Patent ID: 7571569

Claim:
A glass run adapted to be mounted in 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 glass run comprising: first and second extruded portions formed by extrusion molding to be mounted on upper side and vertical side portions of the door frame; and a corner portion formed by injection molding so as to connect the first and second extruded portions with each other to be mounted on a corner of the door frame; the corner portion of the glass run including: an exterior side wall, an interior side wall and a bottom wall so as to form substantially a U-shaped cross section; an exterior seal lip and an interior seal lip that are provided in 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 a distal portion of the window glass respectively; and an interior holding lip formed by injection molding and provided on an external surface of the corner portion to be locked in a recess on the door frame, wherein an interior cover lip is provided so as to extend from a distal end of the interior side wall of the corner portion in substantially a direction in which the interior side wall extends so as to cover a side potion of a garnish mounted on the door frame, and the interior holding lip is angled to match an angle of the corner portion and formed into an L-shape between the distal end of the interior side wall and interior side cover lip; wherein a first part of the interior holding lip on the corner portion continues to an interior holding lip on the first extruded portion and has a thickness substantially same as that of the interior side holding lip on the first extruded portion and a second part of the interior holding lip on the corner portion continues to an interior holding lip on the second side portion and has a thickness substantially same as that of the interior side holding lip formed in the second extruded portion, and wherein the interior holding lip on the corner portion further comprises a third part that is thinner than other parts and is located between the first part and the second part of the interior holding lip to form a corner such that a protruding distal portion of the interior holding lip of the third part is formed at the same position as a protruding distal portion of the interior holding lip on said first and second extruded portions, a rigidity of the interior holding lip on the corner portion is made smaller than a rigidity of the interior holding lips on the first and second extruded portions by forming the interior holding lip on the corner portion to be thin, such that the interior holding lip on the corner portion is held in the recess formed on an interior side of the door frame when the glass run is mounted on the door frame.
