Description

Technical Field

[0001] This utility model relates to the field of automotive seats, and in particular to a simplified support structure for a seat back. Background Technology

[0002] With the continuous development of industrial technology, the demand for lightweight, high-strength, and highly durable structures is increasing in the automotive manufacturing field. Traditional seat backrests rely on a serpentine spring in the middle of the backrest frame for support, such as... Figure 1 As shown, serpentine springs have a certain degree of elasticity and support, but they are expensive and require additional hooks for installation, increasing design time and difficulty. In most cases, felt is also needed to prevent abnormal noise. Utility Model Content

[0003] In view of this, the purpose of this utility model is to provide a simplified support structure for a seat back, which simplifies the structure, reduces weight and investment costs, and ensures sufficient load-bearing capacity and resistance to deformation.

[0004] This utility model is achieved by the following solution: a simplified support structure for a seat back, including a backrest frame, wherein a back frame rib is provided in the middle of the backrest frame, the back frame rib is concave, and the two ends of the back frame rib are welded to the side plates on both sides of the backrest frame.

[0005] Furthermore, the back frame rib includes a horizontal section in the middle, inclined sections that bend upwards at both ends of the horizontal section, and a vertical section that bends upwards to a vertical angle at the upper end of the inclined section. The vertical sections at both ends of the back frame rib are welded to the side plates on both sides of the backrest frame.

[0006] Furthermore, the back frame ribs are made of spring steel.

[0007] Compared with the prior art, the present invention has the following advantages: The simplified support structure of the seat back of the present invention is reasonably designed. Under the premise of ensuring sufficient load-bearing capacity and anti-deformation capacity, it greatly simplifies the structure, reduces manufacturing and design difficulty, and reduces weight and investment costs.

[0008] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below through specific embodiments and related drawings. Attached Figure Description

[0015] It should be noted that the following detailed descriptions are exemplary and intended to provide further explanation of this application. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0016] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0017] like Figures 2-5 As shown, a simplified support structure for a seat back includes a backrest frame 100, with a concave backrest rib 200 in the middle of the backrest frame. The two ends of the backrest rib are welded to the side plates 110 on both sides of the backrest frame 200. This simplified seat back support structure significantly simplifies the structure, reduces manufacturing and design difficulty, and lowers weight and investment costs while ensuring sufficient load-bearing capacity and deformation resistance. The concave backrest rib also provides a spring-like effect.

[0018] In this embodiment, the back frame rib 200 includes a horizontal section 210 in the middle, inclined sections 220 that bend upwards at both ends of the horizontal section, and a vertical section 230 that bends upwards to a vertical angle at the upper end of the inclined section. The vertical sections at both ends of the back frame rib are welded to the side plates on both sides of the backrest frame.

[0019] In this embodiment, the length of the horizontal section of the back frame rib is 15~20cm, the length of the inclined section is 18~25cm, the included angle between the horizontal section and the inclined section is 120°~150°, and the length of the vertical section is 3~5cm.

[0020] In this embodiment, the back frame ribs are made of spring steel, and the diameter of the back frame ribs is 0.5~0.8cm.

[0021] One backrest rib can basically replace three spring structures. When sitting in the seat, the backrest leans back and the seat cushion is compressed backward. The backrest rib supports the cushion and slowly deforms backward elastically, avoiding the feeling of the back not being able to support the body. When not leaning back, the backrest rib can also elastically return to its original position, which also has the effect of a spring.

[0022] Unless otherwise stated, if any of the technical solutions disclosed in this utility model discloses a numerical range, then the disclosed numerical range is a preferred numerical range. Any person skilled in the art should understand that the preferred numerical range is merely one among many feasible numerical values ​​that has a more obvious or representative technical effect. Because there are many numerical values, it is impossible to list them all. Therefore, this utility model discloses only some numerical values ​​to illustrate the technical solutions of this utility model. Furthermore, the numerical values ​​listed above should not constitute a limitation on the scope of protection of this utility model.

[0023] If this utility model discloses or relates to mutually fixedly connected parts or structural components, then unless otherwise stated, a fixed connection can be understood as: a detachable fixed connection (e.g., using bolts or screws), or a non-detachable fixed connection (e.g., riveting, welding). Of course, mutually fixed connections can also be replaced by an integral structure (e.g., manufactured by integral molding using a casting process) (except where it is obviously impossible to use an integral molding process).

[0024] In addition, unless otherwise stated, the terms used to indicate positional relationships or shapes in any of the technical solutions disclosed in this utility model above include states or shapes that are similar to, close to, or approximate with them.

[0025] Any component provided by this utility model can be assembled from multiple individual components, or it can be a single component manufactured by a one-piece molding process.

[0026] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
