Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to improvements in door seal structures for automobiles.

For example, as shown in FIGS. 1 and 2, a conventional door seal structure includes a door sash section 2 that holds a door glass 1 so that it can be raised and lowered, and a glass run mounting section 3 of this door sash section 2 that is integrally attached to the door sash section 2. A glass run main body 4, an outer surface 1a and an inner surface 1 of the door glass 1 extending from the glass run main body 4;
A glass run 7 includes a door glass seal lip portion 5 which is in elastic contact with the glass run body 4, and a seal portion 6 which is in elastic contact with the edge 1e of the door glass 1 extending from the glass run main body 4; In the conventional example, a drip molding 11 is integrally attached to a joining flange 10 between the roof outer panel 8 and the roof side rail outer 9. In the same figure, 12 is a door weather strip that is integrally attached to the door weather strip attachment part 13 of the door sash part 2 and comes into elastic contact with the roof side rail outer 9 when the door 14 is closed, and 15 is a door weather strip. The welt body side 15a, which has a substantially U-shaped cross section and is fitted to the joint flange portion 17 between the roof side rail outer 9 and the roof side rail inner 16, is integrally molded with the welt body side 15, and is integrally formed with the welt body side 15. A hollow seal lip is shown which is in elastic contact with the inner end 2b.

By the way, in the conventional door seal structure having such a configuration, in order to avoid mutual interference between the door sash section 2 and the drip molding 11 when the door 14 is opened and closed, there is a gap between the door sash section 2 and the drip molding 11. Since the required space 30 was formed, rainwater etc. entered this space 30, and this rainwater further penetrated between the door sash 2 and the door weather strip 12, and between the door sash 2 and the hollow seal lip 15a. Through the
There was a risk that the vehicle would enter the vehicle compartment 18. In addition, since the space 30 is exposed to the outside of the vehicle 19, it not only spoils the aesthetic appearance of the vehicle, but also causes air to enter the space 30 and cause turbulence when the vehicle is running, increasing air resistance and causing turbulence. There was a drawback that it caused wind noise.

Therefore, as shown in Figure 3, the applicant has
The glass run 7 integrally attached to the door sash 2 is connected to the outside of the door sash 2 from a seal 6 that extends from the glass run main body 4 constituting the main body and comes into elastic contact with the edge 1c of the door glass 1. While covering the end 2a, attach the body panel (in this example,
A drip molding seal lip 20 is integrally molded and extends to a position where it makes elastic contact with the outer surface 11a of the drip molding 11 that is integrally attached to the joint flange portion 10) of the roof outer panel 8 and the roof side rail outer 9. We are proposing a door seal structure. According to this door seal structure, the drip molding seal lip 20 comes into elastic contact with the outer surface 11a of the drip molding 11 when the door 14 is closed, and the drip molding 11 bends 11b, the roof side rail outer 9, Since the space 17 surrounded by the door weather strip 12 and the door sash 2 can be closed at a position near the outer end 2a of the door sash 2, the space 30
To prevent rainwater, etc. from entering the inside of the vehicle, to prevent an increase in air resistance and the generation of wind noise caused by turbulence of air entering the space 30 when the vehicle is running, and to prevent the space 30 from being visible from the outside 19 of the vehicle. As a result, it is possible to improve the aesthetic appearance of the automobile, and since there is no gap between the door sash section 2 and the glass run 7, it is possible to prevent rainwater from entering the vehicle interior 18 through the gap. It can be prevented.

However, in the door seal structure configured in this way, the drip molding seal lip 20 may be installed with a misalignment with respect to the door sash portion 2, or the drip molding seal lip 20 may be attached
Even if the drip molding seal lip 20 is installed in the correct mounting position, the drip molding seal lip 20 may fall toward the outside of the vehicle 19, as shown by the imaginary line in FIG. When completed, the extending end 20a of the drip mold seal lip 20
may not come into elastic contact with the outer surface 11a of the drip molding 11, or the strength of its elastic contact may be low, and as a result, there is a risk that rainwater or the like may enter from between the drip molding 11 and the drip molding seal lip 20. Furthermore, since the glass run 7 and the door weather strip 12 are molded separately from the door sash section 2, rainwater that has entered between the drip molding 11 and the drip mold seal lip 20 can leak into the door sash section 2. There was a risk that it would accumulate on the upper surface and enter the vehicle interior 18 through, for example, between the door sash 2 and the door weather strip 12.

