DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a molded ceiling for an automobile.

[0002]

2. Description of the Related Art As a ceiling provided on the inner surface of a roof 2 of a vehicle body 1 as shown in FIG. 4, a one-piece molded ceiling 3 formed into a predetermined shape has been used. FIG. 5 shows a partial structure of an automobile using such a molded ceiling as shown in FIG.
FIG. 2 is a schematic view of a cross section taken along line AA of FIG. The inner structure of the roof 2 has a roof panel 2a to which a roof rail 2b is fixed, and a windshield glass 5 attached to a front window portion via a weather strip 4. The outer peripheral portion on the inner surface side of the windshield glass 5 is subjected to a black coating process 6. And
The molded ceiling 3 is fixed to the roof rail 2b by locking means (not shown). In this case, in the front window portion, the end 3a of the molded ceiling 3 is located inside the black painted portion 6 of the windshield glass 5, and is arranged so as to be hidden from the outside of the vehicle body by the black painted portion 6. .

[0005] The molded ceiling 3 shown in FIG. 5 is formed by laminating a skin material 8 on a surface of a base material 7 made of corrugated cardboard or the like and integrally cutting the end portion of the base material 7 with the skin material 8. (End face cut structure), and these end faces 3a are opposed to the windshield glass 5 with a slight gap X therebetween. FIG. 6 shows another example of the structure of the molded ceiling. In the molded ceiling 3, at the end 3 a of the molded ceiling 3, the end portion 8 a of the skin material 8 is extended beyond the terminal of the base material 7, and the extended portion is folded back to the back surface side of the base material 7 and adhered. The end face of the base material 7 is concealed by a skin material 8 (skin material winding structure). In this case also, the end face 3a is opposed to the windshield glass 5 with a slight gap X therebetween. .

The reason for providing the gap X between the terminal 3a and the windshield glass 5 is that the end face 3a is designed to abut on the windshield glass 5 from the beginning.
Due to a manufacturing error or the like, the end 3a of the hard base material 7 collides with the windshield glass 5 at the time of assembling, and cannot be assembled at a fixed position. This is in order to prevent the occurrence of a ceiling, and the same is true for any of the molded ceilings 3.

[0005]

However, in the conventional structure in which the gap X is provided from the beginning as described above, the gap X varies due to a manufacturing error. And this gap X
Is formed too large, there is a problem that the end faces of the skin material 8 and the base material 7 can be seen from outside and inside the vehicle, and the appearance is deteriorated.

Further, in the case of the end face cut structure illustrated in FIG. 5, there is no work of winding the end portion of the skin material into the skin material winding structure illustrated in FIG. Since the end face can be seen from the inside, cutting accuracy is required and appearance is likely to be deteriorated. In addition, in the skin material winding structure, the work of winding the terminal portion of the skin material with respect to the base material terminal is generally performed manually, so the workability is poor, and the work environment is poor because an adhesive or the like is used. Has become.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and an object of the present invention is to improve the appearance of an end portion of a molded ceiling with a simple structure, and to structurally absorb manufacturing errors and the like. An object of the present invention is to provide a molded ceiling for an automobile as described above. Further, other objects will be clarified sequentially in the contents described below.

[0008]

The object of the present invention is to provide an essential part of the present invention, wherein a skin material is integrally adhered to the surface of a base material .
Both are formed in a ceiling shape and attached to the roof panel
In automobile formed ceiling, the formed ceiling, together with the surface material to the base material has integrally terminal extension protruding from the base terminal, said terminal extension tables that
It is projected on the extension of the base material end by the shape retention force of the skin material.
And attached to the roof panel,
The tip of the end extension portion by Rukoto placed close to the vehicle body panel inner surface is achieved. The above configuration is more effective when the distal end of the terminal extension portion approaches the inner surface of the windshield glass on the vehicle body panel side.

[0009]

According to the present invention, since the terminal extension of the skin material projects toward the vehicle body panel, the terminal of the base material cannot be seen at least from the indoor side. Further, when the gap X becomes small due to a manufacturing error or a mounting position error of the molded ceiling, the tip of the terminal extension portion of the skin material may come into contact with the vehicle body panel side (the inner surface of the windshield glass or the like). At this time, since the terminal extension portion has no base material, the terminal extension portion is easily bent, and the end of the terminal extension portion is always in contact with the vehicle body panel side. Also in this case, since only the relatively flexible end portion of the skin material hits the vehicle body panel side as compared with the conventional end face cut structure and the skin material winding structure, no abnormal noise due to friction is generated.

[0010]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows a main structure of a vehicle using a molded ceiling for a vehicle according to the present invention, and FIG. 2 is an enlarged view of a portion B in FIG. 1 and 2, the same reference numerals as those in FIGS. 5 and 6 denote the same members or parts, and FIG. 1 shows a portion of the automobile shown in FIG. 4 (a line AA in FIG. 4). Along the line)).

