Description

DETAILED DESCRIPTION OF THE INVENTION Industrial Field of the Invention The present invention relates to a door seal structure for a center pillar portion of an automobile.

2. Description of the Related Art FIG. 3 shows a conventional seal structure between a center pillar 1, a sash 3 of a front door 2 and a sash 5 of a rear door 4 in the upper part of a belt line of the automobile shown in FIG. A front opening weather strip 6 and a rear door opening weather strip 7 are attached to the sash 5 on the back side of the door glass guide portion, respectively. Prevents intrusion.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention In such a conventional seal structure, since there is a gap between the rear edge of the front door sash 3 and the front edge of the rear door sash 5 which face each other, the sheet metal of the vehicle body is inserted from this gap. Not only was the surface visible and the appearance was not good, but it was also a cause of wind noise.

The width of the front door sash 3 and the rear door sash 5 in the center pillar portion is narrowed upward from the belt line. Therefore, even if an attempt is made to provide a lip portion on the front door opening weather strip 6 or the rear door opening weather strip 7 in order to close the gap between both sashes, the width of the sash changes, so that the opening weather strip can be extruded with a constant cross section. It is impossible to make.

Means for Solving the Problems The present invention has been made to solve the above problems, and provides a center pillar weatherstrip having a lip portion in close contact with a rear edge of a front door sash and a front edge of a rear door sash. Provided is a door seal structure for a center pillar portion, characterized in that the center pillar weather strip is held by a weather strip holder fixed to the center pillar.

Effect According to the above configuration of the present invention, the lip portion of the weatherstrip attached to the center pillar side is in close contact with the rear edge of the front door sash and the front edge of the rear door sash to close the gap between the edges of both sashes. Of.

Embodiment Hereinafter, an embodiment of the present invention will be described in detail with reference to FIGS. 1 and 2.

In FIGS. 1 and 2, the sash 3 of the front door 2 and the sash 5 of the rear door 4 near the center pillar 1 have the same structure as the conventional one shown in FIG. 3, and on the rear side of the door glass guide portion, A front door opening weatherstrip 6 and a rear door opening weatherstrip 7 are attached to prevent intrusion of noise, water and dust.

According to the present invention, in order to close the gap between the rear edge of the front door sash 3 and the front edge of the rear door sash 5, the center pillar weather strip 8 is provided on the side of the center pillar 1.
Is provided. The center pillar weatherstrip 8 is held by a weatherstrip holder 9 fixed to the center pillar 1, and has a first lip portion 8a having a hollow cross-section that closely adheres to the edges of both sashes 3 and 5 so as to close the gap.
And a second lip portion 8b close to the inner surface of the front door sash 3 near the rear end edge thereof, and a third lip 8b close to the inner surface of the rear door sash 5 near the front end edge thereof and close to the weather strip holder 9. And a portion 8c.

The weather strip holder 9 includes a holding portion 9a for holding the center pillar weather strip 8 and the holding portion 9a.
The center pillar outer 1a of the center pillar 1 and the flange joint of the center pillar inner 1b extend from a to a flange joint portion of the center pillar 1 and a seal surface forming portion 9b forming a seal surface 9c that is in close contact with the rear door opening weather strip 7. The weather strip holder 9 is joined to the center pillar outer 1a by welding in the holding portion 9a and in the vicinity of the free end of the seal surface forming portion 9b. The free end of the seal surface forming portion 9b of the weather strip holder 9 is covered with a flange trim 10 attached to the flange joint of the center pillar 1 to prevent water leakage and rust.

Effect of the Invention Since the present invention is configured as described above, the gap between the edges of both sashes is blocked by the lip portion of the center pillar weatherstrip that closely adheres to the rear edge of the front door sash and the front edge of the rear door sash. It is possible to improve appearance and suppress wind noise.
This weather strip can be easily and inexpensively manufactured by extrusion molding of a constant cross section.

In addition, since this weather strip is held by the weather strip holder joined to the center pillar, the center pillar weather strip can be installed in existing vehicles without the need to change the design of door sashes, opening weather strips, center pillars, etc. It can be attached and can be applied to all types of vehicles regardless of changes in the shape and width of the door sash.

Further, due to the difference in the distance from the center of each door hinge, the door entry locus at the rear edge of the front door sash is almost vertical to the center pillar, whereas the door entry locus at the front edge of the rear door sash is It is considerably inclined with respect to the center pillar. For this reason, when attempting to arrange the seal surfaces of the center pillars that engage with the front door opening weather strip and the rear door opening weather strip, respectively, in an appropriate position, place the rear seal surface outside the front seal surface. In the related art, a step is formed in the central portion of the center pillar outer so as to deal with the problem, so that there is a problem that the molding is difficult and the appearance is not good. However, in the present invention, since the sealing surface on the rear side is formed on the weather strip holder, there is an effect that the center pillar outer is easily drawn.

Furthermore, since the weather strip holder is joined to the outer center pillar, the rigidity of the center pillar is improved.
