Abstract:
1. A combination of a glass run and an inner part of a door frame of a vehicle door to guide a window glass when the window glass moves up and down, the combination comprising: an exterior side wall, an interior side wall and a bottom wall, wherein the bottom wall is mounted to the door frame such that the bottom wall is inclined with respect to an inner surface of the door frame of the glass run, and the exterior side wall, the interior side wall and the bottom wall form a substantially U-shaped cross section; an exterior seal lip and an interior seal lip of the glass run that are provided at distal portions of the exterior side wall and the interior side wall respectively, extending toward an inside of the U-shaped cross section, so that the exterior seal lip and the interior seal lip seal an exterior surface and an interior surface of an end portion of the door window glass respectively; and a cushion material provided on a back face of the bottom wall, wherein the bottom wall is configured so that an interior side end of the bottom wall, which is continuous with the interior side wall, is brought into contact with the inner surface of the door frame, and an exterior side end of the bottom wall, which is continuous with the exterior side wall, is spaced apart from the inner surface of the door frame when the glass run is mounted in the door frame, wherein the inclination of the back face of the bottom wall with respect to the inner surface of the door frame is such that a tapered space is formed between the back face of the bottom wall and the inner surface of the door frame, wherein the tapered space extends substantially from the interior side end of the bottom wall to the exterior side end of the bottom wall and widens in the direction of the external side wall, wherein a part of the back face of the bottom wall and a part of the cushion material are brought into contact with the inner surface of the door frame, wherein an unoccupied space is formed between the cushioning material and the door frame when the window glass is not brought into pressure contact with the bottom wall, when an upper end of the window glass is brought into pressure contact with the bottom wall, the bottom wall is deformed and displaced around the interior side end thereof as a fulcrum such that the exterior side end of the bottom wall is brought into contact with the door frame, and when the window glass is pressed against the bottom wall, the unoccupied space is reduced in size by the movement of the exterior end of the bottom wall toward the door frame.
