DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door weather strip for an automobile, which is attached from a door sash to a rear edge of a door body and seals a space between the door sash and a vehicle body side door opening.

[0002]

2. Description of the Related Art There are door weather strips attached from a door sash portion of a rear door of an automobile to a rear edge of a door body as shown in FIGS.

In this door weather strip 10, a seal lip 2 closely contacting the inner peripheral edge of the vehicle body side door opening 1 is continuously formed from the sash mounting portion 3 to the door body mounting portion 4, and the sash mounting portion 3 At a position outside the seal lip 2 on the vehicle side, a sub lip 6 that extends and curves and closes a parting portion between the door sash 5 and the door opening 1 into a substantially U-shaped cross section is provided. And this door weather strip 10 is a door waist part.
The sub-lip 6 extends to the back of the door waist molding 7 so that the parting part cannot be seen from the outside of the vehicle. Has become.

The door weather strip 10
Since the cross-sectional shapes of the sash mounting portion 3 and the door main body mounting portion 4 change, a set range extending up and down the door waist portion is molded, and the mounting portions 3 and 4 are joined at this portion.

[0005]

In this conventional door weather strip 10, since the sub lip 6 for closing the parting portion extends to the back of the door waist molding 7, the door surface is normally closed when the door is closed. When viewed from the front, the vehicle body panel is not directly visible from the vicinity of the terminal of the door waist molding 7.

However, in the same state, when the area near the end of the door waist molding 7 is viewed from above as shown in FIGS. 7 and 8, a gap is formed between the lower end of the sub lip 6 and the main body of the door weather strip 10. Substantially triangular gap d
The body panel 8 can be seen through. Therefore, the appearance of the vehicle body panel 8 due to the peeping position causes a decrease in appearance quality, and improvement in this respect is desired.

As a remedy, the sub-lip 6 extends further below the door waist molding 7 as shown by a chain line in FIG. 9 (the lower end of the sub-lip at this time is indicated by reference numeral 6 '). However, in order to eliminate the exposure of the vehicle body panel 8 by extending the sub lip 6, the extension length of the sub lip 6 must be considerably increased, and accordingly, the molding range must be increased. (The molded part when the sub lip is not extended is represented by m, and the molded part when the sub lip is extended is represented by m ′). If the mold forming range is widened in this way, not only do the materials used during the mold molding increase and the material cost increases, but also the mold becomes larger and the manufacturing cost of the mold also increases.

Accordingly, the present invention can prevent the appearance of the vehicle body panel from being exposed when looking into the vicinity of the terminal of the door waist molding from above without necessitating the expansion of the molding range, thereby improving the appearance quality. It is an object of the present invention to provide an automobile door weather strip that can achieve both improvement and cost reduction.

[0009]

As a means for solving the above-mentioned problems, the invention according to claim 1 is provided so as to be attached from a door sash to a rear edge of a door body, and a seal lip is provided when the door is closed. A door weather strip for an automobile that is in close contact with the inner peripheral edge of the vehicle body side door opening. In addition to the seal lip, the parting of the door sash and the door opening outside the seal lip is provided on the sash mounting portion. A sub lip is provided to close the portion by bending the portion into a substantially U-shaped cross section, and the sash mounting portion is vertically connected to the door body mounting portion across the back of the terminal portion of the door waist molding on the outside of the vehicle at the door waist position. The lower end of the sub lip extends below the upper end of the vehicle exterior door waist molding, and the lower end of the sub lip faces the vehicle exterior. And a shielding wall is curved.

In the present invention, since the sub lip extends below the upper end of the door waist molding, the vehicle body panel is not visible from the vicinity of the terminal of the door waist molding when the door surface is viewed from the front. At the lower end of the door, a substantially triangular gap between the lower end of the sub lip and the main body of the door weather strip is substantially closed by the shielding wall, so that the door waist is closed. The body panel is not visible even when looking into the vicinity of the mall terminal from above.

According to the second aspect of the present invention, the lower end of the sub lip is further extended below the lower end of the vehicle exterior door waist molding.

In the case of the present invention, since the curved shielding wall is located below the lower end of the door waist molding,
Since the lower end of the sub lip is curved to form the shielding wall, there is no problem that the sub lip is distorted above the door waist molding.

[0013] In the third aspect of the present invention, the lower end of the shielding wall is formed substantially parallel to the vehicle exterior door waist molding.

In the present invention, since the lower end of the shielding wall is formed substantially parallel to the door waist molding, the gap is more completely hidden by the shielding wall when the terminal portion of the door-weight small is viewed from above. .

[0015]

FIG. 1 shows an embodiment of the present invention.
This will be described with reference to FIG.

In the drawings, reference numeral 20 denotes a door weather strip according to the present invention, reference numeral 21 denotes a rear door to which the door weather strip 20 is attached, and reference numeral 22 denotes a door.
This is the door opening on the vehicle body side.

The rear door 21 has a door sash 23, and the rear edge of the door body 24 is
The rear side bulges further rearward than the rear side rising portion, and a door waist molding 25 is attached to the upper side (door waist) of the door body 24. Although the door waist molding 25 is disposed on the inside and the outside of the vehicle with a door glass (not shown) interposed therebetween, only the door waist molding 25 on the outside of the vehicle is shown in the drawing. A door waist molding 25 on the outside of the vehicle extends to a rear end of the door body 24 across a rear rising portion of the door sash 23 and a front surface of the door weather strip 20.

