Airbag systems that must satisfy FMVSS 208 can only be optimized within narrow limits due to the passive restraint requirements.

An airbag system developed according to Standard 208 brings with it, with reference to aggressivity among other things, such serious disadvantages that, considering the very high belt usage rates, one cannot speak of such a system as optimized for the majority of vehicle occupants.

This presentation points out which problems originate from system development to meet passive requirements, as well as how an airbag can be optimized when it is designed as a restraint system supplemental to safety belts.
