Description

Technical Field

[0001] This utility model relates to the field of automotive seat technology, and in particular to an automotive seat back assembly with side wings. Background Technology

[0002] In the design and manufacturing of modern automotive seats, the comfort, support, and functionality of seat back structures have always been crucial considerations. As consumers' demands for seat experience continue to rise, the design of seat back structures is constantly being innovated and optimized. Within the seat back structure, the side wings play a key role in providing lateral support to the body and enhancing the feeling of being enveloped while seated.

[0003] Traditional side-bolt designs for chair backs have many limitations. For example... Figure 1 As shown, traditional side-wing support steel wires 5 typically employ a two-part independent structure, corresponding to the side wings on both sides of the backrest. This independently designed traditional side-wing support steel wire 5 needs to be fixed to the backrest frame by welding before being embedded in the backrest foam. However, this traditional design has revealed a series of problems in practical applications. When the backrest foam collapses to a certain extent under human pressure, the traditional side-wing support steel wire 5 easily causes a noticeable foreign body sensation for the user. This is because during the deformation of the backrest foam under stress, the relative position between the steel wire and the human body changes, and the hard surface of the steel wire directly contacts the body, destroying the original soft and comfortable feel of the seat backrest and reducing seating comfort. Utility Model Content

[0004] In view of the problems existing in the prior art, the present invention aims to provide a car seat back assembly with side wings to solve the problem that the traditional side wing brace steel wire structure can easily cause users to feel a significant foreign object.

[0005] To achieve the above objectives, this utility model provides a car seat back assembly with side wings, including a backrest foam with side wings at both ends and side wing support steel wires. The side wing support steel wires are joined end to end to form a rectangular structure, which is integrally foamed inside the backrest foam. The side wing support steel wires extend vertically, and their two ends correspond to the positions of the two side wings of the backrest foam, and the two ends are arched forward to support the side wings of the backrest foam.

[0006] The above solution also includes a fan and an air bag. The air bag has a fan connection port on its back. A plastic plate is embedded inside the air bag corresponding to the fan connection port. The plastic plate has mounting holes communicating with the fan connection port. The fan is snapped into the mounting holes via an inverted clip structure, thus fixing it to the plastic plate and subsequently to the back of the air bag. After sealing both ends of the air bag, it extends outwards to form fixing lugs. Steel wires are pre-embedded within the foam backrest at the positions corresponding to the fixing lugs. The fixing lugs are fixed to the corresponding steel wires using C-shaped nails. Traditional backrest fans are usually fixed to the backrest frame using sheet metal parts. This structure eliminates the sheet metal parts required in traditional installation methods, using only low-cost materials such as C-shaped nails, effectively reducing material costs and simplifying the installation process.

[0007] In the above solution: the left and right ends of the air bag extend outward to form two fixed ears with vertical spacing. The fixed ears are provided with nail holes. By fixing at multiple points, the air bag is more firmly fixed on the backrest foam, reducing the possibility of shaking and displacement, and ensuring the overall stability of the fan and air bag system.

[0008] In the above scheme: a fixing steel wire is pre-embedded in each fixing lug corresponding to the backrest foam. The fixing steel wire is a rectangular steel wire joined end to end, and the two fixing lugs at both ends are fixed to the left and right ends of the fixing steel wire with C-shaped nails. The joined rectangular steel wires form a closed loop structure. This structure has high strength and rigidity. When the air bag is subjected to external force, the fixing steel wire can effectively bear and transmit these forces, distributing the local force to the entire steel wire loop, thereby improving the load-bearing capacity of the entire backrest fan installation structure. The fixing steel wire also has a certain supporting effect on the backrest foam.

[0009] In the above solution, the plastic plate is pasted or sewn onto the inner wall of the back of the air bag, which has a simple structure and is easy to install.

