  • Device for lever operation of the air conditioning controls of an automobile
    Patent number: 4226138
    Abstract: A control arrangement with a single lever pivoting successively about two articulation axes. The lever is articulated on a fixed plate by the intermediary of at least one link. The link is articulated on the plate at a fixed axis while the lever is articulated on the link at an axis movable with respect to the plate and offset from the fixed axis. In this way, after the lever-link assembly has pivoted around the fixed axis, the link comes up against a stop on the plate so that the movable axis becomes fixed in its turn and the lever continues its travel pivoting about this axis.
