Motor vehicle steering column unit has adjustment units with spindle nut units screwed onto adjustment spindle and magnetically reactive armature plate that brakes when magnetic field applied

摘要

The device has a steering column in a housing, an electrically powered adjuster for longitudinal and inclination adjustment, an electrical drive unit, at least one adjustment unit on an adjustment spindle (5) and at least one adjustment mechanism for translating the longitudinal movement of the respective adjustment unit into a longitudinal or inclination movement of the steering column. Each adjustment unit has a spindle nut unit screwed onto the adjustment spindle with a magnetically reactive armature plate (20) that performs a braking action in the rotation direction when a magnetic field is applied.
