Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a sealing structure around an elevating type window panel such as a door window panel or a side window panel, and particularly to a sealing structure around an elevating type window panel such as a door window panel or a side window panel. This invention relates to an improvement in the seal structure around the elevating type window panel.

In recent years, in response to demands for smoother body shapes and reduced air resistance when the vehicle is running, the outer surfaces of door sashes and window frames provided on the vehicle body are flush with the outer surfaces of door window panels and side window panels. One vehicle is provided.

In such a vehicle, the conventional seal structure around the elevating window panel will be explained using the door window panel of a full press door as an example. For example, as shown in FIGS. A glass run 2 is attached to the inner edge of the side of the door sash 1, which is the frame.
It consists of a glass run main body 3 having a U-shaped cross section, and a pair of holding seal lips 4a and 4b protruding from the opening edge of the glass run main body 3 to face each other. The slider 6 fixed to the side of the door window panel 5 is raised and lowered by the pair of holding seal lips 4a and 4b so that its surface is flush with the outer surface of the door frame 1. The weather strip 7 integrated with the glass run 2 is attached, and the weather strip 7 is attached to a hollow weather strip main body 8.
and an outer seal lip 9a and an inner seal lip 9b extending from the weather strip main body 8 to the outside of the vehicle body, and when the door window panel 5 is closed, the outer seal lip 9a
There is one in which the upper end surface of the door window panel 5 is brought into elastic contact with the upper end surface of the door window panel 5, and the upper inner surface of the door window panel 5 is brought into elastic contact with the inner seal lip 9b. In this type, the weather strip 7 having a cross-sectional shape different from that of the glass run 2 is attached to the upper inner edge of the door sash 1. If the weather strip 7 were to have the same cross-sectional shape as the glass run 2, Since the slider 6 must be provided on the upper part of the door window panel 5, the appearance quality and visibility are impaired, and this is taken into consideration to prevent this.
In FIGS. 2 and 3, 10 and 11 are retainers that hold the glass run 2 and weather strip 7, 12 and 13 are screws that fix the retainers 10 and 11 to the door sash 1, and 14 is the door D. This is a door weather strip that keeps the space between the door and the opening edge of the car body watertight. (Refer to Utility Model Application No. 56-143475 for a similar structure.) However, in the conventional sealing structure around the elevating window panel, as shown in Fig. 4, the glass run 2 and weather strip Since each of the inner seal lips 9b has a different cross-sectional shape from the weather strip 7, it becomes troublesome to process the ends of the inner seal lips 9b. It was only stuck to the weather strip main body 8 at the corner C of the door sash 1. Therefore, the groove 15 between the inner seal lip 9b and the weather strip main body 8 is closed like a bag at the corner C of the door sash 1. As a result, for example, if water W such as rainwater or car wash water gets over the sealing surface between the outer seal lip 9a and the upper end surface of the door window panel 5, the water W infiltrates into the groove 15 and gradually It accumulates and eventually overflows from the groove 15, overcomes the sealing surface between the inner seal lip 9b and the door window panel 5, and leaks into the vehicle interior. Furthermore, since the inner seal lip 9b is crushed at the corner C of the door frame 1, the inner seal lip 9b does not come into elastic contact with the upper corner of the door window panel 5, that is, the upper inner surface of the slider 6. If this occurs, there is a risk that the water W that has overcome the sealing surface between the outer seal lip 9a and the door window panel 5 may directly leak into the passenger compartment from the seal failure part of the inner seal lip 9b. be.

Incidentally, such a problem also occurs in the seal structure around the elevating type side window panel.

The present invention has been made in view of the above points, and its purpose is to improve the sealing surface between the weather strip attached to the inner edge of the upper part of the window frame and the upper end surface of the elevating type window panel. To provide a sealing structure around an elevating type window panel which prevents water that has crossed over from leaking into a vehicle interior and improves watertightness around the elevating type window panel.

