Description

Technical Field

[0001] This utility model relates to the field of seat back technology, specifically to a composite seat back cover. Background Technology

[0002] Seat back covers are decorative and protective accessories for seats. They are made of fabric, leather, or synthetic fiber materials and are designed to cover the back of a seat. They not only enhance the appearance of the seat but also effectively protect it from wear, stains, dust, and damage from daily use. Seat back covers are suitable for car seats, office chairs, and home chairs.

[0003] In the process of realizing this utility model, the inventors discovered that:

[0004] Existing seat back covers suffer from structural instability. When installed using simple elastic bands or ropes, they are prone to loosening, shifting, or even slipping off during use, affecting normal operation. Current solutions involve more robust fixing methods, such as a composite system combining buckles, Velcro, and elastic bands. Buckles provide precise positioning, while Velcro and elastic bands adapt to different seat sizes, ensuring the cover won't easily shift or slip off during use. In daily use, the cover frequently rubs against clothing and the body, causing ordinary fabrics to pill, snag, or tear. Especially in car seat use, friction from seatbelts accelerates wear, and insufficient internal impact resistance further shortens the cover's lifespan. Summary of the Invention

[0005] To address the problems existing in the prior art, this utility model provides a composite seat back cover, which aims to improve the problem that the friction of the seat belt accelerates the wear of the cover, and that the insufficient impact resistance inside the cover leads to a shortened service life.

[0006] Therefore, the technical solution of this utility model is as follows: a composite seat back cover, including a seat cover cover, the inside of which is provided with a reinforcing mechanism to improve the service life of the cover cover, and the rear side of the seat cover cover is provided with multiple connecting mechanisms; the reinforcing mechanism includes an impact-resistant layer, the front side of which is fixedly connected to the front side of the inner wall of the seat cover cover, and ultra-high molecular weight polyethylene fibers are fixedly connected to both the front and rear sides of the inner wall of the impact-resistant layer, multiple high-strength cotton ribs are fixedly connected to the left side of the inner wall of the impact-resistant layer, multiple polyester fiber ribs are fixedly connected to the right side of the inner wall of the impact-resistant layer, and a breathable layer is fixedly connected to the rear side of the impact-resistant layer, with multiple breathable grooves opened on the front side of the breathable layer, and a cushioning component is provided on the front side of the seat cover cover.

[0007] A further improvement to the above technical solution is that the connecting mechanism includes multiple connecting seats, the front sides of which are fixedly connected to the left and right rear ends of the chair cover, a rotating plate is rotatably connected to the left and right sides of the connecting seats, a locking block is fixedly connected to the rear side of the rotating plate, a locking groove is provided on the rear side of the connecting seat, elastic webbing is provided at the upper and lower rear ends of the chair cover, a connector is fixedly connected to the left and right front ends of the elastic webbing, the front side of the connector engages with the locking groove, a locking groove is provided on the left and right sides of the connector, and one side of the locking block engages with the locking groove.

[0008] A further improvement to the above technical solution is that the cushioning component includes a leather pad, the rear side of which is fixedly installed on the bottom front side of the chair cover, and an airbag layer is fixedly installed on the bottom front side of the chair cover.

[0009] A further improvement to the above technical solution is that a bamboo fiber board is fixedly connected to the rear side of the breathable layer, and multiple polyurethane pads are fixedly connected to the rear side of the bamboo fiber board.

[0010] A further improvement to the above technical solution is that the multiple high-strength cotton ribs and multiple polyester fiber ribs are all fixedly connected by needle and thread, and form a diamond-shaped mesh structure with the multiple polyester fiber ribs.

[0011] A further improvement to the above technical solution is that multiple rubber blocks are fixedly connected to the upper and lower sides of the multiple connecting seats, and the multiple rubber blocks are arranged symmetrically at equal intervals.

[0012] A further improvement to the above technical solution is that the connecting mechanism further includes multiple corner protectors, the rear sides of which are respectively fixedly connected to the left and right sides of the inner wall of the corresponding elastic webbing.

[0013] A further improvement to the above technical solution is that: both the left and right sides of the chair cover are fixedly connected with Velcro, and widened covers are pasted on the opposite sides of the two Velcro surfaces.

[0014] Beneficial effects: The composite seat back cover of this utility model, through the weaving and fixing of multiple ultra-high molecular weight polyethylene fibers, high-strength cotton ribs, and polyester fiber ribs, effectively forms a diamond-shaped mesh structure inside the cover, thereby improving its impact and tear resistance on the front side. This avoids the situation where insufficient impact resistance inside the cover leads to a shortened service life. At the same time, the connection of bamboo fiber board and polyurethane pad improves wear resistance and extends the service life of the cover. The rotation of multiple rotating plates allows the locking block to engage and fix with the corresponding locking groove, thereby completing the locking of the elastic webbing and the connector, completing the installation of the cover. Conversely, it can be disassembled. Thus, the quick disassembly and assembly of multiple connectors and connector seats improves the efficiency of cover assembly and disassembly, facilitating the disassembly and cleaning of the cover.

[0021] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings, but this embodiment should not be construed as a limitation of this utility model.

