Abstract

PURPOSE:To make a motor-driven seat unit into a nonoperating state so quickly in case of emergency, by installing a stop signal detecting device which makes a driving device into a stopped state with an operating signal out of a brake pedal or that out of a horn during adjusting operation on the basis of operating data. CONSTITUTION:Either of position switches on a control keyboard 101 is pushed, and operating data are outputted out of an address of a corresponding memory circuit 10. Next, this operating data is compared with the existing seat position, indicating an operated variable on the basis of the difference. In consequence, a seat is adjusted before and behind and vertical directions and a drive position at each driver is reproduced. During this replaying, at the time of such emergency that a motor-driven seat unit bites clothing and fingers, a control circuit 20 is made into a nonoperating state by brake operation of a brake pedal 41, or horn operation of a horn 40 or pushing operation of a stop switch of the control keyboard 101. Since the horn and the brake pedal are at hand of the driver seated in a driver's seat, the operability is very good.

Description

[Detailed Description of the Invention] [Objective of the Invention] (Industrial Application Field) The present invention stores operation data of each part of the seat (for example, slide, lifter, reclining, etc.) for each driver in response to a preset memory operation. The present invention relates to an electric seat device which is used to store and adjust each part of the seat for each driver based on the stored operation data.

(Prior Art) Conventionally, operation data of each part of the seat for each driver is stored in a memory circuit in response to a preset memory operation, and each part of the seat is adjusted for each driver based on the operation data stored in this memory circuit. There was an electric seat device.

That is, in the electric seat device, each part of the seat (
Adjust the motors of slides and lifters. After pressing the set switch 104, the user continues to press the position switches 105-108 to be stored until the corresponding indicator lamps 109-112 light up.

At this time, the operation data of each part of the seat adjusted by the manual slide switch 102 and the manual lifter switch 103 is stored in the memory circuit for each driver (here, for four drivers) in accordance with the above-described preset storage operation.

Then, the position switches 105 to 108 are pressed and operated to adjust the motors of each part of the seat based on the operation data stored in the memory circuit. As a result, the drive position for each driver can be reproduced.

If you wish to cancel the adjustment of each part of the seat while reproducing the drive position for each driver, press stop switch 1.
When 13 is pushed, the stop signal detection circuit detects a stop signal, puts the driving means in a non-operating state, and stops the adjustment operation of each part of the seat.

(Problems to be Solved by the Invention) However, with the above-mentioned conventional electric seat device, while reproducing the drive position for each driver, clothes, etc.
In rare cases, it may bite your fingers.

In such a case, the stop switch 113 of the operation keyboard 101 is pressed to stop the adjustment operation of the electric seat device, but since the stop switch 113 is small, operability is poor in the above-mentioned emergency. The problem was that it was not possible to respond quickly. It is also possible to increase the size of the stop switch 113 in order to improve operability in an emergency, but if the operation keyboard 101 is installed near the driver, the size will be limited, and accordingly, the size of the stop switch 113 will be limited. There was also a problem in that the size of 113 was also restricted.

(Purpose of the Invention) Therefore, this invention was made by focusing on the above-mentioned conventional problems, and it outputs a stop signal using a device other than the stop switch on the operating keyboard, and uses this stop signal to reproduce the drive position for each driver. It is an object of the present invention to provide an electric seat device in which the electric seat device inside can be brought into a non-operating state.

[Structure of the Invention] (Means for Solving the Problems) The structure of the present invention for achieving the above object is to input operation data of each part of the seat for each driver into a memory circuit in response to a preset memory operation. and an electric seat device that adjusts each part of the seat by a driving means that operates each part of the seat based on operation data stored in the memory circuit,
The present invention is characterized in that it includes a stop signal detection means for bringing the drive means into a stopped state in response to a brake pedal actuation signal or a horn actuation signal during the adjustment operation based on the operation data.

(Example) The present invention will be explained below based on the drawings.

In FIG. 1, 101 is an operation keyboard. This operation keyboard 101 is similar to the conventional one shown in FIG. 3, and includes a manual slide switch 102 for manually adjusting the seat position in the front-back direction and a manual slide switch 102 for manually adjusting the seat height in the vertical direction. A manual lift switch 103 and a memory circuit 1, which will be described later, correspond to a push operation of a drive position setting switch 104 for each driver.

05 to 108 and the position switches 105 to 10
Indicator lamps 109 to 112 are turned on in response to the push operation of No. 8, and a stop switch 113 is provided to put a control circuit 20 (described later) in an inactive state during an adjustment operation based on the operation data.

10 is a memory circuit. This memory circuit 10 stores operation data manually adjusted for each driver in each address by pressing the position switches 105 to 108 after pressing the set switch 104 of the operation keyboard 101. The operation data for each driver stored in each address is output in response to the pushing operations 105 to 108.

20 is a slide motor of a motor unit 30 which will be described later;
This is a control circuit that operates a lift motor to adjust a seat (not shown). This control circuit 20 controls the motor unit 30 by a manual slide switch 102 and a manual lift switch 103 of the operation keyboard 101.
After manually operating the slide motor and lift motor of the motor unit 30 and comparing it with the current seat position based on the operation data stored in each address of the memory circuit 10, the slide motor and lift motor of the motor unit 30 are operated by the difference. It is something that makes it work.

