That is, when the seat main body 12 is in the operating position range S, both the first switch 61 and the second switch 62 are held in the energized state, and the seat main body 12 is in a position outside the operating position range S. At this time, both the first switch 61 and the second switch 62 are held in a non-energized state.

<About the engine start permission means 70>
The engine start permission means 70 is a means for allowing the engine to be started on the condition that the seat body 12 is within the operation position range S.
As shown in FIG. 6, the engine start permission means 70 is constituted by an electric circuit that drives the starter 75. That is, in the engine start permission means 70, the first switch 61 and the second switch 62 are connected in series to the coil 72 c of the starter cut relay 72. When both the first switch 61 and the second switch 62 are held in the energizable state, the coil 72c of the starter cut relay 72 is energized via the first switch 61 and the second switch 62. . Thereby, the contact 72s of the starter cut relay 72 is closed. For this reason, when the neutral switch 76 is in an energized state (on state) by setting the vehicle mission (not shown) to neutral (or parking), the neutral switch 76 and the contact 72s of the starter cut relay 72 are connected via the neutral switch 76. The coil 71c of the starter relay 71 is energized. As a result, the contact 71s of the starter relay 71 is closed, and the starter 75 can be driven. That is, the engine is allowed to start.
In addition, when at least one of the first switch 61 and the second switch 62 is held in an unenergized state, the coil 72c of the starter cut relay 72 is deenergized and the contact 72s is opened. As a result, the energization of the coil 71c of the starter relay 71 is released, the contact 71s of the starter relay 71 is opened, and the drive of the starter 75 is prohibited.

<About the rotating mechanism 40>
The rotation mechanism 40 is a mechanism that horizontally rotates the seat body 12 and the lifting mechanism 50 on the front / rear slide table 32 of the front / rear slide mechanism 30 from a seating position facing the front of the vehicle to a boarding / alighting position facing the door opening side. is there. As shown in FIGS. 2 and 3, the rotating mechanism 40 includes an outer ring 41 and an inner ring 43 that are fitted so as to be relatively rotatable with a bearing 42 interposed therebetween. The outer ring 41 is fixed to the front and rear slide table 32. Has been. An elevating mechanism 50 is installed on the inner ring 43.
Further, on the front / rear slide table 32, a turning motor (not shown) for rotating the inner ring 43 with respect to the outer ring 41 of the rotating mechanism 40 is installed.

<About the lifting mechanism 50 and the seat body 12>
As described above, the elevating mechanism 50 is installed on the inner ring 43 of the rotating mechanism 40, and in a state where the seat body 12 is horizontally rotated at the passenger seat position of the vehicle M to the boarding / exiting position facing the door opening side. This is a mechanism for moving the seat body 12 up and down between the boarding position and the ground. In FIGS. 2 and 3, the structure of the lifting mechanism 50 is omitted and represented in a box shape.
The seat body 12 is configured to be used as a driver's seat in the passenger compartment and to be used as a wheelchair when the seat body 12 is lowered from the vehicle M.
That is, the lateral slide mechanism 20, the front / rear slide mechanism 30, the rotation mechanism 40, the lifting mechanism 50, and the like described above correspond to the sheet moving mechanism of the present invention. The front / rear slide table 32 and the like to which the switch operating member 64 is attached correspond to the movable portion on the seat body side in the present invention, and the lateral slide mechanism 20 to which the first and second switches 61 and 62 are attached. The lateral slide member 27, the lateral frame 21, and the like correspond to a vehicle-side fixing portion in the present invention.

