ABSTRACT:

FIELD OF THE INVENTION
The present invention relates to a structure for positioning weather strips which is able to seal clearances between a door of a vehicle and a body of the vehicle when the door is closed.
BACKGROUND OF THE INVENTION
As shown in FIG.
5
and
FIG. 6
, a structure for positioning weather strips according to a conventional example is such that a roughly L-shaped weather strip
1
, for in which a sealing portion
1
a
resiliently contacting a door (not illustrated) is integrally formed, is inserted into and attached to a sash
2
which is located at the peripheral edge of an opening of the vehicle body, wherein a plate-like garnish
3
is fixed at the rear surface of the sash
2
corresponding to the vertical portion of the weather strip
1
, and further one end side of a subseal
4
is attached to the surface of the sash
2
corresponding to the upper face of the weather strip
1
in such a state where the same is in contact with the appearance lip
1
c
of the weather strip
1
.
FIG. 6
is an enlarged cross-sectional view taken along the line
6
—
6
of FIG.
5
.
Although the fixing position of the garnish
3
with respect to the sash
2
fixed by a fixing screw
6
is determined at a comparatively lower side of the vehicle body as shown in
FIG. 5
, since an insert metal member
5
, is internally incorporated in the garnish
3
, there is no problem in terms of damage to the product quality resulting from the upper end of the garnish
3
projecting in the outward direction (X direction in FIG.
6
). Therefore, as shown in
FIG. 6
, it is possible to drill holes for a clip
7
for positioning and retaining at the center of the weather strip
1
, and the weather strip
1
is fixed at the subseal
4
and sash
2
by one or more such clips.
However, it is desirable not to use an insert metal member
5
internally incorporated in a garnish
3
in order to decrease the production cost. If no insert metal member
5
is used, the upper end of the garnish
3
is liable to protrude or to be lifted since no reinforcement of the garnish
3
is provided. In order to prevent the upper end garnish
3
from protruding or being lifted, as shown in
FIG. 7
, a necessity of moving the fixing position of the garnish
3
and sash
2
by a fixing screw
8
to the upper extreme position arises.
Resultantly, a clip
9
which is used for fixing the weather strip
1
at the subseal
4
and sash
2
has been conventionally provided at a lower part position than the position of the fixing screw
8
. However, if the clip
9
is positioned at a lower portion, there arises another problem in that the upper end of the appearance clip
1
c
of the weather strip
1
protrudes inwardly of the vehicle (Y direction in FIG.
7
), thereby causing the appearance to be spoiled. Still furthermore, since the weather strip
1
and subseal
4
are unavoidably lengthened by an amount equivalent to the distance of descending the clip
9
, the metal dies of the weather strip
1
and subseal
4
have been conventionally made large-sized, thereby causing the production cost to be increased and the moldability thereof to be adversely affected.
SUMMARY OF THE INVENTION
It is an object of the invention to provide a structure for positioning weather strips, by which the protrusion or lifting of the weather strip can be prevented, according to which metal dies can be made small-sized, and which is able to effectively prevent slippage of the weather strip.
It is another object of the invention to provide a structure for positioning weather strips, the rigidity of which is further increased and the adhesivity of which is increased when a weather strip is attached, in addition to the above-mentioned object.
In order to solve the shortcomings and problems described above, a structure for positioning weather strips according to the invention is characterized in that a roughly L-shaped weather strip (
11
), for in which a seal portion (
11
a
) resiliently contacting a door is intergrally formed, is inserted into and attached to a sash (
12
) at the periphery of an opening of the vehicle body, a single garnish (
13
) in which no insert metal member (
5
) is internally incorporated fixed at the sash (
12
) corresponding to the side of the weather strip (
11
), a subseal (
14
) is attached to the sash (
12
) corresponding to the upper face of the weather strip (
11
) in such a state where the same is in contact with the weather strip (
11
), and simultaneously the weather strip (
11
) is fixed by a clip (
20
) at the subseal (
14
) at a more upper position than the fixing position of the garnish (
13
).
Furthermore, in a structure for positioning weather strips according to the invention, the subseal (
14
) is a die-molded member made of solid rubber, has an attaching surface (
14
a
) for a fixing clip formed, and the thickness of the attaching surface (
14
a
) around clip hole (
21
) provided therein is made larger than an appointed thickness (t).
The numerals in the brackets are shown in the drawings, and show the corresponding elements and parts in the preferred embodiment of the invention described hereinbelow.
With the invention, the fixing position between the weather strip and subseal is not determined at a lower position than the fixing position of the garnish but may be determined at an upper position. Therefore, with a single garnish in which no insert metal member is internally incorporated, it is possible to prevent the upper end of the weather strip from protruding and flapping and to prevent the appearance from being worsened. Furthermore, since the fixing position is determined at an upper position, the structure of the invention is very effective to prevent the weather strip from slipping.
Furthermore, in the conventional examples, since the fixing position between the weather strip and subseal was a lower position than the fixing position of the garnish, a long length of weather strip and subseal was conventionally necessary for this portion. According to the structure of the invention, this is not required anymore. That is, since the length can be shortened, the metal dies can be made small-sized equivalent to the shortening of the length, and the total production cost can be decreased in line with the downsizing of the metal dies. The molding thereof can thereby be facilitated by the downsizing of metal dies.
With the invention, in addition to the above effect and advantages, since the attaching face of a fixing clip of the weather strip is formed, the adhesivity of the clip and subseal can be increased, and the adhesivity of the subseal and a weather strip to be attached to the subseal is further increased. Furthermore, it is possible to prevent the weather strip from slipping. Since the thickness around the clip hole can be kept thicker than an appointed thickness, the rigidity of the subseal can also be increased.
