[0058] Reference will now be made in detail to the various embodiments of the application, the examples of which are shown in the accompanying drawings and are described below. Although the application will be described in conjunction with the exemplary embodiments, it should be appreciated that this specification is not intended to limit the application to those exemplary embodiments. On the contrary, the application is intended to not only cover these exemplary embodiments, but also to cover various alternative forms, modified forms, equivalent forms and other embodiments that may be included in the spirit and scope of the application defined by the appended claims.

[0059] In the subsequent description, the orientation or position relationship indicated by "longitudinal", "lateral", "upper", "lower" or other directional terms is based on the orientation or position relationship shown in the drawings, and is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the device or component referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application.

[0060] At the same time, the present application uses specific words to describe the embodiments of the present application. For example, "one embodiment" and / or "an embodiment" means a certain feature, structure or characteristic related to at least one embodiment of the present application. Therefore, it should be emphasized and noted that "one embodiment" or "an embodiment" mentioned twice or more in different positions in this specification does not necessarily refer to the same embodiment. In addition, certain features, structures or characteristics in one or more embodiments of the present application can be appropriately combined.

[0061] As mentioned above, in the current seat solutions, the backrest of the seat is generally not replaceable separately, that is, within the service life of the seat, the backrest is generally unchanged, and if the backrest is damaged, the entire seat is generally replaced directly. Therefore, it is difficult for existing solutions to meet the personalized needs of users. In a comparative solution to this problem, a seat back module with a frame body formed of a whole board is used, and the whole board is connected to the seat back frame. However, the inventor found that this comparative solution will cause the seat to be heavier and the comfort needs to be improved.

[0062] Continuing with the above, the inventor of the present application has conducted in-depth research and proposed a new seat back module and seat to address the above issues. Through the setting of the seat back module, the seat back module can be replaced as a whole to meet the user's personalized needs for replacing the back module. In addition, the structure of the frame body composed of longitudinal beams and transverse beams is lighter and more comfortable than the structure of the frame body composed of a whole plate. In addition, for seat development work, the length of the longitudinal beam and the number of sections of the transverse beam can be adjusted accordingly to meet the needs of seats of different lengths, saving time for seat development.

[0063] The seat back module described in the following embodiments is applicable to automobile seats to meet the personalized needs of users to replace the back module, but is not limited to this. For example, it can be applied to other transportation applications, such as engineering machinery, railway trains, ships, airplanes, etc. In addition, the application scenarios of seats are not limited to transportation, for example, they can also be applied to seats in fixed places, such as venues, auditoriums, cinemas, etc., as long as the seat can be applied to the seat back module disclosed in the embodiments of this application.

[0064] refer to Figure 1 As shown, the seat 100 includes a seat back frame 1 and a seat back module 2, wherein Figure 1 As shown, the seat back module 2 can be integrally and detachably connected to the seat back frame 1 to form the backrest portion of the seat 100. In addition, the seat 100 generally also includes a cushion portion, but this is not the focus of this application, so it will not be introduced in detail here.

[0065] refer to Figure 2A , Figure 2B as well as Figure 3A , Figure 3B As shown, the seat back module 2 includes a frame 21, which includes a shoulder 211, a connecting portion 212, and a frame body 213 extending between the shoulder 211 and the connecting portion 212; the frame body 213 is located within the area 101 defined by the seat back frame 1, and the frame body 213 includes a plurality of longitudinal beams 2131 extending along the length direction of the seat back frame 1, and a transverse beam 2132 arranged between adjacent longitudinal beams 2131 and extending along the width direction of the seat back frame 1; the shoulder 211 provides support for the shoulder of the seat 100, and the connecting portion 212 can be detachably connected to the seat back frame 1. When replacing, the seat back module 2 can be connected or disconnected with the seat back frame 1 by connecting or disconnecting the connecting portion 212 with the seat back frame 1.

