Steering column damper has deformation device changeable from locking state with defined friction with respect to casing deformation tube and unlocking state with reduced friction

摘要

The device has a casing deformation tube (2) containing a sliding tube (6) concentric with its central longitudinal axis (3), a pivotable steering column (9) guided by the tubes and at least one deformation device (12) for deforming the casing deformation tube when the tubes move relative to each other. The deformation device can be changed by a control unit from a locking state with a defined friction with respect to the casing deformation tube and an unlocking state with reduced friction.
