Abstract

PURPOSE: To automatically set a headrest to an optimum position by providing a head detecting means by which whether or not the head part of an occupant sitting on a seat is detected in correspondence to the headrest, by driving the headrest while monitoring the detecting information of the head detecting means, and by positioning the headrest making a reference of the position where the detecting information is changed. CONSTITUTION: The threshold value is a set value actually measured of the oscillating frequency of an OSC when an occupant sits down on a seat and the headrest is elevatedly driven, and the flag is set as the head top has been detected, when the value of a resistor RC or the increment of frequency data for 0.1 second exceeds this threshold value. When the flag is set by detecting the head top part while elevatedly driving the headrest for monitoring the flag, a timer is cleared and started for directing the de-enerizing of a relay RL1 and the energizing of a relay RL2 to a relay driver 2, so that the motor is reversely energized. Thus, the headrest is lowered as much as a prescribed value from the position for detecting the head top part, and is finely adjusted to an optimum position.
