Abstract

Provided is a grommet assembly including an elastic grommet main body and hard inner members to be fitted into the collar part of the grommet main body where openings for inserting electric wires are notched in part of the peripheral wall of the inner member. A lid wall is closed on an opening by way of a locking unit. A cover for protecting electric wires is integrally arranged on the inner member. The outer peripheral surface of the collar part is clamped between a door panel and a door trim. The cover is locked to the door trim by way of the locking unit. An elastic pressing member is arranged on the door trim in order to engage the pressing member with the inside of the collar part of the grommet main body thus clamping the collar part between itself and the door trim.

Claims

1. A grommet assembly comprising:

an elastic grommet main body; and

a hard inner member fitted into a collar part of the grommet main body,

wherein the inner member includes a peripheral wall which surrounds the majority of an outer circumference of an electric wire; and

wherein an opening through which the electric wire is inserted is notched in a portion of the peripheral wall of the inner member,

wherein said opening is closed by a lid wall through a locking mechanism.

2. The grommet assembly according to claim 1, wherein said inner member is integrated with a cover for protecting electric wires.

3. The grommet assembly according to claim 2, wherein said cover has an electric wire fixing part.

4. The grommet assembly according to claim 1, wherein the peripheral wall is substantially U-shaped and the opening is at the top of the U-shape.

5. The grommet assembly according to claim 4, wherein the opening is closed by a lid with two ends;

wherein a first end of the lid is integrally attached with the peripheral wall at a first side of the opening and the second end of the lid is attachable to the peripheral wall at a second side of the opening.

6. The grommet assembly according to claim 5, wherein an outer wall of the collar part corresponds to the U-shape of the peripheral wall.

7. An assembly structure of a grommet assembly to an automobile door, comprising:

a grommet assembly including an elastic grommet main body, and a hard inner member fitted into a collar part of the grommet main body,

wherein the inner member includes a peripheral wall which surrounds the majority of an outer circumference of an electric wire; and

wherein an opening through which the electric wire is inserted is notched in a portion of the peripheral wall of the inner member,

wherein the automobile door includes a door trim,

wherein said inner member is integrated with a cover for protecting electric wires, and said cover is locked to said door trim by a locking mechanism.

8. The assembly structure of a grommet assembly to an automobile door according to claim 7, further comprising the automobile door including a door panel, wherein an outer peripheral surface of said collar part is secured while being clamped by said door panel and said door trim.

9. The assembly structure of a grommet assembly to an automobile door according to claim 7, wherein the peripheral wall is substantially U-shaped and the opening is at the top of the U-shape.

10. The assembly structure of a grommet assembly to an automobile door according to claim 9, wherein the opening is closed by a lid with two ends;

wherein a first end of the lid is integrally attached with the peripheral wall at a first side of the opening and the second end of the lid is attachable to the peripheral wall at a second side of the opening.

11. The assembly structure of a grommet assembly to an automobile door according to claim 10, wherein an outer wall of the collar part corresponds to the U-shape of the peripheral wall.

12. An assembly structure of a grommet assembly to an automobile door, comprising:

a grommet assembly including an elastic grommet main body, and a hard inner member fitted into a collar part of the grommet main body,

wherein an opening through which an electric wire is inserted is notched in a portion of a peripheral wall of the inner member;

further comprising the automobile door including a door panel and a door trim, wherein an outer peripheral surface of said collar part is secured while being clamped by said door panel and said door trim; and

wherein a lip part provided on the outer peripheral surface of said collar part is in close contact with said door panel and said door trim.

13. An assembly structure of a grommet assembly to an automobile door, comprising:

a grommet assembly including an elastic grommet main body, and a hard inner member fitted into a collar part of the grommet main body,

wherein an opening through which an electric wire is inserted is notched in a portion of a peripheral wall of the inner member;

further comprising the automobile door including a door trim,

wherein an elastic pressing member is provided on said door trim, and

said pressing member is engaged with an inner surface of the collar part of said grommet main body so as to clamp the collar part with the door trim.

14. The assembly structure of a grommet assembly to an automobile door according to claim 13, wherein said pressing member includes a narrow part engaged with said opening of said inner member and a wide part in pressure contact with the projection walls on both sides of the opening.

15. The assembly structure of a grommet assembly to an automobile door according to claim 13, wherein said inner member and said pressing member are locked by a locking mechanism.
