ABSTRACT:
Method and device for controlling a slide motion of a vehicle seat, wherein when the seat is moved from a seating position to a backward position, the rotation number of a motor causing such movement is counted up from zero and memorized by a counter, so that the seat is returnable to the seating position precisely in accordance as the counter counts down that memorized rotation number to zero. This control is effected by switch means electrically arranged with the motor via electric circuits, and the counter is reset to zero every time of initial operation of the switch means, thus allowing free setting by different occupant of the seat positions without need for hitherto inputting works inherent in computer control.
