Active seat suspension failsafe operation

An active seat suspension of a vehicle comprising:

• at least one actuator constructed to be operatively coupled to a seat to control movement of the seat in at least one direction relative to an underlying portion of the vehicle;
• and
• a controller operatively coupled to the at least one actuator, wherein the controller is constructed and arranged to detect a failure state of the active seat suspension, and wherein the controller is constructed and arranged to limit operation of the at least one actuator in response to the detected failure state.

A method of operating an active seat suspension in a vehicle, the method comprising:

• detecting a crash or imminent crash of the vehicle;
• and
• operating the active seat suspension to lower a seat connected to the active seat suspension toward an underlying portion of the vehicle in response to the detected crash or imminent crash of the vehicle.

An active seat suspension of a vehicle comprising:

• at least one actuator constructed to be operatively coupled to the seat to control movement of the seat in at least heave;
• and
• a controller operatively coupled to the at least one actuator, wherein the controller is constructed and arranged to detect a crash or imminent crash of the vehicle, and wherein the controller is constructed and arranged to operate the at least one actuator to lower the seat toward an underlying portion of the vehicle in response to the detected crash or imminent crash of the vehicle.
