Abstract: A protective structure for vehicles, comprising at least one crosspiece external lined by a bumper strip and attached to a pair of longitudinal side-rails of the chassis of a vehicle by a pair of sacrificial elements. The protective structure also comprises at least one absorption element situated in the space defined by the crosspiece, the sacrificial elements and a bottom wall of the vehicle positioned between the two-side rails.

Abstract: A bumper assembly for a vehicle and the corresponding vehicle comprising said bumper assembly are described. The assembly comprises: at least two crash boxes; a cross member made of a first plastic material which, during use, extends over a distance at least corresponding to that between the crash boxes; and at least two substantially indeformable connecting devices connected to said cross member for rigidly fixing said cross member to said chassis of the vehicle, wherein said at least two substantially indeformable connecting devices are connected to the cross member at positions corresponding to the crash boxes. In a preferred embodiment, the crash boxes and the connecting devices are made of plastic material.

Abstract: Protective structure for vehicles, suitable for being used, in particular, in the case of collision between a vehicle and a pedestrian, of the type comprising at least a bumper strip (2), for the protection of the vehicle, comprising a lower portion (21) and an upper portion (22). The upper portion protrudes outwards with respect to the lower portion and comprises a buffer (T). The structure also comprises at least one reinforcement (3) situated inside said lower portion of the bumper strip.

Abstract: A bumper assembly for a vehicle and the corresponding vehicle comprising said bumper assembly are described. The assembly comprises: at least two crash boxes; a cross member made of a first plastic material which, during use, extends over a distance at least corresponding to that between the crash boxes; and at least two substantially indeformable connecting devices connected to said cross member for rigidly fixing said cross member to said chassis of the vehicle, wherein said at least two substantially indeformable connecting devices are connected to the cross member at positions corresponding to the crash boxes. In a preferred embodiment, the crash boxes and the connecting devices are made of plastic material.

Abstract: A protective structure for vehicles that uses at least one front cross member (17A), flat or shaped, made of metal or plastic, featuring at least one first absorber element or buffer (16), connected externally after the cross member (17A), and/or at least one second absorber element (25), positioned internally, in order to increase energy absorption during impact with respect to traditional structures. The structure can incorporate one or more buffers (16) designed, in particular, to absorb impact between vehicles and pedestrians (so-called pedestrian impact).

Abstract: A bonnet structure for automobiles with improved safety characteristics, in particular in the case of collisions in road accidents between automobiles and pedestrians, comprising at least one absorbency element (14), made for example from expanded polypropylene, expanded polyurethane or in a honey comb, placed between the outer surface (10) and the lower or inner surface (11) of the bonnet; the absorbency element (14) can be fixed through gluing or other mechanical connection means and, moreover, it is possible to foresee placing a material (16) with strong resistance to traction and with zero or almost zero bending moment on at least one of the sides of the absorbency element (14), in order to connect the outer and inner surfaces (10, 11) of the bonnet more firmly and to improve local resistance to breaking of the absorbency element (14).

Abstract: A protective structure for vehicles (10), designed to be used, in particular, in the event of impact between a vehicle (10) and a pedestrian (so-called pedestrian impact), in which at least one energy absorption element or buffer (16) is used, positioned, at least partially, parallel to the front cross member (17) of the vehicle (10); it is furthermore possible to modify the external style (L) of the vehicle (10), by bringing the profile of the bonnet (11) forward and/or furthermore providing for the insertion of a new buffer (25), designed to work on the front-end structure of the vehicle (10), positioned below the bumper (12), in order to obtain advantages in terms of safety.

Abstract: An impact energy absorption system for vehicles, comprising a cross member (16) housing a series of composite alveolar structures or buffers (10, 10A) which co-operate with an element (14) made of foamed plastic resin; the alveolar structure (10, 10A) is made of plastic resin preferably derived from polycarbonate and can feature a taper at at least one of the longitudinal ends where a containment element (22) can be provided.
