Abstract
An energy absorption device for a steering column for a motor vehicle may include a bending bracket for energy absorption in a crash event. The bending bracket may comprise a first fastening element and a second fastening element, with the first fastening element being displaceable relative to the second fastening element if, in a crash event, the bending bracket is deformed along a guide track delimited by a start and an end. The energy absorption device may further include one or more collision elements arranged on the guide track. An example collision element may interact with the first fastening element or an element on a retaining part that is secured to the first fastening element such that the collision element, the first fastening element, and/or the element on the retaining part are deformed and absorb additional energy.