[0010] In the above scheme: the side wing support steel wire is formed by splicing two steel wires together and welding them together. The side wing support steel wire is formed as a single piece, which may require complex molds and forming processes, increasing production difficulty and cost. Using two spliced ​​steel wires allows for simple forming of each wire separately, simplifying the overall process.

[0011] The beneficial effects of this utility model are:

[0012] 1. The interlocking design of the side wing support wires ensures a tight bond between the wires and the backrest foam, resulting in a stable overall structure. Furthermore, the vertically extending wires with forward-arching ends precisely align with the sides of the backrest foam, effectively supporting the wings and ensuring they maintain their shape for comfortable lateral support. 2. Because the side wing support wires are integrally foamed within the backrest foam, they float with the foam when it collapses under pressure from the body, effectively preventing any feeling of foreign objects in the backrest.

[0017] Figure 5 This is an assembly diagram of the air bag and the foam backrest. Detailed Implementation

[0018] like Figure 2 As shown in Figure 5, a car seat backrest assembly with side wings mainly consists of backrest foam 3 with side wings at both ends and side wing support steel wire 6.

[0019] The side wing support steel wires 6 are joined end to end to form a rectangular structure, which is integrally foamed inside the backrest foam 3. The side wing support steel wires 6 extend vertically, and their two ends correspond to the positions of the two side wings of the backrest foam 3. The two ends are arched forward to achieve the support shape for the side wings of the backrest foam 3.

[0020] Ideally, it also includes a fan 1 and an air bag 2. The back of the air bag 2 has a fan connection port. Inside the air bag 2, corresponding to the fan connection port, a plastic plate is built-in and fixed. The plastic plate has mounting holes communicating with the fan connection port. The fan 1 is snapped into the mounting holes via an inverted clip structure, thus fixing it to the plastic plate and subsequently to the back of the air bag 2. After sealing both ends of the air bag 2, it extends outwards to form fixing lugs 4. Steel wires are pre-embedded inside the backrest foam 3 at the positions corresponding to the fixing lugs 4. The fixing lugs 4 are fixed to the corresponding steel wires using C-shaped nails. Traditional backrest fans are usually fixed to the backrest frame using sheet metal parts. This structure eliminates the sheet metal parts required in traditional installation methods, using only low-cost materials such as C-shaped nails, effectively reducing material costs and simplifying the installation process.

[0021] Ideally, the air bag 2 extends outward at both ends to form two fixed supports 4 with vertical spacing. The fixed supports 4 are provided with nail holes. By fixing at multiple points, the air bag 2 is more firmly fixed on the backrest foam 3, reducing the possibility of shaking and displacement, and ensuring the overall stability of the fan 1 and air bag 2 system.

[0022] Ideally, a fixing wire should be pre-embedded within the backrest foam 3, corresponding to each fixing lug 4. This fixing wire is a rectangular wire joined end-to-end, with the fixing lugs 4 at both ends secured to the left and right ends of the fixing wire using C-shaped nails. The joined rectangular wires form a closed-loop structure, which possesses high strength and rigidity. When the air bag 2 is subjected to external force, the fixing wire can effectively bear and transmit these forces, distributing the localized stress across the entire wire loop. This improves the load-bearing capacity of the entire backrest fan installation structure, and the fixing wire also provides some support to the backrest foam 3.

[0023] Ideally, the plastic sheet should be glued or sewn onto the inner back wall of the air bag 2, which is simple in structure and easy to install.

[0024] Specifically, the air bag 2 includes a top part 21 and a main body part 22 that are connected to each other. The fan 1 is fixed on the top part 21 of the air bag 2, and the fixing lugs 4 are located at both ends of the top part 21. The main body part 22 of the air bag 2 is fixed to the backrest frame by screws.

[0025] Ideally, the side-bracing steel wire 6 is formed by splicing two steel wires together and welding them together. Molding the side-bracing steel wire 6 as a single piece might require complex molds and forming processes, increasing production difficulty and cost. Using two spliced ​​steel wires allows for simpler forming of each wire separately, simplifying the overall process.
