Since this device has the above-mentioned functions, it has the following effects.

First, all the next operating instructions and current operating status are displayed on the CR7 screen, allowing for interactive operation.
There is no need to check the operating instructions in the instruction manual each time, making it easier to operate.

Second, as a key to operate each part of the seat,
Since numeric keys are shared in addition to the four function keys, all parts and all directions can be specified with a small number of keys despite the large number of operating parts and the number of operating directions. Therefore, the keyboard could be downsized.

Thirdly, when in manual mode, the operating direction is displayed on the CR7 screen, and the arrow keys indicating the operating direction on the keyboard are illuminated, eliminating mistakes in operating direction and improving operability.

Fourthly, we display the shapes of each part of the sheet on the CRT screen, and only the parts that move are made to flash. Confirmation has become easier.

Fifth, we have added new modes that were not available before, such as relax mode, tight fit mode, full flat mode, and even reflex nosh mode, so we can provide a vehicle seat that is safe and does not cause fatigue even when riding for long periods of time. Ta.

Effects of the Invention As is clear from the above explanation, according to the present invention, key operation instructions and sheet operation parts are specifically displayed on the CRT display in each mode.
By interacting with the T-display and operating the keys as instructed, desired adjustments can be made, making it easy to use even for beginners.
