Attitude control system for driver's seat

Attitude control system for driver's seat comprising:

• seat attitude setting means;
• driving means adapted to drive the seat attitude setting means;
• signal generator means coupled to the seat attitude setting means for generating an electric pulse for each movement of the seat attitude setting means;
• a plurality of key switches;
• a character display;
• and
• an electronic control device comprising electronic processor means and memory means including a read only memory, a read-write memory and a non-volatile, read-write memory, said memory means storing standard attitude data corresponding to human data indicative of the physical features of a driver,
• said electronic control device being capable of reading standard attitude data which corresponds to the human data inputted with the key switches from the memory means and controlling the energization of the driving means for establishing an attitude indicated by the read-out standard attitude data with reference to actual attitude data based on the counting of electric pulses,
• said electronic control device storing acutal attitude data at a predetermined address of the non-volatile, read-write memory when an identification code and a memory instruction are inputted by the key switches, said address corresponds to the identification code inputted,
• said electronic control device being responsive to input of an identification code and a set instruction with the key switches, reading the attitude data at the address which corresponds to the inputted identification code, controlling the energization of the driving means for establishing an attitude indicated by the attitude data corresponding to the inputted identification code with reference to the actual attitude data based on the counting of the electric pulses, and
• said electronic control device, during the energization of the driving means, forming the actual attitude data by counting up or down the electric pulses depending on the drive direction of the seat attitude setting means and storing the actual attitude data in the non-volatile, read-write memory as the current attitude data after it stops the energization of the driving means.
