Abstract

A door weather strip includes an installation base member and a main seal part. A die molded part on a corner part connects an extrusion molded part on a roof side and an extrusion molded part on a pillar side. An installation base member of the extrusion molded part on the roof side has a super-soft seal lip. An installation base member of the die molded part has a die molded seal lip connected to the super-soft seal lip by die molding. Thickness of the die molded seal lip is thicker in a range from a position on a straight part on a roof side of the die molded part to a position on a curve than in a range from a position of connection between the extrusion molded part on the roof side and the die molded part to the position on the straight part on the roof side.

First claim

We claim:

1 . A door weather strip comprising: an installation base member operatively coupled on a peripheral edge of a door of an automobile; and a main seal part integrally molded with an inner-cabin side of the installation base member, the main seal part making elastic contact with a door opening edge of a body when the door is in a closed position, whereby a die molded part on a corner part connects an extrusion molded part on a roof side and an extrusion molded part on a pillar side, an installation base member of said extrusion molded part on the roof side has a super-soft seal lip made of highly foamed sponge formed thereon, the super-soft seal lip making elastic contact with the peripheral edge of said door, an installation base member of said die molded part has a die molded seal lip formed thereon, the die molded seal lip making elastic contact with the peripheral edge of said door, the die molded seal lip being connected to the super-soft seal lip by die molding, wherein:
thickness of said die molded seal lip is thicker: in a range from a position on a straight part on a roof side of said die molded part to a position on a curve; or in a range from the position on said straight part on the roof side to a position on a straight part on a pillar side close to said extrusion molded part on the pillar side via said curve; than thickness of said die molded seal lip in a range from a position of connection between said extrusion molded part on the roof side and the die molded part to the position on the straight part on the roof side of said die molded part.

2 . The door weather strip as claimed in claim 1 , wherein: said super-soft seal lip lowers in height and thins in thickness towards said position of connection; and said super-soft seal lip is made to have a cross sectional shape substantially the same as said die molded seal lip and comes into contact with said die molded seal lip on said position of connection.

3 . The door weather strip as claimed in claim 1 , wherein: said super-soft seal lip lowers in height and thins in thickness towards said position of connection; and said super-soft seal lip is thicker than the thickness of said die molded seal lip and comes into contact with said die molded seal lip on said position of connection.

4 . The door weather strip as claimed in claim 2 , wherein: the height and the thickness of said super-soft seal lip is transformed by compression during the die molding; and said super-soft seal lip connects with the die molded seal lip.

5 . The door weather strip as claimed in claim 1 , wherein: said die molded seal lip is substantially perpendicular to said installation base member from the position of connection to the position on the straight part on the roof side of said die molded part;
and said die molded seal lip inclines towards an outer-cabin side with respect to said installation base member from the position on the straight part on the roof side of said die molded part to the position on said curve.

6 . The door weather strip as claimed in claim 1 , wherein: an outer-cabin side of a base root of the super-soft seal lip formed on said installation base member is closer to the peripheral edge of said door than an inner-cabin side, thereby forming the super-soft seal lip on an uneven base; and height from a top end of said super-soft seal lip to the inner-cabin side of the base root is higher than height from the top end of said super-soft seal lip to the outer-cabin side of the base root.

7 . The door weather strip as claimed in claim 3 , wherein: the height and the thickness of said super-soft seal lip is transformed by compression during the die molding; and said super-soft seal lip connects with the die molded seal lip.

8 . The door weather strip as claimed in claim 2 , wherein: said die molded seal lip is substantially perpendicular to said installation base member from the position of connection to the position on the straight part on the roof side of said die molded part; and said die molded seal lip inclines towards an outer-cabin side with respect to said installation base member from the position on the straight part on the roof side of said die molded part to the position on said curve.

9 . The door weather strip as claimed in claim 3 , wherein: said die molded seal lip is substantially perpendicular to said installation base member from the position of connection to the position on the straight part on the roof side of said die molded part; and said die molded seal lip inclines towards an outer-cabin side with respect to said installation base member from the position on the straight part on the roof side of said die molded part to the position on said curve.

10 . The door weather strip as claimed in claim 4 , wherein: said die molded seal lip is substantially perpendicular to said installation base member from the position of connection to the position on the straight part on the roof side of said die molded part; and said die molded seal lip inclines towards an outer-cabin side with respect to said installation base member from the position on the straight part on the roof side of said die molded part to the position on said curve.

11 . The door weather strip as claimed in claim 7 , wherein: said die molded seal lip is substantially perpendicular to said installation base member from the position of connection to the position on the straight part on the roof side of said die molded part; and said die molded seal lip inclines towards an outer-cabin side with respect to said installation base member from the position on the straight part on the roof side of said die molded part to the position on said curve.

12 . The door weather strip as claimed in claim 2 , wherein: a surface on an outer-cabin side of a base root as a border of the super-soft seal lip formed on a surface of said installation base member is closer to the peripheral edge of said door than a surface on an inner-cabin side, thereby forming the super-soft seal lip on an uneven base; and height from a top end of said super-soft seal lip to the surface on the inner-cabin side of the base root is higher than height from the top end of said super-soft seal lip to the surface on the outer-cabin side of the base root.

13 . The door weather strip as claimed in claim 3 , wherein: a surface on an outer-cabin side of a base root as a border of the super-soft seal lip formed on a surface of said installation base member is closer to the peripheral edge of said door than a surface on an inner-cabin side, thereby forming the super-soft seal lip on an uneven base; and height from a top end of said super-soft seal lip to the surface on the inner-cabin side of the base root is higher than height from the top end of said super-soft seal lip to the surface on the outer-cabin side of the base root.

14 . The door weather strip as claimed in claim 4 , wherein: a surface on an outer-cabin side of a base root as a border of the super-soft seal lip formed on a surface of said installation base member is closer to the peripheral edge of said door than a surface on an inner-cabin side, thereby forming the super-soft seal lip on an uneven base; and height from a top end of said super-soft seal lip to the surface on the inner-cabin side of the base root is higher than height from the top end of said super-soft seal lip to the surface on the outer-cabin side of the base root.

15 . The door weather strip as claimed in claim 7 , wherein: a surface on an outer-cabin side of a base root as a border of the super-soft seal lip formed on a surface of said installation base member is closer to the peripheral edg
