Abstract

A door weather strip includes an attaching base, wherein: the attaching base has a bottom side part having a plate-like shape and facing the outer circumference of the door; core removal slits are formed at a main wall of a seal lip part of a die molding part; two core removal slits are provided at the bottom side part of the attaching base, and is provided such that the core removal slits of the attaching base are located at opposite sides of the core removal slits of the hollow seal part; and one of the core removal slits of the hollow seal part is open in a direction parallel to the bottom side part of the attaching base, and the other of the core removal slits of the attaching base is open in a direction perpendicular to the bottom side part of the attaching base.

First claim

What is claimed is:

1. A door weather strip for a vehicle which is configured to be attached to an outer circumference of a door of the vehicle and to seal a space between a vehicle body opening and the door of the vehicle, the door weather strip comprising:
an extrusion molding part; and
a die molding part that connects ends of the extrusion molding part to each other, wherein:
each of the extrusion molding part and the die molding part has an attaching base, which is configured to be attached to the outer circumference of the door, a hollow seal part that is integrally formed at the attaching base and is configured to contact and form a seal with a periphery of the vehicle body opening, and a seal lip part that is integrally formed at the hollow seal part or the attaching base and is configured to contact the periphery of the vehicle body opening;
the attaching base has a bottom side part having a plate-like shape and is configured to face the outer circumference of the door;
core removal slits of the hollow seal part, which reach a hollow part of the hollow seal part, are formed at a main wall of the seal lip part of the die molding part;
two core removal slits of the attaching base, which reach the hollow part of the hollow seal part, are provided at the bottom side part of the attaching base of the die molding part and are provided such that the core removal slits of the attaching base are located at opposite sides of the core removal slits of the hollow seal part; and
one of the core removal slits of the hollow seal part is open in a direction parallel to the bottom side part of the attaching base, and the other of the core removal slits of the attaching base is open in a direction perpendicular to the bottom side part of the attaching base.

2. The door weather strip according to claim 1 , further comprising a plurality of biasing ribs of the hollow seal part, running from a vicinity of a tip of the main wall of the seal lip part of the core removal slits of the hollow seal part in a direction of the bottom side part of the attaching base.

3. The door weather strip according to claim 2 , wherein an interval between the biasing ribs of the hollow seal part ranges from 2 mm to 7 mm.

4. The door weather strip according to claim 2 , wherein the biasing ribs of the hollow seal part are formed to be in contact with an upper surface of the bottom side part of the attaching base, and are in contact with an upper surface of a vehicle inside relative to a lateral end of a vehicle outside of the upper surface of the bottom side part of the attaching base.

5. The door weather strip according to claim 1 , further comprising a water cutoff wall of hollow seal part, located between the core removal slits of the hollow seal part and hollow part of the hollow seal part which is opened and between the core removal slits of the attaching base and the hollow part of the hollow seal part which is opened.

6. The door weather strip according to claim 1 , further comprising seal projections of the attaching base, continued in a longitudinal direction and located at opposite ends of an outer surface of the bottom side part of the attaching base.

7. The door weather strip according to claim 1 , wherein each of the two core removal slits of the attaching base is elongated and extends in a longitudinal direction of the hollow seal part of the die molding part.

8. The door weather strip according to claim 7 , wherein the two core removal slits of the attaching base are configured to permit molding cores, which are used to form the hollow seal part of the die molding part, to be extracted from within the hollow seal part of the die molding part.

9. A door weather strip for a vehicle which is configured to be attached to an outer circumference of a door of the vehicle to seal a space between a vehicle body opening and the door of the vehicle, the door weather strip comprising:
an extrusion molding part; and
a die molding part that connects ends of the extrusion molding part to each other, wherein:
each of the extrusion molding part and the die molding part has an attaching base, which is configured to contact and be attached to the outer circumference of the door, a hollow seal part that is integrally formed at the attaching base and is configured to contact and form a seal with a periphery of the vehicle body opening, and a seal lip part that is integrally formed at the hollow seal part or the attaching base and is configured to contact the periphery of the vehicle body opening;
the attaching base has a bottom side part having a plate-like shape that is configured to face the outer circumference of the door;
core removal slits formed in the hollow seal part, which reach a hollow part of the hollow seal part, are formed at a main wall of the seal lip part of the die molding part;
two core removal slits of the attaching base, which reach the hollow part of the hollow seal part, are provided at the bottom side part of the attaching base of the die molding part,
the two core removal slits of the attaching base are configured to permit molding cores, which are used to form the hollow seal part of the die molding part, to be extracted from within the hollow seal part of the die molding part;
the core removal slits of the hollow seal part are located between the core removal slits of the attaching base in the longitudinal direction of the attaching base, and
an outer opening of one of the core removal slits of the hollow seal part faces a direction parallel to the bottom side part of the attaching base, and outer openings of the core removal slits of the attaching base face a direction perpendicular to the bottom side part of the attaching base.

10. The door weather strip according to claim 9 , further comprising a plurality of biasing ribs of the hollow seal part, wherein the biasing ribs extend from a vicinity of a tip of the main wall of the seal lip part of the core removal slits of the hollow seal part and toward the bottom side part of the attaching base.

11. The door weather strip according to claim 10 , wherein an interval between the biasing ribs of the hollow seal part ranges from 2 mm to 7 mm.

12. The door weather strip according to claim 10 , wherein the biasing ribs of the hollow seal part are formed to be in contact with an inner surface of the bottom side part of the attaching base.

13. The door weather strip according to claim 9 , further comprising a water cutoff wall of the hollow seal part, which is located between the core removal slits of the hollow seal part and hollow part of the hollow seal part that is opened and between the core removal slits of the attaching base and the hollow part of the hollow seal part that is opened.

14. The door weather strip according to claim 9 , further comprising seal projections of the attaching base, which continue in a longitudinal direction and are located at opposite sides of an outer surface of the bottom side part of the attaching base.

15. The door weather strip according to claim 9 , wherein each of the two core removal slits of the attaching base is elongated and extends in a longitudinal direction of the hollow seal part of the die molding part.
