To provide a shoulder blade position estimation device and the like which properly estimate positions of shoulder blades of an occupant.SOLUTION: There is provided a shoulder blade position estimation device which is provided on a seat 1 on which an occupant 100 who operates a steering wheel SW of a vehicle is seated, and estimates positions of shoulder blades 132 of the occupant. The seat comprises: a seat surface part 10 on which a thigh part 120 and a lumbar part 110 of the occupant are placed; and a seat back 20 which is arranged on the rear side of an upper body 130 of the occupant. The shoulder blade position estimation device comprises: a surface pressure sensor 40 which detects the surface pressure distribution received by the seat back from the upper body of the occupant; and a shoulder blade position estimation unit 90 which estimates that the shoulder blades exist in the vicinity of a region where the surface pressures detected by the surface pressure sensor change in the horizontally reverse directions when the occupant rotates the steering wheel at a prescribed angle.SELECTED DRAWING: Figure 5
【課題】乗員の肩甲骨の位置を適切に推定可能な肩甲骨位置推定装置等を提供する。【解決手段】車両のステアリングホイールSWを操作する乗員100が着座するシート1に設けられ乗員の肩甲骨132の位置を推定する肩甲骨位置推定装置を、シートは、乗員の大腿部120及び腰部110が載せられる座面部10と、乗員の上体130後方に配置されるシートバック20とを備え、肩甲骨位置推定装置は、乗員の上体からシートバックが受ける面圧分布を検出する面圧センサ40と、乗員がステアリングホイールを所定角度回動させた際に、面圧センサが検出した面圧が左右で逆方向に変化した領域の近傍に肩甲骨が存在すると推定する肩甲骨位置推定部90とを備える構成とする。【選択図】図5
