Abstract
A company was commissioned to design five prototype seats with new features such as increased back padding, more flexible seatbacks, and a variety of restraint system types. Transport Canada then requested the Impact Studies Facility of the Defence and Civil Institute of Environmental Medicine (DCIEM) to conduct 20 simulated impacts, using the HyGe Facility, with these seats oriented in both the frontal and 30 degrees from frontal directions. The objective was to determine and compare the dynamic performance of the prototypes with the standard bus seat, primarily in terms of the head and chest decelerations, the Head Injury Criteria (HIC), and other measured dummy parameters. The tests showed that only 3- and 4-point restraint systems were capable of preventing head impact with the more forward seat, thereby reducing HIC values well below 1000, at which level serious injury is assumed to occur.
