Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an automobile window opening edge structure.

For example, in cars with rear side windows, even if the car body is the same model, the rear side window panel may be openable or fixed depending on the specifications, but there are differences between openable and fixed rear side window panels. Naturally, therefore, the structure of the weather strip attached to the opening edge flange of the rear side window is different, and special parts are used for each.

For example, if the rear side window panel 1 is openable as shown in Fig. 2,
A welt type weather strip 2 is used. This weather strip 2 has a generally U-shaped cross section and is a mounting base that fits into an opening edge flange 4 formed in a window opening 3 on the back side of the rear side window panel 1 and approximately parallel to the surface of the rear side window panel 1. A rear side window panel 1 of the openable/closable type is integrally formed with the welt part 2a and the side wall of the welt part 2a on the outside of the vehicle.
A seal lip 2b that comes into close contact with the inner surface of the peripheral edge of the window panel 1 when the window panel 1 is closed, and a body seal lip 2c that extends from the end of the side wall and comes into close contact with the outside opening edge 5 of the molded base of the flange 4. ing. On the other hand, in order to properly bring the body seal lip 2c into close contact with the entire periphery of the molded base of the flange 4 of the vehicle exterior opening edge 5 and to perform a reliable seal, the body seal lip 2c is directed outward from the base of the opening edge flange 4. The body seal lip 2c is formed in a direction in which it widens, that is, has a tapered cross section, and forms a smooth inclined surface 6 that receives the body seal lip 2c.

On the other hand, when the rear side window panel 1 is fixed, the weather strip 9 is provided with a flange fitting groove 9a and a window panel fitting groove 9b, as shown in FIG.
The flange fitting groove 9a is fitted into the opening edge flange 4, and the peripheral edge of the rear side window panel 1 is fitted into the panel fitting groove 9b, so that the rear side window panel 1 is fixedly fitted into the window opening 3. It is. Further, a body seal lip 9c and a sub-seal lip 9d are integrally molded on the outer peripheral edge of the weather strip 9 on the outside of the vehicle. A smooth portion is formed on the entire circumference of the outside opening edge 5 at a portion corresponding to the body seal lip 9c away from the flange 4 and is inclined with respect to the surface of the rear side window panel 1 to receive the body seal lip 9c. An inclined surface 7 is formed, and the body seal lip 9c is brought into close contact with the inclined surface 7, and between the inclined surface 7 and the molded base of the flange 4, the edge surface of the rear side window panel 1 is approximately parallel to the end surface perpendicular to the panel surface. The sub-seal lip 9d is brought into close contact with the general surface 8 of the opening edge formed in the opening to form a double seal.

As described above, the structures of the weather strips 2 and 9 used are different between the opening/closing type and the fixed type of the rear side window panel 1, and as a result, the sealing position of the opening edge 5 on the outside of the vehicle differs. The opening edge 5 on the outside of the vehicle has an inclined surface 6 formed at the molded base of the flange 4 for the window panel opening/closing type, and an inclined surface 7 formed at a position away from the molded base of the flange 4 for the window panel fixed type. As a result, each outer surface panel of the body, that is, the rear fender 10, was made into a dedicated component.

For this reason, when manufacturing the same model of car, even the rear fender 10 is a dedicated part on the car body assembly line, so two types must be prepared, which not only increases the number of parts management steps but also increases the amount of assembly required. There is a problem that the attachment work becomes complicated, and furthermore, there is a problem that the cost increases because each rear fender 10 is formed separately as a dedicated part. The same thing can be said when the window panel of a back door is made to be an open/close type or a fixed type, and in this case, two types of back door bodies, which are panels on the outer surface of the body, are required for the above-mentioned open/close type and fixed type. .

In view of this conventional situation, the present invention enables the use of a panel on the outer surface of the body for a window panel opening/closing type and a fixed type, thereby reducing the number of parts management man-hours on an automobile assembly line and improving the number of assembly work man-hours. This makes it possible to achieve significant cost reductions.

In order to achieve the above object, in the present invention, the entire circumference of the outer opening edge 5 of the window opening 3 is
At least the opening edge of the weather strip 2 for a retractable window panel is formed by bending outward from the base of the opening edge flange 4 formed on the back side of the window panel 1 substantially parallel to the surface of the window panel 1. A first inclined surface 6A that receives the body seal lip 2c formed at the end of the outer side wall of the attachment base 2a to the flange 4;
The opening edge general surface 8 is bent from the outer peripheral edge of the inclined surface 6A and is formed substantially parallel to the end surface perpendicular to the window panel surface of the window panel 1, and the opening edge general surface 8 is outside the outer peripheral edge of the opening edge general surface 8. When the weather strip 9 for a fixed type window panel is installed, the second inclined surface 7A is bent in the direction of widening toward the outside of the vehicle and receives the body seal lip 9c formed on the outer peripheral edge of the weather strip 9 on the outside of the vehicle. be.

