The protection of the vest against impacts is effective only when it is fully inflated and that the closure must be correctly closed (zip to the top and snap button or plastic buckles are all closed). It is imperative to connect the vest to the motorcycle or scooter in order to start the inflation of the vest and to be protected.
The Airbag device is used to prepare the impact and minimise its consequences without however providing an absolute protection against all wounds, it inflates close to the body to rigidify and maintain the top for neutral position, while the energy impact of the shock is absorbed and dissipated along all the surface of the device.
