When manufacturing such a sheet, the electrical wiring previously routed to the reading lamp and the electrical wiring previously routed to the seat body are connected by a connector at the joint between the reading light and the seat body. It is common to complete electrical wiring. The connector is generally connected by fitting a male member and a female member.

Japanese Patent Laid-Open No. 10-241447

In order to fit or separate the male member and female member of the connector, it is necessary for the operator to hold the male member and the female member in their hands. It is necessary to pull out the mold member from the reading lamp and the sheet main body together with each electric wiring by the length necessary for the work. Therefore, it is necessary to prepare a surplus length that enables the above-described drawing work for each electric wiring. However, such extra length is unnecessary when the connection of the connector is completed, and electric wiring is wasted.
In view of such a problem, an object of the present invention is to shorten the wiring route of the electric wiring when connecting the connector in the electric wiring for connecting the sheet main body portion and the electric component, so that the electric wiring is connected to the connector side by the shortened amount. The extra length of the electrical wiring for connector connection work is suppressed.

1st invention of this invention is an electrical wiring wiring structure of the electrical component attached with respect to the main-body part of a vehicle seat, Comprising: The electrical wiring of the said electrical component is connected to the electrical wiring of the said main-body part via a connector. Either the electrical component or the main body is connected as a routing path through which the electrical wiring passes, in addition to the first routing path in a state where the electrical component is attached to the main body. A wiring path of electrical wiring is formed so as to form a cable path, and the length of the second cable routing path is shorter than that of the first cable routing path.
According to the first aspect of the present invention, when the connector is connected or separated, the wiring route of the electric wiring is set as the second wiring route by using the wiring route of either the electric component or the main body as the second wiring route. The length can be shortened. As a result, the electrical wiring can be extended from either the electrical component or the main body by the amount of the shortened wiring path, and the length of the electrical wiring required for connector connection work can be increased. The extra length of the electrical wiring for ensuring can be suppressed.

According to a second aspect of the present invention, in the first aspect, the electrical component and the main body are mechanically coupled to each other by a coupling portion provided on each of the electrical components and the connector. A wiring passage is formed so as to form a first wiring route, and a work passage that forms a second wiring route is formed adjacent to the wiring passage in one of the coupling portions. The routing path is formed so as to be changeable across both paths between a path passing through the routing path and a path passing through the work path.
According to the second invention, when connecting or separating the connector, the wiring path of the electric wiring can be changed from the wiring path of the connecting portion to the working path, so that the wiring path of the electric wiring can be shortened. Can do. As a result, the same effect as the first invention can be achieved. In addition, when connecting the connector and connecting the connecting parts of the electrical component and the main body part, the electrical wiring drawn out with the connection of the connector is returned, so the wiring route of the electrical wiring is the second routing The route changes from the route to the first route. At that time, the electrical wiring is moved across the passages from the working passage to the routing passage. After the connection of the connector and the connection of each connecting part is completed, the wiring path of the electrical wiring is determined by the other connecting part where the working path is not formed, and the working path is formed in one connecting part. Nevertheless, it is possible to prevent the routing route of the electrical wiring from moving unstable.

Each figure shows an embodiment of the present invention. This embodiment shows an example in which the present invention is applied to a reading lamp (corresponding to an electrical component of the present invention) of a vehicle seat (hereinafter simply referred to as a seat). In each figure, each direction of the sheet is indicated by an arrow. In the following description, the description regarding the direction is made based on this direction.
As is well known, the seat 1 is composed of a combination of a seat back 2, a seat cushion 3, and an armrest 4, and a headrest 23 is provided at a position on the seat back 2 corresponding to the head when an occupant is seated on the seat 1. It has been. The reading lamp 5 is attached to the right side of the headrest 23 at the side position of the seat back 2 (corresponding to the main body of the present invention).

