IMPROVED SYSTEM FOR ABSORBING IMPACTS IN MOTOR VEHICLES

Improved system for absorbing impacts in motor vehicles consisting of coupling solidly to the vehicle body front beams which are intended to receive the impacts and deformable devices which are secured to the rear part of the body structure and which are intended to absorb strains. The front beams and the rear deformable devices are connected and hinged by a cable which is guided by a pulley provided at the front of the car; the pulley is characterized in that its support shaft is designed with a structure which can be progressively deformed longitudinally by the cable tension upon an impact with the aim to determine an appropriate displacement of the pulley towards the rear part of the vehicle, in accordance with its specific function.