<About the operation of the vehicle driver's seat 10>
First, the operation of the engine start permission means 70 when the seat body 12 is in the operating position range S will be described.
In the driving position range S, the front / rear slide operation switch (not shown) is operated to operate the front / rear slide mechanism 30, so that the seat body 12 can be moved in accordance with the occupant's body shape as shown in FIG. Can slide back and forth. When the seat body 12 is in the operating position range S, as shown in FIGS. 5B to 5D, the switch operating member 64 presses the operating lever 61b of the first switch 61. No. 1 switch 61 is held in a state in which energization is possible. Further, the switch operation member 64 is separated from the second switch 62 to release the pressing of the operation lever 62b. Therefore, the second switch 62 is held in a state where it can be energized.
In other words, when the seat body 12 is within the operation position range S, both the first switch 61 and the second switch 62 are in a state in which energization is possible.
As a result, the coil 72c (see FIG. 6) of the starter cut relay 72 is energized via the first switch 61 and the second switch 62, and the contact 72s of the starter cut relay 72 is closed. Then, by setting the vehicle mission (not shown) to neutral (or parking), when the neutral switch 76 becomes energized, the coil 71c of the starter relay 71 is energized and the contact 71s of the starter relay 71 is closed. . As a result, the starter 75 can be driven, and the engine is allowed to start.

Next, a procedure for using the seat body 12 in the driving position range S as a wheelchair outside the passenger compartment will be briefly described.
Under the condition that the engine of the vehicle is stopped and the seat belt is removed from the buckle BK, when the dismount switch (not shown) of the seat body 12 is pressed, the front / rear slide mechanism 30 operates to move the front / rear slide table 32, In addition, the seat body 12 and the like on the front / rear slide table 32 move backward from the operation position range S to the backward limit position by the distance X.
When the seat body 12 deviates from the operating position range S, as shown in FIG. 5A, the switch operating member 64 moves away from the first switch 61 to release the operation lever 61b, and the second switch 62 is released. The operation lever 62b is pressed. That is, the first switch 61 is not energized, and the second switch 62 is also not energized. As a result, the energization of the coil 72c (see FIG. 6) of the starter cut relay 72 is released, and the contact 72s is opened. As a result, the energization of the coil 71c of the starter relay 71 is released, the contact 71s is opened, and the drive of the starter 75 is prohibited. That is, even if the starter 75 is operated, the starter 75 is not driven and the engine is not started.
At this time, when only the operation lever 61b of the first switch 61 is held in a pressed state due to foreign matter or the like, only the operation lever 62b of the second switch 62 is held in a pressed state. In this case, and when the operation levers 61b and 62b of both the switches 61 and 62 are held pressed, at least the second switch 62 is in a non-energized state. It is forbidden.
In addition, when only the operating lever 61b of the first switch 61 cannot be pressed due to the drop of the switch or the like, only the operating lever 62b of the second switch 62 cannot be pressed, or the operating levers 61b of both the switches 61 and 62 can be pressed. In any case where 62b cannot be pressed, at least the first switch 61 is in a non-energized state, so that the drive of the starter 75 is prohibited.

Thus, when the seat body 12 and the like are retracted to the retreat limit position, the lateral slide mechanism 20 is operated, and the lateral slide member 27 and the seat body 12 and the like on the lateral slide member 27 are moved to the passenger seat side (left end). Slide laterally by a distance W (see FIG. 4B). Thus, since the seat body 12 slides sideways with the seat body 12 retracted from the driver seat position to the retreat limit position, it is possible to prevent interference between the passenger and the handle.
Next, the front / rear slide mechanism 30 operates to advance the front / rear slide table 32 and the seat body 12 on the front / rear slide table 32 by a distance Y to a rotatable position. Then, the rotation mechanism 40 operates in the state where the door Dr on the passenger seat side is open, and the boarding / alighting position where the seat body 12 and the like turn around the rotation center C from the seating position facing the vehicle toward the door opening side at the rotatable position. Turn about 90 ° to the left. Next, the elevating mechanism 50 is operated, and the seat main body 12 is lowered to the ground with the wheels deployed. The seat body 12 can be used as a wheelchair by releasing the connection between the seat body 12 and the lifting mechanism 50.
When the seat body 12 used as a wheelchair is returned to the driver's seat position, the elevating mechanism 50, the rotating mechanism 40, the lateral slide mechanism 20, and the front / rear slide mechanism 30 operate in the reverse order as described above. .

