Description

  The present invention relates to a drainage structure for a weather strip of a convertible vehicle or a hard-top vehicle, which directly covers a body flange with an interior lip without using a trim member having a substantially U-shaped cross section.

  Generally, the weather strip plays a role of preventing water such as rainwater from leaking into the vehicle. However, when there is a lot of rain or when the car is washed, it is possible to dive into the vehicle by diving the waterproof function of the weatherstrip. As a countermeasure, a weather strip having a mechanism for preventing diving in the vehicle has been proposed.

  For example, a plurality of ribs are formed on the joint surface of the terminal portion with respect to the vehicle body panel, and the vehicle body panel and the plurality of ribs form a closed cross-section main water channel, and the main water channel communicates with the hollow portion of the weather strip general portion. While forming a drainage opening, a waterproof wall that connects the rib and the interior lip of the weather strip in the interior of the vehicle interior is formed to form an auxiliary water channel with a closed cross-section between the panel and the vehicle body side panel. A weather strip has been proposed in which water overflowing the water channel is discharged from the main water channel to the outside of the vehicle along with water flowing out from the drainage channel. (See Patent Document 1)

  Also, a dam portion is arranged on the inner peripheral surface of the corner where the edge of the inner peripheral surface that is curved in the width direction of the seal lip portion on the inside of the vehicle and is opened at a height equal to or higher than the level In addition, a weather strip has been proposed in which a conduction hole communicating with the inner peripheral surface of the vehicle interior seal lip portion is formed in the side wall of the hollow portion on the upstream side of the dam portion. (See Patent Document 2)

  In the case of a roofside weather strip, a water receiving lip that functions as a drainage channel is formed on the inside of the cover lip so that water collected by the water receiving lip is guided into the hollow portion of the roof side weather strip. A roof side weather strip has been proposed in which a water drain hole is formed at the inner base of the water receiving lip. (See Patent Document 3)

  Furthermore, in the case of a weather strip of the type that is held by a retainer of a convertible vehicle or a hard top vehicle, a weather strip having a mechanism for preventing diving into the vehicle as shown in FIGS. 2 to 5 has been proposed. Has been. FIG. 1 shows an overall view of a weather strip of the type held by a retainer of a convertible vehicle. The weather strip 1 includes a header extruding portion 2, a header portion mold forming portion 3, a front pillar extruding portion 4, a front pillar lower die forming portion 5, and a lower extruding portion 6. These weather strips are connected and integrated. 1 is configured.

  Further, as shown in FIG. 2, the front pillar push-out portion 4 having a retainer is fixed to a body side panel 13 having a hollow portion 9 and a weather strip 101 having a lip 10 fitted to the retainer 7 and having a flange 12. ing. The diving water flowing into the indoor lip 10 from the retainer 7 passes through a drain hole 21 provided in the front pillar mold forming part 5 communicating with the lower part of the front pillar pushing part 4, as shown in FIGS. Furthermore, the structure which discharges | emits out of the vehicle via the drain hole 15 provided in the hollow part 14 of the lower extrusion part 6 shown in FIG. 3 is taken.

  However, in the case of the weather strip having the retainer, the diving water may increase when there is a lot of rain or when the car is washed, and this diving water is provided in the front pillar lower mold part 23 of FIG. There was a problem that the drainage hole 21 in FIG. 4 could not be fully filled and overflowed into the room as indicated by the arrow in FIG. Further, in particular, in a vehicle where the distance between the flange 12 and the back surface of the lip 20 is as narrow as 1 mm to 5 mm, the mold part drainage stop wall 24 is close to the flange and is not provided on the entire back side of the lip. There was also a problem that water leaked inside the room through the wall 24 and the flange 12.

  As described above, the weather strip drainage structure of the conventional convertible car or hard top car does not enter the drain hole 21 when there is a lot of rain or when there is a lot of water, such as during a car wash. There has been a problem of overflowing inside, and there has been a demand for the development of a weather strip that does not overflow dive into the room and has excellent sealing performance.

  In view of the above problems, the present inventor has intensively studied the drainage structure of the weather strip, and has completed the present invention.
