Abstract

A wiring harness which is wired between a car body and a sliding door which slides between a closing position and an opening position so as to open and close a doorway in the car body, the wiring harness includes an external member in which one end is supported rotatably about a perpendicular axis relative to the car body and in which the other end is supported rotatably about a perpendicular axis relative to the sliding door. The external member includes bending portions at a sliding door side and at a car body side respectively in a closing state that the sliding door is disposed in the closing position. The bending portions are bent in opposite directions to each other, and a curvature radius of one of the bending portions is smaller than a curvature radius of the other of the bending portions.

First claim

What is claimed:

1. A wiring harness which is wired between a car body and a sliding door which slides between a closing position and an opening position so as to open and close a doorway in the car body, the wiring harness comprising:
an external member in which one end is supported rotatably about a perpendicular axis relative to the car body and in which the other end is supported rotatably about a perpendicular axis relative to the sliding door,
wherein the external member includes bending portions at a sliding door side and at a car body side respectively in a closing state that the sliding door is disposed in the closing position,
wherein the bending portions are bent in opposite directions to each other, and a curvature radius of one of the bending portions is smaller than a curvature radius of another of the bending portions, and
wherein the curvature radius of the other of the bending portions gradually becomes larger, as the one end and the other end become closer to each other from the closing position of the sliding door.

2. The wiring harness according to claim 1 , wherein a curvature radius of a bending portion, of the bending portions, at the sliding door side is smaller than a curvature radius of a bending portion, of the bending portions, at the car body side.

3. The wiring harness according to claim 1 , wherein a curvature radius of a bending portion, of the bending portions, at the car body side is smaller than a curvature radius of a bending portion, of the bending portions, at the sliding door side.

4. The wiring harness according to claim 1 ,
wherein the wiring harness includes a biasing device which is provided on at least one of supporting portions at the car body side and at the sliding door side and which biases the supported end of the external member about the perpendicular axis, and
wherein a biasing force of the biasing device is adjusted so that the bending portions are formed in the external member.

5. The wiring harness according to claim 1 , wherein a length of the external member and supporting positions in which the external member is supported by the car body and by the sliding door respectively, are adjusted so that the bending portions are formed in the external member.

6. The wiring harness according to claim 1 , wherein the external member includes the bending portions being pre-formed.

7. The wiring harness according to claim 1 ,
wherein the wiring harness includes a rotation restricting wall which restricts a rotation range of the supported end of the external member on at least one of supporting portions at the car body side and at the sliding door side, and
wherein the rotation range of the supported end of the external member is adjusted by the rotation restricting wall so that the bending portions are formed in the external member.

8. The wiring harness according to claim 1 , wherein a size of an accommodating space of the external member is adjusted when the sliding door is closed, so that the bending portions are formed in the external member.
