Abstract

The invention relates to a link element of variable effective supporting length for the spring drive of a pivoting component, especially for the pivoting drive of a structural member of a vehicle folding top, which is articulated at a distance from the pivot axis of the pivoting component at one end on the pivoting component and at its other end on a countercomponent. The link element comprises an accumulator spring which can expand, with a change of the supporting length, and which can be regenerated by means of a backward pivoting movement of the pivoting component. The link element comprises a rigid link which is articulated elastically on the connecting component via the accumulator spring, with the result that the effective supporting length is variable within narrow limits.
