Document Type and Number:
WIPO Patent Application WO/2020/080033
Kind Code:
A1
Abstract:
Provided is a door weatherstrip which has excellent door closing performance and sound insulation properties and does not impair the appearance. The door weatherstrip 10 has a mounting base 20 and a hollow seal portion 30, the mounting base 20 has a hole 22 penetrating through the mounting base 20, and a valve 40 that penetrates the mounting base 20 is mounted in the hole 22. During the manufacture of a vehicle, by closing the door with the valve 40 open, air in the hollow seal portion 30 is evacuated so as to compress and shape the hollow seal portion 30 (first step). When the door is opened, the valve 40 is closed to maintain the shape of the hollow seal portion 30 (second step). Again, when, during the door closing operation, the hollow seal portion 30 starts to be in contact between the door and a vehicle body opening, or when the door is closed, the valve 40 is opened (third step).
