Description

TECHNICAL FIELD [0001] The present invention relates to a mounting structure for a vehicle weather strip,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a weather strip for a vehicle, and more particularly to a weather strip mounting structure for a vehicle which simplifies an assembling structure of a weather strip to be mounted on a garnish of a vehicle.

Generally, garnish is a plastic material that is installed on the outside of a vehicle door, a front grill, a decorative plate or a pillar around a rear combination lamp, and is usually attached to the outside of a car body or a cover for interior decoration of a vehicle. So that the appearance of the vehicle is highlighted.

1 and 2 illustrate a conventional garnish mounting structure. As shown in the figure, the garnish 20 mounted on the rear door 10 is provided with a weather strip 30 for blocking the clearance between the vehicle door and the vehicle body The weather strip 30 is composed of a rubber material body 32 and a bracket 34 assembled to the body 32.

The weather strip 30 can be attached to the garnish 20 by being attached to the garnish 20 by welding or the like through the bracket 34 of the plastic material assembled to the body 32. [

In order to fix the weather strip 30 to the garnish 20, a part of the bracket 34 is needed, and a welding process is required, which increases the manufacturing process.

A conventional prior art document discloses a weather strip structure that can be installed on a door inner panel without a retainer in Korean Patent Laid-Open Publication No. 10-2009-0130503 (published on December 24, 2009) There is known a structure in which a clip is installed at regular intervals along contact surfaces and the clip is press-fitted into a hole formed in the door inner panel.

However, in the above-described conventional technique, by using a clip instead of a retainer, this also requires a separate assembled component, which increases the manufacturing cost.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a mounting structure for a vehicle weather strip in which a manufacturing process can be reduced and costs can be reduced by simplifying an assembling structure of a weather strip, will be.

In order to achieve the above object, a mounting structure for a vehicle weather strip according to the present invention is characterized by including a weather strip formed by protruding a latching jaw portion on an inner side surface of a garnish for a vehicle and fitted and fixedly attached to the latching jaw .

Preferably, the engaging step for fixing the weather strip comprises a first engaging jaw protruding integrally from the inner side of the garnish, and a second engaging jaw integrally protruding from the surface perpendicular to the garnish on which the first engaging jaw is formed .

The weather strip further includes a hollow sealing portion in sealing contact with the door panel, a base portion extending from the hollow sealing portion and brought into close contact with the inner bottom surface of the garnish, a first portion formed by extrusion molding on the upper surface of the base portion, And a second engaging surface formed to be tightly fixed to the lower surface of the second engaging jaw.

In addition, the weather strip is provided with a sealing projection for close contact with the door panel at the proximity of the hollow sealing portion, a sealing projection for enhancing the adhesion of the garnish to the end portion of the base portion and a sealing projection for fixing the first engagement projection to the upper side of the first engagement surface And a fixing protrusion which is integrally projected is further formed.

In the mounting structure for a vehicle weather strip according to the present invention, by simplifying the assembling structure of the weather strip, the productivity is improved and the cost is reduced by reducing the manufacturing process.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the structure and operation of a vehicle weather strip mounting structure according to the present invention will be described in detail with reference to the accompanying drawings.

3 is a view showing a mounting surface of a garnish for a vehicle according to an embodiment of the present invention, and FIG. 4 is a cross-sectional side view of a partial cross-sectional view taken along line B-B 'of FIG.

Will be described with reference to Figs. 1 and 3 to 4. Fig. According to a preferred embodiment of the present invention, there is a mounting structure in which the weather strip 120 is fitted and fixedly attached to the garnish 110 having the latching jaw portion 112 formed thereon.

First, the garnish 110 is made of a plastic material and is installed outside the door panel 100 of the vehicle, which can complement the structural rigidity and enhance the appearance of the vehicle.

At least one locking protrusion 112 may be formed on one side of the inner surface of the garnish 110 that is attached to the outside of the door panel 100. Preferably, A first stopping protrusion 112a is integrally protruded from a side surface and a second stopping protrusion 112b is integrally formed on a surface perpendicular to the one surface of the garnish 110 on which the first stopping protrusion 112a is formed Can be formed.

The first and second stopping protrusions 112a and 112b may be integrally formed when the mold of the garnish 110 is manufactured.

The weather strip 120, which is tightly fixed to the engaging jaw portion 112, may be made of a rubber material or urethane, and may be formed in various shapes.

A hollow sealing portion 121 integrally formed from the hollow sealing portion 121 and having a base portion 122 closely attached to an inner bottom surface of the garnish 110, Lt; / RTI >

A first engagement surface 123 is formed on the upper surface of the base portion 122 so as to be fixed to the first engagement stop 112a at the time of extrusion molding. The second engaging surface 124 may be formed to be tightly fixed to the lower surface of the second engaging jaw 112b with a gap between the second engaging jaws 125 and the second engaging jaws 112b.

The weather strip 120 is further provided with a sealing protrusion 126 for close contact with the door panel 100 at the vicinity of the hollow sealing portion 121 and a bottom portion 122, which is a lower side of the sealing protrusion 126, A sealing protrusion 127 for lowering the adhesion of the garnish 110 to the garnish 110 is formed on the end side of the first engaging surface 123 and fixed to the upper side of the first engaging surface 123 so as to fix the first engaging protrusion 112a. The protrusion 128 may be further formed.

According to the present invention having such a configuration, before the garnish 110 is installed on the door panel 100, a weather strip 120 for blocking the gap between the vehicle door and the vehicle body is mounted on the inner surface of the garnish 110 .

First, when the second engagement surface 124 of the weather strip 120 is forcibly pushed into the first engagement step 112a, the second engagement surface 124 of the rubber material and the fixing step 125 are compressed and advanced The second engaging surface 124 is located on the lower surface of the second engaging jaw 112b and at the same time the first engaging surface 123 can be located on the lower surface of the first engaging jaw 112a.

The fixing jaws 125 of the weather strip 120 are positioned and fixed to the intermediate portion between the first and second jaws 112a and 112b so that the fixing protrusions 128 are engaged with the first jaws 112a, So that it is possible to achieve a state in which the movement of the backward movement or the forward movement is restricted.

The sealing protrusion 127 is tightly fixed to the inner bottom surface of the garnish 110 like the base portion 122 and the sealing portion 121 and the sealing protrusion 126 are in close contact with the door panel 100 .

In order to fix the weather strip in the related art, a separate part called a bracket is required for welding with the garnish, and a welding process is required. However, the weather strip 120 of the present invention is not limited to the hooking step 112 ), The number of parts can be reduced, and the process can be simplified.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments.
