Abstract
This sled test series involved occupant loading of the seat in rear crashes of 4.3-8.3 m/s (9.6-18.5 mph). The tests were conducted in the early 1980s and involved an unbelted or lap-shoulder belted Part 572 dummy in rear and oblique rear impacts. The research is reported today to provide comparative data for the record and serves as a control benchmark for more current technologies and safety research methodologies on seat performance in rear crashes. Safety belts improved occupant retention on the seat primarily by the lap belt reducing the upward and rearward movement of the pelvis. Tests were also conducted on the mechanisms for energy absorption by seatback deflection.
