A simple yet reliable apparatus is disclosed for dissipating sudden impacts or applications of force. Sudden impacts are dissipated through the sequential shearing of rods or pins anchored perpendicularly to the incoming force and through the compression and evacuation of gel through holes or valves in a cylinder. By varying the diameter and length of the cylinder, pistons, the number size and composition of shear pins, the number and size of restriction holes and or the amount of gel, the system can reliably dissipate impacts within predetermined limits.
