IMPROVEMENTS TO AIRCRAFT SAFETY SEATS An aircraft seat is supported upon arcuately curved legs of a suitable alloy to remain rigid under normal conditions. When stress occurs due to an aircraft mishap, the seat and occupant tips forwardly with the front legs flexing or partially collapsing while the rear legs extend, both actions restricting and controlling the forward movement of the seat induced by a collision or crash. The seat back which also bends forwardly under stress of collision or crash also incorporates an arcuately curved bar of similar material to alleviate stress upon the body of the passenger held in place by a shoulder and lap harness.
