  • Patent number: 6837005
    Abstract: A weatherstrip for an automobile includes an attaching portion having an inverse U-shape cross section. A rising portion is formed in a protruding manner on the attaching portion and lip pieces are formed for sealing between a door inner panel and a window glass. The rising portion includes a sloping guide that leads to a concave groove with which the trim end of a trim is fitted and latched. To attach the weatherstrip to the upper edge of an inner panel of a door beltline, the attaching portion is attached to the flange by insertion. Then the trim end of the trim is pressed against the guide and is, thrust so as to be fitted and latched with the concave groove. Since the trim end need not climb over the flange while keeping a weatherstrip attached thereto, even if the angle created by the door beltline and a pillar is an acute angle, the creation of a large gap between the weatherstrip end and the pillar is eliminated.
