Abstract:
1. A shock absorbing system applicable to the bumper of a vehicle, comprising: a shock absorber comprising a deformable tube having one end joined to the bumper, and a retaining device of the absorber supported by a vehicle chassis, comprising a retaining mechanism susceptible to adopting at least one blocking position and one releasing position in which the retaining mechanism prevents and allows, respectively, the displacement of a retaining portion of the absorber in an axial direction with respect to the chassis in the event of a vehicle collision, wherein the retaining mechanism comprises two rotating retaining connecting rods symmetrically arranged around the deformable tube, connected to a common support and linked to one another, wherein a rotation of a first one of the connecting rods is transmitted to a second one of the connecting rods to achieve a similar movement but in an opposite direction, the connecting rods being able to rotate from a blocking position in which they interfere in the path of the absorber preventing the displacement of the retaining portion in the axial direction to a releasing position in which the connecting rods allow the displacement of the absorber with respect to the retaining device and consequently with respect to the chassis; and an electromechanical transducer transforming an electrical signal into a mechanical impulse, the electromechanical transducer connected to the retaining connecting rods so as to transmit a force that actuates the retaining connecting rods, when a predetermined electrical signal is received by the electromechanical transducer, an impulse sufficient to displace the retaining connecting rods from the at least one blocking position to the at least one releasing position almost instantaneously.
