Abstract

An outer lip 26 is forked into an inner-attaching lip 26X and an outer-attaching lip 26Y, wherein the outer-attaching lip 26Y is set on a position where a top end 26a thereof is not drawn toward a connecting wall 24 side by the door glass 9; a folding point 60 is formed on a connecting wall 24 side of a base root 26d of the inner-attaching lip 26X for turning the inner-attaching lip 26X toward the connecting wall 24 side; thickness 31 of the base root 26d of the inner-attaching lip 26X is thicker than thickness 32 on the folding point 60 and thickness 34 of the base root 26b of the outer-attaching lip 26Y is thinner than thickness 33 of the top end 26a; and the outer-attaching lip 26Y follows turn of the inner-attaching lip 26X and is slidably brought into contact with the door glass 9.

Claims

1. A glass run for guiding a door glass lifting or lowering into a ditch, which is fittable along a frame having a substantially U-shape in cross section of an automobile door, the glass run comprising:

a body having a substantially U-shape in cross-section including an inner-cabin side wall, an outer-cabin side wall and a connecting wall which connects the side walls;

an inner lip which is extending toward said connecting wall side from an inner surface of said inner-cabin side wall and slidably brought into contact with said door glass; and

an outer lip which is extending toward an inner-cabin side from an inner surface of an end of said outer-cabin side wall and slidably brought into contact with said door glass, the outer lip being forked into an inner-attaching lip which extends toward said connecting wall side from an inner surface of the end of said outer-cabin side wall and faces said inner lip and an outer-attaching lip which extends substantially perpendicularly to a direction in which the inner-attaching lip extends from an opposite side to said connecting wall side of a base root of said inner-attaching lip;

wherein

before said door glass is guided into said ditch, the outer-attaching lip of said outer lip is set on a position where a top end of the outer lip does not touch the door glass guided into said ditch or, even in case the top end touches the door glass, the top end of the outer lip is not drawn toward the connecting wall side by the door glass;

a folding point is formed by thinning thickness of said connecting wall side of the base root of said inner-attaching lip or by forming a notch from an inner-cabin side for turning said inner-attaching lip toward said connecting wall side;

thickness of the base root of said inner-attaching lip is thicker than the thickness on said folding point and thickness of the base root of said outer-attaching lip is thinner than thickness of the top end of the outer-attaching lip; and

when said door glass is guided into said ditch and slidably brought into contact with said inner-attaching lip, the inner-attaching lip turns toward said connecting wall side around said folding point, said outer-attaching lip approaches said door glass side and is slidably brought into contact with the door glass following movement of said inner-attaching lip, and the top end of said outer-attaching lip bends and moves toward an opposite side to said connecting wall side along said door glass.

2. The glass run as claimed in claim 1, wherein:

said folding point is formed on a position away from an end of an outer-cabin side part forming said frame toward a opposite side to said connecting wall side, which is either on an extension line of an inner-cabin side surface of the outer-cabin side part forming said frame or on the outer-cabin side of the extension line.

3. The glass run as claimed in claim 1, wherein:

thickness of the base root of said outer-attaching lip is formed by cutting off an inner-cabin side or an outer-cabin side of the outer-attaching lip or by forming a notch from the inner-cabin side or the outer-cabin side.

4. The glass run as claimed in claim 1, wherein:

said inner-attaching lip is formed at an interval from said outer-cabin side wall so that the inner-attaching lip does not abut the outer-cabin side wall when the inner-attaching lip is slidably brought into contact with the door glass.

5. The glass run as claimed in claim 1, wherein:

said glass run is continuous vertically crossing over a position at least on a belt line relative to said automobile door.

6. The glass run as claimed in claim 2, wherein:

thickness of the base root of said outer-attaching lip is formed by cutting off an inner-cabin side or an outer-cabin side of the outer-attaching lip or by forming a notch from the inner-cabin side or the outer-cabin side.

7. The glass run as claimed in claim 2, wherein:

said inner-attaching lip is formed at an interval from said outer-cabin side wall so that the inner-attaching lip does not abut the outer-cabin side wall when the inner-attaching lip is slidably brought into contact with the door glass.

8. The glass run as claimed in claim 3, wherein:

said inner-attaching lip is formed at an interval from said outer-cabin side wall so that the inner-attaching lip does not abut the outer-cabin side wall when the inner-attaching lip is slidably brought into contact with the door glass.

9. The glass run as claimed in claim 6, wherein:

said inner-attaching lip is formed at an interval from said outer-cabin side wall so that the inner-attaching lip does not abut the outer-cabin side wall when the inner-attaching lip is slidably brought into contact with the door glass.

10. The glass run as claimed in claim 2, wherein:

said glass run is continuous vertically crossing over a position at least on a belt line relative to said automobile door.

11. The glass run as claimed in claim 3, wherein:

said glass run is continuous vertically crossing over a position at least on a belt line relative to said automobile door.

12. The glass run as claimed in claim 6, wherein:

said glass run is continuous vertically crossing over a position at least on a belt line relative to said automobile door.

13. The glass run as claimed in claim 4, wherein:

said glass run is continuous vertically crossing over a position at least on a belt line relative to said automobile door.

14. The glass run as claimed in claim 7, wherein:

said glass run is continuous vertically crossing over a position at least on a belt line relative to said automobile door.

15. The glass run as claimed in claim 8, wherein:

said glass run is continuous vertically crossing over a position at least on a belt line relative to said automobile door.

16. The glass run as claimed in claim 9, wherein:

said glass run is continuous vertically crossing over a position at least on a belt line relative to said automobile door.
