Abstract

A glass run is fixed on a channel of a doorframe, which includes a garnish for decorating a vehicle interior. The glass run includes an extruded portion and a molded corner portion. The molded corner portion connects two extruded portions. The molded corner portion includes a cover lip, which covers a gap between the garnish and the doorframe, and an insert lip, which is inserted into the gap. The cover lip is discontinuously formed with the insert lip.

a molded corner portion, which connects the first extrusion and the second extrusion and is adapted to be set at a corner of the vehicle door, the molded corner portion including a molded base, which has an angled body, a couple of molded side walls, each of which is formed along the molded base from one side of the molded base, a couple of molded seal lips, each of which inwardly extends from a respective one end of the molded side walls, wherein the couple of molded seal lips is adapted to seal the peripheral portion of the door glass, a molded cover lip, which is continuously formed with the cover lip of the first extrusion and outwardly extends from an inside end of an inner side wall of the couple of the molded side walls, and a molded insert lip, which is continuously formed with the insert lip of the second extrusion and outwardly extends from an inside surface of the inner side wall of the couple of the molded side walls,

wherein the molded corner portion has a first end, which is joined with the first extrusion, and a second end, which is joined with the second extrusion, and a middle part, which is located between the first end and the second end,

wherein the molded cover lip extends continuously from the first end toward the second end and terminates at a hem, which is located at an inside end of the inner side wall of the couple of the molded sidewalls and above the second end,

wherein the molded insert lip extends from the second end of the molded corner part towards the middle part in a vertical direction and terminates at a point that is between a top of the middle part and the second end, and the molded insert lip is continuously formed with the insert lip of the second extrusion at the second end, and

wherein the molded cover lip and the molded insert lip are separate from one another and discontinuous,

wherein the molded cover lip and the molded insert lip overlap with each other by a predetermined length on the molded corner portion.

2. A glass run according to claim 1, wherein a distal end of the hem decreases from the first end toward the second end, and the hem is smoothly matched with a surface of the molded seal lip.

3. A glass run according to claim 2, wherein the hem of the molded cover lip extends in an extending direction of the inner side wall of the couple of the molded side walls, and a distal end of the hem of the molded cover lip is smoothly matched with a surface of the molded seal lip.

4. A glass run according to claim 1, wherein the molded insert lip extends in a direction that is perpendicular to an extending direction of the inner side wall of the couple of the molded side walls.

7. A glass run according to claim 1, wherein

a distal end of the molded cover lip extends continuously along a distal end of the inner side wall from the first end of the molded corner portion to the hem, and

a lower end of the molded cover lip terminates at a location that is between the second end of the molded corner part and the point at which the molded insert lip terminates.

8. A glass run according to claim 7, wherein the molded cover lip is adapted to contact only one side of the interior member.

11. A glass run according to claim 1, wherein the molded insert lip is adapted to contact the interior member at the second end of the molded corner part.

5. A fixing structure for fixing a glass run to a channel of a vehicle door, comprising:

an interior member, which has a side end and is fixed along the channel of the vehicle door;

a first extrusion including a first base, which has a longitudinally elongated body, a first couple of side walls, each of which longitudinally extends along the first base from one side of the first base, a first couple of seal lips, each of which inwardly extends from an end of a respective one of the first couple of side walls, and is adapted to seal a peripheral portion of a door glass, and a cover lip, which outwardly extends from an inside end of an inner side wall of the first couple of side walls and covers the side end of the interior member of the vehicle door;

a second extrusion including a second base, which has a longitudinally elongated body, a second couple of side walls, each of which longitudinally extends along the second base from one side of the second base, a second couple of seal lips each of which inwardly extends from an end of a respective one of the second couple of side walls, and is adapted to seal the peripheral portion of the door glass, and an insert lip, which outwardly extends from an inside end of an inner side wall of the second couple of side walls and is inserted into a gap between the channel and the side end of the interior member of the vehicle door; and

a molded corner portion, which connects the first extrusion and the second extrusion and is adapted to be set at a corner of the vehicle door, including a molded base, which has a bent shape, a couple of molded side walls, each of which is formed along the molded base from one side of the molded base, a couple of molded seal lips, each of which inwardly extends from an end of one of a respective one of the molded side walls, and is adapted to seal the peripheral portion of the door glass, a molded cover lip, which is continuously formed with the cover lip of the first extrusion and outwardly extends from an inside end of an inner side wall of the couple of the molded side walls, and a molded insert lip, which is continuously formed with the insert lip of the second extrusion and outwardly extends from an inside surface of the inner side wall of the couple of the molded side walls,
