Description

Technical Field

[0001] The present invention relates to the technical field of cushion products, and more specifically, to a TPU composite fabric cushion.

Background Art

[0002] As a common household item, cushions are widely used in various scenes such as homes, offices, vehicles, and travel. They mainly provide support for the human body and comfortable cushioning, relieve local pressure, soothe fatigue, and improve sitting comfort. Existing cushions are rich in variety and diverse in structural forms, usually composed of an outer fabric and an inner filling. Structurally, they can be roughly classified into three categories: general cotton-filled cushions, sponge / foam cushions, and memory foam low-rebound cushions.

[0003] General cotton cushions usually use materials such as polyester fiber cotton, PP cotton, and foam cotton as fillers. These materials are low in cost and easy to fill, but their structures are loose, their compression resilience is poor, they sag and deform after long-term use, and they cannot continuously provide effective support. Sponge cushions have a certain degree of elasticity, but their recovery speed is fast, they lack a sense of fit, and they are prone to aging and cracking. On the other hand, cushion products with memory foam (low-rebound polyurethane foam) as the core have excellent rebound performance, slowly release pressure, and maintain the support effect. However, these materials are expensive, the processing and molding are complex, the air permeability is poor, they are prone to moisture absorption, and they are prone to yellowing and aging, making it difficult to maintain a good use state for a long time.

[0004] In actual applications, users are paying increasing attention not only to the softness and comfort of cushions but also to their rebound performance, fit, cost, environmental performance, and long-term durability. However, many of the existing solutions in the market are high in cost in terms of materials and construction methods, making it difficult to balance comfort and economy. In particular, it is difficult to achieve the unity of low cost and high performance in the mid- to low-price market.

[0005] On the one hand, the development of functional materials in recent years has brought new possibilities to the innovation of cushion structures. Among them, thermoplastic polyurethane elastomer (TPU) has excellent stretchability, resilience performance, wear resistance and aging resistance, so it is gradually widely used in fields such as shoe materials, bags, and medical devices. However, its application to cushion structures is still limited. Especially in the field of fabric composites, TPU materials are compounded with fabrics by methods such as thermocompression bonding to form composite fabrics that combine softness and support force, providing a new idea to break through the limitation of "the filling material determines the performance" in the conventional cushion structure.

[0006] Currently, there is still no cushion product with a simple structure, controllable cost, mature manufacturing process, and realizing cushioning and resilience performance on the premise of using general filling materials. Therefore, it is urgent to provide a new type of cushion structure. By means of material composite methods, it can give the whole cushion a support performance similar to that of memory foam, achieve both functionality and economy without relying on high-cost foaming materials, and meet the actual usage needs of various scenarios.

Modes for Carrying Out the Invention

[0020] Hereinafter, based on the drawings related to the embodiments of the present invention, the technical means in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, other embodiments that can be obtained by those of ordinary skill in the art without creative labor are all included in the protection scope of the present invention. Embodiment

[0021] As shown in Figures 1 to 3, the TPU composite fabric cushion provided by the present invention has a simple structure and excellent support and resilience performance. The following will specifically describe this cushion body with reference to the drawings.

[0022] The cushion body is mainly composed of the following components: an outer cloth layer 1, a TPU composite layer 2, and an internal filling layer 3.

[0023] The three-layer structure is laminated to form the main components of the cushion body.

[0024] As shown in Figure 1, the cushion body has an overall pillow-like structure, is soft and compressible, and is applicable to various support usage scenarios. Its outermost layer is the external fabric layer 1, which provides the surface that directly contacts the user; a layer of TPU composite layer 2 is closely attached to its inner side, and this layer provides excellent elastic deformation and restoration capabilities; the innermost layer is the filling layer 3, which provides shape support and a soft touch.

[0025] The external fabric layer 1 and the TPU composite layer 2 are bonded together to form an integral composite fabric structure, and through edge sealing or stitching, a closed housing structure is formed. The filling layer 3 is installed inside this housing to constitute a complete cushion body.

[0026] The external fabric layer 1 is made of a flexible fiber fabric material, such as polyester-cotton fabric, linen-like fabric, velvet fabric, etc., and has excellent air permeability, touch, and appearance decorativeness. This fabric constitutes the outer surface of the cushion body, directly contacts the user, and provides a soft and comfortable usage experience.

[0027] The TPU composite layer 2 is a thermoplastic polyurethane elastic sheet material, which is bonded to the external fabric layer 1 by a thermal compression bonding method or a laminating method. This layer has a high elastic modulus, causes controllable deformation during use, and quickly restores to its original shape, thereby providing a rebound support effect similar to that of a memory foam to the cushion body.

[0028] The filling layer 3 is filled into the housing structure composed of the external fabric layer 1 and the TPU composite layer 2, and conventional soft filling materials, such as polyester fiber cotton, PP cotton, sponge crushed material, etc., are selected. The filling layer 3 mainly provides the three-dimensional shape and basic support feeling of the cushion body, and with the assistance of the TPU composite layer 2, an excellent buffering and rebound experience can be obtained.

[0029] The manufacturing procedure of the cushion body of this utility model is as follows: Select a soft fabric, cut it to a predetermined size to form the external fabric layer 1; Cut the TPU elastic membrane material to the size matched with the fabric to form the TPU composite layer 2; Fix the TPU composite layer 2 inside the outer fabric layer 1 by means of hot pressing or lamination method; Sew or heat-weld the two composite structures to form a bag body, leaving a filling opening; Fill the filling layer 3 inside the bag body; Seal the filling opening and complete the overall assembly of the cushion body.

[0030] During use, the filling layer 3 of the cushion body is compressed by the pressure of the human body, and at the same time, the TPU composite layer 2 deforms with the compression. When the pressure is released, the TPU composite layer 2 quickly restores to its original shape, pulling the rebound of the filling layer 3 and presenting an overall comfortable "low-rebound" characteristic.

[0031] With this structure, the cushion body realizes a buffer support effect similar to that of memory foam despite using conventional filling materials, significantly improving comfort and service durability.

[0032] The cushion body can be applied to the following various scenes: Office scene: Used as a lumbar support or a backrest; Vehicle scene: Used for neck pillows, backrests, seat cushions, etc.; Home scene: Used as a sofa cushion, a bed head pillow, or a children's nap pillow; Travel scene: Manufactured into a U-shaped neck pillow, a foldable head pad, etc. Also, the structure of the cushion body can be modified as follows: Shape adjustment: It can be made into a rectangle, a square, a U-shape, or a lumbar support shape; Function integration: A heating film, an aroma pack, magnetic sheets, etc. can be provided inside; Surface improvement: A zipper or a detachable cover can be provided on the outer fabric layer 1.

[0033] From the above description of the disclosed embodiments of the present invention, those skilled in the art can implement or use the present invention. Many modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown in the text, but follows the broadest scope consistent with the principles and novel features disclosed in the text.
