The armrest rotates clockwise, and the limit switch 447 comes into contact with the stopper pin 445 and is turned on.

Also, when the armrest is lying down or standing up, it is designed to prevent it from rotating any further than when it is lying down or standing up.

This locking mechanism is shown in FIG. The stopper pin 448 consists of the four strami pins 448 provided in the seat back frame 442 and the groove 444a provided in the armrest frame 444. In other words, the stopper pin 448 is always accommodated in the groove 444&, so when the user is standing, The pin 448 is in contact with one end 444bK of the groove 4441 and does not rotate any further. Also, when sleeping, the other end 444
It is in contact with CK and will not rotate any further. Of course, when the stopper bin 448 is in contact with the end 444b, the stopper bin 445 is in contact with the limit switch 446, and the stopper bin 448 is in contact with the other end 444b.
When it is in contact with 44@, the /4 pin 445 is in contact with the limit switch 447.

It is. A horizontal slide function on the left side of the middle opening is added to the basic functions. Besides, it's a full 7.

When the seat is on the left and right, the left and right seats are integrated, which makes it easier to use than before, and the entrance is wider so it can also be used as an entrance. In addition, in the past, getting on and off the last seat and loading and unloading luggage were done through the middle opening, but with the device shown in Figure 1, it can now be done from the door side of the middle seat by sliding the middle opening laterally. It's convenient.

With such a configuration, various operations can be performed by controlling each drive motor and each limit switch.

First of all, the manual operation type S includes seat front and rear i for both the left and right middle seats, seat rotation, reclining standing position,
Sleeping position, headrest vertical movement, armrest standing position,
Sleeping position: - The last seat has seat movement fore and aft, reclining standing position, sleeping position, and left/right headrest operation. The manual switch SW can adjust each part of the 7-toe to any position within the range of each limit switch to best fit the passenger.

Automatic operation is explained below.

Since there are many moving parts, various types of automatic operation switches can be considered. For example, set all seats to full 72, set only any seat to full 72, set the left and right middle seats to face each other, set one of the seats to face each other, or set any seat to full flat or flat. Various automatic operation switches can be considered, such as returning all seats to the normal state, returning any seat to the normal state, horizontally sliding only the middle seat occupied, or adding a lateral slide for the middle seat to each of them.

As an example of the basic functions, Fig. 13 shows a case in which all seats are made completely flat and the middle seats are moved to the inside of the vehicle interior, and Fig. 14 shows a case in which all seats are made to face each other. A flowchart is shown. Control details (motor number, limit switch number instructions) are omitted, and only the general flow is shown.

Further, since the circuit according to the flowchart can be easily constructed using conventional techniques, detailed explanation will be omitted. In FIGS. 13 and 14, each motor is operated until the switch marked with a question mark (?) is turned on.

First, with reference to Figures 12 and 13, while all seats are fully flat, the middle seat is
If there is a configuration diagram, please also include the name and number in the configuration diagram.If there is a configuration diagram, please also include the name and number in the configuration diagram.Use the operation switch to move all seats fully flat and the middle seat to the inside of the vehicle. When the user selects to move to , this signal is sent to the control unit C0NT, and the control unit C0NT controls all the seats to make them fully flat and move the middle seat to the inside of the vehicle interior. The flowchart of the control unit C0NT is the same as shown in FIG.

Details will be explained below. First, lay the middle right seat completely flat. 5IOIK determines whether the middle seat right seat is in the front or facing direction.When the limit switch LS (22) is on, it is the front, and when the LS (21) is on, it is facing, and when it is in the front, it is YES. , When meeting face-to-face, proceed to know.

At 8102-S105*, first, since the right seat is in the facing state, only the right seat is returned to the frontal state. At 5102, the reclining motor MT, (3) is activated and the limit switch LS (31) is turned on/off. Raise the seat back until In 5103, seat front and rear motor M
