Clamping device for a steering column

A clamping device for fixing a position of a vehicle steering column which is adjustable in length and/or inclination, comprising:

• a first clamping plate element and a second clamping plate element with a rolling body positioned in between;
• wherein said rolling body is accommodated in a hole in a guide element which is arranged between the first clamping plate element and the second clamping plate element;
• wherein the second clamping plate element is rotatable between a released position and a clamped position in relation to the first clamping plate element;
• wherein the second clamping plate element comprises a clamping ramp for the rolling body;
• wherein a surface of the first clamping plate element forms a plane, and the rolling body on the first clamping plate element rolls from the released position to the clamped position on the plane of the surface;
• wherein the clamping ramp comprises a contour on which the rolling body rolls when the second clamping plate element is rotated between the released position and the clamped position in relation to the first clamping plate element;
• and
• wherein the contour changes from the released position to the clamped position such that when the second clamping plate element is rotated between the released position and the clamped position in relation to the first clamping plate element a space between the first and the second clamping plate element is changed.
