  The items shown here are exemplary and illustrative of the embodiments of the present invention, and are the most effective and easy-to-understand explanations of the principles and conceptual features of the present invention. It is stated for the purpose of providing what seems to be. In this respect, it is not intended to illustrate the structural details of the present invention beyond what is necessary for a fundamental understanding of the present invention. It will be clear to those skilled in the art how it is actually implemented.

  The wire harness assembly according to the present embodiment includes a raising material described below and a wire harness described later. Note that mass-produced wire harnesses usually vary in individual length, and when assembling such a wire harness to a raised material, it is necessary to raise the wire harness in order to eliminate errors during vehicle assembly. It is assembled so that the length of the part other than the part assembled to the material becomes a predetermined length. That is, the variation in the length of the wire harness is absorbed by the raising material to which the wire harness is assembled.

  The “lifting material” is a raising material disposed on a floor panel of a vehicle, and includes a flexible member described below.

  As long as the “flexible member” has a substantially plate shape, the size, the planar shape, and the like are not particularly limited. Examples of the flexible member include a molded product of a resin foam, a molded product obtained by thermally fusing a resin foam chip with a binder, and a nonwoven fabric used as a soundproofing material. Examples of the material of the resin foam include polyurethane (PU), acrylonitrile / butadiene / styrene copolymer (ABS), polyamide (PA), polyethylene (PE), polypropylene (PP), and other polyolefins, polystyrene (PS). ), Polyvinyl chloride (PCV), acrylic resins (PMMA, etc.), polyesters such as polyethylene terephthalate (PET), resins such as polyacetal (POM), polycarbonate (PC). In the case of the molded body, the resin foam chip may be manufactured using unused resin, but the metal shredder dust is removed from the shredder dust of the vehicle. May be used. In particular, when waste materials are used, it is preferable to use high-quality dust obtained by selecting resin foams such as polyurethane foam, various fibers, and the like from vehicle shredder dust. As this high-quality dust, a resin foam chip such as polyurethane foam is contained in an amount of 50% by mass or more (the total amount of dust is 100% by mass), and the remainder (90% by mass or more of the remainder) is a vehicle seat. The dust which is a fiber piece, such as a woven fabric used as an outer skin or the like. Furthermore, chips such as unused resin and rubber can be mixed and used as needed for quality adjustment and the like.

  The flexible member is formed so as to be recessed in the thickness direction, and a groove portion for routing the wire harness is formed, and a deformation absorbing portion for absorbing the deformation is formed. ing. And the deformation | transformation by the distortion of the said flexible member produced when the wire harness from which length varied was inserted in the said groove part by the said deformation | transformation absorption part is suppressed. That is, when the length of the groove portion and the length of the portion routed in the groove portion of the wire harness are different, when the wire harness is fitted into the groove portion, the flexible member in the groove portion is deformed to accommodate the wire harness, The deformation absorbing portion absorbs the deformation, so that the substantially plate-like shape of the flexible member is maintained.

  The “groove” is not particularly limited in shape, size, or the like as long as it is formed so as to be recessed in the thickness direction of the flexible member and the wire harness is routed. Examples of the planar shape of the groove include, for example, a linear shape (see, for example, FIGS. 2 and 3), a curved shape, a shape in which a linear groove portion and a curved groove portion are combined (see, for example, FIG. 11), and the like. Can be mentioned. Moreover, as a cross-sectional shape of this groove part, for example, a keyhole shape in which an opening having a width narrower than a width of a portion in which the wire harness is accommodated (see, for example, FIG. 4), a substantially U shape, and a substantially V shape are formed. Examples include shape. From the viewpoint of holding in the groove portion of the wire harness, the cross-sectional shape of the groove portion is preferably a keyhole shape. When the cross-sectional shape of the groove portion is a keyhole shape, the ratio W2 / W1 between the width W1 of the portion in which the wire harness is accommodated and the width W2 of the opening can be, for example, 1.1 to 4, preferably 2. .25-4, more preferably 4.

  As long as the “deformation absorbing portion” absorbs the deformation of the flexible member, the shape, size, quantity, deformation absorption form, and the like are not particularly limited. The deformation absorbing portion is, for example, a groove formed along the groove and formed so as to be recessed in the thickness direction of the flexible member, or a part of the flexible member is partially formed. It can be the portion where the density is reduced. When the said deformation absorption part is a groove | channel, the length, shape, quantity, etc. of this groove | channel are not specifically limited. When the deformation absorbing portion is a groove, the planar shape of the groove is, for example, linear (see, for example, FIGS. 2 and 3), curved (see, for example, FIGS. The cross-sectional shape includes, for example, a substantially V-shape (see, for example, FIG. 3B and FIG. 4), a substantially U-shape, and the like. be able to. Examples of the planar shape of the end of the groove include a substantially arc shape (see, for example, FIGS. 3 and 19), a polygonal shape, and the like.

