A structure for absorbing energy from impacts thereon, the structure being plastically deformable by an impact, with, if appropriate, the possibility that it is at least to some extent disrupted. The structure can include a) ribs for reinforcement, the ribs arranged with respect to one another at an angle with respect to the axial direction such that on failure of a rib a force acting on the structure is immediately absorbed axially by another rib, b) ribs running axially, the ribs being in essence corrugated or of zigzag shape, c) at least one rib running axially in a first plane and connected to at least two ribs running axially in a second plane rotated with respect to the first plane. The structure includes, in the direction of impact, at least two layers, each of which has different compressibility properties and different failure properties.

Structure for absorbing energy

A bumper system for a motor vehicle includes, but is not limited to, a bumper cross member, which is fixed to a stiff frame of the motor vehicle, a pliable bumper shell, a compressible structure which is formed between an upper area of the shell and the cross member and one support section which supports the lower area of the shell, which, together with a crash box holding the cross member is anchored to the flange plates of the frame.