[0022] This utility model is as follows Figures 1 to 5 As shown:

[0023] A composite seat back cover includes a seat cover 1. The seat cover 1 has an internal reinforcing mechanism 2 to improve its service life. Multiple connecting mechanisms 3 are located on the rear side of the seat cover 1. The reinforcing mechanism 2 includes an impact-resistant layer 201. The front side of the impact-resistant layer 201 is fixedly connected to the front inner wall of the seat cover 1, effectively reducing external damage to the seat cover 1. Ultra-high molecular weight polyethylene fibers 202 are fixedly connected to both the front and rear sides of the inner wall of the impact-resistant layer 201, enabling the fabric to achieve lightweight, high strength, and impact resistance. Multiple high-strength cotton ribs 203 are fixedly connected to the left side of the inner wall of the impact-resistant layer 201, and multiple polyester fiber ribs 204 are fixedly connected to the right side of the inner wall of the impact-resistant layer 201. The cross-fixation of the high-strength cotton ribs 203 and the polyester fiber ribs 204 improves the tear resistance of the seat cover 1, further enhancing its internal strength.

[0024] The rear side of the impact-resistant layer 201 is fixedly connected to the breathable layer 205, and the front side of the breathable layer 205 is provided with multiple breathable grooves 206. The breathability of the fabric is improved by the arrangement of the breathable layer 205 and the multiple breathable grooves 206. The front side of the chair cover 1 is provided with a cushioning component 209.

[0025] In this technical solution, the reinforcing mechanism 2 inside the chair cover 1 enhances the performance and service life of the cover through a combination of multiple materials. The impact-resistant layer 201, as the core protective layer, is fixed to the front of the inner wall of the chair cover 1, directly resisting external impacts and friction, reducing damage to the chair cover 1. The ultra-high molecular weight polyethylene fibers 202 fixed to the front and back of the inner wall of the impact-resistant layer 201, with their light weight, high strength, and impact resistance, enhance the overall mechanical properties of the fabric and effectively disperse external impact forces. The high-strength cotton ribs 203 on the left side of the inner wall of the impact-resistant layer 201 and the polyester fibers on the right side... The fiber reinforcement 204 is cross-fixed to form a high-strength mesh structure, which improves the tear resistance of the fabric and further strengthens the internal strength of the chair cover 1. The breathable layer 205 connected to the back of the impact-resistant layer 201 has multiple breathable grooves 206 on its front side to create an air circulation channel, accelerate the dissipation of heat and moisture, improve the breathability of the fabric, and improve the comfort of use. The cushioning component 209 on the front of the chair cover 1 further cushions the external impact force on the basis of the impact-resistant layer 201, and works together to strengthen the various components of the mechanism 2 to improve the performance of the chair cover 1 in terms of protection and breathability, and extend its service life.

[0026] In this embodiment, the connecting mechanism 3 includes multiple connecting seats 301. The front sides of the multiple connecting seats 301 are respectively fixedly connected to the left and right rear ends of the chair cover 1, so that the chair cover 1 can be easily disassembled and reassembled with the connection of multiple connecting seats 301. Rotating plates 302 are rotatably connected to the left and right sides of the connecting seats 301. Locking blocks 303 are fixedly connected to the rear side of the rotating plates 302, so that the locking blocks 303 can lock with the corresponding locking grooves 307 when the rotating plates 302 rotate. The rear side of the connecting seat 301 is provided with a locking groove 304. Elastic webbing 305 is provided at both the upper and lower rear ends of the 1. Connectors 306 are fixedly connected to the left and right front ends of the elastic webbing 305. The elastic webbing 305 can be initially installed and connected by engaging the connectors 306. Then, under the rotation of the rotating plate 302, it is locked with the connectors 306. The front side of the connectors 306 engages with the engaging groove 304. Locking grooves 307 are provided on both the left and right sides of the connectors 306. One side of the locking block 303 engages with the locking groove 307, which improves the flexibility of the chair cover 1 during use and improves the efficiency of disassembly and assembly.

[0027] In this technical solution, multiple connecting seats 301 are fixed to the left and right rear ends of the chair cover 1 on their front sides. Each connecting seat 301 is rotatably connected to a rotating plate 302 on its left and right sides. The locking block 303 fixed to the rear side of the rotating plate 302 can change position as the rotating plate 302 rotates. The engaging groove 304 opened on the rear side of the connecting seat 301 is adapted to the connecting head 306 structure on the left and right sides of the front end of the elastic webbing 305 at the upper and lower rear ends of the chair cover 1. During installation, the connecting head 306 of the elastic webbing 305 is inserted into the engaging groove 304, completing the initial connection between the elastic webbing 305 and the connecting seat 301. Rotating the rotating plate 302 causes the locking block 303 to rotate until it aligns with and engages with the locking grooves 307 on the left and right sides of the connector 306, forming a double fixing structure. When disassembling, rotating the rotating plate 302 in the opposite direction causes the locking block 303 to disengage from the locking groove 307, allowing the connector 306 to be removed, thus enabling the quick disassembly of the chair cover 1. This design simplifies the disassembly and assembly process of the chair cover 1 by using the initial positioning of the engaging groove 304 and the connector 306, combined with the locking function of the rotating plate 302 and the locking block 303, thereby improving the flexibility and efficiency of use and facilitating daily cleaning and replacement.

