Abstract

An inner weather strip including: a main body part including at least an exterior lateral wall and a top wall; a seal lip provided on an outer surface of the exterior lateral wall; and a top wall lip provided on an outer surface of the top wall, wherein at least one longitudinal direction end portion of the inner weather strip is provided with an end surface wall, and wherein the end surface wall has a size equal to or larger than a size of an area surrounded by: the seal lip; the main body part; the top wall lip; and a line connecting a tip end of the seal lip and a tip end of the top wall lip, and has a joining part at which the end surface wall and at least a part of an longitudinal direction end surface of the top wall lip are integrally joined.

First claim

What is claimed is:

1. An inner weather strip extending in a longitudinal direction, the inner weather strip being configured to be mounted to an interior beltline of a vehicle door having a window plate, and the inner weather strip having a first longitudinal direction end portion and a second longitudinal direction end portion which are configured to contact with a glass run channel mounted to the vehicle door, the inner weather strip comprising:
a main body part including an exterior lateral wall and a top wall integrally connected to an upper edge of the exterior lateral wall;
a first seal lip provided on an outer surface of the exterior lateral wall, the at least one seal lip being configured to elastically contact the window plate; and
a top wall lip provided on an outer surface of the top wall, the top wall lip being configured to elastically contact a door trim of the vehicle door, wherein:
the main body part, the first seal lip, and the top wall lip extend in the longitudinal direction from the first longitudinal direction end portion of the inner weather strip to the second longitudinal direction end portion of the inner weather strip,
at least one of the first longitudinal direction end portion and the second longitudinal direction end portion is provided with an end surface wall which extends in a transverse direction intersecting with the longitudinal direction, and
the end surface wall has a size equal to or larger than a size of an area bounded by: the first seal lip, the main body part, the top wall lip, and an inclined line connecting between an upper tip end of the first seal lip and an upper tip end of the top wall lip, where a height of the upper tip end of the first seal lip is different than a height of the upper tip end of the top wall lip at the end surface wall, the end surface wall including a first joining part at which the end surface wall and at least a part of a longitudinal direction end surface of the top wall lip are integrally joined to each other.

2. The inner weather strip according to claim 1 , wherein a height of a highest upper edge of the end surface wall is equal to or lower than a height of a highest tip end of the upper tip end of the top wall lip.

3. The inner weather strip according to claim 2 , wherein the top wall lip has a low end portion joined to the end surface wall at the first joining part, a height of the upper tip end of the top wall lip at the low end portion being lower than a height of the upper tip end of the top wall lip at locations other than the low end portion, and a partial region of the end surface wall being located above the first joining part.

4. The inner weather strip according to claim 1 , wherein the end surface wall is inclined in a direction in which an upper edge of the end surface wall converges towards the glass run channel.

5. The inner weather strip according to claim 1 , wherein the end surface wall is curved in conformity to an outer surface shape of the glass run channel.

6. The inner weather strip according to claim 1 , wherein the end surface wall extends towards an interior side of the vehicle door beyond the top wall lip.

7. The inner weather strip according to claim 1 , wherein:
the end surface wall is also integrally joined to a longitudinal direction end surface of the first seal lip at a second joining part; and
the first seal lip is inclined towards an interior side of the vehicle door at the second joining part with the end surface wall.

8. A seal structure of the vehicle door in which the inner weather strip according to claim 1 is mounted to the interior beltline of the vehicle door, the glass run channel is mounted in an upper and lower direction along an up-and-down locus of both side edges of the window plate so as to guide an up-and-down operation of the window plate, and at least one of the first longitudinal direction end portion and the second longitudinal direction end portion of the inner weather strip is in contact with the glass run channel.

9. The inner weather strip according to claim 1 , further comprising a plurality of seal lips located on the outer surface of the exterior lateral wall, the plurality of seal lips including the first seal lip and at least one second seal lip, the at least one second seal lip being located below the first seal lip, the first seal lip being an uppermost lip of the plurality of seal lips.

10. The inner weather strip according to claim 1 , wherein a second end of the first seal lip converges closer to the top wall lip in the transverse direction as the first seal lip extends from the first longitudinal direction end portion to the second longitudinal direction end portion of the inner weather strip.

11. An inner weather strip extending in a longitudinal direction, the inner weather strip being configured to be mounted to an interior beltline of a vehicle door having a window plate, and the inner weather strip having a first longitudinal direction end portion and a second longitudinal direction end portion which are configured to contact with a glass run channel mounted to the vehicle door, the inner weather strip comprising:
a main body part including an exterior lateral wall and a top wall integrally connected to an upper edge of the exterior lateral wall;
a plurality of seal lips provided on an outer surface of the exterior lateral wall, the plurality of seal lips being configured to elastically contact the window plate, an upper seal lip of the plurality of seal lips being located above the remaining seal lips of the plurality of seal lips on the outer surface of the exterior lateral wall; and
a top wall lip provided on an outer surface of the top wall, the top wall lip being configured to elastically contact a door trim of the vehicle door, wherein:
the main body part, the plurality of seal lips, and the top wall lip extend in the longitudinal direction from the first longitudinal direction end portion of the inner weather strip to the second longitudinal direction end portion of the inner weather strip,
at least one of the first longitudinal direction end portion and the second longitudinal direction end portion is provided with an end surface wall which extends in a transverse direction intersecting with the longitudinal direction, and
the end surface wall has a size equal to or larger than a size of an area bounded by: the upper seal lip, the main body part, the top wall lip, and an inclined line connecting between an upper tip end of the upper seal lip and an upper tip end of the top wall lip, where a height of the upper tip end of the upper seal lip is different than a height of the upper tip end of the top wall lip at the end surface wall, the end surface wall including a joining part at which the end surface wall and at least a part of a longitudinal direction end surface of the top wall lip are integrally joined to each other.
