Abstract
Device for absorbing kinetic energy of a moving body includes a plastically deformable helical spring having a stack of convolutions, the inner surfaces of which delimit a passage. At least a part of the convolutions can be pulled successively through the passage. Due to the resulting deformation of the convolutions, energy can be absorbed.
