TECHNICAL FIELD OF THE INVENTION
The present invention relates to an electric connection structure, an electric connection device, an electric connection device, a seat using the electric connection device, and a harness surplus length absorption device applied to, for example, a seat of an automobile or the like for making an electric connection between two or more members.
[0002]
[Prior art]
At present, many seats of vehicles such as automobiles are equipped with many auxiliary devices such as various electric components such as an electric reclining mechanism and a seat heater. Among them, for example, the seat can be slid forward and backward by an electric motor. Power seats that move vertically up and down are becoming increasingly popular. Normally, a power seat is installed on a floor panel by combining a fixed-side seat rail fixed to a floor panel as a floor material and a movable-side seat rail connected to a seat frame constituting a seat skeleton. A structure in which a desired seat position can be adjusted by sliding the movable seat rail with respect to the fixed seat rail by means of an electric motor mounted on the vehicle and vertically moving the seat frame with respect to the movable seat rail. It is configured to be. For example, power supply to each auxiliary device mounted on such a power seat is performed by electrically connecting a floor-side wire harness routed behind the floor panel and a seat-side wire harness routed to the power seat side. When power is supplied by such a structure, the harness length of the floor side wire harness should be set to a length that can sufficiently correspond to the sliding movement amount of the movable side seat rail. Therefore, when the seat is moved back and forth, the extra length of the floor-side wire harness may be exposed, causing a problem.
[0003]
In order to solve such a problem, there has been known a configuration in which a wiring mode of the floor-side wire harness is devised so that the floor-side wire harness is not exposed as much as possible from the floor material (for example, Patent Document 1). And 2).

[Problems to be solved by the invention]
However, for example, in the power sliding device for an automotive seat described in Patent Document 1, when the seat slides back and forth, it is effective in reducing the exposure of the floor side wire harness, but it is vertically moved vertically. There is no special contrivance, and it is easy to set the wiring harness length of the seat-side wire harness that is routed on the seat side to a length that can sufficiently correspond to the vertical movement amount of the seat frame. Can be guessed. Therefore, when the sheet is vertically moved vertically, the extra length of the sheet-side wire harness may be exposed, causing a problem. Similarly, the harness storage structure described in Patent Literature 2 is effective for sliding the seat back and forth, but has the same risk of causing the same problem in vertical movement. As described above, the above Patent Documents 1 and 2 disclose only the point of sliding in one direction, and the movements in a plurality of different directions (for example, the sliding direction and the vertical direction) are described. No action has been taken. Further, in both of Patent Literature 1 and Patent Literature 2, since the connection point between the floor side wire harness and the seat side wire harness is a fixing point on the seat side, a long panel for moving the floor side wire harness is provided on the floor panel. A slit must be formed, and since the floor-side wire harness is routed behind the floor panel, a wiring space for the floor-side wire harness must be secured mainly behind the floor panel. For this reason, in the former case, dust or dirt enters through the long slits, causing troubles. In the latter case, securing an appropriate interior space (for example, the height of the seat occupant from the roof panel to the roof panel and the floor panel to the floor panel) Higher knee height).
[0006]
The present invention has been made in view of such circumstances, and when applied to, for example, a seat of an automobile or the like, particularly, a power seat, it is possible to minimize the exposure of a floor-side wire harness and to reduce the floor panel. A simple structure, which eliminates the need for a long slit and minimizes the exposure of the extra length of the seat-side wire harness. It is an object to provide an electric connection structure, an electric connection device, a seat using the same, and a harness excess length absorbing device which can be connected to the electric connection structure.
The present invention also provides an electric connection structure, an electric connection device, a seat using the same, and a harness surplus length absorption device which can achieve cost reduction by realizing effective use of the vehicle interior space and simplification of the wiring work. The purpose is to provide.

Become.
[0022]
Auxiliary devices such as various motors mounted on the seat 1 configured as described above are electrically connected to each other by a seat wiring 27 routed to the seating portion 3, as shown in FIGS. In addition, electric supply is performed by being electrically connected to the electric wiring 29 arranged on the floor panel 28 side as the floor material via the connection circuit member 32 of the electric connection device 30. The seat 1 is fixed by, for example, attaching the lower rail 6 to the floor panel 28 via the bracket 31.
[0023]
The electric connection device 30 applied to the sheet 1 is composed of a flat connection strip 32 having flexibility and an L-shaped case 33 along the upper rail 5. A portion other than the first terminal portion 34 and the second terminal portion 35 is housed inside the case portion 33, and the case portion 33 is attached and fixed along the upper rail 5 to move integrally with the upper rail 5. Become. 1 and 2 show a state in which the seat 1 is slid forward, and FIG. 3 shows a state in which the seat 1 is slid rearward.
