Abstract

An outer side wall includes a bent sealing portion bent so as to be raised toward the inside of a cabin. When a window glass is closed, the bent sealing portion is elastically deformed so as to stretch along the outer surface of the window glass. The outer surface of the bent sealing portion is provided with a soft portion made of a softer material than the outer side wall.

Claims

1. A glass run for an automobile door with a window glass that is movable up and down and that is disposed in the automobile door, the glass run 1) being configured to be attached to a predetermined glass run mount that is formed along a vertically extending portion of a window frame that supports a peripheral portion of the window glass when the window glass is in a closed position within the automobile door, and 2) the glass run being configured to seal a gap between the vertically extending portion of the window frame and the window glass when the window glass is in a closed position within the window opening, wherein the glass run includes a longitudinal portion that is configured to be inserted into a forwardly opening, vertically extending recess that is formed along the glass run mount, the longitudinal portion including:

a base;

an inner side wall extending from an inner portion of the base; and

an outer side wall including

     1) a base portion extending from an outer portion of the base and

     2) a bent sealing portion, the bent sealing portion being bent and raised toward the inner side wall,

the inner side wall and the outer side wall both extending from respective portions of the base in a fore-aft direction relative to the automobile, with the outer side wall being located farther away from a cabin of the automobile than the inner side wall is when the longitudinal portion is inserted into the forwardly opening, vertically extending recess of the glass run mount,

the longitudinal portion further including an inner sealing lip extending from an exterior-facing surface of the inner side wall and being configured and arranged to be in contact with an interior surface of the window glass when the longitudinal portion is inserted into the forwardly opening, vertically extending recess of the glass run mount and the window glass is in the closed position within the window opening; and

a soft portion attached to and extending along a middle portion of an exterior-facing surface of the bent sealing portion except for a tip portion thereof, the elastomeric soft portion being made from a material that is softer than the material from which the outer side wall of the longitudinal portion is made;

the configuration and arrangement of the bent sealing portion being such that when the window glass is closed, the bent sealing portion is pressed toward an outboard wall of the forwardly opening, vertically extending recess by an exterior surface of the window glass and is elastically deformed so as to stretch along the exterior surface of the window glass, the length of the bent sealing portion in the fore-aft direction relative to the automobile being predetermined so that a tip-end portion of the bent sealing portion does not extend past a free edge of the outboard wall of the glass run mount even after maximum deflection of the bent sealing portion,

wherein an outer surface of the base portion is provided with an outer engaging recess, and

the glass run mount is provided with an outer protrusion that engages with the outer engaging recess when the glass run is inserted into the forwardly opening, vertically extending recess.

2. The glass run of claim 1, wherein the soft portion is provided to a portion of the exterior-facing surface of the bent sealing portion except for a base-end portion thereof.

3. The glass run of claim 1, wherein when the window glass is opened, the soft portion makes contact with both the exterior-facing surface of the bent sealing portion and an interior-facing surface of the outboard wall of the forwardly opening, vertically extending recess.

4. The glass run of claim 1, wherein the soft portion is comprised of an elastomeric material which presses the bent sealing portion toward the glass and the bent sealing portion is elastically deformed by the window glass.
