[0032] The preferred embodiments of the present utility model are given below in conjunction with the accompanying drawings and described in detail.

[0033] like Figure 1 As shown, the comfort system installation structure according to a preferred embodiment of the utility model includes a back plate 1, a comfort system 2, a support layer 3 and a foam material 4, wherein the back side (i.e., side B) of the foam material 4 is installed on the back plate 1, and the comfort system 2 is installed and fixed on the back side of the foam material 4 through the support layer 3, so that the noise generated by the comfort system 2 is directly absorbed by the foam material 4, vibration isolation and noise reduction are achieved, and abnormal noise is eliminated. In the specific installation process, the comfort system 2 is first fixed to the support layer 3, and the two form a subassembly, and then the subassembly is fixed, buckled or hung to the foam material 4.

[0034] In this embodiment, the back panel 1 is a seat sheet metal, the comfort system includes massage components such as an air pump, and the comfort system 2 is not directly connected to the back panel 1, and is effectively physically isolated, thereby effectively avoiding the vibration of the comfort system 2 causing the sheet metal to vibrate and the noise that may be generated thereby, so that the seat amplitude is reduced, thereby improving the passenger discomfort caused by the matching factor between the body frequency and the seat frequency. It should be understood that the specific structure of the back panel 1 mentioned here is only an example and not a limitation, and can be provided as a backrest frame or a cushion frame. It should be understood that the sheet metal mentioned here is only an example and not a limitation, and it is feasible to replace it with a hard back panel or a honeycomb panel.

[0035] In this embodiment, the comfort system 2 includes an air valve 21, an air pipe 22 and an air bag 23, wherein the air bag 23 connected to the air valve 21 through the air pipe 22 is arranged at a position adjacent to the front of the foam material 4, so as to provide a massage function for the passenger through the air bag 23. In addition, the comfort system 2 includes a foam block or a sticky cloth 24, which is arranged on the back of the air valve 21. The comfort system 2 is separated from the back plate 1 by the foam block or the sticky cloth 24, further avoiding the vibration of the comfort system 2 causing the sheet metal to shake and the noise that may be generated thereby. It should be understood that the specific structure of the comfort system 2 mentioned here is only an example and not a limitation. In fact, there is a gap between the comfort system 2 and the back plate 1 near the foam block or the sticky cloth 24. As the human body sinks into the foam material, the comfort system 2 moves backward following the foam material 4, which can effectively increase the penetration of the human body and improve the comfort and whipping performance.

[0036] In this embodiment, the support layer 3 is a cloth mounting sheet, which is a mounting sheet made of short-fiber cotton material, and is provided with a plurality of connectors 31 in the form of extensions, which are formed along the edge of the cloth mounting sheet or formed outward from the support layer 3. Figure 2 As shown, the comfort system 2 is installed on the support layer 3. Specifically, the air valve 21 is installed on the back of the support layer 3, the air pipe 22 is wound from the back to the front and fixed in position by a partial extension (connector 31), and the air bag 23 is installed on the front of the support layer 3. It should be understood that the material and shape of the support layer 3 mentioned here are only examples and not limitations. For example, the cloth installation sheet can be replaced with a felt board. Figure 3 As shown, in the prior art, the air valve 21 of the comfort system 2 is installed on the back plate 1, and the air bag 23 is arranged on the front of the foam material 4 and the rear of the face cover 4a. In the process of connecting the air pipe 22 connected to the air valve 21 with the joint 23a of the air bag 23, due to the narrow operating space, it brings many inconveniences to the installation of the air pipe 22 and the wiring harness insertion work, and even may cause leakage and other problems. Figure 4 As shown, in the present invention, the comfort system 2 is first installed with the support layer 3 to form a subassembly. At this time, there is no problem of limited operating space. The installation of the air pipe 22 and the insertion of the wiring harness are unobstructed, which has obvious assembly convenience. In other words, the comfort system 2 is installed on the B side of the foam material 4 through the support layer 3, assembled into an integrated backrest assembly and then directly installed on the back plate 1. The assembly is simple and reliable, which improves the assembly efficiency and effectively avoids the problem that the comfort system 2 in the prior art is directly installed on the back plate 1, and it is necessary to connect various wiring harnesses and pipes of the comfort system 2 in the narrow space formed by the back plate 1 and the foam material 4, which has low functional reliability and long assembly time.

It should be understood that the mounting plate of the support layer 3 can be a felt plate or a plastic plate. In particular, the plastic plate of the support layer 3 has a weakening structure 32 in the form of a transverse groove or an edge recessed groove, which minimizes the sense of foreign matter / presence (such as a weak sense of backrest pressure) while providing the required installation strength, thereby providing passengers with a higher riding comfort experience. It should be understood that the embedded plate of the foam material 4 can be a plastic plate or a metal plate. It should be understood that the fasteners here are detachable connectors, including buckles, C-rings, cable ties, rivets or screws, etc.

[0039] In fact, the material of the supporting layer 3 can be cloth, such as non-woven fabrics or felt fabrics made of short fibers or filaments of synthetic fibers such as PP, PET and natural fibers such as cotton and linen through combing, needle punching, hot rolling and other processes; it can also be plastic, such as ABS, PCABC, PP+L / SGF, PVC, PP, PE, PC, PA66, PA6, PA66+GF, PA6+GF, etc.; it can also be metal.