The door weather strip 20 is annularly mounted around the door sash 23 and the door body 24. The sash mounting section 26 is mounted on the door sash 23, and the door body mounting section 27 is mounted on the door body 24. Have different cross-sectional shapes. That is, the sash mounting portion 26 and the door main body mounting portion 27 are both hollow seal lips 28 that are in close contact with the inner peripheral edge of the door opening 22 of the vehicle body.
However, the sash mounting portion 26 has a seal lip 28
In addition, a sub lip 29 that extends and curves and closes a parting portion between the door sash 23 and the door opening 22 in a substantially U-shaped cross section on the vehicle outside of the seal lip 28 is extended.

The general portions of the sash mounting portion 26 and the door body mounting portion 27 are formed by extrusion molding, respectively.
It is joined by molding near the door waist.

As shown in FIG. 3, the molded portion M on the rear side of the door has a sub lip 29 extending near the lower end thereof, and the lower end of the sub lip 29 is closer to the lower end of the door waist molding 25 on the outside of the vehicle. Is also set to be positioned lower by the set distance m. And sub lip 29
Is formed so as to be curved toward the outside of the vehicle, and a portion thereof serves as a shielding wall 30. The lower end of the shielding wall 30 is formed so as to be substantially parallel to the door waist molding 25.

When the door weather strip 20 is mounted on the rear door 21, the lower end of the sub lip 29 on the rear side of the door is disposed below the lower end of the terminal portion of the door waist molding 25, and the shielding wall 30 is positioned at the lower end. A substantially triangular gap (groove) d between the lip 29 and the mounting base of the door weather strip 20 is closed.

Therefore, when the rear door 21 is viewed from the front, the vehicle body panel 3 is positioned near the terminal of the door waist molding 25.
1 and 4, the lower end of the sub lip 29 and the main body of the door weather strip 20 are also exposed when the terminal of the door waist molding 25 is viewed from above as shown in FIGS. Is almost completely closed by the shielding wall 30, so that the vehicle body panel 31 is not exposed. In particular, in the case of this embodiment, since the lower end of the shielding wall 30 is substantially parallel to the door waist molding 25, the inside of the vehicle body panel 31 and the like is not visible even when looking in from a considerably high position.

Further, since the lower end of the sub lip 29 extends below the lower end of the door waist molding 25, the influence of distortion or the like due to the curved shielding wall 30 is less than that of the door waist molding 25 of the sub lip 29. Does not appear on the upper side, and from this point, the appearance quality in the state where the vehicle body is mounted is maintained high.

On the other hand, the door weather strip 20
Since the shielding wall 30 is integrally formed at the lower end of the sub lip 29, as shown by the chain line in FIG.
Compared to a case where a is simply greatly extended downward, the molded portion M can be made smaller. Incidentally, the symbol M 'in the figure indicates the molded portion when the sub lip 29a is simply extended greatly, and the symbol L indicates the conventional length in which the sub lip is set to the length of the back of the door waist molding. 2 shows the lower end position of the sub lip of the sub-lip.

As is apparent from FIG. 1, in the door weather strip 20 according to the present invention, the molded portion M
Can be maintained almost the same as the conventional one in which the sub lip is set to the length to the back of the door waist molding 25.

Therefore, when the door weather strip 20 is employed, the material used in the molding part M can be reduced, and the molding die can be downsized. Can be planned.

The door weather strip 20
Formed the shielding wall 30 by curving the lower end of the sub lip 29 toward the outside of the vehicle.
As compared with the case where the lower end of the lip 9 is simply closed by a wall orthogonal to the longitudinal direction of the lip 29, the increase in the reaction force of the sub lip 29 can be reduced. Therefore, the sub lip 29 can be flexibly deformed and deformed, and there is no problem such as being caught in the door opening when the door is opened and closed.

[0028]

As described above, the invention described in claim 1 is
At a position below the upper end of the door waist molding, the gap between the lower end of the sub lip and the main body of the door weather strip can be almost completely closed by a curved shielding wall. It is possible to reliably prevent the vehicle body panel from being exposed when the terminal unit is looked into from above. Moreover, since it is not necessary to extend the sub lip more downward than the door waist molding, the mold forming range does not need to be greatly expanded, so that the material used in the mold forming is reduced and the forming die is downsized. Can be.

Therefore, according to the present invention, it is possible to achieve both improvement of the appearance quality in a vehicle mounted state and reduction of the cost.

In the present invention, since the lower end of the sub lip is curved toward the outside of the vehicle to form a shielding wall,
The sub lip can be maintained in a more easily bent state as compared with a case where a wall perpendicular to the longitudinal direction is provided at the lower end of the sub lip. Therefore, it is possible to eliminate such a problem that the lip is caught in the door opening when the door is opened and closed due to an increase in the reaction force near the lower end of the sub lip.

According to the second aspect of the present invention, it is possible to prevent the sub lip from being distorted above the door waist molding due to the lower end of the sub lip being curved to form the shielding wall. For this reason, the appearance quality in the vehicle mounted state can be further improved.

According to a third aspect of the present invention, the lower end of the shielding wall is formed substantially in parallel with the vehicle exterior door waist molding.
Since a substantially triangular opening is not formed in the vicinity of the lower end of the sub lip when the terminal portion of the vehicle exterior door waste Samole is viewed from above, the exposure of the vehicle body panel can be more reliably prevented.
