The continuing study of motorcycle riding gear carried out by Dainese has led to the development of a system of protective riding gear with an integrated air-bag. The aim of this system is not only to reduce the injuries to a rider due to impacts with opposing objects but also to prevent direct contact with the terrain caused by accidental falls.

The scope of this research was to use a multi-body code to simulate the fall of the motorcycle-rider system to determine which parameters can be useful in identifying the early stage of fall. Determining such parameters will be used to develop a logic of control able to activate a passive system of protection, a type of air-bag, included both on the motorcycle and in the rider’s protective gear. The rider model was based on a crash test dummy scheme. Dynamic behavior of the system was analyzed in diverse critical conditions. As a result useful information regarding possible crash events was collected.
