In this study, the German In-Depth Accident Study (GIDAS) data from the year 1999 - 2009 was used for the analysis of far-side crashes, restricted to belted, front seated passenger car occupants not involved in a rollover. The dataset was weighted to the national statistics of the corresponding years. Front seat occupants had nearly the same exposure to near- and far-side impacts, whereas MAIS3+ injured occupants were seated to one-third on the far-side and to two-third on the near-side. About twenty-five percent of the side impact fatalities were seated on the far-side. These ratios are in the same magnitude to those presented by the analysis of NASS/CDS data. Most severe injured far-side occupants sustained severe injuries to the thorax (56%) and the head (50%) due to contact with the (intruded) far-side structure, the seat belt, the adjacent seat structure or, if applicable, the adjacent occupant. Forty-one percent of the AIS3+ injuries were found in the thorax region and 38% in the head region. Upper and lower extremities accounted for 10%. Percentages from US data for the thorax and head region were lower (33% and 21%) while percentages for the extremities were higher (30%). In GDDAS over 40% of the collision opponents for MAIS3+F injured far-side occupants were fixed objects whereas US data analysis showed only about 18% of these collision opponents. The distribution of ΔV had a substantial higher mean value in the German dataset for MAIS3+F injured far-side occupants compared to US data. As a result the opportunities for MAIS3+F mitigation for a ΔV range from zero to a specific value were smaller than the percentages that have been previously published based on NASS/CDS data. Nevertheless, up to the level of lateral ΔV present in current legal and rating side-impact tests the corresponding percentages of severely injured occupants seated near- and far-side are nearly the same. Except the differences in the collision opponent type and the distribution of ΔV the results from this study confirm the previously results based on US data. In general the test methods derived from the US data and therefore also the proposed countermeasures can be adapted to the European far-side impact protection evaluation. The difference in the distributions of lateral ΔV derived from German and US data should be investigated more in detail, when a larger data sample is available.
