[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a mounting structure of an inner seal mounted on a door trim of an automobile.

[0002]

2. Description of the Related Art A conventional inner seal mounting structure will be described below.

FIG. 8 shows a conventional inner seal mounting structure.
As shown in FIG. 9 and FIG. Raised nail 15
Through the mounting hole 7 formed in the garnish 4,
The tip 16 of the claw 15 was bent to fix the inner seal 10 to the garnish 4.

[0004]

However, in the above-mentioned conventional structure, when the garnish 4 is injection-molded by a molding die including a mold 21 and a core 22 as shown in FIG. Since an undercut portion 23 is formed below the hole 7, a slide mechanism must be set in this portion.
However, there is a problem that the cost for manufacturing and maintenance of the device is high.

The present invention solves the above-mentioned conventional problems, and provides an inner seal mounting structure that does not require a slide mechanism, reduces the manufacturing cost of a mold, and facilitates maintenance. With the goal.

[0006]

In order to achieve this object, an inner seal mounting structure according to the present invention has an inner seal along a side surface of a garnish, and a claw provided on one side of the inner seal is provided with a garnish mounting hole. After passing through,
In the inner seal mounting structure in which the claws are bent so that the inner seal is mounted on the garnish,
It has a configuration in which a notch reaching the upper surface of the garnish is formed above the mounting hole.

Preferably, the inner seal mounting structure of the present invention has a structure in which a rib for regulating the vertical movement of the claw is provided on an inner surface of a notch at an appropriate position of the mounting hole.

[0008]

According to this structure, since the notch reaches the upper surface of the garnish, an undercut does not occur in the mold. Therefore, there is no need to provide a slide mechanism in the mold, and the manufacturing cost of the mold is reduced, and maintenance is facilitated.

Further, the vertical movement of the claw can be restricted by the rib of the notch at an appropriate position, and it is not necessary to bend the claw, so that the number of bending steps can be reduced.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIGS. The same components as those shown in the conventional example are denoted by the same reference numerals.

FIG. 1 is a perspective view of a door trim having an inner seal mounting structure according to an embodiment of the present invention, FIG. 2 is an exploded perspective view of the inner seal mounting structure, and FIG. 3 is a sectional view thereof. In the figure, 2 is a trim, 4 is a garnish, and 10 is an inner seal.

An inner seal 10 which is in contact with the door glass and seals rainwater, dust and the like from outside is attached to the upper edge of the door trim 1.

The inner seal 10 includes an inner seal body 11 which is in close contact with the garnish 4, and a plurality of tongue-shaped seal portions 1 are provided in the longitudinal direction on the front side of the inner seal body 11.
3 is formed, and the tip of the seal portion 13 is in contact with a door glass (not shown). Also, the inner seal body 11
A metal core 14 is buried inside, and a plurality of claws 15 are cut and raised at appropriate intervals in the longitudinal direction of the metal core 14, and project from the back side of the inner seal body 11. The tip 16 of the claw 15 is bent at the back of the garnish 4 after the inner seal 10 is attached to the garnish 4.

The garnish 4 has a rectangular cross section, and a trim 2 is attached to an outer surface thereof. Notches 8 for attaching the inner seal 10 are formed in the side wall 6 of the garnish 4 at appropriate intervals corresponding to the claws 15 of the inner seal 10, and the upper part of the notch 8 is formed on the upper surface of the garnish 4. Has reached.

When the inner seal 10 is attached to the garnish 4, the overhang portion 12 at the upper end of the inner seal 10 is brought into contact with the corner of the trim 2, and the inner seal 10 is moved along the side wall 6 of the garnish 4. Then, the claw 15 of the inner seal body 11 is inserted into the notch 8 of the garnish 4, and the tip 16 is bent toward the garnish 4 and fixed.

As described above, since the notch 8 reaches the upper surface of the garnish 4, when the garnish 4 is injection-molded by a mold including a mold 21 and a core 22 as shown in FIG. Since the undercut portion does not occur in the notch 8 of the garnish 4, there is no need to provide a slide mechanism in this portion, and the mold structure can be simplified. Therefore, the manufacturing cost of the mold is reduced, and the maintenance is facilitated.

As another embodiment, as shown in FIGS. 5 and 6, a rib 9 integral with the garnish 4 is provided on the inner surface of a notch 8 at an appropriate position of the garnish 4.
The claw 15 of the inner seal body 11 abuts on the rib 9, and the vertical movement of the claw 15 can be restricted by the rib 9, and the number of places where the claw 15 is bent can be reduced, so that the number of bending steps is reduced. be able to.

Further, as shown in FIG.
Claw 17 for insertion into the inner surface of the overhang portion 12
When the inner seal 10 is attached to the garnish 4, when the inner seal 10 is attached to the garnish 4, the insertion claw 17 is inserted into the notch 8 of the garnish 4. Is folded back at the lower end of the garnish 4, whereby the inner seal 10 is firmly fixed, and can be used to prevent backlash due to the vertical movement of the door glass.

[0019]

As described above, in the present invention, the inner seal is arranged along the side surface of the garnish, and the nail provided on one side of the inner seal is inserted into the mounting hole of the garnish, and then the nail is bent and the inner seal is bent. In the mounting structure of the inner seal adapted to be mounted on the garnish, by forming a cutout reaching the upper surface of the garnish at the upper portion of the mounting hole, an undercut portion does not occur in the forming die, so that a slide mechanism is provided on the forming die. There is no need to provide them, the production cost of the mold is reduced, and maintenance is facilitated.

By providing a rib for regulating the vertical movement of the claw on the inner surface of the notch at an appropriate position of the mounting hole, the vertical movement of the claw can be restricted by the rib, and the claw is bent. Since the number of locations can be reduced, the number of bending steps can be reduced.
