Abstract: 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.

Abstract: 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.

Abstract: A seat apparatus includes a seat cushion on which an operator is seated, a seatback supporting the operator seated on the seat cushion, the seatback being configured to incline forward to reduce an angle of the seatback relative to the seat cushion and to incline rearward to increase the angle of the seatback relative to the seat cushion, a seatback drive device inclining the seatback forward and rearward relative to the seat cushion, a seatback operating switch provided at a position where is reached by the operator seated on the seat cushion, the seatback operating switch operating the seatback driving device in response to an operation of the switch, and an excessive load restricting device restricting an excessive load applied to the operator seated on the seat cushion by limiting a forward inclination of the seatback when the seatback operating switch is operated so as to incline the seatback forward.

Abstract: 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.

Abstract: A seating detector comprises a plurality of load sensors provided at a seat for detecting partial loads applied to the seat, a total load calculating means for calculating a total load by summing up the partial loads detected by the load sensors, an occupant determining means for determining an occupant of the seat based on an comparison between the total load calculated by the total load calculating means and at least one of thresholds, a detecting means for detecting fastened/unfastened conditions of the seat belt, a judging means for judging whether or not the total load is in a predetermined range when it is detected by the detecting means that the unfastened condition of the seat belt is switched to the fastened condition, a determination maintaining means for maintaining a determination of the occupant of the seat as a child restraint system when it is judged that the total load is in the predetermined range.

Abstract: 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.
