A racing helmet is a form of protective headgear worn by racing car and rally drivers. Motor racing has long been known to be an exceptionally risky sport:[1] sudden deceleration forces on the head can easily occur if a racing car loses control at the very high speeds of competitive motor racing or the rough terrain experienced in rallying.[1] A risk more nearly unique to motor racing is the possibility of drastically severe burns from fuel igniting when the fuel lines or fuel tank of the vehicle are jolted sufficiently to dislodge or breach them in a situation in which the driver cannot soon enough escape from his car. This happened to world champion driver Niki Lauda at the 1976 German Grand Prix race at the Nürburgring in a crash from which he barely escaped alive.
It is known that the percentage of racing accidents resulting in hospitalisation in motor racing, at around 25 percent, is higher than any other major international sport[2] and that the average period in hospital is the longest. A recent Australian study also suggests motor racing may have the highest rate of actual injury among major sports.[3] However, a study conducted between 1996 and 2000 by Fuji Toranomon Orthopaedic Hospital in Shizuoka suggests that only a small proportion of these injuries are actually to the head or surrounding areas.[4]
