DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a vehicle door seal structure in which a triangular window is fixedly installed at a front end of a door opening of a vehicle body.

[0002]

2. Description of the Related Art As shown in FIG. 5, there is a vehicle structure in which a triangular window 2 fitted with glass 1 is directly fixed to a front end of a door opening 3 of a vehicle body.

As a door seal structure for a vehicle of this kind, a structure as shown in FIGS. 6 and 7 is currently employed. Hereinafter, the door seal structure will be briefly described.

In the drawings, reference numeral 4 denotes a door sash extended from the door body, 5 denotes a front vertical side of the door sash 4, and 6 connects to an upper end of the front vertical side 5. It is an inclined side. Reference numeral 7 denotes a door weatherstrip attached to the door sash 4, and reference numeral 8 denotes a rear window frame of the triangular window 2. The door sash 4 has a closed sash base 10 for holding the main body 9 of the door weather strip 7, and extends from the sash base 10 to the outside of the vehicle to hold an outer peripheral area of a glass run (not shown). It has a cross-sectional structure including a U-shaped glass run locking portion 11. Further, the door weather strip 7 includes a main body 9 having a hollow structure, and a sash molding portion 12 that covers from the upper surface of the glass run engaging portion 11 of the door sash 4 to the vehicle outer surface. The locking portion 11 is hooked on a bent end on the vehicle outside.

The inclined side 6 of the sash molding section 12
Is provided on the upper surface of the portion corresponding to the outer lip extending obliquely upward from the approximate center position in the width direction toward the outside of the vehicle.
3 is in close contact with the inner peripheral surface of the door opening 3. Further, a front edge seal lip 14 is provided at a portion corresponding to the front vertical side 5 of the sash molding portion 12 so as to extend from the outer end to the vehicle body front side. The rear window frame 8 of the window 2 is in close contact with the outer surface of the vehicle. Accordingly, in this door seal structure, the space between the door sash 4 and the door opening 3 is basically sealed by the main body 9 of the door weather strip 7 and separately from the inclined side 6, the door opening 3 and the front part. The space between the vertical side 5 and the rear window frame 8 is auxiliary-sealed by an outward seal lip 13 and a front edge seal lip 14, respectively.

However, in this door seal structure,
As shown in FIG. 7, the root positions of the outward seal lip 13 and the leading edge seal lip 14 are separated in the width direction.
Water droplets a, such as rainwater, flowing along the outward seal lip 13 pass through the gap d to the back side of the front edge seal lip 14, and the water droplet a further flows into the sash molding portion 1.
There is a risk of intrusion into the passenger compartment through a screw hole 15 (a hole for screwing the glass run channel to the door sash) or the like, which is formed in the back of the front edge seal lip 14.

Therefore, in order to cope with this problem, a door seal structure as disclosed in, for example, JP-A-9-240278 has been proposed.

This door seal structure extends in a direction substantially orthogonal to both seal lips at a portion where the outward seal lip and the leading edge seal lip overlap near the connecting corner between the inclined side and the vertical side of the door sash. A blocking wall is formed so as to fill the gap between the two, and the penetration of water droplets on the back side of the leading edge sealing lip is prevented by the blocking wall.

[0009]

However, in this conventional door seal structure, the shut-off wall connecting the outward seal lip and the leading edge seal lip is formed so as to be substantially perpendicular to both, so that when the door is closed. The bending deformation of the outward sealing lip acts to warp the upper end of the leading edge sealing lip to the outside of the vehicle through the blocking wall, thereby deteriorating the sealing performance of the leading edge sealing lip. Another drawback is that water drops flowing along tend to stay on the blocking wall.

Accordingly, the present invention provides a vehicle having a vehicle body fixed triangular window capable of reliably preventing water droplets from entering between the outward seal lip and the leading edge seal lip without causing such a problem. It is intended to provide a door seal structure.

