[Detailed Description of the Invention] Industrial Application Field The present invention relates to a center seal structure for a double-folding rear door.

2. Description of the Related Art In a vehicle equipped with double-folding back doors, there is no pillar in the center of the opening of the vehicle body to which the back door is attached, and therefore the free end of one of the doors is fitted with a weather guard of the other door. The lips are placed in close contact to seal the center partings of both doors. This is the sixth
To explain with reference to Figures 11 and 11, 1 and 2 are doors that are divided into two in the vehicle width direction and are attached to the rear opening 4 of the vehicle body 3 so that they can be opened using a door hinge (not shown), with one door 1 being the first to close. The other door 2 is set as the rear closing side. A weather strip 5 is attached to the entire periphery of the door 2 on the later closing side, while a weather strip 5 is attached to the upper and lower edges of the door 1 on the first closing side to the side edge on the hinge side. 6 is attached in a U-shape on the rear. On the edge of the free end side of the door 1 on the first closing side, a series of sealing edges 9 are formed to extend vertically from the center of the end wall 7a of the door body 7 to the center of the side wall of the door sash 8. By bringing the weather strip 6 of the door 2 on the rear closing side into close contact with this sealing edge 9, the center parting portions of both doors 1 and 2 can be sealed. Further, corner pieces C and P are additionally formed on the upper and lower ends of the weather strip 6 of the door 1 on the first closing side, and the sealing edge 9
These corner pieces C and P are used at the upper and lower end parts of
The corner C portion of the weather strip 5 of the door 2 on the rear-closing side is brought into close contact with the upper part to achieve a seal. This similar structure is shown in, for example, Japanese Utility Model Application Publication No. 61-78017.

Problems to be Solved by the Invention The corner pieces C and P are integrally connected to the ends of the weather strip 6 and have seal plates 10 fixed to the end wall 7a of the door body 7 by clips.
and a seal flange 11 integrally formed to extend sideways from the front edge of the seal plate 10 at substantially the same height as the weather strip 6, and the seal flange 11 and the door 2 on the rear closing side.
The weather strip 5 overlaps with the weather strip 5 and is in close contact with the weather strip 5. However, especially in the lower part of the door, if water penetrates into the close contact area between the seal plate 10 and the side wall 7a, or if water flows down the seal edge 9 and penetrates from the joint with the seal flange 11, the arrow a in FIG. As shown in Figure 2, there was a problem in which water entered the interior of the room, impairing the sense of quality and reliability. Therefore, the present invention provides a center seal structure for a double-folding back door that can thoroughly seal the corner piece part of the lower side of the door and improve the sense of quality and reliability.

Measures to solve the problem Corner pieces are attached to the upper and lower ends of the weather strip, which is attached in a U-shape on the rear side from the lower edge to the hinge side edge of the door on the first closing side. The lower corner piece has a base part that connects to the weather strip terminal, a seal plate that is integrally molded on the end of this base part and is attached to the door end wall, and a height that is the same as the front edge of this seal plate. and a seal flange which is formed integrally with the seal flange to the side and partially overlaps with a seal edge which is formed overhang on the edge of the free end side of the door on the first closing side. A seal lip is integrally molded from the back of the seal flange to the front upper edge of the base to receive the lower end of the seal edge and whose tip is in close contact with the bottom of the door, and this seal lip covers the gutter. In addition, a drainage groove connected to the gutter is formed at the rear edge of the base.

Function Water that permeates the close contact between the seal plate and the end wall of the door, and the close contact between the seal flange and the seal edge is captured by the gutter, flows down from the gutter to the drain, and is drained outside the vehicle. be done.

Embodiment Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings, in which the same parts as those of the conventional structure are denoted by the same reference numerals.

