Summary of the Invention

Problems to be Solved by the Invention

[0004] By the way, when a seat belt reminder or a seat heater is built in a seat, a harness having a connector that is electrically connected to a connector on the vehicle body side is pulled out from the seat. In this case, for example, a resin plate is provided on the seat side so that the harness does not get in the way during transportation, and the middle part of the harness is temporarily fixed to the plate.

[0005] However, the operation of temporarily fixing the middle part of the harness to the plate is troublesome, and the operation of removing the temporarily fixed harness from the plate without damaging the connector is also a cumbersome operation and difficult to perform quickly. Also, depending on the seat, it may not be possible to provide a resin plate.

[0006] Therefore, the present invention aims to provide a harness temporary holding structure for a seat that allows for quick and easy temporary fastening and removal of the harness. [Means for solving the problem]

[0007] To achieve the above objective, the harness temporary holding structure according to the first embodiment of the present invention comprises a sheet, a harness that is pulled out from the sheet and has a connector at its tip, and a cloth-like holding member that is formed in a cylindrical shape into which the harness can be loosely inserted with the connector at the front, is attached to the surface of the sheet, and is capable of holding the inserted harness.

[0008] According to the first embodiment of the invention, a harness having a connector at its tip is pulled out from the seat. A tubular, fabric-like retaining member is attached to the surface of the seat, into which the harness can be loosely inserted (inserted with some leeway) with the connector at the front. This retaining member is capable of holding the inserted harness. Therefore, even though the harness has a connector at its tip, it is easy to temporarily fasten it to the retaining member and easy to pull out from the retaining member. Thus, the temporary fastening and removal of the harness on the seat can be done quickly and easily. In this invention, "tubular" includes cases where only a portion of the length along the axial direction of the retaining member is tubular.

[0009] Furthermore, a harness temporary holding structure according to a second embodiment of the present invention is a harness temporary holding structure according to the first embodiment, wherein a slit portion is formed in a predetermined region of the holding member that includes the downstream end of the harness in the insertion direction, and the slit portion is aligned with the insertion direction.

[0010] According to the second embodiment of the invention, a slit portion is formed in a predetermined region of the retaining member, including the downstream end of the harness in the insertion direction, along the insertion direction. Therefore, the downstream end of the harness in the insertion direction of the retaining member can be opened wider than the upstream end of the harness in the insertion direction of the retaining member. In other words, even if the harness has a connector at its end, it becomes easier to temporarily fasten it to the retaining member and easier to pull it out from the retaining member. Thus, the temporary fastening and removal of the harness in the sheet can be done more quickly and easily.

[0011] Furthermore, the harness temporary holding structure according to the third embodiment of the present invention is the harness temporary holding structure according to the second embodiment, wherein the length of the slit portion is longer than the length of the connector.

[0012] According to the third embodiment of the invention, the length of the slit portion is longer than the length of the connector. Therefore, compared to the case where the length of the slit portion is shorter than the length of the connector, the downstream end of the retaining member in the direction of harness insertion is more easily opened. Thus, the temporary fastening and removal of the harness in the sheet can be done more quickly and easily.

[0013] Furthermore, a fourth embodiment of the harness temporary holding structure according to the present invention is a harness temporary holding structure according to the second or third embodiment, wherein the portion of the holding member excluding the slit portion on the upstream side in the insertion direction of the harness is sewn to the outer layer, and the length of the sewn portion is approximately half the length of the holding member.

[0014] According to the fourth embodiment of the invention, the upstream portion of the retaining member in the direction of harness insertion, excluding the slit portion, is attached to the outer skin by sewing, and the length of the sewn portion is approximately half the length of the retaining member. Therefore, the shape of the slit portion side of the retaining member is effectively maintained compared to the case where the length of the sewn portion of the retaining member is shorter than half the length of the retaining member. [Effects of the Invention]

[0015] As described above, according to the present invention, the temporary fastening and removal of harnesses in a seat can be performed quickly and easily. [Brief explanation of the drawing]

[0016] [Figure 1] This is a schematic rear view showing the harness temporary holding structure according to this embodiment. [Figure 2] This is a schematic side view showing the harness temporary holding structure according to this embodiment. [Figure 3] This is a schematic rear view showing a temporary harness holding structure using a plate, relating to a comparative example. [Modes for carrying out the invention]

[0017] The embodiments of the present invention will be described in detail below with reference to the drawings. For the sake of explanation, in each figure, the arrow UP will indicate the upward direction of the sheet, the arrow FR will indicate the forward direction of the sheet, and the arrow LH will indicate the left direction of the sheet. Therefore, in the following description, unless otherwise specified, the directions of up and down, front and back, and left and right will refer to the up and down, front and back, and left and right directions of the sheet. Also, the left and right direction is synonymous with the sheet width direction.

