Adjusting and fixing device for a steering shaft, whose height and/or length can be adjusted
First Claim
1. Adjusting mechanism for a steering shaft, which is disposed in a stationary mounting point in a vehicle so as to be slidable in the direction of the longitudinal axis of the steering shaft and pivotable in at least one direction disposed radially thereto, the telescopically extendable steering shaft being retained by means of bearings in a bearing part of a bearing element so as to be slidable in the longitudinal direction of the steering shaft with and/or relative to this bearing part and/or pivotable relative to the mount, and being fixedly retained by means of at least one fixing mechanism, and the fixing mechanism has a tensioning element extending transversely to the longitudinal axis of the steering shaft on which fixing mechanisms mutually adjustable by means of a lever are provided, at least one of which has respectively at least one base piece with at least one clamping element, at least one guide element and at least one resilient element, the clamping elements of which are designed to provide a clamp connection between the steering shaft or the bearing element and the mount, characterised in that at least one clamping element (96;

Abstract
The invention relates to an adjusting mechanism (3) for a steering shaft (2) for adjusting the length and/or inclination, and at least one fixing system (4) fixing the adjusted position, which has a tensioning element (24) extending transversely to the longitudinal axis of the steering shaft (2), on which fixing mechanisms (13; 14) are provided which can be adjusted relative to one another in the longitudinal direction by means of a lever (84), each having at least one base element with at least one clamping element, at least one guide element and at least one resilient element, in which at least one clamping element is disposed between the steering shaft (2) and the bearing element (10) and/or between the mount (5) and the lever (84), and in a locked position the clamping element or the clamping elements releasably fix the steering shaft (2) or the bearing element (10) and/or the mount (5) in its position relative to the tensioning element (24) against the action of the elastically deformable resilient element by means of an intermittent and/or linear friction connection.
