Vehicle manufacturers are developing dynamically deploying upper interior head protection systems to provide added occupant protection in lateral crashes. These devices are used to protect the head and neck areas and to prevent ejection from the vehicle. The National Highway Traffic Safety Administration (NHTSA) has established requirements in Federal Motor Vehicle Safety Standard (FMVSS) 201 [1] for these systems. This paper will discuss testing methodologies in the areas of component testing of curtain-type side airbag systems and full scale side impact testing of a vehicle into a rigid pole. These testing methodologies have been created as a direct result of the development phase of several airbag systems. Prior to pole impact testing, tests have been developed which evaluate these types of systems for characteristics such as inflation time, fill capacity, and how long the system stays inflated during side impact and rollover simulations.
