Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a window weather strip for attaching a front windshield, a rear windshield, etc. of an automobile to the edge of an opening in a vehicle body in an air- and liquid-tight manner.

The windshield mounting means, which is generally referred to as a "fitting type", is used as shown in FIGS.
A window weather strip 1 is fitted to the window weather strip 1, and the window glass 12 is held by this window weather strip 1.

This window weather strip 1 has a flange fitting groove 2 and a glass fitting groove 3 as shown in FIG. The peripheral edge of the windshield 12 is fitted into the fitting groove 3 to securely fix the windshield 12 to the edge of the opening of the vehicle body.

An outer lip 4 that is in close contact with the surface of the body outer panel 11 is integrally formed on the outer peripheral edge of the weather strip 1, and a center lip 5 and an inner lip 6 are integrally formed on the inside following the outer lip 4. , these lips 4°5.6 are brought into close contact with the surface of the body outer panel 11 to form a seal in multiple stages.

However, since these lips 4, 5.6 and the body outer panel 11 are in line contact, even though they are sealed in multiple stages, the sealing is incomplete and rainwater, etc. seeps through the 2 portions of the flange fitting grooves, causing damage to the vehicle. There was a risk that it might get inside the room.

In addition, the center lip 5 and inner lip 6 are
If the mounting position of the strip 1 deviates from the normal position due to deformation of the vehicle body opening edge flange 10, distortion of the windshield 12, etc., the inner lip 6 of the body outer panel 11 may easily float above the surface of the body outer panel 11. The vicinity of the forming base of the flange portion 11 where the flange portion 11 comes into contact is not exposed to the outside and is not sufficiently coated, so the closeness of the inner lip 6 to this portion is low. There was a problem that made the situation even worse.

In view of this conventional situation, the present invention provides a hollow backing section on the back surface of the outer lip that contacts the body outer panel surface of the weatherstrip, and brings the backing section into surface contact with the body outer panel surface to ensure sealing. Embodiments thereof will be described below in detail with reference to the drawings, in which the same parts as those of the conventional structure are given the same reference numerals.

That is, in the present invention, as illustrated in FIG. 3, a hollow backing portion 7 is integrally formed in a bulging shape on the back surface of the outer lip 4 that comes into contact with the body outer panel 11 surface of the window weather strip 1. .

By bulging the hollow backing part 7 on the back surface of the outer lip 4 in this way, when the windshield 12 is installed, the hollow backing part 7 is crushed as shown in FIG. In close and wide surface contact with the body outer panel 11,
The portion where the outer lip 4 is arranged is far away from the molded base of the vehicle body opening edge flange portion 10, and this portion is carefully coated with a finish coating to enhance the surface smoothness, similar to the panel-membrane surface. Therefore, the closeness of the hollow backing part 7 integrally formed on the back surface of the outer lip 4 with the surface of the body outer panel 11 is very high, and the sealing performance can be further improved.

Furthermore, even if the weather strip 1 deviates from its normal position due to deformation of the vehicle body opening edge flange portion 10, distortion of the windshield 12, etc., the hollow backing portion 7 follows the shape of the body outer panel 11 and is compressed and deformed. Therefore, sufficient sealing performance can be ensured.

Here, by forming the hollow backing part 7 in a bulging shape on the back surface of the ARAClip 4, in order to suppress the outer lip 4 from warping upward due to the sealing reaction force of the hollow backing part 7, the extended base of the outer lip 4 is It is desirable to have a thick wall.

As described above, according to the window weather strip of the present invention, the hollow backing part is integrally formed on the back surface of the outer lip, which is placed in the area with high surface smoothness of the body outer panel. The backing part is crushed over a wide range and comes into surface contact with the body outer panel surface in a highly intimate state, and the backing part also comes into close contact with the body outer panel surface with a relatively high sealing reaction force. The sealing performance is much higher than that of a multi-step seal made by making line contact with the outer panel surface, and since the backing part is hollow, it follows the shape of the body outer panel surface well and can be compressed. Because it deforms, weather damage may occur due to deformation of the flange on the edge of the vehicle body opening or distortion of the windshield.
Even if the strip is deviated from the normal mounting position, the backing portion makes strong surface contact with the body outer panel surface to ensure sealing performance, which has a great practical effect.
