Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automobile seal structure, and more particularly to a seal structure between an opening edge of a vehicle body door opening and an outer periphery of a sashless door.

[0002]

2. Description of the Related Art As shown in FIG. 3, a sashless door vehicle has a door opening edge sealing structure in which the upper edge of the door opening along the roof side 12 is sealed to the upper edges of the front and rear door glasses 11 when the door is closed. A glass seal weather strip 20 is attached to the center pillar 13, and a glass seal weather strip 30 is attached to the center pillar 13 to seal the vertical edges of the front and rear door glasses 11. A door weather strip is attached to contact the half of the door, and the front and rear end portions of the door weather strip are brought into contact with the front and rear lower end portions of the glass seal weather strips 20 and 30 to cover the entire circumference of the door opening edge. It has a basic structure that seals in series. Further, a series of opening trims are attached to the flanges formed on the outer circumferences of the front and rear door openings, and a portion corresponding to the lower half of the door opening edge of the opening trim is brought into contact with the door panel and the door weather strip. A hollow door seal body 40 that forms a double seal is attached.

FIG. 4 (A) shows a front end portion of the glass seal weather strip 20 along the roof side, in which a molded end portion 20B is connected to a lower end of a hollow general portion 20A formed by extrusion. Has been done. The glass seal weather strip 20 has a lip 22 that is pressed against the side edge of the vehicle inner side and the side surface of the opening trim 50.
A series of strips is formed from A to the terminal portion 20B.

On the other hand, the door seal body 40 is a hollow extruded body and is provided along the side surface of the lower half portion of the opening trim 50. The terminal portion 41 of the door seal body 40 and the end portion 23 of the lip 22 are superposed at a position near the door belt line 14 (FIG. 3).

That is, the lip 22 is folded inwardly in an L shape and is pressed against the side surface of the opening trim 50, but the terminal end portion 23 of the lip 22 is formed in a fin shape whose width is widened downward. The portion 23 covers the open end 41 of the door seal body 40.

[0006]

However, FIG. 4 (B) shows the problem to be solved by the invention.
Hollow glass seal weather strip 2 as shown in
0 is pushed by the door glass when the door is closed. In addition,
A mirror placket 18 is generally provided at the front end of the belt line of the door panel. In this case, the lower end of the glass seal weather strip 20 is pushed by the mirror placket 18 as shown in the figure. In conjunction with this, in the terminal portion 20B, the lip end portion 23 moves and floats from the opening trim 50 and the door seal body terminal 41. As a result, the terminal opening of the door seal body is exposed from the interior of the vehicle and spoils the appearance. Further, since the lip end portion 23 does not float, the reaction force against the pushing of the door glass 11 is weakened in the hollow seal portion of the terminal portion 20B, which may deteriorate the sealing property.

Therefore, according to the present invention, the lip end portion 23 is formed.
Of the glass seal weather strip and the door seal body, and the good sealing performance is maintained.

[0008]

According to the present invention, as shown in FIG. 1, a lip 22 of a glass seal weather strip 20 is pressed against a side surface of a door opening trim 50, and a terminating end 23 of the lip 22 causes a door seal body 40 of a door seal body 40 to be closed. In the automobile seal structure for covering the end, ribs 24 are formed on the terminal end portion 23 on the rear surface side of the portion where the pressure contact with the opening trim 50 shifts to the covering of the door seal body 40. It is characterized in that when the seal weather strip 20 is pushed in by the door glass 11, the lip end portion 23 is prevented from being deformed in a floating manner. The ribs 24 can be formed at the same time when the end portion 20B of the glass seal weather strip 20 is formed.

According to the present invention, the connection portion between the front and rear ends of the glass seal weather strip 20 along the roof side 12 and the end of the door seal body 40 and the glass seal weather strip 30 along the center pillar 13 shown in FIG. It can be applied to the connecting portion between the terminal and the terminal of the door seal body 40.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows a front end of a glass seal weather strip 20 shown in FIG.
2 shows an embodiment in which the present invention is applied to a connection portion with a terminal on the front side of the.

As shown in FIG. 1A, the general portion 20A of the glass seal weather strip 20 is an extruded body, and a lip 22 extends from a side surface of a hollow main body 21 on the inner side of the vehicle. A bridge 211 is provided to prevent irregular deformation when pushed by the door glass into the hollow.
Is formed. The terminal part 20B of the molding is connected to the terminal of the general part 20A. The terminal part 20B is the general part 20A.
The tip extends like a fin from the shape extending A. The extension of the general portion 20A is hollow, but no bridge is formed.

The lip 22 extending from the general portion 20A to the terminal portion 20B has a strip shape with a uniform width in the general portion 20A.
The end portion 23 extending from the mold forming portion 20B gradually becomes wider and has a fin shape. The lip 22 including the terminal portion 23 has a substantially C-shaped cross section that curves inward.

As shown in FIGS. 1A and 1B, on the back surface of the lip end portion 23 having a concave shape, the end portion 23 and the side surface of the main body of the molding portion 20B are extended in the lip width direction. Thus, two ribs 24 are formed. Each rib 24 is in the shape of a half-circular plate, and the bottom edge thereof is substantially linear and connects the tip of the lip end portion 23 and one end of the base portion of the main body portion.

The glass seal weather strip 20 is fitted into a retainer 16 provided on the door opening edge 15 along the roof side 12 (FIG. 3), and the terminal portion 20B is located near the door belt line 14 (FIG. 3). Clipped to the body panel.

A flange 17 is formed on the front and rear door opening edges partitioned by the center pillar 13 (FIG. 3), and an opening trim 50 is attached to the flange 17 in series.
