Weather strip for automobile
First Claim
1. A weather strip for an automobile, comprising:
- a base portion to be mounted along an opening of a window of an automobile body;
a seal portion projecting from said base portion to come in contact with a window glass;
said seal portion being composed of a pair of dogleg-shaped portions each having an upper half portion above a respective bend and a lower portion below the respective bend, said dogleg-shaped portions defining a hollow portion having a nearly lozenge-shaped section and a top, and a lip portion extending upwards from the top of said hollow seal portion as an approximately coplanar extension in an extending direction, of the upper half portion of one of said pair of dogleg-shaped portions, said lip portion being positioned to be pressed by said window glass when said window glass is closed;
the thickness(T1) of said lip portion, the thickness(T2) of said one of said pair of dogleg-shaped portions, and the thickness(T3) of the other of said dogleg-shaped portions having a relation expressed by the following inequality;
T1>
T2>
T3; and
said lip portion extending in a direction which is more nearly vertical as compared with said extending direction of said upper half portion of said one of said pair of dogleg-shaped portions.

Abstract
A weather strip has a base portion to be mounted along an opening of a window of an automobile body and a seal portion projecting from the base portion to be come in contact with a window glass. The seal portion is composed of a pair of dogleg-shaped portions defining a hollow poriton of a nearly lozenge-shaped section, and a lip portion extending from a top of the hollow seal portion in a direction along an upper half portion of one of the pair of dogleg-shaped portions. The lip portion is pressed by the window glass when the window glass is closed. The thickness (T1) of the lip portion, the thickness (T2) of one of the pair of dogleg-shaped portions, and the thickness (T3) of another one of the pair of dogleg-shaped portions have a relation expressed by the following inequality:T1>T2>T3. And the lip portion extends in a direction approximate to a vertical direction as compared with the extending direction of the upper half portion of the one of the pair of dogleg-shaped portions. By providing a difference in thickness between the dogleg-shaped portions and the lip portion, an undesirable increase of the pressing load can be prevented, and accordingly, the seal force of the weather strip can be made uniform regardless of the change of the fitting condition of the window glass to the opening of the window.
