Roughly, the three-element linear digital actuator 106 includes three solenoids 110. 111. 112 is built in, and each solenoid 110. 111. 112 is a transistor whose emitter is grounded 113. 11,1.
connected to the collector of transistor 113
．． At the base of 114°115 is a timer circuit 116.
117. The output terminals of the timer circuits 116, 117, and 118 are connected to the input terminals of the timer circuits 116, 117, and 118.
As illustrated in FIG. 0, the slide setting switch 119
．． Tilt setting switch 120. An open/close setting switch 121 is connected.

Note that the slide setting switch 119. Inclination a setting switch 120. The output of the open/close setting switch 121 is as shown in FIG. It looks like this.

Slide setting switch 119. Tilt setting switch 120
, open/close setting switch 121 and left steering handle 12
3 is attached near the grip 124 of the left steering handle 123, and the operation switch 122 can be operated in three stages: forward/reverse rotation and stop.

Since the embodiment shown in FIGS. 1 to 14 is configured as described above, when the opening/closing setting switch 121 is operated to mesh the gear 105 with the vIUrb drive gear 91, the slide setting switch 119 When turned on, the output is first transmitted from the timer rotation 117,
Transistor 114 becomes conductive, and solenoid 11
1 operates, the movable piece 107 moves from the third position to the second position, and then an output is transmitted from the timer circuit 116, the transistor 113 becomes conductive, and the solenoid 1
10 operates, the movable piece 107 moves to the first position, and thus the gear 105 meshes with the slide drive gear 89 and is set in the sliding state.

■When the slide setting switch 119 is turned on and the gear 105 is engaged with the slide drive gear 89 as shown in FIG. 8, the backrest 7 cannot be moved forward or backward. I can do it.

In the state shown in FIG. 8, the operation switch 122 is turned on in the forward direction to rotate the operation motor 100 in the forward direction,
When the rotation @ 101 is rotated in the opposite direction, this rotational force is applied to the rotating shaft 101, drive gear 102, gear set pin 103, gear 105, slide driver) 789, gear hit bin 103, gear r82, gear 78, connection terminal 7
5, and the slider connection terminal 2 via the cable 71
5, and in the state shown in FIG. 11, the core @ 71a of the cable 71 and the slide adjustment screw 2G rotate in the counterclockwise direction when viewed from the rear to the front, and the female The screw 28 is pushed forward, and together with this, the slide frame 21, the backrest pivot i31, the backrest board 33, the backrest support frame 35, and the side boat board 51 move forward, and the backrest 7 and The side boat 8 can slide forward.

■Backrest hand - Turn on the tilt setting switch 120, engage the gear 105 with the tilt drive gear 1790, operate the three-element linear digital actuator 106, and then turn on the operation switch 122 in the forward rotation direction. When the rotating shaft 101 is rotated counterclockwise in FIG. 8, the 13th
In the figure, the tilt adjustment screw 39 rotates counterclockwise when viewed from the rear to the front, the female screw 41 is pushed forward as shown in FIG. Pushed forward, the backrest base plate 33 is tilted forward about the shaft 32, and the backrest 7 and side boat 8 are erected forward.

■Nai J support 1iff Turn on the gap setting switch 121, operate the three-element linear digital actuator 106 so that the gear 105 meshes with the opening/closing drive gear 91, then turn on the operation switch 122, and set the rotating shaft. When 101 is rotated in the r1 direction in FIG. 8, the connection terminal 54 at J3 in FIG. The worm wheel 58r and the worm 61r rotate clockwise from the left side of the vehicle body to the right side, and the right worm wheel 52r and the side support board 51r rotate clockwise when viewed from the top to the bottom. f
lH1t moving axis 58j.

The A-Muro 1Jll rotates counterclockwise when viewed from the left side to the right, and the left worm wheel 52J and the side 1 port board 51. Q rotates counterclockwise when viewed from above, and side sabots 1 and 8 are thus opened outward.

In this way, the range VJ setting switch 120, the distance setting switch 121, and the operation switch 122 are appropriately selected and turned on, and the switching gear t794 is appropriately rotated to shift the gear 105 to the slide drive gear 89. Meshing with either tilting drive gear 90 or 91, backless 1~backward sliding movement is poor,
Backrest tilting operating state or side na boat li
? ] IfJ rjh can be set to any of the operating states.

Furthermore, after being set to one of the three types of operating states,
Operation switch 12 depending on rider's riding posture, physique, etc.
Turn 2 on and off in the forward rotation direction, rotate @101 at 51
By rotating in the direction or counterclockwise,
The backrest 7 can be moved back and forth, the backrest 7 can be tilted back and forth, or the side supports 8 can be rotated left and right.

In addition, side supports 8 are provided on both the left and right sides of the backless h 7.
are freely provided to the left and right by 1711 m, so the waist of the rider sitting on the front seat 6 is supported by this side support 8.
Not only can the passenger seated in the rear seat 9 be held snugly between the side supports 8, but also the passenger seated on the rear seat 9 can grip the side supports 8 between both legs or knees.

Furthermore, while the rider is sitting in the riding position on the front seat 6, the backrest The opening and closing state of the side support 8 can be freely adjusted.

In the embodiment illustrated in FIGS. 1-14, a three-element linear digital actuator capable of setting three positions is used.
106 and the operation motor 100 were used to adjust the front and rear positions of the backrests 1-7, the inclination, and the opening and closing of the side supports 8. It is also possible to directly connect one motor to each, and to rotate these motors in forward and reverse directions.

Furthermore, as shown in FIG. 16, the present invention can also be applied to automobile seats.

That is, the fore-and-aft position of the seat 125 and the inclination angle of the backrest 126 can be adjusted separately by motors (not shown), and a seat forward position adjustment switch 128 and a backrest inclination adjustment switch 129 are provided near the steering handle 127.
These adjustments may be made by disposing the switch 128 and 129 and operating the switches 128 and 129.

As described above, in the present invention, the driver can adjust the seat position, backrest position, angle, etc. as appropriate by simply operating the operation switch near the steering member while sitting in the seat. Therefore, the adjustment can be made very easily and appropriately, and the driver can drive in the most suitable posture for steering the vehicle according to his physique and preference.