<Advantages of the vehicle driver's seat 10 according to this embodiment>
According to the present invention, when the seat body 12 is within the operating position range S, both the first switch 61 and the second switch 62 are held in the energized state, and the seat body 12 is out of the operating position range S. When the switch is in the position, the first switch 61 and the second switch 62 are held in an unenergized state. The engine is allowed to start on the condition that both the first switch 61 and the second switch 62 are energized.
For this reason, even if one of the first and second switches becomes energized due to a failure or the like when the seat body is out of the operating position range, both of the other switches must be energized. In this case, since the engine is not allowed to start, the reliability of the engine start permission means is improved.
Further, when only the operation lever 61b of the first switch 61 is held in a pressed state due to foreign matter or the like, only the operation lever 62b of the second switch 62 is held in a pressed state. In this case, and when the operation levers 61b and 62b of both the switches 61 and 62 are held pressed, at least the second switch 62 is in a non-energized state. Is done.
Further, when only the operating lever 61b of the first switch 61 cannot be pressed due to the drop of the switch, etc., only when the operating lever 62b of the second switch 62 cannot be pressed, and the operating levers 61b of both the switches 61 and 62, In any case where 62b cannot be pressed, at least the first switch 61 is in a non-energized state, so that the drive of the starter 75 is prohibited.

<Example of change>
In addition, this invention is not limited to the said embodiment, The change in the range which does not deviate from the summary of this invention is possible. For example, in this embodiment, the switch operation member 64 is provided on the front / rear slide table 32 side of the front / rear slide mechanism 30, and the first switch 61 and the second switch 62 are provided on the side slide member 27 side. However, as shown in FIG. 7A, it is also possible to provide the first switch 61 and the second switch 62 on the front / rear slide table 32 side and the switch operation member 64 on the side slide member 27 side. .
Further, as shown in FIG. 5, the switch operating member 64 directly presses the operating lever 61b of the first switch 61 and the operating lever 62b of the second switch 62 as shown in FIG. B) As shown in (C), the switch operating member 64 is moved by contacting the front and rear slide table 32 provided with the first and second switches 61 and 62, and the first and second switches 61 and 62 are moved. It is also possible to provide first and second intermediate bodies 67 that press 62. Thereby, the dispersion | variation in the relative positional relationship of the 1st and 2nd switches 61 and 62 and the 1st and 2nd intermediate body 67 can be made small. In addition, the first and second intermediate bodies 67 and the switch operation member 64 can be relatively freely set in size and the like in consideration of the relative positional variation. For this reason, the operation levers 61b and 62b of the first and second switches 61 and 62 can be reliably pressed or released.

In the present embodiment, the first switch 61 having a normally open structure is provided at a position where the operation lever 61b is pressed when the seat body 12 is in the operating position range S, and the seat body 12 is out of the operating position range S. In this example, the second switch 62 having a normally closed structure is provided at a position where the operation lever 62b is pressed when the operation lever 62b is pressed. However, as shown in FIG. 8B, a plurality of normally open switches 61 and 62 (for example, two) are provided at positions where the operation levers 61b and 62b are pressed when the seat body 12 is within the operation position range S. ) Can also be provided. In this case, the plurality of switches 61 and 62 are connected in series to the coil 72c of the starter cut relay 72, as shown in FIG. The other configuration of the electric circuit is the same as that of the electric circuit shown in FIG.
Further, as shown in FIG. 9B, a plurality of normally closed switches 61 and 62 (for example, two units) are provided at positions where the operation levers 61b and 62b are pressed when the seat body 12 is out of the operating position range S. ) Can also be provided. Also in this case, the plurality of switches 61 and 62 are connected in series to the coil 72c of the starter cut relay 72 as shown in FIG.
In the present embodiment, an example is shown in which limit switches are used for the first and second switches 61 and 62 and a striker is used for the switch operating member 64. However, a photoelectric switch receiver is used instead of the limit switch. It is also possible to use a photoelectric switch projector instead of the switch operating member 64.
