Glass run and method of assembling door glass on glass run

摘要

A glass run includes a forked outer lip, wherein: one interval between a base root and an intermediate part of the inner lip is swelled and curved toward an inner-cabin side wall side and another interval between the intermediate part and a top end is swelled and curved toward an outer-cabin side wall side; a displacement point is on the connecting wall side compared with a top end of the outer-attaching lip of the outer lip; and the door glass abuts the inner lip and slidably moves toward the top end side and an outer-cabin side surface of the door glass abuts the outer-attaching lip and the inner-attaching lip while an inner-cabin side surface of the door glass abuts the inner lip.

主权项

1. A glass run of an automobile door, for guiding a door glass in a frame having a substantially U-shaped cross section, the glass run comprising:
a body having a substantially U-shaped cross-section including an inner-cabin side wall, an outer-cabin side wall and a connecting wall which connects the side walls and forms a channel; an inner lip which extends toward a connecting wall side from an outer-cabin side surface of said inner-cabin side wall and is slidably brought into contact with said door glass; and an outer lip which extends toward an inner-cabin side from an inner side surface of an end position of said outer-cabin side wall and is 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-cabin side surface of the end position of said outer-cabin side wall and which faces said inner lip; andan outer-attaching lip which is substantially perpendicular to a direction in which the inner-attaching lip extends from a base root of the inner-attaching lip and which extends toward an opposite direction from said connecting wall side; wherein: said inner lip substantially has an S shaped cross section, wherein a first portion between a base root of said inner lip and an intermediate part of said inner lip has a convex shape toward said inner-cabin side wall side and a second portion between the intermediate part and a top end of said inner lip has a convex shape toward said outer-cabin side wall side; an inflection point of the S shaped inner lip, on which a direction of a curve of said inner lip changes, is closer to said connecting wall than a top end of the outer-attaching lip of said outer lip; and the base root of the inner lip has a connecting wall side surface which is closer to the connecting wall than the top end of the outer-attaching lip.
