Abstract

PURPOSE:To obtain a seal structure having a sealing screen excellent in moldability, by which water is prevented from entering from a harness insert slit of a sealing screen. CONSTITUTION:A sealing screen 4 stretched on the compartment side surface of a door inner panel 2 in such a manner as to cover a working hole 6 is provided with a hood part 20 molded by extrusion toward the door inner panel 2 surface side. The lower base 21 of the hood comprises a substantially horizontal center part 22 and side parts 23 inclined obliquely downward in such a manner as to be widened from both ends of the center part 22, wherein a water drip edge 24 is made to swell out on the outer edges of the center part 22 and the side parts 23. A harness insertion slit 12 is formed within a plane surrounded with the outer edges of the center part 22 and the side parts 23 in a side view.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle door sealing device.

[0002]

2. Description of the Related Art FIG. 4 shows an automobile door, which is a door body 1.
Is formed in a closed cross section by a door inner panel 2 and a door outer panel 3, and a sealing screen 4 made of a resin film is attached to the side surface of the door inner panel 2 on the vehicle interior side with an adhesive 5 to The working hole 6 of the inner panel 2 is covered.

A plurality of working holes 6 are provided in the door inner panel 2 for inserting and fixing functional parts 7 in the door such as a power window regulator and a door lock in the door body 1. By doing so, it is possible to prevent dust and water that have entered the door body 1 from the door waist opening 8 from entering the vehicle interior through the work hole 6.

A door trim 9 covers the side surface of the door inner panel 2 on the passenger compartment side. The door trim 9 is provided with a switch unit 10 for controlling the operation of the in-door functional component 7. Functional parts 7
The harness 11 extends over the ceiling screen 2
Are routed through.

[0005]

As described above, in order to route the harness 11 through the sealing screen 4, the sealing screen 4 is provided with a slit for inserting the harness. Various measures have been taken to prevent entry into the passenger compartment.

For example, in the example of FIG. 5, a slit 12 is formed in the ceiling screen 4, and the side surface of the ceiling screen 4 on the side of the door inner panel 2 covers the slit 12 and melts the shutter film 13 at its upper edge portion. It is worn so that water does not enter the interior of the vehicle through the slit 12.

Further, in the example of FIG. 6, the eaves portion 14 is bulging-molded on the ceiling screen 4 toward the door inner panel 2 surface side, and the slit 12 is provided in the substantially horizontal lower bottom portion 15 of the eaves portion 14. Therefore, the water flowing down along the surface of the eaves portion 14 is prevented from flowing into the slit 12 portion.

However, in the former structure, if the shutter film 13 is flipped up and the sealing screen 4 is stuck, the water intrusion prevention function is lost, and in the latter structure, the vehicle body is tilted. When placed in this state, water traveling along the surface of the eaves portion 14 may flow toward the surface of the lower bottom portion 15 and enter the slits 12. In either case, the prevention of water entry cannot be satisfied.

Further, in the former structure, the shutter film 13 must be fusion-bonded after the slit 12 is punched and formed in the sealing screen 4, and in the latter case, the eaves portion 14 is bulged. After that, that is, the eaves 14
After the die molding of the
Since it is necessary to punch and form the slits 12 in each case, the number of processes increases, which is disadvantageous in terms of cost.

Therefore, the present invention provides a sealing device for an automobile door, which can surely prevent water from entering through a slit for applying a harness of a sealing screen, and is excellent in formability and can be obtained in a cost advantage. To do.

[0011]

In a structure in which a working screen is attached to a side surface of a door inner panel on the vehicle interior side and a sealing screen is attached, the eaves portion bulges toward the door inner panel surface side in the sealing screen. The bottom part of the eaves is formed by a substantially horizontal center part and side parts that incline downward from both ends of the center part in a divergent manner. And a slit for harness insertion is provided in the surface surrounded by the outer edges of the center portion and the side portion in a side view.

[0012]

The water flowing down along the eaves surface drops from the draining edge of the outer edge of the lower bottom thereof and is drained away from the eaves surface.

Even when the vehicle body is tilted to some extent, the slit is formed in the surface surrounded by the outer edge of the center portion and the outer edge of the side portion of the lower portion of the eaves. There is no such thing as pouring into the slit.

[0014]

Embodiments of the present invention will now be described in detail with reference to the drawings.

In FIGS. 1 and 2, on the ceiling screen 4 attached to the side surface of the door inner panel 2 on the vehicle compartment side so as to cover the working hole 6, the eaves portion 20 is bulged toward the door inner panel 2 surface side. It is molded.

The lower bottom portion 21 of the eaves portion 20 is composed of a substantially horizontal center portion 22 and side portions 23 which are inclined from the both ends of the center portion 22 in a splayed manner and obliquely downward. A draining edge 24 is formed on the outer edge of the side portion 23 by bulging.

The draining edge 24 is formed in a substantially circular bead shape, but it may be formed in an elongated shape as shown in FIG.

A slit 12 for inserting the harness is provided in the surface surrounded by the outer edges of the center portion 22 and the side portion 23 in a side view.

According to the above-described structure of the embodiment, the water flowing down along the surface of the eaves portion 20 has a draining edge 2 on the outer edge of the lower bottom portion 21 thereof.
4 is dropped as shown by the solid arrow in FIG. 1 and is drained away from the surface of the eaves 20.

Even if the vehicle body is tilted laterally or slightly to the front and rear, the slits 12 are formed in the plane surrounded by the outer edges of the center portion 22 and the side portions 23 of the lower bottom portion 21 of the eaves portion 20. Therefore, the water from the drain edge 24 is shown in FIG.
As shown by the chain line arrow, it does not drip and pour into the slit 12 portion, and therefore water can be reliably prevented from entering through the slit 12.

Although the eaves portion 20 is not shown in the drawing, the eaves portion 20 is molded with a resin film by overheating with a hot press machine.
Since it is formed in the surface surrounded by the outer edges of the center portion 22 and the side portion 23 of FIG. 1 in a side view and can be punched in the direction perpendicular to the surface of the mold, the slit 12 is formed at the same time as the molding of the sealing screen 4. Since it is possible to perform the punching and molding, the secondary processing of the slit 12 is not involved, and the slit 12 can be obtained in cost advantage.

[0022]

As described above, according to the present invention, the lower bottom portion of the eaves portion is composed of the substantially horizontal center portion and the side portions which are slanted downward in a divergent manner from both ends thereof, and these center portions are formed. Formed by swelling the draining edge on the outer edge of the side part,
Further, since a slit for harness insertion is provided in the surface surrounded by the outer edges of the center portion and the side portion in a side view, the water flowing down along the eaves surface is surely drained by these draining edges, There is no dripping to the slit portion, and even if the vehicle body is placed in a slightly inclined state, the slit is in the plane, so the water dripping from the draining edge does not fall onto the slit portion, Therefore, it is possible to reliably prevent water from entering through the slit.

Further, since the slit is in the surface surrounded by the outer edges of the center portion and the side portion, it is possible to perform punching in the direction perpendicular to the surface of the mold when molding the sealing screen. Secondary processing of the slit is not involved, which can greatly contribute to cost reduction.