1 and 2, a roof 2 has a roof rail 2b fixed to a roof panel 2a, and a windshield glass 5 is mounted on a front window portion via a weather strip 4. This is the same as the conventional structure in that the outer peripheral portion on the inner surface side of the windshield glass 5 is coated with a black coating 6. Also, the molded ceiling 3 has a roof rail 2b inside the roof 2.
In the front window portion, the end of the molded ceiling 3 is located inside the black-painted portion 6 of the windshield glass 5, and the black-painted portion 6 is used to secure the vehicle from outside the vehicle body. The point of being arranged in a hidden state is the same as before. The major difference between the main structure of the present invention and the conventional structure is mainly found in the terminal portion of the molded ceiling. This structure will be described in detail below.

Here, the molded ceiling 3 is formed integrally by laminating a skin material 8 made of a nonwoven fabric or the like on the surface of a base material 7, heating and pressing. In addition, the terminal portion facing the windshield glass 5 is not cut without aligning the base material 7 and the skin material 8, and the terminal extension portion 9 protruding from the end portion 7 a of the base material 7 is provided at the end portion of the skin material 8. Has formed.

FIG. 3 shows an example of a forming process for forming a terminal extension 9 protruding from the end 7a of the base material 7 at the terminal of the skin material 8 in the above-mentioned molded ceiling 3.
Then, the molding process will be outlined with reference to FIG.

In the step (a), a sheet-like material of the base material 7 is arranged between the upper mold 10A and the lower mold 10B which are heated and pressed together, and this is heated by the upper mold 10A and the lower mold 10B. -At the same time as pressing to form a desired ceiling shape, unnecessary portions 7B are cut and removed. The base material 7 is a material such as a cardboard or a resin.

In the step (b), the molded base material 7 is taken out from the upper and lower molds 10A and 10B, and set in another molding mold (the same upper mold 10A and lower mold 10B may be used). Then, a sheet-like material for the skin material 8 is set on the surface of the base material 7 with an adhesive if necessary, and the base material 7 and the skin material 8 are set.
It is shown in a state of being integrated with a material for heating by heating and pressing. In this case, as the material of the skin material 8, a material having an area larger than that of the base material 7 is used, and is formed so as to obtain a portion 8B protruding outside from the terminal 7a of the base material 7.

The material of the skin material 8 may be a simple material such as nonwoven fabric or PVC foam, or a material in which a backing material such as urethane is integrally provided on various sheet materials. In short, what is necessary is just to have moderate shape retention.

In the step (c), the base material 7 with the skin material 8 integrated in the step (b) is set in another molding die, and the end 7a of the base material 7 is attached to the end of the skin material 8. Leaving the protruding terminal extension portion 9, another unnecessary portion 8 B is cut by the cutter 12.
Cut and remove with. Then, the step (d) shows a state in which the molded ceiling 3 which is a finished product obtained by cutting the unnecessary portion 8B, which is integrated in the step (c), is taken out.

The thus formed molded ceiling 3 is shown in FIG.
The terminal extension portion 9 is extended on the extension line of the terminal 7a on the base material 7 by the shape retaining force (shape retention characteristic) of the skin material 8 as shown in FIG. It is attached in a state of touching the part located at. In this case, the gap created between the windshield glass 5 and the molded ceiling 3 is the terminal extension 9 of the skin material 8.
Therefore, it will be absorbed, and it will be possible to always attach in a state of being in close contact. Further, in this structure, only the terminal extension portion 9 of the skin material 8 is brought into contact with the windshield glass 5 and the end face of the base material 7 is not brought into contact, so that
A problem with the conventional structure, for example, the base material is larger than the design size due to manufacturing errors and the like.
This eliminates such a problem that it cannot be installed at a predetermined position due to collision. In addition, since only the relatively soft terminal extension 9 comes into contact with the windshield glass 5, there is no occurrence of abnormal noise even when the terminal is rubbed by running vibration or the like.

In the above embodiment, the case where the terminal extension 9 is brought into contact with the front windshield glass 5 has been described. A slight gap may be provided without intentionally abutting. Further, the portion on the vehicle body panel side is not limited to the front windshield glass 5 and may be a general panel-shaped one such as a rear windshield glass or a trim board.

[0020]

As described above, the molded ceiling for an automobile according to the present invention has the following useful effects. Since only the terminal extension of the skin material is projected toward the body panel side (windshield glass inner surface, etc.),
The terminal of the base material becomes structurally invisible from the indoor side, and the gap X can be designed to be small. This is because even when the gap X becomes smaller than the design value due to a manufacturing error or a mounting position error of the molded ceiling, since the terminal extension portion has no base material, it easily bends when contacting the vehicle body panel side. Because it can be absorbed. In such a case, since only the relatively flexible skin material terminal extension portion hits the vehicle body panel side with respect to the end face cut structure shown in FIG. 5 and the skin material winding structure shown in FIG. 6, abnormal noise due to rubbing is generated. Never do. In addition, the structure can be precisely relaxed and easy to manufacture with respect to the end face cut structure and the skin material winding structure, and there is no fear that the hard base material is buffered on the vehicle body panel side.
