Description

  The present invention relates to a weather strip that is mounted on a front pillar and a header of a convertible vehicle, and more particularly to a molded portion of the weather strip that is connected to a roof side weather strip when the roof is closed.

  FIG. 2 shows a weather strip in part a of the convertible vehicle shown in FIG. 1. The mold forming part 1 includes an extrusion part 3 attached to the header 2 and an extrusion part 5 attached to the front pillar 4. The intermediate part is provided with a connecting part 8 to which a front end of a roof side weather strip (not shown) is contacted and connected when the roof 7 is closed. In the figure, the triangle mark indicates the mold forming part on the side of the blacked-out part, and the extrusion part on the side of the black frame part not to be filled. The same applies to the following drawings.

  As shown in FIG. 3, the mold forming portion 1 is formed so as to protrude from the connection portion 8 on the side of the extrusion forming portion 3 and has a substantially U-shaped mounting base 12 in which a core material 11 is embedded, and one side of the mounting base 12. It has hollow seal portions 13a and 13b, the attachment base 12 is attached to the flange 2a of the header 2 together with the attachment base of the extrusion molding portion 3, and the hollow seal portions 13a and 13b are extruded when the roof 7 is closed. It has the function of elastically contacting the roof front edge together with the hollow seal portions 3a and 3b of the molded portion 3 and sealing the space between the roof front edge. Then, the water indicated by the symbol W1 in FIG. 2 that has entered between the hollow seal portions 3a and 3b travels on the mounting base portion 12 and enters the hollow portion 15 to be described later from the drain port 9 to enter the hollow portion 5a of the extruded portion 5. It passes through the inside and is discharged outside the vehicle.

  As shown in FIG. 4, the extrusion molding part 5 side of the molding part 1 following the connection part 8 has a hollow part 15, a lip 17 that forms an insertion groove 16 between the hollow part 15, and the A water receiving lip 18 is provided on the outside of the lip 17, and the insertion groove 16 and the insertion groove 19 formed in the extrusion molding part 5 are inserted into the flange 4 a of the front pillar 4 and attached. When the side glass 6 is closed, the hollow portion 15 elastically contacts the front side edge of the side glass together with the hollow portion 5a of the extruded portion 5 so as to seal between the side glass front edge.

  The water receiving lip 18 is formed so as to extend from the connecting portion 8 to the connecting portion 8 and extend from the connecting portion 8, and when the roof is closed, it is applied to the front end of the roof side weather strip from below. Water that has entered from between the front end of the roof side weather strip and water that has dropped from the roof can be received, and the received water travels through the water receiving lip 18 as indicated by reference numeral W2 in FIG. At the end of the water receiving lip, the water flows into the hollow portion 15 through a drain hole 21 that opens into the hollow portion 15.

A weather strip of the type having the above-described structure is disclosed in Patent Document 1 below.
JP 2006-306355 A (FIG. 2)

The water W1 flowing into the hollow portion 15 from the drain port 9 flows in the hollow portion 15 on the side where the drain hole 21 is opened as shown by a dotted line in FIG. When the volume of the water W1 and the water W2 increases and the water W1 and W2 are concentrated on the outlet side of the drainage hole 21 where they merge, the water moves backward from the drainage hole, and the water flows into the vehicle as shown by the thin solid line in FIG. May leak.

  An object of the present invention is to solve the problem that occurs in the above-mentioned conventional weatherstrip molding part, that is, the problem that water flows backward from a drainage hole to cause water leakage into the vehicle.

The invention according to claim 1 is attached to the header, and is attached to the front pillar, the first extrusion molding portion having a hollow seal portion that elastically contacts the roof front edge when the roof is closed and seals between the roof, A second extruded portion having a hollow portion that elastically contacts the front end surface of the side glass when the side glass is closed and seals between the side glass, and the first and second extruded portions are integrally formed, and the roof side is closed when the roof is closed. The mold comprises a molding part having a connection part to which the front end of the weatherstrip is contacted and connected. The mold molding part closes a hollow part through which water flowing in from the first extrusion molding part passes and a roof. A water receiving lip for receiving water entering between the connecting portion and the front end of the roof side weatherstrip, and a discharge hole for discharging water received by the water receiving lip to the hollow portion A the molded part in weatherstripping for Blu vehicle, wherein the hollow portion, facing from the header side before the drain hole to the second extruded section inclined or curved, not block the drain hole, A rib is formed to guide water flowing from the first extrusion molding portion into the hollow portion so as to flow around the drain hole, and the rib contacts the inner wall of the hollow portion that deforms against the side glass 6 when the side glass is closed. The water flowing into the hollow portion is prevented from getting over the rib and flowing into the drain hole .

According to the present invention relating to claim 1, the water flowing into the hollow portion from the first extruded part flows bypassing the drain hole by the ribs is prevented from flowing into the drain hole is blocked by the ribs. In addition, when the side glass is closed, the ribs contact the inner wall of the hollow part to prevent the water generated from the first extruded part into the hollow part from over the ribs and flowing into the drainage hole, thereby ensuring water leakage due to backflow. Can be prevented.

  Hereinafter, the structure of the mold forming part of the weather strip according to the embodiment of the present invention will be described with reference to the drawings. In the figure, the same reference numerals are given to the same structural parts as those of the conventional mold forming part 1 shown in FIGS.

  FIG. 6 shows the connection part of the weatherstrip mold part 31 and the extrusion part 5 as the second extrusion part, as in FIG. 5, and FIG. 7 is taken along the line CC in FIG. FIG. 8 is a cross-sectional view of the main part when the connecting portion is cut in the transverse direction, and FIG. 8 is a view similar to FIG. The longitudinal cross section in the BB line is shown.

  The difference between the mold forming part 31 of the present embodiment and the conventional mold forming part 1 described above is that the inner wall of the hollow part 15 that forms the insertion groove 16 together with the lip 17 is provided on the header side of the drain hole 21. By forming a rib 32 that is a guide that is inclined from the front toward the extruded portion 5 that is the second extruded portion, a portion of the rib 32 near the drainage hole has a side glass 6 as shown in FIG. Is closed and the hollow portion 15 is deformed, it comes into contact with the inner wall of the hollow portion. Since the rib 32 is the same as the conventional molded part 1 except for the formation of the rib 32, detailed description thereof is omitted.

  According to the mold forming portion 31 of the present embodiment, the water W1 that has entered between the hollow seal portions 3a and 3b of the extrusion molded portion 3 enters the hollow portion 15 as shown by the dotted line in FIG. Then, the water W2 is guided by the rib 32 and bypasses the drainage hole 21 and reaches the end of the rib 32, and then the water W2 flowing in from the water receiving lip 18 is joined. There is no such thing that water flows backward. Even if the flow rate of the water W1 increases, a part of the rib contacts the hollow portion 15 near the drainage hole, so that the water W1 is blocked by a part of the rib and flows into the outlet side of the drainage hole 21. It can prevent and back flow of water from the drain hole.
