DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION This invention is attached to a rear door sash, a rear which is a body panel opening edge and the elastic contact, to seal between the rear door sash body panel opening edge
-Related to door weather strips.

[0002]

2. Description of the Related Art A description will be given with reference to FIGS.
A conventional rear panel which is attached to a body panel opening edge, particularly a rear door sash corresponding to a roof portion and a quarter pillar portion, is elastically contacted with the body panel opening edge 10, and seals between the rear sash 21 and the body panel opening edge 10. As the door weather strip 30, first, FIGS.
As shown, the retainer 2 to the rear door sash 21
2 and a hollow seal portion integrally formed on the vehicle interior of the base portion 31 and elastically contacting the inwardly downward inwardly inclined surface 11 of the inwardly downward stepped body panel opening edge 10 at the inward side of the vehicle. 32, a seal lip 33 integrally formed on the outer side of the base portion 31 and elastically contacting the outer horizontal surface 13 of the body panel opening edge 10 is used.

However, the conventional rear door weather strip 30, when closing the rear door 20, in the roof portion 15 and the rear quarter pillar portion 16, unlike the approach trajectory of the door 20, door 20 by the arrow Z in FIG. 3 In the rear quarter pillar portion 16, the upper surface of the hollow seal portion 32 and the outer horizontal surface 13 of the body panel opening edge 10 do not interfere with the outer horizontal surface 13 of the body panel opening edge 10 in the rear quarter pillar portion 16. Is slightly increased.

[0004] Therefore, in rear corners 17, due to the accuracy of the fell, other parts of the hollow seal portion 32, when closing the rear door 20, as shown in FIG. 4, the corner portion of the hollow seal portion 32 12, there is a problem that the squeezing downward may occur and the sealing performance may be deteriorated.

As a countermeasure, as shown in FIG. 5, the lower surface of the hollow seal portion 32 is brought into direct contact with the indoor side surface of the rear assash 21, or a projection 36 is provided as shown in FIG. Is made to contact the indoor side surface of the rear assass 21 to prevent the hollow seal portion 32 from sneaking in. However, a problem occurs in that the cross section of the rear weather strip 30 becomes large and complicated. .

[0006]

The problem to be solved is that the conventional rear weatherstrip 30 described above.
In other words, when the door 20 is closed in the rear corner portion 17, the hollow seal portion 32 may fall down below the corner portion 12 due to the fall of the hollow seal portion 32, thereby deteriorating the sealing performance.

[0007]

Means for Solving the Problems FIGS. 1 and 7 to 1
The first invention will be described with reference to FIG. The first invention is
Rear quarter from roof 15 through corner 17
-The weather strip that reaches the pillar section 15
The base 31 is fitted to the rear assash 21 via the retainer 22, and is integrally formed on the vehicle interior of the base 31, and is brought into elastic contact with the inwardly downwardly inclined surface 11 of the body panel opening edge 10 on the vehicle interior. the hollow seal portion 32 and integrally formed on the exterior of the base unit 31 Te rear door weather strip 30 smell consisting sealing lip 33 for elastically contacting the vehicle exterior substantially horizontal plane 13 of a body panel opening edge 10, a hollow
A sealing wall g elastically contacting the inclined surface 11 on the sealing portion 32;
Outdoor connecting wall h connecting the seal wall g and the base 31
And the indoor side connecting wall i is formed, and is projected downward so that the indoor side connecting wall i of the hollow seal portion 32 can be brought into linear contact with the indoor side surface of the indoor side hook portion 23 of the retainer 22 at least in the longitudinal direction. To form a convex curved part
Also retainer the boundary between the indoor side connection wall i and the seal wall g.
22 and formed only when the rear door is closed.
The tip of the curved portion is brought into contact with the indoor side hook portion 23,
Also, the hollow seal portion 32 has a rear portion other than the retainer 22.
-Does not touch the door sash 21 .

The second invention will be described with reference to FIG. 1 and FIGS. Instead of bending the indoor side lower surface of the hollow seal portion 32 in the first aspect of the present invention in a convex downward, Li
The indoor side surface of the indoor-side hook portion 23 of the retainer 22 yer door 20 is formed meat Atsutotsu portion 37 as can be at least longitudinally line contact.

[0009]

FIG. 1 and FIG. 7 show an embodiment of the first invention.
This will be described with reference to FIGS. Reference numeral 10 denotes a downwardly inwardly facing stepped body panel opening edge, and 11 denotes a body panel opening edge 1.
The inclined surface of the indoor side lower inward 0, 12 corner portion formed by the inclined surface 11 and the inwardly extending horizontally horizontal plane 14 from its lower end, 20 Riyadoa, 21 rear de <br/> Asasshu, 22 Is a retainer attached to the rear assash 21, and 23 is a hook portion of the retainer 22 on the indoor side.

Reference numeral 30 denotes the body panel opening edge 10 and the rear.
A door weather strip for sealing between the over door sash 21, configured as follows.

Reference numeral 31 denotes a base fitted to the retainer 22. 32, 33 are the inclined surface 11 of the body panel opening edge 10 and the vehicle-side horizontal surface 1 of the inclined surface 11, respectively.
A hollow seal portion and a seal lip elastically contacting the base 3 are formed integrally on the indoor side and the outdoor side of the base portion 31, respectively. Moreover, at least line contact with the interior side surface of the indoor-side hook portion 23 of the retainer 22 of the rear door 20 to the indoor side lower surface of the hollow seal portion 32 (preferably, the range of E of FIG. 10 surface contact) is thereby is able As described above, a convex curved portion is formed by curving downward. Note that a gap T may be provided between the retainer 22 and the retainer 22 in order to avoid deterioration of the insertion workability.

An embodiment of the second invention will be described with reference to FIG. 1 and FIGS. The second invention is
Instead of bending the indoor side lower surface of the hollow seal portion 32 in the first aspect of the present invention in a convex downward, line contact (preferably in the indoor side surface of the indoor-side hook portion 23 of the retainer 22 of the rear door 20, in FIG. 14 The thick convex portion 37 is formed so that the area of F can be brought into surface contact. Other configurations are the same as those of the first invention.

[0013]

[Action] Close rear door 20, when deforming the hollow seal portion 32, in the first invention, the convex curved portion of the interior lower surface of the hollow seal portion 32 is, in the second aspect of the present invention, meat Atsutotsu 37
Are in line contact with at least the indoor side surface of the indoor hook portion 23 of the retainer 22 (preferably, are in surface contact with the range of E in FIG. 10 and F in FIG. 14), so that the hollow seal in the rear corner corner portion 17 is formed. It is possible to prevent the part 32 from falling down, prevent the hollow seal part 32 from sneaking under the corner part 12, and improve the sealing performance. In addition, the configuration as described above can prevent the cross section from being enlarged and complicated.

[0014]

Since the present invention is configured as described above, it is possible to prevent the hollow seal portion 32 from rolling down at the rear corner portion 17 of the hollow seal portion 32 and to sink below the corner portion 12 of the hollow seal portion 32. , Sealing performance can be improved. Moreover, the cross section is as small as before,
Simple.
