Description

Technical Field

[0001] This utility model relates to the field of automotive seat air-conditioning front lean-back technology, specifically to a semi-sewn, semi-formed fabric. Background Technology

[0002] Air-conditioned forward-facing seat supports are designed for use with automotive air conditioning systems. These supports utilize external airflow more directly through the front space of the vehicle, improving the cooling and heating efficiency of the air conditioning. The non-woven fabric structure of the forward-facing supports is soft and breathable, effectively enhancing the seat's tactile feel. In conjunction with the air conditioning system, the seat surface automatically adjusts its temperature, enhancing comfort, especially during winter and summer driving, preventing the seats from becoming too cold or too hot, and improving the driving and riding experience.

[0003] To enhance comfort and fit, car seat backrests often incorporate multiple curved transitions, local concave-convex structures, and irregular contours. However, the non-woven fabric structure of air-conditioned backrests is generally based on flat fabric, which is sewn together to form an integral structure. The fabric itself lacks the ability to form three-dimensional shapes, and when covering complex shapes, it is prone to wrinkles, uneven stretching, or poor fit. It is also prone to accelerated fabric wear due to localized stress. Furthermore, due to the limitations of fabric stretchability and sewing precision, it is prone to problems such as hole misalignment, edge wrinkling, or insufficient sealing, resulting in unstable ventilation. Therefore, we proposed a semi-sewn, semi-formed fabric. Utility Model Content

[0004] To address the aforementioned issues, a semi-sewn, semi-formed fabric is provided. By clearly defining the main body of the formed fabric for curved surfaces, irregular contours, or concave and convex structures, the fit between the main body of the product and the seat foam is improved, ensuring the stability and sealing of the structure around the functional holes. This avoids poor ventilation caused by deformation of the sewn product. It also solves the technical problem that the non-woven fabric structure of the front and outer part of the air-conditioning unit is generally based on flat fabric, which lacks three-dimensional forming ability. When covering complex shaped areas, it is prone to wrinkles, uneven stretching, or poor fit, resulting in unstable ventilation.

[0005] To address the existing technical problems, this utility model provides a semi-sewn, semi-shaped fabric for use in car seats. The car seats have complex-shaped areas and flat-shaped areas. The semi-sewn, semi-shaped fabric includes a shaped fabric body and a sewn fabric body. The shaped fabric body is used to cover the complex-shaped areas of the product body. The sewn fabric body is used to cover the flat-shaped areas of the product body. The shaped fabric body and the sewn fabric body are fixedly connected to form an integrated structure.

[0006] Preferably, the main body of the molded fabric has an irregularly shaped surface that matches the complex shape of the car seat.

[0007] Preferably, the main body of the sewn fabric has a flat surface that matches the flat shape area of ​​the car seat.

[0008] Preferably, the main body of the product has functional holes, and the complex-shaped area of ​​the car seat near the functional holes is covered by the molded fabric body.

[0009] Preferably, the functional holes are designed to match the air conditioning ventilation holes of the car seat, and the main body of the shaped fabric completely covers the air conditioning ventilation holes of the car seat.

[0010] Preferably, the shaped fabric body and the sewn fabric body are fixedly connected by textile threads.

[0011] Preferably, the sewn fabric body covers all flat shaped areas on the car seat except for complex shaped areas.

[0012] The advantages of this utility model compared to the prior art are:

[0013] 1. By clearly defining the main body of the molding fabric for curved surfaces, irregular contours, or concave and convex structures, the fit between the main body of the product and the seat foam is improved, ensuring the stability and sealing of the structure around the functional holes, and avoiding poor ventilation due to deformation of the sewn products. This solves the technical problem that the non-woven fabric structure of the front and outer part of the air-conditioning type is generally based on flat fabric, which lacks three-dimensional forming ability. When covering complex shaped areas, it is easy to have wrinkles, uneven stretching, or poor fit, resulting in unstable ventilation.

[0014] 2. By limiting the use of the sewn fabric body to flat or regular geometric areas, the low-cost advantage of sewn products in flat areas is fully utilized, the production time in non-complex areas is shortened, the overall production cost is further reduced, and the production efficiency is improved. This solves the technical problems of high overall production costs caused by using fully molded fabric bodies for the main body of the product, or the increased process complexity caused by multiple processing and adjustments required for fully sewn products in complex areas.

[0021] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0022] See Figures 1-3 As shown, a semi-sewn, semi-shaped fabric is used in car seats. The car seats have complex-shaped areas and flat-shaped areas. The semi-sewn, semi-shaped fabric includes a shaped fabric body 2 and a sewn fabric body 3. The shaped fabric body 2 is used to cover the complex-shaped areas of the product body 1. The sewn fabric body 3 is used to cover the flat-shaped areas of the product body 1. The shaped fabric body 2 and the sewn fabric body 3 are fixedly connected to form an integrated structure.

