Abstract
The aim of the project was to investigate the relationship
between vehicle design and the nature and severity of occupant
injuries. A critical appraisal of the literature was made and a
detailed investigation was undertaken of 43 rollover crashes with
injury severity ranging from none to fatal. From the literature,
the weight of evidence indicated a relationship between roof crush
and occupant injury and a particular association between roof crush
and spinal cord injury.
The crash study generally supported these conclusions but also
identified factors which could lead to spinal cord injury when
there was small roof intrusion. Another injury mechanism was found
to be partial ejection of belted occupants leading to crushing head
injury. Recommendations for vehicle design improvements include
side window integrity, roof framing strength, geometric design of
door/roof framing, interior padding, restraint design and door
integrity.
