Abstract

A wire harness sheet includes a sheet base material that has a rectangular shape formed by a pair of first side portion and a second side portion in parallel with each other and by a third side portion and a fourth side portion orthogonal to the first side portion and the second side portion; an adhesive layer that is provided on one surface of the sheet base material; and a slit which is cut into the sheet base material in such a manner that the slit is formed along and in parallel with each the third side portion and the fourth side portion between each the first side portion and the second side portion, and a placement region of an electric wire bundle.

First claim

The invention claimed is:

1. A method of manufacturing a wire harness, in which a wire harness sheet is used,
the wire harness sheet including:
a sheet base material having a rectangular shape formed by a first side portion and a second side portion which are parallel with each other and by a third side portion and a fourth side portion which are orthogonal to the first side portion and the second side portion;
an adhesive layer provided on one surface of the sheet base material on which an electric wire bundle is placed in parallel with the first side portion and the second side portion; and
slits, cut into the sheet base material between at least one of the first side portion and the second side portion and a placement region of the electric wire bundle, provided proximate to at least one of the third side portion and the fourth side portion, and formed along at least one of the third side portion and the fourth side portion,
the method comprising:
a step of placing the electric wire bundle on the one surface of the sheet base material;
a step of fixing a pair of preliminary fixing sheet piece portions which are formed on outer sides of the slits of the sheet base material to the electric wire bundle with the adhesive layer by folding each of the pair of preliminary fixing sheet piece portions in half in such a manner that a portion of one of the preliminary fixing sheet piece portions overlaps an opposite portion thereof, sandwiching the electric wire bundle therebetween; and
a step of fixing a main fixing sheet portion which is provided between the pair of preliminary fixing sheet piece portions to the electric wire bundle with the adhesive layer by folding the main fixing sheet portion in half in such a manner that a portion of the main fixing sheet portion overlaps an opposite portion thereof sandwiching the electric wire bundle therebetween after the preliminary fixing sheet piece portions are fixed to the electric wire bundle,
wherein the step of fixing the preliminary fixing sheet portions further comprises overlapping and fixing a first edge at the first side portion of the preliminary fixing sheet to a second edge at the second side portion of the preliminary fixing sheet with the adhesive layer.

2. The method of claim 1 , wherein the electric wire bundle is extended in only a straight line.

3. The method according to claim 1 ,
wherein the step of fixing the main fixing sheet portion to the electric wire bundle further comprises fixing the one surface at a first side of the main fixing sheet portion to the one surface at a second side of the main fixing sheet portion.

4. The method according to claim 1 ,
wherein the step of fixing the preliminary fixing sheet portions further comprises fixing a first adhesive on the one surface to a second adhesive on the one surface.

5. A method of manufacturing a wire harness, in which a wire harness sheet is used,
the wire harness sheet including:
a sheet base material having a rectangular shape formed by a first side portion and a second side portion which are parallel with each other and by a third side portion and a fourth side portion which are orthogonal to the first side portion and a second side portion, provided with an adhesive layer formed on one surface of the sheet base material, and bonded to itself by folded back or by overlapped, so as to adhesively fix an electric wire bundle in parallel with the first side portion by sandwiching the electric wire bundle with a sandwiching portion separated from the first side portion;
slits cut into a bonding portion between a bonding end of the first side portion and the sandwiching portion, the bonding portion being formed by bonding the sheet base material to each other with the adhesive layer, laterally extending from the electric wire bundle, and having a plane shape; and circular rip-stopping portions formed at respective ends of the slits which are positioned in the sandwiching portion,
the method comprising:
a step of adhesively fixing the electric wire bundle to the sandwiching portion by bonding the sheet base material to each other after folding back the sheet base material or overlapping the sheet base materials, while the slits and the rip-stopping portions being respectively aligned with each other such that the sheet base material is divided in half around the electric wire bundle.

6. The method of claim 5 , wherein the electric wire bundle is extended in only a straight line.

7. The method of claim 5 , wherein the slits are parallel to the third side portion and the forth side portion.

8. The method according to claim 5 ,
wherein the step of adhesively fixing the electric wire bundle to the sandwiching portion further comprises fixing the one surface at a first side of the sheet base material to the one surface at a second side of the sheet base material.

9. The method according to claim 5 ,
wherein the step of adhesively fixing the electric wire bundle to the sandwiching portion further comprises fixing a first adhesive on the one surface to a second adhesive on the one surface.