[0011]

Means for Solving the Problems As means for solving the above-mentioned problems, the invention according to claim 1 is characterized in that a triangular window is fixedly installed at a front end of a door opening of a vehicle body, while a triangular window is provided. At the front end, a front vertical side of the door sash adjacent to the rear window frame of the triangular window is extended, and a top surface of the inclined side of the door sash which is continuous with an upper end of the front vertical side is provided in a width direction. An outward seal lip extending obliquely upward from the approximate center position toward the outside of the vehicle and closely contacting the inner peripheral surface of the door opening is provided. A vehicle body fixed triangular window provided with a front edge sealing lip which extends toward the vehicle body front side from the rear side of the rear window frame of the triangular window and is in close contact with the rear window frame, the inclined side of the door sash And the front corner Rutotomoni provided a connection seal lip that connects the front end portion and the front edge Shiruri' flop of the seal lip can,
Move the connecting seal lip from the outward seal lip to the leading edge.
As you approach the seal lip, its root position is on the outside of the car
Progressively displaced, and at the same time the outward inclination
The shape was continuously changed so as to become clear .

In the case of the present invention, water droplets flowing into the front end side of the outward seal lip are blocked by the connecting seal lip and do not go around the back side of the front edge seal lip.
In addition, the shape of the connecting seal lip continuously changes from the front end of the outward seal lip toward the leading edge seal lip, so that the influence of the bending deformation of the outward seal lip when the door is closed affects the leading edge seal lip. In addition, water droplets hardly remain on the upper surface side of the connection seal lip.

[0013] According to a second aspect of the present invention, in the first aspect of the invention, near the front end of the outward seal lip,
A blocking wall for closing the triangular groove formed by the outward seal lip is provided.

In the case of the present invention, water droplets flowing forward along the triangular groove formed by the outward seal lip are blocked by the blocking wall and discharged to the outside of the vehicle.
It is no longer introduced into the connection seal lip.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, an embodiment of the present invention will be described with reference to FIGS.
A description will be given based on FIG.

In the drawings, reference numeral 20 denotes a door opening on the front side of the vehicle body, reference numeral 21 denotes a triangular window fixed to the front end of the door opening 20, and reference numeral 22 denotes a door opening / closing opening. It is a door sash of the front door attached to the. The door sash 22 includes a rear window frame 23 of the triangular window 21.
A front vertical side 24 adjacent to the front vertical side extends to the front end of the door body, and an inclined side 25 connected to an upper side (not shown) is continuously formed at an upper end of the front vertical side 24. Have been.

The door sash 22 has a sash base 28 having a closed cross section for holding the main body 27 of the door weather strip 26, and a U-shape extending to the outside of the sash base 28 and holding the glass runs 30, 30a. It has a cross-sectional structure including a glass run locking portion 29. And
The glass run locking portion 29 has the inclined side 25 and the upper side shown in FIG.
As shown in FIG. 4, the glass run 30 is directly fitted and attached. On the front vertical side 24, the glass run 30a is screwed through the metal glass run channel 31 as shown in FIG.

Further, the door weather strip 26 is provided on the outside of the hollow main body 27 which is in close contact with the door opening 20 of the vehicle body, and covers the upper surface of the glass run locking portion 29 of the door sash 22 from the outer surface of the vehicle. The part 32 is formed integrally. A substantially L-shaped hook-shaped piece 33 is formed at the outer end of the sash molding section 32, and the hook-shaped piece 33 is engaged with a bent end of the glass run locking portion 29.

Then, the inclined side 2 of the sash molding section 32
An outward seal lip 34 extending obliquely upward from the approximate center position in the width direction toward the outside of the vehicle is integrally provided on the upper surface of a portion corresponding to the upper side of the outer seal lip 34. The upper edge of the door opening 20 is closed when the door is closed.
So that it is in close contact with the inner peripheral surface of the. On the other hand, a front edge seal lip 35 that extends almost straight to the front side of the vehicle body is integrally provided at an end of the sash molding portion 32 corresponding to the front vertical side 24 on the vehicle exterior side, The inner edge of the front edge seal lip 35 on the distal end side is in close contact with the vehicle exterior surface of the rear window frame 23 of the triangular window 21.