[0023] Specifically, in complex shapes, such as curved surfaces, irregular structures, and the area around functional holes 4, the main body 2 of the molded fabric is used to ensure the precise molding of complex product contours and meet the needs of diverse shapes and refined structures in scenarios such as car seats; in flat or regular areas, the main body 3 of the sewn fabric is used to make full use of the low cost advantage of sewn products, reduce the overall material cost, and thus achieve a balance between ensuring accuracy in complex areas and controlling costs in flat areas.

[0024] Product body 1 can be produced directly using existing molding and sewing technologies, which lowers the production threshold and equipment investment costs, facilitating rapid mass production. The combination of the molded fabric body 2 and the sewn fabric body 3 ensures the structural stability and sealing of core areas such as functional holes 4, while the efficient coverage of the sewn fabric body 3 simplifies the production process for non-critical areas. This enhances the fit and durability of product body 1, while also improving its adaptability to diverse needs, providing a feasible path for functional upgrades and cost control in products such as automotive seats.

[0025] See Figure 1 and Figures 3-4 As shown, the main body 2 of the molded fabric has an irregularly shaped surface that matches the complex shape of the car seat.

[0026] Specifically, by clearly defining the application scenarios of the main body 2 of the molding fabric for curved surfaces, irregular contours, or concave and convex structures, the complex areas that require high-precision molding are precisely identified, effectively avoiding the problem of shape distortion caused by improper material selection, improving the fit between the main body 1 of the product and the seat foam, and ensuring the stability and consistency of complex shapes.

[0027] See Figure 2 and Figure 5 As shown, the sewn fabric body 3 has a flat surface that matches the flat shape area of ​​the car seat.

[0028] Specifically, the sewn fabric body 3 is limited to flat or regular geometric areas, which fully leverages the low-cost advantage of sewn products in flat areas, while simplifying the operation of the sewing process, shortening the production time in non-complex areas, further reducing the overall production cost and improving production efficiency.

[0029] See Figures 1-4 As shown, the molded fabric body 2 has functional holes 4, and the complex-shaped area of ​​the car seat near the functional holes 4 is covered by the molded fabric body 2.

[0030] Specifically, the complex area around the functional hole 4 is designated to be covered by the main body 2 of the molded fabric to ensure the stability and sealing of the structure around the functional hole 4, avoid the failure of the functional hole 4 due to the deformation of the sewn product, prevent poor ventilation, and ensure the reliability of the core function.

[0031] See Figures 1-4 As shown, the functional hole 4 is used to cooperate with the opening of the air conditioning ventilation hole of the car seat, and the main body of the molded fabric 2 completely covers the air conditioning ventilation hole of the car seat.

[0032] Specifically, for air conditioning ventilation holes, the main body 2 of the molded fabric completely covers the area, which can accurately adapt to the size and outline of the air conditioning hole, ensuring that the ventilation performance is not affected by the splicing of materials, while improving the structural strength around the air conditioning hole and extending the service life of the product.

[0033] See Figure 1 As shown, the shaped fabric body 2 and the sewn fabric body 3 are fixedly connected by sewing with textile thread.

[0034] Specifically, the forming fabric body 2 and the sewn fabric body 3 are connected by sewing. The forming fabric body 2 and the sewn fabric body 3 can be stably combined without additional equipment. Production can be completed using existing sewing technology, reducing equipment investment costs. Moreover, the sewing connection has high strength and is not easy to fall off.

[0035] See Figure 2 and Figure 5 As shown, the sewn fabric body 3 covers all flat shaped areas on the car seat except for complex shaped areas.

[0036] Specifically, the sewing fabric body 3 is limited to cover all flat areas, maximizing the application range of the sewing fabric body 3, further reducing the overall material cost, and reducing the amount of molded fabric body 2 used. Under the premise of ensuring functionality, the cost is optimized. The molded fabric body 2 corresponds to the air conditioning vent position of the car seat, and the sewing fabric body 3 covers the remaining flat surface of the front of the seat.

[0037] For the specific scenario of forward-leaning car seats, the coverage positions of the molded fabric body 2 and the sewn fabric body 3 are clearly defined, so that the structural design is highly matched with the actual needs of the product. This ensures the function of the air conditioning vents and simplifies production by covering the remaining flat surfaces with the sewn fabric body 3, thereby improving the adaptability of the product for mass production.

[0038] Working Principle: By precisely dividing the application areas of the molding fabric body 2 and the sewn fabric body 3, the synergistic optimization of function, cost, and production efficiency is achieved: The molding fabric body 2 clearly covers complex shapes such as curved surfaces and irregular contours, as well as the area around functional holes 4 such as air conditioning ventilation holes, ensuring the molding accuracy of complex structures, the stability and ventilation performance of functional holes 4, and improving the fit and service life of the product with the seat foam; The sewn fabric body 3 is limited to covering flat or regular geometric areas, maximizing its low-cost advantage, simplifying the sewing process to improve efficiency, and reducing production time and cost in non-complex areas; The two are connected by sewing, and a stable combination can be achieved using existing processes, reducing equipment investment. At the same time, the coverage position is clearly defined for the car seat forward-leaning scenario, so that the structural design is highly matched with actual needs, achieving optimal cost while ensuring functionality, and improving the adaptability for mass production.

[0039] The above embodiments only illustrate one or more implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
