On the side, the end portion of the outer cable is hooked and fixed to the first cable hooking plate 23A coupled to the base side frame 23 outside the vehicle, and the end portion of the inner cable is hooked to the arm member 32. And fixed. Further, as shown in FIG. 7, the transmission cable 33 is fixed at the other end 33 </ b> B side by hooking the end portion of the outer cable to the second cable hooking plate 11 </ b> A coupled to the side frame 11 inside the vehicle. The end portion of the inner cable is hooked and fixed to an arm member 34 integrally connected to the operation shaft 31 of the reclining device 30 inside the vehicle.

  9 and FIG. 6, the transmission cable 33 is pulled out from the end of the outer cable on the one end 33 </ b> A side by the operation of rotating the arm member 32. 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.

  Thus, according to the configuration of the vehicle seat 1 of the present embodiment, the release lever 44A is provided by being attached to the outer outer shield 40A (corresponding to the “shield” of the present invention), whereby the release lever 44A. The amount of overhang from the outer outer shield 40A and its movement trajectory can be set based on the outer outer shield 40A. Therefore, the movement locus of the release lever 44A is set so that the amount of protrusion from the outer shape of the outer outer shield 40A is reduced by, for example, following the shape of the outer outer shield 40A, or the release lever 44A and the outer outer shield. The shape and arrangement of each other can be set so that a sufficient amount of operation movement can be ensured without interfering with each other, and the outer outer shield 40A can be made compact while ensuring the operability of the release lever 44A. Can be. In addition, since the operation direction of the release lever 44A is set to the operation direction in which the release lever 44A is pulled backward with respect to the outer outer shield 40A (operation direction pulled up from the front), the operation of the release lever 44A can be performed at a position close to the seated person. Thus, operability can be improved.

  Further, since the release lever 44A is provided attached to the outer outer shield 40A, the same position is always maintained in the same position (same direction, same position) even if the backrest angle of the seat back 2A on the 6 side changes. It is kept in a state where it can be operated in a manner. In this way, the release lever 44A can be arranged with good operability so that the operability does not change even if the backrest angle of the 6-side seat back 2A changes. Further, the opening 41A is formed in the outer outer shield 40A to open a movement space when the release lever 44A is operated, and the shielding lever 44Ae that shields the opening 41A is formed in the release lever 44A. And it can be set as the structure which can make the shielding property by the outer side outer shield 40A compatible.

  Further, by operating the release lever 44A, the arm member 32 disposed in the outer outer shield 40A is pushed and turned so that the locked state of the reclining device 30 is released, so that the release lever 44A and the arm are released. It can be set as the structure which sets the rotation radius of the member 32 each short, and transmits rotational power. Therefore, the release lever 44A and the arm member 32 can each be formed into a compact shape with a good appearance by making the outer outer shield 40A have a short turning radius so as not to protrude from the shape of the outer outer shield 40A.

  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 release lever 44A corresponding to the “operation member” of the present invention is provided by being attached to the outer outer shield 40A corresponding to the “shield” of the present invention. May be provided attached to a base body (base side frame 23 in the above embodiment) to which the shield is attached. In the above-described embodiment, the operation type of the release lever 44A is exemplified as a rotary type, but a specific operation type such as a slide type or a push operation type is not particularly limited. In the above embodiment, the reclining device functioning as a rotation shaft device capable of stopping rotation of the seat back is exemplified as the “mechanism provided in the seat body” operated by the “operation member” of the present invention. The mechanism may be another mechanism such as a mechanism for unlocking various engagement / disengagement mechanisms and a slide mechanism mounted on the vehicle seat. Further, the reclining mechanism provided as the above mechanism may be set only on one side portion of the seat back. Moreover, the operation member should just be provided attached to the sheet | seat main body by which a shield or a shield is assembled | attached, and may be provided protruding from the shape of a shield. Further, the configuration of the vehicle seat of the present invention may be employed in a so-called captain seat for one person.
