Abstract

PURPOSE:To provide a glass run which can assemble a seal portion without deformation and the lowering of retaining force even if there is unevenness in the shape size of a door frame, in the case of a glass run which is equipped with a trim portion fitted to the flange of the door frame and a hollow seal portion that is connected to the trim portion and is retained at the channel portion of the door frame. CONSTITUTION:A trim portion 51 of a U shaped section fitted to the flange 21 of a door frame 2, a hollow seal portion 52 retained at the channel portion 22 of the door frame 2 are connected to each other by means of a flexible connection portion 58 that connects in a slantingly longitudinal direction the upper end of the vehicle outside of the trim portion 51 to the lower end of the vehicle inside of the base portion 53 of the seal portion 52 which forms a U shaped section.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a glass run mounted on a vehicle door frame.

[0002]

2. Description of the Related Art In an automobile door 1 having a door frame 2 as shown in FIG. 3, a glass run is attached along the inner periphery of the door frame 2 and when the door glass 3 is closed, its upper edge is The space between the door frames 2 is sealed.

FIG. 4 shows a conventional glass run. The glass run 4 includes a trim section 41 having a U-shaped cross section attached to a flange 21 formed inside the door frame 2 and a seal section 42 connected to the trim section 41. I have it. Seal part 42
Forms a hollow body with a base portion 43 having a U-shaped cross section and a seal wall 46 connecting both ends of the opening of the base portion 43.
The seal portion 42 and the seal portion 42 are connected to each other by a connecting portion 48 that connects an upper end of the trim portion 41 on the vehicle outer side and an upper end of the base portion 43 on the vehicle inner side. The seal portion 42 is held by the channel portion 22 of the door frame 2. In some cases, the seal portion may be held by a channel-shaped molding member provided on the inner circumference of the door frame 2.

[0004]

By the way, the frame 2
The channel portion 22 may have a slight variation in cross-sectional shape. When the channel portion 22 becomes narrower than a predetermined width due to this variation, if the seal portion 42 is forcibly fitted into the door frame 2, the entire seal portion 42 is deformed, and the sealing property with the door glass 3 is improved. May decrease. On the other hand, if the width is too wide, the seal portion 42
May come off the channel portion 22.

Therefore, the present invention provides a glass run which can be stably held in the channel portion without deformation of the seal portion and fear of falling off even if the dimensions of the channel portion of the door frame vary. This was done as an issue.

[0006]

As shown in FIG. 1, the present invention is directed to a trim portion 51 having a U-shaped cross section, which is attached to a flange 21 of a door frame 2, and a seal retained in a channel portion 22 of the door frame 2. In the glass run 5A including the portion 52, a flexible connecting portion that connects the upper end on the vehicle outer side of the trim portion 51 and the open end on the vehicle inner side of the base portion 53 having a U-shaped cross-section of the seal portion 52 in a vertically inclined direction. They are connected at 58.

[0007]

The variation of the channel portion 22 of the door frame 2 is absorbed by the deformation of the connecting portion 58 which connects the trim portion 51 and the seal portion 52 in the vertically inclined direction. Therefore, the seal portion 52 is deformed by the above variation. And the seal portion 52 does not come off from the channel portion 22.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS On the inner peripheral side of the door frame 2, a flange 21 is formed by joining an inner plate and an outer plate of the door frame 2. The inner periphery of the outer plate is provided with a channel portion 22 by extending an end portion 23 on the vehicle outer side downward.

The glass run 5A includes a trim portion 51 having a U-shaped cross section, a hollow seal portion 52 connected to an upper end of the trim portion 51 on the vehicle outer side, and an inner portion extending from a lower end of the trim portion 51 on the vehicle outer side. A seal lip 57 is provided. The trim portion 51 is held by the flange 21 by a holding lip 511 protruding from the inner facing surface. The insert 6 is embedded in the trim portion 51.

The seal portion 52 forms a hollow body by a base portion 53 having a U-shaped cross section, which is open to face the upper edge of the door glass 3, and a seal wall 56 connecting the lower ends of both side walls 54 and 55 of the base portion 53. There is.

The upper end of the trim portion 51 outside the vehicle is connected to the connecting portion 5.
8, the side wall 55 on the vehicle inner side of the base portion 53 of the seal portion 52
It is connected to the lower end. The glass run 5A is an extruded body, the seal wall 56 and the inner seal lip 57 are made of sponge rubber, and the other portions are made of solid rubber.

The seal portion 52, which is attached to the door frame 2, is located diagonally above the trim portion 51 on the vehicle outer side, and has a recess formed on the outer surface of the side wall 54 on the vehicle outer side of the base portion 53. The position is held by being locked to the lower end of the outer edge 23 of the channel portion.

The connecting portion 58 has a thickness having flexibility, and in a state where the glass run 5 is attached, the connecting portion 58 extends obliquely with the trim portion 51 side facing upward.

In the glass run 5A, when the door glass 2 is lifted and closed, the inner seal lip 57 elastically hits the inner surface of the door glass 2 and the seal wall 56 of the seal portion 52 pushes up at the upper edge of the door glass 2. To be

However, in the above embodiment, the glass run 5 was used.
A is attached to the channel portion 22 of the door frame 2 in a state of being slightly pushed into the trim portion 51 side by utilizing the bending of the connecting portion 58. Therefore, even if there is a variation in the width of the channel portion 22, this variation is absorbed by the bending of the connecting portion 58, so that even if the width is narrow, the seal portion 52 can be easily attached without being deformed and the width is wide. Even so, the retainability of the seal portion 52 is ensured.

FIG. 2 shows another embodiment of the present invention. In this embodiment, the connecting portion 58 of the glass run 5B is formed in series with the sponge rubber seal wall 56. A molding member 7 whose outer end is bent downward is fixed to the door frame 2, and a seal portion 52 is held by a channel portion 72 formed by the molding member 7 and the door frame 2. The other structure is substantially the same as the previous embodiment, and the corresponding parts are designated by the same reference numerals. This embodiment also has the same effects as the previous embodiment.

[0017]

As described above, the glass run of the present invention is easy to work, is not deformed, and falls off even if the dimensions and the shape of the channel portion of the door frame vary. Instead, the seal portion can be attached to the channel portion of the door frame.
