Description

DETAILED DESCRIPTION OF THE INVENTION "Industrial application field" The present invention relates to a molded ceiling for an automobile, in which a surface of a ceiling base material on the vehicle interior side is divided into two or more regions.

“Prior Art” Conventional molded ceilings for automobiles include, for example, those shown in FIGS. 9 to 11.

That is, the molded ceiling 1 is composed of a front roof 2 and a rear roof 3, one skin 5 is attached to the vehicle interior side surface of the base material 4 of the front roof 2, and the base material 6 of the rear roof 3 is attached. An outer skin 7 of a different type from the outer skin 5 is attached to the surface of the passenger compartment side of the vehicle. A step portion 8 is formed at the front end portion of the rear roof 3, and the rear end portion of the front roof 2 and the step portion 8 of the rear roof 3 are overlapped with each other so that the outer skins 5 and 7 are smoothly connected. ,
It is fixed to the connecting bracket 9 so that it cannot be separated.

As a result, the molded ceiling 1 is divided into two types of skins 5, 7.
It can give a high-class feeling.

"Problems to be solved by the invention" However, in such a conventional molded ceiling for an automobile, the front roof 2 and the rear roof 3 are separate parts,
Since it is assembled by the connecting bracket 9, the number of parts is large, the number of assembling steps is large, and the cost is high. Moreover, depending on the accuracy of each part and the assembling accuracy, a gap is formed at the joint between the skins 5 and 7. However, there is a problem in that the joints cannot be treated cleanly due to the occurrence of a gap or a step, which impairs the aesthetics and increases the cost for a clean treatment.

The present invention has been made in view of the above-mentioned conventional problems. The number of parts is reduced, assembly work is improved, cost is not increased, and the interior surface of the passenger compartment is formed. It is an object of the present invention to provide a molded ceiling for an automobile that can cleanly treat a joint between different types of areas and improve aesthetics.

[Means for Solving the Problems] The gist of the present invention for achieving such an object is to provide a molded ceiling for an automobile in which the surface of the ceiling base material on the vehicle interior side is divided into two or more regions. In, the two or more kinds of areas are arranged on the surface of the ceiling base material on the vehicle interior side, and the portion of the ceiling base material corresponding to the boundary line between the adjacent areas is a thin-walled boundary part. Is a thin line parallel line part corresponding to the parallel lines that are parallel to each other with a constant distance from the boundary line, and the thin line boundary part is in the direction opposite to the passenger compartment side. In the molded ceiling for an automobile, the thin parallel line portions are bent and joined so as not to be separated from each other so that the adjacent regions are smoothly continuous with each other while protruding.

[Operation] Two or more types of regions are arranged on the surface of one ceiling base material on the vehicle interior side, and thin-walled boundary line portions and thin-walled parallel line portions are formed by, for example, a molding die. As a result, an error such as a relative position between the thin-walled boundary line portion and the thin-walled parallel line portion becomes extremely small.

Next, the thin-walled boundary line portion is projected in the direction opposite to the passenger compartment side, and the thin-walled parallel line portion is bent, so that the base material corresponding to each bent portion becomes thin-walled. It can be bent easily and with extremely high precision, and adjacent areas can be smoothly connected without any gaps or steps. Furthermore, by joining the thin parallel line portions so that they cannot be separated from each other, it is possible to maintain a state in which adjacent regions are smoothly continuous.

[Examples] Various examples of the present invention will be described below with reference to the drawings. In the various embodiments, the same parts are designated by the same reference numerals, and the duplicated description will be omitted.

As shown in FIGS. 1 and 2, a molded ceiling 1 for automobiles.
0 indicates that the surface 21 on the vehicle interior side of the base material 20 for the ceiling is divided into front and rear by the skins 30 and 30a which are two types of regions. A pad material 40 is interposed between the ceiling base material 20 and the skins 30 and 30a.

Cardboard, polyethylene foam, polyurethane foam, or the like is used as the material of the base material 20 for the ceiling.
A dark-colored vinyl chloride film and a light-colored non-woven fabric are used as the materials of 0 and 30a, respectively, and urethane foam or the like is used as the material of the pad material 40.

As shown in FIG. 5, the molded ceiling 10 for an automobile has a skin 3
0, 30a and the pad material 40 are laminated, the laminated material and the base material 20 for the ceiling are overlapped, and each material is pressed from above and below with a mold. Each material before pressing is in a substantially flat state, and two kinds of front and rear skins 30 and 30a are arranged on the front surface 21 of the ceiling base material 20 on the vehicle interior side with a gap between them. ing. Two kinds of epidermis 30, 30a
The gap between them forms the boundary. As shown in FIG. 4, each material after being pressed has a ceiling base material 2 corresponding to a boundary line.
The portion of 0 corresponds to the thin-walled boundary line portion 22, and the portion of the ceiling base material 20 corresponding to the parallel lines parallel to each other with a constant distance from the boundary line around the boundary line is the thin-walled parallel line portion 23. , 24. The skins 30 and 30a and the pad material 40 are those whose plate thickness hardly changes by pressing.

The plate thickness of the thin boundary line portion 22 and the thin parallel line portion 23 is almost half of the plate thickness of the general cross section of the ceiling base material 20, but it depends on the material of the ceiling base material 20. The degree of thinning may be adjusted.

As shown in FIG. 1 and FIG. 4, the storage recess 1 for the sun visor is formed at the front end of the automobile molded ceiling 10 when pressed.
1, a storage hole 12 for an interior light and the like are generally formed.

As shown in FIGS. 1 and 2, a molded ceiling 1 for automobiles.
After pressing, 0 further projects the thin-walled boundary line portion 22 in the direction opposite to the passenger compartment side, and the thin-walled parallel line portion 2
3, 24 are bent substantially at right angles and fixed to each other by caulking metal fittings 50 as shown in FIG. 3 so that they cannot be separated from each other. Not only the caulking metal fitting 50 but also a stitcher may be used for fastening.

Next, the operation will be described.

In FIG. 4, the skins 30 and 30a are arranged at predetermined positions on the surface 21 of the ceiling base material 20 on the vehicle interior side with the ceiling base material 20 as a reference, and the ceiling base material 20 is placed on the molding die. By setting and pressing, the error in the relative position between the thin-walled boundary line portion 22 and the thin-walled parallel line portions 23 and 24 becomes extremely small.
