However, since the changeover switch 39 is provided, there is a relationship between the changeover switch 39 and the changeover switch 34.

When the contacts of the changeover switches 34 and 39 are respectively switched to the independent operation side of the solid line a position, an upward or downward current flows through each motor 17a, motor 17b, and motor 17c independently. , right seat 2, middle seat 3, and left seat 4 move up and down independently.

Next, if only the interlocking changeover switch 39 is switched to the interlocking operation side at position b indicated by the dotted line, the middle seat 3
The left seat 4 is rotated independently by switches 35 and 36.

Next, when the changeover switch 34 is also switched to the b position, the left seat 4 is moved up and down based on the middle seat 3, which has been moved up and down based on the right seat 2.

Next, when the heights of the right seat 2, middle seat 3, and left seat 4 are different, if both the interlocking changeover switches 34 and 39 in FIG. 7 are switched to the interlocking operation side of position b. , switch 22 or switch 2 of the position detection switch 21 located between the right seat 2 and the middle seat 3
3 is immediately turned on, and the motor 17b
The middle seats 3 are aligned with the right seat 2 as the reference.
Position detection switch 2 located between middle seat 3 and left seat 4
Either switch 22 or switch 23 of No. 1 is turned on immediately, and the motor 17c is energized.
The middle seat 3 and the left seat 4 are arranged with the right seat 2 as a reference.

In addition, it is possible to configure one of the right seat 2, middle seat 3, and left seat 4 to be a reference specified seat, the other to be an unspecified seat, and to arrange the unspecified seats based on the specified seat. Of course it is possible.

(Example of the reclining device shown in FIG. 8) When the backrest frame 47 of each rear seat is rotated back and forth by the rotation of the motor 17 and the interlocking changeover switch is switched, the position detection switch and the position detection body move the backrest frame 47 forward and backward in conjunction with each other.
