Description

Technical Field

[0001] This utility model relates to the field of automotive seat technology, and in particular to a cover structure for the stepped area of ​​a seat cushion. Background Technology

[0002] As automotive interior design moves towards personalization and premiumization, the complexity of seat shapes has significantly increased, especially the stepped area at the front of the seat cushion, which has become a key area for differentiating seat designs. However, the stepped protrusions in traditional seat cushion foam often pose challenges for fabric upholstery. Due to the unique shape of these protrusions, traditional seat covers often fail to perfectly conform to the contours of the protrusions, resulting in complex upholstery processes. This not only affects the aesthetics of the seat, making it less personalized and failing to meet consumers' demands for unique and stylish seats, but this misfit can also lead to loosening and wrinkling of the cover during use, impacting the seat's comfort and durability. Utility Model Content

[0003] In view of the problems existing in the prior art, the present invention aims to provide a cover covering structure for the step area of ​​the seat cushion, which can achieve a tight fit between the seat cushion cover and the raised part of the step.

[0004] To achieve the above objectives, this utility model proposes a seat cushion step area cover structure, including a seat cushion frame, a seat cushion foam, and a seat cushion cover. The seat cushion foam includes a foam body and a step protrusion designed at the front end of the foam body. The parting line between the front end of the step protrusion and the foam body is designed in a hollow shape to form a through-hole. Two horizontal steel wires are fixedly installed on the seat cushion frame at the position below the through-hole. The two horizontal steel wires are arranged at intervals. The seat cushion cover includes a first cover and a second cover. After the first cover covers the step protrusion, its end passes through the through-hole and is fixed to one of the horizontal steel wires. The first end of the second cover is sewn onto the first cover near the through-hole. The second cover covers the front end area of ​​the foam body, and its end goes around the bottom edge of the front end of the foam body and is then fixed to the other horizontal steel wire.

[0005] In the above scheme: both the first and second face covers are made by sewing together multiple face cover pieces, which is convenient to process.

[0006] In the above solution: the top and front surfaces of the front end area of ​​the foam body are provided with at least two recessed grooves for placing the backrest cover splice joints, and the recessed grooves are spaced apart on the left and right. The design of the recessed grooves allows the splice joints of the backrest cover to be hidden within them, avoiding the splice joints protruding and forming obvious and abrupt marks on the surface of the cushion. This makes the cushion appearance more flat and smooth, giving people a simple and exquisite feeling from a visual perspective.

[0007] In the above solution: two C-shaped sheet metals are arranged on the left and right sides of the seat cushion frame. The horizontal steel wires are welded and fixed to the two C-shaped sheet metals. The two ends of the two horizontal steel wires extend backward and then upward to form legs. The two legs of one horizontal steel wire are fixed to the seat cushion frame, and the two legs of the other horizontal steel wire are welded and fixed to the two legs of the previous horizontal steel wire, ensuring the installation stability of the horizontal steel wires. This fixing structure greatly enhances the installation firmness of the horizontal steel wires on the seat cushion frame, effectively resists various external forces, and avoids the steel wires from loosening, shaking, or even falling off during long-term use.

[0008] In the above scheme: the two legs of the C-shaped sheet metal and the transverse steel wire are fixed to the seat frame with screws. The pre-installation position of the screws on the two legs needs to be designed as a flat structure to facilitate the installation of the screws.

[0009] In the above solution: the end of the first face cover is fixed to the horizontal steel wire located at the rear by a hook, and the end of the second face cover is fixed to the horizontal steel wire located at the front by a hook. This design of fixing the ends of the first and second face covers to the horizontal steel wire by hooks makes it easy to assemble and disassemble the face covers.