  The “planar shape is curved” means that the groove-shaped deformation absorbing portion formed along the groove portion is curved so that the groove portion side is open (see, for example, FIGS. 7 and 8), The planar shape is curved so that the opposite side of the groove is open. In particular, a groove-shaped deformation absorbing portion having a planar shape that is curved is referred to as a curved absorbing portion.

  The deformation absorbing portion can be formed on, for example, both surfaces of the flexible member (see, for example, FIG. 2, FIG. 3 (A), (B), etc.). In this case, in particular, in the cross section of the flexible member at the center in the length direction of the groove portion in a direction intersecting with the groove portion, at least the first deformation absorbing portion at a position close to the nth position from the groove portion The second deformation absorbing portion located next to the first deformation absorbing portion and located near the n + 1th position from the groove portion may be formed on different surfaces of the flexible member (for example, FIG. 2, see FIGS. 3A and 3B).

  In the raising material in the present embodiment, for example, a deformation assisting portion for facilitating the deformation of the flexible member in the groove portion may be provided. As this deformation assisting part, for example, (1) an intersecting groove part formed so as to intersect with the groove part (see, for example, FIGS. 12A, 12B, 13), (2) on the bottom side of the groove part A deformation assisting groove formed and recessed in the thickness direction of the flexible member (see, eg, FIG. 14) (3) Formed on the bottom side of the groove portion and penetrates in the thickness direction of the flexible member A through-hole (for example, see FIG. 15 etc.) etc. can be mentioned.

As long as the “intersecting groove” intersects the groove, the shape, size, quantity, and the like are not particularly limited. As a form of intersection of the intersecting groove part with the groove part, for example, an orthogonal form (for example, see FIG. 12A) or a form intersecting at a predetermined angle may be used. In addition, the length of the intersecting groove portion is not particularly limited. For example, it may be the same length as the width W1 of the groove portion (for example, see FIG. 12A), or may be longer or shorter than W1. Also good. Furthermore, this crossing groove part may be formed, for example, only on the opening side of the groove part (see, for example, FIG. 12B) or may extend to the bottom side of the groove part.
The “deformation assisting groove” is not particularly limited as long as it is formed on the bottom side of the groove and is recessed in the thickness direction of the flexible member. Examples of the planar shape of the deformation assisting groove include a circular shape, an oval shape (see, for example, FIG. 14A), a polygonal shape, a rectangular shape, and the like.
The “through hole” is not particularly limited as long as it is formed at the bottom of the groove and penetrates in the thickness direction of the flexible member. Examples of the planar shape of the through hole include a circular shape, an oval shape (see, for example, FIG. 15A), a polygonal shape, a rectangular shape, and the like.

  The length, material, and the like of the “wire harness” are not particularly limited as long as the “wire harness” is routed in the groove.

(1) Configuration of Wire Harness Assembly A wire harness assembly 1 according to the present embodiment includes a raising material 2 and a wire harness 3. The raising material 2 is arrange | positioned on the floor panel 10 of a vehicle, as shown in FIG. The floor panel 10 is provided with reinforcing members 10A, 10B, a tunnel 10C for passing a propeller shaft, a muffler, and the like, and members (not shown) so as to protrude upward. The raising material 2 is disposed on such a floor panel 10 so as to flatten the floor surface in the passenger compartment and to provide cushioning properties.

  As shown in FIGS. 2 and 3A and 3B, the raising material 2 includes a substantially plate-like flexible member 4. The flexible member 4 is a molded product of foamed polyurethane. The flexible member 4 is formed with a groove portion 5 and a deformation absorbing portion 6.

  As shown in FIG. 3B, the groove 5 is formed so that the planar shape is linear and is recessed in the thickness direction of the flexible member 4. The wire harness 3 is routed in the groove 5. As shown in FIG. 4, the groove portion 5 is a portion in which the wire harness 3 is accommodated, and includes a housing portion 5 </ b> A having a substantially circular cross section and an opening 5 </ b> B for inserting the wire harness 3. The width W2 of the opening 5B is narrower than the width W1 corresponding to the diameter of the accommodating portion 5A, and the ratio W2 / W1 is set to be about 0.25. The width W1 of the accommodating portion 5A is set to about 1.1 times the diameter of the wire harness 3 to be routed.

