A signal is sent to detect that a passenger is sitting in the seat.

FIG. 4 shows another embodiment of the present invention, in which the light emitter 3 and the light receiver 4 are placed on both sides of the seat 1 (armless) 7a,
An example is shown in which they are provided facing each other inside 7b. Note that the light emitter 3 and the light receiver 4 may be mounted anywhere other than the armrest as long as they are located on both sides of the seat, such as a door.

As described above, according to the present invention, it is possible to remotely know whether or not a passenger has occupied the seat 1, and the passenger seating detection device according to the present invention can be used in the following devices. can.

i11 Seatbelt fastening detection device When there are many seats, such as in an aircraft, this system detects whether a person is actually seated by combining the signal from the seatbelt fastening switch, which turns on when the seatbelt is fastened, with the seating signal. It is possible to remotely determine whether each passenger is wearing their seat belt.

In other words, as shown in FIG. ~lln, respectively, from the first to nth AND circuits 12. ~12n, each AND circuit 12
1 to 12n are connected to the ND circuit 13.

In the above configuration, only when the passenger is seated and fastens the seat belt, the ANDII of the seat is
Signal 11 from D path 12t~12n or NAND Sono v! 1
3 is output. If a passenger is seated but does not wear a seat belt, an IO signal is output from the AND circuit of the seat to the NANDb path 13. And all ANDIa paths 12. When all the signals from ~12n reach 11, the output signal from the NAND circuit 13 becomes '0', indicating that all the passengers seated in the seats have fastened their seat belts.

In this way, it is possible to easily and accurately determine whether all occupants of a vehicle, aircraft, etc. are fastening their seat belts.

(2) Control Lever for Construction Machinery In construction machinery such as bulldozers, it is extremely dangerous if the control lever 1d becomes restricted when the passenger is not properly seated in the driver's seat. Therefore, by combining the passenger seating detection device and the control lever operating system according to the present invention, the control lever can be locked when no passenger is on board, thereby preventing malfunction of the control lever.

FIG. 6 shows an example of this, in which an electromagnetic switching valve 22 is interposed in the circuit between the work machine cylinder 20 and the control valve 2 that controls it, and the solenoid 23 of the electromagnetic switching valve 22 is connected to the main circuit. It is connected to the output section 24 of the passenger seating detection device according to the invention.

When a signal indicating that the passenger is seated is input from the passenger seating detection device to the solenoid 23, the t8 switching valve 22 becomes connected, and in this state, the work machine cylinder 20 is operated by the control valve 21. becomes controllable.

FIG. 7 shows another example, in which the control valve 21 is operated by an actuator 25, and this actuator 25 is operated by a controller 26 controlled by an electric signal controlled by a lever or the like. It's about to be controlled. This controller 26 is turned on by a signal from the signal transmitter 24 of the passenger seating detection device according to the present invention.
, is turned OFF, and is turned ON when a seating signal from the passenger seating detection device 1 is received, allowing a series of controls to be performed.

In this way, the Toki with the passenger seated in the seat operates the work machine cylinder and transmission clutch according to the operation of the work machine and transmission lever. Despite operating the machine lever and transmission lever, the work machine cylinder etc. did not operate.

It is possible to prevent malfunction of the lever in the absence of a passenger, thereby increasing safety. '+31 Vehicle Parking Brake In vehicles such as dump trucks and wheel loaders, the parking brake must be operated when no passengers are on board, but this parking brake is often not operated due to forgetfulness. That's it. Therefore, by combining the occupant seating detection device according to the present invention with the parking brake operating system, it is possible to automatically operate the parking brake when no passenger is on board.

FIG. S shows an embodiment thereof. The parking brake 30 shown in this example is released by air pressure and operated by spring force, and a tfB switching valve 31 is installed in the air circuit. The output part 1 of the passenger seating detection device signal transmitter 33 according to the present invention is connected to the solenoid 32 of the solenoid 32 .

However, when a seating signal from the passenger seating detection device is input, the signal becomes 1! ! The magnetic cut-off valve 31 is in the release position, and when the seating signal is turned off, it is in the actuation position, and the parking brake 1 is actuated.

In this way, the parking brake is released when the passenger is seated in the seat, and the parking brake is automatically activated when the passenger stands up or leaves the seat, thereby preventing forgetting to apply the parking brake. , it is possible to dramatically improve vehicle safety.
