The present invention relates to a molding structure for supporting a weather strip of a frame door. More specifically, the door weather strip provided on the frame door is firmly supported on the roof frame of the door, and the door weather strip is mounted on the side of the vehicle body side out panel. The present invention relates to a molding structure for supporting a weather strip of a frame door that enables to form an accurate sealing surface without a separate joint member and a body weather strip installed in an open flange portion.

In general, the vehicle body is provided with a door that opens and closes for passengers to get on and off, such a door is basically adopted a sealing structure to prevent the inflow of water into the cabin during rainy weather and to reduce the draft or wind noise during driving.

To this end, a weather strip is mounted around the open flange of the side-out panel of the body and the front circumference of the door, and the weather strip for this purpose is a body weather strip installed on the side-out panel of the body and a door weather strip installed on the door. It consists of.

However, since the body side center pillar has a smaller bending degree than other parts, the hollow tube of the weather strip is crushed when the body weather strip is installed, thereby reducing the sealing performance.

Accordingly, as shown in FIG. 1, a separate joint member 12 having an inner circumferential surface formed in a curved shape is installed at a corner of the vehicle body side center pillar 10, and is formed around the inner circumference of the frame door 14. The airtight sealing surface with the door weather strip 16 to be installed is secured.

In recent years, as shown in FIG. 2, despite being a vehicle model that applies the frame door 14 among foreign competitive models, the joint member 12 provided at the corner of the center pillar pillar 10 of the vehicle body is removed. By installing a separate molding 18 having a curved inner circumferential surface at a corner of the frame door 14, a structure may be adopted to reduce cost.

That is, the molding 18 installed at the corner portion of the frame door 14 directly faces the corner portion of the body weather strip 20 installed at the center pillar 10 to form a sealing surface.

However, in the case of applying the molding 18 as described above, as shown in Figure 3, by installing a separate clip 22 in the roof frame 14a of the frame door 14, the opening and closing of the door Since the door weather strip 16 installed in the frame door 14 must suppress the deformation caused by the external force acting from the front to the rear along the opening / closing direction of the door, the assembly and economical efficiency according to the additional requirements of the parts There has been a problem accompanied by a decrease.

Accordingly, the present invention has been devised to solve the above-mentioned problems, and while the door weather strip is firmly supported through a molding installed on the roof frame of the frame door, the door weather strip has a body side side panel. The purpose is to be able to form a precise sealing surface without a separate joint member and the body weather strip is installed in the open flange of the.

The present invention for achieving the above object, the body weather strip is installed on the vehicle side side-out panel including a center pillar, the door weather strip is provided on the frame door to form the body weather strip and the sealing surface, and In the molding structure for supporting the weather strip of the frame door comprising a molding provided to the corner of the center pillar to form a sealing surface and the corner of the body weather strip,

The molding may include a curved body part seated at a corner portion between the roof frame and the center pillar frame of the frame door, and a locking protrusion part integrally formed at one end of the body part and seated and coupled to the roof frame. It is formed integrally with the other end of the body portion, characterized in that provided with a mounting portion fixed to the center pillar frame integrally.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

As shown in the figure, the body weather strip 20 is installed along the entire circumference of the open flange portion of the side-out panel 1 of the vehicle body, and the door weather strip 16 along the circumference of the frame door 14. And a molding 18 is installed at a corner of the frame door 14 corresponding to a corner of the center pillar 10 of the vehicle body side side panel 1, and the molding 18 is The airtight sealing surface with the door weather strip 16 is secured.

That is, the body weather strip 20 is installed over the entire circumference of the open flange formed inside the vehicle body side side-out panel 1 including the center pillar 10, and the inner circumference of the frame door 14 is provided. A door weather strip 16 is installed to contact the body weather strip 20 to form a sealing surface. A sealing surface with a corner portion of the body weather strip 20 is installed at a corner of the center pillar 10. Molding 18 is formed to form a.

In this case, the molding 18 has an approximately “a” shape so that the molding 18 is seated at an edge portion that is a coupling portion between the roof frame 14a and the center pillar frame 14b forming the corner portion of the frame door 14. The inner circumferential surface is integrally formed with one end portion of the body portion 18a bent in a curved shape in an arc shape, and is integrally formed on one end of the body portion 18a and is seated and coupled to the roof frame 14a to open and close the door. The door protrusion strip 16 is formed integrally with the other end of the body portion 18a and the locking protrusion 18b for supporting the door weather strip 16 from being pushed backward based on the opening / closing direction of the door to the center pillar frame 14b. It is made of a structure having an integral mounting portion (18c) fixed.

Here, the body portion 18a integrally forms a bent surface 18a ', which is bent inwardly so as to surround the inner surface of the corner portion between the roof frame 14a and the center pillar frame 14b. The molding 18 is more stably installed at the corner portion between the roof frame 14a and the center pillar 10.

In addition, the locking protrusion 18b is inserted into the bottom surface of the door weather strip 16 while being elastically attached to the upper surface portion 14a 'of the roof frame 14a of the frame door 14, and is inserted into the door. It serves to fix the weather strip 16.

In addition, the mounting portion 18c includes a fitting protrusion 18d fastened to the insertion hole 14c formed in the center pillar frame 14b of the frame door 14, so that the molding 18 has the frame. This makes it possible to more firmly support the center pillar frame 14b of the door 14.

Therefore, when the molding 18 is installed at the corner portion between the roof frame 14a and the center pillar frame 14b of the frame door 14 as described above, the molding 18 is the vehicle side side out panel 1. It is possible to form an accurate sealing surface without a separate joint member and the body weather strip 20 is installed in the open flange portion.

In addition, since the locking projection 18b of the molding 18 can firmly support the bottom portion of the door weather strip 16 on the roof frame 14a of the frame door 14, the side when the door is closed. As the contact portion between the out panel 1 and the roof frame 14a of the frame door 14 gradually enlarges, the accompanying external force F (shown in FIG. 4), that is, the roof frame of the frame door 14 The deformation caused by the door weather strip 16 to be pushed backward by the external force acting from front to rear along 14a) can be suppressed.

As described above, according to the molding structure for supporting the weather strip of the frame door according to the present invention, the door weather strip installed on the frame door can be firmly supported without a separate member such as a clip on the roof frame of the door, The door weather strip can form an accurate sealing surface without a separate joint member from the body weather strip installed in the open flange of the vehicle side side out panel.
