Shock absorbing system applicable to the bumper of a vehicle

摘要

The invention relates to a shock absorbing system applicable to the bumper of a vehicle comprising a shock absorber with a deformable tube joined at one of its ends to the element of the vehicle which acts as a bumper, and a retaining device of the absorber comprising a mechanism susceptible to adopting at least one blocking position and one releasing position in which it prevents and allows, respectively, the displacement of a retaining portion of the absorber in an axial direction. The aforementioned mechanism comprises two rotating retaining connecting rods in a plane perpendicular to the longitudinal axis of the deformable tube, connected to a common support and linked to one another such that the rotation of any one of the connecting rods is transmitted to the other to achieve a similar movement but in the opposite direction; and an electromechanical transducer connected to the retaining connecting rods for the purpose of transmitting to them, when a predetermined electrical signal is received, an impulse sufficient to displace them such that the mechanism goes from adopting a blocking position to a releasing position almost instantaneously.
