ことができない。Background technology Usually, skin material 1, wading material 2, lining material 3
When forming a trim cover T with an uneven pattern P formed on the surface by integrally joining them together, when the three parts are simply overlapped and sewn or welded, the elongation rate of the skin material 1 (see Figure 1) is Or, due to the influence of tensile strength, etc., the wading material 2 escapes to the back side so as to bulge the backing material 3, making it impossible to maintain the roughness of the uneven pattern that appears on the front side, and making the uneven pattern unclear. It cannot be avoided. For example, if a skin material with an elongation rate of 100 to 150% is used, the effect will only be 50 to 70%, and even if it can be expanded to a somewhat satisfactory level, the skin material will sag or wrinkle. Resulting in. This is noticeable in the case of skin materials that are commonly used and have an elongation rate of 0 to 50%, and in this case, the effect can only be achieved by about 20 to 40%.

掛ることを余儀なくされる。 On the other hand, conventionally, in order to form a trim cover with a large uneven pattern, the convex parts of the uneven pattern are pushed up from the back side with a protruding blade so as to correspond to the contour, and the backing material 3 is press-fitted inside. The back side of the trim cover is curved upward to maintain its shape (see Figure 2), and the back side of the trim cover is molded to form a multi-mounted pad f 1 (see Figure 3) or an individual chevron-shaped pad (see Figure 3). shape-retaining members f 2 , f 3 (fourth
(see figure). However, in any of these cases, the thickness of the wading material cannot be fully utilized because the three materials are laminated and joined together by pressure using a mold or welder mold, and voids are created inside or on the mating surfaces. Wrinkles and deformation are likely to occur due to movement during seating, especially in the latter case (see Figures 3 and 4), which not only results in a loss of softness but also increases costs, and the shape-retaining member f 1 , f 2 , and f 3 are unavoidably time-consuming.

り合せ或いは熱融着するようにできる。 The surface material 10 has a seat plane W 1 of a bucket sheet.
Use a mold with a sufficient area to cover the left and right grips W 2 and W 3 (Fig. 7), and insert it into a mold (Fig. 8).
A concavo-convex pattern P is formed in advance on the seat plane W 1 (see figure), and the mold is clamped so as to bulge the part D that covers the edge part. This mold consists of upper mold C 1 and lower mold C 2
A movable mold 20 is attached to the upper mold C 1 so as to be movable up and down, and cavity surfaces 21 for bulging molding are provided at positions corresponding to the left and right edges. In addition, the lower mold C 2 has a surface material 1 between the cavity surface 21 and the protruding blade mold 22 corresponding to the uneven pattern.
A blade die 23 for holding the 0 is provided. In this mold, after lowering the movable mold 20 from the upper mold C 1 and adjusting the height between it and the lower mold C 2 , the skin material 10 is first lowered into the upper mold with the left and right sides supported by the clamps 25 .
Apply pressure by lowering the whole body of C 1 to create an uneven pattern. Along with the shaping, the left and right sides D of the skin material 10 can be continuously bulged into a shape corresponding to the edge portions W 2 and W 3 . In shaping this skin material, the movable mold 20 is made of a porous material, or a large number of through holes are formed in it to supply steam to the shaping surface (see Fig. 10), or the lower mold C 2 is filled with plaster 26 and heated and supplied with water vapor so that it can scatter (first
(see Figure 1), the shaping can be facilitated. After shaping the skin material 10, a wadding material 11 which remains substantially flat and has a thickness corresponding to the depth of the convex portion is fitted and fixed into the convex portion of the concavo-convex pattern. This wadding material 11 is coated with either acrylic emulsion or urethane-based emulsion type adhesive, solvent type adhesive, reactive adhesive, heat fusion adhesive, etc., and is fitted into the convex part. The upper mold in a flat state with the movable mold 20 retreated from the
By pressing with C 1 , it can be formed integrally with the skin material 10 (see FIG. 9). By overlaying the wading material 11 and directly joining the lining material 12 to the inner surface of the recess of the skin material 10, the lining material 12
are kept flat and the convex parts of the skin material 10 are kept in shape with the wading material 11 to form the three parts in one piece, and this backing material 12 is bonded with an adhesive or heat-sealed to the inner surface of the concave part of the skin material 10. You can do it like this.

ようにすることもできる。 In the trim cover manufactured in this way, when drawing and forming the skin material 10 in advance, a desired large uneven pattern can be formed, and the edges of the protrusions can also be sharply shaped, and a predetermined thickness can be formed inside the protrusions. By fitting and fixing the wading material 11 formed flat, it is possible to make the shape by making use of the entire thickness of the wading material 11, and the backing material 12 also has a recess in the skin material 10 where the wading material 11 is fitted and the surfaces are aligned. Since it is joined to the cushion body F, the back surface side can be formed flat, making alignment with the cushion body F easy. In addition, the lines D corresponding to the left and right edges are sharp to form the shape when drawing the skin material 10 without intervening wading material, and they are integrally molded to be continuous with the plane of the seat. become able to. Note that the skin material 10 can be made to have air permeability by being treated with a heat press or the like when forming the uneven pattern, and the air permeability can enhance the restoring force of the uneven pattern. Furthermore, in view of the need for lighter and thinner skins, a thin skin material composited with a reinforcing material such as non-woven fabric or knitted fabric can be used on the back side.

The edges can be formed deep and at any desired thickness with sharp edges, and the back side can be formed flat to facilitate alignment with the cushion body and to simplify installation. Since the outer skin can be continuously molded into a predetermined shape, the molding process can be simplified and the effort required to attach the cover can be saved.
