The left side and right side on middle surface cover plate base is respectively pruned an oblique angle, the oblique angle in left side from the left bottom of base a bit
The lower tilt of lower side to the left, some lower tilt of lower side to the right of the oblique angle on right side from the bottom right side of base, institute
The vertical height for stating oblique angle is all not more than 30mm, and the horizontal width at the oblique angle is all not more than 3mm;
Surface cover is covered by the left side, right side set, middle surface cover and bottom surface set are constituted, left side set, right side set, middle surface cover and bottom surface set point
It is not coated on outside left side cage plate, right side cage plate, middle surface cover plate and bottom surface cage plate;
It is fitted in respectively on backrest and seat basin after surface cover plate outer cladding surface cover.
The described automotive seat for preventing surface cover fold, is characterized in that:Lower-left side and bottom right side all for central angle not
Circular arc more than 60 °.
The described automotive seat for preventing surface cover fold, is characterized in that:Surface cover is from velvet or polyurethane(That is poly
Urethane, abbreviation PU)Leather.
The present invention is by a hypotenuse of pruning at middle surface cover plate bottom corners so that surface cover entirely docile can exist when coating
Surface cover plate surface, eliminates buckling phenomena, and not only outward appearance is more attractive in appearance, and extends service life.
The invention has the beneficial effects as follows:Simple structure, convenient for production, any surface finish is smooth.

Embodiment 1
A kind of automotive seat for preventing surface cover fold, including backrest 1, seat basin 2, surface cover plate 3 and surface cover 4, such as Fig. 1~Fig. 6
Shown, concrete structure is:
One side of present basin 2 is fixed in the bottom of backrest 1;
Surface cover plate 3 as shown in Fig. 2 be made up of left side cage plate 31, right side cage plate 32, middle surface cover plate 33 and bottom surface cage plate 34,
Left side cage plate 31 and right side cage plate 32 distinguish split in the both sides of middle surface cover plate 33, and the split of bottom surface cage plate 34 is in middle surface cover plate 33
Bottom,
The shape of middle surface cover plate 33 is formed by connecting by top 331, base 332, lower-left side 333 and bottom right side 334
Axisymmetric closed figure, wherein:Top 331 is that with the trapezoidal of circular sliding slopes transition, base 332 is straightway, top 331
Two bottoms connect the top of lower-left side 333 and the top of bottom right side 334, lower-left side 333 and bottom right side respectively
334 is all the circular arc being convex to inside top 331, and the two ends on base 332 connect respectively the bottom and bottom right side of lower-left side 333
334 bottom,
The shape of left side cage plate 31 is formed by connecting by upper hypotenuse 311, bottom straight flange 312, left side 313 and right edge 314
Closed figure, wherein:The lower-left side 333 of upper hypotenuse 311 and middle surface cover plate 33 matches each other, left side 313 and middle surface cover
Spliced in the mode of smoothly transitting the left bottom of the top 331 of plate 33;The shape and left side cage plate 32 of right side cage plate 32 is axisymmetricly(I.e.
Right side cage plate 32 is the mirror image of left side cage plate 31);The top margin of bottom surface cage plate 34, left side and right side respectively with the bottom of middle surface cover plate 33
The left side split on side, the right edge of left side cage plate 31 and right side cage plate 32;
An oblique angle as shown in figure 3, bottom of the lower-left side 333 of middle surface cover plate 33 is pruned, the oblique angle is from lower-left side 333
A little inclining to the inner side on the base 332 of middle surface cover plate 33 on bottom, as shown in two, lower left corner dotted line in Fig. 3, the oblique angle
Vertical height be not more than 30mm, the horizontal width at the oblique angle is not more than 3mm;
The bottom of the bottom right side 334 of middle surface cover plate 33 is pruned an oblique angle, the oblique angle from the bottom of bottom right side 334 one
Point to the inner side on the base 332 of middle surface cover plate 33 inclines, and the vertical height at the oblique angle is not more than 30mm, the level width at the oblique angle
Degree is not more than 3mm;
The left side and right side on the base 332 of middle surface cover plate 33 is respectively pruned an oblique angle, and the oblique angle in left side is from the left bottom of base 332
On some lower tilt of lower side 333 to the left, some lower side to the right of the oblique angle on right side from the bottom right side of base 332
334 lower tilt, the vertical height at the oblique angle is all not more than 30mm, and the horizontal width at the oblique angle is all not more than 3mm;
Surface cover 4 left side set 41, right side set 42, middle surface cover 43 and bottom surface set 44 as shown in figure 4, be made up of, the left side set 41, right side