In Figures 1 to 6, the back door is divided into two parts in the vehicle width direction, a door 1 on the front-closing side and a door 2 on the rear-closing side. While the weather strip 5 is attached to the first closing door 1, a weather strip 6 is attached above it from the lower edge to the hinge side edge, and the weather strip is free. Corner pieces C and P are additionally molded on the end side terminals, and a sealing edge 9 is formed overhanging on the edge of the free end of the door, and from these sealing edges 9 to the corner pieces C and P, the rear closing is performed. The basic structure is the same as the conventional one, including the fact that the weather strips 5 of the side doors 2 are brought into close contact to seal the center parting part (see FIGS. 6 to 9). Here, among the corner pieces C and P,
The lower corner pieces C and P are formed wider than the weather strip 6 and have a base portion 15 connected to the end of the weather strip 6, and are integrally molded with the end of the base portion 15 to form a door edge. A seal plate 16 is fixed to the wall 7a from the outside via a retainer plate 14 by a clip (not shown), and a seal plate 16 is integrally formed to extend sideward at the same height from the front edge of the seal plate 16 to the seal edge 9. It consists of a partially overlapping sealing flange 17. Also, from the back of this seal flange 17,
A seal lip 18 is integrally formed over the front upper edge of the base portion 15 to receive the lower end of the seal edge 9 in a bag-like manner and whose tip is brought into close contact with the bottom surface of the door. Further, the base portion 15 has ribs intersecting with the seal lip 15 on its upper surface, in this embodiment two ribs 19, 19, which protrude in the front-rear direction, and these seal lips 18 and ribs 19 form the gutter portion 20. The gutter portion 2 is formed on the rear edge of the base portion 15.
A drain groove 21 that continues to 0 is formed. Since the base portions 15 of the corner pieces C and P are formed wider than the weather strip 6 as described above,
The weather strip mounting shelf of the door body 7 is located on the second
As shown by the broken line in the figure, a portion corresponding to the base portion 15 is formed to be widened. In addition, in this embodiment, a rib 22 is provided on the back surface of the seal plate 16 below the clip insertion hole 16a and projects obliquely in the front-rear direction to further prevent water from entering. We are taking thorough measures to prevent this.

According to the structure of the above embodiment, rainwater, car wash water, etc. are removed from the door end wall 7a of the door 1 on the first closing side and the seal edge 9.
It flows down to the lower corner pieces C and P.
Since the seal flange 17 is integrally molded at the same height as the seal plate 16 and is in close contact with the seal edge 9, most of the water that flows down through the seal edge 9 flows onto the outer surface of the seal flange 17. The water flows down through the top and drains out of the vehicle, but even if some of the water penetrates the close contact area between the seal edge 9 and the seal flange 17, it is captured by the gutter 20 formed by the seal lip 18. . On the other hand, most of the water that flows down the door end wall 7a flows down on the outer surface of the seal plate 16 and is drained out of the vehicle. Even if the water penetrates through the clip insertion hole 16a, the water is first blocked by the rib 22 on the back surface of the seal plate 16 and drained out of the vehicle along the slope thereof. Even if water penetrates over this rib 22, it is captured by the gutter section 20 formed by the aforementioned seal lip 18 and the rib 19 on the upper surface of the base section 15. Especially rib 19 is 2
Since water can be captured in multiple stages by forming strips, water penetration into the weather strip 6 side can be avoided. Even if water infiltrates from either the back side of the seal flange 17 or the back side of the seal plate 16, it can be reliably captured by the gutter portion 20 in this way, thereby preventing water from entering the guide side. ,
The water captured by this gutter section 20 is drained out of the vehicle from the drain groove 21 connected to the gutter section 20 as shown by arrow b in Figure 4, and thorough measures are taken to prevent water from entering around the lower corner pieces C and P. can.

Effects of the invention As described above, according to the invention, the lower corner piece on the free end side of the door on the first closing side is molded with its seal flange stretched out at the same height as the seal plate, so that it partially overlaps with the seal edge. Because of the polymerization, most of the water flowing down the seal edge can be drained by flowing down on the outer surface of the seal flange. Even if water infiltrates the close contact area between the seal flange and the seal edge, or the close contact area between the seal plate and the door end wall, the seal lip formed from the back of the seal flange to the front upper edge of the base part will be removed. and a rib formed on the upper surface of the base in the front-rear direction that intersects with the seal lip.The water can be captured by the gutter formed by the rib formed on the upper surface of the base and drained out of the vehicle from the drain groove on the rear edge of the base, so that water can be drained to the interior side. It is possible to reliably prevent water intrusion, and it is possible to perform a perfect seal around the lower corner piece, further improving quality and reliability.
