[0010] Advantages and beneficial effects of the present utility model:

[0011] (1) The present utility model changes the internal structure of the B side of the original cover, forming a new way to fix and support the cover. By changing the traditional way of tightening the protective surface into a new reasonable fixing and supporting way, it can not only show a good visual effect of the B side, but also prevent the protective surface from deforming prematurely due to long-term use, maximizing the beautification of the seat appearance.

[0012] (2) The support structure provided by the present utility model stitches a sandwich layer in the core part of the B side, places a PP board in the sandwich layer, and adds six clamping strip fixing points on both sides. The B-side skin of the seat is connected to the backrest skeleton through the clamping strips. This structure can make the B side of the seat skin more plump, flat and not easy to deform (with aesthetic property); it not only saves the shaping time in the later assembly stage (with assembly efficiency improvement), but also can effectively improve the appearance retention of the seat skin (with usability).

[0013] (3) The interlayer on the back of the core cut piece of the present utility model is composed of a main interlayer with an opening facing downwards and two bottom interlayers with openings facing upwards. This design facilitates the assembly of the PP board and does not affect the overall structure of the surface cover at the same time. Description of the Drawings
