Abstract: An adjustment device for adjusting an air inlet of a motor compartment of a motor vehicle between at least a first position in which the air inlet is substantially open and a second position in which the air inlet is substantially closed, comprising a drive unit for adjusting the air inlet between at least the first position and the second position, wherein the drive unit comprises a compound drive system.

Abstract: An adjustment device for adjusting an air inlet of a motor compartment of a motor vehicle between at least a first position in which the air inlet is substantially open and a second position in which the air inlet is substantially closed, comprising a drive unit for adjusting the air inlet between at least the first position and the second position, further comprising an auxiliary unit which is arranged for adjusting the air inlet in case of a calamity for bringing the air inlet to a predefined position, comprising at least one energy storage element.

Abstract: The invention relates to an adjustment device for adjusting shutoff elements of an air inlet of a motor compartment of a motor vehicle between at least a first position in which the air inlet is substantially closed and a second position in which the air inlet is substantially open. The adjustment device comprises a drive unit. The drive unit comprises a drive train, an electric motor with an output shaft for driving the drive train, and a drive shaft. The drive train comprises at least one reduction element. The reduction element, the output shaft of the electric motor, and the output shaft of the adjustment device form drive elements of the drive unit. The adjustment device is provided with a condition determining unit for determining a motion condition of at least one of the drive elements.

Abstract: Adjustment device for adjusting shutoff elements of an air inlet of a motor vehicle, wherein the shutoff elements are adjustable between an open position in which the air inlet is substantially open and a closed position in which the air inlet is substantially closed, includes a drive unit for adjusting the shutoff elements between at least the open position and the closed position, and a fail-safe mechanism which is arranged for adjusting the air inlet to a predefined position in case of a calamity situation. The adjustment device includes a blocking mechanism for blocking the operation of the fail-safe mechanism in predetermined situations, wherein in such predetermined situations the shutoff elements are adjustable to a predefined position without activation of the fail-safe mechanism.

Abstract: The invention relates to an adjustment device for adjusting shutoff strips of an at least partly closable air inlet of a motor compartment of a motor vehicle between at least a first position in which the shutoff strips leave the air inlet at least partly open and a second position in which the shutoff strips at least partly close the air inlet. The adjustment device comprises a drive unit, situated in a housing, which has a motor and a drive train with reduction stage. The drive train comprises an output shaft provided with a first coupling means facing outside the housing and a second coupling means facing outside the housing, opposite with respect to the first coupling means. The coupling means are configured to cooperate with, respectively, a first and a second coupling element of a first and second set of shutoff strips, respectively, for coupling the output shaft on both sides of the housing to the respective set of shutoff strips.
