Abstract
To automatically adjust the position of a headrest accurately with a simple configuration while preventing an unnecessary movement of the headrest, a headrest position adjusting deviceincludes a capacitance sensor unitand a drive motor unit. The capacitance sensor unitincludes, for example, a plurality of sensing electrodestoand a detecting circuit. The detecting circuitincludes a plurality of capacitance sensing circuitstoconnected one-to-one to the sensing electrodesto, and an arithmetic processing circuit. The drive motor unitincludes a motor driving circuit and a drive motor. The detecting circuitjudges whether or not the smallest capacitance value among detected capacitance values is equal to or larger than a predetermined threshold, performs a position adjusting operation for a headrestwhen the smallest capacitance value is equal to or larger than the predetermined threshold, and stops the headrestor moves the headrestto a predetermined position when the smallest capacitance value is smaller than the predetermined threshold.
