US Patent No: 9975452

Seat having capacitive coupling sensor

---

Abstract

---

A seat configured so that the accuracy of detection of each sensor provided in the seat to detect the body potential of a seated occupant can be improved without degrading the sense and comfort of the seat. A seat includes a trim cover having a contact surface for a seated occupant, and sensors arranged opposite to the contact surface and configured to detect the body potential of the seated occupant. Each sensor is a capacitive coupling sensor configured to detect the body potential through the trim cover. Moreover, a portion of the seat facing each sensor includes a dielectric configured to increase the dielectric constant of such a portion.
