Abstract:This study uses computer models to study how unconventional seating positions and orientations such as those conceptualized to be offered in vehicles with Automated Driving Systems may affect occupant response metrics of children restrained by child restraint systems (CRS) equipped with internal harnesses (CRS harness-restrained) or the vehicle lap-shoulder belt, with and without belt-positioning boosters. A total of 550 simulations were conducted with the CRABI 12MO in rear-facing CRS, the H33YO in both rear-facing and forward-facing CRS, the H36YO in a backless booster, and the H310YO with and without a booster across a range of conventional and unconventional seating locations and orientations under five impact directions and various CRS installation methods. This is the first study using different child ATDs and CRSs to investigate child occupant responses in a wide range of impact directions and seating orientations.