In view of these problems, the present invention integrally molds a drip molding seal lip and a door weather strip so that the door sash portion is covered with the drip molding seal lip side. When the door is closed, the drip molding seal lip can make reliable elastic contact with the outside surface of the drip molding, and it also prevents rainwater from entering between the door sash and the door weather strip. The purpose of this invention is to provide a door seal structure that can be used.

Embodiments of the present invention will be described below based on the drawings. Components that are the same as those of the conventional example are given the same reference numerals, and redundant explanation thereof will be omitted.

FIG. 4 is a sectional view of essential parts showing an embodiment of the door seal structure according to the present invention.

As shown in FIG. 4, the glass run main body 4 constituting the glass run 7 is fitted and held within the glass run mounting part 3 of the door sash part 2 that holds the door glass 1 so as to be movable up and down. A hollow seal portion 6 extends from the door glass 1 and comes into elastic contact with the edge 1c of the door glass 1. From this seal portion 6, a door sash portion protrudes from the central portion of the door sash portion 2 in a direction 19 outside the vehicle and extends to a position where the outer surface 11a of the drip molding 11 and the outer surface 1a of the door glass 1 are substantially flush. 2, the outer surface of the drip molding 11 (in this embodiment, the drip molding 1 bent toward the roof side rail outer 9 side)

has been extended. When the door is closed, the drip molding seal lip 20 comes into elastic contact with the outer surface 11a of the drip molding 11 and seals the bent portion 11b of the drip molding 11, the roof side rail outer 9, the door weather strip 12, and the door suspension. The space 30 surrounded by the door sash 2 is closed at a position near the outer end 2a of the door sash 2, thereby preventing rainwater from entering the space 30 and preventing air from entering the space 30 when the vehicle is running. This prevents an increase in air resistance and wind noise caused by intruding turbulence, and improves the aesthetic appearance of the automobile by covering the space 30 so that it cannot be seen from outside the vehicle 19. This is provided to prevent rainwater, etc. from entering the vehicle interior 18 from between the two. Joint part 2 that integrally joins this drip mold seal lip 20 and the seal 6
1 is formed with a fitting part 22 having a substantially root-shaped cross section, and the fitting part 22 is connected to the door sash part 2.
It is fitted into a fitting recess 23 having a substantially U-shaped cross section, which is bent and provided at the outer end 2a of the holder. By fitting and holding the fitting portion 22 into the fitting recess 23, the glass run 7 and the drip mold seal lip 20 are more firmly attached to the door sash portion 2. In addition, door sash part 2
In the door weather strip attachment part 13 formed on the inner side end 2b of the door weather strip, there is provided a weather strip that comes into elastic contact with the outer surface 9a of the roof side rail outer 9 when the door is closed.
A door weather strip 12 for sealing between the door sash portion 2 and the roof side rail outer 9 is fitted and held. A door seal lip mounting portion 24 having a substantially U-shaped cross section is formed continuously between the door weather strip mounting portion 13 and the glass run mounting portion 3. At both ends of this mounting portion 24, Locking portions 4a and 5a extending from the glass run main body 4 side and the door glass seal lip portion 5 side are engaged and fitted so as to sandwich the door seal lip attachment portion 24 from both sides.

The drip mold seal lip 20 and the door weather strip 12 are integrally molded so as to cover the door sash section 2 on the drip mold seal lip 20 side, and when the door is closed. In addition, the extending end 20a of the drip molding seal lip 20 is ensured to come into elastic contact with the outer surface 11a of the drip molding 11, and for some reason the glass run 7 and the door weather strip 1
Even if rainwater or the like remains on the upper surface of the joint part 25 that integrally joins the door sash part 2 and the door weather strip 12, the rainwater etc. is prevented from entering the vehicle interior 18 from between the door sash part 2 and the door weather strip 12, etc. There is.

