is fixedly connected to the outer wall of the connecting shaft.

[0006] Preferably, a fixing plate and a telescopic rod are fixedly connected to the outer wall of the first lateral support plate, and a connecting block and a second connecting shaft are fixedly connected to the upper surface of the fixing plate.

[0007] Preferably, the connecting block is rotatably connected to a roller, the outer wall of the connecting shaft is rotatably connected to a lateral support plate, and the outer wall of the lateral support plate is fixedly connected to the outer wall of the telescopic rod.

[0008] Preferably, the outer wall of the telescopic rod is provided with a second spring.

[0009] Preferably, one end of the second spring is fixedly connected to the outer wall of the first lateral support plate, and the other end of the second spring is fixedly connected to the outer wall of the second lateral support plate.

[0010] Preferably, a winding roller is fixedly connected to the outer wall of the connecting shaft, and a steel wire rope is fixedly connected to the outer wall of the winding roller.

[0011] Preferably, the outer wall of the wire rope is fixedly connected to the outer wall of the second lateral support plate, and the outer wall of the wire rope is disposed on the outer wall of the roller.

[0012] This utility model has the following beneficial effects: 1. In this utility model, when the occupant's body is compressed by the centrifugal force generated by the vehicle's own weight or the vehicle's cornering, the pressure is directly transmitted to the spring, which in turn causes the ball head to rotate flexibly on the inner wall of the ball cup. At the same time, it causes the telescopic cylinder and the spring to compress synchronously. With the help of the elastic reaction force of the spring, the connecting plate can be pushed to fit tightly against the occupant's torso curve. Through this dynamic adaptation process, the angle of the connecting plate can be adjusted in real time. This achieves the effect of automatically and finely adjusting the support angle and force according to the differences in body shape, sitting posture, and force conditions of different occupants, effectively alleviating the discomfort caused by body swaying during driving.

[0013] 2. In this utility model, by rotating the angle adjuster handle, the passenger tilts the side support plate one and the backrest bracket backward. The connecting shaft rotates accordingly, driving the winding roller to rotate. The winding roller pulls the steel wire rope to slide along the roller, causing the side support plate two to rotate around the connecting shaft towards the occupant's body and retract. At the same time, the spring two and the telescopic rod are stretched, providing enhanced lateral support and a sense of enclosure. When the backrest is adjusted back to an upright angle, the angle adjuster and the connecting shaft rotate in opposite directions, the winding roller rotates back to release the tension, and the spring reaction force drives the side support plate two to rotate outward to reset, restoring the relaxed state. This achieves the effect of facilitating getting in and out of the vehicle and ensuring daily driving comfort, thus improving comfort. Attached Figure Description

Detailed Implementation

[0016] 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 embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0017] Reference Figure 1 , Figure 2 and Figure 3 An embodiment of this utility model provides: a car seat backrest with a lateral support reinforcement structure, including a lateral support plate 1, a backrest bracket 2 and a ball cup 3 fixedly connected to the outer wall of the lateral support plate 1, a ball head 4 rotatably connected inside the ball cup 3, a telescopic cylinder 5 fixedly connected to the ball head 4, a connecting plate 6 fixedly connected to the outer wall of the telescopic cylinder 5, a spring 7 provided inside the telescopic cylinder 5, one end of the spring 7 fixedly connected to the outer wall of the ball head 4, and the other end of the spring 7 fixedly connected to the outer wall of the connecting plate 6, and an adjustment component provided inside the lateral support plate 1; Specifically, the lateral support plate 1 is fixedly connected to the backrest bracket 2 and the ball cup 3, serving as a load-bearing support and connecting core components. This provides a stable foundation for the lateral support function of the seat back and an initial support surface for the occupant's torso, ensuring structural stability and basic support. The ball cup 3 and ball head 4 are connected by rotation, transmitting pressure and adjusting the angle. When the occupant's body presses against the lateral support plate 1, the pressure is transmitted through the transmission, causing the ball head 4 to rotate flexibly on the inner wall of the ball cup 3, thus adapting to the direction of force on the occupant's body. This allows the support structure to adjust synchronously with body movements. The telescopic cylinder 5 connects the ball head 4 and the connecting plate 6, along with the internal spring 7, to buffer pressure and provide elastic recovery. The pressure applied by the occupant's body compresses the telescopic cylinder 5 and the spring 7, and the reaction force of the spring 7 causes the connecting plate 6 to conform to the occupant's torso, automatically fine-tuning the angle of the connecting plate 6. This achieves a close fit to the body curve and improves the support fit. The effect of the connecting plate 6, which directly contacts the occupant's torso, is to disperse lateral pressure and evenly transmit the concentrated force applied by the body to the telescopic cylinder 5 and spring 7, avoiding excessive local stress. This reduces the feeling of pressure on the body and improves riding comfort. The synergistic action of the ball joint 4, telescopic cylinder 5, and spring 7 dynamically adapts to body movements. Whether the occupant is in a normal sitting posture or under the centrifugal force when the vehicle is cornering, it can quickly respond to changes in body posture, causing the connecting plate 6 to adjust its angle and support strength. This achieves real-time micro-adjustment based on the occupant's body curve and enhances lateral support stability. Through the linkage of various components, the lateral support strength of the seat back is strengthened, and through elastic buffering and automatic angle micro-adjustment, it adapts to occupants of different body types and responds to changes in body posture during vehicle movement. This reduces body sway, improves riding safety and comfort, and ensures the stability of the occupant's torso during driving, adapting to the complex working conditions required during vehicle operation.

