Description

[Detailed explanation of the invention] This invention relates to automobile weather strips.
In particular, the present invention relates to a weather strip that seals between a side window glass that moves up and down and an outer panel.

Taking automobiles, particularly passenger cars, as an example, weather strips are provided in side doors to provide a seal between the door outer panel and the door glass, and in side panels to provide a seal between the outer panel of the side panel and the side window glass.

Conventional weather strips, for example, are
As seen in Japanese Patent No. 66815, it consists of a base portion fixed to the outer panel, and a lip portion that is flexibly deformed from the base portion via a hinge portion and comes into contact with the window glass. In conventional weather strips, the center of the hinge of the flexibly deformable lip is located close to the window shoulder of the outer panel. That is, the center of the hinge is set inside the door pocket formed by the window glass and the panel window shoulder or at the entrance position of the door pocket. However, recently, in order to reduce running resistance during high-speed driving, prevent wind noise, and reduce fuel consumption, proposals have been made to make the side windows flush with the surface of the vehicle body. For example, if it is a side window with a sash,
In the case of side windows for non-slip, hard-covered vehicles, it has been proposed to reduce the gap between the current window glass and the window shoulder and bring the side windows closer to the outside surface of the vehicle. In the case of such a structure, the length of the lip portion of the conventional weatherstrip inevitably becomes short. For this reason,
As the window glass moves up and down, there is a possibility that the lip part gets wrapped up in the door pocket part, and since the bending deformation is small, there is a problem that the up and down movement of the window glass becomes difficult (hard) and the sealing performance deteriorates.

This idea aims to solve the above-mentioned problems by shifting the center of the hinge of the lip toward the outside of the vehicle interior, making the lip longer, making it possible to move the windshield up and down more easily, and improving the sealing performance. This provides a weather strip with even better performance.

The present invention will be explained based on the embodiment shown in FIGS. 2 and 3.

FIG. 2 is a sectional view of a main part taken along line A--A in FIG. 1, and shows a single seal as the first embodiment.

A window glass 2 of an automobile door 1 moves up and down within a door pocket 5 formed by an inner panel 3 and an outer panel 4. The weather strip 6 seals between the window glass 2 and the outer panel 4, and prevents rainwater and the like from entering the door pocket 5.

The weather strip 6 made of rubber or the like has a base 6a that is in contact with the bent vertical surface 7a of the window shoulder 7 of the outer panel 4, and a base 6a that extends from the upper end of the base 6a along the top surface 7b of the window shoulder 7 to the outside, that is, to the passenger compartment. It consists of an extension part 6b that extends outwardly, and a lip part 6c that extends obliquely upward from the end of the extension part 6b and comes into contact with the window glass 2. The lip portion 6c is formed to be easily flexible, and its hinge point is at the end of the extension portion 6b. In this way, the hinge point of the lip portion 6c is not provided near the entrance of the door pocket 5, and the door pocket 5 is
Since the lip portion 6c is set a certain distance outward (for example, about 10 mm outward) from the entrance of the lip portion 6c, the length of the lip portion 6c can be increased to a certain extent. Therefore, it can be flexibly fitted to the two sides of the window glass, further improving sealing performance.

In the weather strip 6, reference numeral 8 denotes a metal core having a dogleg-shaped cross section and embedded inside the base portion 6a and the extension portion 6b. Further, a resin clip 9 integrally molded approximately at the center of the weather strip 6 and the base 6a is attached to the bent vertical surface 7a of the window shoulder 7.
This is for fixing the weather strip 6 by fitting it into a mounting hole (one or more) drilled in the weather strip. Such a clip improves workability and significantly reduces the number of man-hours compared to a method that uses screws or the like as a fixing means. Further, short hair flocks 10 may be provided at the tip of the lip portion 6c.

FIG. 3 shows a second embodiment of a double seal. The weather strip 6 of the second embodiment is similar to the weather strip 6 of the second embodiment.
A second lip portion 6e is further provided in the example. That is, the bent vertical surface 7a of the window shoulder 7
It has an extension part 6d extending from the lower end of the base part 6a in contact with the outside, that is, in the direction of the panel surface of the outer panel 4, and a lip part 6e extending diagonally upward from the end of this extension part 6d and coming into contact with the window glass 2.
In this case as well, the hinge point of the lip portion 6e is the extension portion 6
This is the end of d. Since the two flexible lip portions 6c and 6e perform double sealing in this way, the sealing function can be reliably performed.

Although the above embodiments have been described with respect to weather strips on automobile doors, the same applies to weather strips on rear side window panels.

As is clear from the above, according to the present invention, since the hinge point is set outside the door pocket and the lip part is made longer, the window glass can be raised and lowered easily, and the flexible bending allows for a good fit and seal on the glass surface. Sexuality further improves. In particular, by displacing the window glass in the width direction, good sealing performance can be achieved in a flat surface window with a narrow door pocket.
