A large area of the vehicle floor between the front- and rear bumper is exploited to accommodate at least one deformable element. Its front- and rear portion is connected to a pair of front- and rear piston devices, which independently operate to defor m the deformable element in any front- or rear collision. The deformable element is subdivided into a number of crushable segments, provided with sites of predetermined fracture, which, in juxtaposition, have inequal stiffness in order to control the rate of deceleration. Engaging receptacles and mating keys of interengaging assemblies define the crushable segments of the first deformable element, responsible for energy-absorption in a front- or rear collision, and the second deformable element, responsible for energy-absorption in a side collision. An upper and lower deformable floor of trunk-compartment, a pair of runners and a pair of wheel cases define storage-rooms, covered by the respective releasable upper floor.
