Description

[Detailed Description of the Invention] This invention relates to the structure of a sliding roof for an automobile in which an opening in the roof panel is opened and closed by the sliding roof, and in particular to an improvement in the sealing structure when the sliding roof is fully closed.

Recently, in wagons and the like, as shown in Fig. 1, an opening is provided in a roof panel 1, and a slide roof 3 is slid back and forth using a guide rail 2 attached to the roof panel 1 to open and close the opening. Things that have been made to do this are gaining popularity.

By the way, the seal structure at the rear of the slide roof when the slide roof 3 is fully closed is as follows.
As shown in FIG. 2, a rubber weather strip 5 is fitted to the rear lower surface of the slide roof 3 and fitted to the mating surface 4a of the reinforcement 4 fixed to the rear edge 1a of the opening of the roof panel 1. is brought into contact with the slide roof 3 when it is fully closed, while a fixing plate 6 is welded and fixed to the joint between the other mating surface 4b of the reinforcement 4 and the roof panel 1. Hold the flocked type dust seal 7 on the weather strip 5.
A sealing structure is adopted in which the sealing surface 8 is brought into contact with a sealing surface 8 formed on the lower surface of the rearmost edge of the slide roof 3 at the rear of the slide roof 3.

However, in such a conventional seal structure,
There is a drawback that rust is likely to occur on the mating surface 9 of the roof panel 1 and fixing plate 6 due to rainwater brought in between the weather strip 5 and the dust seal 7.

Therefore, the present invention has developed a dust seal that prevents the occurrence of rust by omitting the fixing plate that causes rust, has better sealing performance than a flocked type dust seal, and is particularly effective in reliably preventing rainwater, etc. The company aims to provide the seal structure for the sliding roofs of automobiles that use the technology.

Hereinafter, the present invention will be described in more detail with reference to the illustrated embodiments.

As shown in FIG. 3, in the present invention, a mounting portion 10a consisting of a horizontal portion is provided on the lower surface 3a of the rearmost edge of the sliding roof 3 that opens and closes the opening of the roof panel 1.
and a lip portion 10b extending obliquely downward and rearward at an angle of, for example, about 60° with respect to the mounting portion 10a.
Rubber dust seal 10 integrally formed with
is fixed over the entire width of the slide roof 3 using clips 14 or the like.

On the other hand, on the roof panel 1 side, a reinforcement 12 is installed to form a sealing surface 11 that comes into close contact with the front side of the lip portion 10b of the dust seal 10 when the slide roof 3 is in the fully closed position (the position shown in the figure). The rear side fixing part is made to protrude upward with a chevron-shaped cross section to form a protrusion 13, and its front inclined surface 13a is connected to the rear edge side mating surface 12a of the reinforcement 12.
While fixing this from below as a mating surface with
The rear inclined surface 13b is used as a sealing surface 11 for the lip portion 10b of the dust seal 10.

In addition, in FIG. 3, numeral 5 is a weather strip similar to that shown in FIG.
2, and comes into contact with the rear lower surface of the slide roof 3 when the slide roof 3 is fully closed.

As mentioned above, in the present invention, the lip portion 1 of the dust seal 10 attached to the slide roof 3 is
0b and is formed to be inclined rearward by a protrusion 13 provided on the roof panel 1, and the lip portion 1
Since the seal structure is formed by the sealing surface 11 that contacts the front surface of the seal lip 11b, the sealing lip 11b is further pressed by the sealing surface 11 due to the intrusion pressure of rainwater, etc., and the intrusion of rainwater etc. can be reliably prevented. In addition, since this sealing structure is used in conjunction with the weather strip 5 seal, the fixing plate 6 shown in FIG. 2 can be eliminated, rust can be prevented, and the dust seal Because it can be made of rubber, it has good adhesion, and the sealing effect can be greatly improved compared to conventional flocked dust seals, and it does not damage the paint film on the seal surface. Compared to a structure in which a type of dust seal is fixed with a fixing plate, it can be manufactured at a much lower cost and has the advantage of improving ease of assembly.

Claims (1)

[Scope of claim for utility model registration] Guide rails are installed on the roof panel along the front and both sides of the opening made in the roof panel, and a slide roof is provided that slides back and forth within the guide rails on both sides. In a sliding roof structure for an automobile in which an opening can be opened and closed by moving the sliding roof, a sealing member having a lip portion extending diagonally downward and rearward is attached to the rear lower surface of the sliding roof, and comes into contact with the front surface of the lip portion when the sliding roof is in the closed position. A seal structure for a sliding roof of an automobile, characterized in that a rearwardly inclined sealing surface is formed to protrude from a roof panel.
