  • Patent number: 5127702
    Abstract: A seal structure for a front door of a motor vehicle provided with a door mirror bracket at a front end of a door belt line is composed of a roof weather strip attached along a door opening of a car body, and a door weather strip attached along a periphery of a door panel. The door weather strip is provided with an end portion covering a lower portion of the door mirror bracket and a front upper end of a door inner panel to which a lower end of the door mirror bracket is jointed. An upper part of the end portion has a thickness large enough to fill the step between the door mirror bracket and the door inner panel whereby the end portion of the door weather strip has a continuous smooth surface from its lower part to its upper part to effect a good seal with the opposed roof weather strip when the front door is closed.

  • Patent number: 5105580
    Abstract: A weather strip attached along a door opening of a motor vehicle for sealing between the door opening and a periphery of a door glass has a strip-shaped extruded portion, and a molded end portion jointed to a lower end of the extruded portion. The strip-shaped extruded portion has a longitudinally extending tubular main seal portion and a lip-shaped seal portion which defines a concave groove with the main seal portion. The molded end portion has an extended concave groove extending from the concave groove of the strip-shaped extruded portion to a rear side edge of the molded end portion. During running of a vehicle in rainy weather or during washing of the vehicle, water leaking into the concave groove flows along the extended concave groove and is drained out therefrom without staying at an end of the extended concave groove thereby preventing water from intruding into a vehicle compartment when a vehicle door is opened or closed.
