Abstract	A quarter roll of a motor coach could result in fatal injuries to its occupants due to ejection and occupants striking each other and striking the bus interior. The best rational solution to prevent ejection and serious head injury is to restrain the occupants to their seats. This study addresses the dynamic performance of the portable restraint in a rollover accident and compares it to the conventional restraint. The biodynamic code MADYMO is used to analyze and compare the occupant kinematic with the portable restraint and the conventional restraint. The full scale bus rollover motion data with different ATD’s (Anthropomorphic test devices) placed at different locations on the bus shall be used to prescribe motion to this MADYMO model. This study demonstrates the success of the portable restraint in preventing ejections if the lateral belt used for securing the system to the seat does not slip. The study further demonstrates the possibility of improving the portable restraint performance using computational model.