[0024]
4 and 5 are partially cutaway perspective views for explaining the internal structure of the electric connection device 30 applied to the seat 1. FIG.
As shown in FIGS. 4 and 5, the electric connection device 30 includes a connection circuit member 32 and a case 33. In the electric connection device 30 of this example, the connection circuit member 32 is connected to the sheet wiring 27. A first folded portion 36 formed by bending twice along a flat surface 32a in the central portion of the band shape of the connection circuit member 32 at a position near the first terminal portion 34 to be formed, and an electric wiring 29 And a second folded portion 37 formed by bending once along the flat surface 32a in the central portion of the connection circuit member 32 at a position near the second terminal portion 35 connected to the second folded portion 37. Have been. The first terminal 34 and the sheet wiring 27 are connected by connecting a connector 47 attached to the first terminal 34 to a connector (not shown) attached to the sheet wiring 27, The second terminal section 35 and the electric wiring 29 are connected by connecting the connectors 48a and 48b respectively attached thereto.
[0025]
Further, the connecting circuit member 32 intersects with the longitudinal direction of the central portion of the connecting circuit member 32 at a portion near the first terminal portion 34 and on a side opposite to the first terminal portion 34 side with respect to the first folded portion 36. And a third folded portion 38 formed by folding back once along the flat surface 32a and a portion closer to the second terminal portion 35 than the second folded portion 37 near the second terminal portion 35. The connection circuit member 32 includes a fourth folded portion 39 which is formed by bending once along the flat surface 32a so as to intersect the longitudinal direction of the central portion of the connection circuit member 32.
[0026]
The connection circuit member 32 is formed by patterning a conductive material such as a copper foil on an insulating film (not shown) such as polyethylene terephthalate (PET), polyethylene naphthalate (PEN), and polyimide (PI). A flexible printed circuit (FPC) having a structure in which a circuit portion (not shown) is formed, and a coverlay (not shown) made of a synthetic resin or the like is formed on the insulating film and the circuit portion as required, or the above-described circuit portion A flexible flat circuit (FFC) formed by stamping and forming a flexible flat cable (FFC) having a structure in which a circuit section is formed by extruding a conductor, and the circuit section is laminated with an insulating film. ing.
[0027]
The connection circuit member 32 is formed by stacking at least two of the flexible printed circuit, the flexible flat circuit, and the flexible flat cable, by stacking a plurality of each, or by stacking a plurality of each. At least two of the combinations may be further overlapped. If the connection circuit members 32 are configured by being overlapped, the number of connection circuits can be increased without increasing the width (circuit width) of the connection circuit members 32 in the short direction.
[0028]
On the other hand, the case portion 33 is made of, for example, a resin molded member, and in this example, is made up of a plurality of case members of a first case 33a and a second case 33b having a detachable structure. , 33b are fitted (coupled) to form an L-shaped case portion 33. A portion of the connection circuit member 32 excluding the first and second terminal portions 34 and 35 is accommodated in a case space 33c formed by the first and second cases 33a and 33b.
[0029]
In addition, on one side (the second case 33b side in this example) of the first and second cases 33a and 33b, a predetermined portion of a central portion between the first and second folded portions 36 and 37 of the connection circuit member 32 is provided. A fixing portion 40 is provided for fixing the position and supporting the connection circuit member 32 with at least a part of the central portion fixed to the upper rail 5. The connection circuit member 32 is attached and fixed through a formed hole (not shown).
[0030]
Note that, in the case portion 33 of this example, a plurality of slits for exposing the first and second terminal portions 34 and 35 of the connection circuit member 32 housed in the case space 33c to the outside from the case space 33c. Portions 41 and 42 are formed, and the first terminal portion 34 can be moved by a predetermined length with respect to the case portion 33 in the direction of arrow B in FIG. The first folded portion 36 housed in the space 33c is always urged in the direction opposite to the direction in which it is pulled out by the spring force of the first folded portion 36 itself and automatically returns.
[0031]
That is, the first terminal portion 34 has a structure that can be expanded and contracted in the direction of arrow B in the drawing on the first terminal portion 34 side of the first folded portion 36. For example, when the first terminal portion 34 is moved in the direction of arrow B in the drawing so as to be pulled out from the slit portion 41, the radius of curvature of the first folded portion 36 in which an S-shape is drawn becomes smaller than the radius of curvature before drawing out. A force is generated to return the reduced radius of curvature to the original radius of curvature, and the force is a force to return the drawn-out portion of the first terminal portion 34 in the direction of arrow B in the drawing to realize a self-return operation. I do.
