A system and method for delivering an axial compression load to a passenger during a frontal deceleration event is disclosed. The system includes a seat frame, a seat pan, and an impulse generator coupled to the seat pan configured to provide an axial compression load onto a spine of a sitting passenger during a forward deceleration event. The system further includes a controller configured to receive a forward deceleration signal from the inertial sensor and activate the impulse generator based on the forward deceleration signal. The impulse generator may generate a compressive force via a chemical reaction, via a mechanically stored energy, a solenoid switch, or via a rotating cam assembly.
