Abstract

To provide an inexpensive routing structure, which is improved in sealing performance with no harm in noise insulation performance, of a wire harness of a sensor for a door of an automobile. The routing structure includes a wire harness of a sensor. The sensor couples to a flange of a rear door of the automobile with a bracket, and detects an electric signal which provides an indication that an object is between the rear door and a front door. The wire harness passes through a through hole, provided on an inner panel of the rear door, and is routed into a space between the inner panel and an outer panel. The through hole is a service hole, provided on a door side surface of the inner panel.

First claim

The invention claimed is:

1. A routing structure of a wire harness of a sensor for a door of an automobile, the routing structure comprising:
the sensor which couples to a flange of a rear door of the automobile, the sensor having a wire harness, and the sensor being configured to detect an electric signal which provides an indication that an object is between the rear door and a front door;
a bracket which fixes the sensor to a flange of the rear door;
the rear door which includes an inner panel and an outer panel;
a through hole which is provided on the inner panel of the rear door; and
the wire harness which passes through the through hole, and the wire harness being routed into a space between the inner panel and the outer panel, wherein
the through hole is a service hole, and the service hole is provided on a door side surface of the inner panel.

2. The routing structure as claimed in claim 1 , wherein
the wire harness is fit between a lateral side part of the bracket and the inner panel on a lower part of the rear door from the sensor before reaching to the through hole, the lateral side part of the bracket extends in a front-rear direction of the rear door from the bracket, and
the routing structure further comprises a cover member provided on the lower part of the rear door, the cover member is configured to make elastic contact with the front door when the rear door and the front door are in closed positions, and the cover member has a channel, the channel extends in the front-rear direction of the rear door, and the channel covers an inner-cabin side of the lateral side part of the bracket.

3. The routing structure as claimed in claim 2 , wherein
a front part of the channel covers a rear part of the lateral side part of the bracket, a rear part of the channel is opposite the inner panel without the lateral side part of the bracket, and
the routing structure further comprises a sponge material provided on the rear part of the channel, and the sponge material is configured to make elastic contact with the wire harness and shut a space between the inner panel and the cover member tightly.

4. The routing structure as claimed in claim 3 , wherein the routing structure further comprises a lid configured to close a rear edge of an outer-cabin side edge of the channel.
