Abstract
Abstract A VEHICLE SAFETY HARNESS ASSEMBLY INCLUDES SHOULDER STRAPS INTERCONNECTED WITH A SLIDABLE CONUNTERWEIGHT LOCATED EITHER BENEATH THE SEAT OR BEHIND IT. UPON ABRUPT DECELERATION, THE COUNTERWEIGHT IS THRUST FORWARDLY WITH A GREATER FORCE THAN THE UPPER BODY PORTION OF THE USER AND THUS SWIFTLY EXERTS TENSION ON THE STRAPS SO THAT THE USER IS PULLED REARWARDLY AGAINST THE BACKREST WHERE HE IS RE- STRAINED FROM FORWARD MOVEMENT UNTIL THE PERIOD OF HARMFUL DECELERATION HAS ELAPSED. AN UNDERLYING SUPPORT PLATFORM FOR THE COUNTERWEIGHT MAY BE SLOPED TO ADJUST THE HORIZONTAL FORCE COMPONENT OF THE COUNTERWEIGHT TO ACCOMMODATE THE VARYING NEEDS OF DIFFERENT USERS.
