[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sealing structure for an upper part of an automobile.

[0002]

2. Description of the Related Art A description will be given with reference to FIGS. In the figure, 10 is the indoor side, 11 is the outdoor side, 12 is the front side, and 13 is the rear side. Weather strips are mounted on the inner surfaces of the door frame 1a of the front door 1 and the door frame 2a of the rear door 2, respectively. Opposite corner portions 8a and 9a of the weather strips 8 and 9 on the front door 1 side and the rear door 2 side have the same basic structure, and the horizontal portion and the vertical portion of the extruded product are connected by molding. And the hollow seal portions 8b and 9 respectively.
b, seal lips 8c and 9c. Furthermore, the sealing lip 8 of the molding corner 8a on the front door side is provided.
c is slightly projected to the rear door side, and the seal lip 9c of the molded corner 9a on the rear door side is extended forward so as to be in contact with the rear end of the front door side seal lip 8c (see FIG. 5). A vertical lip 9d extends downward along the center pillar 3 (molded integrally with the seal lip 9c). The hollow seal portion 8
b, 9b are the door opening edges of the body including the center pillar 3, the horizontal portion of the seal lips 8c, 9c is the outer surface of the roof panel 6, and the vertical portion (including the vertical lip 9d) is the front and rear inner edges of the door frames 1a, 2a. In each case, they are made to contact each other.

However, since the horizontal portions of the seal lips 8c and 9c are elastically contacted with the outer surface of the roof panel 6 and are in contact with each other (see FIG. 3), the rear door 2
When the door is closed, the horizontal portions of the seal lips 8c and 9c may be turned up to form a gap, resulting in insufficient sealing or impaired appearance, and interference of the seal lips 8c and 9c when opening and closing the door. Therefore, there is a problem that the frictional resistance is increased, and the opening / closing is hindered.

[0004]

The problem to be solved is that the conventional seal structure above the center pillar is
The difficulty lies in the sealability, appearance, and openability of the door.

[0005]

A description will be given with reference to FIGS. 1, 7 to 11. According to the present invention, hollow seal portions 4b and 5b are attached to the front door 1 and the rear door 2, respectively, and elastically contact the door opening edges of the body including the center pillar 3.
A sealing structure at the upper portion of a center pillar comprising a pair of front and rear corner portions of weather strips 4 and 5 provided with sealing lips 4c and 5c which are elastically contacted with the roof panel 6, wherein the sealing lips 4c and 5c are respectively housed. It has a cross-sectional shape that is bent in the shape of a convex inward, extends rearward and forward, and has its upper end elastically contacting the lower surface of the roof panel 6 on the inside of the stepped room, and the upper part of the rear door-side seal lip 5c. Is provided with a protruding portion 5e that protrudes forward beyond the front door-side seal lip 4c, and the front end of the protruding portion 5e is bent in the shape of a vehicle in the room direction, so that the space between the front end side and the front door-side seal lip 4c. A vertical hollow parting seal portion 5 extending downward along the center pillar 3 at the front end of the rear door side seal lip 5c and the lower end of the protruding portion 5e. With couples, it is obtained by extending the vertical hollow parting seal portion 5d to shaped bent portion of Ku of the rear door seal lip 5c.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment will be described with reference to FIGS. 1 and 7 to 11. Reference numerals 1 and 2 denote a front door, rear doors, 1a and 2a denote their respective door frames, and 3 denotes a center pillar. 4 and 5 are the front door side,
The rear door side weather strips 4a and 5a are corner portions of the weather strips 4 and 5 facing each other in front and rear, respectively, and have the same basic structure. It is connected to the vertical portion, and is along the hollow seal portions 4b and 5b which are in elastic contact with the door opening edge of the body including the center pillar 3, the seal lips 4c and 5c which are in elastic contact with the roof panel 6, and along the center pillar 3. A vertical hollow parting seal portion 5d extending downward is provided. More specifically, the seal lips 4c and 5c extend rearward or forward beyond the vertical portions of the corners 4a and 5a, respectively, so that the seal lips 4c and 5c approach each other. The portion protrudes forward beyond the rear end of the front door-side seal lip 4c and is provided with a protruding portion 5e. The seal lips 4c and 5c are formed to have a cross-sectional shape that is bent in the shape of a convex L-shape so as to make the upper ends of the seal lips 4c and 5c elastically contact the lower surface of the roof panel 6 on the indoor side of the stepped portion. The front end of the rear door-side seal lip 5c is bent in the shape of a letter in the room direction to provide a slight gap J of about 1.5 to 2.5 mm between the seal lips 4c and 5c. The vertical hollow parting seal portion 5d is connected to the front end of the rear door side seal lip 5c and the lower end of the protruding portion 5e (molded integrally with the seal lip 5c) to form a vertical hollow parting seal portion 5d.
Is extended to the C-shaped bent portion of the rear door-side seal lip 5c, and extends to the lower front end of the rear door so as to elastically contact the inner surface of the rear end of the front door 1 with the front door 1 closed. It is attached to the outer surface of the stepped portion 2b.

To explain the function, the upper part of the center pillar 3 is covered with the seal lips 4c and 5c, is not seen from the outside, has a good appearance, and is bent in a convex shape toward the room side. As a result, it can flexibly contact the lower surface of the inner step portion of the roof panel 6. Moreover, the front end of the rear door-side seal lip 5c is bent in a V-shape in the room direction so that 1.5 to
Since a slight gap J of 2.5 mm is opened, the rear door side seal lip is opened and closed even when the front end of the rear door side weather strip 5 is moved in and out by opening and closing the rear door 2 with the front door 1 closed. 5c can smoothly advance and retreat without interfering with the front door side seal lip 4c, does not turn over, and is extremely excellent in opening and closing properties. Furthermore, since an integral vertical hollow parting seal 5d having high elasticity is interposed between the rear end of the front door and the front end of the rear door, the sealing performance is extremely excellent.

[0008]

[Effect of the Invention] Since the present invention is configured as described above,
Excellent sealing properties, appearance, and door open / close properties.
