Document Type and Number:
Japanese Patent JP6876284
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a seat device capable of acquiring distribution of a load applied to a support surface with further high accuracy.SOLUTION: The seat device includes: a cushion material 11 (a load support body) having a support surface 11A for supporting a load of a sitter; and a load distribution detector 12 for detecting distribution of a load applied to the support surface 11A. The load distribution detector 12 includes: a woven fabric 13 (a cover body) for covering the support surface 11A; a pressure sensitive cell 13J that is formed at a part of the woven fabric 13, for covering the support surface 11A, and whose electrostatic capacity is varied in response to a load received; a reference cell 13L conducting the pressure sensitive cell 13J: and correction means performing correction of variation in the electrostatic capacity of the pressure sensitive cell 13J by suppressing a crosstalk signal in the reference cell 13L.SELECTED DRAWING: Figure 2
