Abstract
A steering column for a motor vehicle has an adjustment unit (4) which bears a section of the steering shaft (1) and which, in the open state of a locking apparatus (7), is pivotable relative to a bracket unit (5) about a pivot axis (12) for adjustment of the steering column in an adjustment direction (11) for a height or tilt adjustment. The pivot axis (12) is formed by a spindle bolt (24) which can be mounted so as to be fixed with respect to the vehicle and which extends through a first and a second elongated hole (22, 23) of the adjustment unit (4). In the event of a vehicle crash, the adjustment unit (4) is displaceable relative to the spindle bolt (24) with displacement of the spindle bolt (24) in the elongated holes (22, 23), wherein, in a region situated between the first and the second elongated hole (22, 23) in relation to the direction of the pivot axis (12), there is arranged an energy absorption part (27) with which the spindle bolt (24), during the displacement thereof in the elongated holes (22, 23), interacts with plastic deformation of the energy absorption part (27) owing to exertion of pressure on the energy absorption part (27) and displacement of material of the energy absorption part (27).
