Abstract

A lifting linkage for an upwardly pivotable vent panel in the roof structure of an automobile, where an upper and lower knee lever form a knee linkage which is detachable from the vent panel and adjustable in relation to the actuating rod by means of a high-friction slip fit. In the collapsed position the knee levers engage each other to prevent rattling.
