Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a mounting structure for a ceiling lining material of an automobile.

(Prior art) Generally, it is difficult to adopt a single molded ceiling structure for automobile ceiling lining materials due to the size of the vehicle interior and the shape of the roof. In such cases, the ceiling lining material is A mounting structure is often adopted in which the vehicle is divided into two parts, and the ends of the divided parts are overlapped with each other and attached to the roof panel on the body side.

As a conventional example that adopted this kind of mounting structure,
For example, there is one described in Japanese Utility Model Application Publication No. 59-170067.

That is, in this conventional example, the ceiling lining material is divided into two parts in the longitudinal direction of the vehicle body at the reinforcement part at the bottom of the roof panel, and the ends of the divided parts are overlapped with each other, and the overlapping part is fixed with screws or the like. It is configured to be integrally fixed to the roof panel by screwing the reinforcement into the reinforcement with a screw member.

(Problem to be solved by the invention) However, in the conventional structure described above, the head of the screw member for screwing is exposed at the overlapping part after the ceiling lining material is installed, resulting in a very poor appearance. becomes. Further, since it is necessary to screw a plurality of screw members in the vehicle width direction, there is a problem that the installation work is also relatively labor-intensive.

(Means for Solving the Problems) The present invention was made with the aim of solving the above problems, and includes a roof panel equipped with a rain reinforcement on the lower surface, a roof panel provided at the bottom of the roof panel, The ceiling lining material is divided into front and back parts at the reinforcement part, the upper end is locked to the reinforcement, and one end of the divided part of the ceiling lining material is fitted into the first fitting part on the lower side. while the second one on the upper side is fixed in the opposite direction.
and a stiffener having a substantially S-shaped cross section, into which the other end of the divided portion of the ceiling lining material is fitted.

(Function) According to the above means, the stiffener, which is locked to the reinforcement at the lower part of the roof panel, is first attached to one of the ceiling lining materials divided in the longitudinal direction of the vehicle body using the first fitting part on the lower side. After fitting and fixing the side split end, and locking the upper end to the reinforcement in the fixed state, the other side split end is fitted and inserted into the second fitting part on the upper side, thereby forming the ceiling lining material. Since it can be fixed, the installation work becomes easy, and there is no need to expose special locking means such as screw members, which further improves the appearance.

(Example) FIGS. 1 and 2 show an automobile ceiling lining material mounting structure according to an example of the present invention.

First, in FIG. 1, reference numeral 1 denotes a roof panel of an automobile body, and a reinforcement 2 having a substantially U-shaped cross section extending in the vehicle width direction is provided on the lower surface of the roof panel 1 to reinforce the roof panel 1.
are integrally welded and fixed. As shown in FIG. 2, the reinforcement 2 has a plurality of engagement holes 4, 4, .

Reference numeral 6 is a stiffener, and the stiffener 6 has a cross section of approximately S having a predetermined bending elasticity.
It is formed from a letter-shaped thin plate metal member,
The reinforcement 2 is attached to the upper edge 6a.
A plurality of locking pieces 7, 7... that engage in a hook-like manner with the plurality of engagement openings 4, 4... are provided, while a plurality of locking pieces 7, 7... are provided in each of the U-shaped openings on the lower and upper sides of the ceiling lining material. First and second fitting portions 9 and 10 are formed for fitting each divided end portion lightly. The first and second fitting parts 9 and 10 are formed such that the opening diameter of the first fitting part 9 is smaller than that of the second fitting part 10.

On the other hand, reference numeral 12 is a ceiling lining material provided at the lower part of the roof panel 1, and this ceiling lining material 12 is divided into two parts in the longitudinal direction of the vehicle body at the reinforcement 2 portion. The front side ceiling lining material 12a and the rear side ceiling lining material 12b formed by the division are as follows:
the first and second fitting portions 9 of the stiffener 6 that are locked to the reinforcement 2;
By fitting or inserting each split end side into the roof panel 10 in abutting state as shown in the figure, the whole can be integrally attached to the roof panel 1. Above rear side ceiling lining material 1
The divided end portion of 2b is bent upward to form a stepped portion for abutment. The above installation is then performed in the following order.

That is, first, the first fitting part 9 of the stiffener 6 is deformed to some extent in the opening direction using its elastic force, and thereby fitted to the split end of the front side ceiling lining material 12a. By attaching the stiffener 6 to the front ceiling lining material 12a in a fixed state, and then engaging the locking pieces 7, 7... with the engagement ports 4, 4... of the reinforcement 2, respectively, the rain The stiffener 6 is locked to the reinforcement 2, and the front ceiling lining material 12a is temporarily locked.

Next, in this state, the divided end of the rear ceiling lining material 12b is fitted into the upper second fitting part 10 of the stiffener 6 and locked therein. This completes the entire installation of the ceiling lining material 12.

Therefore, according to the above-mentioned structure, there is no need to use screw members at all, so not only does the appearance of the ceiling after installation become very good, but also the work of installing the reinforcement 2 itself becomes extremely easy. Furthermore, the ease of installation is not only a matter of the front and rear joints, but also the front and rear ceiling lining materials 12a, 12b.
As described above, each of the ceiling lining materials 12 can be fixed once at the center of the vehicle interior and then attached to the roof rail at the peripheral edge, making the installation work of the ceiling lining material 12 as a whole considerably easier.

(Effects of the invention) As explained above, the present invention consists of a roof panel with a reinforcement on the lower surface, and a ceiling lining material provided at the bottom of the roof panel and divided into front and rear parts by the reinforcement part. and,
The upper end is locked to the reinforcement, and one end of the divided part of the ceiling lining material is fitted and fixed to the first fitting part on the lower side, while the second end on the upper side in the opposite direction is fixed to the first fitting part on the lower side. The fitting part is provided with a stiffener having a substantially S-shaped cross section into which the other end of the divided part of the ceiling lining material is fitted.

Therefore, according to the present invention, the stiffener, which is fixed to the reinforcement at the lower part of the roof panel, is first attached to one side of the ceiling lining material divided in the longitudinal direction of the vehicle body using the first fitting part on the lower side. After fitting and fixing the divided end and locking the upper end to the reinforcement in the fixed state, the upper second
The ceiling lining material can be fixed by fitting the other side split end into the fitting part of the ceiling lining, which simplifies the installation work, and also eliminates the need to expose special locking means such as screws, making it look even better. will improve.
