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 integrally formed by superposing a skin material 8 on a surface of a base material 7 made of corrugated cardboard or the like. Cutting (end face cut structure) is performed, 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
That the automobile formed ceiling, the formed ceiling, together with the surface material to the base material is formed integrally with the terminal extension portion protruding from the base terminal, groups along the rear side of the terminal extension A state where the elastic piece is superimposed in a state of being extended from the material terminal and is attached to the roof panel
And the end of the terminal extension portion is attached to the vehicle body together with the elastic piece.
This is achieved by being disposed close to the inner surface of the windshield glass on the flannel side . Te above configuration smell, before SL terminal extension portion by being curved in the curled into molded ceiling backside, even like when you want to close to the vehicle body panel side, and easily absorb the dimensional tolerance at the curved portion You can approach without gaps.

[0009]

According to the present invention, 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 with the elastic piece is attached to the body panel side (the inner surface of the windshield glass or the like). ). In this case, the terminal extension portion is easily bent since an elastic piece is integrated instead of a hard base material, and the end of the terminal extension portion with the elastic piece is always in contact with the vehicle body panel side. Also in this case, since the relatively flexible skin material terminal extension and the elastic piece hit the vehicle body panel side, there is no generation of abnormal noise due to rubbing unlike the conventional end face cut structure or the skin material winding structure. . In particular, it is more preferable that the curved portion is formed in a curl shape, and the curved portion is brought into contact with the vehicle body panel side.

[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. An elastic piece 10 such as urethane or rubber is integrally formed on the back surface of the terminal extension portion 9 while being extended.

An example of the case of forming such a molded ceiling 3 will be outlined below. First, in the molding of the base material 7, the base material 7 is placed between the forming dies (upper and lower dies) which are heated and pressed together.
Is placed and heated and pressed to form a desired ceiling shape, while cutting unnecessary portions. In this cutting, of course, the terminal portion corresponding to the elastic piece 10 is also removed. The base material 7 is a material such as a cardboard or a resin. Next, it is a pressure bonding process of the skin material 8, and it is preferable that the elastic pieces 10 are simultaneously polymerized in this process. In this case, the shaped base material 7 is set in a molding die (which may be the above-described molding die), and is preliminarily placed along the base terminal where the elastic piece 10 is provided at the terminal portion of the base material 7. The prepared elastic piece 10 is also set. afterwards,
A sheet-like material for the skin material 8 is set on the surface of the base material 7 and the elastic piece 10 via an adhesive as necessary, and the base material 7, the elastic piece 10 and the material for the skin material 8 are heated and pressed. And integrate. In this case, the material of the skin material 8 is generally
An area larger than the area of the elastic piece 10 and the elastic piece 10 is used. After integration, unnecessary portions are cut to form a predetermined size. The material of the skin material 8 may be a soft material lacking in holding properties, such as cloth, or a non-woven fabric, a simple substance such as foamed PVC, or various sheet-like materials such as urethane as in the embodiment. The backing material 8a is provided integrally. The elastic piece 10 is made of a skin material 8.
Also has an action of imparting an appropriate shape-retaining property to the terminal extension portion 9.

The molded ceiling 3 created in this way is shown in FIG.
The terminal extension portion 9 is extended along the terminal extension line of the base material 7 by the shape retaining force of the elastic piece 10 together with the shape retaining force (shape retention characteristic) of the skin material 8, and the distal end side is wound on the windshield glass 5. Is attached in a state of contacting a portion located inside the black paint processing portion 6 of FIG. In this case, the gap generated between the windshield glass 5 and the molded ceiling 3 is absorbed by the terminal extension portion 9 with the elastic piece 10, and can be attached in a state of being always in close contact. Further, in this structure, the terminal extension 9 with the elastic piece 10 is brought into contact with the windshield glass 5 and the end face of the base 7 is not brought into contact with the windshield glass 5. Is larger than the design dimension due to a manufacturing error or the like, and the inconvenience such that the end portion of the hard base material 7 hits the windshield glass 5 and cannot be installed at a predetermined position when it is installed is eliminated. In addition, since the end surface of the terminal extension portion 9 with the relatively soft elastic piece 10 comes into contact with the windshield glass 5, there is no generation of abnormal noise even when the terminal is rubbed by running vibration or the like.