[0018] As shown in Figures 1 and 2, the harness temporary holding structure 10 according to this embodiment is provided, for example, on a vehicle seat 12. The seat 12 has a seat cushion 14 on which an occupant sits, and the seat cushion 14 is constructed by covering a seat pad 16, which is supported by a seat cushion frame (not shown), with a surface 18.

[0019] Further, the seat 12 incorporates a seat belt reminder and a seat heater not shown in the drawings, and a harness 20 extending from the seat belt reminder and the seat heater is drawn out from the back surface (lower surface) side of the seat cushion 14. A connector 22 is provided at the tip of the harness 20 for electrical connection to a connector on the vehicle body side (not shown). The connector 22 is formed in a substantially rectangular cross-sectional shape that is larger than the outer diameter of the harness 20 when viewed in the extending direction of the harness 20 (see FIG. 2).

[0020] Also, on the back surface (lower surface) side of the seat cushion 14 and at one end side in the seat width direction of the skin 18 on the rear side, a cloth-like (carpet-like) holding member 24 is formed into a cylindrical shape of a predetermined length by sewing and attached. The holding member 24 is provided such that its axial direction is along the seat width direction. A predetermined region including the outer end portion in the seat width direction (the downstream end portion in the insertion direction of the harness 20) on the rear side of the holding member 24 is not sewn to the skin 18.

[0021] In other words, the holding member 24 is sewn to the skin 18 only in a predetermined region including the inner end portion in the seat width direction (the upstream end portion in the insertion direction of the harness 20) on the rear side (hereinafter referred to as "sewn portion 28"), and a slit portion 26 along the seat width direction (the insertion direction of the harness 20) is formed in the remaining region. That is, a predetermined region including the outer end portion in the seat width direction of the holding member 24 is formed in a substantially "C" - shaped cross section and is configured to be expandable more than a predetermined region including the inner end portion in the seat width direction of the holding member 24 (see FIG. 2).

[0022] Note that the holding member 24 is formed longer than the length of the connector 22 so that at least the connector 22 is always hidden when the harness 20 is inserted. Also, the length of the sewing portion 28 in the holding member 24 is set to approximately half the length along the axial direction of the holding member 24 so that the shape (substantially "C" - shaped in cross - section) on the slit portion 26 side of the holding member 24 is maintained (see FIG. 1). Thus, in the "tubular shape" in the present embodiment, those in which only a part of the length along the axial direction of the holding member 24 is tubular are included.

[0023] Also, the length of the slit portion 26 is formed longer than the length of the connector 22. And the inner diameter of the holding member 24 is formed several times larger than the outer shape of the connector 22 when viewed from the extending direction of the harness 20 (axial direction of the holding member 24). Therefore, the harness 20 can be loosely inserted (inserted with a margin) from the inner - end portion (opening) in the sheet - width direction of the holding member 24 with the connector 22 at the head. That is, the harness 20, including the connector 22, is easy to insert into and pull out from the holding member 24, and is configured to be temporarily fixed (temporarily held) to the holding member 24 simply by being inserted.

[0024] Next, the operation of the harness temporary - holding structure 10 according to the present embodiment configured as described above will be described.

[0025] First, a comparative example shown in FIG. 3 will be described. On the back (rear) side of the seat cushion 14 of the seat 12, a rectangular - flat - plate - shaped resin plate 30 whose sheet - width direction is the longitudinal direction is attached. This plate 30 has a plurality (for example, two) of harness clips 32, and an operator temporarily fixes (temporarily holds) the middle portion of the harness 20 to the harness clip 32 so that the harness 20 does not get in the way during transportation of the seat 12, for example.

[0026] However, the process of temporarily fastening (temporarily holding) the middle portion of the harness 20 to the harness clip 32 of the plate 30 was cumbersome, and the process of removing the temporarily fastened harness 20 from the plate 30 without damaging the connector 22 was also complicated and difficult to perform quickly. Furthermore, in some cases, it was not possible to install the resin plate 30 depending on the sheet 12.

[0027] In contrast, in the harness temporary holding structure 10 according to this embodiment, as shown in Figures 1 and 2, a fabric-like holding member 24 is attached to the back (bottom) side of the seat cushion 14, and to one end of the upholstery 18 in the seat width direction at the rear side, by sewing into a cylindrical shape. Therefore, the harness 20 can be easily temporarily fastened (temporarily held) by simply inserting it into the holding member 24 with the connector 22 at the front. In other words, with such a holding member 24, the harness 20 is easier to temporarily fasten (temporarily held) compared to the comparative example.

