  • Publication number: 20210347238
    Abstract: Provided is a door weather strip that provides excellent closing performance of a door and sound insulation properties, and does not impair the appearance. A door weather strip includes a mounting base and a hollow seal portion. The mounting base has a hole penetrating the mounting base, and the hole is mounted with a valve penetrating the mounting base. At the time of manufacturing a vehicle, the door is closed with the valve open, so that the air within the hollow seal portion is discharged to compress and shape the hollow seal portion (first step). When the door is opened, the valve is closed to retain the shaped state of the hollow seal portion (second step). The valve is opened again at a time point when the hollow seal portion begins to come into contact between the door and the vehicle body opening while the door is closing, or at a time point when the door is closed (third step).

  • Patent number: 9327584
    Abstract: A glass run capable of preventing noises from intruding into an automobile compartment from an interior of an automobile door via glass runs during running of an automobile. The glass run includes extruded parts and molded parts. Each of the extruded parts and the molded parts has a bottom wall, an outer side wall, and an inner side wall, which define a generally U-shaped cross-section. An outer seal lip and an inner seal lip respectively extend from open ends of the outer side wall and the inner side wall towards the interior of the glass run.

  • Publication number: 20090001772
    Abstract: A roof weather strip includes a fitting base part and a seal part having a hollow part. The seal part has a sealing wall which is configured to be brought into pressure contact with a peripheral part of a roof panel forming a roof opening, when a movable roof closes the roof opening. The seal part also has an upper connecting region so as to connect the sealing wall to an upper part of the fitting base part. The upper connecting region is provided with a corrugated part on its inner face opposed to the hollow space, and the corrugated part has a plurality of convex parts and concave parts which are alternately formed. An arm part is integrally formed so as to extend from the fitting base part downward at an outer peripheral side, and a distal end of the arm part is connected to a lower end of the seal part. Because a plurality of the concave parts of the corrugated part exist in the upper connecting region, stress is easily dispersed.
