[0027] like Figure 1-6 As shown, the present invention provides a seat back, which includes a backrest panel 1 and a map pocket 2. The backrest panel 1 is provided on a preset side of the seat back, and the map pocket 2 is fixed to the backrest panel 1.

[0028] The backrest panel 1 is provided with a first groove, the shape of which matches the shape of the map bag 2, and the map bag 2 is embedded in the first groove; the backrest panel 1 is also provided with a slot 4, and the bottom of the map bag 2 is provided with a buckle 3, the buckle 3 matches the shape of the slot 4, and the buckle 3 is engaged in the slot 4.

[0029] The map pocket 2 is provided with a protrusion 5 on the side near the back panel 1, and the protrusion 5 is fixedly provided on the top of the map pocket 2; the back panel 1 is also provided with a second groove 6, the size of the second groove 6 is matched with the size of the protrusion 5, and the protrusion 5 is embedded in the second groove 6.

[0030] For example, such as Figure 1 and Figure 2 As shown, the aforementioned seat back can include a backrest panel 1 and a map pocket 2. The backrest panel 1 can be disposed on a predetermined side of the seat back, and the map pocket 2 can be fixed to the backrest panel 1. The predetermined side can be the side away from the passenger's back. The backrest panel 1 is provided with a first groove, the shape of which matches the shape of the map pocket 2, allowing the map pocket 2 to be embedded in the first groove. The overall shape of the first groove can be larger than the map pocket 2, so that the map pocket 2 can be embedded in the backrest panel 1, avoiding the occupation of additional space and avoiding the outward protrusion design of the map pocket 2, thus optimizing the spatial structure design of the seat back.

[0031] For example, such as Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the bottom of the map bag 2 can be provided with a buckle 3, and the back panel 1 is provided with a slot 4 that matches the shape of the buckle 3, so that the buckle 3 can be snapped into the slot 4, realizing the installation and fixation between the map bag and the back panel 1. Specifically, a buckle 3 can be provided on each of the two bottom sides of the map bag 2, and a slot 4 is provided at the corresponding position on the back panel 1. By setting the buckles 3 on both sides of the map bag 2, the connection structure between the map bag 2 and the back panel 1 can be made more stable and reliable.

[0032] For example, the top of the map bag 2 may also be provided with a protrusion 5, and a second groove 6 may be provided at the corresponding position on the back panel 1, so that the protrusion 5 can be embedded in the second groove 6. When the map bag 2 is not in use, it can fit completely against the back panel 1, avoiding the occupation of extra space. In addition, when the map bag 2 is in use, the protrusion 5 can increase the storage area of ​​the map bag 2, improving its practicality. Specifically, the protrusion 5 may be provided on both sides of the top of the map bag 2, and a second groove 6 may be provided at the corresponding position on the back panel 1. Placing the protrusion 5 on both sides can prevent damage to the items during storage and reduce the impact on the items inside the map bag 2.

[0033] For example, the map pocket 2 described above can be injection molded from ABS + 20% glass fiber material (ABS: Acrylonitrile Butadiene Styrene), with a dimensional tolerance of ±0.1mm. By setting the map pocket 2 as an embedded plastic plate, replacing the traditional flexible material, structural strength can be effectively improved, increasing resistance to compression and impact. Furthermore, a standard-sized atlas (210mm × 297mm) can be placed in the map pocket 2 of the seat back to verify the smoothness of retrieval and placement, as well as its load-bearing stability.

[0034] Furthermore, a pin is provided on the side of the backrest panel 1 away from the map pocket 2, the pin is fixedly connected to the backrest panel 1, and the pin passes through the buckle 3.

[0035] For example, a pin is provided on the side of the back panel 1 away from the map bag 2, that is, on the inner side of the back panel 1. When installing the map bag 2, the buckle 3 on the map bag 2 is inserted into the corresponding slot 4 on the back panel 1, and then the pin is inserted to fix it, thereby fixing the map bag 2 to the back panel 1. In addition, the buckle 3 can rotate a certain angle when the map bag 2 is pulled out, so as to store the items through the cooperation between the various components.

[0036] This utility model, by setting a pin, can fix the map bag 2 and the back panel 1 together when the buckle 3 on the map bag 2 is inserted into the corresponding slot 4 on the back panel 1, thus preventing it from falling off.

[0037] Furthermore, connectors are provided on both sides of the aforementioned slot 4, and the connectors are provided with through holes, through which the pins are connected to the aforementioned buckles 3.

[0038] For example, opposite connectors can be provided on both sides of the aforementioned slot 4. Pins are inserted into the through holes on the connectors to fix the map pocket 2 to the backrest 1, making the structure of the seat back more stable and preventing it from falling off and affecting the user experience. Specifically, the connectors are provided on the side of the backrest 1 away from the map pocket 2, that is, on the inner side of the backrest 1.

[0039] This utility model enables the map pocket 2 to be fixed to the backrest 1 by setting connectors on both sides of the slot 4, making the structure of the seat back more stable.

