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.

Claims

1. A glass run for sealing a door glass, the glass run fixed on a channel of a vehicle door, comprising:

a first extruded portion 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 one of the first couple of side walls, wherein the first couple of seal lips is adapted to seal a peripheral portion of the 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 is adapted to cover an interior member of the vehicle door;

a second extruded portion 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 one of the second couple of side walls, wherein the second couple of seal lips 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 adapted to be inserted into a gap between the channel and the interior member of the vehicle door; and

a molded corner portion, which connects the first extruded portion and the second extruded portion 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 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 extruded portion 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 extruded portion and outwardly extends from an inside surface of the inner side wall of the couple of the molded side walls;

wherein the molded cover lip is discontinuously formed with the molded insert lip at the molded corner portion.

2. A glass run according to claim 1, wherein the molded cover lip is gradually sloped down along the molded base, and a hem of the molded cover lip is smoothly matched with a surface of the molded seal lip.

3. A glass run according to claim 1, wherein the molded cover lip and the molded insert lip overlap each other by a predetermined length on the molded corner portion.

4. A glass run according to claim 1, wherein the molded cover lip extends toward an extending direction of the inner side wall of the couple of the molded side walls, and a hem of the molded cover lip is smoothly matched with a surface of the molded seal lip.

5. A glass run according to claim 1, wherein the molded insert lip extends toward a perpendicular direction of an extending direction of the inner side wall of the couple of the molded side walls, and a hem of the molded cover lip is smoothly matched with a surface of the molded seal lip.

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

an interior member, which is fixed along the channel of the vehicle door;

a first extruded portion 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 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 an interior member of the vehicle door;

a second extruded portion 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 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 interior member of the vehicle door; and

a molded corner portion, which connects the first extruded portion and the second extruded portion 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 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 extruded portion 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 extruded portion and outwardly extends from an inside surface of the inner side wall of the couple of the molded side walls, wherein the molded cover lip is discontinuously formed with the molded insert lip at the molded corner portion;

wherein the interior member is continuously curved along the molded cover lip.

7. A fixing structure for fixing a glass run according to claim 6, wherein a curved portion of the interior member is covered by the molded cover lip.

8. A glass run for sealing a door glass, comprising:

a molded corner portion of a glass run fixed on a channel of a vehicle door, wherein the molded corner portion includes;

a base having a bent shape;