In such a configuration, when the door glass 1 is closed, the extending end b formed on the door glass seal lip portion 5 first appears on the inner surface 1b of the door glass 1.
comes into elastic contact to seal the gap between the door glass 1 and the door glass seal lip part 5, and then the seal part 6 comes into elastic contact with the edge 1c of the door glass 1, thereby sealing the door glass 1 and the seal lip part 5. 6 will be sealed. On the other hand, when the door is closed, the door weather strip 12 is attached to the outer surface 9a of the outer roof side rail 9, the inner end 2b of the door sash section 2 is attached to the hollow seal lip 15a, and the extension of the drip molding seal lip 20 is attached. The projecting end portions 20a come into elastic contact with the outer surface 11a of the drip molding 11, so that the inside and outside of the vehicle interior are triple-sealed. In this case, the drip mold seal lip 20 that is integrally molded with the glass run 7 and covers the outer end 2a of the door sash section 2 closes the space 30 at a position near the outer end 2a of the door sash section 2. So,
Preventing rainwater, etc. from entering the space 30, preventing an increase in air resistance and wind noise caused by turbulence of air entering the space 30 when the vehicle is running, and preventing the space 30 from being visible from outside the vehicle 19. Since the seal portion 6 and the drip mold seal lip 20 are integrally molded, the door sash portion 2 and the glass run 7 can be It is possible to prevent rainwater and the like from entering the vehicle interior 18. Also, when the door is closed, the drip molding 11

Since the joint 21 between the door glass 1 and the seal portion 6 and the outer surface 1a of the door glass 1 form a substantially flush continuous surface, the aesthetic appearance of the automobile can be improved and wind noise can be prevented. can be achieved.

Further, the drip mold seal lip 20 and the door weather strip 12 are integrally molded so as to cover the door sash section 2 on the drip mold seal lip 20 side. Since the extended end 20a of the drip mold seal lip 20 is always supported so that it does not fall toward the outside of the vehicle 19, the extended end 20a of the drip mold seal lip 20 is It is possible to ensure elastic contact with the outer surface 11a of the drip molding 11. Furthermore, even if rainwater or the like remains on the upper surface of the joint part 25 that integrally joins the drip molding seal lip 20 and the door weather strip 20 for some reason, the rainwater or the like will be transferred to the door sash part 2.
Since it does not enter the gap between the door weather strip 12 and the door weather strip 12, it is possible to prevent the problem of rust on the door sash section 2, especially the door weather strip mounting section 13, and prevent the door weather strip mounting section 13 from getting rusty. , can be prevented from entering the vehicle compartment 18. The rainwater remaining on the upper surface of the joint 25 passes through the gutter 26, which is formed between the joint 25 and the door weather strip 12 and has a generally wedge-shaped cross section, in the longitudinal direction of the vehicle body. Therefore, the problem of rainwater remaining on the upper surface of the joint portion 25 for a long period of time can be prevented.

As shown in FIG. 5, when the door is closed, the outer surface 9a of the roof side rail outer 9 is placed on the joint 25 that joins the drip mold seal lip 20 and the door weather strip 12.
By forming one or more gutter-forming seal lips 27 that come into elastic contact with the gutter, even if rainwater or the like intrudes into the space 30 from the drip molding 11 side for some reason, the rainwater or the like can be transferred to the gutter-forming seal lip 27. Water can be drained in the longitudinal direction of the vehicle body through the gutter waterway 28 formed by the seal lip 27, and the improved sealing performance of the gutter forming seal lip 27 reduces wind leakage noise when the car is running. This can be prevented more reliably than in the embodiment shown in FIG.

Further, in the embodiment shown in FIGS. 4 and 5, the fitting part 22 formed in the glass run 7 is fitted and held in the fitting recess 23 formed in the door sash part 2,
Although the installation strength of the glass run 7 and the drip molding seal lip 20 to the door chassis part 2 is improved, the drip molding seal lip 20
When the door weather strip 12 and the door weather strip 12 are integrally molded, the glass run 7 and the drip mold seal lip 20 are firmly attached to the door sash section 2. For example, as shown in FIG. As shown by the phantom line in the middle, the fitting part 22 extending from the glass run main body 4 can be omitted in the fitting recess 23 formed in the outer end 2a of the door sash part 2 and having a substantially U-shaped cross section. If such a fitting part 22 is not formed, the fitting part 2
Since the work of fitting 2 into the fitting recess 23 can be omitted, the glass run 7,
The workability of attaching the drip mold seal lip 20 and the door weather strip 12 can be improved.

As is clear from the above description, the present invention is one in which a drip molding seal lip and a door weather strip are integrally molded so that the door sash portion is covered with the drip molding seal lip side. This allows the drip molding seal lip to make reliable elastic contact with the outside surface of the drip molding when the door is closed, and prevents rainwater from entering between the door sash and the door weather strip. It can be prevented.
