[Bicycle accidents of children]

Bicycles are funny and stimulating sport and play tools for children but riding a bicycle brings also a lot of risks. The most frequent causes of injuries, the accident patterns, the seriousness and patterns of injuries were examined by means of two investigations of 823 children injured in bicycle accidents. The safety consciousness of children and parents was evaluated as well. Three sources of danger were found to be the most frequent causes of accidents: "the agent" (bicycle), "the environment" (situations) and "psychodynamic risk factors" (behaviour). Prevention measure for all three sources of danger will be discussed. The use of bicycle helmets as simple, cheap and efficient protective measure is recommended in particular.
