DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. Note that the members, arrangement, etc. described below do not limit the present invention, and can be variously modified within the scope of the spirit of the present invention.

1 to 4 illustrate the present invention,
The vehicle roof lining S equipped with curtain rails of this example is equipped with a sunroof Sf for the front seats and a sunroof Sr for the rear seats, as shown in FIG. It is equipped with rails L and L. In order to attach the curtain rail L to the roof lining S, which is equipped with such a sunroof Sf for the front seats and a sunroof Sr for the rear seats, the strength of the roof lining itself must be increased because the sunroof occupies a large area. It is necessary to prevent this from decreasing, and if the curtain rail L is attached as is, the attachment strength will decrease, but in this example, the curtain rail itself is used for reinforcement. Note that a known curtain rail L is used.

That is, as shown in FIG. 2, the roof lining S of this example includes a surface material 11 made of woven fabric or non-woven fabric, and a urethane base material, a glass wool base material, a resin felt base material, a honeycomb base material. A lining base material 12 consisting of, etc., a curtain rail L, a predetermined position of this curtain rail L,
That is, a thermosetting reinforcing sheet 13 made of SMC (sheet molding compound), prepreg, epoxy resin, phenol resin, etc., disposed at the mounting position with the vehicle body side B is laminated, and furthermore, the vehicle body side mounting member 14 is integrated. It is formed by compression molding using a press mold, and the roof lining S and curtain rail L are attached to the vehicle body side B using the attachment member 14. The mounting member 14 is
One end is fixed to the bottom of the curtain rail L, and the other end is formed with an engagement part 14a with the vehicle body side B.

At this time, a harness cord attachment hook 15 is provided on the attachment member 14 at a location spaced apart from the attachment position of the attachment member 14, and the attachment member 14 and the vehicle body side B are attached. The harness cord attachment hook 15 is made of a thin metal plate or resin that can be easily deformed. By doing this, after installing the roof lining S and the curtain rail L, the harness cord 16
can be easily attached by bending the harness cord attachment hook 15 in the direction of arrow X in FIG.

The manufacturing method of a vehicle roof lining equipped with the curtain rail L having the above structure is as follows. That is,
As shown in FIG. 4, a compression molding mold 20 consisting of an upper mold 21 and a lower mold 22 each having a cavity having a predetermined roof lining shape is used. A recess 23 is formed in the lower mold 22 at a predetermined position, that is, at a position where the vehicle body mounting member 14 of the curtain rail L is arranged, in which the engaging portion 14a of the mounting member 14 can be accommodated so as not to be crushed during molding. Recess 2
The thermosetting reinforcing sheet 13 is placed in the area corresponding to position 3, and then the lining base material 12 and the surface material 1 are placed.
1 and 2 are sequentially stacked. At this time, by forming holes (not shown) in the surface material 11 for arranging the mounting members 14, the mold setting of the curtain rail L can be facilitated. Further, the vehicle body mounting member 14 is positioned at the position of the recess 23 of the lower mold 22. At this time, the opening of the curtain rail L is placed on the upper mold 21 side. Then, compression molding is performed by applying pressure with the upper die 21. In addition, although the surface material 11 and the lining base material 12 were made into separate bodies in the said Example, they may be laminated|stacked integrally beforehand.

With the above structure, the curtain rail L plays the role of clamping the surface portion of the roof lining base material 12, that is, the surface material 11 during compression molding, and by pressing the curtain rail L, the laminated The surface material 11 and roof lining base material 12 are compressed, and tension can be applied to prevent wrinkles from forming on the surface material 11 due to compression molding. It is particularly effective in preventing molding wrinkles from forming in the drawing area.

[0015] By adjusting the size and position of the holes made in the surface material 11 described above, the manner in which tension is applied can be adjusted.

[0016]

[Effects of the Invention] Since the present invention is constructed as described above, there is no need to use reinforcing material over the entire area where the curtain rail is attached as in the past, and the roof lining and curtain rail can be attached at the same time. It is possible to provide a manufacturing method for a roof lining for a vehicle equipped with a curtain rail that requires a small number of manufacturing steps and can maintain installation strength. Furthermore, since the roof lining and the curtain rail are simultaneously molded during molding, the surface material is given tension by the curtain rail, which prevents molding wrinkles from occurring at the drawn portion, resulting in a good yield. Further, by attaching the curtain rail to the vehicle body using a vehicle body attaching member of the curtain rail and disposing a harness cord attaching hook on the vehicle body attaching member, conventional post-processing can be made unnecessary.
