Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a drip seal mounted on the body side of an automobile, in which the liquid tightness and airtightness between the body and the periphery of the door when the door is closed. The present invention relates to a drip seal in which the generation of wind noise is reduced and the ease of closing the door is further improved.

[Prior Art] A description will be given with reference to FIGS. 3 to 5.

FIG. 3 is a schematic front view of the vehicle in which only the door panel is shown by a solid line, 1 is a body panel of the roof part, 2 and 2 are arrows B.
The left and right door panels are designed to open in the direction of. 4 and 5 show the portion A in FIG.

A body panel 1 is used as a conventional structure for a vehicle's drip seal for water and air seals and for reducing wind noise.
Mounted on the side, and in the state where the door is closed, a relatively thick hollow that abuts both the body panel 1 and the door panel peripheral portion 2a so as to seal between the body panel 1 and the door panel peripheral portion 2a. The seal side 8b of the U-shaped mounting portion 8
There is a drip seal 8 which is provided on the upper surface of e and has a tongue piece 8a that abuts against the peripheral edge portion 2a of the door panel and is curved upward on the lateral surface of the U-shaped attachment portion 8e.

[Problems to be Solved by the Invention] Although the conventional drip seal 8 is excellent in reducing wind noise, it contains a contradiction in terms of water and air seals and ease of closing. That is, the greater the rigidity of the seal piece 8b and the tongue piece 8a in order to improve the water and air seal and the better the adhesion, the more difficult it is to close. Specifically, in order to prevent water leakage to the inside even when the body panel 1 is washed with water, or when a heavy rain or storm is encountered during operation and the water flow is impacted from the outside. In addition, the rigidity that does not cause water leakage due to the deformation of the hollow seal piece 8b and the tongue piece 8a even by the impact of the water flow, and the appropriate deformation so as not to create a gap between the surfaces of the door panel 2 and the body panel 1 side. Also, it is necessary to have elasticity to restore if the pressing force is removed. However, in order to ensure rigidity and elasticity so that the door can be closed easily and completely, and to prevent water leakage even when the water stream is impacted, the seal pieces 8b that act independently of each other are provided.
It is difficult with the drip seal 8 having the tongue piece 8a.

The present invention solves this problem and provides a drip seal structure that is simple in structure and easy to install.

[Means for Solving Problems] Description will be given with reference to FIGS. 1 to 3.

The drip seal of the present invention is a drip seal having a U-shaped mounting portion 3e fitted to a substantially horizontal ridge 1a fixed to the body panel 1, in which a tongue piece 3a is provided on the outer surface of the upper surface of the U-shaped mounting portion 3e. The tongue piece 3a is erected so as to be slightly inclined toward the side, and the seal piece 3b extends in a curved band shape so as to form an outer wall from the middle of the inside of the tongue piece 3a, and its tip 3c is formed so as to reach the body panel 1. A vertical side 3d connecting the inner side of the upper surface of the U-shaped mounting portion 3e is provided at a position slightly returned from the tip 3c of the piece 3b to form a hollow portion 3f, and when the door is closed, a seal is formed with the tip of the tongue piece 3a. The upper part of the center of the piece 3b and the upper part of the center of the piece 3b are in contact with the peripheral part 2a of the door panel.

[Operation] When the door panel 2 moves toward the vehicle compartment, first the upper end of the tongue piece 3a is pushed toward the vehicle compartment, and then the central upper portion of the seal piece 3b is pushed downward.

When the tongue piece 3a is pushed toward the vehicle compartment, the connecting portion between the tongue piece 3a and the seal piece 3b is also displaced toward the vehicle compartment.

When the connecting portion between the tongue piece 3a and the seal piece 3b is displaced in the vehicle compartment direction, the oblique side portion 3h of the seal piece 3b is pushed in the Za direction,
The central upper portion of the seal piece 3b is more strongly pressed against the peripheral edge portion 2a of the door panel. Therefore, the sealing property of the central upper portion of the sealing piece 3b is improved.

When the central upper portion of the seal piece 3b contacts the door panel peripheral edge portion 2a, the reaction force from the door panel peripheral edge portion 2a causes the seal piece 3b.
The oblique side portion 3h is pushed in the Zb direction through the central upper portion, the connecting portion between the seal piece 3b and the tongue piece 3a is displaced in the vehicle exterior direction, and the tongue piece 3a is also displaced in the vehicle exterior direction, so that the sealing performance is improved.

[Embodiment] A description will be given with reference to FIGS. 1 to 3.

Reference numeral 1 is a body panel, 1a is a substantially horizontal ridge fixed to the body panel 1, 2 is a door panel, and 2a is a peripheral edge portion of the door panel. Reference numeral 3 denotes a drip seal main body, and a lateral U-shaped mounting portion 3e of the drip seal main body 3 is fitted to the ridge 1a. Reference numeral 3g is a core metal embedded in the U-shaped mounting portion 3d.

A tongue piece 3a is erected on the outer surface of the upper surface of the U-shaped mounting portion 3e so as to be slightly inclined toward the body panel side, and a curved strip shape is formed so that the seal piece 3b forms an outer wall from the middle of the inside of the tongue piece 3a. The tip end 3c extends so as to reach the body panel 1, and at a position slightly returned from the tip end 3c of the seal piece 3b, a vertical side 3 connecting the inside of the upper surface of the U-shaped attachment portion 3e is formed.
d is provided to form the hollow portion 3f, and when the door is closed, the tip of the tongue piece 3a and the central upper portion of the seal piece 3b are both in contact with the door panel peripheral edge portion 2a.

[Effect of the Invention] In the present invention, the tongue piece 3a is integrally formed adjacent to the seal piece 3b in contact with the peripheral edge portion 2a of the door panel.
Bends when the door is closed so as to come into contact with the vicinity of the door panel peripheral edge 2a, and the sealing property of the seal piece 3b is improved by the contact of the tongue piece 3a with the door panel peripheral edge 2a. By contacting the door panel 2 with 3b, the sealing performance of the tongue piece 3a is improved. Therefore, only a small amount of water having a low water pressure that has leaked and passed through the seal piece 3b reaches the tongue piece 3a, which further improves the sealing performance. Therefore, there is little risk of water leakage even during heavy rain or car washing.

Further, the shape is simple, and the manufacturing and mounting are almost the same as the conventional products.
