摘要

Passive safety system for the case of a frontal impact of a pedestrian on a hood of a vehicle, comprising means for the ejection of the rear part of the hood in the case of a pedestrian - impact, as well as means for absorbing impact energy of the pedestrian -, wherein the means for absorbing impact energy of the pedestrian - have two devices, which in the closed position of the hood are in contact with each other, namely:– a deformable catch device (6) for absorbing the energy of a pedestrian - impact, which in the interior or a sub-structure (1a) of the hood (1) by means of a centering axis (8), which is fastened by a concentric cylindrical closing stop (10) is provided with rings, as well as an outer tube (11) in the form of a deformable bellows and with a smaller length than the of the stop (10) is surrounded;– and a retractable support device (7), around the deformation of the catch device (6) in the case of a pedestrian - impact, which on a fixed cross member (5) of the vehicle is secured and from a support base (12) with..
