Paper discusses the development of a Universal Docking Interface Geometry (UDIG), which enables independent wheelchair securement for people traveling in motor vehicles. Docking securement devices can be permanently mounted to the vehicle floor and engaged with a compatible adapter that is attached to the rear of a wheelchair. Computer simulations were conducted to determine the impact of UDIG placement. The simulations were conducted using Dynaman Version 4.0 and a validated model of a standard manual wheelchair. A male Hybrid III test dummy was used to represent a person occupying a wheelchair. Frontal and side impacts were simulated to measure horizontal, vertical, and lateral displacement. Results are displayed in table format. For all proposed UDIG adapter placements, forward wheelchair and occupant excursions remained within safe limits. Wheelchair and occupant kinematics stayed well within the excursion limits for frontal impact when using the UDIG with a manual wheelchair. Implications for further research are discussed.
