DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door glass weatherstrip mounted along a belt line of an automobile door, and more particularly to a structure for mounting a door glass weatherstrip on an inner 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 the inner and outer weather strips.
3 shows a representative example of a mounting structure of the inner weather strip 2. The weather strip 2 includes a base 21 and a base 21.
The lip 22 is provided with upper and lower two-step lips 22 extending from the front end and contacting the inner surface of the door glass 4 (FIG. 2). The base 21 has a metal plate insert 23 embedded therein.

[0004] The insert 23 has a cut-and-raised portion 24 formed at a predetermined interval in the longitudinal direction. The cut-and-raised portion 24 is raised inside the base portion 21 and the door trim 5
The weatherstrip 2 is fixed to the interior trim 5 by inserting and bending the elongated strip 51 provided at the upper end of the interior trim 5.

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 21 of the weather strip 2 is wavy at an intermediate position between the caulking fixing portions. Floating, interior trim 5
And a gap 6 may be generated between them. The formation of the gap 6 impairs the appearance and makes the contact pressure of the lip 22 against the door glass 4 uneven.

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

[0007] However, in this means, the upper and lower U
If the width of the U-shaped groove is formed so as to be tightly fitted to the upper and lower edges of the flange portion of the interior trim, the work of inserting the interior trim becomes difficult. On the other hand, if the width is widened, insertion becomes easy, but rattling occurs after mounting. There is a problem.

[0008]

SUMMARY OF THE INVENTION The present invention relates to a weather strip mounting structure for fitting a weather strip to the upper end of an interior trim, which has good workability for fitting and does not cause looseness after fitting. The task was to do.

[0009]

Mounting structure of the weather strip of the present invention SUMMARY OF], as illustrated in Figure 1, the motor vehicle door base
The base 31 at the top of the door trim 5
Is attached, and the lip 32 extending from the base 31
Door glass weather strip abutting on the inner surface of glass 4
3, the upper edge and the lower edge of the base 31 are respectively
Formed along the upper end of the interior trim 5 as a folded shape
Upper and lower edges of the vertical wall-shaped flange portion 51 can be loosely fitted.
So that a groove 33 having a U-shaped cross section is formed over the entire length of the base,
The upper and lower edges of the flange portion 51 of the interior trim 5
The upper and lower grooves 33 are longitudinally extended from the front end side or the rear end side.
Insert them in the same direction so that they fit together.
The base 31 has a surface facing the flange 51.
The tip of the flange 51 is tightly contacted by line contact on both sides.
Of the plurality of ridges 34 in the longitudinal direction of each base 31.
And a plurality of ridges 34 after mounting.
A structure in which the flange 51 is pressed against both sides.
And

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 comes into sliding contact with the ridge 34, and the ridge 34 linearly extends in the fitting direction of the flange portion 51. Is substantially line contact, the sliding resistance is small and the fitting of the flange portion 51 is easy. After the fitting, the weather strip 3 is held by the flange portion 51 of the interior trim 5 without play by the ridges 34. .

[0011]

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

The weather strip 3 is a one-piece extruded body made of rubber or synthetic resin. The weather strip 3 has a base 31 attached to the flange 51 and an upper and lower two-stage extending from the base 31 and having a tip abutting on the inner surface of the door glass 4. A lip 32 is provided. The base 31 is made of a hard material, and the lip 32 is made of a soft material. A flocking 35 is provided on the lower surface side of each lip 32.

The center of the base 31 of the weather strip 3 in the height direction is a flat plate, 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 such that both upper and lower edges can be loosely fitted into the upper and lower grooves 33 of the base 31.

The base 3 facing the flange 51
A plurality of ridges 3 are provided on the inner surface of
4 are formed. That is, one protrusion is formed on each of the inner surfaces of the upper and lower grooves 33 on the inside of the vehicle, and one protrusion is formed on each of the bottom surface of the lower groove 33 and the inner surface of the central flat portion of the base 31. The height of these ridges 34 is such that when the flange portion 51 of the interior trim 5 is fitted to the base 31, the tip of the ridge 34 comes into close contact with the surface of the flange portion 51.

The weather strip 3 constructed as described above
Is attached to the interior trim 5 by fitting the front or rear end side of the door of the flange portion 51 of the interior trim 5 to one end of the base 31 of the weather strip 3 in the longitudinal direction, and attaching the weather strip 3 to the flange portion 51. This is done by pulling and moving along. At this time, the tip of each ridge 34 is in close contact with the flange portion 51, but the flange portion 51 and each ridge 34 are in linear line contact in the weather strip moving direction, so that the sliding resistance is small. The fitting of the flange portion 51 is easy. And, after mounting, the ridge 34 is
Are pressed against each other 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 does not rattle. Further, the ridge provided at the base of the weather strip is formed integrally when the weather strip is extruded, and does not reduce the productivity of the weather strip or increase the cost.