The reading lamp 5 has a long and narrow bar shape, and one end is fixed to the upper right side portion of the seat back 2 and the other end is attached to be inclined so as to face the vicinity of the hand of the seated occupant. In addition, the reading lamp 5 is configured to be freely bent at an intermediate portion in the longitudinal direction. Therefore, the reading lamp 5 is composed of a base portion 51 on the side fixed to the seat back 2, a movable portion 52 on the front end side, and a joint portion 53 that couples them in a relatively rotatable manner. A light emitting unit 54 including a light emitting diode, a lens and the like is provided at the tip of the movable unit 52.
In order to supply power to the light emitting diode of the light emitting unit 54, an electrical wiring 61 is routed through the base unit 51, the joint unit 53, and the movable unit 52 of the reading lamp 5. As a result of such a configuration, the reading lamp 5 allows the occupant seated on the seat 1 to move the movable portion 52 in an arbitrary direction and irradiate the light emitted from the light emitting portion 54 to a desired place.

Next, a structure for attaching the reading lamp 5 to the seat back 2 will be described.
A bracket 22 is fixed to the right shoulder of the back frame 21 that forms the skeleton of the seat back 2, and a base portion 51 of the reading lamp 5 is attached via the bracket 22. Specifically, the bracket 22 includes a support portion 22A that is fixed to the back frame 21, and a rectangular tube-shaped coupling portion 22B that is integrally formed with the support portion 22A and protrudes in the mounting direction of the reading lamp 5. Yes. Further, the base portion 51 of the reading lamp 5 is formed with a fitting hole 51C (corresponding to one coupling portion of the present invention) for receiving the coupling portion 22B of the bracket 22, and is fixed adjacent to the fitting hole 51C. The part 51B is integrally formed. Therefore, the reading lamp 5 is obtained by fitting the coupling portion 22B of the bracket 22 into the fitting hole 51C of the base portion 51, penetrating the fixing portion 51B, and fastening a bolt (not shown) to the support portion 22A of the bracket 22. The base portion 51 is fixed to the back frame 21. Note that, at three locations around the fitting hole 51C of the base portion 51, when the coupling portion 22B is fitted into the fitting hole 51C, the guide piece 51A is in contact with the outside of the coupling portion 22B. And is integrally formed. The guide piece 51A has a function of guiding the fitting start position when the coupling portion 22B is fitted into the fitting hole 51C.

  In the state where the reading lamp 5 is fixed to the back frame 21 in this way, as shown in FIG. 3, the base portion 51 of the reading lamp 5 comes into contact with the right keratin portion of the seat back 2, and the movable portion 52. Is free to move around without any obstacles. Further, the back board 24 on the back surface of the seat back 2 is positioned in contact with a corner portion formed by the base portion 51 and the coupling portion 22B.

Next, electrical wiring will be described.
In order to supply power to the reading lamp 5, electrical wiring 62 is routed to the back frame 21 from a vehicle-mounted power circuit (not shown). The electrical wiring 62 is connected to the electrical wiring 61 of the reading lamp 5 through the connector 63 through the wiring passage 22B1 (corresponding to the other coupling portion of the present invention) in the rectangular tube of the coupling portion 22B of the bracket 22. Yes. Specifically, the electrical wiring 62 includes an upper electrical wiring 62A and a lower electrical wiring 62B, and both are connected by a connector 64. The connector 64 includes a female member 64A and a male member 64B. The female member 64A is connected to the upper electric wiring 62A, and the male member 64B is connected to the lower electric wiring 62B.

  FIG. 10 shows how the upper electrical wiring 62A is routed to the bracket 22. The upper electrical wiring 62A is routed to the bracket 22 in the procedure of FIGS. 10 (A) to 10 (C). First, as shown in FIG. 10A, the upper electric wiring 62A is a male type connector 63 from the outside of the support 22A to one of the two openings 22A1 formed in the support 22A of the bracket 22. The member 63B is inserted as indicated by an arrow at the top. Next, as shown in FIG. 10B, the male member 63B at the end of the upper electric wiring 62A is passed through the routing passage 22B1 of the coupling portion 22B of the bracket 22 as indicated by an arrow.

