Die haeufigsten Verletzungen bei Unfaellen von Motorradfahrern betreffen vorwiegend die unteren Extremitaeten. Die vorliegende Studie behandelt Moeglichkeiten des Beinschutzes durch spezielle Systeme der Schutzkleidung, so genannte Protektoren. Diese bestehen sowohl aus stossdaempfendem Schaumstoffmaterial als auch aus Hartschalen, die mit dem Schaumstoff verbunden sind. Durch biomechanische Versuche an Leichnamen mittels aufschlagendem Pendel konnte die stossdaempfende Wirkung von Beinprotektoren auf das Entstehungsbild von Unterschenkelbruechen nachgewiesen werden, wobei sich die maximale Stossbelastung um etwa 40 Prozent reduzieren liess. (Author/publisher) Abstract in English: This study has considered demands placed on protective clothes for motorcyclists together with observed benefits and limitations for absorbing loads and preventing injuries. In this study, 1,933 accidents involving injured motorcyclists, collected by an in-depth investigation team at ARU-MUH, were analysed to find the detailed injury patterns comparing persons with and without protective clothes. The parameters influencing the force reduction are discussed comparing impact speed, elasticity coefficient and thickness of the materials used in special protectors. Additionally, post mortem human tests were carried out to find the effectiveness of such protector devices for load reductions in the lower leg. This study showed that loads, and the subsequent risk of fractures, can be reduced efficiently by foamplate systems. Benefits were established for using a laminate of hard and soft materials for protection against soft tissue injuries both in the accident analysis and experimental tests. (Author/publisher).
