Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an automobile weather strip, and more particularly to an automobile weather strip that seals between an opening/closing body such as a door and a vehicle body.

Conventional technology For example, between a car door and the car body, a weather strip that is in close contact with the car body is provided on the door side, and a hollow weather strip that is in close contact with the periphery of the door is attached to the car body side. There is something.

To explain this example with reference to FIGS. 3 to 5, the door panel l is composed of a door inner panel 2 and a door outer panel 3, and is formed by wrapping the end portion of the door outer panel 3 around the end portion of the door inner panel 2. ing. The tightened portion constitutes the peripheral edge 4 of the door panel 1, and the cooling material 5 prevents water from entering the door panel 1.

On the other hand, reference numeral 6 indicates a sill outer panel of the side sill, and a hollow door weather strip 7 attached to the lower surface of the door inner panel 2 is attached to the upper part of this sill outer panel 6.
are becoming closer together.

Further, a hollow weather strip 8 on the vehicle body side is attached to the upper surface of the lower portion of the above-mentioned crane outer panel 6 and is in close contact with the peripheral edge 4 of the door panel l.

Problems to be Solved by the Invention The double seal structure of the door weather strip 7 and the vehicle body weather strip 8 is advantageous in terms of watertightness, but car wash water is sprayed during car washing. Then, due to the water pressure, the weather strip 8 on the vehicle body is inevitably deformed toward the inside of the vehicle (see the broken line in FIG. 4). Therefore, depending on the pressure of this car wash water, the door weather strip 7 is also deformed, causing water to flow toward the inside of the vehicle. There is a problem that there is a risk of infiltration.

Furthermore, in order to solve the above-mentioned problem, it is possible to increase the reaction force of the weather strip 8 on the vehicle body side, but if this is done, the door closing force becomes large and there is a problem that the door becomes difficult to close. .

SUMMARY OF THE INVENTION Therefore, it is an object of the present invention to provide a weather strip for automobiles that can maintain sufficient watertightness even when car wash water or the like is sprayed onto the weather strip, and does not interfere with the door closing operation.

Means for Solving the Problems An automobile weather strip is attached to the vehicle body side and seals between the vehicle body and the opening/closing body, the weather strip comprising: a hollow seal portion at the periphery of the opening/closing body that is in close contact with the inside of the vehicle; a lip portion that extends to the outside of the vehicle interior of the hollow seal portion and wraps around the peripheral edge of the opening and closing body when the opening and closing body is closed so as to be able to come into close contact with the outside of the vehicle interior;
An easily bendable portion is provided near a portion of the hollow seal portion that comes into contact with the periphery of the opening/closing body.

When the operating opening/closing body is closed, the peripheral edge of the opening/closing body comes into contact with the hollow sole portion.

Then, as the hollow seal part deforms, the bendable part of the hollow seal part curves, and the lip part of the hollow seal part extending outside the passenger compartment is pulled toward the inside of the passenger compartment, and the peripheral edge of the opening/closing body The tip of the lip portion is brought into close contact with the outside of the cabin of the opening/closing body.

Embodiment Hereinafter, an embodiment of the present invention will be described in detail with reference to FIG. 5, with the same reference numerals given to the same parts as in the conventional structure along with the drawings.

In Fig. 1.2, a door panel l as an opening/closing body is composed of a door inner panel 2 and a door outer panel 3, and the door inner panel 2 has a hollow door weather door that is in close contact with a sill outer panel 6 of a side sill as a vehicle body. −
It is the same as the prior art in that the strip 7 is attached and that the end portions of the door outer panel 3 and the door inner panel 2 are wound and tightened to form the peripheral edge 4 of the door panel I.

Here, on the lower upper surface of the sill outer panel 6, specifically, at a position corresponding to the peripheral edge 4 of the bipedal door panel 1,
A weather strip 8 on the vehicle body side is attached.

The vehicle body side weather strip 8 includes a hollow seal portion 9 and a sliding lip portion IO integrally formed with the hollow seal portion 9 and extending to the outside of the vehicle interior.

The hollow seal portion 9 includes a protruding portion 9b that rises from the interior side of the mounting portion 9a and extends toward the peripheral edge 4 of the door panel l, and an outer portion 9c that rises from the outside of the vehicle interior of the mounting portion 9a.
and a bold part 9d that connects the protrusion part 9b and the outer part 9c are made continuous to form a hollow shape,
The joint portion of the holding portion 9d to the outer portion 9c is constituted by an easily bendable portion 9e having a smaller wall thickness (for example, 1/2 the thickness) than the holding portion 9d.

On the other hand, the lip portion IO is formed to extend toward the outside of the vehicle interior along the extending direction of the outer side portion 9c of the hollow seal portion 9, and has a length sufficient to allow the tip portion 10a to be brought into close contact with the outside of the vehicle interior of the door outer panel 3. is set to .

The mounting position of the weather strip 8 on the vehicle body side is set so that the end P of the peripheral edge 4 of the door panel l comes into contact with the easily bendable part 9e of the hold part 9d of the hollow seal part 9 when the door is opened. There is.

According to the structure of the above-described embodiment, when the peripheral edge 4 of the door panel l first comes into contact with the hold part 9d of the hollow roll part 9 when the door is closed, this hold part 9d is supported at the upper part by the tension part 9b. It is pushed into the passenger compartment centering around the junction Q with the bulge 9b.

Then, the easily bendable part 9eh of the hold part 9d is bent and the hold part 9d moves toward the interior of the vehicle, so that the outer part 9C of the hollow seal part 9 and the lip part 10 are bent into the hold part 9d.
is pulled toward the passenger compartment by the lip portion lO.
is deformed while wrapping around the peripheral edge 4 of the door panel 1, and the tip 10a of the lip portion 10 comes into close contact with the door outer panel 3 (see FIG. 2).

As a result, the peripheral edge 4 of the door panel 1 is surrounded by the hold part 9d of the hollow seal part 9 and the lip part 1O.

Therefore, for example, when car wash water is sprayed onto the lip portion 10, the lip portion 10 is pressed in a direction closer to the door outer panel 3, so that high watertightness can be ensured. Therefore, there is no need to increase the reaction force of the weather strip in order to ensure watertightness as in the conventional case, which is advantageous in that the door does not become difficult to close.

In addition, since the seal is wrapped around the peripheral edge 4 of the door panel 1, even if the sealant 5 is unevenly applied and the seal breaks, for example, sufficient sealing performance can be ensured and chipping can be prevented. It is possible to effectively protect the peripheral area, which is exposed to water and is disadvantageous in terms of rust prevention.

It should be noted that the present invention is not limited to the above-mentioned embodiments, and the opening/closing body is not limited to a door panel, but can be applied to door glass of a sun urres door or a glass hatch type door.

As described in detail, according to the present invention, the lip portion wraps around and seals the peripheral edge of the opening/closing body when the opening/closing body is closed, so that even when car wash water or the like is sprayed, the lip remains The part is pressed against the outer surface of the opening/closing body to ensure high watertightness.

Therefore, there is no need to set the reaction force of the weather strip large in order to improve watertightness, unlike the conventional type in which the opening and closing body is brought into close contact with the opening and closing body from the inside, so it is advantageous in that the force required to close the opening and closing body is small. becomes.