[0066] It can be understood that the frame 21 of the seat back module 2 and the seat back frame 1 are two different components. The seat back frame 1 refers to the main frame of the seat. In addition, the seat back module 2 generally also includes a surface cover 22, which provides the surface of the backrest of the seat. The surface cover is not the focus of this application, so it will not be introduced in detail here.

[0067] Here, extending along the length direction of the seat back frame 1 and extending along the width direction of the seat back frame 1 are not limited to being substantially consistent with the length direction of the seat back frame 1 and the width direction of the seat back frame 1 as shown in the figure, and for example, there may be a certain angle, which is not limited to this. For example, the transverse beam 2132 shown in the figure has a bent structure.

[0068] As shown in the figure, the specific structures of the longitudinal beam 2131 and the transverse beam 2132 can both be steel wire structures. Such a structure is simple and low in cost, but it is not limited to this. For example, it can also be other materials, such as carbon fiber, magnesium aluminum alloy and other materials.

[0069] The beneficial effects of the above-described embodiments include, but are not limited to, the seat back module can be replaced as a whole through the setting of the seat back module to meet the user's personalized needs for replacing the back module, and the structure of the frame body composed of longitudinal beams and transverse beams is lighter and more comfortable than the structure of the frame body composed of a whole plate. In addition, for seat development work, the length of the longitudinal beam and the number of sections of the transverse beam can be adjusted accordingly to meet the needs of seats of different lengths, saving time for seat development.

[0070] Continue to refer Figure 3A as well as Figure 3B ,as well as Figure 5 As shown, in some embodiments, the longitudinal beam 2131 and the transverse beam 2132 are overlapped structures, and the longitudinal beam 2131 and the transverse beam 2132 are connected by heat curing through an injection molded part 2133. The beneficial effect of such a setting is that its structure is simple and reliable, and the processing technology is simple, for example, there is no need to use a welding process to connect the longitudinal beam 2131 and the transverse beam 2132. And the inventor has found through testing that the strength of heat curing fixation can also meet the strength requirements.

[0071] Continue to refer Figure 3A as well as Figure 3B As shown, the injection molded part 2133 provides a mounting structure 2134 for setting the mounting panel 214. The mounting panel 214 can be used to install accessories, such as a fan 215 for achieving seat ventilation, but it is not limited to this. The accessories can also include components such as installing pneumatic valves, air pumps, air bags, and vibration units. The air pump can provide an air source for the air bag of the seat to achieve functions such as massage through the air bag, further improving the user experience. However, the structure of the mounting structure 2134 provided by the injection molded part 2133 is simplified, and there is no need to adopt a structure with more parts such as threaded connection, which facilitates the installation of the mounting panel 214 to the frame body 213. It can be understood that the mounting structure 2134 is not limited to being used only for setting the mounting panel 214. For example, the mounting structure 2134 can also be used to fix the surface cover 22.

[0072] Continue to refer Figure 3A as well as Figure 3BAs shown, in some embodiments, the specific structure of the mounting structure 2134 can be a first protrusion 2135 along a plane perpendicular to the longitudinal beam 2131 and the transverse beam 2132, and / or a second protrusion 2136 extending along the width direction of the seat back frame 1. For example, the first protrusion 2135 can be plugged into the notch 2141 provided in the mounting panel 214, and the second protrusion 2136 can further expand the contact area with the mounting panel 214, thereby further improving the stability of the mounting.

[0073] refer to Figure 3A as well as Figure 3B As shown, in some embodiments, the shoulder 211 may include a shoulder base 2111 and support members 2112 extending outward from both sides of the shoulder base 2111, and the extension direction may be various directions, such as the width direction, the length (height) direction, and the front-back direction. Figure 3A as well as Figure 3B As shown, the structure of the support member 2112 includes a closed structure surrounded by steel wires, such as the closed square structure shown in the figure, but it is not limited. It can be understood that the structure of the shoulder 211 can also only have the shoulder base 2111, and the structure of the support member 2112 can also be adjusted, so that the seat back module 2 with different shoulder support effects can be replaced by adjusting the structure of the support member 2112. For specific effects, please refer to Figure 4A , Figure 4B As shown in Figure 4A In the structure of the seat back, the corresponding structure of the frame 21 is that the shoulder 211 only includes the shoulder base 2111, and the shoulder support area corresponding to the seat back is the first area 1001. Figure 4B In the structure of the seat back portion shown, the structure of the corresponding frame 21 is that the shoulder 211 includes a shoulder base 2111 and support members 2112 extending outward from both sides of the shoulder base 2111, and the shoulder support area corresponding to the seat back portion is the second area 1002. Obviously, the width of the second area 1002 is greater than that of the first area 1001, and the shoulder support effects provided by the two to the user are different.

