Opening seal for automobiles and method of preparing the same

摘要

In a wire core 20 embedded in an opening seal for automobiles, a non-thermo-fusible yarn 221 on the outer-cabin side is provided in a range 401 from a bending start position 21c forming a shoulder 21a on the outer-cabin side of a wire body 21 which is bent roughly in U-shape to a position 52 determined by offsetting a point 51 on a door internal circumference side of a base 12a of a hollow seal member 12 on the inner side whereas a non-thermo-fusible yarn 222 on the inner-cabin side is provided in a range 501 from a bending start position 21e forming a shoulder 21b on the inner-cabin side of the wire body 21 to a position 54 determined by offsetting a point 53 on an opening edge side on an inner-cabin side wall 11b of a base of a protuberance 13 with respect to the wire body 21.

1. An opening seal for automobiles, comprising: a cross section roughly U-shaped installation base member mounted on a flange including a corner part on a body side, the flange being installed along a periphery of a door opening part of a body, the installation base member including an outer-cabin side wall, an inner-cabin side wall and a connecting wall connecting the side walls;
a hollow seal member extending from an inner side position and an outer side position of said outer-cabin side wall of the installation base member respectively toward an internal circumference side and an outer circumference side of a door, which is swelled and curved toward an outer-cabin side for making elastic contact with said door thereby sealing an inside and an outside of the automobile; one or a plurality of protuberance installed inside the inner-cabin side wall of said installation base member for making elastic contact with and holding said flange; and a wire core embedded in a longitudinal direction of said installation base member while being bent roughly in U-shape, including: a skeletal wire body formed by continuously bending a wire; and non-thermo-fusible yarn which does not melt at set vulcanization temperature, is partially connected with the wire body and is roughly linearly extending in a longitudinal direction while controlling expansion of the wire body in a longitudinal direction; wherein: said wire core has at least two non-thermo-fusible yarns respectively provided on the outer-cabin side and the inner-cabin side thereof; the non-thermo-fusible yarn on the outer-cabin side is provided in a range from a bending start position forming a shoulder on the outer-cabin side of the wire body which is bent roughly in U-shape to a position determined by offsetting a point on the door internal circumference side of an inner-side base of said hollow seal member with respect to the wire body; the non-thermo-fusible yarn on the inner-cabin side is provided in a range from a bending start position forming a shoulder on the inner-cabin side of the wire body which is bent roughly in U-shape to a position determined by offsetting a point on an opening edge side on said inner-cabin side wall of a base of the protuberance which is positioned on a greater opening edge part side on the inner-cabin side wall of said installation base member among said one or a plurality of protuberance with respect to the wire body; and a straight line which connects a position of the non-thermo-fusible yarn which is closest to an opening edge of the wire body on the outer-cabin side and a position of the non-thermo-fusible yarn which is closest to an opening edge of the wire body on the inner-cabin side leans toward the internal circumference side from the outer circumference side of the door when viewed from the inside of the automobile.
