VEHICLE SEAT

The vehicle seat (1) includes: an adjustment position selecting means (12, 13, 14) for selecting an adjustment position of each part of the seat (1) corresponding to the build of the occupant; a seat position adjusting means (8) for the occupant to manually adjust a position of each part of the seat (1); and a seat position detecting means for detecting a position of each part of the seat (1). Build information selected with the adjustment position selecting means and positional information detected with the seat position detecting means are transmitted to an electronic control unit (ECU) provided in the vehicle by wireless communication or wired communication. In the electronic control unit (ECU), proper positional information of each part of the seat (1) estimated based on the build information and the positional information are checked against each other. When both pieces of information agree with each other, the occupant is notified of the agreement through a notifying means.
