Description

DETAILED DESCRIPTION OF THE INVENTION Object of the Invention (Industrial field of application) The present invention relates to a weatherstrip for an automobile, particularly a weatherstrip for sealing a rear side glass and a front side glass such as a rear door glass and a rear quarter glass. .

(Prior Art) Conventionally, as shown in FIG. 3, an extension portion extending forward inward of a rear side glass 21 such as a rear quarter glass of a sashless door vehicle or a rear door glass of a 4-door hard top vehicle is provided in a front portion. The holding portion 23 integrally formed with the metal insert 26 is attached. Further, a seal lip 27 is formed at the end of the holding portion 23, which constitutes a weather strip together with the holding portion 23. Then, when the front side glass 22 is closed, the seal lip 27 comes into contact with the front side glass 22, so that the space between the front side glass 22 and the rear side glass 21 is sealed.

(Problems to be solved by the invention) However, the assembly error that occurs when the front side glass 22, the rear side glass 21, and the weather strip are assembled, and the product error such as the shape and size of each member itself is complete. Is inevitable. Therefore, in order to absorb these errors, the front side glass 2
A gap A of 5 to 6 mm is provided between 2 and the holding portion 23. Further, when the holding portion 23 and the insert 26 are molded, the insert 26 is provided with a mold pin (not shown) for supporting the insert portion 26 from the gap A side.

Therefore, since the gap A and the hole formed by the pin of the mold are visible from the outside of the vehicle, the appearance is deteriorated. Also, the same gap A
Since rainwater and dust easily remain on the seal lip 27
And the contact force with respect to the front side glass 22 is reduced, and there is a risk that water may invade when water is applied with high pressure during car washing. There was also the problem of noise coming from outside the car.

Configuration of the Invention (Means for Solving the Problems) In order to solve the above problems, the present invention provides a predetermined gap between the front edge of the rear side glass and the rear edge of the front side glass. A front end surface of the holding portion, in which a holding portion is attached, and a weather strip having a seal lip provided so as to come into contact with a surface of the front side glass on the inner side of the vehicle from an extension portion extending forward on the inner side of the holding portion. In this method, a hollow seal portion that abuts on the rear end surface of the front side glass is fixed, and further, the vehicle-inside end portion of the seal portion is applied to the side surface of the extension portion of the holding portion within the gap.

(Operation) Since the gap between the front side glass and the holding portion and the hole formed by the pin of the molding die are closed by the hollow seal portion provided in the holding portion, the appearance from the outside of the vehicle is improved. Also,
When the front side glass is closed, the seal portion comes into contact with the end surface of the front side glass, so that water is prevented from entering and the seal lip is less likely to be deteriorated by being exposed to water.

Therefore, the contact force of the seal lip with respect to the front side glass is less reduced, and there is no possibility of intrusion even if water is applied with a high pressure during car washing. Also, noise from outside the vehicle is less likely to enter.

(Embodiment) An embodiment in which the present invention is embodied in a weather strip for a rear door glass of an automobile will be described below with reference to FIGS.

As shown in FIG. 2, a rear door glass (hereinafter, referred to as rear side glass) 1 and a front door glass (hereinafter, referred to as front side glass) 2 of a four-door hardtop vehicle 2
Each can open and close and can move up and down. The weather strip of this embodiment is attached so as to seal between the side glasses 1 and 2.

As shown in FIG. 1, a recessed line is formed at the right end of a long-shaped holding portion 3 made of EPDM (ethylene / propylene rubber) solid rubber, and the rear side glass 1 is formed here.
The tip of is attached.

That is, after the insert 6 is supported and arranged on the right end of the holding portion 3 by a die pin (not shown),
It is injection molded. The insert 6 is formed with a flat inner metal plate 4 (upper side in the drawing) and an outer metal (lower side in the drawing) that is bent and formed into a substantially Z shape and is welded and fixed to the inner metal plate 4. It is composed of a plate 5. Further, the tip portion of the rear side glass 1 is fitted to the insert 6 via an adhesive applied to the inner surface thereof.

An extension portion extending leftward is formed from an end portion of the holding portion 3 on the inner side of the vehicle, and a seal lip 7 is formed integrally with a tip end portion of the holding portion 3 so as to be outwardly curved. The seal lip 7 is gradually thinned toward its tip.

Further, a front side glass 2 is attached to the outside of the seal lip 7 so as to be openable and closable. And when the front side glass 2 is closed, the rear side glass 1
Is located on the same plane, and its inner surface contacts the seal lip 7.

By the way, between the end portion of the front side glass 2 and the holding portion 3, there is provided a hollow seal portion 8 having a substantially fan-shaped cross section formed in accordance with the shape of the space. At this time, the end portion of the seal portion 8 on the inner side of the vehicle enters and closes the gap between the seal lip 7 and the holding portion 3.

The seal portion 8 is made of foamed EPDM sponge rubber, and is firmly attached to the front end surface of the holding portion 3 and the side surface of the extension portion extending forward from the vehicle inner end portion via an adhesive. A ridge 9 is provided on the end of the holding portion 3 on the vehicle outer side so that the seal portion 8 can be easily attached and fixed. Further, the protrusion 9 prevents the adhesive surface from being seen from the outside of the vehicle.

Next, the operation and effect of the present embodiment configured as described above will be described.

First, since the seal portion 8 is provided between the end portion of the front side glass 2 and the holding portion 3, the conventional gap A generated when the front side glass 2 is closed and the gold for molding the holding portion 3 are formed. The holes of the mold are closed and the appearance from outside the vehicle is improved.

At this time, the seal lip 7 is in contact with the inside surface of the front side glass 2 and the seal portion 8 is in contact with the end surface in a pressed state. Here, since the seal portion 8 is hollow, it is possible to easily absorb an assembly error and a product error of the front side glass 2. Further, the seal portion 8 is E
Since it is a PDM sponge rubber, it has excellent weather resistance and is less likely to age and crack. Moreover, since the end portion of the inside of the vehicle of the seal portion 8 extends to the side surface of the extension portion of the holding portion 3 in the gap A, and is adhered to the side surface of the extension portion,
Even when the front side glass 2 is closed, the front side glass 2 does not enter the inside of the seal portion 8 inside the vehicle, and there is no risk that the seal portion 8 will ride on the outside surface of the front side glass 2 and spoil the appearance.

Therefore, even if it is exposed to rain or water is applied with a relatively strong pressure at the time of washing the car, it is less likely that the water will be blocked by the seal portion 8 and enter from there. As a result, the seal lip 7 is not directly exposed to water or the like, and the abutting force on the front side glass 2 is also prevented from being reduced, so that there is no risk of water entering there and noise from the outside of the vehicle does not easily enter. Become.

The present invention is not limited to the configuration of the above-described embodiment. For example, the seal portion 8 may have a circular or rectangular cross section, or a double-sided tape may be used as a fixing means of the seal portion 8 to the holding portion 3. Can also be used and further embodied in a weatherstrip attached to the rear quarter glass.

Effects of the Invention As described in detail above, according to the present invention, the gap between the rear edge of the front side glass and the holding portion is closed by the seal portion, so that the hole of the molding die pin is concealed, Not only can water and noise from entering the vehicle be blocked, but the closed front side glass also does not enter the inside of the seal part, so the seal part rides on the outside surface of the front side glass and is beautiful. The effect is that there is no fear of damaging the.
