  • Patent number: 11084363
    Abstract: Curling of a connection part of a second sealing member is avoided, the curling occurring in a case where the second sealing member is brought into elastic contact with a first sealing member. An end part of a third inner wall, which end part is located on a connection-part side, is thinner than the other part of the third inner wall, and at least a tip of the connection part is located on a vehicle-interior side of a vehicle-interior-side side surface of the third inner wall. A first curved wall and a second curved wall are brought into contact with each other in a case where a first end part and a second end part are caused to abut each other.

  • Publication number: 20210229539
    Abstract: A die molded part of a glass run connects an upper part of a second extrusion molded part closer to a pillar with an end of a first extrusion molded part closer to a roof. An insert panel is embedded in the die molded part with a concave shaped part of the insert panel exposed toward an exterior of an automobile. An outer garnish couples to the die molded part from the exterior of the automobile by fitting a convex shaped part of the outer garnish into the concave shaped part of the insert panel with a second anchoring part on the convex shaped part engaging with a first anchoring part on the concave shaped part. The concave shaped part includes a through hole which penetrates the insert panel in an inner-cabin and outer-cabin direction. A lid closes an inner-cabin side of the through hole.

  • Patent number: 10988012
    Abstract: Disclosed is a structure in which no gap that allows water admission between a weather strip and a glass run is formed in a situation where the weather strip at an upper frame portion of a window frame extends gradually downwardly apart from the glass run. The upper glass run portion is provided with a door panel sealing lip. The door panel sealing lip is provided with a form change point. The door panel sealing lip has a portion located closer to a center portion in a front-rear direction of the vehicle than the form change point is, and the portion contacts an upper surface of an upper frame portion and is bent outward away from a cabin. The door panel sealing lip has another portion located closer to an end than the form change point is, and the portion is not bent but extends downward.

  • Patent number: 10988010
    Abstract: A hollow seal member of a weather strip for an automobile includes a first wall and a second wall. The first wall extends toward a top end of a flange, turns toward a base root of the flange on a first bent point, and protrudes and curves outwardly toward an exterior of the automobile. The second wall extends toward a base root of the flange, turns toward the top end of the flange on a second bent point, and protrudes and curves outwardly toward the exterior of the automobile. Almost a whole inside surface between the first bent point and the second bent point includes a foamed material. Almost a whole outside surface between the first bent point and the second bent point is a film which includes a non-foamed material. An interval on the hollow seal member includes the same non-foamed material as the film.

  • Publication number: 20210107340
    Abstract: A protrusion is formed on a first part of an inner-cabin side wall of an installation base member of a protector with a sensor. The first part is closer to a connecting wall than a second part opposite the first part. The protrusion is on a virtual line in cross section. The virtual line is where convex substances, keys for example, hanging on passengers' clothes conceivably pass through. The virtual line extends toward a connecting point from a rear part of an automobile body closer to an interior of the automobile body than a reference line. The reference line is parallel with a direction in which a flange protrudes and extends from the connecting point. The connecting point is a part of an inner-cabin side end of a hollow part closest to an interior of the automobile body. The inner-cabin side end is connected with the installation base member.
