Abstract

PURPOSE:To augment the safety of crews where a seat is permitted to be shifted as required to special configurations, e.g. the seat can be elevated up closely to the skylight by allowing the seat to be shifted to special configurations only when a car is running at a speed lower than the stated one. CONSTITUTION:In van type cars where a rear seat can be elevated up closely to the skylight by means of a pantograph and others driven by a motor 32, a speed response switch 15 is connected with a ACC contact 10C of an ignition switch 10 through an accel switch 11 which is turned on at a time when entirely closed. Here, the speed responseswitch is turned on when the speed detected by a speed detecting device (not shown) is zero. And when the switches 11 and 15 are turned on, that is, when a manual switch 21 is turned on while the car stops, NO.1 through NO.3 excitation switches 24, 28, and 37 are to be configurated as shown in the figure enabling a fed circuit U for the seat elevation to be established. Under this condition, a seat 32 is driven with an electric current applied to the direction of A allowing the rear seat to be ele vated.

The elevating and lowering operation of the rear seat 5B will be explained as follows based on this circuit configuration.

Here, the solid line in Figure 2 is the rear sea) 5B is on top! 1, and the broken line shows the operating state when the rear seat 5B is lowered.

First, when the rear seat 5B is raised, that is, when the manual switch 17 is turned on, the vehicle speed response switch 15 connected to the ignition switch 10 is turned on.
Depending on whether or not the vehicle speed response switch 15 is ON (
If it is OFF (broken line), it will rise; if it is OFF (broken line), it cannot rise.

That is, the vehicle speed response switch 15 is turned ON when the vehicle speed detecting means (FIG. 1) 16 detects that the vehicle speed has become O. When this vehicle speed is O, that is, when the manual switch air is turned ON while the vehicle is stopped, the seat position control switch 21 is in the ON (seat raised) state, and the first excitation coil 25 of the first excitation switch 24 is excited. Since the switch 27 is turned ON, the second excitation coil 29 of the second excitation switch 28 is excited, and both the switch 30 and the switch 31 are in the solid line state, and the switch 31 is turned ON. , the accelerator stopper solenoid 33 and the warning lamp 34 are energized, and the accelerator stopper operation detection switch 36, which operates accordingly, is turned on and the third excitation switch 37 is activated.
becomes ON.

In this way, the power supply circuit U for raising the seat is energized, and the seat I/elevating motor 32 is moved wA by being energized in the direction of arrow A.

Due to this wjA movement, the rear sea) 5B rises.

With this rise, just before the rise limit is reached, the seat position switch 21 is turned OFF (seat is set to 1, and as a result, the first excitation coil 25 of the f51 excitation switch 24 is demagnetized, the switch 27 is turned OFF, and the remoter 32 is stopped. At this time, the second excitation switch 31 is turned off, but the switch 26 is turned on and the operation of the accelerator stopper 35 shown in FIG. 1 is maintained.

Therefore, even when the rear seat 5B is raised and reaches its upper limit, the accelerator operation is stopped.
Unable to start the vehicle.

Next, when lowering the rear sea (5B) in the above,
First, the manual switch 17 is switched to 0FF (seat lowered).

On the other hand, since the seat position switch 21 is OFF (seat raised), the first excitation coil 25 of the first excitation switch 24 is demagnetized and the switch 27 is turned OFF, so the M2 excitation coil 29 of the second excitation switch 28 is demagnetized. is also demagnetized, switches 30 and 31 are both in the broken line state,
The power supply circuit for lowering the seat is energized.

Thereby, the seat elevating motor 32 is driven by energization in the direction of arrow B, and the rear seat 5B is lowered.

In the above embodiment, the vehicle speed response switch 15 is set to turn on depending on the vehicle speed O, but when the vehicle speed is below a predetermined speed, for example, 5 to 6 km/h, which is a considerably low speed.
You can also set it to turn on below. Also, what is the above special condition?

This refers to cases in which there is no problem in driving as is, such as when the seat is reclined greatly, moved backwards as shown in Figure 1, or raised as described above. For example, this refers to the extent to which the seat can be shifted forward or backward or the backrest can be tilted up, in other words, it is safe to drive as is.

(Effect of Issue 111) As explained above, the present invention allows the seat to change to a special state only when the vehicle speed is below a predetermined speed, and when the vehicle is traveling at a speed higher than the predetermined speed, the special state is enabled. Since it is designed to prevent the vehicle from falling off, the safety of the occupants can be ensured.