[0028] When the harness 20 is temporarily held by the holding member 24, for example, during the transport of the sheet 12, the harness 20 can be prevented from getting in the way, and the swinging of the connector 22 can be suppressed, thereby preventing or suppressing damage to the connector 22. Furthermore, a continuity test for the connector 22 can be easily performed with the harness 20 temporarily held by the holding member 24.

[0029] Furthermore, the harness 20, which is temporarily held in place by the retaining member 24, includes the connector 22 and is loosely inserted into the retaining member 24. Therefore, even with the connector 22, it is easy to pull it out of the retaining member 24. Consequently, even if a worker connecting (wiring) the connector 22 to the vehicle body connector in a later process pulls the harness 20 forcefully and roughly out of the retaining member 24, the harness 20 (connector 22) will detach smoothly from the retaining member 24, preventing or suppressing damage to the connector 22.

[0030] Furthermore, a predetermined area of ​​the retaining member 24, including the outer end in the seat width direction (the downstream end in the insertion direction of the harness 20), is not sewn to the surface 18 and is formed in a roughly "C" shape in cross-section. In other words, a slit portion 26 is formed in the predetermined area of ​​the retaining member 24, including the outer end in the seat width direction (the downstream end in the insertion direction of the harness 20), along the seat width direction (the insertion direction of the harness 20).

[0031] Therefore, a predetermined area of ​​the retaining member 24, including the outer end in the sheet width direction (the downstream end in the insertion direction of the harness 20), can be expanded more than a predetermined area of ​​the retaining member 24, including the inner end in the sheet width direction (the upstream end in the insertion direction of the harness 20). In other words, even though the harness 20 has a connector 22 at its tip, it is easier to temporarily fasten (insert) it into the retaining member 24 and easier to pull out from the retaining member 24. Thus, the temporary fastening and removal of the harness 20 on the sheet 12 can be done more quickly and easily.

[0032] In particular, the length of the slit portion 26 in this embodiment (a predetermined area including the downstream end in the insertion direction of the harness 20) is longer than the length of the connector 22. Therefore, compared to the case where the length of the slit portion 26 is shorter than the length of the connector 22, the downstream end in the insertion direction of the harness 20 in the retaining member 24 can be opened more easily. As a result, the temporary fastening and removal of the harness 20 in the sheet 12 can be performed more quickly and easily.

[0033] Furthermore, since the retaining member 24 can be attached to the surface 18 of the seat cushion 14 by sewing, and does not require a large space for attachment (the sewing portion 28 only needs to be about half the length of the retaining member 24 along the axial direction), there is no risk of the problem occurring where it cannot be installed on the seat 12.

[0034] Furthermore, since the length of the sewn portion 28 of the retaining member 24 (a predetermined area including the upstream end in the insertion direction of the harness 20, and the length of the upstream portion of the harness 20 in the insertion direction excluding the slit portion 26) is approximately half the length of the retaining member 24, the shape of the retaining member 24 on the slit portion 26 side can be effectively maintained compared to the case where the length of the sewn portion 28 of the retaining member 24 is shorter than half the length of the retaining member 24.

[0035] The harness temporary holding structure 10 according to this embodiment has been described above based on the drawings. However, the harness temporary holding structure 10 according to this embodiment is not limited to the illustrated version, and can be modified as appropriate without departing from the spirit of the present invention. For example, in the above embodiment, the stitching that forms the holding member 24 into a cylindrical shape and the stitching that attaches it to the outer skin 18 are common (one) stitches, but the stitching that forms the holding member 24 into a cylindrical shape and the stitching that attaches it to the outer skin 18 may be separate stitches.

[0036] Furthermore, the mounting position of the retaining member 24 on the surface 18 is not limited to the position shown in the figure. Also, the slit portion 26 only needs to be formed in a predetermined area including the downstream end of the harness 20 in the insertion direction of the retaining member 24, and this predetermined area may include the inner end of the retaining member 24 in the sheet width direction. Also, the position where the slit portion 26 is formed may be on the front side of the retaining member 24 rather than the rear side.

[0037] Furthermore, although the above embodiment described an example in which the retaining member 24 is attached to the surface 18 of the seat cushion 14, the retaining member 24 may also be attached to the surface of the seat back, which is not shown. The mounting position of the retaining member 24 and the position in which the slit portion 26 is formed in the retaining member 24 can be appropriately designed and changed according to the position and length of the harness 20 pulled out from the seat 12.
