Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a weather strip that seals between a front pillar and a front door of a vehicle body.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, for example, a weather strip 101 shown in FIG. 2A is known as a weather strip that seals between a vehicle body and a front door to prevent water from entering the vehicle. The weather strip 101 is made of rubber, is formed in a frame shape along the outer periphery of the front door, and is attached to the front door.
[0003]
In the weather strip 101, the front pillar seal portion 102 that seals between the front pillar and the front door of the vehicle body is opposed to the pillar facing the front pillar 120 at the front edge of the front door 110, as shown in FIG. A mounting base 103 that is attached to a step 112 formed on the inner surface of the portion 111 via a retainer 113, and a hollow seal portion 104 that is integrally formed with the mounting base 103 and that is in contact with the front pillar 120. And a lip portion 105 that is integrally formed in parallel with the outside O side of the hollow seal portion 104 and the front end portion 105a contacts the upper edge 110a of the front door 110 and the front pillar 120.
[0004]
A sponge ept portion 106 that partitions the internal space X formed by the hollow seal portion 104, the lip portion 105, and the front pillar 120 when the front door 110 is closed is attached to the hollow seal portion 104 and the lip portion 105 with an adhesive. It is attached. The opt section 106 blocks the traveling wind flowing through the internal space X to prevent wind noise during traveling.
[0005]
[Problems to be solved by the invention]
However, in such a weather strip 101, since the ept portion 106 is attached with an adhesive, the adhesive may deteriorate and the ept portion 106 may be peeled off, and the wind noise during traveling can be stabilized. Could not be prevented.
[0006]
In addition, since the water flowing from the upper part of the weather strip 101 into the internal space X is blocked by the ept part 106 and collected, the water flows down to the door hinge when the front door 110 is opened, and the door hinge is rusted. There is a problem that the operation of the front door 110 may be troubled due to freezing.
[0007]
The present invention has been made in view of such conventional problems, and is capable of stably preventing wind noise during traveling and preventing the occurrence of malfunctions of the front door. The purpose is to provide a strip.
[0008]
[Means for Solving the Problems]
In order to solve the above-mentioned problem, in the weather strip according to claim 1 of the present invention, a mounting base attached to a pillar facing portion of a front door facing a front pillar of a vehicle body, and a hollow and integrally formed with the mounting base A hollow seal portion that abuts on the front pillar, and a lip portion that is integrally formed in parallel with the outside of the hollow seal portion and that has a tip portion that abuts the upper edge of the front door and the front pillar. In the weather strip, an ept portion that divides an internal space formed by the hollow seal portion, the lip portion, and the front pillar when the front door is closed from the hollow seal portion to the lip portion, The end of the lip is on the upper side and the tip of the lip is on the lower side. , It is assumed in which a notch on the outside than the upper edge of the front door to a top proximity than the Epte unit.
[0009]
In such a configuration, the ept portion is not peeled off, and can easily follow the deflection of the hollow seal portion and the lip portion when the door is closed, and can be brought into close contact with the front pillar. Further, the water flowing from the upper part of the weather strip into the internal space can be firmly dammed by the ept part and flowed to the lip part side, and discharged from the notch to the outside.
[0010]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
[0011]
FIG. 1A is a perspective view of a main part of a weather strip 1 showing an embodiment of the present invention, and FIG. 1B is a cross-sectional view showing a main part of the weather strip 1 in an attached state.
[0012]
The weather strip 1 is made of rubber, and has an attachment base 2 attached to a step 13 formed on the inner surface of a pillar facing portion 12 facing the front pillar 21 at the front edge of the front door 11 via a retainer 14. The hollow seal portion 3 that is hollow and integrally formed with the mounting base 2 and abuts against the front pillar 21 is integrally formed in parallel with the outside O side of the hollow seal portion 3, and the front end portion 41 of the front door 11 is formed. The upper edge 15 and the lip portion 4 that contacts the front pillar 21 are provided, and the hollow seal portion 3 and the lip portion 4 are configured to seal between the front pillar 21 and the front door 11.
[0013]
The hollow seal portion 3 to the lip portion 4 are formed with plate-like ept portions 5 that partition the internal space A formed by the hollow seal portion 3, the lip portion 4 and the front pillar 21 when the front door 11 is closed, The ept portion 5 is integrally formed obliquely with the end portion 51 on the hollow seal portion 3 side on the upper side and the tip portion 41 of the lip portion 4 on the lower side.
[0014]
Further, a notch 6 is provided at the front end portion 41 of the lip portion 4 near the upper portion of the ept portion 5 and outside the upper edge 15 of the front door 11.
[0015]
In such a configuration, since the ept portion 5 is integrally formed with the weather strip 1, the ept portion 5 is peeled off because deterioration due to the adhesive does not occur as compared with the case where the ept portion is attached to the weather strip with an adhesive. The durability can be improved.
[0016]
Further, since the ept portion 5 formed in a plate shape is provided obliquely with respect to the weather strip 1, the hollow seal portion is closed when the front door 11 is closed, as compared with the case where the ept portion is provided perpendicular to the weather strip. 3 and the lip portion 4 can easily follow the deflection, and can be brought into close contact with the front pillar 21.
[0017]
Therefore, the function of blocking the wind flowing through the space A formed by the hollow seal portion 3, the lip portion 4, and the front pillar 21 during traveling can be enhanced by the ept portion 5.
[0018]
Further, since the ept portion 5 is in close contact with the front pillar 21, water flowing between the hollow seal portion 3 and the lip portion 4 from above can be firmly dammed. Further, the ept portion 5 is provided obliquely from the hollow seal portion 3 to the tip portion 41 of the lip portion 4 with the end portion 51 on the hollow seal portion 3 side facing upward, and the front door is disposed at the tip portion 41 in the vicinity above the ept portion 5. Since the notch 6 is provided on the outer side of the upper edge 15 of the eleventh portion, the water blocked by the ept portion 5 can flow to the lip portion 4 side and be discharged to the outside from the notch 6 (illustrated by an arrow B). ).
[0019]
Therefore, since the ept portion 5 and the notch 6 do not cause water to accumulate in the space A, water flows down to the door hinge when the front door 11 is opened, and the door hinge rusts, or the door hinge freezes in winter. Can be prevented.
[0020]
Therefore, in weather strip 1 in the present embodiment, it is possible to stably prevent wind noise during traveling and to prevent malfunction of front door 11 from occurring.
[0021]
【The invention's effect】
As described above, in the weather strip according to claim 1 of the present invention, the ept portion is not peeled off, and it is easy to follow the deflection of the hollow seal portion and the lip portion when the door is closed, so that it adheres to the front pillar. Therefore, it is possible to enhance the function of blocking the wind flowing through the internal space during traveling.
[0022]
In addition, water flowing from the top of the weatherstrip to the interior space can be firmly dammed in the ept part and flowed to the lip part and discharged to the outside from the notch, so that water flows down to the door hinge when the door is opened. The door hinge can be prevented from rusting or freezing.
[0023]
Therefore, it is possible to stably prevent wind noise during traveling and to prevent occurrence of malfunctions of the front door.
