Patent attributes
An adjustable steering column for a motor vehicle includes a setting unit displaceable in at least one setting direction, a holding unit nondisplaceable in this setting direction, and a securement device. In the opened state of the securement device, the setting unit is displaceable with respect to the holding unit for setting the position of the steering column and, in the closed state of the securement device, the setting unit is secured with respect to the holding unit by the securement device. The securement device includes a clamp bolt penetrating openings in the setting unit and holding unit, at least one tooth plate penetrated by the clamp bolt, which tooth plate comprises at least one toothing (set of teeth) with teeth directed away from the clamp bolt. The holding unit has at least one toothing (set of teeth), facing the clamp bolt for cooperation with the at least one toothing of the tooth plate in the closed state of the securement device. The tooth plate is implemented elastically flexibly and disposed between the holding unit and a press-on part, penetrated by the longitudinal axis of the clamp bolt, by which it is pressed onto the holding unit in the closed state of the securement device. The at least one toothing of the tooth plate in the opened state of the securement device is spaced apart by spring force in the direction of the longitudinal axis of the clamp bolt from the at least one toothing of the holding unit.
