Title: Blast attenuation seat

Abstract: A seat for supporting an occupant of a vehicle and absorbing a force between the occupant and the vehicle created by relative movement between the occupant and the vehicle including a seat bottom and a seat back extending from the seat bottom. At least one of the seat bottom and the seat back includes a first energy absorbing device for absorbing at least a portion of the force when the force reaches a first magnitude. The one of the seat bottom and the seat back also includes a second energy absorbing device for absorbing at least a portion of the force when the force reaches a second magnitude greater than the first magnitude. The second energy absorbing device supports the first energy absorbing device so that the first energy absorbing device transmits a portion of the force to the second energy absorbing device when the force reaches the second magnitude.