  The deformation absorbing portion 6 is a groove formed along the groove portion 5 as shown in FIG. 2 and FIGS. 3A and 3B, so as to be indented in the thickness direction of the flexible member 4. A plurality (6 in total, 3 on one side in FIG. 2) are formed on both sides in the width direction of the groove 5. The deformation absorbing portion 6 has a straight planar shape, and the planar shape of the end portion is a substantially semicircular arc shape. Further, as shown in FIG. 3B, the deformation absorbing portion 6 has a substantially V-shaped cross section. These deformation absorbing portions 6 are formed with the same length and the same cross-sectional shape.

As shown in FIGS. 2 and 3A and 3B, the deformation absorbing portion 6 is formed symmetrically on both sides of the groove portion 5 with the center in the length direction of the groove portion 5 as the axis of symmetry. It is formed on both surfaces of the flexible member 4. That is, the deformation absorbing portion 6 is a position closest to the first from the groove portion 5, and is a position closest to the deformation absorbing portion 6 </ b> A and the second position from the groove portion 5 on the surface opposite to the surface on which the groove portion 5 is formed. The deformation absorbing portion 6B on the surface on which the groove portion 5 is formed, the deformation absorbing portion 6C on the surface opposite to the surface on which the groove portion 5 is formed at the third closest position from the groove portion 5, and so on. The flexible members 4 are alternately formed on different surfaces.
As shown in FIG. 4, the ratio h / w of the groove depth h to the opening width w of the deformation absorbing portion 6 is set to about 0.87. In addition, the relationship between the depth h of the groove of the deformation absorbing portion 6 and the thickness t of the flexible member 4 is set to satisfy h ≦ t− (5 to 10 mm).

(2) Operation of Wire Harness Assembly Next, the operation of the wire harness assembly 1 having the above configuration will be described.
As shown in FIG. 5, the wire harness 3 is fitted from the opening 5 </ b> B of the groove portion 5 of the raising material 2 and accommodated in the accommodating portion 5 </ b> A, and the wire harness assembly 1 is assembled. As described above, mass-produced wire harnesses usually vary in individual length. When assembling such a wire harness to the raising material, as shown in FIG. 6 (A), in order to eliminate an error at the time of assembling the vehicle, a portion other than the portion assembled to the raising material 2 of the wire harness 3 is used. The wire harness 3 is positioned with respect to the raising material 2 and assembled so that the lengths L1 and L2 of the portions are respectively predetermined lengths.
Here, when the length L2 of the portion accommodated in the groove 5 of the wire harness 3 is longer than the length L1 of the groove 5, the flexible member 4 is distorted as shown in FIGS. 6 (A) and 6 (B). Then, in FIG. 6 (A), the extra length is absorbed by being deformed so as to bend in the left direction, and the wire harness 3 is accommodated in the groove 5. The deformation of the flexible member 4 in the groove portion 5 is absorbed by the deformation absorbing portion 6. That is, the deformation is absorbed by the deformation of the flexible member 4 in the deformation absorbing portion 6 following the deformation of the flexible member 4 in the groove portion 5, and the substantially plate-like shape of the raising material 2 is maintained.

(3) Effect of Example As described above, according to the wire harness assembly 1 of this example, the raising member 2 includes the substantially plate-like flexible member 4, and the wire harness 3 is attached to the flexible member 4. A groove portion 5 for routing and a deformation absorbing portion 6 for absorbing deformation are formed. And the deformation | transformation by the distortion of the flexible member 4 produced when the wire harness from which length varied was inserted in the groove part 5 by the deformation | transformation absorption part 6 is suppressed. Thereby, the extra length of the wire harness 3 can be accommodated in the groove part 5 without protruding from the groove part 5. Moreover, the deformation | transformation of the flexible member 4 by the dispersion | variation in the length of a wire harness can be absorbed only by inserting the wire harness 3 in the groove part 5, and the shape of the raising material 2 can be hold | maintained.

  Moreover, since the deformation | transformation absorption part 6 is a groove | channel formed so that it might be formed in the thickness direction of the flexible member 4 along the groove part 5, a deformation | transformation of the flexible member 4 can be carried out by simple structure. It can be set as the raising material 2 which can be absorbed.

