摘要： A steering column includes an adjusting unit that is fixedly clampable releasably to a supporting unit and in which a steering spindle is mounted rotatably about a longitudinal axis, a clamping device with a release position and a fixing position for locking the adjusting unit to the supporting unit, a clamping bolt arranged along a clamping axis and guided transversely with respect to the longitudinal axis through an elongated hole in the supporting unit extending in an adjustment direction and in which the clamping bolt in the release position is movable. A fixing element on the clamping bolt can be braced by the clamping device in the direction of the clamping axis against the supporting unit. A guide device may have guide elements on the fixing element and on the supporting unit that are spaced apart from the elongated hole, the fixing element being guided in the guide elements in a translational manner relative to the supporting unit.

摘要： A steering column has an actuating unit and retaining unit. A clamping device includes a clamping lever and a clamping shaft which are rotationally coupled and the clamping shaft has a cam which is connected to the clamping shaft in a rotationally fixed manner. A fixing device includes an arresting element and is arranged in the retaining unit. An engagement element is connected to the actuating unit. The cam and a guide track of the arresting element such that the arresting element can be brought into engagement with the engagement element by a rotary movement of the cam. The guide track has a first ramp region, a second ramp region and, situated therebetween, a transition region starting from which the ramp regions are formed, wherein the first ramp region is designed as a rising ramp, and the second ramp region comprises a falling ramp.
