Abstract

PURPOSE: To recognize the operation and completion of an adjusted section at the time of memory adjustment by indicating the adjusted section during the memory adjustment and issuing an alarm after the completion of the memory adjustment when performing the longitudinal position adjustment or the like of a head rest through motor driving. CONSTITUTION: The longitudinal position adjustment of a head rest 1, the reclination angle adjustment of a seat back 2 and the longitudinal position adjustment of an ottoman 4 or the like are performed through motor driving. In that case, at the time of memory adjustment, the operation of the adjusted section is recognized by operating lamps 36-41 provided corresponding to the moving directions of adjusted sections and the completion of memory adjustment is recognized by an alarm tone sounded by an alarm. As a result, the operation and completion of the adjusted section can be recognized at the time of memory adjustment.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a seat in which the longitudinal position adjustment of a headrest, the inclination angle adjustment of a seat back, the longitudinal position adjustment of an ottoman, etc. are performed by driving a motor.

(Conventional technology) As a conventional technique, there is a sheet shown in FIG.

In the figure, 1 is a headrest, 2 is a seat back, 3 is a seat cushion, and 4 is an Ottoman.

Then, the headrest 1 is adjusted fore and aft in the front-rear direction (direction of the arrow ■) relative to the seatback 2, the inclination angle adjustment is performed such that the seatback 2 is tilted a (direction of the arrow ■) relative to the seat cushion 3, and It is possible to adjust the position of the seat cushion 3 by moving it forward and backward (in the direction of the arrow ■), and these adjustments are made by driving a motor (not shown).

(Problem to be solved by the invention) In the seat with the above configuration, the seat position is set to R in advance.
The headrest 1. is stored in AM etc. and moved to the stored seat position with one touch. seat back 2
．． There is a device that performs so-called memory adjustment to operate the automan 4.

However, in the case of a seat with many adjustment parts, when adjusting the memory, the adjustment parts and non-adjustment parts coexist, and the user cannot recognize whether each part is being adjusted or whether the adjustment is complete. There is a problem.

The present invention has been made in view of the above-mentioned problems, and an object thereof is to realize a seat that can recognize when the adjustment part is in operation and when the adjustment part is completed when adjusting the memory.

(Means for Solving the Problems) The present invention, which solves the above-mentioned problems, provides a memory adjustment method for a seat in which the front and back position adjustment of the headrest, the tilt angle adjustment of the seat back, the front and back position adjustment of the ottoman, etc. are performed by motor drive. Inside, the adjustment part is displayed, and an alarm is issued when the memory adjustment is completed.

(Function) In the seat of the present invention, the adjustment portion is displayed during adjustment, and an alarm is issued when adjustment is completed.

(Example) Next, an example of the present invention will be described using FIGS. 1 to 3. FIG. 1 is a flowchart of this embodiment, FIG. 2 is a circuit diagram in FIG. 1, and FIG. 3 is a diagram showing the controller in FIG. 1. It should be noted that the seat in this embodiment is a seat in which the front and back positions of the headrest, the inclination angle of the seat back, and the back and forth positions of the ottoman can be adjusted, as in the conventional example shown in FIG. , 4th
The names and numbers used in the figures are used as they are.

First, in FIG. 2, 11 is a CPLI that takes in data and performs various operations, 12 is a ROM in which a program for executing CPLJll is written, and 14 is a RAM in which data such as seat position is written. be. 15 is a headrest movement motor that moves the headrest 1 in the direction of the arrow ■; 16 is a driver that drives the headrest movement [-15]; 17 is a potentiometer that outputs the displacement of the headrest 1; and 18 is an analog signal of the potentiometer 17. This is an A/D converter that converts into digital signals. 19 is a seatback tilting motor that tilts the seatback 2 in the direction of the arrow ■; 20 is a driver that drives the seatback tilting motor 19; 21 is a potentiometer that detects the displacement of the seatback 2; 22 is an analog signal of the potentiometer 21. This is an A/D converter that converts the signal into a digital signal. 23 points to the ottoman 4■
24 is a driver that drives the Ottoman moving motor 23; 25 is a potentiometer that detects the displacement of the Ottoman 4; 26
is an A/D converter that converts the analog signal of the potentiometer 25 into a digital signal.

Next, in FIGS. 2 and 3, 27 to 29 are memory switches, and 30 to 35 are manual switches provided to operate the headrest 1, seat back 2, and Ottoman 4 in both directions.

An operating lamp 36 is located inside these manual switches 30 to 35.
-41 are provided, and when manual switches 30-35 are pressed, operation lamps 36-41 light up to indicate what is being operated and in which direction. Reference numeral 42 denotes an operation lamp that lights up while at least one of the headrest 1, the seat back 2, and the seatback 4 is in operation. 43 is the desired seat position (setting position Iff)
Memory set button used when storing data in AM14,
44 is an alarm, and 45 is an emergency stop switch.

Memory switches 27-29, manual switches 30-3
5, operating lamps 36 to 42, memory set button 43,
The alarm 44 and the emergency stop switch 45 are connected to the CPU 11 via an interface circuit 46 .

Next, the operation of the above configuration will be explained using FIG. 1. First, an initial setting is performed in which desired setting positions (three in this embodiment) are stored in the RAM 14 using the memory set button 43 (step 1). Next, manual switch 30~
35 is turned on (step 2). If manual switches 30-35 are not turned on, then
Check whether memory switches 27 to 29 are turned on (step 4). If it is not turned on, return to step 1 and continue monitoring. If it is on, memory adjustment is performed and it is checked whether the current seat position is at the memory setting position (step 5). If it is not at the set position, the corresponding motor of the corresponding part is operated (step 6). and,
The corresponding lamp among the operating runs 36 to 41 is turned on, and the operating lamp 42 is also turned on (step 7).

Next, it is determined whether the emergency stop switch 45 has been turned on (step 8). If it is not turned on, step 5
Return to If it is turned on, stop all motors (step 9) and turn off the operating lamps 36 to 42 in step 1.

Step 11), return to step 2. Further, if it is determined in step 5 that the set position is reached, the process moves to step 9.

In step 2, if any one of the manual switches 30 to 35 is turned on, manual adjustment is performed.
The corresponding motor is activated (step 12). Then, the corresponding lamp among the operating lamps 36 to 41 is turned on, and the operating lamp 42 is also turned on (step 13).
, return to step 2.

According to the above configuration, when adjusting the memory, the operation of the adjustment parts is controlled by the operation lamps 36 to 36 provided corresponding to the moving direction of each part.
41, and completion can be signaled by an alarm sound emitted by the alarm device 44.

Note that the present invention is not limited to the above embodiments.
