Abstract
In order to improve steering operation operability during cornering while maintaining a driver holding property, a seat apparatus is provided with: a seat back frame; a cornering sensor for detecting a cornering direction of a vehicle; and a control unit that controls the seat back frame on the basis of the result of detection by the cornering sensor. The seat back frame is provided with: left and right side frames disposed on both sides of the seat back frame; a back plate disposed between the left and right side frames; and a swinging mechanism for swinging the back plate with respect to the direction of movement of the vehicle. The control unit controls the swinging mechanism such that, upon detection of a cornering direction of the vehicle by the cornering sensor, the inner one of the sides of the back plate with respect to the cornering direction is positioned rearward of the outer one of the sides with respect to the cornering direction.

15. A seat apparatus to be mounted on a vehicle, comprising:
-
a seat cushion frame; a seat back frame which is arranged so as to stand from a back end part of the seat cushion frame; a cornering sensor which detects a cornering direction of the vehicle; a vehicle speed sensor which detects a speed of the vehicle; and a control unit which controls the seat back frame on a basis of a detection result obtained by the cornering sensor and a detection result obtained by the vehicle speed sensor, wherein the seat back frame includes; left and right side frames which are respectively arranged at two side parts of the seat back frame so as to extend in a vertical direction; and an adjustment mechanism which engages with the left and right side frames and which adjusts a posture of a driver, and wherein the control unit controls the adjustment mechanism to adjust the posture of the driver when a calculated lateral acceleration be a predetermined value or greater, the calculated lateral acceleration being calculated from the detection result obtained by the cornering sensor and the detection result obtained by the vehicle speed sensor.