Here, of the sash molding section 32,
In the vicinity of the portion corresponding to the connecting corner between the front vertical side 24 and the inclined side 25, the shape of the seal lip is continuously changed from the front end of the outward seal lip 34 toward the front edge seal lip 35. A connection seal lip 36 for connecting 34 and 35 is provided. More specifically, the connecting seal lip 36 is such that its root position is gradually displaced outward from the outward seal lip 34 toward the leading edge seal lip 35, and at the same time, the outward inclination angle gradually disappears. The shape has changed. When the door is closed, the edge on the tip side of the connecting seal lip 36 is in close contact with the inner peripheral surface of the door opening 20 together with the outward sealing lip 34. It changes gradually from the inside of the car to the outside of the car, as indicated by a continuous x mark inside. Then, the close contact portion at the tip of the connection seal lip 36 shifts to the rear window frame 23 side of the triangular window 21 from the time when it reaches the end of the door opening 20 on the outside of the vehicle. Department.

In the vicinity of the front end of the outward sealing lip 34, a thin blocking wall 3 for closing a triangular groove 37 continuously formed by the outward sealing lip 34.
8 are formed, and the water droplets a transmitted in the groove 37 toward the front side are blocked by the blocking wall 38 to form the groove 3.
7 to the outside of the vehicle.

Since the door seal structure is constructed as described above, the space between the door sash 22 and the door opening 20 is basically sealed by the main body 27 of the door weather strip 26. The side is further sealed with the door opening 20 by an outward seal lip 34, and the front vertical side 24 is sealed with the rear window frame 23 of the triangular window 21 by a front edge seal lip 35.
Then, at the connecting corner portion of the inclined side 25 and the front vertical side 24, the shape changes continuously from the outward seal lip 34 toward the front edge seal lip 35, that is, from the inside to the outside of the vehicle. The connection seal lip 36 seals between the door opening 20. Therefore, at this connecting corner portion, the water drop a
5 does not wrap around to the back side of the vehicle, and water drops a
Is reliably prevented.

Since the shape of the connection seal lip 36 is twisted from the outward seal lip 34 to the front edge seal lip 35, the door opening 20 is gradually moved from the outward seal lip 34 to the front edge seal lip 35. The contact area with the outer seal lip 3
Since a large amount of water droplets a which are going to flow into this portion along the groove 37 of the fourth portion are discharged to the outside of the vehicle immediately before by the blocking wall 38, the penetration of the water droplets a from this portion is more reliably prevented. .

In the case of this door seal structure, the intrusion of the water droplet a into the back side of the front edge seal lip 35 is such that the connection seal lip continuously twists and changes from the outward seal lip 34 toward the front edge seal lip 35. 36, the deformation of the outward seal lip 34 when the door is closed is unlikely to affect the shape and reaction force of the leading edge seal lip 35, and the sealing performance of the leading edge seal lip 35 is reduced. Never come down.

Further, since the connecting seal lip 36 is continuously twisted from the outward seal lip 34 toward the leading edge seal lip 35, it is difficult for the water droplet a to stay on the upper surface side of the connecting seal lip 36. Also, it is possible to reliably prevent water droplets from entering the vehicle interior.

[0026]

As described above, the invention described in claim 1 is
At the connecting corner between the sloping side of the door sash and the front vertical side,
Rutotomoni provided a connection seal lip of the front end portion and the front edge Shiruri' flop outward seal lip connecting <br/>, the connection seal
Lip from outward seal lip to leading edge seal lip
As it goes, its base position gradually displaces to the outside of the car,
At the same time, the outgoing angle is gradually reduced.
Since the shape is continuously changed , intrusion of water droplets from the outward seal lip to the back side of the leading edge seal lip can be reliably prevented by the connection seal lip, and further, the outward seal lip when the door is closed. Of the leading edge seal lip is less likely to affect the shape and reaction force of the leading edge seal lip, and since water droplets are less likely to remain on the connecting seal lip, the overall door seal performance is reliably improved.

According to a second aspect of the present invention, in the first aspect, near the front end of the outward seal lip,
Since the blocking wall that closes the triangular groove formed by the outward sealing lip is provided, the water droplet flowing into the front side of the outward sealing lip along the groove is blocked by the blocking wall, and the connection sealing lip is formed. This prevents the water droplets from penetrating into the rear side of the leading edge sealing lip.
