Weather strip
First Claim
1. A weather strip, comprising:
- a trim portion that has a substantially U-shaped form of a sectional plane thereof, that is mounted on a flange portion provided along a door opening circumference portion of a vehicle, and that is equipped with a vehicle outer-sided side wall portion, a vehicle inner-sided side wall portion, and a coupling portion for coupling both the side wall portions to each other; and
a seal portion comprising a hollow portion, in which the seal portion contacts a circumferential portion of a door of the vehicle under pressure when the door is closed,wherein the seal portion comprises;
a first elongated portion which is elongated to a vehicle outer side from a portion located in a vicinity of a boundary portion between the seal portion and the coupling portion of the vehicle outer-sided side wall portion;
a second elongated portion which is elongated to the vehicle outer side from a portion located in a vicinity of a tip portion of the vehicle outer-sided side wall portion; and
an expanded portion having substantially an arc shape, which constitutes a convex shape on the vehicle outer side, the expanded portion coupling a tip portion of the first elongated portion to a tip portion of the second elongated portion,wherein the first and second elongated portions comprise a same material, and the expanded portion comprises a sponge material,wherein the weather strip further comprises;
a bridge for coupling the expanded portion to a portion located in a vicinity of a boundary portion between the bridge and a first extended portion of the vehicle outer-sided side wall portion within the hollow portion, and for dividing the hollow portion into a first hollow portion on an inner circumferential side of the door opening, and a second hollow portion on an outer circumferential side of the door opening; and
a portion within the expanded portion, which forms the first hollow portion, said portion within the expanded portion abuts against the circumferential portion of the door and is depressed to a vehicle inner side when the door is closed,wherein the expanded portion comprises;
a thicker-thickness portion comprising a portion which abuts against the circumferential portion of the door when the door is closed, the thicker-thickness portion being located at the first hollow portion; and
a thinner-thickness portion located between the thicker-thickness portion and a contact portion of the bridge, and between the thicker-thickness portion and a tip portion of the first elongated portion,wherein the bridge comprises the sponge material,wherein a lip portion is located between the expanded portion to and an inner circumferential side of a door opening, andwherein a thickness of an entirety of the portion of the thicker-thickness portion which abuts against the circumferential portion of the door is greater that a thickness of an entirety of a remaining portion of the first hollow portion other than the portion of the thicker-thickness portion which abuts against the circumferential portion of the door.

Abstract
A weather strip includes a trim portion that is a substantially U-shaped, that is mounted on a flange portion provided along a door opening circumference portion of a vehicle, and that is equipped with a vehicle outer-sided side wall portion, a vehicle inner-sided side wall portion, and a coupling portion for coupling the side wall portions to each other, and a seal portion including a hollow portion. The seal portion includes a first elongated portion which is elongated to a vehicle outer side from a portion located in a vicinity of a boundary portion between the seal portion and the coupling portion of the vehicle outer-sided side wall portion, a second elongated portion which is elongated to a vehicle outer side from a portion located in a vicinity of a tip portion of the vehicle outer-sided side wall portion, and an expanded portion having substantially an arc shape.
