Description

Technical Field

[0001] This application discloses a seamless, one-piece, traceless face mask for car seats, relating to the field of automotive supplies technology. Background Technology

[0002] Traditional car seat covers require sewing to form a single unit. This process is labor-intensive, and the stitching affects the aesthetics and comfort of the car's interior. Furthermore, the seams are prone to cracking and breaking, impacting the seat's continued use. Existing technologies, such as Chinese patent CN106393544A, entitled "A Seamless Integrated Foam Cover Structure, Preparation Mold, and Preparation Method," provide a seamless integrated foam cover structure. However, this patented solution still requires splicing between adjacent cover panels, resulting in a single structure formed by piecing together multiple panels. The surface of the overall cover still shows seam marks, affecting aesthetics. Moreover, because it uses an integrated foaming process, each cover panel is wrapped around the entire foam body. If a section of the cover is damaged, it cannot be replaced individually; the entire foam body must be replaced, leading to significant waste. Therefore, there is an urgent need in this technical field for a seamless, one-piece car seat with a replaceable, seamless surface. Utility Model Content

[0033] Example 1

[0034] This embodiment provides a seamless, one-piece, non-seamless car seat cover. (See also...) Figure 1 The car seat includes an inner frame 100 and a filling block 200 connected to the inner frame 100.

[0035] The inner skeleton 100 and the filling block 200 adopt conventional technologies, such as the inner skeleton 100 adopting a metal frame, alloy frame, carbon fiber frame or hybrid material frame, etc.

[0036] The filler block 200 adopts a partitioned structure, with different performance filler blocks 200 used for different positions and areas of the car seat. For example, the filler block 200 can be made of foam, with a structure consisting of a substrate and foam attached to the substrate. The foam can be referenced in the prior art, such as Chinese Patent CN106393544A.

[0037] In a further implementation, see Figure 2 The filler block 200 includes a substrate 201 and a foam 202 attached to the substrate 201, such as a sponge. The substrate 201 is a plastic sheet, and has connection structures such as snap-fits, threaded openings, or molding strips on it to facilitate connection and disassembly, allowing the substrate 201 to be detachably connected to the inner frame 100 for easy replacement. See [reference needed]. Figure 3 The inner frame 100 is provided with a connection structure that matches the base plate 201, such as a snap-fit ​​groove 101. Furthermore, different filling blocks are used for different positions and areas of the car seat, so that different areas have different elasticity, hardness, or density, providing different support and rebound effects in different positions and areas of the car seat.

[0038] The seamless, one-piece, seamless car seat cover provided in this application has a seamless, one-piece, seamless cover covering the inner frame and the filling block. The seamless, one-piece, seamless cover is integrally molded and structurally has at least a base layer 301 and a surface layer 302. See [link to previous document]. Figure 4 Of course, other layers, such as a buffer layer, can also be set between the base layer 301 and the surface layer 302 to improve the contact comfort of the surface layer, or an adhesive layer can be set between the base layer and the surface layer to improve the bonding stability of the base layer and the surface layer.

[0039] The car seat provided in this application features a seamless, one-piece, non-seamless face mask that does not require connection to the inner frame 100 and filling block 200 on the front of the seat. The mask remains taut on the outer side of the inner frame 100 and filling block 200 due to its own elasticity. The mask can be fixed to the inner frame 100 or filling block 200 at the back of the seat or in a corner using methods such as zippers, sewing, bonding, or riveting. The filling block 200 is detachably connected to the inner frame 100, making it easy to repair or replace when the mask wears down or when the elasticity of the filling block in some areas decreases. Furthermore, different car interior environments can be created by changing the mask to meet the personalized needs of car occupants.

[0040] Example 2

[0041] This embodiment provides a seamless, one-piece, seamless face mask car seat, which uses a seamless, one-piece, seamless face mask with at least a base layer 301 and a surface layer 302 as the outermost structure of the seat. The manufacturing method of this car seat includes:

[0042] The inner frame 100 constitutes the main structure of the car seat. The filling block 200 is connected to the inner frame 100 to form an elastic cushioning structure. A seamless, one-piece, seamless face mask is fitted over the inner frame 100 and the filling block 200 to form a skin-friendly contact structure. The face mask is formed by vacuum forming to become a seamless, one-piece, seamless face mask that includes at least a base layer 301 and a surface layer 302. The production process includes: making a mold for a vacuum forming machine, the shape of which is similar to that of a car seat; laying a base fabric on the vacuum forming machine mold; adding additional materials on the base fabric; vacuum forming; the base fabric is vacuum formed to form the base layer 301 and the additional materials form the surface layer 302.

[0043] Conventional vacuum forming processes include laying raw material sheets on a mold, heating and softening, vacuum adsorption forming, and cooling and shaping. In the manufacturing method provided in this embodiment, the base fabric is used as the raw material sheet. Additional materials are added to the base fabric by means of coating or spraying. The additional materials are applied to the surface of the base fabric in the form of solid, semi-solid, or liquid. Then, during the heating and softening process of vacuum forming, the base fabric and the additional materials are fused together. Finally, after vacuum forming, a seamless, one-piece, traceless face mask with a base layer 301 and a surface layer 302 is obtained. The base fabric becomes the base layer 301 after forming, and the additional materials become the surface layer 302 after forming.

