JPH11348577A - Corner piece weather strip for hard top vehicle - Google Patents

Abstract

PROBLEM TO BE SOLVED: To prevent shrinkage of a corner piece weather strip from generating clearance in an interface between a front edge and a door inner panel. SOLUTION: This corner piece weather strip has a front edge 6 in substantially parallel with a front pillar, a rear edge 7 extending from the top of the front edge 6 to the lower part of a car body, and a bag-shaped cap portion 10 covering an car body's upper corner of a corner piece on a side surface on the out-of-car side of a linking portion between the front edge 6 and the rear edge 7, and seals the corner piece positioned at the front end of a door waist portion. In this case, a projection 11 abutting to a car body front corner of the corner piece is provided for the front edge 6. Thus, because one side defining the front edge of the corner piece expands the front edge 6 of the corner piece weather strip 5 to a certain length, the corner piece weather strip 5 is mounted to a given position without any clearance.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a corner piece weather strip for a hard-top vehicle.

[0002]

2. Description of the Related Art There is known a hardtop vehicle having a substantially triangular corner piece attached to a front end of a door waist portion.

[0003] The corner piece above the door waistline is sealed by a corner piece weather strip 20.

[0004] Corner piece weather strip 20
As shown in FIG. 5, a front edge 21 having a fitting groove 29 into which a flange 25 described later fits, a rear edge 22,
And is integrally connected to a front end of a door weather strip (not shown) on the vehicle body front side by molding. And it is attached to the flange part 25 of the upright wall 24 shown in FIG. 6 which is bent from the door inner panel 23 and protrudes above the door waist line. Reference numeral 26 denotes a door outer panel.

The upright wall 24 has a front end face 27 formed on the front side of the vehicle body. The front end face 27 forms a step-like step as shown in FIG.

[0006]

However, the corner piece weather strip 20 has a dimensional variation due to shrinkage after molding. If it is excessively contracted, the front edge portion 21 of the corner piece weather strip 20 rides on the front end surface 27 of the door inner panel 23 at the time of mounting, as shown in FIG. The front edge 21 could not be fixed at a predetermined position.

As a result, a gap 28 is generated at the mating surface between the front edge 21 and the flange 25 of the corner piece weather strip 20, which causes a problem that airtightness is reduced and wind noise is generated.

[0008]

SUMMARY OF THE INVENTION The present invention is directed to a front edge substantially parallel to a front pillar, a rear edge extending downward from the upper end of the front edge to the vehicle body, a front edge and the rear edge. A bag-shaped cap portion that covers the upper corner of the vehicle body of the corner piece on the vehicle outer side surface of the connection portion with the portion, and the corner piece weather strip that seals the corner piece located at the front end of the door waist portion, A protrusion is provided on the outer side surface of the vehicle at the lower end of the front edge so as to abut on the front corner of the vehicle body of the corner piece. Even if the dimensions of the front edge of the corner piece weather strip vary due to shrinkage, the front edge of the corner piece weather strip is always
Stretched to a certain length. As a result, the front edge of the corner piece weather strip can always be fixed at a desired position.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described in detail with reference to the drawings.

FIG. 1 shows a side view of an automobile, and FIG.
FIG. 2 shows an enlarged view of a portion A in FIG. 1. In this embodiment, the door inner panel 23 and the door outer panel 26 at the front end of the door waist 2 are formed in the same manner as in FIG.

At the front end of the waist portion 2 of the door main body 1, FIG.
1, a substantially triangular corner piece 4 having a door mirror 3 is attached. The peripheral edge of the corner piece 4 is sealed by a corner piece weather strip 5.

This corner piece weather strip 5
Is integrally connected by molding to a front end of the door weather strip (not shown) attached to the door body 1 on the vehicle body front side.

The corner piece weather strip 5
As shown in FIG. 3, the front edge 6 is bent in a substantially V shape, and extends along the front pillar, and a wide rear edge 7 extending downward from the upper end of the front edge 6 toward the vehicle body. Consists of

The front edge 6 has the same sectional shape as that of the prior art shown in FIG. 7, and has a fitting groove in which the flange 25 of the door inner panel 23 fits.

The rear edge portion 7 is formed to have a substantially U-shaped cross section having an opening on the rear side of the vehicle body, and guides the front edge of the door glass (not shown) on the vehicle front side in a slidable manner. An engagement claw 8 having a substantially L-shaped cross section is provided on the vehicle exterior side surface of the edge portion 7.

Further, a bag protruding in a substantially triangular prism shape and having an open end face on the lower side of the vehicle body is formed on a vehicle exterior side surface of a top portion 9 serving as a connecting portion between the front edge portion 6 and the rear edge portion 7 of the corner piece weather strip 5. A cap portion 10 is provided.

A substantially triangular pyramid-shaped projection 11 having a bottom surface in contact with the front corner 13 of the vehicle body of the corner piece 4 is provided on the outer side surface of the lower end of the front edge 6 of the corner piece weather strip 5. I have.

In the corner piece weather strip 5 configured as described above, the door inner panel 23
The fitting groove of the front edge 6 of the corner piece weather strip 5 is fitted and fixed to the flange 25 of the corner piece.

As shown in FIG. 4, the upper corner portion 12 of the corner piece 4 is inserted into the cap portion 10 of the corner piece weather strip 5, and
An engaging claw 8 of the corner piece weather strip 5 is engaged with the rear end edge of the vehicle body of the corner piece 4 and is attached to the corner piece weather strip 5.

Further, when the vehicle body front corner 13 of the corner piece 4 abuts on the projection 11, the front edge of the corner piece weather strip 5 with respect to the vehicle body front corner 13 and the vehicle body upper corner 12 is formed. The relative position of the part 6 is always maintained in the desired position.

That is, positioning when the corner piece 4 is attached to the corner piece weather strip 5 can be easily performed.

Even when the size of the front edge 6 of the corner piece weather strip 5 varies due to shrinkage, the front edge 6 of the corner piece weather strip 5 is always constant by one side which is the front edge of the corner piece 4. Stretched to length. Therefore, the front edge portion 6 of the corner piece weather strip 5 is attached to the intended position of the flange portion 25 without a gap, so that airtightness can be obtained, wind noise can be prevented, and appearance can be prevented. Does not impair the appearance.

[0023]

According to the first aspect of the present invention, even when the size of the front edge of the corner piece weather strip varies due to shrinkage, the front edge of the corner piece weather strip is formed by one side serving as the front edge of the corner piece. The part is always stretched to a certain length so that it can be installed in the desired position at the front end of the door waist.

Therefore, there is no gap at the front end of the door waist, airtightness can be obtained, wind noise can be prevented from occurring, and the appearance can be improved.
