Abstract

A glass run that is excellent in appearance quality and durability, and exhibits improved sealing properties is proposed. The glass run for attachment to vertical sides of the door frame has a bottom wall for attachment to a door frame or a door molding, and an outer seal lip extending from an exterior side edge of the bottom wall. The outer seal lip has a base part extending towards a door glass, and a main part extending from the base part while curving inwardly of the base part. When the outer seal lip is deformed and bent with a side edge of the door glass, a tip end part of the outer seal lip is located inwardly of a surface of the bottom wall or the outer side wall, which faces a side edge of the door glass, and the base part is formed to have a rigidity lower than that of the main part.

First claim

What is claimed is:

1 . A glass run for an automobile, which is adapted to be attached to an inner periphery of a door frame of a door of an automobile for guiding a door glass as it is raised and lowered, wherein the glass run for attachment to vertical sides of the door frame comprising:
a bottom wall for attachment to one of the door frame and a door molding, and an outer seal lip extending from one of an exterior side edge of the bottom wall and a tip end of an outer side wall, the outer seal lip including a base part that extends towards the door glass, and a main part extending from the base part while curving inwardly therefrom such that when the outer seal lip is deformed and bent with a side edge of the door glass, a tip end part of the outer seal lip is located inwardly of a surface of one of the bottom wall and the outer side wall, which faces the side edge of the door glass.

2 . The glass run as claimed in claim 1 , wherein the base part of the outer seal lip is located in a space defined between a surface of one of the bottom wall and the outer side wall, from which the base part is extended, and a position in which the side edge of the door glass most approaches one of the bottom wall and the outer side wall, and the base part exhibits a rigidity lower than that of the main part.

3 . The glass run as claimed in one of claim 1 , wherein the main part of the outer seal lip is formed such that a curvature of the tip end part is smaller than that of he base part.

4 . The glass run as claimed in one of claim 1 , wherein the base part of the outer seal lip is formed to have a thickness less than that of the main part.

5 . The glass run as claimed in one of claim 1 , wherein a low friction sliding layer is formed on a surface of the main part of the outer seal lip, which contacts the door glass, and another low friction sliding layer is formed on the base part so as to have one of a thickness less than that of the main part, and no thickness.

6 . The glass run as claimed in one of claim 1 , wherein the bottom wall for contacting the tip end part of the outer seal lip is formed to have an inclined surface.

7 . The glass run as claimed in one of claim 1 , wherein the glass run includes the outer seal lip, the bottom wall and an inner side wall which are integrally formed with each other, and an inner seal lip is extended from the inner side wall towards the outer seal lip.

8 . The glass run as claimed in one of claim 1 , wherein the glass run includes the outer seal lip, and one of the bottom wall and the outer side wall, which are integrally formed with each other, and the inner side wall and an inner seal lip extended from the inner side wall towards the outer seal lip are formed so as to be separated from the outer seal lip and one of the bottom wall and the outer side wall.
