Claims

[Claims for Utility Model Registration] 1. The seat cushion main frame has an ischium support plate extending in the width direction approximately at the center in the front and back direction, and a cushion pad is provided between this plate and the seat cushion skin. A cushion pad is provided between the seat cushion and the seat back main frame. A cushion air chamber disposed between the above-mentioned Ischiam support plate and the cushion pad; A back air chamber disposed between the pad and the pad, an air supply means for supplying air pressure to each of the above air chambers, and an air supply means that supplies air pressure to each of the above air chambers simultaneously or sequentially over time. A seat structure characterized by comprising a controller for changing the seat structure. 2. A seat cushion that has an ischia support plate that extends in the width direction at approximately the center in the front-rear direction of the seat cushion main frame, and a cushion pad is interposed between this plate and the seat cushion skin. , a seat back having a solar support plate extending in the width direction at approximately the center in the vertical direction of the seat back main frame, and a cushion pad interposed between this plate and the seat back skin. In a seat structure consisting of a cushion air chamber disposed between the above-mentioned Ischiam support plate and the cushion pad, and a cushion air chamber disposed between the above-mentioned solar support plate and the cushion pad. A back air chamber, and a seat cushion that is disposed between adjacent members of any one of the plate, air chamber, pad, and skin of the seat cushion and detects the pressure applied to the seat cushion. a pressure sensor; and a seat back pressure sensor that is disposed between adjacent members of any one of the plate, air chamber, pad, and skin of the seat back and detects the pressure applied to the seat back. , an air supply means for supplying air pressure to each of the air chambers, and changing the air pressure supplied to each of the air chambers simultaneously or sequentially over time, and changing the pressure detected by each of the pressure sensors. A seat structure characterized by comprising: a controller that changes the air pressure supplied to each of the air chambers in accordance with the above.
