The detailed structure of the present invention will be further described with reference to the accompanying drawings and the detailed description.

Referring to fig. 5, the three-dimensional patchwork structure of the top cover mainly comprises a first top cover sheet 201, a second top cover sheet 202, a supporting strip 210 and a patchwork line 200. The piece line is worn to establish in proper order on the one end of support bar 210, the first cut-parts 201 of face cover and the one end of face cover second cut-parts 202, and the other end of the first cut-parts 201 of face cover turns over around support bar 201 and turns over and taut.

Referring to fig. 6 and 7, the top expanded surface of the supporting bar 210 is long, and the structure thereof is composed of a tubular portion 211 and a positioning portion 212. The positioning portion 212 is provided above the tubular portion 211, and includes a positioning end portion 212a and a positioning root portion 212 b. The positioning portion 212 is connected to the tubular portion 211 by a positioning root portion 212b, both of which are formed by an integral molding process. The section of the tubular part 211 is circular, and the diameter L of the tubular part is larger than the thickness of the positioning part 212, so that when the fabric is wrapped around the supporting bar 210, the fabric is supported by the tubular part 211 to form an arc-shaped flanging shape. The supporting strip 210 is made of soft rubber, preferably PVC.

Referring to fig. 8 and 9, another embodiment of the supporting strip 210 is that the positioning end 212a is wavy and zigzag, so that after the supporting strip 210 is bent, the positioning part 212 is not easy to become wavy due to squeezing, and the surface of the sleeve is irregular and bulges, which causes appearance problems.

Referring to fig. 10-12, when the present invention is assembled, the B side of the first panel 201 of the cover faces upward, the a side of the second panel 202 of the cover faces upward and is placed under the first panel 201 of the cover, and the support strip 210 is placed over the first panel 201 of the cover. The end 201a of the first cut piece of the surface cover and the end 202a of the second cut piece of the surface cover are respectively arranged at the front ends of the first cut piece 201 of the surface cover and the second cut piece 202 of the surface cover. After aligning the first panel end 201a of the cover, the second panel end 202a of the cover and the positioning end 212a, sewing the sewing thread 200 at one side of the positioning part 212 close to the tubular part 211, and fixing the three together by the sewing thread 200 passing through the support bar 210, the first panel 201 of the cover and the second panel 202 of the cover. Finally, the first cut piece 201 of the surface cover is turned over anticlockwise around the tubular part 211 to form a three-dimensional modeling structure.

The second embodiment of the present invention with reference to fig. 13 is: the setting passes the ornamental line 200a of the first cut-parts 201 of the face cover on upper strata, location tip 212a, the first cut-parts 201 of the face cover of lower floor and the second cut-parts 202 of face cover in proper order, and ornamental line 200a is located the left side of piece line 200 for can form the molding that the strip of taking the ornamental line draws the form of rolling on the face cover, promote the molding grade.

With reference to fig. 14 to 17, in the application of the structure of the present invention, the first cut segment 201 and the second cut segment 202 are supported by the supporting bars 201, so as to shield the splicing lines 200 at the splicing position, thereby preventing the lines from being exposed, and effectively avoiding the serpentine appearance problem at the splicing position. On the other hand, after the first cut segment 201 of the cover is turned around the supporting bar 201, a step with a length of L is formed compared with the original structure (fig. 2) to shield the original 60% of the backrest 20 and the C-pillar 30; a gap between 40% backrest and 60% backrest.
