Abstract

A wire guide for an airbag includes a first connection portion connected to a wire harness, a second connection portion connected to a branch wire branching off from the wire harness, and an elastic portion connecting the first and second connection portions and provided to be elastically deformable, in which a cross-section of the wire guide is formed in a ‘⊃’ shape, and the wire guide limits an installation route for the branch wire that transmits power and a control signal to a lighting emblem module provided on an airbag cover that accommodates an airbag module therein.

First claim

What is claimed is:

1 . A wire guide for an airbag, the wire guide comprising:
a first connection portion connected to a wire harness; a second connection portion connected to a branch wire branching off from the wire harness; and an elastic portion connecting the first and second connection portions and provided to be elastically deformable, wherein a cross-section of the wire guide is formed in a ‘⊃’ shape, and the wire guide limits an installation route for the branch wire that transmits power and a control signal to a lighting emblem module provided on an airbag cover that accommodates an airbag module therein.

2 . The wire guide of claim 1 , wherein the second connection portion is rotated about one end portion connected to the elastic portion in response to operation of an operator, and
wherein when the operation is released, the second connection portion is rotated to return to an original position thereof by a restoring force of the elastic portion.

3 . The wire guide of claim 1 ,
wherein the first and second connection portions are each formed in a straight bar shape, and wherein the wire guide further includes first and second fixing pieces respectively provided on the first and second connection portions and surrounding and fixing the wire harness and the branch wire, respectively.

4 . The wire guide of claim 3 , wherein the first and second fixing pieces are respectively formed to be curved or bent to surround the wire harness and the branch wire, respectively.

5 . The wire guide of claim 1 , wherein taping portions, which are configured by a fabric material or a tape having an elasticity lower than a predetermined elasticity, are respectively provided on external surfaces of the first and second connection portions in a state in which the first and second connection portions are respectively fixed to the wire harness and the branch wire to prevent abnormal noise caused by vibration.

6 . The wire guide of claim 1 , wherein the first and second connection portions each have a thickness than a thickness of the elastic portion.

7 . A wire guide for an airbag, the wire guide comprising:
a first connection portion connected to a wire harness; a second connection portion connected to a branch wire branching off from the wire harness; and an elastic portion configured to connect the first connection portion and the second connection portion, having elasticity, and configured to limit a spacing distance between the first connection portion and the second connection portion, wherein the branch wire transmits power and a control signal to a lighting emblem module provided on an airbag cover that accommodates an airbag module therein.

8 . The wire guide of claim 7 , wherein the wire guide for an airbag is made of a synthetic resin material, and the first connection portion, the second connection portion, and the elastic portion are integrated.

9 . The wire guide of claim 7 , wherein the first and second connection portions each have a thickness than a thickness of the elastic portion.

10 . The wire guide of claim 7 , further including first and second fixing pieces respectively provided on the first and second connection portions and surrounding and fixing the wire harness and the branch wire, respectively.

11 . The wire guide of claim 7 , wherein taping portions, which are configured by a fabric material or a tape having an elasticity lower than a predetermined elasticity, are respectively provided on external surfaces of the first and second connection portions in a state in which the first and second connection portions are respectively fixed to the wire harness and the branch wire to prevent abnormal noise caused by vibration.

12 . A wire guide for an airbag, the wire guide comprising:
a first connection portion connected to a wire harness; a second connection portion connected to a branch wire branching off from the wire harness; and an elastic portion configured to connect the first connection portion and the second connection portion, having elasticity, and configured to allow the first connection portion and the second connection portion to be positioned adjacent to each other, wherein the branch wire transmits power and a control signal to a lighting emblem module provided on an airbag cover that accommodates an airbag module therein.

13 . The wire guide of claim 12 ,
wherein the first and second connection portions are each formed in a straight bar shape, and wherein the wire guide further includes first and second fixing pieces respectively provided on the first and second connection portions and surrounding and fixing the wire harness and the branch wire, respectively.

14 . The wire guide of claim 13 , wherein the first and second fixing pieces are respectively formed to be curved or bent to surround the wire harness and the branch wire, respectively.

15 . The wire guide of claim 12 , wherein taping portions, which are configured by a fabric material or a tape having an elasticity lower than a predetermined elasticity, are respectively provided on external surfaces of the first and second connection portions in a state in which the first and second connection portions are respectively fixed to the wire harness and the branch wire to prevent abnormal noise caused by vibration.

16 . The wire guide of claim 12 , wherein the first and second connection portions each have a thickness than a thickness of the elastic portion.

17 . A steering wheel airbag for a vehicle, the steering wheel airbag including the wire guide for the airbag of claim 1 .
