Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a glass run for guiding a window glass that moves up and down in a door of an automobile.

Generally, a side door provided on the side of an automobile includes a window glass that can be raised and lowered to open and close a window opening formed by a window frame, and a glass run for sealing between the window frame and the window glass. there is Usually, a glass run includes an extruded part formed by extrusion molding and a molded part formed by mold molding, and the extruded part is placed in a mold and the molding material is injected. At the same time, the extruded part and the molded part are joined in the mold to complete the molding.

In the conventional glass run, the extruded part has an upper side extruded part that is extruded so as to substantially follow the upper side of the frame, and the upper side extruded part is attached to the flange part that protrudes toward the outside of the vehicle on the upper side of the frame. A mounting portion having a substantially U-shaped cross section is provided. As a conventional glass run, for example, Patent Document 1 discloses a glass run including an upper extruded portion provided with an attachment portion made of a hard resin material in order to ensure the retention of the glass run after it is attached to the upper side of the frame. The mounting portion vertically clamps the flange portion of the upper side of the frame so that the glass run does not drop off from the window frame. Specifically, in the glass run of Patent Document 1, the upper extruded portion includes a trim portion having a substantially U-shaped cross section made of a hard resin material as a mounting portion. a body-side sidewall and a glass-run-side sidewall that are sandwiched between the body-side sidewall and the trim portion bottom wall that connects the vehicle-exterior end of the body-side sidewall and the vehicle-exterior end of the glass-run-side sidewall (Patent Document 1 See Figure 1). By configuring in this way, the glass run can be firmly held on the door frame.

When the upper side extruded part of Patent Document 1 is adopted, the upper side extruded part is formed by extrusion molding as described above and then disposed in the mold when molding the molded part. In order to prevent misalignment, it is necessary to sandwich and fix the mounting portion of the upper extruded portion with a mold. Therefore, the hard resin material forming the mounting portion and the mold come into direct contact with each other, and the mounting portion of the upper side extruded portion may be scratched due to being fixed by the mold. Also, when the mold is removed from the upper extruded portion after molding, the mounting portion of the upper extruded portion may be scratched by the mold. Therefore, in the case of the upper extruded portion in which the hard resin material constituting the mounting portion is exposed, as described in Patent Document 1, the mounting portion is damaged due to contact with the mold, and the appearance deteriorates. be.

In order to solve this problem, for example, as described in Patent Document 2, in order to prevent direct contact between the hard resin material constituting the mounting portion and the mold during molding of the molded portion, Alternatively, it is conceivable to employ an upper extruded portion in which the entire upper surface of the mounting portion is covered with a soft material. According to such an upper side extruded portion, the soft material can function as a cushioning material between the hard resin material constituting the mounting portion and the mold during molding of the molded portion. is considered to be less likely to be scratched due to contact with the mold as described above. However, the upper extruded part usually needs to be molded by cooling and solidifying after extruding the molding material. may solidify. As a result, due to the shrinkage caused by the solidification of the soft material, force is applied in the direction in which the opening of the approximately U-shaped mounting part made of hard resin material expands, causing the opening to occur and the product shape to conform to the designed shape. Since it cannot be manufactured, it may not be possible to ensure sufficient retention of the flange.

The present invention has been made in view of the above-mentioned problems, and its object is to suppress the opening of the mounting portion during extrusion molding of the upper extruded portion and prevent scratches due to contact with the mold during molding. is to reduce

In order to achieve the above object, in the present invention, in the glass run of an automobile door, a soft portion is provided at the attachment portion of the upper side extruded portion attached to the upper side portion of the frame.

In addition, since the set area of the soft portion in the mounting portion can be minimized, it is possible to effectively suppress the opening of the mounting portion during cooling and solidification. If the thickness of the soft portion exceeds 0.3 mm, the set area of the soft portion in the attachment portion increases excessively, and the effect of suppressing the opening of the attachment portion during cooling and solidification is reduced. 0.3 mm or less is preferable.

In the glass run according to the present invention, it is preferable that the soft portion has a projection shape.

With this configuration, the soft portion functions as a cushioning material between the upper surface of the upper wall of the mounting portion and the mold during molding of the molded portion, thereby reducing scratches due to contact with the mold. In addition, it is possible to minimize the setting area of the soft portion in the mounting portion, and to effectively suppress the opening of the mounting portion during cooling and solidification.

In the glass run according to the present invention, the upper wall inclines upward toward the connecting wall with respect to the vertical direction of the center line of the window glass in a state where the mounting portion is mounted on the upper side portion of the frame. It is preferably formed as follows.

In this way, the distance between the glass run and the vehicle body becomes wider toward the connection wall side (inside the vehicle). Since it can function as a cushioning material between the mold and the mounting portion, it is possible to reduce scratches due to contact with the mold.

In the glass run according to the present invention, it is preferable that a gap is provided between the proximal end of the lip portion and the soft portion.

In this way, the setting area of the soft portion in the mounting portion can be minimized, so that opening of the mounting portion can be effectively suppressed during cooling and solidification.

According to the glass run according to the present invention, it is possible to suppress the opening of the mounting portion during extrusion molding of the upper extruded portion, and reduce scratches on the mounting portion due to contact with the mold during molding. It is possible to prevent the appearance from deteriorating.
