ABSTRACT:

BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a door weather strip with seal lips attached thereto, fitted to a door sash of an automobile, comprising the seal lips which are kept in elastic contact with a body panel.
2. Description of the Related Art
Referring to
FIGS. 1
to
3
, description is given hereinafter. There has so far been available a door sash
40
of an automobile, fitted with door weather strips
20
with a hollow seal part attached thereto, each comprising the hollow seal part
21
kept in elastic contact with a body panel
30
, and a door weather strip
50
with seal lips attached thereto, formed separately from the door weather strips
20
, and comprising the seal lips
51
kept in elastic contact with the external edge face of the body panel
30
. With the door weather strip
50
, an extrusion molded part
53
on the side of a roof
31
is connected with an extrusion molded part
53
on the side of a center pillar
32
through the intermediary of a molded part
52
forming a corner section.
With the conventional door weather strip
50
with the seal lips attached thereto, there is a case where a gap
60
is provided between edges of the respective seal lips
51
of both the extrusion molded part
53
on the side of the roof
31
and the extrusion molded part
53
on the side of the center pillar
32
, as shown in FIG.
3
.
However, if the gap
60
wider than a given magnitude (normally, the gap
60
wider than about 2 mm) is provided between the edges of both the seal lips
51
, this will cause a problem that, upon closing the door of the automobile, a follow-up characteristic of the seal lips
51
against the body panel
30
becomes less cooperative and so-called waving
70
is caused to occur mainly in the bent part of the molded part (the corner section)
52
, thereby resulting in poorer sealing characteristics, and impairing external appearance in aesthetic terms.
Thus, there is a need for solving a problem with the door weather strip
50
with seal lips attached thereto, comprising the conventional seal lips
51
, that in case the gap
60
wider than a given magnitude is provided on a vertical plane between the edges of the respective seal lips
51
of both the extrusion molded part
53
on the side of the roof
31
and the extrusion molded part
53
on the side of the center pillar
32
, the waving
70
is caused to occur mainly in the bent part of the molded part (the corner section)
52
, thereby causing both the sealing characteristics and the external appearance in aesthetic terms to deteriorate.
SUMMARY OF THE INVENTION
With reference to
FIGS. 1
,
4
, and
5
, description is given hereinafter. The present invention provides a door weather strip
10
with seal lips attached thereto, fitted to a door sash
40
, and provided with a gap
60
of a given magnitude on a vertical plane between edges of respective seal lips
11
of both an extrusion molded part
13
on the side of a roof
31
and an extrusion molded part
13
on the side of a center pillar
32
. A reinforcing rib
14
is provided along the whole length of a seal lip
11
of a molded part
12
, which connects the extrusion molded parts
13
,
13
and forms a corner section, on the interior side of an automobile where no elastic contacts with a body panel
30
is being made, thereby preventing waving
70
from occurring to the molded part
12
.
