Patent number: 8678502Abstract: A headrest position adjustment device includes a capacitance sensor unit, and a drive motor unit. The capacitance sensor unit includes a plurality of electrode groups each configured by a plurality of sensing electrodes. The total electrode area of each of the electrode groups is switchable by a switching unit of a circuit unit between at least a total electrode area A and a total electrode area A+B. The total electrode area A is selected when the distance d between a head and a headrest is short, and the total electrode area A+B is selected when the distance is long. In this way, the sensitivity is changed depending on how long or how short the distance is. An estimated center position of the head is calculated based on capacitance values obtained, and thereby the position of the headrest is adjusted.Type: GrantFiled: October 18, 2010Date of Patent: March 25, 2014Assignee: Fujikura Ltd.Inventors: Takuya Osaki, Yuichiro Yamaguchi, Yuki Noguchi, Koji Sakiyama
