A device for sequentially switching at least one first and at least one second Venetian blind, the slats of which can each be synchronously rotationally moved by means of at least one coupling rod in order to open and close the blinds. The device includes an actuator for generating a rotational movement of the slats through 80° to 90°, a coupling for rotatably coupling the actuator to a slat of the first blind, a link rod which has a partially-circular link, and a transmission rod. The actuator has an eccentric pin parallel to its axis of rotation which engages in the partially-circular link of the link rod, and the linear movement of the link rod is transmitted to the coupling rod of the at least second blind.

This invention relates to a closing device for a housing of an air filter that can be closed with a housing cover. The assembly process is to be simplified and accelerated, while the number of parts required is to be reduced at the same time. According to the invention, this is achieved in that the housing cover and the housing can be connected to one another by means of a locking frame which surrounds the housing cover and the housing in the region of the housing edge, said locking frame being positionable in closed position by means of translatory motion, in which position it presses the housing cover onto the housing edge.
