1. An electric-adjustable steering column for a motor vehicle, the electric-adjustable steering column comprising:
an actuating unit, in which a steering spindle is mounted rotatably about a longitudinal axis (L) extending in the longitudinal direction;
a supporting unit, which is connectable to a motor vehicle body and in which the actuating unit is held so as to be displaceable in the longitudinal direction;
a motorized adjusting drive arranged between the supporting unit and the actuating unit; and
an energy absorption device, which is incorporated between the supporting unit and the actuating unit and has an elongate energy absorption element, fastened to the actuating unit or to the supporting unit via a fastening, and has a deformation member, which interacts with said energy absorption element, is attached to the supporting unit or to the actuating unit and, in the event of a crash with a relative displacement of actuating unit and supporting unit, brings about an energy-absorbing plastic deformation of the energy absorption element;
wherein the fastening has at least one fastening device that is offset-compensating in the longitudinal direction, wherein the offset-compensating fastening device has an elongated hole which extends in the longitudinal direction and through which a connecting element extends, and wherein the elongated hole and the connecting element are movable relative to each other and are configured to minimize resistance to their relative movement.
