ABSTRACT:
A method and device for controlling a motor in a powered seat, wherein, in an automatic control mode, a rated voltage is applied to the motor, thereby causing a constant high rotation of the motor, and in a manual control mode, firstly the rated voltage is applied to the motor and secondly after a given time, the voltage is changed into a low voltage, causing the motor to be driven at a low rotation rate. Thus, the movable parts of seating posture adjustment device in the seat are moved rapidly in the automatic mode, while in the manual mode, they are firstly moved rapidly and then slowly for permitting an accurate adjustment of position thereof.
