  • Patent number: 8695164
    Abstract: A check link assembly for positioning a vehicle closure has a selectively positionable detent feature. The check link assembly includes an elongated link having a distal end. At least one cover is attachable to the link in a first orientation and in a second orientation. The cover has a first end, a second end, and a contoured surface between the first end and the second end. At least one member is biased against the link and is configured to ride against the contoured surface of the cover. The contoured surface at least partially defines a detent feature that interferes with the biased member to increase resistance to relative movement of the link and the biased member, thereby establishing a stop position. The detent feature is further from the distal end of the link when the cover is in the first orientation than when the cover is in the second orientation.

  • Patent number: 8607505
    Abstract: A sealing assembly is provided for a vehicle having independently opening and closing closure panels, such as first and second doors, which are hinged to a vehicle body with opposing hinges. The sealing assembly has a first seal that is mounted to the vehicle body to substantially surround a continuous door opening, and has a first membrane portion that extends over a first portion of the cutline. A second seal is mounted to a surface of the first door that faces the first membrane portion when the first door is closed. A third seal is mounted to a surface of the second door that faces the first membrane portion when the second door is closed. The first membrane portion is configured to be movable toward the closed first and second doors into contact with the second and third seals to seal the first portion of the cutline.
