Abstract

This belt molding abuts against a window pane which is attached to a window opening of a vehicle door so as to be able to move up and down. The belt molding includes at least two or more sealing portions, and abutment portions are formed on the respective sealing portions. Fiber layers) made of numerous fibers are formed on the abutment portions, and types of the fibers forming the fiber layers are different from each other. Accordingly, abutment portions suitable for the respective sealing portions can be obtained depending on positions where the sealing portions are formed.

First claim

The invention claimed is:

1. A belt molding attached to a vehicle door and abutting against a window pane that is arranged in a window opening of a door body and can be moved up and down, the belt molding comprising:
an elongated body portion attached along a flange of the window opening; and
two elongated sealing portions (i) integrally formed with the elongated body portion, (ii) protruding from upper and lower parts of a lateral wall portion of the elongated body portion that faces the window pane, (iii) each attached to the lateral wall portion by way of a seal root portion that is thinner than the corresponding sealing portion, and (iv) each having one of two elongated abutment portions that are formed by an elastically deformable material along a longitudinal direction of the body portion and that abut against the window pane, wherein:
fibers are secured to the abutment portion of each of the sealing portions, each of the abutment portions having secured thereto only one type of the fibers,
a base material is adhered to each of the abutment portions so that an entire surface of the base material is adhered to the sealing portion that has the least one abutment portion, the fibers of each of the abutment portions being erected from a surface of the base material; and
the fibers of one of the abutment portions are thinner than the fibers of another of the abutment portions.

2. The belt molding according to claim 1 , wherein:
the fibers of one of the abutment portions are shorter than the fibers of another of the abutment portions.

3. The belt molding according to claim 2 , wherein:
the fibers of the abutment portion of the sealing portion arranged on the upper part of the lateral wall portion are longer than the fibers of the abutment portion of the sealing portion arranged on the lower part of the lateral wall portion.

4. The belt molding according to claim 1 , wherein:
the length of the fibers of at least one of the abutment portions is 0.3 mm or greater and 1.0 mm or smaller.

5. The belt molding according to claim 1 , wherein:
the fibers of the abutment portion of the sealing portion arranged on the lower part of the lateral wall portion are thinner than the fibers of the abutment portion of the sealing portion arranged on the upper part of the lateral wall portion.

6. The belt molding according to claim 1 , wherein:
the thickness of the fibers of at least one of the abutment portions is 1.0 decitex or greater and 4.5 decitex or smaller.

7. The belt molding according to claim 1 , wherein:
the fibers of at least one of the abutment portions are made of nylon-based resin.

8. The belt molding according to claim 7 , wherein:
the fibers of the abutment portion of the sealing portion arranged on the upper part of the lateral wall portion are made of polyester-based resin, and the fibers of the abutment portion of the sealing portion arranged on the lower part of the lateral wall portion are made of nylon-based resin.

9. The belt molding according to claim 1 , wherein:
the fibers of at least one of the abutment portions are made of polyester-based resin.

10. The belt molding according to claim 1 , wherein:
the belt molding is an inner belt molding attached to an interior side of the vehicle door.

11. The belt molding according to claim 1 , wherein:
the belt molding is an outer belt molding attached to an exterior side of the vehicle door.

12. The belt molding according to claim 1 , wherein:
the fibers of at least one of the abutment portions are shorter than a thickness of the corresponding sealing portion.

13. A belt molding attached to a vehicle door and abutting against a window pane that is arranged in a window opening of a door body and can be moved up and down, the belt molding comprising:
an elongated body portion attached along a flange of the window opening; and
two sealing portions (i) integrally formed with the elongated body portion, (ii) protruding from upper and lower parts of a lateral wall portion of the elongated body portion that faces the window pane, (iii) one being a lip and the other being a ridge with a substantially semicircular cross-section, and (iv) each having one of two abutment portions that are formed by an elastically deformable material along a longitudinal direction of the body portion and that abut against the window pane, wherein:
fibers are secured to the abutment portion of each of the sealing portions, each of the abutment portions having secured thereto only one type of the fibers,
a base material is adhered to each of the abutment portions so that an entire surface of the base material is adhered to the sealing portion that has the abutment portion, the fibers of each of the abutment portions being erected from a surface of the base material; and
the fibers of one of the abutment portions are thinner than the fibers of another of the abutment portions.