[0010] The beneficial effects of this utility model are:

[0011] 1. The parting line between the raised step and the foam body is designed with a hollowed-out pattern, forming a perforated seam. The first cover covers the raised step and its end passes through the perforated seam for fixation. The first end of the second cover is sewn to the first cover near the perforated seam and covers the front area of ​​the foam body. This design allows the cover to fit the raised step and front areas of the seat cushion more closely and smoothly, better showcasing the seat cushion's appearance and enhancing its aesthetics. It also avoids wrinkles and bulges caused by uneven cover coverage, which can affect riding comfort. 2. This design simplifies the installation process of the cover covering the raised step area, reduces installation difficulty, and improves installation efficiency. Furthermore, because the end of the cover can flexibly bypass the bottom edge of the front of the foam body before being fixed, it further enhances the flexibility and adaptability of installation. Attached Figure Description

[0012] 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:

[0013] Figure 1 This is a schematic diagram of the seat cushion frame.

[0014] Figure 2 yes Figure 1 A bottom view.

[0015] Figure 3This is a schematic diagram of the foam structure of the seat cushion.

[0016] Figure 4 This is a schematic diagram of the first and second faceplates. Detailed Implementation

[0017] like Figure 1 As shown in Figure 4, a seat cushion step area cover structure is mainly composed of a seat cushion frame 1, a seat cushion foam, and a seat cushion cover.

[0018] The seat cushion foam includes a foam body 2 and a stepped protrusion 3 designed at the front end of the foam body 2. The parting line between the front end of the stepped protrusion 3 and the foam body 2 is designed in a hollow shape to form a through-hole 4. Two horizontal steel wires 5 are fixedly installed on the seat cushion frame 1 at the position corresponding to the lower part of the through-hole 4, and the two horizontal steel wires 5 are arranged at intervals.

[0019] The seat cover includes a first cover 6 and a second cover 7. After the first cover 6 covers the stepped protrusion 3, its end passes through the slit 4 and is fixed to one of the transverse steel wires 5. The first end of the second cover 7 is sewn onto the first cover 6 near the slit. The second cover 7 covers the front end area of ​​the foam body 2, and its end goes around the bottom edge of the front end of the foam body 2 and is fixed to another transverse steel wire 5.

[0020] Ideally, both the first cover 6 and the second cover 7 should be made of multiple cover pieces sewn together, which is convenient for processing.

[0021] Ideally, the top and front surfaces of the front end area of ​​the foam body 2 should each have at least two recessed grooves 8 for placing the backrest cover splice joint, with the recessed grooves 8 spaced apart on the left and right. The design of the recessed grooves 8 allows the splice joint of the backrest cover to be hidden within them, avoiding the splice joint protruding and forming obvious and abrupt marks on the surface of the cushion. This makes the cushion appearance flatter and smoother, giving a simple and refined visual impression.

[0022] Ideally, two C-shaped sheet metal pieces 9 are spaced apart on the left and right sides of the seat cushion frame 1. The transverse steel wires 5 are welded and fixed to the two C-shaped sheet metal pieces 9. The two ends of the two transverse steel wires 5 extend backward and then upward to form legs. The two legs of one transverse steel wire 5 are fixed to the seat cushion frame 1, and the two legs of the other transverse steel wire 5 are welded and fixed to the two legs of the previous transverse steel wire 5 respectively. This ensures the installation stability of the transverse steel wires 5. This fixing structure greatly enhances the installation firmness of the transverse steel wires 5 on the seat cushion frame 1, effectively resists various external forces, and prevents the steel wires from loosening, shaking, or even falling off during long-term use.

[0023] Ideally, both legs of the C-shaped sheet metal 9 and the transverse steel wire 5 should be fixed to the seat frame 1 with screws. The pre-installation position of the screws on the two legs should be designed as a flat structure to facilitate the installation of the screws.

[0024] Ideally, the end of the first cover 6 is hooked and fixed to the horizontal steel wire 5 located at the rear, and the end of the second cover 7 is hooked and fixed to the horizontal steel wire 5 located at the front. This design of using hooks to fix the ends of the first and second covers to the horizontal steel wire 5 makes it easy to assemble and disassemble the covers.
