Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door glass weather strip mounted along a belt line of an automobile door, and more particularly to a structure for mounting a door glass weather strip on the inner surface side of a door glass.

[0002]

2. Description of the Related Art In an automobile door as shown in FIG. 2, door glass weather strips (hereinafter simply referred to as "weather strips") are attached to inner and outer opening edges of an opening along a belt line 1, respectively. A seal is provided between the inner and outer opening edges and the inner and outer surfaces of the door glass, and both surfaces are wiped when the door glass is moved up and down.

FIG. 3 shows an internal and external weather strip.
1 shows a typical example of a mounting structure for an inner weather strip 2. The weather strip 2 includes a base 21 and a base 21.
It is provided with two upper and lower lips 22 extending from the front end and contacting the inner surface of the door glass 4 (FIG. 2), and a base plate 21 is embedded with a metal plate insert 23.

Cut-and-raised portions 24 are formed in the insert 23 at predetermined intervals in the longitudinal direction. The cut-and-raised portion 24 is raised to the inside of the base portion 21, and the interior trim 5 of the door is cut.
The weather strip 2 is fixed to the interior trim 5 by being inserted into a long hole 51 provided at the upper end of the and then crimped.

However, according to this mounting structure, the weather strip 2 and the interior trim 5 are firmly adhered to each other at the caulking fixing portion, but the base portion 21 of the weather strip 2 is wavy at the intermediate position of each caulking fixing portion. Lifted up, interior trim 5
A gap 6 may be formed between and. The generation of the gap 6 impairs the appearance and also makes the contact pressure of the lip 22 on the door glass 4 uneven.

Further, the base portion of the weather strip is formed in a C-shaped cross section in which the upper edge and the lower edge are respectively bent in a U shape, and the upper end of the interior trim is formed into a flange portion which is fitted into the base portion. There is also a means for inserting the upper end of the interior trim into the base from the front end side or the rear end side thereof.

However, with this means, the U above and below the base is
If the groove width of the groove is narrow enough to fit tightly on the upper and lower edges of the flange of the interior trim, it will be difficult to insert the interior trim. On the other hand, if it is wide, insertion will be easier, but play will occur after mounting. There is a problem.

[0008]

DISCLOSURE OF THE INVENTION The present invention provides a weatherstrip mounting structure in which a weatherstrip is fitted to the upper end of an interior trim. The structure has good fitting workability and prevents backlash after fitting. The task was to do.

[0009]

As shown in FIG. 1, the weather strip mounting structure according to the present invention includes a base portion 31 of the weather strip 3 which extends from a top and bottom of a weather strip 3 which abuts against the inner surface of the door glass 4. It is formed in a substantially C-shaped cross section having U-shaped grooves 33 on both edges. On the other hand, a flange portion 51 is formed along the inner surface of the base portion 31 at the upper end of the interior trim 5 of the door, and the flange portion 51 is fitted into the inner surface side of the base portion 31 from the longitudinal end. A plurality of protrusions 34, which are in close contact with the surface of the flange portion 51, are formed on the surface of the base portion 31 facing the flange portion 51 in series in the longitudinal direction of the base portion 31.

When the flange portion 51 of the interior trim 5 is fitted into the base portion 31 of the weather strip 3, the flange portion 51 slides in contact with the ridge 34, and the ridge 34 has a linear shape in the fitting direction of the flange portion 51. Is substantially in line contact with each other, the sliding resistance is small, and the flange portion 51 can be easily fitted. After the fitting, the weather strip 3 is held by the ridge 34 on the flange portion 51 of the interior trim 5 without rattling. .

[0011]

FIG. 1 shows an embodiment of the present invention, in which an interior trim 5 for covering the inner surface of the inner plate of an automobile door is shown.
Is made of synthetic resin, and a vertical wall-shaped flange portion 51 is integrally formed at the upper end forming the belt line 1 (FIG. 2) of the door.

The weather strip 3 is an integrally extruded body made of rubber or synthetic resin, and has a base portion 31 attached to the flange portion 51, and two upper and lower stages extending from the base portion 31 and the front end abutting against the inner surface of the door glass 4. It has a lip 32. The base 31 is made of a hard material, and the lip 32 is made of a soft material. Bristles 35 are applied to the lower surface side of each lip 32.

The central portion of the base portion 31 of the weather strip 3 in the height direction is flat, and both upper and lower edges thereof are folded inward to form a groove 33 having a U-shaped cross section. On the other hand, the vertical width and thickness of the flange portion 51 of the interior trim 5 are set so that both upper and lower edges can be loosely fitted in the upper and lower grooves 33 of the base portion 31.

A plurality of ridges 34 are formed on the inner surface of the base 31 along the entire length of the base 31 in the longitudinal direction. That is, one line is formed on each of the inner surfaces of the upper and lower grooves 33 on the vehicle inner side, one line is formed on each of the bottom surfaces of the lower grooves 33, and one line is formed on each of the upper and lower positions of the inner surface of the central plane portion of the base 31. The height of these protrusions 34 is such that when the flange portion 51 of the interior trim 5 is fitted into the base portion 31, the tips of the protrusions 34 are in close contact with the surface of the flange portion 51.

The weather strip 3 constructed as described above.
The interior trim 5 is attached to the interior trim 5 by fitting the front end side or the rear end side of the flange portion 51 of the interior trim 5 into one end of the base portion 31 of the weather strip 3 and pulling the weather strip 3 along the flange portion 51. This is done by moving. At this time, the tip of each protrusion 34 is in close contact with the flange portion 51, but since the flange portion 51 and each protrusion 34 are in linear contact with each other in the weather strip moving direction, the sliding resistance is small. Fitting of the flange portion 51 is easy. Further, after the attachment, the protrusions 34 are pressed against each other so as to sandwich the flange portion 51 from both sides, so that the weather strip 3 does not rattle.

[0016]

As described above, according to the present invention, the weather strip can be attached to the interior trim of the door with good workability, and the attachment state of the weather strip is stable and free from rattling. Further, the ridges provided at the base of the weather strip are integrally formed when the weather strip is extruded and do not reduce the productivity of the weather strip or increase the cost.
