A seat apparatus includes a seat back capable of being used as a table at a surface thereof, a seat back driving device moving the seat back between a seating position and a table position, a controlling portion controlling the seat back driving device, and the controlling portion including an operating portion at which the user executes a certain operation, wherein, when the user executes the certain operation, the controlling portion controls the seat back to move in a first direction that is opposite to a second direction to which the seat back is moved most recently.

Seat apparatus

A seat apparatus includes a seat cushion on which an operator is seated, a seatback for supporting the operator seated on the seat cushion, a seat drive device changing a position of the seat cushion and the seatback between a seating position and a storage position by operating the seat cushion and the seatback, and a control unit for controlling the seat drive device, the control unit controlling the seat drive device in a way that an operation starting time of the seat cushion does not coincide with an operation starting time of the seatback and an operating time of the seat cushion overlaps temporally an operating time of the seatback when the seat cushion and the seatback are moved between the seating position and the storage position such that an interference of the seat cushion and the seatback is restricted.

An occupant weight detecting device includes plural cells provided on a seat and detecting pressure which is defined by rows in a width direction of the seat and columns in a back-and-forth direction of the seat, a peak row detecting means for calculating the sum of pressure per cells of predetermined number of rows adjoining in the back-and-forth direction and detecting any one row of the predetermined number of rows corresponding to the maximum sum to be defined as a peak row, and a detecting means for detecting a concentrated load position on the seat based on the peak row.

A disturbance compensation control system which restricts periodic disturbance of a control object such as a motor includes a repetition control unit. The repetition control unit restricts the periodic disturbance to the control object. The repetition control unit is designed so as not to perform a repetition compensation control when the control object is initially started.