Hereinafter, embodiments of the present invention will be described in detail using a rear side window as an example, with reference to the drawings and with the same reference numerals assigned to the same parts as in the conventional structure.

That is, in the present invention, as shown in FIGS. 4 and 5, there is a gap around the entire circumference of the outer side opening edge 5 of the window opening 3 on the back side of the rear side window panel 1. The opening edge flange 4 of the weather strip 2 for a retractable rear side window panel is bent in a direction widening outward from the base of the opening edge flange 4, which is formed substantially parallel to each other. The body seal lip 2 formed at the end of the side wall on the outside of the vehicle of the welt portion 2a, which is the mounting base for the
A smooth first inclined surface 6A is formed to receive the angle c. The outer peripheral edge portion of the first inclined surface 6A forms an opening edge general surface 8 that is bent approximately parallel to the end surface of the rear side window panel 1 that is perpendicular to the panel surface. Furthermore, a weather strip 9 for a fixed rear side window panel is formed in a direction that extends outward from the outer peripheral edge portion of the opening edge general surface 8 in the same manner as the first inclined surface 6A. A smooth second inclined surface 7A that receives the body seal lip 9c formed on the periphery.
has been formed.

When the rear side window panel 1 is made to be an openable type with the above embodiment structure, when the weather strip 2 for the openable window panel is fitted to the opening edge flange 4 as shown in FIG. 4, the body seal lip 2c is 1st part of flange 4 molded base
A reliable seal can be achieved in close contact with the inclined surface 6A.

On the other hand, when the rear side window panel 1 is of a fixed type, a weather strip 9 for a fixed type rear side window panel, which has the window panel 1 fitted and held in advance, is fitted onto the opening edge flange 4 as shown in FIG. For example, the body seal lip 9c comes into close contact with the second inclined surface 7A, and
The sub seal lip 9d is connected to the first inclined surface 6A and the second inclined surface 6A.
The opening edge between the opening edge and the inclined surface 7A is brought into close contact with the general surface 8, so that a reliable seal can be achieved in this case as well. Furthermore, in this embodiment, a sub-seal lip 9e is provided protruding from the outer periphery of the weather strip 9 near the flange fitting groove 9a, and the sub-seal lip 9e is brought into close contact with the first inclined surface 6A. It is triple-sealed to further improve sealing performance.

Here, especially when the window panel is an opening/closing type, since the opening edge general surface 8 is formed approximately parallel to the end surface of the window panel 1 as described above, the gap between these two should be minimized to improve the appearance. can be improved. Further, a second inclined surface 7 is provided between this opening edge general surface 8 and the outer surface of the fender 10.
A is formed, so this second inclined surface 7A
Due to the presence of the second inclined surface 7, the outer surface of the window panel 1 and the outer surface of the fender 10 are smoothly connected to form a flat surface.
Since the water can be received at A and the flow of water can be directed toward the window panel 1 side, it is possible to suppress water from flowing into the gap between the window panel 1 end surface and the opening edge general surface 8. can. Furthermore, a first inclined surface 6A is formed between the opening edge general surface 8 and the opening edge flange 4.
Since the body seal lip 2c is in close contact with the inclined surface 6A of the
The inclination of the first inclined surface 6A makes it possible to prevent the body seal lip 2c from being turned up by the force of water, thereby improving sealing performance.

In the above embodiment, the opening edge of a rear side window was explained as an example, but the present invention can also be applied to the window opening edge of a back door to obtain the same effect as described above.

As described above, according to the present invention, regardless of whether a window panel opening/closing type weather strip or a fixed type weather strip is used, each body seal lip 2
c, 9c as the first inclined surface 6A and the second inclined surface 7A.
Panel 1 on the outer surface of the body can be properly brought into close contact with the panel 1 to ensure a reliable seal.
0 can be shared between the window panel opening/closing type and the fixed type. As a result, it is possible to significantly reduce the number of man-hours required for parts management on the automobile assembly line, eliminate the need for multiple types of body panels and hinder assembly work, and furthermore, it is possible to share body panels. As a result, molding equipment and costs can be saved, resulting in significant cost reductions. In addition, especially when the window panel is an opening/closing type, the presence of the second inclined surface 7A allows the outer surface of the body panel 10 to be smoothly connected to the outer surface of the window panel 1 without any step. If you can achieve Ace and the car is directly hit by water during a car wash, this second
The inclined surface 7A allows the flow of water to be directed toward the window panel 1 side, thereby minimizing the flow of water between the end surface of the window panel 1 and the opening edge general surface 8. As a result, sealing performance can be further improved.
