Abstract

A glass run for an automobile door is provided with an enhanced look of a design portion thereof, allowing the glass run to be deformed easily along the curved shape of a window frame during assembly to the window frame, thereby improving ease of assembly. The glass run includes a glass run body 21 including upper and lower planar portions 23 a and 23 c , and a design portion 29 forming part of appearance design of an automobile. A material forming the upper and lower planar portions 23 a and 23 c and a material forming the design portion 29 respectively contain a resin as a main ingredient. The material forming the design portion 29 is less rigid than the material forming the upper and lower planar portions 23 a and 23 c.

First claim

The invention claimed is:

1. A glass run for an automobile door, the glass run being assembled from outside a cabin to a window frame which extends to define a window opening of the automobile door, and sealing a gap between the window frame and a window glass, the glass run comprising:
a glass run body which is assembled to a glass run-mounting planar portion of the window frame, the glass run-mounting planar portion protruding toward the outside of the cabin,
wherein:
the glass run body includes:
a first planar portion having an outer end,
a second planar portion having an outer end, the second planar portion being separate and spaced apart from the first planar portion in a vertical direction of an automobile, the first and second planar portions each extending in a widthwise direction of the automobile to sandwich the glass run-mounting planar portion from both sides in a thickness direction thereof, and
a design portion having a surface that contacts each of and extends at least between the outer end of the first planar portion and the outer end of the second planar portion, the design portion forming a bridge between the separate first and second planar portions and forming part of appearance design of the automobile, the outer ends facing outside the cabin,

a material forming the first and second planar portions and a material forming the design portion respectively contain a resin as a main ingredient, and
the material forming the design portion is less rigid than the material forming the first and second planar portions.

2. The glass run of claim 1 , further comprising:
a seal which is made of an elastic material and comes into contact with the window glass,
wherein the material forming the design portion is more rigid than the elastic material forming the seal.

3. The glass run of claim 1 , wherein the outer ends of the first and second planar portions are joined to the design portion while being spaced from each other.

4. The glass run of claim 1 , wherein:
the glass run body includes a planar coupling portion which couples together the outer ends of the first and second planar portions,
the planar coupling portion is made of the material forming the first and second planar portions,
the design portion covers an outer surface of the planar coupling portion facing outside the cabin, and
the planar coupling portion is thinner than the design portion.

5. The glass run of claim 1 , wherein the design portion protrudes toward an inside of the window opening.

6. The glass run of claim 1 , wherein the material forming the design portion has a lower flexural modulus than the material forming the first and second planar portions.

7. The glass run of claim 1 , wherein:
the surface of the design portion has first and second opposing ends;
the first end of the design portion aligns with and contacts the outer end of the first planar portion; and
the second end of the design portion extends a distance beyond the outer end of the second planar portion, such that the outer end of the second planar portion contacts the surface of the design portion at a point intermediate the first and second opposing ends.

8. The glass run of claim 7 , wherein the distance the second end of the design portion extends beyond the outer end of the second planar portion is greater than a distance between the outer end of the second planar portion and one end of the window glass when the window glass is in a fully closed state.

9. The glass run of claim 8 , wherein at least the second end of the design portion is configured to support the window glass from outside the cabin when the window glass is in the fully closed state.

10. The glass run of claim 7 , wherein the material forming the design portion has a lower flexural modulus than the material forming the first and second planar portions.

11. The glass run of claim 1 , wherein a second end of the design portion extends beyond the outer end of the second planar portion a distance that is greater than a distance between the outer end of the second planar portion and one end of the window glass when the window glass is in a fully closed state.

12. The glass run of claim 11 , wherein at least the second end of the design portion is configured to support the window glass from outside the cabin when the window glass is in the fully closed state.

13. The glass run of claim 11 , wherein the material forming the design portion has a lower flexural modulus than the material forming the first and second planar portions.

14. The glass run of claim 1 , wherein a first end of the design portion is aligned with and directly contacts the outer end of the first planar portion.

15. A glass run for an automobile door, the glass run being assembled from outside a cabin to a window frame which extends to define a window opening of the automobile door, and sealing a gap between the window frame and a window glass, the glass run comprising:
a glass run body which is assembled to a glass run-mounting planar portion of the window frame, the glass run-mounting planar portion protruding toward the outside of the cabin,
wherein:
the glass run body includes:
a first planar portion and a second planar portion extending in a widthwise direction of an automobile to sandwich the glass run-mounting planar portion from both sides in a thickness direction thereof, and
a design portion extending at least between an outer end of the first planar portion and an outer end of the second planar portion, the design portion forming part of appearance design of the automobile, the outer ends facing outside the cabin,

a material forming the first and second planar portions and a material forming the design portion respectively contain a resin as a main ingredient,
the material forming the design portion is less rigid than the material forming the first and second planar portions, and
the design portion and the first and second planar portions are extrusion-molded into a linear shape.

16. The glass run of claim 15 , wherein:
the material forming the design portion has a flexural modulus of 300 MPa or more and 2000 MPa or less, and
the material forming the first and second planar portions has a flexural modulus of 2000 MPa or more and 5000 MPa or less.

17. The glass run of claim 15 , wherein:
the material forming the design portion has a flexural modulus between 300 MPa and 2000 MPa, and
the material forming the first and second planar portions has a flexural modulus between 2000 MPa and 5000 MPa.
