Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a vehicle wind seal that seals the above-mentioned gap with a weather strip so as to prevent water and dust from entering a gap formed between a windshield of a vehicle and an outer panel. Regarding the structure.

[0002]

2. Description of the Related Art Conventionally, as a wind seal structure for a vehicle of this type, there is a structure shown in FIG. 3, for example. In this conventional wind seal structure, an upward flange portion 10e of an outer panel 1e of a vehicle door is provided at a vehicle outside position of a window glass 4e of a vehicle door. As the weather strip 5e, a lower opening having a pair of facing pieces 50e and 51e facing each other is used. In this weather strip 5e, the pair of facing pieces 50e and 51e are the above-mentioned. Flange part 10e
Are fitted in the flange portion 10e so as to sandwich both side surfaces thereof. Further, a part of the reinforcement 9 is overlapped on the flange portion 10e, and a claw piece 12e is formed on the reinforcement 9 and the weather strip 5e is locked to the claw piece 12e. Thus, the weather strip 5e is prevented from coming off.

According to this structure, the weather strip 5e can be mounted substantially by fitting the weather strip 5e to the flange portion 10e from above. Therefore, as compared with the case where the weather strip is attached using the retainer, the assembling and manufacturing work can be facilitated. Further, the parts of the weather strip 5e can be easily replaced.

[0004]

However, in the above-mentioned conventional device, the following problems may occur during actual use.

That is, a window glass 4e for a vehicle
Does not necessarily move vertically exactly in the vertical direction. For example, when the window glass 4e is raised to the top dead center to fully close the window portion of the vehicle door, the window glass 4e is slightly outside the vehicle. In many cases, it moves horizontally so that it bulges toward one side. In this case, the windshield 4e is the opposite piece 50 inside the weather strip 5e.
Press against e.

However, the wind glass 4 as described above
When horizontal movement of e occurs, as shown in FIG. 4, the windshield 4e moves toward the facing piece 5 inside the weather strip 5e.
It is pressed against 0e to press this part. Therefore, due to the pressing force F1 of the windshield 4e, a rotation moment M1 is generated in the weather strip 5e, and the upper portion of the weather strip 5e may be inclined outward of the vehicle body.

Conventionally, although a part of the weather strip 5e is locked to the claw piece 12e of the reinforcement 9, when the rotational moment M1 is generated, the weather strip 5 is still in contact with the claw piece 12e. It was tilted by turning around the locking position as a fulcrum. When the weather strip 5e is tilted in this way, the weather strip 5e is held in the tilted posture unless it is manually corrected.

Therefore, in the past, the appearance of the attached state of the weather strip 5e was very poor. In addition, there is a possibility that the sealing property of the windshield 4e may be deteriorated due to the fact that the mounting posture of the weather strip 5e is not the proper proper posture.

The present invention has been devised under such circumstances, and the weather strip is pressed against the wind glass without causing a problem such as deterioration of workability of attaching the weather strip. The problem is to be able to properly prevent the vehicle from easily leaning toward the outside of the vehicle due to such reasons.

[0010]

DISCLOSURE OF THE INVENTION In order to solve the above problems, the present invention employs the following technical means.

According to a first aspect of the invention of the present application, a lower opening weather having an upwardly facing flange portion of an outer panel provided at a vehicle outside position of a windshield and a pair of facing piece portions facing each other. Equipped with strips,
And this weather strip is a wind seal structure of a vehicle fitted to the flange portion so as to sandwich the flange portion between the pair of opposing piece portions, in the lower part of the outer surface of the flange portion, A convex step portion projecting outward of the vehicle from the flange portion is provided, and the convex step portion is one facing piece portion of the weather strip located on the vehicle outer side of the flange portion. It is characterized by being in contact with or approaching the inner surface of the lower part of.

According to the first aspect of the present invention, the lower portion of one facing piece portion of the weather strip located on the vehicle outer side of the flange portion is provided at the lower portion of the outer surface of the flange portion. The step portion can be brought into contact with the step portion, whereby it is possible to accurately prevent the lower portion of one of the facing strip portions of the weather strip from moving inward of the vehicle. Therefore, even when the weather strip is pressed by the windshield to generate a rotational moment in a direction in which the upper portion of the weather strip falls outward of the vehicle body, the rotation operation of the weather strip is prevented. The Rukoto. That is, the rotational moment that acts to incline the upper portion of the weather strip to the outside of the vehicle body moves the lower portion of one facing piece portion of the weather strip located on the vehicle outside side of the flange portion to the inside of the vehicle. Although acting as a force, the inward movement of the lower part of one of the facing strips of the weather strip can be prevented by the convex step. Therefore, the weather strip does not easily rotate.

As a result, it is possible to prevent the weather strip from inclining due to pressure contact with the windshield glass and to maintain the wind seal in a good condition. Is obtained.

Of course, since the convex step provided on the flange is located inside the facing strip of the weather strip, the convex step can be seen in an unsightly state from the outside of the vehicle. There is no. Further, since the weather strip can be attached to the outer panel by the same fitting method as in the past, there is no problem that the workability of attaching the weather strip is deteriorated.

