Abstract
A weather-strip for an automobile door adapted to be mounted on the edge of the door and closely contact with a body of the automobile when the door is closed, thereby preventing any foreign matter from entering into the automobile. The weather-strip comprises a base section which is to be mounted on the edge of the door and a hollow seal section integrally formed with the base section. The hollow seal section comprises a first wall having a protrusion formed at the upper end thereof, a second wall and a mountain-shaped top wall having a ridge formed therein. The hollow seal section is adapted to collapse when the door is closed, thus providing a positive sealing effect for the automobile door.
Claims3
A weather-strip for an automobile door composed of an elastic rubber-like material and of a uniform cross sectional shape throughout its length and adapted to be mounted on an edge of the door and closely contact with a body of the automobile when the door is closed, said body having a first section parallel to the plane of the door opening and a second section generally perpendicular to said first section, said weather-strip comprising:
- a base section adapted to be mounted on the edge of the door;
- and
- a hollow seal section integrally formed with said base section;
- said hollow seal section comprising:
- a first wall projecting from said base section and having a sealing surface formed thereon;
- a protrusion continually and integrally formed with said first wall, said protrusion having a sealing surface formed thereon;
- a second wall projecting from said base section;
- and
- a mountain-shaped top wall integrally formed with said first and second walls, said top wall having a ridge formed therein, said hollow seal section having first, second and third bends between said first wall and said top wall, said second wall and said top wall, and at the ridge of said top wall, respectively;
- wherein said seal section is adapted to collapse when the door is closed in such a way that the sealing surfaces of said first wall and said protrusion are brought into a press contact with the first section of said body and the ridge of said top wall is brought into a press contact with the second section of said body.
A door seal assembly for an automobile, comprising:
- a door;
- a body panel for receiving said door, said body panel having a first edge parallel to the plane of the door opening and a second edge which is generally perpendicular to the first edge;
- and
- a weather-strip comprising an elastic rubbery strip of uniform cross-section for mounting around an edge of said door, said weather-strip comprising:
- a base section mounted on the edge of said door;
- a hollow seal section outstanding from said base section;
- said hollow seal section comprising:
- a first wall outstanding from said base section and having a sealing surface formed thereon;
- a second wall outstanding from said base section;
- a protrusion continuously and integrally formed with said first wall, said protrusion having a sealing surface formed thereon;
- and
- a convex top wall for interconnecting said first and second walls, said top wall having a ridge formed therein, said hollow seal section having first, second and third bends between said first and top walls, said second and top walls, and at the ridge of said top wall, respectively;
- wherein said seal section is adapted to collapse when the door is closed in such a way that the sealing surfaces of said first wall and said protrusion are brought into a sealing contact with the first edge of said body panel and the ridge of said top wall is brought into a sealing contact with the second edge of said body panel.
