ABSTRACT:
FIELD OF THE INVENTION
The invention relates to a weather strip for use on a sunroof of a car so as to ensure sealing property between a roof panel and a roof glass.
BACKGROUND OF THE INVENTION
A conventional weather strip for use on a sunroof is described now with reference to
FIGS. 1 and 2
.
A weather strip
20
is provided on a sunroof of a car for ensuring sealing property between a roof panel
14
and a roof glass
15
and is built in a seal holder
9
fixed to an outer peripheral end of the roof glass
15
. The weather strip
20
comprises a thicker base part
21
, a thinner barrel part
22
and a hollow seal part
23
. The seal holder
9
has a recess
10
in which the weather strip
20
is built in (hereinafter referred to as built-in recess
10
) at the outer peripheral end, and has an upper protrusion part
11
and a lower protrusion part
12
on its opening edge.
With the weather strip
20
having such a configuration, the thicker base part
21
is engaged in the built-in recess
10
of the seal holder
9
while the thinner barrel part
22
is clamped by the upper protrusion part
11
and the lower protrusion part
12
, whereby the weather strip
20
is built in the seal holder
9
, thereby allowing the hollow seal part
23
to elastically contact the roof panel
14
.
A continuous angle &thgr; between the hollow seal part
23
and the thinner barrel part
22
of the weather strip
20
is set to be 90° or more. Accordingly, a sectional shape of the thinner barrel part
22
is flat and substantially uniform in an entire thickness, or it is tapered as the upper and lower surfaces thereof are beveled in the direction from the hollow seal part
23
to the thicker base part
21
.
With the conventional weather strip
20
having such a configuration, if there do not occur variations in molding dimensions of the weather strip
20
and the seal holder
9
, the weather strip
20
can be built in the seal holder
9
at a set position. Accordingly, a high sealing property can be ensured without any problems.
However, if there occur variations in molding dimensions of the weather strip
20
and the seal holder
9
, built-in posture of the weather strip
20
relative to the seal holder
9
becomes unstable, causing a problem that sealing property becomes worsened. This problem occurs to a liner part
30
. But if it occurs to a cornered part
40
, it causes a more serious problem because it is harder to fit the weather strip
20
along the curved portions of the seal holder
9
.
SUMMARY OF THE INVENTION
The invention has been developed to solve the foregoing problems and it is an object of the invention to provide a weather strip for use on a sunroof capable of firmly building the weather strip
1
in the seal holder
9
with a stabilized posture even if there occur variations in molding dimensions of the weather strip
20
and the seal holder
9
, thereby ensuring high sealing property.
A weather strip for use on a sunroof of a car according to a first aspect of the invention ensures sealing property between a roof glass
15
and a roof panel
14
. The roof glass
15
is mounted on the sunroof of the car and has a seal holder
9
fixed to an outer peripheral end thereof and a built-in recess
10
provided on an outer peripheral end of the seal holder
9
. The weather strip
1
comprises a thicker base part
2
to be engaged in the built-in recess
10
, a hollow seal part
3
elastically contacting an opening end of the roof panel
14
. A thinner barrel part
5
is integrally formed between the thicker base part
2
and the hollow seal part
3
. The thinner barrel part
5
is clamped by an upper protrusion part
11
formed on an upper part of an opening edge of the built-in recess
10
and a lower protrusion part
12
formed on a lower part of the opening edge of the built-in recess
10
. The thinner barrel part
5
is formed such that a continuous angle &thgr; between an upper surface of the thinner barrel part
5
and the hollow seal part
3
and between the lower surface of the thinner barrel part
5
and the hollow seal part
3
are both set less than 90°, forming the upper surface an ascent slope
6
which inclines in the direction from the hollow seal part
3
toward the thicker base part
2
, while forming the lower surface a decent slope
7
which declines in the same direction.
The weather strip for use on a sunroof according to a second aspect of the invention is characterized in further comprising a hook part
13
protruding aslant from the lower end of the thicker base part
2
toward the lower protrusion part
12
.
