Ford Motor Company introduced the automotive industry’s first second row inflatable seatbelt system in 2011. The system is currently available in the outboard seating positions of the second row of several Ford and Lincoln models. An important consideration for this system is the interaction with child restraint systems (CRS) when it is used to install a CRS or used in conjunction with belt position booster. A novel test methodology to assess the interaction of CRS with Ford and Lincoln inflatable seatbelts through frontal impact sled tests is explained. Details of test methods including construction of additional fixtures and hardware are highlighted. This procedure is designed to enable test labs capable of running Federal Motor Vehicle Safety Standard (FMVSS) 213 testing to adapt this test method, with minimal fabrication, by utilizing existing test benches. The test methodology can be used to quantify the effect of the Ford and Lincoln inflatable seatbelt compared to a standard seatbelt on CRS in terms of Anthropomorphic Test Device (ATD) responses and CRS and ATD kinematics as well as assess the effect on CRS system integrity. Sample results are presented for various CRS types.
