The operation movement amount is transmitted to the other end 33B side shown in FIG. 7, and the arm member 34 connected to the operation shaft 31 is pulled by the inner cable on the other end 33B side. The locked state of the reclining device 30 on the same side is also released.

  Thus, the locking state of the reclining device 30 inside the vehicle is not the connecting rod but the operating force of the release lever 44A via the transmission cable 33 connected to the arm member 32 outside the vehicle operated by the release lever 44A. Compared to the configuration in which the operation shafts 31 of the reclining devices 30 are connected to each other by a connecting rod so that the operation force is transmitted. There are the following merits.

  That is, with reference to FIG. 4, when considering a configuration in which the operation shafts 31 of the reclining devices 30 on both sides are connected to each other by a connecting rod, for example, a front collision of the vehicle occurs and a seat back on the 6 side When a heavy object such as a wine case collides with the side portion (side frame 11) of the vehicle inner side of 2A from behind, the same side (rear side of the vehicle) via the reclining device 30 (locked state) on the same side. The base side frame 23 integrated with the side frame 11 is deformed so as to be crushed in a manner of buckling to the front lower side under a strong compressive force in the bending direction. Due to this deformation, the reclining device 30 in a locked state integrated with the base side frame 23 is rotated forward by the deformation of the base side frame 23 and is held by the operation shaft 31 of the reclining device 30 outside the vehicle. Rotate forward with respect to the connecting rod. This forward rotational movement with respect to the connecting rod is a rotational direction in which the locked state of the reclining device 30 inside the vehicle is released, and the locked state of the reclining device 30 on the same side (inside the vehicle) is released. There is a risk that.

  However, in the configuration of the present embodiment, the operation force is transmitted from the release lever 44A to the operation shaft 31 of each reclining device 30 through the arm members 32 and 34 and the transmission cable 33. The release operation associated with the occurrence of unexpected power transmission as described above is prevented from occurring. Further, as described above with reference to FIG. 9, the release lever 44A and the arm member 32 are configured separately, and the arm member 32 is rotated by being pushed by the operation of the release lever 44A. Compared to those that are configured integrally or connected to each other, the variation in the construction of both the release lever 44A and the arm member 32 is more easily absorbed by the gap between the two installations. The structure is easy to assemble. Also, it is possible to easily set play in the initial rotation region of the release lever 44A so as not to affect the rotation of the arm member 32.

  By the way, although the operation for releasing the lock state of both the reclining devices 30 can be performed by the operation of the remote lever Rc described above with reference to FIG. 3, the specific configuration thereof is as follows. . As shown in FIGS. 10 and 6, when the remote lever Rc is operated, the cable mechanism routed through the side wall portion of the vehicle body and the floor F (not shown) is operated, and the arm member 32 is connected to the arm member 32 described above. The operation portion 35C of the other end 35B of the remote operation cable 35 to which 35A is connected is pulled. Here, the above-described remote operation cable 35 also has a double cable structure in which a linear inner cable is inserted inside a tubular outer cable, similarly to the transmission cable 33 described above. As shown in FIG. 6, at the one end 35 </ b> A side, the end portion of the outer cable is hooked and fixed to the first cable hooking plate 23 </ b> A described above, and the end portion of the inner cable is hooked to the arm member 32. And fixed. The remote operation cable 35 is fixed on the other end 35B side by fitting the end of the outer cable into a semi-cylindrical cable hook 45A formed on the outer outer shield 40A. The operation unit 35C that is pulled by the cable mechanism (not shown) is held at a position that is extended from the end of the outer cable.

  10 and 6, when the remote lever Rc is operated and the remote operation cable 35 is pulled, the arm member 32 is rotated and the reclining device 30 on the outside of the vehicle is locked. Is released, and the locked state of the reclining device 30 inside the vehicle is also released via the transmission cable 33 described above. At this time, the arm member 32 is operated by the remote operation cable 35, and the release lever 44A is not operated. Therefore, the locked state of both reclining devices 30 can be released by operating the remote lever Rc while leaving the release lever 44A in the initial position before the operation.

