发明名称 Steering column for a motor vehicle
摘要 A clamping device for an adjustable steering column for a motor vehicle comprises a clamping bolt which is rotatable about its longitudinal axis for the opening and closing of the clamping device by means of an actuation lever, through an opening of which the clamping bolt extends. In the region of the opening of the actuation lever there is situated a connecting section of the clamping bolt, over the axial extent of which connecting section the clamping bolt is connected to the actuation lever by way of a press fit. The outer wall of the clamping bolt has, in the connecting section of the clamping bolt, at least two pressing regions which are spaced apart in the circumferential direction about the longitudinal axis and by way of which the actuation lever is pressed against the outer wall.

主权项 1. A steering column for a motor vehicle, the steering column comprising: a clamping device, in the open state of which the position of the steering column is adjustable and in the closed state of which the position of the steering column is fixed and which comprises a clamping bolt, which clamping bolt has a longitudinal axis, first and second ends which delimit the clamping bolt in an axial direction, and an outer wall which delimits the clamping bolt in a radial direction, wherein the clamping bolt is rotatable about its longitudinal axis for the opening and closing of the clamping device by means of an actuation lever, through an opening of which the clamping bolt extends, and wherein the clamping bolt has an end section adjoining its first end and has a connecting section which adjoins the end section in the direction of the second end of the clamping bolt and which is situated in the region of the opening of the actuation lever and in the axial extent of which the clamping bolt is connected to the actuation lever by way of a press fit, wherein the outer wall of the clamping bolt has, in the connecting section of the clamping bolt, at least two pressing regions which are spaced apart in the circumferential direction about the longitudinal axis and by way of which the actuation lever is pressed against the outer wall, and in that, as viewed in a longitudinal central section running through the pressing region, the outer wall of the clamping bolt has a smaller spacing from the longitudinal axis of the clamping bolt in each pressing region than at least over a part of that end section of the clamping bolt which adjoins the connecting section.