  Further, the deformation absorbing portion 6 is formed on both surfaces of the flexible member 4, and in the cross section of the flexible member 4 when cut in a direction intersecting the groove portion 5 at the center in the length direction of the groove portion 5, the groove portion The deformation absorbing portion 6A at the position closest to the first from 5 and the deformation absorbing portion 6B at the position closest to the groove 5 adjacent to the deformation absorbing portion 6A are located on different surfaces of the flexible member 4, respectively. Since it is formed, both surfaces of the flexible member 4 are deformed in a balanced manner, and the substantially plate-like shape of the raising material 2 can be held more easily.

  In addition, in this invention, it can restrict to what is shown to said specific Example, It can be set as the Example variously changed within the range of this invention according to the objective and the use. That is, in the said Example, although the deformation | transformation absorption part 6A-6C formed in plurality was made into the same length, it is not limited to this, For example, the some deformation | transformation absorption part may be formed in different length, respectively. That is, for example, the plurality of deformation absorbing portions may be formed so that the lengths thereof become shorter or longer as the distance from the groove portion increases.

  Moreover, in the said Example, although the planar shape formed the linear deformation | transformation absorption part 6, it is not limited to this, For example, as shown in FIG. A curved bend absorbing portion 16 may be formed. In this case, as shown in FIGS. 7 and 8, the plurality of curved absorbing portions 16 may be formed so that each arc length is different. Furthermore, it is good also as a curve absorption part curved in the direction opposite to the curve direction with respect to the groove part 5 of the curve absorption part 16 shown to FIG.

  Furthermore, in the above embodiment, the deformation absorbing portions 6 are provided on both sides of the groove portion 5 so as to be symmetric with respect to the groove portion 5, but the present invention is not limited to this. For example, as shown in FIG. The deformation absorbing portion 6 may be formed only on one side of the groove 5, or the deformation absorbing portion 6 may be formed on both sides of the groove portion 5 while being shifted in the length direction of the groove portion 5, as shown in FIG. .

  Moreover, in the said Example, although planar shape formed the groove part 5 with a linear shape, it is not limited to this, For example, as shown in FIG. 11, the curved groove part 15A with a curved planar shape is formed. Alternatively, the deformation absorbing portion 6 may be formed so as to be aligned with the curved groove portion 15A. Thereby, even if the length of the wire harness 3 is shorter than the length of the groove 15, the wire harness 3 can be fitted into the groove 15 by deforming the curved groove 15 </ b> A into a linear shape.

  Furthermore, in the said Example, although only the groove part 5 and the deformation | transformation absorption part 6 were formed, it is not limited to this, For example, as shown to FIG. 12 (A) and (B), as a deformation | transformation auxiliary | assistant part, You may make it form the crossing groove part 7 which cross | intersects the groove part 5. FIG. By forming such a crossing groove part, as shown in FIG. 13, when the wire harness is fitted into the groove part, the flexible member can be more easily deformed. As shown in FIG. 14, a deformation assisting groove 8 that is formed on the bottom side of the groove 5 and is recessed in the thickness direction of the flexible member 4 may be formed as the deformation assisting section. Furthermore, as shown in FIG. 15, a through hole 9 that is formed on the bottom side of the groove 5 and penetrates in the thickness direction of the flexible member 4 may be formed as a deformation assisting portion.

  Moreover, in the said Example, the deformation | transformation absorption part 6 is the position nearest to the 1st from the groove part 5, Comprising: The deformation | transformation absorption part 6A and the 2nd from the groove part 5 in the surface on the opposite side to the surface in which the groove part 5 is formed. Although the deformation absorbing portion 6B is formed on the surface where the groove portion 5 is formed at a close position, the present invention is not limited to this. For example, as shown in FIG. 6A on the surface where the groove portion 5 is formed, and the second position closest to the groove portion 5 on the surface where the groove portion 5 is formed, and on the surface opposite to the surface where the groove portion 5 is formed. 6B, which is the third closest position from the groove 5 and may be formed on the surface where the groove 5 is formed, such as a deformation absorbing portion 6C.

  Furthermore, in the above-described embodiment, three deformation absorbing portions 6 are formed on one side of the groove portion 5 in total, but the deformation absorbing portions 6 are not limited to this. For example, as shown in FIG. Two deformation absorbing portions 6 may be formed on one side, respectively. Further, four or more deformation absorbing portions may be formed on one side of the groove portion, or only one deformation absorbing portion may be formed.

  Moreover, in the said Example, although the planar shape of the edge part of a deformation | transformation absorption part was substantially semicircular arc shape, it is not limited to this, For example, as shown in FIG. 19, it is good also as arc shape longer than a semicircle Moreover, it may be a polygonal shape or the like.
