Description

[Detailed Description of the Invention] <<Technical Field of the Invention>> The present invention relates to a vehicle seat control device that allows multi-item control of the seat, and particularly relates to an improvement of an operating section such as a mode changeover switch in the seat control device.

《Prior art and its problems》 Vehicle seat control devices use motors to adjust the height of the seat, the front and rear positions of the seat, etc., or are built into various parts of the seat as shown in Japanese Patent Laid-Open Publication No. 58-53524. The internal pressure of the air bag is adjusted by controlling the air pump, etc. to adjust the shape of the support part.
This allows passengers to move to the optimal seat position and seat shape according to their seating posture.

Incidentally, heretofore, switches corresponding to the displacement modes provided in this type of device have been provided at appropriate intervals on the side of the seat, and the switch has to be operated by groping for each switch. For this reason, each switch not only protrudes from the side of the seat and spoils the appearance of the seat, but also makes it extremely difficult to operate the switches.

[Purpose of the invention] The present invention was created in view of the above circumstances, and aims to provide a seat control device that is the easiest to operate without the operation section and display section of the seat control device getting in the way of the occupant. purpose.

<<Structure of the invention>> In order to achieve the above object, the present invention includes a mode selection switch that cyclically switches the control mode of the position of the vehicle seat or the shape of the support part, and a control mode that corresponds to the switching operation of the mode selection switch. an increase/decrease switch for changing the position of the seat or the shape of the support part, and an input signal from the increase/decrease switch to change the position of the seat or the shape of the support part in a mode corresponding to the switching operation of the mode selection switch. The seat control device is equipped with a control unit for controlling the amount of displacement of the mode changeover switch, the display unit, and the increase/decrease switch, the mode changeover switch, the display unit, and the increase/decrease switch being arranged on one panel, and the panel being attached to the side part of the seat cushion of the seat. It is characterized by being worn.

<<Description of Embodiments>> FIG. 1 is a control block diagram of the vehicle seat control device of the present invention.

The control device in the figure includes a mode selection switch MSW that cyclically switches the control mode for the seat position or the shape of the support part, a mode switching means 1 that cyclically switches the control mode by switching the mode selection switch MSW, and a control mode. a display display 2 for displaying the control mode, an audio display section 3 for audibly displaying the control mode, a pair of increase/decrease switches 4a, 4b for displacing the seat position or the shape of the support part, and a pair of increase/decrease switches 4a, 4b for controlling the seat position. The control section 5 controls the position or the amount of displacement of the shape of the support section.

The display 2 is configured as a display using a liquid crystal plate or the like. This display 2 shows the corresponding position of the seat map illustrated by the switching operation of the mode selection switch MSW.
Depending on the control mode, it suggests a message of the shape of the support part, such as "up and down of the seat", "front and back of the seat", "reclining" position, or "side", "thigh", "lumbar", etc. That is, by repeatedly operating the mode selection switch MSW, the message of each control mode is sent to the instruction section 2.
are displayed in sequence.

Further, the control mode from the mode switching means 1 is supplied to the audio display section 3. The audio display section 3 includes an audio switching means 3a that outputs a built-in audio warning signal for each control mode according to the switching mode from the mode switching means 1, and outputs the output signal from the speaker 3b as audio.

By providing the audio display section 3, the control mode can be selected by hearing without visually checking the display section, and safety during driving can be ensured.

Further, the control section 5 is composed of a drive section switching means 6 and a forward/reverse switching means 7.

The forward/reverse switching means 7 includes solenoids S1, S2, S.
3 and motors M1, M2, and M3 are connected. Solenoids S1, S2, S3 are air pump P
This opens and closes the air from the airbag, which opens and closes the intake and exhaust valves of the airbags built into the thigh support, side support, and lumbar support.

Further, the motors M1, M2, and M3 are used to adjust the seat position up and down, adjust the seat position back and forth, and reversibly adjust the reclining angle.

The forward/reverse switching means 7 is connected to each of the solenoids S1 and S.
2, S3 and a drive circuit such as a relay for individually driving the motors M1, M2, and M3 in forward and reverse directions.

Further, the drive section switching means individually connects each drive circuit built in the increase/decrease switches 4a, 4b and the forward/reverse switching means 7 in accordance with the control mode supplied from the mode switching means 1.

Therefore, the position of increase/decrease switch 4 corresponds to the control mode selected by mode selection switch MSW.
Variable control can be performed depending on the forward/reverse direction of a and 4b and the amount of operation.

Furthermore, the mode changeover switch MSW, the display 2, and the increase/decrease switches 4a and 4b are arranged on one panel 8 at appropriate intervals, as shown in FIG. It is attached to the upper surface of the side part of the seat cushion 10 of the seat 9.

3 and 4 show the seat mounting structure of the panel 8.

The seat cushion 10 has a structure in which an internal pad 10a is covered with a trim cover 10b. Further, on the inside of the seat cushion 10, an L-shaped bracket 9 connects the lower end 9a to the seat frame 1.
0c with screws 11. The panel 8 is placed on the upper surface of the bracket 9 via a trim cover 10b, and a resin cover 12 having a notch 12a is arranged so as to press down the panel 8. and panel 8
The cover 12 and the cover 12 are each fixed to the bracket 9 by screws 13 and form a part of the seat cushion 10.

By mounting the mode changeover switch MSW, the display 2, and the increase/decrease switches 4a and 4b on the seat cushion 10 in this manner, they do not get in the way even when a passenger is seated, and are easy to operate.

In the above embodiment, the audio switching means 3 was provided together with the display 2, but in the control device of the present invention, the audio switching means 3 or the display 2 is provided.
The control device may be configured using one of the two.

<<Effect of the invention>> As explained above, according to the vehicle seat control device of the present invention, the operation section and the display of the seat control device are arranged on one panel, and this panel is arranged on the side part of the seat cushion. Since the device is mounted on the top surface of the vehicle, the operating section and the display do not get in the way of the passenger, and the display can be seen and operated easily even when the passenger is seated on the seat.
