Abstract: It is characterized by a cage structure (4, 5, 6, 7, 8, 9, 10, 11, 14) fitted with safety belts that can be simply attached or rested on supports (1, 2, 3, 15) and fixed onto motorcycles, moto scooters, tricycles or ATVs, and which can be ejected through impact of any eventual accidents. It is composed of modules (4, 6, 8, 10, 11, 12, 14) that have bends or sharp curves, which are joined using two plates (5, 9), one on either side, which can be molded around the curves and fastened onto one another, without the need for drilling holes in the tubes, thus maintaining their overall strength. The top module (8) and the side shields (19) can have a hood made of a malleable material, with covered Styrofoam plates on the inside, reinforced with strips made of rubber, plastic or a similar material.
