A new crash test device has been developed, called “Repeatable Pete.” It is a repeatable, durable anthropomorphic dummy with humanlike dynamic performance. This paper describes the device and gives details of its design and performance during testing in automotive situations. The head, neck, and chest match the latest biomechanical information on the dynamic responses of unembalmed cadavers. The head c.g. accelerations adequately match the skull acceleration, so that head injury criteria based upon cadaver skull acceleration may be used.

This paper discusses the development of adequate criteria and evaluation methods for seat belt restraint design. These criteria should include the effect of seat belts in abdominal injury as well as head injury. It is concluded that belt load limiters and energy-absorbing devices should limit head-to-vehicle contact, ensure that the lap belt maintains proper contact with the bony pelvic girdle, and limit the belt loads. Studies are made of pulse shape and belt fabrics. Currently available mathematical models are used for the studies included in the paper.
