Abstract

This invention relates to an improved shock-absorber device (6) comprising numerous small hollow flexible walled bodies which are preferably at least paritally gas-filled and are suspended in a liquid or gel medium and confined by a flexible walled vessel (1) or piston and cylinder arrangement. The device reduces the energy of impacts and also exploits the hydraulic properties of liquids to spread the force of an impact over a wider area. Many variations of the device of interest to travel, sports, medical, manufacturing and civil engineering industries are described. It offers a novel solution to the problem of exploding fuel tanks in aircraft and new methods of improving safety and comfort in motor vehicles. A 'smart' active version of the device is also proposed.
