Seat assembly

A method of operating a seat assembly including a seat having a plurality of regions, a seat actuator connected to the seat, a sensor assembly connected to the seat, and an electrical control unit (ECU) operatively connected to the seat actuator and the sensor assembly, the sensor assembly including a pressure sensor array connected to the seat, the method comprising:

• obtaining information about a user via an occupant sensor of the sensor assembly;
• generating a model for at least one portion of a body of said user based on the obtained information;
• determining, via the ECU, an expected composition of soft tissue of said at least one portion of said body that is associated with the plurality of regions of the seat based on the model;
• detecting a pressure applied to the seat by said user via the sensor assembly;
• comparing the detected pressure to a pressure threshold via the ECU;
• and
• if the detected pressure exceeds the pressure threshold, reducing soft tissue stress in said soft tissue of said user via adjusting the seat via the seat actuator;
• wherein the plurality of regions are subjected to a respective localized pressure by the pressure applied to the seat by said user;
• and
• detecting the pressure applied to the seat includes detecting the respective localized pressures of the plurality of regions of the seat via the pressure sensor array.
