  "textContent": "To automatically adjust a position of a headrest accurately by preventing an unnecessary movement of the headrest, a headrest position adjusting device includes a sensing electrode 1 and a detecting circuit 2 embedded in a headrest 13 provided on a seat 10, an arithmetic circuit 5, a headrest driving motor 3, and a motor control circuit 4. The arithmetic circuit 5 calculates the distance between the head 22 of an occupant 21 and the headrest 13 and an amount of change of a capacitance based on a capacitance value from the detecting circuit 2. The motor control circuit 4 controls the headrest driving motor 3 in accordance with the calculation results to adjust the position of the headrest 13. When a vehicle signal from a vehicle signal output unit 6 is a specific signal or when the amount of change of the capacitance per a predetermined time is larger than a certain threshold, the arithmetic circuit 5 outputs to the motor control circuit 4 a calculation result for suspending the position adjusting operation for the headrest 13.",
