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.
A seat installation for a combat vehicle seat including a seat pan supported on a floor of said vehicle by a breakaway structure which connects said seat pan and said floor so as to initially cause said floor to drive up said seat pan immediately after an explosion occurs but thereafter disconnects said connection therebetween by breaking away quickly enough to thereby avoid an injurious spinal compression.
A seat installation for a combat vehicle seat, including a foot rest pivotally connected to a seat pan at a forward end thereof to allow an occupant's feet to rest thereon, said foot rest normally spaced above said floor, but pivoted up by contact with said floor caused by a severe explosion.
A seat installation for a combat vehicle including energy absorbing structures interposed between an undersurface of a seat pan of said seat and a floor of said vehicle, each of said energy absorbing structures comprising a plurality of hollow cells vertically stacked together atop each other.
