[0037] To address the problems of existing seat assembly, which require a large amount of manual labor and have low assembly efficiency, the present invention provides a seat that simplifies the final assembly process, reduces labor costs, achieves good overall consistency, and improves production efficiency. The seat is further described below using a specific embodiment with accompanying drawings.

[0038] With the help of Figures 1 to 7 Describe the overall structure of the seat. Figure 1 and Figure 2 As shown, the seat according to the present disclosure includes an exterior assembly and a frame assembly 6 for installing the exterior assembly. The frame assembly 6 includes a backrest frame 61 and a seat cushion frame 62. The exterior assembly is divided into multiple assembly modules according to the seat area, including at least a backrest middle block assembly 2 and a seat cushion middle block assembly 5. In the present disclosure, the exterior assembly further includes a headrest assembly 1, two backrest side wing assemblies 3 arranged on both sides of the backrest middle block assembly 2, and two seat cushion side wing assemblies 4 arranged on both sides of the seat cushion middle block assembly 5, that is, a total of seven assembly modules. In addition, from Figure 1 and Figure 2Also visible are the side panels 7 covering the seat cushion wing assemblies 4 and the backrest panel 8 covering the back of the backrest frame 61. In the exterior assembly, the backrest center block assembly 2 and the seat cushion center block assembly 5 are also equipped with wiring harness assemblies. Depending on the functional design of the seat, some or all of the other assembly modules in the exterior assembly may also be equipped with wiring harness assemblies.

[0039] In the present disclosure, each assembly module in the exterior trim assembly comprises a foam component, a face cover assembly for enclosing the foam component, and a support member for supporting the foam component. The face cover assembly comprises at least a face cover. In the final assembled state, the face cover of the face cover assembly is connected to the support member, thereby securing the foam component to the support member. Furthermore, the support member with the face cover assembly and foam component is mounted on a corresponding portion of the frame assembly 6. Thus, each assembly module in the exterior trim assembly can be mounted on the frame assembly 6 as a preassembled assembly. In particular, the corresponding face cover is releasably connected to the corresponding support member at its edge.

[0040] The corresponding foam parts can be fixedly connected to the corresponding face cover assembly. In the present disclosure, the corresponding foam parts are integrally formed on the corresponding face cover assembly by an injection molding method. In an embodiment not shown, the corresponding foam parts can also be adhesively connected to the corresponding face cover assembly. Alternatively, in an embodiment not shown, the corresponding foam parts can also be connected to the corresponding face cover assembly through a hanging structure. In the case where the corresponding foam parts and the corresponding face cover assembly are fixed together in advance (especially pre-assembled together), the corresponding foam part-face cover assembly can be formed. For example, for the backrest middle block assembly 2, the following can be formed: Figure 3 and Figure 4 The foam part-cover assembly 26 shown is for the backrest center block assembly 2.

[0041] The support member 27 of the backrest middle block assembly 2 can exist in two forms, one of which is a plate-shaped member 271 (such as Figure 3 and Figure 4 As shown), and the other is a suspension spring bracket 272 (as shown Figure 5 As shown). The plate-like member 271 is usually a plastic member. However, the possibility of the plate-like member being constructed as a metal plate is not excluded. The same applies to the support member 58 (as shown) of the seat cushion middle block assembly 5. Figure 6 As shown in FIG, the support member 58 of the seat cushion middle block assembly 5 can also be constructed as a plate-shaped member or a suspension spring frame. The corresponding support members of the headrest assembly 1, the backrest side wing assembly 3 and the seat cushion side wing assembly 4 also exist in the form of plate-shaped members.

[0042] Combine Figure 7It can be seen that in the present disclosure, thanks to the fact that the exterior decoration assembly is divided into several independent assembly modules, these assembly modules can be assembled on the corresponding frame assembly in a cost-saving, efficient and quality-stable manner through automated assembly. When assembling the seat of the present disclosure, the backrest center block assembly 2 can be first assembled on the backrest frame 61. Then the backrest side wing assembly 3 can be assembled on the backrest frame 61 and the seat cushion center block assembly 5 can be assembled on the seat cushion frame 62. Then the seat cushion side wing assembly 4 can be assembled on the seat cushion frame 62. Subsequently, the headrest assembly 1 can be assembled on the backrest frame 61, and the side panels 7 can be assembled on the seat cushion side wing assembly 4 and the seat back panel 8 can be assembled on the backrest frame 61 from the back. Finally, the seat of the present disclosure is formed.
