Description

  In the present invention, a belt line inner weather strip and / or a belt line outer weather strip (hereinafter, the former is simply referred to as an inner weather strip, and the latter is simply referred to as an outer weather strip.). The present invention relates to a connection structure between a weather run and a glass run attached around a door of an automobile door.

  FIG. 1 shows a connecting portion between the inner weather strip 2 and the glass run 4 at a corner b on the rear side of the automobile front door 1a shown in FIG. 4, and FIG. 2 shows an inner weather strip 2 taken along line AA in FIG. 3 shows a cross section of the glass run 4 attached to the sash 3 taken along the line BB in FIG. 1. The inner weather strip 2 is made of rubber such as EPDM or rubber-like elastic material such as thermoplastic elastomer. A base 8 including a metal core 7 attached to the door trim 6, and a seal lip 11, 12 extending obliquely upward from an intermediate part and a lower part of the base 8 and elastically contacting the indoor side of the window glass 9. It has become more.

  The glass run 4 is a rubber-like elastic body similar to the inner weather strip 2, and is composed of the indoor side wall 4 a and the outdoor side wall 4 b and the bottom wall 4 c connecting the both side walls 4 a and 4 b. The inner side wall end and the outer side wall end extend obliquely toward the bottom wall 4c inwardly from the inner side and the outer side of the window glass 9 inserted into the glass run 4, respectively. A lip 4d, 4e that is elastically contacted and a cover lip 4f that is connected to the end of the indoor side wall and covers the sash 3 is provided. The glass run 4 extends beyond the inner weather strip 2 into the door panel below the belt line. .

  When the inner weather strip 2 and the glass run 4 are assembled, a normal gap is formed between the end of the inner weather strip shown by part e in FIG. 1 and the glass run 4, but the front door 1a is formed with this gap. Since the corner portion b is close to the ear position when seated, the reflected sound in the door leaks into the room through the gap and becomes a factor that deteriorates the sound insulation.

  There are also known ones in which an inner inner weather strip and a glass run are integrally formed (Patent Documents 1 and 2). In such a case, no gap is formed between the end of the inner weather strip and the glass run, and the above problem occurs. Although there is no inner weather strip and glass run integrated, the inner weather strip is bulky and does not turn easily, and is not easy to assemble and transport, and the inner weather strip elastically contacts the window glass when the window glass moves up and down. The seal lip and the glass run lip of the former have different bending directions in the longitudinal direction and the latter in the lateral direction. It is also costly to form them integrally by molding.
