Abstract
A component which is to be installed for an absorption of energy with an ideal displacement-compressive force characteristic consists of a prismatic straight metal rod, which is long relative to its transverse dimensions and is adapted to inelastically buckle in the direction of the axis of its larger principal moment of inertia under an axially acting compressive load and is provided with spur teeth, which extend transversely to the longitudinal direction and are provided on at least one of the broadsides, which extend at right angles to the axis of the larger principal moment of inertia.

A component for absorbing energy, having a prismatic straight metal rod (1, 5, 10, 12), which is long relative to its transverse dimensions and is adapted to inelastically buckle in the direction of the axis of its larger principal moment of inertia under an axially acting compressive load and is provided with spur teeth (4, 7, 11, 13), which extend transversely to the longitudinal direction and are provided on at least one of the broadsides, which extend at right angles to the axis of the larger principal moment of inertia.
