It also relates to a drip seal structure for automobiles.

[Conventional technology]

Conventionally, as shown in FIG. 5, for example, as shown in FIG. 5, a drip seal A made of synthetic resin or the like has a base part B,
It consists of a sealing part C that is integrally provided on the base part B, and the base part B is provided with an inserted part D that opens on the lower surface, and there is a seal part D inside the inserted part D. , a plurality of locking tongues E are provided protruding from the left and right sides toward the center.

F is a nearly horizontal flange provided at the edge of the opening of a car, and an upstanding part Fa is formed at its free end, and G is a panel door attached to the edge of the opening so as to be openable and closable. , H is the roof panel of the automobile.

Therefore, in this drip seal main body A, the inserted portion D of the drip seal A is inserted into the upright portion Fa of the flange F, and is clamped and fixed by the locking tongues E.

When the panel door G is closed, the interior surface of the panel door G on the passenger compartment side is brought into pressure contact with the sealing portion C to seal between the opening edge and the panel door G, preventing rainwater etc. flowing down from the roof panel H from entering the vehicle interior. That's what I do. Also, when the door is closed, the flange F
A drip channel is formed by the upright part Fa and the roof panel H to collect rainwater, etc. that flows down from the roof panel H and discharge it to the outside of the vehicle body.

In another conventional example, as shown in FIGS. 6 and 7, a drip seal main body A made of synthetic resin or the like has a base portion B and a seal portion integrally provided on the base portion B. The base portion B is provided with an inserted portion D, and within the inserted portion D, a plurality of locking tongues E are provided protruding from the left and right sides toward the center. has been done.
Furthermore, a folded piece F is formed in the seal part B, which is bent toward the base part B side at the mid-abdominal portion and is given elastic force in the left-right direction.

G is a substantially horizontal flange provided at the edge of the opening of an automobile, an upright portion Ga is formed at the free end of this flange G, and H is attached to the edge of the opening so as to be openable and closable. I is a roof panel of a car.

Therefore, in this drip seal main body A, the inserted portion D is inserted into the upright portion Ga of the flange G, and is clamped and fixed by the locking tongues E. At this time, the bent portion Ca of the seal portion C is in contact with the roof panel I of the automobile. When the panel door H is closed, the inner surface of the panel door H on the passenger compartment side is brought into pressure contact with the folding piece F of the seal portion C, sealing between the opening edge and the panel door H, and rainwater J etc. flowing down from the roof panel I is prevented from entering the vehicle. to prevent flooding.

[Problem that the invention attempts to solve]

However, the drip seal body A in Fig. 5
In this case, the seal portion C vibrates while the vehicle is running and generates unpleasant wind noise.

In addition, in FIGS. 6 and 7, the drip seal body A has a dual function as a drip seal and a wind noise seal, but it cannot be expected to have much effect as a drip channel. As shown, when the panel door H was closed, there was a risk that rainwater J, etc. from the roof panel I would travel through the folded piece F of the seal portion C and enter the vehicle interior.

[Means for solving problems]

The present invention was developed to solve the above-mentioned conventional problems, and has a dual function as a drip seal and a seal to prevent wind noise, and also prevents rainwater from entering the passenger compartment. The purpose is to provide a drip seal structure for automobiles that has an excellent effect of preventing intrusion. a straight slope extending from the top;
an elastically deformable lip part having a substantially U-shaped cross section that protrudes toward the roof panel from approximately the middle of the straight slope part and forms a drip channel with the roof panel; and the straight slope part. A drip seal structure for an automobile, comprising a seal part having an arcuate cross section that elastically deforms when pressed against the inner surface of the door facing the passenger compartment, which is formed by folding the tip of the door back to the roof panel side and the opposite side at the folding part. It is in.

〔Example〕

The configuration of the present invention will be explained in Figures 2 to 4 below.
A detailed description will be given based on an embodiment shown in the drawings. Furthermore, Fig. 2 is an enlarged cross-sectional view taken along the - line in Fig. 1, Fig. 3 is a cross-sectional view of the same part as Fig. 2 when the panel door is closed, and Fig. 4 is an enlarged cross-sectional view of the automotive drip seal structure. .

In the figure, 1 is a drip seal made of synthetic resin, and as shown in FIG.
A straight inclined part 3 extends obliquely from the fixing part 2 toward the roof panel (right side in the figure), and a substantially U-shaped cross section protrudes from approximately the middle of the straight inclined part 3 toward the roof panel. and a sealing portion 5 having an arcuate cross section formed by folding the tip of the straight inclined portion 3 at a folding portion 5a on the side opposite to the roof panel (left side in the figure).

Reference numeral 6 denotes an insertion part formed in the fixing part 2 to be inserted into the flange of the vehicle body, and the insertion part 6 is opened downward.
Inside, a plurality of locking tongues 7 are protruded from both left and right sides and extend diagonally upward toward the center.

8 is the body of the car, 9 is the roof panel, 10
1 is a panel door that opens and closes an opening in the vehicle body 8; 11 is a substantially horizontal flange provided at the edge of the opening; an upright portion 11a is formed at the outer end of the flange 11;

The drip seal 1 is disposed at the opening edge of the vehicle body 8 with its fixing part 2 facing down and the lip part 4 facing the roof panel 9 side. Then, the insertion part 6 of the fixing part 2 is inserted into the upright part 11a of the flange 11 provided at the edge of the opening, and the drip seal 1 is clamped from the left and right with the locking tongues 7 provided inside.
is fixed to the vehicle body 8. At this time, since the free end side 4a of the lip portion 4 comes into contact with the roof panel 9,
Straight inclined portion 3 extending inclined toward the roof panel 9 side
resists the elasticity of the roof panel 9 and the opposite side,
That is, the drip seal 1 is pressed in the direction of the panel door 10, and as a result, the drip seal 1 is attached to the vehicle body 8 with the folded portion 5a of the seal portion 5 being pushed out in a direction away from the roof panel 9.

Therefore, when the panel door 10 is closed, as shown in FIG.
At the same time, the lip portion 4 is bent at the midsection to form a seal between the opening edge of the vehicle body 8 and the panel door 10, thereby preventing rainwater etc. flowing down from the roof panel 9 from entering the vehicle interior. ing.

Next, when the panel door 9 is closed, the restoring force of the lip portion 4 causes the bent portion 5a of the seal portion 5 to separate from the roof panel 9, and rainwater etc. from the roof panel 9 is removed. It falls and is accommodated in the lip part 4 as a drip channel, and is prevented from entering the vehicle interior. Therefore, if a drainage port is provided at an appropriate position in the lip portion 4,
Collected rainwater and the like can be easily drained outside the vehicle.
