Rocker arm mechanism for clamping an adjustable steering column

Abstract

A tilting pin mechanism is provided, preferably for the clamping device of a motor vehicle steering column, whose position is adjustable, for detachably fixing a housing accommodating the steering column at a bracket that is a rigid part of the body. The housing and the bracket have at least one cooperating friction surface pair that can be pressed against each other by means of the tilting pin mechanism. The tilting pin mechanism includes a centrally arranged bolt which is displaceable in the direction of its central longitudinal axis and with at least one tilting pin whose longitudinal axis is arranged approximately in parallel to the central longitudinal axis of the bolt. The tilting pin is supported on one side directly or indirectly at a bolt collar and is accommodated at its other end in a recess on the front side of an actuating ring. The tilting pin can be tilted into a lockable stop position and in the opposite direction into a release position by rotating the actuating ring beyond the axial extended position in parallel to the central longitudinal axis of the bolt. The actuating ring has at least one recess for an additional tilting pin on the second front side facing away from the first tilting pin. The other end of this tilting pin is supported in a thrust washer that is axially displaceable in the direction of the central axis of the actuating ring.
