| Abstract |
The Provision and Use of Work Equipment Regulations 1998 (PUWER, see CIS 99-1429) requires an employer in Great Britain to fit seat restraints to tractors. Two-point lap belts are the only means of providing this protection in retrofitted existing tractors, since the fitting of restraints such as a three-point harness would involve drilling or welding fittings to the safety cab, which is illegal unless approved by the original manufacturer. In order to develop a better understanding of the effectiveness of lap straps, a numerical model of a overturning tractor was developed and used to provide a comparative analysis of the likely injuries to a restrained and unrestrained operator for a number of overturning scenarios. The model was based on the dimensions of a commercially-available tractor, which was also used for the validation tests. It was found that the body regions most likely to be injured would be the head and neck due to impact with the cab interior and, in addition, the lumbar spine for the restrained operator. |
