Abstract

A hollow seal member integrally molded with an installation base member includes a first hollow wall with a first bent point as a part bendable toward an outside and a second hollow wall with a second bent point as a part bendable toward the outside. A protrusion is formed on an end of a second outer-cabin side wall, which is continuous with an outer surface of the second outer-cabin side wall, protrudes upward with respect to the first hollow wall, and makes elastic contact with a door. An end of a first outer-cabin side wall connects with a position on the second outer-cabin side wall as an inner side of the hollow seal member, from which the protrusion protrudes toward the outer-cabin side. A thick part, which protrudes toward an outer side, is formed on the first outer-cabin side wall as the outer side of the hollow seal member.

Claims

1. A weather strip for automobiles comprising:

an installation base member operatively coupled along a circumferential edge of an opening of a door of an automobile body; and

a hollow seal member which is integrally molded with the installation base member and makes elastic contact with the door;

wherein;

said hollow seal member includes a first hollow wall with a first bent point and a second hollow wall with a second bent point, the first bent point being a part of the first hollow wall in a cross-sectional longitudinal direction bendable toward an outside of said hollow seal member, the second bent point being a part of the second hollow wall in a cross-sectional longitudinal direction bendable toward the outside of said hollow seal member, the first hollow wall including a first outer-cabin side wall and a first inner-cabin side wall, the second hollow wall including a second outer-cabin side wall and a second inner-cabin side wall, the first hollow wall and the second hollow wall being connected with each other in a direction that the first bent point and the second bent point are spaced out from each other;

a protrusion is formed on an end of the second outer-cabin side wall of said second hollow wall, the protrusion being continuous with an outer surface of the second outer-cabin side wall, the protrusion protruding upward with respect to the first hollow wall, the protrusion making elastic contact with said door;

an end of the first outer-cabin side wall of said first hollow wall connects with a position on the second outer-cabin side wall of said second hollow wall, the position being on an inner side of said hollow seal member, said protrusion protruding toward the outer-cabin side from the position; and

a thick part is formed on a position on the first outer-cabin side wall of said first hollow wall, the position being on an outer side of said hollow seal member, the thick part protruding toward the outer side.

2. The weather strip for automobiles as claimed in claim 1, wherein:

said thick part is gradually reduced in thickness or rigidity toward a side of said first bent point of said first outer-cabin side wall, and when said hollow seal member makes elastic contact with said door, said hollow seal member bends with said first bent point sinking toward the inner-cabin side.

3. The weather strip for automobiles as claimed in claim 1, wherein:

a top end of said protrusion is on a side of said first hollow wall with respect to a straight line which divides said hollow seal member in cross section into the side of said first hollow wall and a side of said second hollow wall.

4. The weather strip for automobiles as claimed in claim 2, wherein:

a top end of said protrusion is on a side of said first hollow wall with respect to a straight line which divides said hollow seal member in cross section into the side of said first hollow wall and a side of said second hollow wall.
