Abstract

A branch wire branching from a trunk wire of a floor harness routed to an automobile is used as a wire harness supplying power to the sliding seat. The wire harness is inserted within an extra length accommodation case, and in addition, the extra length accommodation case is fixated, facing downward, to a seat rail to which the sliding seat is slidably mounted, and is accommodated in a space below the seat rail. The wire harness U-turned within the extra length accommodation case is passed through the slider and extracted to a sliding seat side and connected to the seat harness within the sliding seat. A bottom portion of the slider is slidably mounted to a straight line direction slider sliding groove provided on a top end of the extra length accommodation case and a top portion of the slider is fixated to the sliding seat.

First claim

The invention claimed is:

1. A wire harness routing device for a sliding seat wherein a branch wire branching from a trunk wire of a floor harness routed in an automobile is used as a wire harness supplying power to the sliding seat, the wire harness is inserted into an extra length accommodation case, the extra length accommodation case being fixated facing downward to a seat rail to which the sliding seat is slidably mounted and being accommodated in a space between front and back cross members of the automobile immediately below the seat rail and the extra length accommodation case is not arranged below a seat of the sliding seat,
the extra length accommodation case is formed in a laterally oriented “J” shape and is provided with a straight line displacement portion on a top portion, and the extra length accommodation case is curved at a front end below the straight line displacement portion and has a shape that includes a bypass extending to a center point in a backfold shape, and the wire harness is inserted from the floor side to an opening provided at a lower rear end of the bypass, and the wire harness is U-turned within the extra length accommodation case and passes through a slider and is drawn out toward the sliding seat side and is connected to a seat harness within the sliding seat,
a lower portion of the slider is slidably mounted to a straight line direction slider sliding groove provided on a top end of the extra length accommodation case, and in addition, a top portion of the slider is fixated to the sliding seat, and
a wire harness passing through the extra length accommodation case and the slider is sheathed by a sheathing member of a caterpillar-type.

2. A wire harness routing structure for a sliding seat wherein a seat harness routed within the sliding seat mounted to an automobile is extended to an exterior and used as a wire harness supplying power to the sliding seat connecting to a floor harness,
an extra length accommodation case to which the wire harness is inserted and U-turned is fixated to a seat of the sliding seat, the extra length accommodation case is formed in a laterally oriented “J” shape and is provided with a straight line displacement portion on a bottom portion, and the extra length accommodation case is curved at a rear end above the straight line displacement portion and has a shape that includes a bypass extending to a center point in a backfold shape, and the wire harness continuous to the seat harness is inserted through the opening provided at an upper front end of the bypass, and a slider to which the U-turned wire harness is inserted is slidably mounted to a slider sliding groove provided at a bottom end surface of the extra length accommodation case, and a connector connected to an end portion of the wire harness is fixated to a connector holder portion provided at a lower end of the slider,
a lower portion of the slider is fixated to a seat rail on which the sliding seat is slidably mounted and the connector of the end portion of the wire harness within the connector holder portion of the lower end of the fixated slider is connected to a connector of the floor harness, and
the wire harness passing through the extra length accommodation case is sheathed by a sheathing member of a caterpillar-type.