The invention according to claim 2 of the present application is a weather having a lower opening shape having an upward-facing flange portion of an outer panel provided at a vehicle outside position of a windshield and a pair of facing piece portions facing each other. Equipped with strips,
And this weather strip is a wind seal structure of a vehicle fitted to the flange portion so as to sandwich the flange portion between the pair of opposing piece portions, of the pair of opposing piece portions of the weather strip. A first sealing lip extending from the lower portion to the outside of the vehicle and a second sealing lip extending to the inside of the vehicle are provided at a lower portion of the facing piece portion located on the vehicle outer side of the flange portion. Are provided in a bifurcated shape, and each of the first sealing lip and the second sealing lip is in contact with the surface of the outer panel.

In the invention according to the second aspect, when the weather strip is pressed by the windshield to generate a rotational moment in a direction in which the upper portion of the weather strip is inclined toward the outer side of the vehicle body, the surface of the outer panel is formed. The first sealing lip and the second sealing lip of the weather strip, which are in contact with, will exert a tension force against the rotational moment. In this case, since the second sealing lip extends inward of the vehicle and exerts a tensioning force in a direction substantially the same as the acting direction of the rotational moment, the second sealing lip is In comparison, the tension force acts particularly effectively as a resistance force against the above-mentioned rotational moment.

Therefore, the urging force of each of the sealing lips can prevent the weather strip from rotating, so that the weather strip is tilted unintentionally due to the pressure contact with the windshield. You can get rid of things. As a result, as in the case of the above-mentioned claim 1, the preferable effect that the appearance of the weather strip and the wind seal can be maintained in a good state is obtained.

According to the second aspect of the invention, since the first and second sealing lips of the weather strip are in contact with the surface of the outer panel, the space between the weather strip and the outer panel is reduced. The double sealing can be achieved with the advantage that the mutual sealing function can be enhanced. Further, this claim 2
Also in the invention described in (1), as in the case of the first aspect, the weather strip can be attached to the outer panel by a fitting method, and there is no problem that the workability of attaching the weather strip deteriorates.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, preferred embodiments of the present invention will be specifically described with reference to the drawings.

FIG. 1 is a cross-sectional view of an essential part showing an example of a vehicle wind seal structure to which the present invention is applied, and shows a portion corresponding to a cross section taken along line XX of FIG. FIG. 2 is a schematic front view showing an example of a vehicle door.

First, for the sake of convenience, the schematic structure of the vehicle door shown in FIG. 2 will be described. The vehicle door includes an outer panel 1, an inner panel (not shown) located on the opposite side of the outer panel, and a window 2. The door frame 3 is formed. The window portion 2 can be opened and closed by a window glass 4 which can be raised and lowered by a window regulator (not shown).

The wind seal structure shown in FIG. 1 has a structure in which a weather strip 5 is fitted and attached to an upward flange 10 provided on the upper edge of the outer panel 1.

The flange portion 10 is provided at a vehicle outside position of the window glass 4 which can be raised and lowered, and is formed so as to extend in the vehicle longitudinal direction so as to face the outer surface of the window glass 4. . At the lower portion of the outer side surface 10b of the flange portion 10, a convex step portion 1 that protrudes outward from the vehicle by an appropriate dimension L than the upper portion of the flange portion 10 is formed.
1 are connected in series. The convex step portion 11 can be formed by press-molding a part of the outer panel 1 and is provided over substantially the entire length region of the flange portion 10 in the longitudinal direction.

The inner surface 10a of the flange portion 10 is also
Is provided with a downwardly protruding claw piece 12 for locking the weather strip 5. The claw piece 12 is formed by subjecting the flange portion 10 to so-called cut-and-raising processing and raising a part of the flange portion 10. If such a means is adopted, it is not necessary to additionally provide an extra member such as a reinforcement on the inner side of the outer panel 1 when forming the claw piece 12, and it is easy to form the claw piece 12. In addition, the weight of the vehicle door can be reduced.

The weather strip 5 is made of elastically deformable synthetic rubber or synthetic resin, and has a groove-shaped cross section with an opening 55 formed in the lower portion. The weather strip 5 has a pair of facing pieces 50 and 51 facing each other in such a manner that their upper portions are connected to each other, and the flange portion of the outer panel 1 is located between the pair of facing pieces 50 and 51. The flange portion 10 is fitted from above so as to sandwich 10. The weather strip 5 has the same cross-sectional shape at various points in the longitudinal direction, and is attached over the substantially entire length range of the flange portion 10 in the longitudinal direction.

Inside the pair of opposed piece portions 50 and 51, a core material 52 is embedded which exerts an elastic force in a direction of bringing the opposed piece portions 50 and 51 closer to each other. Also,
The inner surface of each of the facing piece portions 50, 51 has a lip 5 that abuts on both inner and outer side surfaces 10a, 10b of the flange portion 10.
3, 53 are provided. Therefore, these lips 53, 53 are provided on both side surfaces 10a of the flange portion 10,
10b is sandwiched from both the left and right sides with an appropriate force.