Reference numeral 30 denotes a motor unit that includes a slide motor that moves the seat in the front-back direction and a lift motor that moves the seat in the up-down direction. Note that the control circuit 20 and the motor unit 30 are driving means for driving the seat in the longitudinal direction and the vertical direction.

Reference numeral 40 denotes a stop signal detection circuit that puts the control circuit 20 in a non-operating state during a seat adjustment operation based on the operation data for each driver stored in the memory circuit 10. This stop signal detection circuit 40 is connected to the stop switch 113 of the operation keyboard 101. Brake 41. The stop signal is detected by the activation signal of the horn 42, and is detected by the circuit shown in FIG.

That is, one end of the stop switch 113 is connected to the power supply 50 via a resistor R1, and the other end is connected to the collector of the transistor Trl via a resistor R2. A stop signal detection circuit 40 is connected between the resistor R1 and the stop switch 113. The stop switch 113 here is an automatic return type constant contact switch, and cuts off the current supply when pressed.

The transistor Tri has a base connected to a resistor R3.
It is connected to the collector of the transistor Tr2 via the transistor Tr2, and its emitter is grounded.

Further, the transistor Tr2 has a collector connected to the base of the transistor Trl and is also connected to the power supply 50 via a resistor R4, and a base connected to the brake switch 41a and the horn switch 42a in the parallel state via a resistor R5. are doing.

Furthermore, the brake switch 41a and the horn switch 42a output their activation signals as stop signals in response to the operation of the brake pedal 41 and horn 42 shown in FIG. 1, and are automatically reset type normally open switches. It is connected to the power supply 50.

Next, the operation with the electric seat system having the above configuration will be explained.

First, a case will be described in which sheet operation data is stored at an address in the memory circuit 10.

First, the manual slide switch 102 and manual lift switch 103 of the operation keyboard 101 drive the slide motor and lift motor of the motor unit 30 to adjust the seat in the longitudinal and lateral directions to determine the driver's drive position.

Next, after pressing the set switch 104, one of the position switches 105-10B is continued to be pressed until the corresponding indicator lamp 109-112 lights up.

At this time, the operation data (pulse signals) of the slide motor and lift motor of the motor unit 30 are stored in the memory circuit 20 corresponding to the position switches 105 to 108.
are stored in each address. In this embodiment, the operation data for four people can be stored in the storage circuit 20 through the operations described above.

Next, operate position switches 105 to 108,
The case of reproducing the drive position for each driver will be explained.

First, one of the position switches 105 to 108 is pressed to output operation data from the corresponding address in the memory circuit 20.

Next, this operation data is compared with the current seat position, and an operation amount based on the difference is instructed. As a result, the seat (not shown) is adjusted in the longitudinal direction and the vertical direction to reproduce the driving position for each driver.

While reproducing the drive position for each driver,
In an emergency, such as when clothing or a finger is caught in the electric seat device due to the driver's carelessness, the user must operate the brake pedal 41, operate the horn 42, or press the stop switch 113 on the operation keyboard 101. This puts the control circuit 20 into a non-operating state.

That is, the stop signal detection circuit 40 in the normal state is
As shown in Figure 2, power supply 5o → resistor R4-1 - resistor R
3 → A circuit called the base of transistor TRI is established,
The transistor Trl is turned on, and a circuit of power supply 50 -> resistor R1 -> stop switch 113 (on state) -> ground is established, and no stop signal is input.

However, when the brake or horn is operated in an emergency, the brake switch 41a or the horn switch 42a is turned on in response to the operation, and the power source 50 → the brake switch 41a or the horn switch 42a (ON state) → the resistor R5. →Transistor Tr
A circuit called the base of transistor Tr2 is established, and the transistor Tr2 is turned on to stop supplying the chisel source to the base of the transistor Tri, and the transistor Trl is turned off. As a result, the potential input to the stop signal detection circuit 40 increases. That is, when a stop signal is input, the stop signal detection circuit 40 puts the control circuit 20 into a non-operating state. Therefore, the adjustment operation of the electric seat device is stopped.

Further, even if the stop switch 113 is pressed, a stop signal is input to the stop signal detection circuit 40 in the same manner as described above, and the control circuit 20 is put into a non-operating state.

[Effects of the Invention] As explained above, according to the present invention, the operation data of each part of the seat for each driver is input into the memory circuit in response to the preset memory operation, and the operation data stored in the memory circuit is inputted into the memory circuit. A driving means that operates each part of the seat based on the
In the electric seat device that adjusts each part of the seat for each driver, the driving means is in the adjustment operation based on the operation data.

Since the horn and brake pedal are installed near the driver who is seated in the driver's seat, the horn and brake pedal are installed near the driver who is seated in the driver's seat, so the horn and brake pedal are installed near the driver who is seated in the driver's seat. The performance is very good, and the horn and brake pedal can be operated quickly even in the event of an emergency, such as when the electric seat device gets caught in clothing or fingers. Therefore, an excellent effect can be obtained in that the electric seat device can be quickly put into a non-operating state in an emergency.
