Description

Technical Field

[0001] This application relates to the field of automotive seat technology, specifically to a flame-retardant and noise-absorbing back panel structure for automotive seats. Background Technology

[0002] Car seats are an important part of car interiors, providing not only a comfortable riding experience for drivers and passengers but also playing a crucial role in ensuring driving safety. Car seats come into direct contact with the human body, and their design, materials, and functions all affect the comfort, safety, and long-term health of passengers. The car seat backrest is an important component of the car seat, and its design, materials, and functions directly affect passenger comfort, safety, and the efficiency of interior space utilization. The design of the car seat backrest has evolved from a single structural component into an integration of safety, functionality, comfort, and intelligence, making it a key structure in car seat design.

[0003] Existing car seat back panel structures typically include a back panel, headrest panel, side panel, and hanging panel. The hanging panel can be used as a rear seat hook, making it highly practical. The seat back panel, headrest panel, and side panel are made as a single piece, ensuring strong stability and resistance to deformation.

[0004] The aforementioned structure reduces the cost of car seat manufacturing through its one-piece panel design. However, the production of one-piece car seat back panels typically requires mold making, and each seat design necessitates a separate mold, resulting in high costs for each mold. Furthermore, the one-piece design of the car seat back panel cannot be disassembled individually. When damage occurs inside the car seat requiring repair, the inconvenience of disassembling the one-piece panel complicates the repair process. Therefore, it is necessary to provide a flame-retardant and noise-absorbing back panel structure for car seats to address these issues.

[0005] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Summary of the Invention

[0024] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0025] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0026] like Figures 1-2 As shown, this application provides a flame-retardant and noise-absorbing back panel structure for automotive seats, including a frame 1 and a main board 3 located within the frame 1. The frame 1 and the main board 3 constitute the automotive seat back panel structure. The frame 1 is an integral design, which ensures the stability of the outer frame of the automotive seat back panel.

[0027] The main body 3 includes a backrest 31, which is the main structure of the main body 3. When a passenger is riding in the car, the backrest 31 contacts the back of the passenger and provides support for the back of the passenger. Multiple protrusions 32 are provided on both sides of the backrest 31. One side of the protrusion 32 is away from the backrest 31. When a passenger is riding in the car, the protrusions 32 can provide support for both sides of the back of the passenger, making the car seat more comfortable.

[0028] Upper connecting rods 33 are fixedly installed on both sides of the top of the backing plate 31, and upper mounting holes 11 corresponding to the upper connecting rods 33 are opened on both sides of the frame 1. Figures 2-5 As shown, the top of the upper connecting rod 33 is provided with a first section 331 and a second section 332. The first section 331 is vertically arranged, the second section 332 is horizontally arranged, and an arc-shaped section is integrally arranged between them. The part below the second section 332 is vertically arranged.

[0029] When connecting the backing plate 31 to the frame 1, the backing plate 31 should first be placed horizontally, and the first segment 331 should be aligned with and inserted into the upper mounting hole 11. After the first segment 331 is fully inserted into the upper mounting hole 11, the arc-shaped segment is located at the upper mounting hole 11. Then, the backing plate 31 is rotated to a vertical position, and then the backing plate 31 is pushed towards the position of the upper mounting hole 11 until the arc-shaped segment enters the upper mounting hole 11. At this time, even if the backing plate 31 is subjected to external force, due to the restriction of the first segment 331, the upper connecting rod... 33 will not separate from the upper mounting hole 11. The first section 331 and the second section 332 on the upper connecting rod 33 provide a preliminary connection between the back plate 31 and the frame 1. At the same time, a soft buckle 12 is provided outside the upper mounting hole 11. The soft buckle 12 is fixedly connected to the frame 1. After the upper connecting rod 33 is connected to the upper mounting hole 11, the second section 332 is located inside the soft buckle 12. There is a certain friction between them. The soft buckle 12 prevents the upper connecting rod 33 from automatically sliding down under the action of gravity.

[0030] Side pins 13 are fixedly installed on both sides of the frame 1. The side pins 13 are located in the middle of the frame 1. At the same time, a side connecting rod 34 is fixedly installed on the side away from the bottom of the upper connecting rod 33. Side holes are provided on both sides of the side connecting rod 34. When the backing plate 31 is installed, one end of the side pin 13 is inserted into the side hole. The side hole limits the vertical and horizontal directions of the side pin 13, further stabilizing the connection between the backing plate 31 and the frame 1.

[0031] Continue to refer to Figures 2-5Both sides of the bottom of the frame 1 are provided with screw holes 14, and both sides of the bottom of the back plate 31 are fixedly installed with connecting plates 35. The connecting plates 35 are threaded with connecting bolts 36. The connecting bolts 36 lock the connecting plates 35 and the screw holes 14 through the threads, thereby fixing the bottom of the back plate 31 to the frame 1, making the connection between the back plate 31 and the frame 1 more stable.

[0032] The backing plate 31 is fixed to the frame 1 at three positions from top to bottom. The installation sequence is also from top to bottom. When disassembling, simply unscrew the bottom connecting bolt 36 first, and then separate the backing plate 31 from the frame 1.

[0033] In this application, the main body 3 and the frame 1 are made of polypropylene as the matrix, reinforced with long glass fibers, and compounded with phosphorus and nitrogen-based halogen-free intumescent flame retardants and nano flame retardants. During use, the phosphorus and nitrogen-based halogen-free intumescent flame retardants and nano flame retardants play a flame-retardant role, avoiding the risk of fire in the car seat. Secondly, polypropylene plays a role in absorbing dryness. When the passenger leans against the back panel for a long time and gets hot and sweaty, polypropylene can absorb dryness and increase the passenger's comfort. Finally, the long glass fibers provide toughness to the car seat back panel, which is suitable for bending while meeting the load-bearing requirements of the back panel.

[0034] Continue to refer to Figure 2 A base 2 is hinged to the bottom of the frame 1. The frame 1, the main body 3, and the base 2 constitute the car seat frame. The backrest 31 is inclined from top to bottom along the direction close to the front side of the base 2. This setting makes the curve of the backrest 31 increase the comfort of the human body when sitting. In addition, a recessed part 37 is provided in the middle of the backrest 31. The recessed part 37 can support the waist of the passenger, making the design of the car backrest more perfect.

[0035] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