  By the way, the transmission cable 33 described above is in a state of being bent and routed with respect to the back frame 10 as follows. That is, as shown in FIGS. 4 to 5, the transmission cable 33 is connected to the above-described one end 33 </ b> A connected to the arm member 32 on the vehicle outer side (the left side in the drawing) and the arm member 34 on the vehicle inner side (the right side in the drawing). The cable portion between the other end 33B is curved by being bent in the width direction and the height direction so as to draw a gentle curve in an S shape inside the main frame 10A of the back frame 10. Routed in state. As described above with reference to FIG. 6, the above-described routing causes the transmission cable 33 to suddenly apply an operating force in which the one end 33 </ b> A, which is connected upward to the arm member 32 outside the vehicle, is pulled and operated. Without being bent to the other end 33B which is connected to the arm member 34 on the vehicle inner side described above in FIG. Yes.

  Specifically, as shown in FIG. 5, the transmission cable 33 has an outer tubular outer cable that guides the route of the inner cable inserted through the transmission cable 33. From one end 33A fixed to the first cable hooking plate 23A of the frame 23, it is bent back so as to be guided to the in-frame region of the main frame 10A through the rear side of the back frame 10 (first bending portion 33P1). From there, as shown in FIG. 5, it is routed so as to extend in the width direction along the base pipe 22 of the base frame 20 described above, and is attached to the fixing clip 22B coupled to the base pipe 22 at this position. Thus, the base pipe 22 is fixed. Then, the outer cable of the transmission cable 33 is bent back from the portion fixed by the fixing clip 22B so as to be bent further upward (second bending portion 33P2), and has a height in the main frame 10A described above. The pad support wire 16A, the board hooking wire 16D, the reinforcing pipe 15, and the pad support wire 16B provided side by side in the direction are extended so as to pass through in the height direction, respectively, and then again inside the vehicle (the right side in the figure). ) (The third bending portion 33P3) and the other end 33B is fixed to the second cable hooking plate 11A coupled to the side frame 11 inside the vehicle, as described above with reference to FIG. It is assumed that it has been routed. Here, the pad support wire 16A, the board hanging wire 16D, the reinforcing pipe 15 and the pad supporting wire 16B provided in the main frame 10A in the height direction respectively correspond to the “hanging wire” of the present invention. To do.

  Specifically, the outer cable of the transmission cable 33 includes a pad support wire 16A, a board hanging wire 16D, a reinforcing pipe, and a middle portion extending upward from the second bending portion 33P2 in the height direction described above. 15 and the pad support wire 16B are arranged so as to meander and bend alternately and bend in the front-rear direction so as to be meandered and routed alternately in the front-rear direction. . As a result, the outer cable of the transmission cable 33 is urged against the pad support wire 16A, the board hooking wire 16D, the reinforcing pipe 15, and the pad support wire 16B described above by the elastic force that is pushed and bent. Each is arranged in a state where it is pressed and fastened.

  Specifically, as shown in FIG. 11, the outer cable of the transmission cable 33 is passed through the rear side of the pad support wire 16A, passed through the front side of the board hanging wire 16D, and is reinforced as shown in FIG. The pipe 15 is passed through the rear side, and as shown in FIG. 13, the front side is passed obliquely so as to pass through the corners of the U-shape of the pad support wire 16 </ b> B. As a result, as shown in FIG. 5, the outer cable of the transmission cable 33 extends in the front-rear direction with respect to the pad support wire 16A, the board hanging wire 16D, the reinforcing pipe 15, and the pad support wire 16B. As a state of being elastically pressed so as not to flutter, a state in which positioning in the front-rear direction is performed is performed.

  Further, as shown in FIG. 11, the outer cable of the transmission cable 33 described above is a wire in which a portion extending in the upward direction from the second curved portion 33P2 described above extends in the height direction of the pad support wire 16A. It is applied to the part in the width direction and is bound and fixed by the tie wrap Tw. As a result, the curved shape of the second bending portion 33P2 is held in a fixed state by the fixing by the tie wrap Tw and the fixing by the fixing clip 22B on the base pipe 22. ing.

