1. An energy absorption device for arrangement between a fastening device and a holder, wherein the holder is movable relative to the fastening device when a predetermined impact force is exceeded, with a deformable strand for absorbing energy, and with a guide device for guiding the strand during a deformation, wherein the strand and the guide device are designed as a one piece element and wherein the strand is U-shaped with a first leg and a second leg, wherein the first leg is shorter than the second leg in an initial position, and after a deformation of the strand in relation to the initial position due to an absorption of energy, the first leg being lengthened and the second leg being shortened; and wherein the guide device has a first guide section and a second guide section, wherein at least during the deformation of the strand the first leg of the strand rests against the first guide section and the second leg of the strand rests against the second guide section.