In this case, the upper electric wiring 62A is constituted by passing a wire 62A1 in a pipe 62A2 made of a resin mesh material, and has an elastic force so as to give a restoring force to the bending deformation of the upper electric wiring 62A. ing. Therefore, when the upper electric wiring 62A is bent with respect to the bracket 22 as shown in FIG. 10B, the upper electric wiring 62A is easily engaged with the bracket 22 by the restoring force of the pipe 62A2. It is assumed that it cannot be removed.
A male member 63B of the connector 63 is provided at the tip of the upper electric wiring 62A, and a female member 64A of the connector 64 is provided at the rear end of the upper electric wiring 62A. Therefore, when the upper electrical wiring 62A moves so as to come out from the opening 22A1 or the coupling portion 22B of the bracket 22 after the upper electrical wiring 62A is bent and arranged with respect to the bracket 22 as shown in FIG. The male member 63B and the female member 64A are locked to the opening 22A1 of the bracket 22 or the edge of the coupling portion 22B, so that the upper electrical wiring 62A can be prevented from being detached from the bracket 22.
The pipe 62 </ b> A <b> 2 also has a function of protecting the wire 62 </ b> A <b> 1 so that the wire 62 </ b> A <b> 1 contacts the bracket 22 and is not damaged even when the upper electrical wiring 62 </ b> A is engaged with the bracket 22.

  Thereafter, as shown in FIG. 10C, the support portion 22A of the bracket 22 is attached to the back frame 21 with a plurality of bolts 22C. At this time, the upper electrical wiring 62A is sandwiched between the front surface of the back frame 21 and the back surface of the support portion 22A of the bracket 22. Further, since the opening 22A1 of the support portion 22A of the bracket 22 is opened from the side surface of the support portion 22A to the top surface, there is a manufacturing error and the back surface of the back frame 21 and the back surface of the support portion 22A of the bracket 22 are present. Even if the gap between the upper electric wiring 62A and the upper electric wiring 62A becomes narrower, the upper electric wiring 62A is routed with a margin through the large opening 22A1. The other opening 22A2 of the support portion 22A of the bracket 22 is formed to reduce the weight of the bracket 22.

  As described with reference to FIG. 10B, the upper electric wiring 62A is in a state where it cannot be easily detached when engaged with the bracket 22 by the restoring force of the pipe 62A2. As described above, when the work of attaching the bracket 22 to the back frame 21 is performed, it is not necessary to hold the upper electrical wiring 62A so as not to be detached from the bracket 22, and workability can be improved. In addition, since the upper electric wiring 62A is integrated with the bracket 22, the work of fixing with a clip or the like can be eliminated.

FIG. 12 shows how to connect the above-described upper electric wiring 62A and the electric wiring 61 of the reading lamp 5, and the connection work is performed according to the procedure of FIGS. 12 (A) to 12 (D). First, as shown in FIG. 12A, before the reading lamp 5 is attached to the bracket 22 fixed to the back frame 21, the upper electric wiring 62A that is routed so as to protrude from the coupling portion 22B of the bracket 22 is provided. The female member 63A at the tip of the electrical wiring 61 of the reading lamp 5 is connected to the male member 63B of the connector 63. At this time, the wiring route of the electrical wiring 61 inside the base portion 51 of the reading lamp 5 is changed.
Specifically, as shown in FIG. 9, a work passage 51E is formed in the base portion 51 of the reading lamp 5 adjacent to the fitting hole 51C (also a routing passage), and the fitting hole 51C. A communication passage 51D (included in the work passage of the present invention) is formed to make the work passage 51E a continuous passage. As described above, the electrical wiring 61 is routed through the fitting hole 51C, but the routing route can be changed so as to pass through the work passage 51E as necessary. In FIG. 12A, the electrical wiring 61 is routed through the fitting hole 51C together with the female member 63A of the connector 63 (corresponding to the first routing route of the present invention) and then through the work passage 51E. The state of changing to a routed state (corresponding to the second route of the present invention) is indicated by an arrow. In the process of this change, the electric wiring 61 is moved across the passage from the fitting hole 51C (one routing passage) like a single passage through the communication passage 51D to the working passage 51E. FIG. 11 shows a state where the routing route is changed so that the electrical wiring 61 passes through the work passage 51E.

