The on-going industry effort to improve air bag systems for out-of-position occupants has created the need to reexamine the existing design criteria and development means to be used in the implementation of advanced air bag technologies. Development procedures and test techniques must be augmented to include appropriate testing of the out-of-position occupant. This paper will review the development of a unique dynamic test fixture and test methodology to simulate the pre-deployment movement of an occupant concantenated with a conventional crash pulse on a HYGE sled. This test methodology provides for efficient development of dynamic occupant tracking systems, biomechanic algorithms and restraint system controls.

This paper is a compilation of work whose goal is to integrate Computer Aided Engineering CAE software to model occupant injury. The work focuses on three major simulation environments that together can model the overall Intelligent Restraint System. The first software is called MADYMO and is mainly used to predict the occupant kinematics and calculate injury criteria. The second is Saber, which is used to model and predict sensing system behaviors. The third is MATLAB, which is used to calculate restraint settings from derived sensor data. The blend of these three software environments provides for a more complete understanding of an advanced restraint system.