FIG. 3 is an example in which the above embodiment is modified, and the main part of the modified portion is shown in an enlarged manner. Note that FIG.
1 and 2 denote the same members or parts, and therefore, the description of FIG. 1 and FIG.
Only different modified parts will be described.

The molded ceiling 3 shown in FIG. 1 is integrally formed by laminating a skin material 8 made of a non-woven 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. The elastic piece 11 is integrally formed on the back surface of the terminal extension portion 9 while being extended. This elastic piece 11 is made of urethane, rubber, or the like,
It has a base 11a and a portion 11b which is curled or semi-circularly curved from the base 11a. After the base 11a is bonded to the back surface of the end 7a of the base member 7, the terminal extension 9 is bonded to and integrated with the outer surface of the portion 11b. And a curved portion 12 formed by a portion 11 b of the elastic piece 11 and the terminal extension 9.

In the molded ceiling 3 formed in this manner, the terminal extension 9 has the shape-retaining force (shape-retaining characteristic) of the skin material 8 and the shape-retaining force of the elastic piece 11 as well as the above-described embodiment. It is extended on a terminal extension line, and is attached in a state in which this tip side is in contact with a portion of the windshield glass 5 located inside the black painted portion 6. In this case, the gap generated between the windshield glass 5 and the molded ceiling 3 is absorbed by the terminal extension portion 9 with the elastic piece 11, so that it is possible to attach the windshield glass 5 in a state of being always in close contact. In this modification, the terminal extension portion 9 with the elastic piece 11 is brought into contact with the windshield glass 5 and the end face of the base material 7 is not brought into contact with the windshield glass 5. Due to a manufacturing error or the like, the dimension is larger than the design dimension, and when assembling, there is no problem that the end 7a of the hard base material 7 hits the windshield glass 5 and cannot be assembled at a predetermined position. In particular, terminal extension 9 with elastic piece 11
The curl-shaped curved portion 12 is advantageous in that it has an excellent gap absorbing effect and a good appearance from the indoor side. Moreover, windshield glass 5
Since the relatively soft curved surface portion of the curved portion 12 comes into contact with the contact portion, there is no generation of abnormal noise even if it is rubbed by running vibration or the like.

In the above embodiment, the elastic piece 10
Although the case where the terminal extension portion 9 or the curved portion 12 with the elastic piece 10 is brought into contact with the front windshield glass 5 has been described, the terminal extension portion 9 or the curved portion 12 with the elastic piece 10 can be replaced with the front windshield glass 5 or the like. A slight gap may be provided without intentionally contacting the vehicle body panel side. 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.

[0019]

As described above, the molded ceiling for an automobile according to the present invention has the following useful effects. When the end of the skin material terminal extension portion with the elastic piece protrudes toward the vehicle body panel side (the inner surface of the windshield glass, etc.), when the above gap X becomes smaller than the design value due to a manufacturing error or a mounting position error of the molded ceiling, etc. However, since the terminal extension portion has no base material, it can be easily bent and absorbed when abutting against the vehicle body panel side. Further, in such a case, the end portion of the skin material with an elastic piece having relatively high elasticity hits the vehicle body panel side with respect to the end face cut structure of FIG. 5 and the skin material winding structure of FIG. Will not occur. In addition, the elastic piece is superimposed in a state of extending from the base terminal along the back side of the terminal extension of the skin material, so careless even if the skin material has a small shape retention force like cloth, etc. Various materials can be used without sagging. It should be noted that the end face cut structure and the skin material winding structure can be relaxed with high precision, and there is no fear that the hard base material directly or indirectly buffers the vehicle body panel side. In addition, the appearance from the vehicle interior side can also be improved by making the shape of the skin material terminal extension portion with the elastic piece a curved portion.
