The conclusions arising from the first two stages of the crashworthy seat development programme were as follows: The height of the top of the seat back should be at least 0.025 m above the level of the centre of gravity of the 95th percentile male head. The dimension from the floor for the failure initiator should be at least 0.100 m above the centre of the knee impact point on the seat back for a 95th percentile male. The surface at the top of the seat back at and above the point of impact of a 5th percentile female should be flat. The failure initiator could be cold formed by a simple semi-circular shaped tool. The depth of seat frame material remaining, after forming the initiator, should not be less than 13.5 mm. The modified seat frame is compliant with the static load requirements of the Railtrack Code of Practice GM/RC 2502. Dynamic testing of the modified seat frame resulted in predicted injury levels within the proposed limits of passenger injury criteria.
