摘要
A seat installation for a combat vehicle which protects an occupant from the effects of an explosion detonated beneath the vehicle in which breakaway structures are interposed between a seat pan and the vehicle floor which initially rapidly drives the seat up after the explosion, but which quickly breaks away to avoid spinal compression injury. A crushable energy absorbing structures thereafter absorb the floor motion, each structure comprised with a vertical stack of crushable energy absorbing cells which are successively crushed at higher force levels to adapt the seat installation to varying weight occupants. A pivoted foot rest provides spaced above the floor which mitigates injuries to the feet and legs by allowing the feet to avoid contact with the floor and which swing up and away from the floor while avoiding tipping of the seat.
