Abstract: A radiator shutter provided for the frontal arrangement at a motor vehicle shows two groups of lamellae, which are pivotally supported at opposite sides of a drive unit, each parallel in reference to a shutter frame. For a joint pivoting of the lamellae an entrainer tappet provided here at a distance from its bearing axis in the direction perpendicular in reference to the longitudinal direction of the lamellae, engages a common coupling element. For a simple production of the engagement of the bearing tappets of the lamellae in the shutter frame and its entrainer tappets in the coupling element they are latched in bearing recesses open perpendicular in reference to the bearing axis.

Abstract: The radiator shutter provided for the frontal arrangement at a motor vehicle shows two groups of lamellae (2-4, 5-7), which are pivotally supported at opposite sides of a drive unit (68), each parallel in reference to a shutter frame (9). For a joint pivoting of the lamellae (2-7) an entrainer tappet (99-104) provided here at a distance from its bearing axis (109) in the direction perpendicular in reference to the longitudinal direction of the lamellae, engages a common coupling element (98). For a simple production of the engagement of the bearing tappets of the lamellae in the shutter frame (9) and its entrainer tappets (99-104) in the coupling element (98) they are latched in bearing recesses (32-37) open perpendicular in reference to the bearing axis.

Abstract: The jalousie for the control of the air flow through the engine cooler of a vehicle has rotatable fins (2), which are supported on one side in an outer housing ring (47) provided for the connection with the engine cooler of the vehicle and on the other side in an inner supporting ring (4). The swivelling of the fins (2) occurs with an adjusting ring (45), whose engaging portions (46) work together with counter-engaging portions (10) provided at the fin ends. The adjusting ring (45) with its engaging portions (46) and the counter-engaging portions (10) of the fins (2) are enclosed together on all sides in a hollow space (49) circumferentially extending around along the adjusting ring (13, 45) for the protection against contaminants and consequently for its safe function, which is limited by two profile rings (47, 50) interlocking with each other all around.