[0018] Reference Figure 1 and Figure 2 The adjustment assembly includes a connecting shaft 9, the outer wall of which is fixedly connected to the inside of the lateral support plate 1, and an angle adjuster 8 is fixedly connected to the outer wall of the connecting shaft 9. Specifically, the connecting shaft 9 of the adjustment component is fixed inside the side support plate 1, which serves to install and fix the angle adjuster 8. The angle adjuster 8 provides a basis for the overall angle adjustment of the seat back. With the automatic fine-tuning function of the side support structure, it achieves the effect of taking into account both the overall adjustment of the backrest and the local side adaptation.

[0019] Reference Figure 1 , Figure 2 and Figure 4A fixed plate 14 and a telescopic rod 18 are fixedly connected to the outer wall of the lateral support plate 1. A connecting block 12 and a connecting shaft 15 are fixedly connected to the upper surface of the fixed plate 14. A roller 13 is rotatably connected inside the connecting block 12. A lateral support plate 16 is rotatably connected to the outer wall of the connecting shaft 15. The outer wall of the lateral support plate 16 is fixedly connected to the outer wall of the telescopic rod 18. A spring 17 is provided on the outer wall of the telescopic rod 18. Specifically, the lateral support plate 11 is fixedly connected to the fixed plate 14 and the telescopic rod 18, serving to support the connecting block 12, the connecting shaft 15, and the lateral support plate 16. This provides a stable installation foundation for the adjustment function of the lateral support, ensuring that all components work together without deviation, thus achieving the effect of ensuring the stability of the structure adjustment. The connecting block 12 on the fixed plate 14 supports the roller 13, guiding the steel wire rope 11 to slide, reducing the frictional resistance when the steel wire rope 11 is pulled, and making the rotation adjustment of the lateral support plate 16 smoother. This improves the adjustment flexibility and reduces component wear. The lateral support plate 16 is rotatably connected to the connecting shaft 15. Support plate 2 16 serves as a pivot point for the lateral support plate 2 16, allowing it to open and close flexibly around the connecting shaft 2 15. Combined with the telescopic guide rod 18, it ensures the precise movement trajectory of the lateral support plate 2 16, achieving the effect of stably closing or opening the lateral support structure. The telescopic rod 18 connects the lateral support plate 1 and the lateral support plate 2 16, and the spring 2 17 on the outer wall provides elastic support and reset. When the lateral support plate 2 16 closes, it stretches the spring 2 17 and the telescopic rod 18. After releasing the tension, the reaction force of the spring 2 17 causes it to reset, achieving automatic restoration to a relaxed state and facilitating getting on and off the vehicle.

[0020] Reference Figure 1 , Figure 2 and Figure 4 One end of spring 17 is fixedly connected to the outer wall of lateral support plate 1, and the other end of spring 17 is fixedly connected to the outer wall of lateral support plate 16; a winding roller 10 is fixedly connected to the outer wall of connecting shaft 9, and a wire rope 11 is fixedly connected to the outer wall of winding roller 10; the outer wall of wire rope 11 is fixedly connected to the outer wall of lateral support plate 16, and the outer wall of wire rope 11 is set on the outer wall of roller 13; Specifically, the winding roller 10 is fixed by the connecting shaft 9, which transmits rotational power. When the angle adjuster 8 drives the connecting shaft 9 to rotate, the winding roller 10 rotates synchronously and winds the steel wire rope 11, applying tension to the steel wire rope 11. This provides power for the lateral support plate 16 to retract. The steel wire rope 11 connects the winding roller 10 and the lateral support plate 16, transmitting tension. Guided by the roller 13, the lateral support plate 16 is pulled to rotate towards the occupant's body, enhancing the lateral support and improving occupant stability when the vehicle is cornering or tilting. Through the linkage between the angle adjuster 8 and the winding roller 10, the lateral support plate 16 retracts and returns to its original position, providing reinforced support when the backrest is tilted and restoring a relaxed state when the backrest is upright. This adapts to different seating scenarios, achieving a balance between safety and comfort, and facilitating occupant entry and exit. The lateral support of the seat can be dynamically adjusted according to the backrest angle, adapting to various driving conditions.

[0021] Working principle: When the occupant's body is compressed by the lateral support plate 1 due to weight or centrifugal force during bending, the pressure will act on the spring 7, which in turn will drive the ball head 4 to rotate on the inner wall of the ball cup 3, compressing the telescopic cylinder 5 and the spring 7. The reaction force of the spring 7 will drive the connecting plate 6 to conform to the curve of the occupant's torso, thereby adjusting the angle of the connecting plate 6. This achieves the effect of automatically fine-tuning the support plate and angle according to the occupant's body curve. When the passenger rotates the angle adjuster 8 handle, causing the lateral support plate 1 and backrest bracket 2 to tilt backward, the connecting shaft 9 rotates accordingly. The winding roller 10, fixed to the connecting shaft 9, also rotates. The rotation of the winding roller 10 applies tension to the wire rope 11, causing it to slide against the outer wall of the roller 13. Under this tension, the lateral support plate 16 rotates around the connecting shaft 15 towards the passenger's body, retracting inward. Simultaneously, it stretches the spring 17 and the telescopic rod 18, providing enhanced lateral support and a sense of enclosure. When the passenger adjusts the backrest back to an upright position, the angle adjuster 8 and the connecting shaft 9 rotate in opposite directions, causing the winding roller 10 to rotate back to its initial position. The rotation of the winding roller 10 releases the tension on the wire rope 11, and the reaction force of the spring 17 drives the side support plate 16 to reset, causing the side support plate 16 to rotate outward and return to a relaxed state, making it easier to get on and off the vehicle and providing a comfortable driving experience. This also serves to adjust the side support plate 16, achieving the effects of enhanced lateral support and a sense of enclosure, making it easier to get on and off the vehicle and providing a comfortable driving experience.
