A General Discussion on Interior Design Alternatives in Response to FMVSS 201U-Upper Interior Head Impact Protection

The implementation of Federal Motor Vehicle Safety Standard (FMVSS) 201U-Upper Interior Head Impact Protection[1] will require significant changes to vehicle interiors. The response from the safety industry to this regulation has resulted in a number of new and innovative design solutions. These countermeasures include integrated trim components, foam, and other types of deformable structures. The challenge to the safety industry is to design the components to provide higher levels of head impact protection without sacrificing other important considerations such as vision, appearance, durability, and cost. This paper will present background information on FMVSS 201U testing, discuss various countermeasure concepts currently being implemented, and suggest design alternatives relative to specific regions in a given vehicle.
