A head rest position adjusting device 100 has a capacitance sensor unit 10 and a drive motor unit 30, and the capacitance sensor unit 10 has plural detection electrodes 11 to 15. Each detection electrode 11 to 15 are formed in a rectangular strip having a long side arranged in a width direction intersecting with a height direction of a head restraint 43 at the front face side thereof, and are arranged in such a way that the long sides are aligned along the height direction. A detection circuit 20 has plural capacitance detection circuits 21 to 25 connected to the detection electrodes 11 to 15, respectively, and an arithmetic processing circuit 28, and the drive motor unit 30 has a motor drive circuit and a drive motor. Even if the head restraint 43 is in an initial condition, the detection circuit 20 detects an estimated center position of a head 49 in the height direction or a detection electrode having the highest output as a reference position from detection signals from individual detection electrodes 11 to 15, and adjusts a position of the head restraint 43 relative to a seat 40 with reference to the reference position.

A headrest position adjusting device 100 includes a distance measuring device 10 and a drive motor unit 30. The distance measuring device 10 includes a plurality of sensing electrodes 11 to 15 and a detecting circuit 20. The detecting circuit 20 includes a plurality of capacitance sensing circuits 21 to 25 connected one-to-one to the sensing electrodes 11 to 15, and an arithmetic processing circuit 28. The drive motor unit 30 includes a motor driving circuit and a drive motor. Based on the detected capacitance values, the detecting circuit 20 calculates a difference value between a capacitance value of the sensing electrode which shows the largest capacitance value and the capacitance value of the sensing electrode which shows the lowest capacitance value, and thereby measures an electrode-head distance L. A position adjusting operation for a headrest 43 is performed based on the measurement result.

摘要:
To perform highly precise position adjustment for head restraint in short time regardless of distance between head restraint and human body and head shape. Head restraint position adjusting device 100 includes capacitance sensor unit 10 and drive motor unit 30. Capacitance sensor unit 10 includes first and third sensing electrodes 11 and 13 and detection circuit 20. First sensing electrode 11 is arranged in an upper portion of front portion of head restraint 43 and senses capacitance between itself and vicinity of parietal region 49a of head 49 of human body 48. Third sensing electrode 13 is arranged in lower portion of front portion and senses capacitance between itself and any portion of human body 48 other than vicinity of parietal region 49a. When head restraint 43 moves from initial condition, detection circuit 20 detects position of parietal region 49a of head 49 (parietal region position) and determines appropriate position of head restraint 43 for head 49, enabling highly precise position adjustment in short time.