The gist of the present invention is to displace the inner seal lip of the weather strip attached to the upper inner edge of the window frame along the inner surface of the slider at the corner of the window frame, and Connect to the inner holding seal lip of the glass run attached to the inner edge of the glass run, and connect the groove between the inner seal lip and the weather strip body to the groove between the inner holding seal lip and the glass run body. By doing so, water that has entered the groove on the weather strip side can be discharged into the storage area of the window panel through the groove on the glass run side, and the sealing surface between the inner seal lip and the window panel can be maintained evenly. This is due to the seal structure around the elevating window panel.

Hereinafter, the present invention will be described in detail based on embodiments shown in the accompanying drawings.

In the embodiment shown in FIGS. 5 and 6, a seal structure around the door window panel is shown, and the basic structure of this seal structure is substantially the same as the conventional one, with a glass run on the inner edge of the side of the door frame 1. At the same time, the weather strip 7 integrated with the glass run 2 is attached to the upper inner edge of the door sash 1, and the holding seal lips 4a, 4b of the glass run 2 and the seal lips 9a, 9b of the weather strip 7 are used to close the door sash 1. This is designed to keep the area around the door window panel 5 watertight, but unlike the conventional case, the inner seal lip 9b of the weather strip 7 is attached to the inner surface 6a of the slider 6 at the corner C of the door sash 1. After the glass run 2 is deflected toward the inside of the vehicle,
The groove 15 between the inner seal lip 9b and the weather strip main body 8 communicates with the groove 16 between the inner holding seal lip 4b and the glass run main body 3. I'm starting to do that. It should be noted that the same constituent members as in the prior art are designated by the same reference numerals as in the prior art, and detailed explanation thereof will be omitted here.

Therefore, in the sealing structure around the door window panel according to this embodiment, water W such as rainwater or car wash water can damage the sealing surface between the outer seal lip 9a of the weather strip 7 and the upper end surface of the door window panel 5. If it crosses over, the water W enters into the groove 15 on the weather strip 7 side.
In this state, the groove 15 is in communication with the groove 16 on the glass run 2 side.
The water W inside flows down through the groove 16 on the side of the glass run 2, is discharged into the inside of the door D from the waist opening (not shown) of the door D, and exits the vehicle from a water drain port (not shown) provided in the door D. It is discharged. Therefore, the water W is not stored in the groove 15 on the weather strip 7 side, and the water W does not accumulate in the groove 15 on the weather strip 7 side.
The situation where the seal overflows from inside and goes over the sealing surface between the inner seal lip 9b and the door window panel 5 is eliminated. Also, the inner seal lip 9b
Since it is connected to the holding seal lip 4b on the inner side of the glass run 2, it comes into uniform elastic contact with the upper corner of the door window panel 5, that is, along the upper inner surface of the slider 6.
Watertightness between the inner seal lip 9b and the door window panel 5 is ensured. Therefore, there is no fear that the water W that has passed over the sealing surface between the outer seal lip 9a and the door window panel 5 will leak directly into the vehicle interior from the seal failure portion of the inner seal lip 9b.

In the above embodiment, the present invention is applied to the seal structure around the door window panel 5, but it is not necessarily limited to this, and the present invention is applied to the seal structure around the elevating side window panel. Of course, the invention can be applied. In this case, the glass run 2 and weather strip 7 to which the present invention is applied may be attached to a window frame provided on the vehicle body.

As explained above, according to the seal structure around the elevating window panel according to the present invention, the inner seal lip of the weather strip attached to the upper inner edge of the window frame is attached to the slider at the corner of the window frame. The inner seal lip is connected to the inner retaining seal lip of the glass run attached to the inner edge of the side of the window frame while being displaced along the inner surface, and the inner seal lip is connected to the groove between the inner retaining seal lip and the glass run body. Since the groove between the weather strip and the weather strip body is communicated with each other, water that has entered the groove on the weather strip side can be discharged through the groove on the glass run side into the storage area of the window panel. The sealing surface between the lip and window panel can be maintained evenly,
This improves the watertightness around the elevating window panel, making it possible to reliably prevent water from leaking into the passenger compartment.
