DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drip weather strip which is mounted along a flange of a front pillar and a roof panel of an automobile.

[0002]

2. Description of the Related Art A description will be given with reference to FIGS. In the figure, a symbol is used in which one of the median lines descending from the apex angle of the isosceles triangle is painted, and the painted side represents a molded part, and the unpainted side represents an extruded part. .

[0003] Front pillar 11 of the opening edge of the body of an automobile
A substantially U-shaped base 45 fitted to the flange 20 protruding in a substantially horizontal direction on the outer surface of the base, and a narrow neck 4 on the upper surface of the base 45.
1 is provided with a hollow seal portion 42, a lip 43 protruding from the outdoor surface of the base portion 45, and a substantially U-shaped convex portion on the upper portion of a molding 50 provided along the outer surface of the front pillar 11. An extruded portion 70 that forms a latching portion 44 that sandwiches 51 and is attached along the front pillar 11;
The one in which a molded part 60 is interposed between an extruded part 80 having substantially the same cross-sectional shape and attached to the outer surface of the roof panel 12 is used.

[0004] The molded part 60 is disposed between the front pillar side flange 20 and the roof side flange 21 at the seam, that is, at the corner.

[0005] When assembling the drip weather strip 40 to the door opening edge 10 of a vehicle, one means is as follows.
FIG. As shown in FIG. 3, the assembling is performed on the front pillar side and then on the roof panel side with reference to the corner portion corresponding to the joint between the front pillar 11 and the roof panel 12. The end of the molded part 60 is aligned.

As another means, as shown in FIGS. 4 and 5, a rectangular projection 65 is formed integrally with a molded portion 60 interposed between an extruded portion 70 to be attached to the roof panel 12. The projection 65 is fitted into a notch 55 formed at the end of the molding 50, and is positioned.

However, when the conventional drip weather strip 40 is assembled to a corner portion,
In the case where the rear end of the molding 50 and the front end of the molded part 60 are visually matched, a positional shift occurs due to an assembling work variation at the time of assembling, and since there is no stopper function, after assembling, There is a problem that a shift occurs before and after.

[0008] In the one in which the protrusion 65 of the molded portion 60 is fitted into the notch 55 at the rear end of the molding 50 and positioned, the positioning function is sufficiently effective for the front, but is not effective for the rear. However, since the front end of the roof panel 12 has an arcuate portion R, there is no positioning function, slippage occurs, and the number of steps for inserting the notch 55 in the rear end of the molding 50 increases. In addition, positioning is insufficient,
When the displacement occurs, the position of the rear terminal portion changes, and the appearance becomes poor or the assembling becomes difficult.

[0009]

The problem to be solved is that the above-mentioned conventional drip weather strip is difficult to position sufficiently, causes displacement, deteriorates appearance, and makes assembly difficult. Or

[0010]

A description will be given with reference to FIGS. 1, 3, 5 to 10. A step H is formed at the joint between the front pillar flange 22 and the roof flange 23 into which the fitting groove 46 of the base 45 of the drip weather strip is fitted.
And the fitting groove 46 of the molded drip weather strip 40 to be attached to the connection portion between the front pillar flange 22 and the roof flange 23 is formed with staggered grooves 47 and 48 corresponding to the step H.

[0011]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment will now be described. 11 is a front pillar of an automobile, 12 is a roof panel, 22 and 23 are flanges protruding from the outer surfaces of the front pillar 11 and the roof panel 12 in a substantially horizontal direction, 30 is a door, Numeral 40 is a drip weather strip attached to the outer surface of the front pillar 11, 45 is a substantially U-shaped base fitted on the flange 11, and 42 is a thin neck 4 on the upper surface of the base 45.
The hollow seal portion 43 formed through the first portion 43 is a lip protruding from the outdoor surface of the base portion 45. Reference numeral 44 denotes a hook formed at the tip of the hollow seal 42 so as to hold the U-shaped convex portion 51 at the top of the molding 50 provided along the outer surface of the front pillar 10. is there. Extruded part 70 and roof panel 1 along front pillar 11
A molded part 60 is arranged between the extrusion molded part 80 along the line 2, and the molded part 60 is arranged to extend between the front pillar-side flange 20 and the roof-side flange 21.

The flanges on which the base 45 of the molded portion 60 is fitted correspond to the front pillar 11 and the roof panel 12, respectively, and are divided into flanges 22 and 23 having different heights. In the base portion 45, staggered grooves 47, 48 for fitting the respective flanges 22, 23 are formed, and a step H is provided between the two.

The operation will be described. When the drip weather strip 40 is assembled to the opening edge 10 of the vehicle body, the staggered groove 4 in the base 45 of the molded portion 60 is formed.
At 7, 48, they are fitted to the flanges 22, 23, respectively, and then assembled to the front pillar side and the roof panel side. By doing so, even if the molded portion 60 is displaced forward, the rear end of the groove 47 is
Is hung on the rear end. Also, even if it tries to shift backward, the front end of the groove 48 catches the front end of the flange 23,
Since the rearward displacement is prevented, the front and rear extruded portions 7
It is possible to completely prevent the drip weather strip from shifting in the front-rear direction, including 0 and 80.

[0014]

Since the present invention is configured as described above,
The displacement of the drip weather strip in the front-rear direction can be completely prevented, and the appearance is significantly improved.
