Abstract

The crashworthiness of occupied proprietary wheelchairs, which are transported in motor vehicles, is currently assessed by physical crash testing in accordance with ISO 7176-19. If such wheelchairs are modified to meet the needs of the occupant, e.g. the addition of special seating, environmental control systems or life support equipment, then those making the modifications take on the manufacturer's responsibilities, one of these being the assessment of the modified wheelchair's ability to withstand vehicle crash forces. Destructively testing bespoke wheelchair designs is not practical so, currently, the transport-related risk is assessed using best engineering judgement. To improve this process virtual crash testing of the wheelchair and occupant was used. A modified crash criteria from ISO 7176-19 is proposed to enable assessment of the wheelchair's crashworthiness and provide the clinical engineer with an informed judgement of how both wheelchair alone and occupant and wheelchair together will behave in a crash.
