ABSTRACT:
A support system for an object such as a crashworthy aircraft crew seat which is floor mounted will isolate the seat from floor distortions as well as floor vibrations which would otherwise be introduced into the seat. The floor distortions occur only during a severe crash or impact. The floor vibrations occur continuously during normal flight as well as during maneuvers which could increase or decrease from a nominal level of relatively high G forces as they are transmitted from the floor. The invention provides a plurality of vibration and distortion isolating units from which the chair is supported at a plurality of points. The isolation units are circular holding members made of resilient material with crushable metal inserts in the resilient material. Supporting pins or members pass through the metal inserts in the isolation units. The isolation units are carried by rail guides constructed to translate along rails. The isolation units provide the capability of plus or minus 10.degree. of bending movement of a rail or plus or minus 10.degree. of twisting movement of a rail which movements are isolated from the chair.
