WEATHER STRIP FOR AUTOMOBILES

摘要

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.

主权项

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.
