Further, the side edge side fixed portion 31 b is folded back from the side edge 14 of the wall portion 11 to the back side of the wall portion 11 .

At this time, the end portion of the side edge 14, which is the edge portion in the direction intersecting the direction in which the wall portion 11 protrudes from the base portion 10, is connected to the back side of the base portion 10, and the direction in which the wall portion 11 protrudes from the base portion 10 (Fig. 1 In the case of the conventional example formed along the arrow A in (a), the side edge fixing portion 31b is folded back in a direction perpendicular to the end portion thereof and overlapped on the back side of the wall portion 11. .

On the other hand, in the case of the present embodiment, at least a part of the wall-side fixed portion 31 with respect to the wall-covering portion 26, in the present embodiment, the folding direction of the side-side fixed portion 31b is arranged on the side edge 14. By providing the guide portion 35 that guides to the back side of the base portion 10 , the side edge side fixed portion 31 b can be overlapped with the back side of the base portion 10 instead of the back side of the wall portion 11 . Therefore, even in the case of the base material 3 in which it is not easy to obtain a sufficient fixing position on the back surface of the wall part 11, the fixing position (fixing point P) of the side edge fixing part 31b can be set on the back surface of the base part 10. Therefore, a position for fixing the skin 4 to the base material 3 can be secured. In particular, in the present embodiment, since the area of the base portion 10 is larger than the area of the wall portion 11, by setting the fixing position (fixing point P) of the side edge side fixing portion 31b to the back surface of the base portion 10, the surface body 4 to the base material 3 can be sufficiently secured.

Therefore, even in a limited and cramped layout, the fixing point P of the skin body 4 (side edge side fixing part 31b) to the base material 3 can be secured and firmly fixed. Therefore, it is possible to prevent the peeling of the skin body 4 from the base member 3 from the side edge side fixed portion 31b, that is, the terminal portion, and improve the productivity. In addition, since a constant tensile force can be generated when the side edge fixing portion 31b of the skin body 4 is folded back, the occurrence of wrinkles can be suppressed, and an improvement in appearance, that is, an improvement in appearance quality can be expected.

In addition, even if a welding tool is used when fixing the side edge fixing portion 31b to the base material 3, work space for the welding tool can be secured, and workability is good.

By forming the guide portion 35 as an inclined portion that is more inclined with respect to the projecting direction than the other portions at the side edge 14 that is the end edge in the direction intersecting the projecting direction of the wall portion 11 from the base portion 10 . , the guide portion 35 can be formed so that the folding direction of at least a portion of the wall-side fixing portion 31 (the side edge-side fixing portion 31b) can be easily controlled according to the inclination thereof.

The guiding portion 35 has a predetermined angle or a predetermined curvature with respect to the projecting direction of the wall portion 11 from the base portion 10 at the side edge 14 that is the edge portion in the direction intersecting the projecting direction of the wall portion 11 from the base portion 10 . , the folding direction of at least a portion of the wall-side fixed portion 31 (side-edge-side fixed portion 31b) can be reliably guided by the guiding portion 35. As shown in FIG.

By forming the guiding portion 35 linearly or curvedly, the guiding portion 35 can be easily formed on the side edge 14 which is the edge portion in the direction intersecting the direction in which the wall portion 11 protrudes from the base portion 10 .

Further, when forming the sewn portion 37 for design over at least the wall covering portion 26 to the wall portion-side fixed portion 31 of the skin 4, the strength (hardness) of the skin 4 is increased by the amount of the sewn portion 37 formed. Also, the difficulty of folding) is increased, and it is necessary to fix the skin body 4 to the base material 3 more firmly in order to suppress the return from the folded state. Therefore, in the present embodiment, since the fixing position of the skin body 4 to the base material 3 can be secured, the skin body 4 can be firmly fixed to the base material 3. Even with the skin body 4 in which the sewing part 37 is formed over the fixing part 31 , the skin body 4 can be made difficult to peel off from the terminal part to the base material 3 .

In addition, since the folding direction of the side edge fixed portion 31b is guided only by the shape of the guide portion 35, it can be applied to any interior material 1 having the skin body 4. FIG.

By adjusting the inclination angle α and the curvature of the guiding portion 35, the direction of folding back of at least a portion of the wall-side fixing portion 31 (the side-edge-side fixing portion 31b) can be controlled. Point P is adjustable. For example, as in the second embodiment shown in FIG. 4, by setting the angle α to be larger, the wall-side fixed portion 31 (side-edge-side fixed portion 31b) is folded back with respect to the wall covering portion 26. (indicated by arrow B) can be directed further away from wall 11 toward base 10 . That is, the angle α can be set according to the position where the fixing point P is desired to be set. For example, the fixation point P can be adjusted according to matching with other parts.

Further, the position of the guiding portion 35 is not limited to being formed continuously on the back surface of the base portion 10 , and may be set at any position between the tip edge 13 and the back surface of the base portion 10 on the side edge 14 . For example, as in the third embodiment shown in FIG. It may be formed as a non-inclined portion 40 along the projecting direction of the empty wall portion 11 .

Furthermore, in each of the above-described embodiments, the sewn portion 37 can also be formed on the skin 4 formed by stacking a plurality of skin pieces to increase the thickness.

The interior material 1 can be applied to any vehicle interior material other than interior materials such as a center console and an instrument panel. Moreover, it is applicable not only to vehicle interior materials but also to any other interior materials.

INDUSTRIAL APPLICABILITY The present invention can be suitably used, for example, as a vehicle interior material used for a center console or an instrument panel of an automobile.