[0074] As above, reference Figure 5 As shown, in some embodiments, the present application also provides a method for manufacturing a seat, comprising:

[0075] A plurality of longitudinal beams 2131 and a plurality of transverse beams 2132 are provided, and the transverse beams 2132 are overlapped with adjacent longitudinal beams 2131 in parallel, and one transverse end of the transverse beam 2132 is overlapped with one longitudinal beam 2131, and the other transverse end is overlapped with another longitudinal beam 2132, so as to form a first intermediate member;

[0076] The intermediate piece is placed in the injection mold, and the overlap position of the transverse beam 2132 and the longitudinal beam 2131 is insert-molded, so that the injection molded piece 2133 is connected to the longitudinal beam 2131 and the transverse beam 2132 by heat curing to form the frame body 213;

[0077] A shoulder portion 211 is connected to one side of the frame body 213, and a connecting portion 212 is connected to the other side to form a frame 21;

[0078] A surface cover 22 is provided on the surface of the frame 21 to form a seat back module 2;

[0079] The seat back module 2 is detachably connected to the seat back frame 1 .

[0080] It is understood that flow charts are used in the present application to illustrate the operations performed by the system according to the embodiments of the present application. It should be understood that, according to the actual situation, the previous or following operations are not necessarily performed precisely in order. Other operations may also be added to these processes, or one or more operations may be removed from these processes.

[0081] For example, in some embodiments, between the steps of forming the frame 21 and setting the surface cover 22, after forming the frame 21, the installation panel 214 is installed on the injection molded part 2133, accessories are installed on the installation panel 214, and then the surface cover 22 is set on the surface of the frame 21 to form the seat back module 2. This simplifies the assembly process of setting the installation panel 214 and the fan 215.

[0082] In addition, as described above, the seat back module 2 can be equipped as a separate component, for example, a single seat can correspond to multiple different seat back modules 2, and users can replace different seat back modules 2 according to personalized needs. For example, the structure of the shoulder 211 described above can be different, so that the seat back module 2 with different shoulder support areas of the seat. That is, the seat back module 2 described above can be detachably connected to the seat back frame 1 as a whole to form the backrest of the seat 100; wherein: the seat back module 2 includes a frame 21, the frame 21 includes a shoulder 211, a connecting portion 212, and a frame body 213 extending between the shoulder 211 and the connecting portion 212; the frame body 213 is used to be arranged within the area 100 defined by the seat back frame 1, and the frame body 213 includes a plurality of longitudinal beams 2131 extending along the length direction, and a transverse beam 2132 arranged between adjacent longitudinal beams 2131 and extending along the width direction; the shoulder 211 provides support for the shoulder of the seat 100, and the connecting portion 212 can be detachably connected to the seat back frame 1.

[0083] In summary, the beneficial effects of the seat, manufacturing method and seat back module introduced in the above embodiments include but are not limited to that, through the setting of the seat back module, the seat back module can be replaced as a whole to meet the personalized needs of users to replace the back module, and the structure of the frame body composed of longitudinal beams and transverse beams is lighter and more comfortable than the structure of the frame body composed of a whole plate. In addition, for the seat development work, the length of the longitudinal beam and the number of sections of the transverse beam can be adjusted accordingly to meet the needs of seats of different lengths, which saves time for seat development, and the manufacturing process is relatively simple and the cost is low.
