Description

[Detailed Description of the Invention] The present invention relates to a mounting structure for a roof trim attached to the inner surface of a roof panel of an automobile, and particularly relates to a mounting structure for front and rear end portions of the roof trim.

A headlining made of resin sheets, knitted fabrics, etc. is usually hung from retaining wires on the inside surface of the roof panel of a car, that is, the side surface of the passenger compartment, to decorate the roof surface on the inside of the passenger compartment. In place of such headlinings, roof trims based on hardboard or, for example, corrugated cardboard with a liner bonded to a corrugated core through a thermoplastic resin coating, are being used. It is attracting particular attention because it is lightweight, relatively easy to process, and inexpensive.

By the way, when installing such a board-shaped roof trim, it is basically installed together with functional parts such as sun visor brackets, rearview mirror brackets, and room lamps, together with front roof rails and reinforcements installed in the center of the roof panel. It is tightened and the periphery is concealed with a decorative member as appropriate.

When installing the peripheral edge of the roof trim, normally the left and right ends can be easily concealed with a welt fitted to the edge of the vehicle body opening where the door is attached, but the front and rear ends are hidden behind the vehicle body roof. Due to the structure of the front and rear parts, it must be hidden with a special garnish.

As illustrated in FIG. 2, a front roof rail 2 and a rear roof rail 3 are provided at the front and rear of the roof panel 1, and a weather strip is attached to the joint flange between the roof panel 1 and the roof rails 2 and 3. 4
A structure is adopted in which the weather strip 4 supports the front windshield 5 or the rear windshield 6 by fitting the weather strip 4. Therefore, the front and rear end portions 7'a of the roof trim 7' are attached to the front and rear portions of the roof. Since there are no functional parts that can hide the roof trim end part as shown in the diagram? A structure is adopted in which the garnish 8 is applied across the mounting base of the weather strip 4 and the weather strip 4, and is fastened together to the roof rails 2 and 3 with screws 9.

However, how can the garnish 8 be used from the mounting base of the weather strip 4 to the end of the roof trim? If the garnish 8 is to be hidden over the roof trim 7'a, it is necessary to make the garnish 8 relatively wide, and even if the garnish 8 is colored in the same color as the roof trim 7', there will be no sense of continuity. , there was a regret that it spoiled the interior appearance of the vehicle.

In view of the conventional situation, this proposal adopts a lightweight and inexpensive corrugated cardboard roof trim as a roof trim, and crushes the front and rear ends of the roof trim into a single-layer board shape to form a vehicle roof rail corresponding to the trim end. By firmly clamping and holding the weather strip with the base of the weather strip, it is possible to improve assembly workability and the appearance of the vehicle interior, and also to eliminate the need for a garnish to obtain an inexpensive mounting structure with good workability.

An embodiment of the present invention will be described below with reference to the drawings, in which the same parts as those of the conventional structure are denoted by the same reference numerals.

In FIG. 3, 7 is a board-shaped roof trim, and the roof trim 7 includes a corrugated cardboard base material 10 and a corrugated cardboard base material 1.
A skin material 14 is integrally thermoformed on one side of the 0.

The corrugated board base material consists of a corrugated core 11 and liners 12 pasted on both sides of the core 11. The core 11 and liners 12 are pasted together using a hot melt sheet 13 made of polyethylene film or the like. This is done by gluing.

In other words, this corrugated cardboard base material 10 is processed using a predetermined heat press machine (
(not shown), the hot melt sheet 13 is melted by heating, pressurizing, and thermoforming to match the shape of the interior surface of the vehicle interior of the vehicle body roof panel 1, and after being released from the mold, the hot melt sheet 13 is solidified. The skin material 14 is polymerized onto the corrugated cardboard base material 10 via a hot melt sheet 15 similar to that described above, and the hot melt sheet 15 is melted at the same time as the corrugated cardboard base material 10 is thermoformed. , the corrugated cardboard base material 10 is pasted by solidification, or the skin material 14 is pasted after the corrugated cardboard base material 10 is thermoformed.

The front and rear end portions 7a of the roof trim 7 are pressurized more strongly than the general portions to form a single-layer board shape, that is, the corrugated core 11 of the corrugated cardboard base material 10 is almost completely crushed. 11 and both side liners 12 are brought into close contact with each other via a hot melt sheet 13 to increase rigidity, and the tip 7b is bent upward.

On the other hand, there is a space between the mounting base of the weather strip 4 corresponding to the front and rear ends 7a of the roof trim 7 and the front and rear roof rails 2, 3, which is slightly narrower than the thickness of the bent tip 7b of the roof trim 7. A groove 20 is formed.

For example, this groove 20 is connected to the weather strip 4 as shown in the figure.
In addition to cutting out the mounting base of the roof rails 2 and 3,
It may be formed with a concave side.

Then, the bent tip 7b of the roof trim 7 is inserted into this groove 20.
is inserted, and the bending tip 7b is held between the mounting base of the roof trim 4 and the roof rails 2 and 3 by the elasticity of the weather strip 4.

According to this embodiment, when attaching the front and rear end portions 7a of the roof trim, the conventional garnish 8 is not required, and the trim tip 7b is simply attached to the groove 20 between the attachment base of the weather strip 4 and the roof rail 2°3. Because it only needs to be inserted into the vehicle, installation work efficiency can be significantly improved, and the interior appearance of the vehicle can be further improved.

Moreover, since the roof trim 7 is made of cardboard base material 10, which is lightweight, relatively easy to process, and inexpensive in terms of material, and as mentioned above, the garnish 8 is not required, reducing the number of parts. This makes it possible to reduce costs.

Furthermore, since the front and rear end portions 7a of the roof trim are crushed into a single-layer board shape to increase rigidity, there is no sagging peculiar to corrugated cardboard, which not only facilitates insertion into the groove 20 but also prevents wrinkles. This is very advantageous in terms of appearance.

Moreover, the trim tip 7b is bent to maintain its shape, and this tip 7b is bent to maintain its shape.
Since the end portion b is firmly sandwiched within the groove 20, the end portion will not come out due to vibrations of the vehicle body, and the front and rear end portions of the roof trim can be reliably attached.

It goes without saying that the present invention can also be applied to roof trims made of ordinary hardboard.

In summary, according to the present invention, when attaching the front and rear ends of a corrugated roof trim, the ends are crushed into a single-layer board shape to increase rigidity, and the ends are inserted into the groove between the weatherstrip base and the vehicle roof rail. Since it is made of solid wood, work can be done smoothly and easily, and the roof trim can be reliably attached without the bumps peculiar to corrugated cardboard at the front and rear ends of the roof trim, and there is no wrinkles.

In addition, there is no need to use a wide garnish for concealment as is commonly done in the past, and the tip of the trim extends to the joint between the weather strip and the vehicle roof rail and is stored in the groove in that area. As a result, the terminal is completely hidden, thereby significantly improving the interior appearance of the vehicle.
