A SYSTEM FOR ISOLATING A BODY SHOCK IMPULSES TRANSMITTED THROUGH ITS SUPPORTING ENVIRONMENT COMPRISING: A PNEUMATIC SPRING CONNECTED BETWEEN THE SUPPORTING ENVIRONMENT AND THE BODY TO BE ISOLATED AND COMPRESSED, BY SUPPORTING THE MASS OF SAID BODY, TO A STATIC GAS VOLUME AND PRESSURE; A GAS RESERVOIR HAVING A FIXED VOLUME AT LEAST AS LARGE AS THAT OF SAID PNEUMATIC SPRING AND PRESSURIZED TO SAID STATIC PRESSURE; CONTROLLABLE FLOW MEANS COUPLED BETWEEN SAID PNEUMATIC SPRING AND SAID GAS RESERVOIR; CONTROL MEANS COUPLED TO SAID CONTROLLABLE FLOW MEANS; PRESSURE SENSING MEANS COUPLED TO SAID CONTROL MEANS, SAID SPRING, AND SAID RESERVOIR SENSITIVE TO PRESSURE DIFFERENTIALS BETWEEN SAID PNEUMATIC SPRING AND SAID RESERVOIR TO CASUSE SAID CONTROL MEANS TO CONTROL, IN QUANTITY AND DIRECTION, GAS FLOW FROM SAID PNEUMATIC SPRING TO SAID RESERVOIR WHEN THE INSTANTANEOUS PRESSURE IN SAID PNEUMATIC SPRING IS GREATER THAN SAID PREDETERMINED PRESSURE BY A PREDETERMINED DEGREE AND FOR PERMITTING GAS FLOW FROM SAID RESERVOIR TO SAID PNEUMATIC SPRING WHEN THE INSTANTANEOUS PRESSURE THEREIN IS LESS BY A PREDETERMINED DEGREE THAN SAID PREDETERMINED PRESSURE, WHEREBY THE PRESSURE AND VOLUME OF SAID COMPRESSED GAS IN SAID PNEUMATIC SPRING MAY BE HYSTERETICALLY CYCLED TO COUPLE THE ENERGY OF SAID TRANSMITTED SHOCK IMPULSES THERMODYNAMICALLY TO THE GAS IN SAID RESERVOIR.
