Abstract: The present invention relates to a three-wheel monocoque motorbike-type vehicle designed to increase the survival of persons (users or pedestrians) in the event of an accident. The vehicle is characterized by its inverted-tricycle configuration and is provided with: a monocoque chassis (1) to protect the users from injury in the event of accidents; safety seats provided with retaining systems (8) and mechanical detachment (9) from the chassis of the vehicle to prevent the direct transmission of energy from collisions; and systems for absorbing the energy of impact in order to protect the users (4, 5, 6) and pedestrians (7).