[0028] In this embodiment, the cushioning component 209 includes a leather pad 2091, the rear side of which is fixedly installed on the bottom front side of the chair cover 1, and an airbag layer 2092 is fixedly installed on the bottom front side of the chair cover 1; a bamboo fiber board 207 is fixedly connected to the rear side of the breathable layer 205, and multiple polyurethane pads 208 are fixedly connected to the rear side of the bamboo fiber board 207; multiple high-strength cotton ribs 203 and multiple polyester fiber ribs 204 are all fixedly connected by needle and thread, and form a diamond grid structure with the multiple polyester fiber ribs 204;

[0029] In this technical solution, the connection between the leather pad 2091 and the airbag layer 2092 provides support and cushioning for the back, improving comfort. The connection between the bamboo fiber board 207 and multiple polyurethane pads 208 improves the wear resistance of the back of the cover. The diamond mesh structure formed by the high-strength cotton ribs 203 and polyester fiber ribs 204 improves the toughness of the impact-resistant layer 201 and enhances its tear resistance.

[0030] In this embodiment, multiple rubber blocks 308 are fixedly connected to the upper and lower sides of multiple connecting seats 301, and the multiple rubber blocks 308 are arranged symmetrically at equal intervals; the connecting mechanism 3 also includes multiple corner protectors 309, and the rear sides of the multiple corner protectors 309 are fixedly connected to the left and right sides of the inner wall of the corresponding elastic webbing 305 respectively; the left and right sides of the chair cover 1 are fixedly connected with Velcro 5, and widened covers 4 are pasted on the opposite sides of the two Velcro 5.

[0031] In this technical solution, the connection of multiple rubber blocks 308 improves the protection of the upper and lower sides of the connecting seat 301, the corner protector 309 protects the inside of the elastic webbing 305, and the connection of the Velcro 5 and the widened cover 4 increases the protection space of the chair cover 1.

[0032] The working principle of this utility model:

[0033] The reinforcing mechanism 2 inside the chair cover 1 enhances the performance and lifespan of the cover through a multi-layered composite structure, directly bearing the forces of external impact and friction, reducing damage to the chair cover 1. The ultra-high molecular weight polyethylene fibers 202 fixed to the front and back sides of the inner wall of the impact-resistant layer 201, utilizing their lightweight, high strength, and impact resistance, provide basic mechanical support for the fabric, effectively dispersing external impact forces. The high-strength cotton ribs 203 on the left side of the inner wall of the impact-resistant layer 201 and the polyester fiber ribs 204 on the right side are cross-woven and fixed, forming a diamond-shaped mesh structure. This structure relies on the high-strength cotton... The toughness of the rib 203 and the strength of the polyester fiber rib 204 enhance the tear resistance of the fabric and further improve the overall internal strength of the chair cover 1. The breathable layer 205 connected to the back of the impact-resistant layer 201 creates an air circulation channel through multiple ventilation slots 206, promoting the dissipation of heat and moisture, improving the breathability of the fabric, and enhancing the comfort of use. The cushioning component 209 on the front of the chair cover 1 further absorbs and cushions the impact of external forces on the basis of the impact-resistant layer 201, thus avoiding the problem of shortened service life due to insufficient impact resistance and extending the overall service life of the cover.

[0034] Furthermore, multiple connecting seats 301 are fixed to the left and right rear ends of the chair cover 1 on their front sides, forming the basic structure for disassembling and assembling the cover. Each connecting seat 301 is rotatably connected to a rotating plate 302 on its left and right sides. The locking block 303 fixed on its rear side can change position as the rotating plate 302 rotates. The engaging groove 304 on the rear side of the connecting seat 301 matches the connecting head 306 on the left and right sides of the front end of the elastic webbing 305 at the upper and lower rear ends of the chair cover 1. During installation, first, the connecting head 306 of the elastic webbing 305 is inserted into the engaging groove 304 of the connecting seat 301 to achieve initial positioning of the elastic webbing 305 and the connecting seat 301. Then, the rotating plate 302 is rotated, causing the locking block 303 to rotate to the left and right sides of the connecting head 306. The locking groove 307 is aligned and engaged to form a double fixation, completing the firm locking of the elastic webbing 305 and the connector 306, thereby realizing the installation of the face cover. When disassembling, the rotating plate 302 is rotated in the opposite direction to make the locking block 303 disengage from the locking groove 307, releasing the lock on the connector 306, so that the connector 306 can be taken out from the engaging groove 304, completing the disassembly of the face cover. This initial positioning of the engaging groove 304 and the connector 306, combined with the secondary locking structure of the rotating plate 302 and the locking block 303, simplifies the disassembly and assembly process of the face cover. With the synergistic effect of multiple connectors 306 and connector seats 301, the disassembly and assembly efficiency of the face cover is significantly improved, making it convenient for users to regularly disassemble and clean the face cover.
