Description

[Detailed Description of the Invention] This invention provides a dirt prevention device for a sliding door car,
That is, the present invention relates to a dirt prevention device that prevents grease loaded in an upper guide rail from adhering to an occupant.

As is well known, in so-called sliding door vehicles such as van-type vehicles, the sliding door is guided by three guide rails: an upper guide rail, a center (waist) guide rail, and a lower guide rail. Among these, the upper guide rail installed on the roof side of the car body has its lower surface running along the longitudinal direction so that the arm connected to the sliding door can pass through. It's open. In the above-mentioned sliding door cars, the height of the sliding door frontage is generally much lower than the average height of an adult, so the top guide rail may come into contact with the head when getting on and off, and the rail There are problems such as the grease applied inside the vehicle getting on the hair and contaminating passengers getting on and off the vehicle, or getting your hands dirty with the grease when you put your hand on the roof side above the sliding door.

Therefore, in order to prevent such contamination due to grease, a contamination prevention device shown in FIG. 2 was previously proposed by the present applicant as U.S. Pat. No. 5,731,218. As shown in Figure 1, this is an example of a so-called center pillarless car with a hinge type front door and a sliding type rear door. A seal rubber 5 having a lip 5a protruding diagonally upward toward the opening 4 of the upper guide rail 3 is attached to the lower end of one side wall 3a of the fixed upper guide rail 3, thereby preventing heat. It covers the lower side of the opening 4 of the par guide rail 3. Here, the upper guide rail 3 has a U-shaped cross section with a pair of opposing side walls 3a and 3b having different lengths, and the longer side wall 3a is used as the mounting surface for the roof. The outer side 1a of the side rail 1, more specifically, the almost vertical rail attachment part 1c
It is fixed with screw 2.

In the figure, 6 is the roof panel, 7 is the sliding door, 8 is the door weather strip attached to the lower edge of the roof side rail 1, and 9 is the sliding door 7.
The arm 10 connected to the arm 9 is a roller that is attached to the tip of the arm 9 and rolls within the upper guide rail 3.

However, in the above configuration, the base of the seal rubber 5 is only attached to the lower end of the side wall 3a of the upper guide rail 3, and the lip 5a is attached to the arm 9 when the arm 9 passes. Since it is pressed into contact with the body and receives a downward force, it has the problem of easily falling off. In this case, it is possible to fix the seal rubber 5 with adhesive or with screws, clips, etc., but the former is not preferable in terms of installation workability, and the latter is difficult to fix because of the screws or clips. A fixing space must be secured, which is undesirable because it goes against the desire to downsize the guide rail portion as much as possible.

In view of the above-mentioned problems, the present invention has been made for the purpose of preventing the seal rubber, which serves as a dirt prevention means, from falling off in the upper guide rail portion. For this purpose, the present invention focuses on the fact that the door weather strip is disposed directly below the seal rubber, and in order to make effective use of this door weather strip, one part of the door weather strip is is pressed against the mounting base of the seal rubber, thereby preventing the seal rubber from falling off.

Hereinafter, one embodiment of the present invention will be described in detail, with the same reference numerals assigned to the same parts as those of the conventional example.

That is, in FIG. 3, the mounting base 15b of the seal rubber 15 is attached to the lower edge of the side wall 3a of the upper guide rail 3, while the lip 15a projects obliquely upward from the mounting base 15b.
is extended to the vicinity of the lower end of the side wall 3b of the upper guide rail 3, and its tip is pressed against the lower end of the outer wall 3b, thereby closing the lower part of the rail opening 4. It's all covered. Then, the base or hollow lip 8a of the door weather strip 8 is fitted directly below the seal rubber 15, that is, at the overlapping part 1d of the roof side rail outer 1a side and the roof side rail inner 1b side of the roof side rail 1. is constantly pressed against the base 15b of the seal rubber 15.

As a result, the seal rubber 15 is held in its proper position not only by the holding force of the seal rubber 15 itself but also by the holding force of the door weather strip 8, making it extremely difficult to fall off. .

In the above embodiment, when the sliding door 7 and therefore the arm 9 travel along the upper guide rail 3, the seal rubber 15 separates from the side wall 3b at a portion corresponding to the arm 9, but the arm 9 does not pass through. Once this happens, the restoring force causes it to come into pressure contact with the side wall portion 3b again. Therefore, since the rail opening 4 is entirely covered with the seal rubber 15 except for the part corresponding to the arm 9, the upper guide rail 3
It is also possible to prevent dust and other particles from entering from the outside.

As is clear from the above description, according to the present invention, the door weather strip is effectively used to press the door weather strip against the base of the seal rubber. It is possible to reliably prevent the seal rubber from falling off without using means such as clips, and there are effects such as excellent installation workability.
