  • Publication number: 20230093362
    Abstract: An end cap couples a shutter to an upper part of a track cargo bed between left and right tracks. A shutter seal member is provided on a rear end of the shutter, and makes elastic contact with a tailgate mounted on a rear end of the truck cargo bed. A bed liner seal member is provided on rear ends of left and right side walls, and includes an installation plate member and a hollow wall. An extended wall extends vertically from part of an upper end of the hollow wall closer to an exterior of an automobile. The hollow wall has an opening at an upper part. A first horizontal surface of the end cap of a sealing structure covers an upper part of the tailgate, and a second horizontal surface faces and contactlessly approaches a top edge of the extended wall.

  • Patent number: 10406902
    Abstract: A glass run is attached to a door frame of an automobile to reduce intrusion of noise from an inside of a door of the automobile into an interior of the automobile through the glass run, while allowing a seal lip section to bend easily when a door glass is moved up and down. A partition wall having a reference surface is provided between a vehicle-interior-side seal wall and a vehicle-interior-side seal lip section. The reference surface contains: a first reference point located in the vicinity of a connection portion between the vehicle-interior-side seal lip section and the vehicle-interior-side side wall; a second reference point which is on the vehicle-interior-side side wall and located closer to a bottom wall than the connection portion; and a third reference point located in the vicinity of a tip of the vehicle-interior-side seal lip section.

  • Patent number: 10252606
    Abstract: Provided is a buffer which prevents damage to a lower edge of a baggage gateway of a baggage-containing section and which is not easily worn down or damaged when rubbed by baggage. The buffer includes a fixing section, a contact section, and a connecting section. At a vehicle-interior-side end of the connecting section, a lower surface of the connecting section is provided at a height obtained by subtracting (a) a thickness, in a vertical direction, of the vehicle-interior-side end of the connecting section from (b) a height, in the vertical direction, measured from the surface of the lower edge to a first top portion. At a vehicle-exterior side end of the connecting section, the lower surface of the connecting section is provided at a height obtained by subtracting (a) a thickness, in the vertical direction, of the vehicle-exterior-side end of the connecting section from (b) a height, in the vertical direction, measured from the surface of the lower edge to a second top portion.
