ABSTRACT:
A power seat apparatus which comprises motors for moving a seat in respective direction, relays for changing rotational directions of the respective motors, a preset memory for memorizing a seat position suitable for respective drivers, a memory drive circuit for driving the motors so as to move the seat into the memorized position automatically according to data memorized in the preset memory, a manual drive circuit for driving the motors according to an operation of a manual switch and a control mechanism. The control mechanism detects the contact fault in the relays, or controls the motors accurately by counting the number of inertial rotations as a proper directional rotation without misjudgement even if the manual switch is operated in the reverse direction when the motors are driven automatically in one direction.
