Dynamic tests with energy absorbing seat belt restraints

Dynamic tests were carried out with lap sash seat belts in their conventional configuration, and with energy absorbers developed at the aeronautical research laboratories incorporated in the sash strap and seat mounting. The tests were done on the hyge crash simulator at the general motors holden's test centre near Melbourne. When tested with a sled acceleration of 240 m/s2 the forces in the straps of the energy absorbing system were 30% lower than those in the conventional system, and the seat force was approximately 50% lower. The forces in the energy absorbing system at a sled acceleration of 300 m/s2 were approximately the same as those developed in the conventional system at a sled acceleration of 180 m/s2. The "trade off" of reduced load against increased dummy movement with the energy absorbing system is indicated. (a)
