Power seat apparatus

A power seat apparatus comprising:

• a slide-motor for sliding a seat in a front or rear direction;
• a lift-motor for driving the seat up or down;
• a recliner-motor for adjusting a reclining angle of a seat back of the seat;
• a preset memory means for storing operating data of said respective motors in response to a preset operation;
• a memory drive means for driving said motors according to the operating data stored in said preset memory means;
• a manual drive means for driving said motors according to an operation of a manual switch means;
• a relay for changing a direction of electric current to be supplied for said respective motors;
• and
• a control means for stopping said motors by dynamic braking if the manual switch means is operated so as to rotate the motors in one direction while said motors are driven automatically in the opposite direction by said memory drive means, for counting the operating data output from said respective motors during inertial rotations of the motors as signals in the opposite direction in which said motors have been driven automatically by said memory drive means, and for driving said motors through the manual drive means in said one direction according to the operation of said manual switch means, said control means further giving a warning through a warning means and controlling the motors upon detection of a contact fault in said relay.
