Description

Technical Field

[0001] This utility model relates to the field of automotive seat technology, and in particular to a customizable automotive seat backrest. Background Technology

[0002] In today's society, with the significant improvement in people's living standards, consumers' demands for the comfort and personalization of car seats are also increasing. As an important part of the car interior, the design of the seat back directly affects the riding experience of the driver and passengers. Especially during long-distance travel or daily commutes, an ergonomic seat back that can provide good lumbar support is particularly important.

[0003] However, traditional car seat backrest designs mostly use fixed-shape lumbar support foam. While this lumbar support foam can provide basic support and comfort to a certain extent, its fixed shape makes it difficult to meet the personalized needs of different consumers. In particular, regarding lumbar support, different consumers have different body shapes, sitting habits, and lumbar curves. A fixed-shape backrest often cannot provide just the right amount of support for each user, which may lead to lower back discomfort or fatigue during long periods of sitting. Utility Model Content

[0004] In view of the problems existing in the prior art, the present invention aims to provide a customizable car seat backrest, which can be made with lumbar support foam according to the consumer's preferences and lumbar curve, and quickly assembled onto the backrest frame to provide precise lumbar support.

[0005] To achieve the above objectives, this utility model proposes a customizable car seat backrest, including a backrest frame and a lumbar support. The lumbar support includes a lumbar support frame and lumbar support foam, with the lumbar support foam covering the lumbar support frame. The lumbar support frame is detachably fixed to the backrest frame.

[0006] In the above solution: the upper ends of the lumbar support frame are provided with U-shaped forks opening upwards on both sides; the backrest frame is provided with a horizontal steel wire corresponding to the two U-shaped forks; the U-shaped forks are inserted upwards into the horizontal steel wire; and the lower end of the lumbar support frame is locked to the backrest frame with bolts. This "U-shaped fork insertion + bolt locking" fixing mechanism allows for quick assembly and disassembly of the lumbar support.

[0007] In the above solution: mounting blocks are provided on both sides of the lower end of the lumbar support frame, and threaded holes extending forward and backward are provided on the mounting blocks. Two lugs are provided on each of the two mounting blocks on the backrest frame, and through holes communicating with the threaded holes are provided on the lugs. The mounting blocks fit into the corresponding lugs, and the bolts pass through the through holes and are screwed into the threaded holes to lock the lower end of the lumbar support frame with the backrest frame. The structure is stable and the support is reliable, ensuring that the lumbar support will not shake during use.

[0008] In the above scheme: the lumbar support frame is a square frame, the U-shaped fork and the mounting block are welded to the back of the square frame, the lumbar support foam covers the front of the lumbar support frame, and the U-shaped fork and the mounting block on the lumbar support frame do not interfere with each other.

[0009] The above solution also includes a backrest foam and a backrest cover covering the backrest foam. The back of the backrest foam has a hollowed-out part corresponding to the two ear positions. The backrest cover can be opened and closed by a zipper installed on it at the position corresponding to the hollowed-out part, so as to conveniently install or remove bolts from the back of the backrest, thereby locking or disassembling the lumbar support frame and the backrest frame.

[0010] The beneficial effects of this invention are: the lumbar support foam can be manufactured according to the consumer's preferences and lumbar curve, and then quickly assembled onto the backrest frame to provide precise lumbar support. It also allows for easy addition of lumbar support features based on the consumer's needs. In short, this invention adopts a replaceable lumbar support design, allowing consumers to choose a matching seat back according to their preferences and needs, thereby enhancing the overall driving and riding experience. Attached Figure Description

[0011] The above and / or additional aspects and advantages of this utility model will become apparent and readily understood from the description of the embodiments taken in conjunction with the following drawings, in which:

[0012] Figure 1 This is a schematic diagram of the structure of this utility model.

[0013] Figure 2 This is a schematic diagram of the structure of an auricle.

[0015] Figure 4 This is a schematic diagram of the assembly of the lumbar support frame and the backrest frame. Detailed Implementation

[0016] like Figure 1 As shown in Figure 4, a customizable car seat backrest mainly consists of a backrest frame 1 and a lumbar support. The lumbar support includes a lumbar support frame 2 and a lumbar support foam 3, with the lumbar support foam 3 covering the lumbar support frame 2. The lumbar support frame 2 is detachably fixed to the backrest frame 1.

[0017] Ideally, the upper ends of the lumbar support frame 2 are equipped with U-shaped forks 4 opening upwards on both sides, and a horizontal steel wire 5 is provided on the backrest frame 1 corresponding to the two U-shaped forks 4. The U-shaped forks 4 are inserted upwards into the horizontal steel wire 5, and the lower end of the lumbar support frame 2 is locked to the backrest frame 1 with bolts. The "U-shaped fork 4 insertion + bolt locking" fixing mechanism allows for quick assembly and disassembly of the lumbar support.

[0018] Ideally, the lower end of the lumbar support frame 2 is provided with mounting blocks 6 on both sides. The mounting blocks 6 are provided with threaded holes extending forward and backward. The backrest frame 1 is provided with two lugs 7 corresponding to the two mounting blocks 6. The lugs 7 are provided with through holes communicating with the threaded holes. The mounting blocks 6 fit into the corresponding lugs 7, and the bolts pass through the through holes and are screwed into the threaded holes to lock the lower end of the lumbar support frame 2 with the backrest frame 1. The structure is stable and the support is reliable, which can ensure that the lumbar support will not shake during use.

[0019] Ideally, the lumbar support frame 2 is a square frame, with the U-shaped fork 4 and mounting block 6 welded to the back of the square frame, and the lumbar support foam 3 covering the front of the lumbar support frame 2. The U-shaped fork 4 and mounting block 6 on the lumbar support frame 2 do not interfere with each other and the lumbar support foam 3.

[0020] Ideally, it also includes a backrest foam and a backrest cover covering the backrest foam. The back of the backrest foam has cutouts corresponding to the two lugs 7. A zipper installed on the backrest cover at the corresponding cutout position allows for easy installation or removal of bolts from the back of the backrest, thereby locking or disassembling the lumbar support frame 2 from the backrest frame 1. This invention allows the lumbar support foam 3 to be manufactured according to consumer preferences and lumbar curves, and then quickly assembled onto the backrest frame 1 to provide precise lumbar support. It also facilitates the addition of lumbar support configurations according to consumer needs. After the seat back is assembled, the lumbar support can still be quickly installed and removed without interfering with the backrest foam and other components.