  Further, as shown in FIG. 5, the outer cable of the transmission cable 33 has a portion toward the other end 33B that is bent downward toward the vehicle inner side (right side in the figure) at the third bending portion 33P3. The cable portion extending in the height direction on the vehicle outer side (the left side in the drawing) in the third bending portion 33P3 is pushed to the vehicle outer side by the reaction force action caused by the pressing. It is in a state of being subjected to a resilient action that is elastically pushed away. However, the cable part receiving the elastic action to the outside of the vehicle is pressed from the side against the anchor wire 15A provided so as to protrude rearward and obliquely upward from the reinforcing pipe 15 described above. Thus, the movement due to the elastic action toward the outside of the vehicle is regulated. As a result, the outer cable of the transmission cable 33 is in a state in which the third bending portion 33P3 is elastically held by the anchor wire 15A and the side frame 11 on the vehicle inner side as described above, with respect to the back frame 10. Thus, the cable is arranged in a state in which the positioning in the width direction is performed. Here, the anchor wire 15 </ b> A corresponds to the “abutting wire” of the present invention.

  As shown in FIG. 14, the transmission cable 33 arranged in the back frame 10 is connected to the mat-type cushion pad 2 </ b> Aa laid on the front surface of the back frame 10 and the back surface of the back frame 10. The above-described backboard 17 is laid down so as to be sandwiched from the front and rear sides. Here, the backboard 17 corresponds to the “plate material” of the present invention. By this pinching, the transmission cable 33 is pressed against the pad support wire 16A, the board hooking wire 16D, the reinforcing pipe 15, and the pad support wire 16B as described above so as not to flutter in the front-rear direction. It is to be held as a state.

  Incidentally, as shown in FIG. 5, the transmission cable 33 described above has a cable portion from the third bending portion 33P3 to the one end 33A routed through the rear side of the side frame 11 outside the vehicle. As shown in FIG. 5, the side frame 11 (see FIG. 5) is extended from the through hole 17C formed in the lower edge of the cushion pad 2Aa to the outside of the shape of the seat back 2A on the 6 side. ) And the outer outer shield 40 </ b> A outside the vehicle, which is routed from the lower rear side. As a result, as shown in FIG. 15, an extension 2 </ b> Aa <b> 1 for concealing a gap between the cushion pad 2 </ b> Aa and the seat cushion 3 (see FIG. 1) extends rearward. Even if it is formed in a shape, the transmission cable 33 can be extended straight down from the frame of the back frame 10 so that it can be fixed close to the base pipe 22 (see FIG. 5) located directly under the back frame 10. So that it can be routed. In addition, the cable part extended outside from the through hole 17C of the cushion pad 2Aa of the transmission cable 33 described above is formed in the lower part on the back side of the skin material 2Ac covered on the surface of the seat back 2A on the 6 side. The extension portion 2Ac1 extending in a fin shape downward is covered and hidden from the rear side.

  Thus, according to the configuration of the vehicle seat 1 of the present embodiment, the transmission cable 33 includes the plurality of hanging wires (pad support wire 16A, board hanging wire 16D, reinforcing pipe 15, And the pad support wire 16B) are held in a state where they are pushed and bent so as to meander alternately in the front-rear direction so as to be pressed against each of the hook wires by their elastic force. Is done. Thereby, the transmission cable 33 can be fixed to the back frame 10 without using a fastener.

  As mentioned above, although the embodiment of the present invention has been described using one example, the present invention can be implemented in various forms in addition to the above example. For example, in the above embodiment, the back frame 10 of the seat back 2A on the 6 side is illustrated as equivalent to the “seat frame” of the present invention, but the “seat frame” of the present invention is not limited to the frame of the seat back. Further, it may be a seat cushion frame or a headrest frame. Moreover, the structure by which a linear member is wired ranging over the flame | frame of a seat back and the flame | frame of a seat cushion may be sufficient.

  In the above-described embodiment, the transmission cable 33 having a double cable structure is illustrated as the “linear member” of the present invention. However, the “linear member” of the present invention is an electric wiring or other cable. Any linear member may be used as long as it is a flexible linear member. Moreover, in the said Example, the hanging wire (Pad support wire 16A, Board hanging wire 16D, Reinforcement pipe 15, and Pad support wire 16B) by which a linear member (transmission cable 33) meanders alternately is arranged, Although the configuration provided side by side in the height direction with respect to the seat frame (back frame 10) has been illustrated, this arrangement direction (the direction in which the linear members are alternately meandered and routed) You may set in other directions, such as the front-back direction. Further, the hanging wire and the contact wire are not linear but may be planar.
