  • Patent number: 9738146
    Abstract: A hollow seal member integrally molded with an installation base member includes a first hollow wall with a first bent point as a part bendable toward an outside and a second hollow wall with a second bent point as a part bendable toward the outside. A protrusion is formed on an end of a second outer-cabin side wall, which is continuous with an outer surface of the second outer-cabin side wall, protrudes upward with respect to the first hollow wall, and makes elastic contact with a door. An end of a first outer-cabin side wall connects with a position on the second outer-cabin side wall as an inner side of the hollow seal member, from which the protrusion protrudes toward the outer-cabin side. A thick part, which protrudes toward an outer side, is formed on the first outer-cabin side wall as the outer side of the hollow seal member.

  • Patent number: 8181397
    Abstract: A retention structure for retaining a sash molding end of a sash molding is provided. A weatherstrip and the sash molding are attached along a door sash. A hard material clip is insert-molded in the die-molded part at the end of the weatherstrip. The clip has a latch protruding from the die-molded part. An end cap die-molded at the sash molding end has an engaging part. The engaging part engages with the latch to retain the sash molding end.

  • Patent number: 8152229
    Abstract: A sunroof apparatus for opening or closing an opening formed on a fixed roof of an automobile includes: a movable front panel and a movable rear panel both provided in the fixed roof; a panel frame made of engineering plastic and attached around one of the panels; a hollow elastic weatherstrip attached around the panel frame attached around the one of the panels; a panel frame made of the engineering plastic and attached on a periphery end section of other one of the panels, the other one of the panels having a butt end section and the periphery end section; and a hollow elastic weatherstrip attached to the panel frame attached to the other one of the panels, wherein the opening is closed when the weatherstrip of the one of the panels and the butt end section of the other one of the panels butt against each other. This structure can enhance efficiency in molding weatherstrips since the weatherstrip attached around the two panels are in a hollow structure.

  • Patent number: 6811213
    Abstract: There is provided a weather strip for use on a sunroof capable of preventing squeak noises being generated in advance between a hollow seal part and a roof panel during traveling of a car by allowing the hollow seal part to satisfactorily follow vibrations of the roof panel. The weather strip ensures sealing property between a roof glass mounted on the sunroof of a car and a roof panel and comprises a built-in base part attached to the roof glass, and a hollow seal part composed of continuous ends integrally formed with the built-in base part and having substantially a circular cross section, a tip end contact part elastically contacting the roof panel, wherein thicker parts protruding inward and being continuous with the built-in base part are formed on the continuous ends of the hollow seal part and protrusions protruding inward are formed on substantially middle parts between the continuous ends and the tip end contact part.