The lower end portion 50a of the facing piece portion 50 on the inside of the weather strip 5 is formed in a slightly bent shape, and the claw piece 12 is locked inside the bent lower end portion 50a. There is. In addition, the inside facing piece 50
Bulging portions 54, 54a that come into contact with the outer surface of the window glass 4 are provided on the surface of the bulging portion 5.
A large number of bristles 58 functioning as brushes are appropriately provided on the surface portions of 4, 54a.

On the other hand, the opposing piece portion 51 on the outside of the window glass 4 is arranged so that the lower portion 51a thereof faces the convex step portion 11. Then, these facing piece portions 51
The inner side surface of the lower portion 51a of the
Close to or in contact with each other.

At the tip of the lower portion 51a of the facing piece portion 51, the first sealing lip 5 in a bifurcated shape is formed.
6 and a second sealing lip 57 are provided.
The two sealing lips 56 and 57 are both formed to face obliquely downward, but the first sealing lip 56 is formed to extend to the outside of the vehicle. On the other hand, the second sealing lip 57 is formed so as to extend inward of the vehicle. Each of these sealing lips 56, 57 is in contact with the surface of the outer panel 1 formed in a substantially horizontal plane.

In the wind seal structure having the above structure, since the weather strip 5 is fitted in the flange portion 10 of the outer panel 1, the weather strip 5 can be attached very easily. Further, since the lower portion 51a of the facing piece portion 51 on the outer side of the weather strip 5 and the surface of the outer panel 1 are double-sealed by the two sealing lips 56 and 57, the sealing property of this portion is good. Become. Therefore, even if rust occurs in the cut-and-raised portion of the claw piece 12 of the flange portion 10, it is possible to prevent the rust juice from easily flowing out to the surface side of the outer panel 1. Further, the two bifurcated sealing lips 56, 57 efficiently exert the tension force against the downward force of the outer facing piece portion 51. Therefore, the weather strip 5 is attached to the flange portion 10.
In the case where the weather strip 5 is struck in from above and fitted and mounted, an effect of suppressing an unreasonably large opening of the weather strip 5 (so-called mouth opening phenomenon) can be obtained.

On the other hand, in the above-mentioned window seal structure, when the window glass 4 moves to the vehicle outside (in the direction of arrow a) so as to rise to the top dead center, the window glass 4 Presses the facing piece 50 inside the weather strip 5. Then, a rotational moment M is generated in the weather strip 5 in a direction in which the upper portion of the weather strip 5 falls outward of the vehicle. Specifically, the weather strip 5 has a force that tends to rotate in the direction of the rotational moment M with the locking position between the weather strip 5 and the claw 12 as a fulcrum.

However, the rotation moment M as described above
When this occurs, the first and second sealing lips 56, 57 provided on the lower portion 51a of the facing piece portion 51 come into pressure contact with the surface of the outer panel 1, and these two sealing lips 56, 57 are attached. It exerts a tension force against the rotation moment M. In particular, since the second sealing lip 57 extends inward of the vehicle, the tension force F of the second sealing lip 57 effectively acts as a resistance force against the rotational moment M. Therefore, due to the bulging of the two sealing lips 56, 57, the lower portion 51a of the facing piece portion 51 of the weather strip 5 is prevented from moving inward of the vehicle. As a result, the entire weather strip 5 has the above-mentioned rotational moment M.
It does not rotate in the direction of action of., And is prevented from leaning indefinitely.

Further, for example, when the rotational moment M is very large, the weather strip 5 can be obtained only by the tensioning force of the two sealing lips 56, 57.
It is also assumed that the rotation of can not be prevented. However, in the present embodiment, even if such a situation occurs, the rotation of the weather strip 5 can be prevented. That is, the convex step portion 11 is located inside the facing piece portion 51 on the outer side of the weather strip 5, and the convex step portion 11 is provided.
Since the lower portion 51a of the facing piece portion 51 comes into contact with the above, the lower portion 51a of the facing piece portion 51 is also prevented from moving inward of the vehicle. As a result, the weather strip 5 is prevented from being unduly rotated and tilted due to the rotational moment M, and the weather strip 5 can be maintained in an appropriate posture.

In the above embodiment, the two sealing lips 5 are provided on the facing piece 51 on the outer side of the weather strip 5.
6, 57 and the means for providing the convex stepped portion 11 below the flange portion 10 are used together, and the weather strip 5
However, the present invention does not necessarily need to use the above two means together. For example, when the weather strip 5 is provided with two sealing lips 56, 57, the flange portion 10
It is not necessary to adopt a means for providing the convex step portion 11 on the lower part of the. On the contrary, when the convex step 11 is provided, the weather strip 5 has two sealing lips 56,
The means for providing 57 may not be adopted.

In addition, according to the present invention, the weather strip 5 is used.
The specific configurations of the respective parts such as the outer panel 1 and the outer panel 1 are not limited to the above-described embodiment, and the specific configurations of the respective parts can be variously changed in design. The window seal structure according to the present invention is not necessarily limited to the vehicle door window seal structure configured as a vehicle side door, and may be configured as a back door or a window portion seal structure other than the vehicle door. Of course. Therefore,
The outer panel referred to in the present invention is not limited to the door outer panel that constitutes the vehicle door.
