First, when the occupant repeatedly presses the mode select switch 13, the output sections 209b to 20 of the counter circuit 209
The ``1'' level part output to 9n is switched cyclically to ζ.For example, when the output part 209b is at the ``l'' level, the condition for both players of game 1-G7 to become 1'' is satisfied. The output of the AND gate G7 oscillates in synchronization with the timing at which the oscillation output of the second oscillation circuit 208 becomes "1". This oscillation output is connected to the diode D6. D7 and exclusive OR circuit G2. The segments 52 and 53 are driven through G3, and as a result, each of the segments 52 and 53 flashes.

In the above state, when one of the increase/decrease switches 11 and 12, for example the decrease switch 11, is pressed, the delay circuit 20
4, the cathode side of the diode D1 goes to the "0" level, and as a result, the segment 52 becomes "off" and only the segment 53 becomes a blinking display, indicating the attitude control direction.

At this time, the voice synthesis circuit 210 also uses the delay circuit 204.
For example, a notification sound such as "Ushirohou Kouniido Uchuudesu." is synthesized by the input from.

At the same time, the input from the output section 209b of the counter circuit 209 and the input from the delay circuit 204 result in an output force of 1'' from the ant gate G1o, and the motor actuator for sliding the seat position backward is activated via the circuit 31. Driven.

Further, even when another posture control mode is selected, the seat control is performed in the same manner as described above, and the control mode and control direction are displayed on each display means.

Note that the display means is not limited to the embodiments as long as it can notify the occupant of the attitude control mode and control direction.

Therefore, an audiovisual device such as a CRT display may be used to display images in a multiplexed manner along with other navigator displays, vehicle information displays, warning displays, etc.

Effects of the Present Invention As explained in detail above, the present invention is characterized in that the mode selection circuit is equipped with means for deriving a signal indicating the attitude control direction to the display means by operating the increase/decrease switch. .

Therefore, operation is simplified with fewer operation switches,
In addition, there are excellent effects such as the ability to clearly display the attitude control direction using the display means.

In addition, a wide variety of display means can be selected and used, such as a means for recognizing through the auditory sense using a speech synthesizer, etc., a means for multiplexing display with other displays using an audiovisual device, etc. This has the effect of providing a highly flexible display.
