Energy absorbing and sizing means for helmets
Abstract
Abstract A SYSTEM FOR ABSORBING ENERGY TO AVOID THE DETRIMENTAL EFFECTS OF IMPACTS IN PROTECTIVE EQUIPMENT SUCH AS HELMETS COMPRISING A PLURALITY OF FIRST CHAMBERS LOCATED ON THE INSIDE SURFACE OF THE HELMET FOR POSITIONING ADJACENT THE HEAD OF THE WEARER. A SUBSTANTIALLY NON-COMPRESSIBLE FLUID IS INCLUDED WITHIN THESE FIRST CHAMBERS, AND CONDUITS CONNECT THE FIRST CHAMBERS WITH CORRESPONDING SECOND CHAMBERS. UPON IMPACT, FLUID IS DISPLACED TO THE SECONE CHAMBERS, AND, DUE TO THE DESIGN OF THE CHAMBERS, THE DISPLACED FLUID IS RETURNED TO THE FIRST CHAMBERS WHEN THE FORCE OF THE IMPACT IS REMOVED. SIZING MEANS USEFUL WITH THE ENERGY ABSORBING MEANS OR IN OTHER APPLICATIONS ARE LOCATED ON THE INTERIOR OF THE HELMET SURFACE. THE SIZING MEANS INCLUDE EXPANDABLE COMPARTMENTS, AND VALVES ARE ASSOCIATED WITH THESE COMPARTMENTS WHEREBY A USER OF THE HELMET CAN PLACE THE HELMET ON HIS HEAD AFTER WHICH AIR IS INTRODUCED INTO THE COMPARTMENTS UNTIL A PROPER FIT IS ACHIEVED. ENERGY ABSORBING PADS ARE PREFERABLY LOCATED WITHIN THE COMPARTMENTS TO SERVE AS ADDITIONAL SAFEGUARDS UNDER HIGH IMPACT CONDITIONS.
