Seat apparatus for vehicle

U.S. Patent Number: 5320409

Abstract: A seat apparatus for a vehicle includes a seat which is composed of a seat cushion and a seat back. A plurality of actuators are provided in the seat, for altering a bearing-surface configuration of the seat. The actuators are driven by an air compressor which is controlled by a controller in a predetermined pattern. The controller judges oscillation transmitted to a passenger seated on the seat, on the basis of a signal from an acceleration sensor, and regulates the predetermined pattern of the control, in accordance with the judged oscillation. The controller may be so arranged as to judge the oscillation transmitted to the passenger, on the basis of signals from a speed sensor and a road-surface-condition detecting sensor.