  Thus, when the electrical wiring 61 is routed through the work passage 51E, the routing route is shortened compared to the case where the electrical wiring 61 is routed through the fitting hole 51C, and the reading light 5 is reduced by the shortened amount. The length of the electric wiring 61 drawn out from the base portion 51 is increased. As a result, workability when fitting the female member 63A and the male member 63B of the connector 63 can be improved. That is, since the electric wiring 61 is largely drawn out from the base portion 51, the operator can easily hold the female member 63A in the hand, and the workability is improved. Moreover, at this time, the electrical wiring 61 is pulled out from the base portion 51 by changing the routing route in the base portion 51 of the electrical wiring 61 from the route via the fitting hole 51C to the route via the work passage 51E. Therefore, it is not necessary to set a surplus length for the electrical wiring 61 in the reading lamp 5 in order to pull out the electrical wiring 61 from the base portion 51, and it is not necessary to use an extra electrical wiring 61 for providing the surplus length. However, the pull-out length of the electrical wiring 61 from the base portion 51 due to the change of the wiring path of the electrical wiring 61 is not sufficient to perform the operation of fitting the female member 63A and the male member 63B of the connector 63. In this case, it is necessary to set a surplus length for the electric wiring 61 in the reading lamp 5 in order to secure the insufficient drawer length.

  In order to pull out the electrical wiring 62 from the coupling portion 22 </ b> B of the bracket 22, it is necessary to set an extra length for the electrical wiring 62 in the seat back 2 below the bracket 22. However, if the present invention is applied to the connecting portion 22B of the bracket 22 to form a notch so that the routing route of the electric wiring 62 can be changed to the side of the connecting portion 22B, the electric power of the reading lamp 5 can be changed. As in the case of the wiring 61, the electrical wiring 62 can be connected well without providing a surplus length. However, when forming a notch in the coupling portion 22B in such a manner, care must be taken so that the mechanical strength of the coupling portion 22B is not insufficient.

FIG. 12B shows a state where the connection of the connector 63 is completed. In this state, a urethane tape 65 as a cushioning material and a gap filling material is wound around the outer peripheral surface of the female member 63A of the connector 63. Next, as shown in FIG. 12C, the connector 63 together with the urethane tape 65 is pushed into the rectangular tube of the coupling portion 22 </ b> B of the bracket 22. At this time, the electrical wiring 62 drawn out from the coupling portion 22B of the bracket 22 is also returned into the coupling portion 22B. Thereafter, as shown in FIG. 12D, when the base portion 51 of the reading lamp 5 is brought close to the coupling portion 22B of the bracket 22, the electric wiring 61 is returned into the base portion 51 of the reading lamp 5, and accordingly. As a result, the routing route of the electrical wiring 61 of the reading lamp 5 is returned from the work passage 51E to the fitting hole 51C. As a result, the routing route of the electrical wiring 61 in the base portion 51 of the reading lamp 5 is returned from the second routing route to the first routing route, so that the electrical wiring protruding from the base portion 51 of the reading light 5 The length of 61 becomes shorter. Thereafter, as described above, the front end of the fixing portion 51B of the base portion 51 is brought into contact with the support portion 22A of the bracket 22 and bolted, thereby connecting the electrical wiring 61 of the reading lamp 5 and connecting the bracket 22 to the bracket 22. Installation is complete.
The above description is a case where the connector 63 is connected and the reading lamp 5 is attached to the bracket 22. However, when the reading lamp 5 is detached from the bracket 22 and the connector 63 is disconnected, the above-described work process is reversed.

As described above, when connecting the connector 63 for connecting the electrical wiring 61 of the reading lamp 5 to the electrical wiring 62 on the back frame 21 side, the electrical wiring is provided in the work passage 51E provided in the base portion 51 of the reading lamp 5. By passing 61, the routing route of the electrical wiring 61 can be shortened. As a result, the length of the electrical wiring 61 that is drawn from the base portion 51 of the reading lamp 5 can be increased by the shortened wiring route, and the extra length of the electrical wiring 61 for connecting the connector 63 is increased. The waste of the electrical wiring 61 can be suppressed.
Further, in order to shorten the wiring path of the electric wiring 61, the wiring path through which the electric wiring 61 should originally pass is changed from the fitting hole 51C to the working path 51E, but the connection of the connector 63 is completed. In a state where the base portion 51 of the reading lamp 5 and the coupling portion 22B of the bracket 22 are coupled, the routing route of the electric wiring 61 is determined by the coupling portion 22B of the bracket 22, and the work path is connected to the base portion 51 of the reading lamp 5 Even though the 51E is formed, it is possible to prevent the routing route of the electrical wiring 61 from moving unstable.
