Abstract

A grommet for a vehicle includes a body mounted in a wiring hole of a vehicle panel through a mounting part provided on an outer circumference thereof, a first outer tube and a second outer tube formed to extend from opposite sides of the body in the direction of opposite surfaces of the panel, a partition wall extending between the first and second outer tubes from an inner circumference of the body, and an inner tube extending to the outside of the first outer tube by penetrate the inside of the first outer tube from the partition wall in order to support a wire passing through the wiring hole, wherein the inner tube includes a first section provided to be rolled and entered in the direction of the second outer tube, and the first section includes a first entry section capable of entering the inside of the second outer tube.

First claim

The invention claimed is:

1 . A grommet for a vehicle comprising:
a body mounted in a wiring hole of a vehicle panel through a mounting part provided on an outer circumference of the vehicle panel; a first outer tube extending from one side of the body from a first surface of the vehicle panel in a first direction; a second outer tube extending from an opposite side of the body from a second, opposite surface of the vehicle panel in a second direction; a partition wall extending between the first and second outer tubes from an inner circumference of the body; and an inner tube extending to the outside of the first outer tube by penetrating the inside of the first outer tube from the partition wall to support a wire passing through the wiring hole; wherein the inner tube includes a first section rolled and inserted in the direction of the second outer tube; wherein the first section includes a first entry section configured to be inserted into the inside of the second outer tube; wherein the first section is overlapped and located on the inside of the second outer tube; and wherein the first entry section includes an inverted section in which inner and outer peripheries are inverted, and a non-inverted section in which inner and outer peripheries are not inverted and are overlapping each other.

2 . The grommet according to claim 1 , wherein at least a portion of the first entry section is positioned outside the first outer tube.

3 . The grommet according to claim 1 , wherein an outer circumference of an end of the inner tube comprises a locking protrusion extending outwardly from the inner tube, and the locking protrusion is provided such that the first entry section is caught on the first outer tube when the first entry section is completely inserted into the second outer tube.

4 . A grommet for a vehicle comprising:
a body mounted in a wiring hole of a vehicle panel through a mounting part provided on an outer circumference of the vehicle panel; a first outer tube extending from one side of the body from a first surface of the vehicle panel in a first direction; a second outer tube extending from an opposite side of the body from a second, opposite surface of the vehicle panel in a second direction; a partition wall extending between the first and second outer tubes from an inner circumference of the body; and an inner tube extending to the outside of the first outer tube by penetrating the inside of the first outer tube from the partition wall to support a wire passing through the wiring hole; wherein the inner tube includes a first section rolled and inserted in the direction of the second outer tube; wherein the first section includes a first entry section configured to be inserted into the inside of the second outer tube; and wherein the inner tube includes a folding induction groove configured to induce folding of the first section so that the first section is rolled in the direction of the second outer tube.

5 . The grommet according to claim 4 , wherein the folding induction groove is provided on an outer circumference of the inner tube between the partition wall and the first section.

6 . The grommet according to claim 1 , wherein the second outer tube is divided into a plurality of parts along a circumferential direction by including cutout portions formed along an axial direction on a circumference of the second outer tube.

7 . The grommet according to claim 1 , wherein a length of the inner tube is longer than a sum of lengths of the body, the first outer tube, and the second outer tube.

8 . The grommet according to claim 1 , wherein a length of the inner tube is longer than a sum of twice lengths of the body, the first outer tube, and the second outer tube.

9 . A grommet for a vehicle comprising:
a body mounted in a wiring hole of a vehicle panel through a mounting part provided on an outer circumference of the vehicle panel; a first outer tube extending from one side of the body from a first surface of the vehicle panel in a first direction; a second outer tube extending from an opposite side of the body from a second, opposite surface of the vehicle panel in a second direction; a partition wall extending between the first and second outer tubes from an inner circumference of the body; and an inner tube extending to the outside of the first outer tube by penetrating the inside of the first outer tube from the partition wall to support a wire passing through the wiring hole; wherein the inner tube includes a first section rolled and inserted in the direction of the second outer tube; wherein the first section includes a first entry section configured to be inserted into the inside of the second outer tube; and wherein the first entry section includes an inversion section entering the second outer tube when inner and outer circumferences are inverted to face the inner circumference of the second outer tube, and a non-inversion section entering the second outer tube without inversion of the inner and outer circumferences to overlap the inside of the first entry section, and a first concave-convex portion in the form of a serration is provided on the inner circumference of at least a portion of the non-inversion section.

10 . The grommet according to claim 9 , wherein the inner tube further includes a second section connected to the first section,
the second section includes a second entry section entering the first outer tube when the first entry section enters the second outer tube, and a second concave-convex portion in the form of a serration is provided on the inner circumference of at least a portion of the second entry section.
