Abstract

A glass run for guiding a door glass in a frame includes: a body having a substantially U-shaped cross-section including an outer-cabin side wall, an inner-cabin side wall longer than the outer-cabin side wall in cross section and a connecting wall which connects the side walls; an outer lip and an inner lip which are slidably brought into contact with the door glass; and a holding lip which extends from an end part of the inner-cabin side wall for fastening an inner-cabin side part of the frame together with the inner-cabin side wall. A noise insulation wall protrudes at least on the end part of the inner-cabin side wall for closing a concave space between an inner-cabin side surface of the door glass and the inner-cabin side wall.

First claim

We claim:

1. A glass run of an automobile door, for guiding a door glass in a frame, the glass run comprising:
a body having a substantially U-shaped cross-section including an outer-cabin side wall, an inner-cabin side wall which is longer than the outer-cabin side wall in cross section and a connecting wall which connects the side walls and forms a channel; an outer lip which extends toward an inner-cabin side from an end part of said outer-cabin side wall and is slidably brought into contact with said door glass; an inner lip which extends toward an outer-cabin side from a position on an outer-cabin side surface of said inner-cabin side wall and is slidably brought into contact with said door glass, the position being at a distance toward a side of said connecting wall from an end part of said inner-cabin side wall; and a holding lip which extends from the end part of said inner-cabin side wall for fastening an inner-cabin side part of said frame together with said inner-cabin side wall and elastically engages an inner-cabin side surface of the inner-cabin side part of said frame; and
a noise insulation wall protruding from the end part of said inner-cabin side wall for closing a space between an inner-cabin side surface of said door glass and the inner-cabin side wall, and the noise insulation wall integral with or separate from the glass run, a distance between said door glass and said noise insulation wall is greater than 0 mm and less than or equal to 1 mm.

2. The glass run according to claim 1 , wherein the noise insulation wall is continuous from the end part of the inner-cabin side wall for closing the space.

3. A glass run of an automobile door, for guiding a door glass in a frame, the glass run comprising:
a body having a substantially U-shaped cross-section including an outer-cabin side wall, an inner-cabin side wall which is longer than the outer-cabin side wall in cross section and a connecting wall which connects the side walls and forms a channel; an outer lip which extends toward an inner-cabin side from an end part of said outer-cabin side wall and is slidably brought into contact with said door glass; an inner lip which extends toward an outer-cabin side from a position on an outer-cabin side surface of said inner-cabin side wall and is slidably brought into contact with said door glass, the position being at a distance toward a side of said connecting wall from an end part of said inner-cabin side wall; and a holding lip which extends from the end part of said inner-cabin side wall for fastening an inner-cabin side part of said frame together with said inner-cabin side wall and elastically engages an inner-cabin side surface of the inner-cabin side part of said frame; and
a noise insulation wall protruding from the end part of said inner-cabin side wall for closing a space between an inner-cabin side surface of said door glass and the inner-cabin side wall, and the noise insulation wall protruding in a direction toward said door glass perpendicular to the inner-cabin side surface of said door glass, a distance between said door glass and said noise insulation wall prevents the noise insulation wall from making contact with the door glass.

4. The glass run according to claim 3 , wherein the noise insulation wall is continuous from the end part of the inner-cabin side wall for closing the space.

5. The glass run according to claim 3 , wherein the noise insulation wall is integral with the glass run.

6. The glass run according to claim 3 , wherein the noise insulation wall is separate from the glass run.

7. The glass run according to claim 3 , wherein the distance is less than or equal to 1 mm.
