Despite the development of efficient individual protective means such as crash helmets and padded outfits, motorcyclists represent a high risk group. This is why it was proposed to complete this protection with devices integral with the motorbike: leg protectors and the air bag. The aim of the motorbike air-bag is to form a screen between the driver and the obstacle which he is likely to crash into when thrown off his machine. However, it is advisable to check the effect of the inflation when the driver's head is close to it. This is the purpose of this study in which 4 tests were carried out using corpses. These were instrumented to evaluate the violence of the shock received and high speed camera made it possible to determine the cinematic. Finally, medical imaging and autopsy enabled an exhaustive evaluation of the lesion to be made, and determine the seriousness of the lesions received. Checks were carried out using human corpses, to determine if the sudden application of an inflatable bag in front of a motorbike during an impact is likely to cause accelerations and/or injuries to the head or backbone. This is done by using cinematographic methods of acceleration measurements and medical examinations. (A)
