Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a seal structure in which a weather strip for center sealing is mounted between a rear edge of a front door glass of an automobile and a front edge of a rear door glass. is there.

2. Description of the Related Art Generally, a weather strip 5 is fitted and held at a door mounting opening edge portion 2 of an automobile 1 shown in FIG. 3 to a retainer 4 provided integrally with a vehicle body side panel 3 as shown in FIG. Therefore, the airtightness of the door glass 6 when the door is closed is maintained. The weather strip 5 is provided with a main lip 5a having a hollow portion and an outer lip 5b having another hollow portion. The outer lip 5b is provided when the door glass 6 rises as shown by an arrow A. The door glass 6 is provided at a position projecting outward from the upper end of the glass 6. On the other hand, 7 shown in FIG. 3 is a weather strip for center seal, and as shown in FIG.
7a and the seal lip 7b where the front door glass 8 is in pressure contact
And a fitting portion 7c through which the rear door glass 9 is inserted, and when the front door glass 8 is pressed, the seal lip 7b is deformed in a direction in which the seal lip 7b is in close contact with the base portion 7a. The watertightness between the weather strips 7 is increased.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention However, in such a conventional vehicle center seal structure, as shown by an arrow B, pressure water is applied from the outside of the vehicle to the boundary portion between the center seal weather strip 7 and the front door glass 8. When it is applied to the front door glass, the pressure water directly hit on the front door glass 8 may enter the vehicle interior from the joint between the seal lip 7b and the front door glass 8, and the water tightness inside and outside the vehicle may deteriorate. There was a problem that it did. Further, in combination with the fact that the thickness of the center seal weather strip 7 is large at the upper end when the door is closed, the windshield 8 and the weather strip 7 are
There is a problem that the step difference when the two overlap with each other becomes large, and a space portion is easily formed between them, and rainwater enters the vehicle interior through this space portion.

Therefore, an object of the present invention is to provide a center seal structure for an automobile, which can solve the problems of the conventional center seal structure for an automobile and improve the watertightness against pressure water from the outside of the automobile. It is a thing.

Means for Solving the Problems In order to achieve the above-mentioned object, the present invention provides, between a rear edge of a front door glass and a front edge of a rear door glass,
A fitting portion through which the front edge portion of the rear door glass is inserted, a base portion extending from the fitting portion to the front door glass side, and folded back to the fitting portion side outside the vehicle from the tip of the base portion, when the door is closed. In a structure in which a center seal weather strip having a seal lip to which the inner surface side of the rear edge of the front door glass is pressed is attached, the upper end of the seal lip of the center seal weather strip is gradually increased from the base side to the tip side. It is formed so as to incline downward, and a rib in the up-down direction that abuts on the inner surface side of the rear end edge of the front door glass when the door is closed is provided at the vehicle outer upper end of the base.

Function When the door is closed, the rear edge of the front door glass is pressed against the seal lip of the center seal weather strip. The upper end of the seal lip gradually inclines downward from the base side to the tip side. The thickness at the upper end of the weather strip for use is reduced and the step difference when the windshield and the weather strip overlap each other is reduced, a space is not formed between them, and the vehicle exterior of the base of the weather strip is reduced. The rib protruding from the upper end is pressed against the rear edge of the front door glass, and the rib receives pressure water that enters from the center seal weather strip when pressure water is applied from outside the vehicle, The double sealing action prevents water from overcoming the sealing lip and entering the vehicle interior.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a vehicle center seal structure according to the present invention will be described in detail below with reference to FIGS. .

Reference numeral 7 denotes a center seal weather strip, which is located between the rear edge of the front door glass 8 and the front edge of the rear door glass 9 and through which the front edge of the rear door glass 9 is inserted. Fitting portion 7c and base portion extending from the fitting portion 7c to the front door glass 8 side
7a and a seal lip 7b which is folded back from the tip of the base 7a toward the fitting portion 7c on the outside of the vehicle and presses against the inner surface of the rear edge of the front door glass 8 when the door is closed.

In this embodiment, the upper end of the seal lip 7b is formed so as to gradually incline downward from the base portion 7a side to the tip end side, and further, the rib 7d in the vertical direction is provided on the vehicle outer upper end portion of the base portion 7a. It is projected. The rib 7d is in a position where it abuts against the inner surface of the rear end edge of the front door glass 8 when the door is closed.

According to this structure, when the front door glass 8 is closed and the front door glass 8 moves in the direction of arrow C shown in FIG. 2, the inner surface of the rear end edge of the front door glass 8 first has the seal lip 7b. It is pressed and deformed to come into contact with the seal lip 7b, and then is pressed against the tip of the rib 7d. Therefore, the upper end portion of the front door glass 8 and the weather strip 7 have a double sealing structure with the rib 7d and the sealing lip 7b, and the moisture that enters through the upper end portion of the front door glass 8 is prevented. It can be shut off completely. Particularly in this embodiment, the upper end of the seal lip 7b is located at the base 7a.
Since the shape is gradually inclined downward from the side to the tip side, the overall wall thickness at the upper end of the center seal weather strip 7 can be reduced when the door is closed, and the front windshield 8 and the weather strip 7 can be reduced. When the two overlap, the difference in level is reduced, and there is no space between the two where rainwater enters. Therefore, the water tightness inside and outside the vehicle when the door is closed is enhanced, and it is possible to completely block the pressure water sprayed from outside the vehicle.

EFFECTS OF THE INVENTION As described in detail above, according to the automobile center seal structure of the present invention, the following operational effects are brought about. That is, when the door is closed, the inner surface side of the rear edge portion of the front door glass first comes into contact with the seal lip of the weather strip for center seal, presses and deforms the seal lip, and press-contacts the rib projecting to the outside of the vehicle. Further, the sealing property between the weather strip for center seal and the front door glass becomes more complete, and it becomes possible to prevent the intrusion of water into the vehicle interior even when the pressure water is sprayed from the outside of the vehicle. In particular, in the case of the present invention, by making the upper end of the seal lip gradually incline downward from the base side to the tip side, the overall wall thickness at the upper end of the center seal weather strip when the door is closed is reduced. This makes it possible to reduce the level difference when the windshield and the weather strip overlap each other, eliminating the space easily formed between the windshield and the weather strip. A center seal structure with extremely good properties can be obtained.