[0040] Furthermore, the distance between the aforementioned connecting members that are arranged opposite each other is a third distance, and the length of the aforementioned pin is greater than the aforementioned third distance.

[0041] For example, the distance between two connectors that are opposite each other on the same slot 4 is the third distance. The length of the pin is greater than the third distance to ensure that the pin can be fully inserted, thereby fixing the buckle 3 on the map bag 2 to the corresponding slot 4 on the back panel 1.

[0042] This invention ensures that the pin is fully inserted and prevents it from falling out by making the length of the pin greater than the distance between two connectors that are opposite each other in the same slot 4.

[0043] Furthermore, an elastic band is provided on the aforementioned boss 5, and a connecting through hole is provided on the aforementioned second groove 6. The connecting through hole penetrates the aforementioned backrest 1, and the aforementioned elastic band passes through the aforementioned connecting through hole and is fixedly connected to the side of the aforementioned map pocket 2 away from the aforementioned backrest 1.

[0044] For example, such as Figure 6 As shown, the aforementioned boss 5 can be a hollow structure, and the second groove 6 is provided with a connecting through hole. An elastic band can be provided on the boss 5. The elastic band can be tied to the boss 5 through the hollow part of the boss 5, and pass through the connecting through hole on the second groove 6 to be fixed to the other side of the backrest 1, further realizing the fixed connection between the map pocket 2 and the backrest 1. The use of the elastic band can facilitate the pulling out and resetting of the map pocket 2, improving the ease of use of the map pocket 2. In addition, the aforementioned elastic band can also be other elastic components, such as elastic bands, elastic ropes, etc.

[0045] By incorporating an elastic band, this invention not only further secures the map bag 2 and the backrest 1, but also facilitates the pulling out and resetting of the map bag 2, thus improving its ease of use.

[0046] Furthermore, a self-tapping screw is provided on the side of the back panel 1 away from the map pocket 2, and the elastic band passes through the connecting hole and is fixedly connected to the self-tapping screw.

[0047] For example, a self-tapping screw is provided on the side of the backrest panel 1 away from the map pocket 2. An elastic band passes through the connecting hole to the inside of the backrest panel 1 and is then connected to the self-tapping screw, thus achieving a fixed connection between the map pocket 2 and the backrest panel 1. Furthermore, a self-tapping screw is a fastener that can create its own threads during screwing, eliminating the need for pre-drilling and greatly simplifying the installation process. Self-tapping screws are also convenient and quick to install, effectively improving assembly efficiency. In addition, the self-tapping screw can be tightly connected to the plastic plate; when screwed into the plastic plate, its threads form a tight engagement with the plastic plate. This engagement allows the self-tapping screw to withstand greater tensile and shear forces, providing a robust connection and ensuring the reliability of the connection structure.

[0048] This invention, by setting self-tapping screws on the side of the back panel 1 away from the map pocket 2, not only achieves a stable connection between the map pocket 2 and the back panel 1, but also effectively simplifies the installation steps and improves assembly efficiency.

[0049] Furthermore, the distance from the self-tapping screw to the bottom of the backrest panel 1 is the first distance, and the distance from the slot 4 to the bottom of the backrest panel 1 is the second distance. The first distance is greater than the second distance.

[0050] For example, the distance from the self-tapping screw to the bottom of the backrest panel 1 is the first distance, and the distance from the slot 4 on the backrest panel 1 to the bottom of the backrest panel 1 is the second distance. The first distance can be set to be less than the second distance so that the connection structure between the map bag 2 and the backrest panel 1 is more stable. Moreover, through the elasticity of the elastic band, the map bag 2 can increase its storage space and improve its practicality when pulled out.

[0051] This invention enables the connection structure between the map bag 2 and the back panel 1 to be more stable and reliable, improves the overall quality of the map bag 2, and extends its service life.

[0052] Furthermore, the thickness of the aforementioned backrest panel 1 is 2.5mm ± 0.1mm.

[0053] For example, the backrest panel 1 can be injection molded from ABS engineering plastic (Acrylonitrile Butadiene Styrene), with a thickness of 2.5mm ± 0.1mm. Grooves can be pre-drilled on the backrest panel 1 to facilitate the installation and fixation of the map pocket 2. Furthermore, the use of plastic sheeting for the backrest panel 1 enhances its resistance to pressure and impact.

[0054] This invention optimizes the structural design of the seat back, ensuring its structural strength while avoiding taking up extra space, thus providing passengers with more spacious seating.

[0055] Furthermore, the aforementioned backrest panel 1 is a one-piece molded structure.

[0056] For example, the backrest panel 1 is manufactured using an injection molding process, which effectively reduces the number of parts and simplifies the assembly process. Specifically, the backrest panel 1 can be injection molded from ABS + 20% glass fiber material, with a dimensional tolerance of ±0.1mm.

[0057] By designing the backrest panel 1 as an integrally formed structure, the number of parts of the backrest panel 1 can be effectively reduced, making the preparation simpler and more convenient, which is conducive to large-scale production and assembly.

[0058] In one exemplary embodiment, the present invention also provides a seat having a seat back as described above.
