Abstract

PROBLEM TO BE SOLVED: To efficiently prevent water from entering a cabin by providing a plurality of projections in the inner surface of a door glass run and at the same time forming a plurality of spaces so as to exhibit a labyrinth effect. SOLUTION: A first projection 6 is provided in the inner surface of a sidewall part 2 and a second projection 8 is provided in the inner surface of a bottom part 7. When a door glass G is fitted into a door glass run 1 to be closed, the first projection 6 is made to abut on the vehicle-side side surface of the door glass G and at the same time is projected so as to form a first space 9 between the tips of an outer lip 3. Also, a second space 10 is formed between the first projection 6 and the second projection 8, and a third space 11 is formed between a sidewall part 4 and an inner lip 5. High pressure water W enters the first space 9 from a narrow path N1 and then enters the second wide space 10, so that water is prevented from entering a cabin by the so-called labyrinth effect, that is, an effect that a fluid is abruptly expanded to lower a pressure and to lose the energy of a fluid.

In the (A line cross section), when a large amount of high-pressure water W is directly hit as shown by the arrow when washing the vehicle, the upper end G _{1 of the} closed door glass G is in close contact with the inner surface of the door glass run 12 even if the water tries to enter the indoor side. As a result, the intrusion route is not blocked and water does not enter.

目的とする。However, in the center pillar cross section (BB cross section) shown in FIG. 5, when the high-pressure water W is directly hit as shown by the arrow, the side edge G ₂ of the door glass G and the door glass run 12 are shown. Since there is usually a gap S between the inner surface and the inner surface of the vehicle, water easily passes through the gap S into the vehicle interior as indicated by the arrow. In particular, if there is a step at the joint between the die-molded portion and the extruded-molded portion, there is a problem that water can easily enter from this portion. Therefore, the present invention has been made in view of such a conventional problem,
It is an object of the present invention to provide an automobile door glass run capable of preventing high pressure water from entering the center pillar portion as well.

In FIG. 1, reference numeral 1 denotes a door glass run fitted to a door sash E, which has a substantially U-shaped cross section and is provided with an outer lip 3 on a side wall portion 2 on the vehicle outer side and an inner lip 5 on a side wall portion 4 on the vehicle inner side. ing. A first projection 6 is provided on the inner surface of the side wall portion 2, and a second projection 8 is provided on the inner surface of the bottom portion 7. When the door glass G is fitted into the door glass run 1 and is closed, the first protrusion 6 abuts on the vehicle outer side surface of the door glass G, and a first space is provided between the door glass G and the tip of the outer lip 3. 9 is formed so as to be formed. A second space 10 is formed between the first protrusion 6 and the second protrusion 8. Further, a third space 11 is formed between the side wall portion 4 and the inner lip 5.

Even if it opens and penetrates, the first protrusions 6 serve as a barrier, making it difficult to jump into the passenger compartment. Also, high pressure water W
Enters the wide first space 9 from the narrow passage N ₁ in the outer lip 3 portion that has entered as described above, and then again enters the wide second space 10 via the narrow passage N ₂ in the first protrusion 6 portion. Although it goes through the path, the so-called labyrinth effect, that is, the effect that the fluid abruptly expands and the pressure decreases and the energy of the fluid is lost by repeating the narrow path through the wide space, is repeated multiple times as described above, It is decompressed by and becomes difficult to penetrate into the passenger compartment.

Then, the high-pressure water W does not enter the third space 11 and flows into the space 11 as a drainage channel C as shown in FIG.