[0044] The seamless, one-piece, seamless face mask provided in this embodiment has additional materials applied to the base fabric by coating or spraying to form a surface layer, so that the face mask surface has no splicing marks or sewing marks, and the surface layer 302 is in contact with the user, making it comfortable and skin-friendly.

[0045] It is understandable that the base layer 301 and the surface layer 302 are not two physically separate, clearly defined layers, but rather two layers that can fuse together at the contact points. Furthermore, a buffer material can be added between the base layer 301 and the surface layer 302 to form a buffer layer, or an adhesive material can be added between the base layer 301 and the surface layer 302 to improve the bonding stability between the base layer and the surface layer.

[0046] In specific implementations, the base fabric material can be common blister packaging materials such as polyvinyl chloride (PVC) sheets, polyethylene terephthalate (PET) sheets, polypropylene (PP) sheets, polystyrene (PS) sheets, or glucono-galvanized (GAG) sheets. Alternatively, common fabrics such as nylon sheets or spandex sheets can be used, or a mixed-material sheet can be employed. Additional materials can be silicone or polyurethane (PU). This results in a seamless, one-piece, traceless face mask with a surface layer that offers advantages such as stable performance, skin-friendly comfort, and long lifespan.

[0047] To reduce processing difficulty, in a further embodiment, the seamless one-piece mask can be divided into a first seamless one-piece mask corresponding to the chair back and a second seamless one-piece mask corresponding to the chair seat. The first seamless one-piece mask and the second seamless one-piece mask are made independently, making the required vacuum forming mold shape simpler.

[0048] Example 3

[0049] This embodiment provides a seamless, one-piece, seamless face mask car seat, which uses a seamless, one-piece, seamless face mask having at least a base layer 301 and a surface layer 302 as the outermost structure of the seat. The manufacturing method of this car seat includes:

[0050] The inner frame 100 constitutes the main structure of the car seat. The filling block 200 is connected to the inner frame 100 to form an elastic cushioning structure. A seamless, one-piece, seamless face mask is fitted over the inner frame 100 and the filling block 200 to form a skin-friendly contact structure. The face mask is integrally formed by hot pressing, becoming a seamless, one-piece, seamless face mask comprising at least a base layer 301 and a surface layer 302. The production process includes: creating a mold for a hot press, the mold being shaped like a car seat; laying several sheet-like base fabrics on the hot press mold; connecting the several sheet-like base fabrics; adding additional materials to the base fabrics; and hot pressing to form the base layer 301 and the additional materials forming the surface layer 302. The connection of the several sheet-like base fabrics can be achieved by bonding or ultrasonic welding.

[0051] In the manufacturing method provided in this embodiment, the base fabric is used as a raw material sheet. Additional materials are added to the base fabric by means of coating or spraying. The additional materials are applied to the surface of the base fabric in the form of solid, semi-solid, or liquid. Then, during the heating and softening process of hot pressing in a hot press, the base fabric and the additional materials are fused together. Finally, after molding, a seamless, one-piece, traceless face mask with a base layer 301 and a surface layer 302 is obtained. After molding, the base fabric becomes the base layer 301, and after molding, the additional materials become the surface layer 302.

[0052] It is understandable that the base layer 301 and the surface layer 302 are not two physically separate, clearly defined layers, but rather two layers that can fuse together at the contact points. Furthermore, a buffer material can be added between the base layer 301 and the surface layer 302 to form a buffer layer, or an adhesive material can be added between the base layer 301 and the surface layer 302 to improve the bonding stability of the base layer 301 and the surface layer 302.

[0053] In specific implementations, the base fabric material can be common thermoforming materials such as epoxy resin sheets, phenolic resin sheets, and PEEK sheets. Additional materials can be silicone or polyurethane (PU). This results in a seamless, one-piece, traceless face mask with advantages such as stable performance, skin-friendly comfort, and long lifespan.

[0054] To reduce processing difficulty, in a further embodiment, the seamless one-piece seamless face mask can be divided into a first seamless one-piece seamless face mask corresponding to the chair back and a second seamless one-piece seamless face mask corresponding to the chair seat. The first seamless one-piece seamless face mask and the second seamless one-piece seamless face mask are made independently, making the required thermoforming mold shape simpler.

[0057] The inner frame 100 constitutes the main structure of the car seat. The filling block 200 is connected to the inner frame 100 to form an elastic cushioning structure. A seamless, one-piece, traceless mask is fitted over the inner frame 100 and the filling block 200 to form a skin-friendly contact structure. The mask includes a base layer 301 and a surface layer 302. The base layer 301 is formed by hot pressing or vacuum forming. Additional materials are added to the surface of the formed base layer 301, and the additional materials are cured to form the surface layer 302. The base layer 301 and the surface layer 302 together constitute the seamless, one-piece, traceless mask. The hot pressing or vacuum forming of the base layer 301 can be referred to in Examples 2 and 3.

[0058] After the base layer 301 is formed, the additional material is applied to the surface of the base layer 301 by coating or spraying, and then solidified to form the surface layer 302 by means of cooling solidification, solvent evaporation curing, dehydration curing, moisture curing, anaerobic curing, heat curing, microwave radiation curing or light curing.
