Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a front wind molding of an automobile, and more particularly to a front wind molding having means for preventing airflow from passing through a gap along the front wind molding when the automobile is traveling.

[0002]

2. Description of the Related Art As shown in FIG. 2, a front window opening edge of a vehicle body including a front pillar 1 and a windshield 3.
A front wind molding (hereinafter, simply referred to as molding) 4 is mounted between the outer circumference and the outer circumference. FIG. 3 (A) shows a cross-section of the molding 4 along the front pillar 1 in a mounted state (cross-section taken along the line IIIA-IIIA in FIG. 2). 1
And the windshield 3 bonded and fixed to this with an adhesive 5.
It is mounted between the outer periphery of the head, the head 41, the legs 42,
It has lips 43, 44. Reference numeral 50 is a dam that prevents the adhesive 5 from flowing out. The molding 4 and its mounting structure are common over the entire length of the front window opening edge including the front pillar 1.

By the way, when the automobile is running, the air flow is in the mall 4.
To the outside at the upper edge 10 of the front window opening through the gap 6 between the molding 4 and the front pillar 1 (arrow shown in the figure). At this time, a so-called grass whistle sound may be generated.

As a general means for preventing the generation of this whistle sound, as shown in FIGS. 2 and 3 (B), a sponge rubber for sealing the gap 6 on the side surface of the molding 4 at an intermediate position of the front pillar 1. The elastic sealing material 7 such as is attached. However, it is extremely difficult to form a size and shape that completely fills the void 6, and the void 60 remains between the seal material 7 and the molding 4 and the front pillar 1, and the whistle noise cannot be completely prevented. . Therefore, it is conceivable to make the sealing material 7 large, but if it is made large, the gap 60
However, the head 41 of the molding 4 is pushed by the sealing material 7 and partially lifts up, resulting in poor appearance. .

[0005]

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a molding capable of sealing a gap between the molding and the front pillar at a low cost so as not to generate a whistle noise. Is.

[0006]

According to the present invention, as shown in FIG. 1, a molding 4 having a head 41, a leg 42 and lips 43 and 44 extending from the leg ends to both sides, particularly a molding along a front pillar 1. It is characterized in that a wall 45 that closes the gap 6 between the molding 4A and the front pillar 1 is integrally formed in the molding portion of 4A.

The forming point is the molding portion 4 at the lower end of the molding 4A.
C may be used. Mall 4 along the front pillar 1
Corner molding may be used to connect A and the molding 4B along the upper edge 10 of the front window opening, and a wall that closes the void 6 may be formed in this.

[0008]

The wall 45 can be easily formed by using the molding portion 4C and the corner molding portion 4D at the lower end of the molding 4.
Further, at the time of molding, the wall 45 can be molded into a desired shape, and the gap 6 can be sealed so as not to cause a whistle noise.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows an embodiment of the present invention, in which an extrusion molding molding 4A along a front pillar 1 forming a vertical edge of the front window opening edge and an extrusion molding along an upper edge thereof are formed. A molding 4 made of synthetic resin, which is connected to the molding 4B by a molding portion 4D, is mounted.

The molding 4 has a common cross-sectional shape over the entire length, and as shown by a molding 4A along the front pillar 1 in FIG. 1 (B) as a representative, a head 41, downward from substantially the center in the width direction of the head 41. The leg portion 42 extends, and the lips 43 and 44 extend in a folded shape from the leg ends to both sides.

The outer periphery of the windshield 3 is adhered and fixed along the front pillar 1 with an adhesive 5. Reference numeral 50 is a dam that prevents the adhesive 5 from flowing out. The molding 4A is attached by inserting its leg portion 42 into the gap between the front pillar 1 and the peripheral edge of the windshield 3 and pushing the leg end having the lips 43 and 44 into the adhesive 5.

At the lower end of the molding 4A along the front pillar 1, a molding portion 4C for fitting with a lower molding (not shown) is formed. The molding portion 4C has a head 41, legs 42, lips 43 and 44, which are substantially common to the molding 4A, and a thin wall 45 is integrally formed on the front pillar 1 side as shown in FIG. 4 (C). Has been formed. The wall 45 is the head 41,
Leg 42, lip 43 extending to the front pillar 1 side,
It has a shape and dimension that blocks a space 6 [FIG. 1 (B)] between the front pillar 1.

The molding part 4C having the wall 45 is formed by inserting the lower end of the molding 4A into a cavity of a mold for molding the molding part 4C and injecting a synthetic resin material of the same quality as the molding 4A into the cavity. Is formed at the lower end of.

When the vehicle is running, however, the airflow is blocked at the entrance of the gap between the mall 4A and the front pillar 1 by the wall 45 that almost completely blocks the entrance, and the whistle sound is generated at the upper edge of the front window. Is prevented from occurring.

The wall 45 may be formed at an appropriate position in the lengthwise direction of the molding portion 4C, or a plurality of walls may be formed in order to prevent the inflow of airflow more reliably.

The wall 45 that blocks the gap between the front pillar 1 and the molding 4A is a molding 4A along the front pillar 1.
The corner type molding portion 4D for connecting the upper end and the left and right ends of the molding 4B along the upper edge 10 of the front window opening may be used and provided in this. The molding member 4D is molded by inserting the ends of the moldings 4A and 4B into both ends of a mold having a bent cavity and injecting a synthetic resin material into the cavities. in this case,
By providing the wall forming part in the cavity, the mold forming part 4D having the wall 45 is integrally formed. The cross-sectional shape of the wall forming portion is the same as that of the mold forming portion 4C shown in FIG. 1 (C). And
The same operational effect as that of the mold forming portion 4C is obtained.

The wall 45 for blocking the air flow may be provided on either the mold forming member 4C or the corner mold forming member 4D at the lower end of the molding 4A along the front pillar 1, or may be provided on both of them. Since the wall 45 is formed at the same time as the molding, the workability is not impaired at all, and the molding can be formed into an accurate shape that closes the gap between the front pillar 1 and the molding 4A. It is possible to reliably prevent the occurrence.

[0018]

As described above, according to the present invention, the front wind molding is provided at either or both of the lower end of the portion along the front pillar of the front wind molding and the upper end corner portion of the portion of the front wind molding along the front pillar. By forming a wall that blocks the gap between the front pillar and the front pillar, it is possible to reliably and reliably prevent the generation of the whistle sound at low cost.