[0032]
In this case, at least a part of the band-shaped central portion between the second folded portion 37 and the third folded portion 38 of the connection circuit member 32 is fixed to the case portion 33 by the fixing portion 40. Does not shift with respect to the case portion 33. Further, thereby, the second terminal portion 35 of the connection circuit member 32 can move relative to the case portion 33 via the slit portion 42 in the direction of arrow D in the figure by the slit length of the slit portion 42. The structure is that the case part 33 actually moves since the second terminal part 35 is fixed to the lower rail 6 side (the same applies hereinafter). Note that the slit portions 41 and 42 of this example are provided with a cushioning material 49 so that the first and second terminal portions 34 and 35 do not rub against the openings of the slit portions 41 and 42 when moving. I have.
[0033]
In the seat 1 to which the electric connection device 30 configured as described above is applied, the front vertical motor 15, the rear vertical motor 17, and the slide motor 24 of the seat 1 are driven as shown in FIGS. When the seat frame 9 is vertically moved with respect to the upper rail 5 in the direction of arrow B in the figure, and the upper rail 5 is slid with respect to the lower rail 6 in the direction of arrow D in the figure, the connection circuit of the electric connection device 30 is also provided. Since the first and second terminal portions 34, 35 of the member 32 can move along with vertical and sliding movements while absorbing excess lengths in the respective movement directions without being exposed more than necessary, The exposed portion of the connection circuit member 32 from the case 33 can be minimized.
[0034]
That is, when the vertical movement and the slide movement as described above are performed, the first terminal portion 34 expands and contracts in the direction of arrow B in the drawing with respect to the case portion 33, and the first folded portion 36 becomes a strain absorber and becomes a connection circuit. In addition to absorbing the extra length of the member 32, the second terminal portion 35 uses the band-shaped central portion of the connection circuit member 32 in the direction of arrow D in FIG. And move relatively.
[0035]
For this reason, according to the sheet 1 to which the electric connection device 30 is applied, compared to a sheet 1 in which a long slit is formed in a floor panel so that a connection circuit member moves with the movement of the sheet as in the related art. Problems such as biting and vibration of the connection circuit member caused by excessive exposure of the connection circuit member can be reduced as much as possible, and the seat 1 and the sheet 1 can be formed by eliminating a long slit to be formed in a floor panel or the like. The appearance of the wiring of the harness in the vicinity can be improved. Further, since the electric connection device 30 is attached to the upper rail 5 side, the assemblability of the electric connection device 30 to the seat 1 and the like can be improved.
[0036]
Further, in the electric connection device 30, the extra length of the connection circuit member 32 in the vertical movement can be absorbed, and the relative movement can be made by using the band-shaped central portion of the connection circuit member 32 in the slide movement. As a result, the extra length can be absorbed at the same time by one electric connection device 30. For example, the moving operation in a plurality of different directions can be flexibly dealt with, and the cost related to the extra length absorption measure is reduced. It is possible to do. Furthermore, as described above, since the electric connection device 30 is attached to the upper rail 5 side, the space on the back side of the floor panel 28 is reduced as compared with the case where a harness is routed behind the floor panel 28 as in the related art. As a result, the height of the space inside the vehicle from the floor panel 28 to the roof panel (not shown) can be increased, so that the height of the occupant sitting on the seat 1 can be increased. It is possible to produce a wide and comfortable interior space.
[0037]
Further, according to the electric connection device 30, as in the case of the above-described seat 1, members (for example, the seat frame 9 and the lower rail 6) that are respectively movable relative to a predetermined member (for example, the upper rail 5). The electrical connection between them can be integrated into one system to simplify the work of arranging the connection circuit member 32, and the first terminal portion 34 exposed from the case portion 33 automatically adjusts its length. In order to absorb the extra length or to make the second terminal portion 35 relatively move using the band-shaped central portion of the connection circuit member 32, the extra wiring length is reduced as much as possible, and the conventional wire harness is reduced. Compared with the electrical connection when used, the cover for concealing the wiring and the space for wiring can be minimized, and the exposure of the wiring can be minimized. This makes it possible to electrically connect the seat frame 9 and the lower rail 6 that move with respect to the upper rail 5 at a low cost with a simple structure.
[0038]
【The invention's effect】

Is connected to For this reason, these one and the other ends can be relatively moved with respect to the central portion, respectively. As a result, the electrical connections between a plurality of members moving in different directions are combined into one system, and when the connection circuit members move significantly with the movement of each member, the circuit can be flexibly handled while minimizing the circuit exposure. Electrical connection is possible, and one end of the connection circuit member and the other end of the connection circuit member have a structure that can be relatively moved with the movement of a plurality of members to be connected to each other.
