The invention relates to a hinge actuator comprising a first part which is configured for connection with a second part via an electric drive. The first and the second part are provided with stops cooperating in a pivoting direction for defining a select or predetermined position of the actuator parts with respect to each other. In an embodiment, in a first position of a coupling between the first part and the second part, these parts can pivot via the electric drive. In a second position, the first part and the second part are not connected via the drive but can be pivoted relative to each other manually. Further, the first and the second part may be provided with stops only cooperating in the second position of the coupling in an opposing pivoting direction, for defining the select or predetermined position.
